The technical FIELD TO WHICH the INVENTION RELATES.

The present invention, in General relates to an improved site with a fibrous layer for separation of the liquid particles with dissolved or suspended solids or without them) from gas streams. More specifically, it concerns a node with a fibrous layer having a superior ability to prevent re-entrainment of the collected liquid.

The prior art INVENTIONS

Teminological find wide use in applications where the aerosols, in particular, less than 3 microns must be separated from a stream of gas or vapor (hereinafter and in the claims together called "gas"). These teminological include fibrous layers, through which the gas flow to achieve separation. Some of the most frequent applications of teminological include the removal of mists acids, such as sulphuric acid mist, in the manufacturing methods of acid mists plasticizers when, for example, manufacturing of PVC floor and wall coatings, aerosols, water-soluble solids such as, for example, emissions from towers granulation of ammonium nitrate. When removing aerosols wetted soluble solids collected solids dissolved in the liquid inside the fibrous layer or wash off when it applies the scientific research Institute of irrigated fibrous layer or spraying liquid, such as water, introduced into the gas stream before the fibrous layer.

Re-entrainment of the collected liquid from the lower flow surface of the fibrous layer often causes problems. These problems may include any of the following individually or in combination: clogging of the bottom stream equipment of the way, a violation of the purity of the product, pipeline corrosion and, in some cases, difficulty in achieving the requirements of the selection. Re-entrainment separators with a fibrous layer can occur by two mechanisms. As the fluid flows down through the fibrous layer and/or back along the surface, the flow of the moving gas can cause the part of the flowing fluid to burst or bubble out of the downward liquid flow and re-return into the gas stream in the form of drops. This problem is especially noticeable at the bottom of a vertically positioned fibrous layer, since all the liquid collected fibrous layer, necessarily flows down to the bottom, and from a practical point of view, as the gas phase pulls the fluid from the rear along the surface at a bottom of a fibrous layer. At this point of release, where the highest total runoff, the delay in the gas phase can cause the formation of bubbles, "spray", jet spraying or fragmentation of the flowing fluid. When these userinitials, formed fragments and droplets size to submicron, which swept away the moving gas stream, which is called "bubble re-entrainment".

The second mechanism of re-entrainment, called "layer re-entrainment" occurs when the gas velocity in the layer is so high that the gas phase tighten the flowing liquid all over the fibrous layer at the bottom of the thread producing the surfaces of the fibrous layer, causing bubbling, splashing, spray atomization and fragmentation of re-entrainment. Thus, in a given fibrous layer and at a constant liquid load with increasing layer speed is reached the moment when the bubble re-entrainment. This first occurs at the bottom of a fibrous layer on the surface of the release of gas gathering environment. As the layer speed further increases, the re-entrainment begins to occur at higher levels of the fibrous layer with only a small increase in speed, re-entrainment occurs essentially on the entire surface of the gas outlet of the fibrous layer. This is usually referred to as total flooding.

Were made prior attempts to prevent re-entrainment and get to work fibrous layer in drier conditions through the removal of collected liquid and dissolved solids what's the substance of the fibrous layer. In one example, the tubular fibrous layer is formed from two or more shorter sections which are stacked one on top of another, forming a fibrous layer. The metal plate is placed between adjacent sections in this package, forming a barrier against the migration of fluid from one section to the next lower section, and causing the fluid to flow radially from sections (and of the fibrous layer). However, in this arrangement, the fluid may move out of the fibrous layer to producing (i.e. lower downstream) side of the fibrous layer. At this point, the chances of the liquid to be re-entrainment increases. In addition, it is difficult to maintain the necessary gas-tight seal between sections of a fibrous layer and a metal plate to prevent gas bypass between the section and the adjacent plate.

DETAILED description of the INVENTION

Referring now to the drawings and, in particular, in figure 1, the mist eliminator (usually denoted 1) m which can be placed in a flow line of the gas stream to remove aerosols and/or wetted soluble solids from the gas stream. The mist eliminator is a type that has particular application for use in gas flows with liquid aerosol content (especially where there are particles of an aerosol of liquid having sub-micron dimensions), which must be removed from the gas stream. The mist eliminator 1 includes a tank (usually denoted by 3), having a removable lid 5, which is tightly attached to the tank to close the open top of the tank. An annular mounting plate 7 inside the tank 3 tank parts on the upper chamber 9 and the lower chamber 11. The gas flow can pass from the lower chamber 11 to the upper chamber 9 through the Central hole 13 of the ring mounting plate 7. Tank 3 includes an input 15 of a gas stream for receiving the gas stream loaded with aerosols and/or wetted soluble solids in the lower chamber 11 of the tank and the outlet 17 of the filtered clean gas stream in a message fluid from the upper chamber 9 in the tank, allowing filtered clean gas to come out of the mist eliminator 1 in prom or other processing equipment (not shown).

The node with the fibrous layer, generally designated 19, is located in the lower chamber 11 of the tank 3 and has a generally tubular shape with a closed bottom and an open top. Node 19 with a fibrous layer is hermetically mounted on the mounting is the Department 1, so the open top of the site with a fibrous layer is combined with a Central hole 13 of the mounting plate. Gas cannot flow from the lower chamber 11 to the upper chamber 9, if it does not pass through the node 19 with a fibrous layer. Mounting plate 7 holds the node 19 with a fibrous layer inside the tank 3, so that the node with the fibrous layer hangs from the mounting plate. Node 19 with a fibrous layer removes a very high percentage of aerosols and/or wetted soluble solids from a gas stream flowing at the bottom of the tank 3. External waste pipe 21 near the bottom of the tank 3 produces liquid and/or wetted soluble and dissolved solids are collected on the bottom of the tank.

Shown in figure 1, the mist eliminator 1 represents a straight or hanging type mist eliminator. Also known teminological other structures, such as aboutnational or "standing" mist eliminator where the gas flows from the interior of the Central core element to the outside, or the mist eliminator flat layer (not shown). Can also be used nodes with concentric fibrous layer having concentric flow and Obratnaya fibrous layers. The present invention can be used with various forms of teminological, including all the above teminological.

Addressing the er to figure 2, node 19 with a fibrous layer flow mist eliminator 1 includes waste rack 25, which is above the bottom of the tank 3. Waste hour 25 contains waste pipe 25A, round bottom plate 25 and the passage 25C propagating through the waste pipe and opening at the bottom of the plate. The passage 25 opens into the tank 3 to drain the collected liquids and particles removed from the gas stream node 19 with a fibrous layer. Liquid and wetted or dissolved soluble solids collected at the bottom of the tank 3, flow through the drain 21. The liquid level at the bottom of the tank 3 provides a gas valve, allowing fluid collected in the node 19 with a fibrous layer to drain through the drainage pipe 25A at the bottom of the tank.

The internal screen and the external screen (usually denoted by 27 and 29, respectively) extend from the bottom plate 25 to the mounting plate 7 and are arranged concentrically in the radial spatial relation. Together, the internal and external screens 27, 29 form the wall in the shown embodiment, which separates the inner medullary (rear along) the space 31 inside the inner screen 27 from the outside (front along) space 33 inside the tank 3, but outside the inner screen 27. It will be understood that the wall may be constructed in other ways (for example, to have only Odie the screen or no screen} without deviating from the scope of the present invention. Internal and external screens 27, 29 typically have a mesh structure, so that each of them defines a relatively large openings that will allow the gas to flow normally to move freely through the inner and outer screens between core inner space 31 and the external space 33. Screens 27, 29 are connected with the annular flange, which is located on the upper side of the annular mounting plate 7. The annular flange 34 attached to the mounting plate 7 and holds the screens 27, 29 and a drain rack 25. In the shown embodiment, the inner screen 27, the external screen 29 and the annular flange 34 are fibrous support layer. It should be understood that other structures to maintain the fibrous layer can be used without deviating from the scope of the present invention.

The fibrous layer (usually denoted 35) node 19 with a fibrous layer is in the radial space between the inner and outer screens 27, 29 and substantially fills the space and closes the openings in the screens, so that the gas stream must pass through the fibrous layer to move from the external space 33 surrounding the site 19 with a fibrous layer in the core interior space 31 inside the node 19 with a fibrous layer (see figure 1). The fibrous layer 35 is typically trobc the th form and effectively sealed at opposite ends to the mounting plate 7 and the bottom plate 25 In the waste rack 25 by way well-known specialists in the field of technology, so that the gas does not overlook the fibrous layer, flowing from the external space 33 in the tank 3 in the core interior space 31.

Referring now to figure 3 and 4 shows that the fibrous layer 35 includes collecting fibrous medium 39 and drainage fibrous environment 41 (both reference position usually indicate these objects). Collecting fibrous medium 39 is formed of a suitable material, such as not matted layer of randomly distributed fibers having an average diameter of approximately 0.5 to 15 microns, Packed with substantially uniform porosity layer from about 85 to 98 percent. Random fiber will be supported with a wire screen (not shown). As another example, collecting fibrous medium 39 may be a needle-punched Mat made from fibers having an average diameter of approximately 0.5 to 15 microns, molded to substantially uniform porosity layer from about 85 to 98 percent, which eliminates the need to support an additional screen. The drawings show collecting fibrous environment 39 in the form of such a needle-punched Mat, extending essentially the full height of the node 19 with a fibrous layer. Collecting fibrous medium 39 may be formed from a variety of t the fir mats (not shown). The weight of the fiber can be Packed between the opposite legs 27, 29, forming a collecting fibrous medium. Additionally, collecting fibrous environment can also be minimized structure of the type shown in jointly directed application U.S. serial number 11/031820 registered 7 January 2005, the description of which is included here by reference. For simplicity of illustration collecting fibrous medium 39 is shown as a single Mat.

The arrows in figure 3 and 4 indicate the direction of flow of the gas stream through the node 19 with a fibrous layer. Figures 3 and 4 schematically depict a section showing the composition of a fibrous layer 35. The gaps shown between the fibrous layer 35 and the inner screen 27, and the gaps between other components of the fibrous layer will not be present in the real structure of the fibrous layer. However, they are given for ease and clarity of the individual components and routes the collected liquid. For the purposes of this description, references to "on the bottom on the ceiling" and "upper stream" indicate total relative location of components relative to the typical direction of the gas flowing through the node 19 with a fibrous layer. They do not require that these components were in contact with each other or even directly neighbored to each other (i.e. can the present intermediate structure).

Drainage environment 41 contains skipping strip 45, located at the height of the fibrous layer 35. Skipping strip 45 includes a mechanical transmission bands at the top and bottom fibrous layer 35, which are annular in shape, extending around a fibrous layer. Between the ends of the permeable strip 45 can be formed by winding a single piece of material spiral around the inner screen 27. Possible other locations within the scope of the present invention. For example, and without limitation, many pieces of material can be used for the formation of spiral wrap, or each drainage zone can be an individual, a collapsed ring with a piece of material. For the purposes of this description each turn of the spiral winding is considered "passing lane". In addition, each band may be formed from multiple layers of material (not shown). In the shown embodiment, all transmissive strips 45 are asking area overlapping (generally designated 47), where one of the pass bands overlap of adjacent pass bands. One type of material suitable for passing lanes may be, for example, thin needle-punched fiber Mat having fibers with an average diameter of about 3-20 microns, formed with things is actually homogeneous porosity layer from about 85 to 98 percent. The average diameter of the fibers and the porosity of the layer is preferably chosen so that at the present rate of gas and aerosol load this environment will not choke collected in the liquid phase, and the residual saturation of the environment without delaying the gas phase Rvless than the residual saturation without gravitational flow of the liquid phase (Rg). Residual saturation without tightening the gas phase (Rv) is a measure of the characteristics of the environment to hold liquid and/or soluble solids) within the environment, when the gas flows through the environment in the given conditions, trying to push fluid from the environment in the direction of gas flow. Residual saturation without gravity currents (Rg) is a measure of the ability of the environment to hold liquid and/or soluble solids) against gravity. These parameters residual saturation and methods of their determination are described in U.S. patent No. 4086070, the description of which is included here by reference.

Drainage medium 41 has additional components that are usually located on the lower stream side of the transmissive strips 45. In the shown embodiment, the drainage environment includes many drainage layers 49 full length or Mat, usually overlapping each other and extending over the entire length of fibrous SL is I 35. It will be understood that other configurations are possible drainage layers 49, including the lack of drainage layers, any number of such layers (including only a single layer) or the presence of drainage layers, extending less than the full height of the fibrous layer 35. Ring cover 50 protrudes downward from the flange 34 and facilitates sealing of the fibrous layer 35 at the apex, suppressing the bypass gas filter layer. The inner screen 27 is attached to the cover 50 by welding. Drainage environment 41 further includes a drainage strip 51. Part of the drainage strips 51 are arranged in regions overlapping 47, asked transmissive strips 45 and are positioned between adjacent overlapping transmission bands in the regions of overlap. Material drainage strips 51 may be, for example, chemically modified, fibrous Mat of fibers having an average diameter of approximately 20-35 microns formed with essentially uniform porosity layer from about 85 to 99 percent. The average diameter of the fibers and the porosity of the layer is preferably chosen so that the residual saturation of the environment without delaying the liquid phase in the gas phase is greater than the residual saturation without gravitational flow of the liquid phase (i.e. Rg<Rv). Drainage layers 49 can be made from the same or other drainage mA is Arial, that and drainage strip 51.

Drainage strip 51 can be formed by spiral winding on the inner screen 27 simultaneously with the winding of the transmissive strips 45. In this case, each turn of the spiral defines one of the drainage strips 51. Other ways of forming the drain strips 51 may be used without deviating from the scope of the present invention. Although drainage strip 51 is shown as having a height that is only slightly larger than skipping strip 45, one or more drainage strips can be clearly speaking of the field relative overlapping 47 to the bottom of the fibrous layer 35.

As a result of this construction the lower end 53 of each of the transmissive strips 45 is located over a part of the drainage strips 51, so that liquid flowing from skipping strip passes directly to the drainage strip. Similarly, the lower end 55 of each of the drainage strips 51 is typically located over the portion of the next lower drainage strip. The liquid may drip from each drainage strip 51 or on adjacent drainage layers 49 on the lower stream side of the drainage strips or leaving the drainage strip at its lower end 55, the following drainage strip. This design helps to suppress the rise of the liquid in passing the strips 45. In the collecting fiber environment 39 working with a smaller number W is drasti in the intermediate empty space inside the collecting fiber environment. Among the advantages of this alternative implementation of the present invention include reducing re-entrainment of liquid and/or soluble solids captured fibrous layer 35. This is achieved with a relatively small pressure drop through the node 19 with a fibrous layer. In addition, the collection efficiency of submicron particles is improved because collecting fibrous medium 39 is open land.

According to figure 4, the node 19 with a fibrous layer optionally contains an additional drain insert, designated generally 59. The drainage box is located near the bottom of the fibrous layer 35 and extends to a height which is approximately one third of the way up the fibrous layer. In this embodiment, the tip of the drain insert 59 may be approximately one third to half way up the height of the fibrous layer 35. The height and location of drainage inserts can be other than described, while remaining within the scope of the present invention. Drainage box 59 includes a support screen 61 and two Mat 63 of the drainage material. It should be understood that one Mat 63 or more than two mats can be used within the scope of the present invention. Drainage material mats 63 may be, for example, chemically modified, fibrous Mat of fibers having an average diameter of arr is siteline 20-35 microns, educated with essentially uniform porosity layer from about 85 to 99 percent. The average diameter of the fibers and the porosity of the layer is preferably chosen so that the residual saturation of the environment without delaying the liquid phase in the gas phase is greater than the residual saturation without gravitational flow of the liquid phase (i.e. Rg<Rv). The reference screen 61 is of generally the same design as the internal and external screens 27, 29, except that it is shorter in height. The number of mats may be other than two, within the scope of the present invention. Drainage box 59 provides a significant additional drain tank near the bottom of the fibrous layer 35, where you have to control a higher flow of liquid from the liquid, which flows down from the higher part of the fibrous layer and is collected in the lower part of the fibrous layer. Another advantage of the drain insert 59 is implemented, if the lower part of the collecting fiber environment 39 fibrous layer 35 includes areas with a low packing density. In this case, the drain insert 59 will help reduce local re-entrainment caused by the higher velocity of the gas, the current preferably through areas with a low packing density in collecting environment 39.

Also according to figure 4 the annular cover 67 protrudes upwards from the bottom clause is required 25V on the lower stream side of the drainage layers 49 near the inner screen 27. The internal screen is attached to the cover 67 by welding. The cover 67 is solid and blocks the radial gas flow after cover. Usually disc-shaped drain gasket 69, located on the lower stream side of the cover 67, extends upward from the bottom plate 25 to the space above the top cover. For example, the height of the drainage strip 69 may be approximately twice the height of the cover 67. In the shown embodiment, the drainage box 59 rests on top of the drainage strip 69. Drainage strip is made of a suitable material such as wire mesh stainless steel wire diameter to 0.011 inches with a density of from 5 to 12 pounds per cubic foot. The fluid tends to accumulate inside the fibrous layer 35 and the drain environment 41 near the bottom of the fibrous layer. In flooded conditions the gas flow can push the liquid inside the rear on the go, the core of the internal space 31, possibly causing re-entrainment with the gas stream. However, the drain insert 59 and drain gasket 69 pose a radial flow of liquid poured over the top of the cover 67. As the liquid moves down inside the drain insert 59 and drainage strip 69 in combination with the cover 67, the fluid is protected from radial gas flow, so that W is dcost can drain to the bottom of the drain insert and drainage strip without re-entrainment with the gas stream. A similar structure, which includes the cover (or "reflective plate"), shown in U.S. patent No. 4053290, the description of which is included here by reference.

As an additional protection against re-entrainment of the insert re-entrainment (more accurately "collection item re gone fluid, which may be selected from the family of normal shock device located at least partially in the core of the internal space 31 of the node 19 with a fibrous layer. In the shown embodiment in figure 1-4 box re-entrainment is a mesh gasket 73. Mesh strip 73 is located approximately one-third of the way down from the top of the fibrous layer 35 and separates the core interior space 31 on the top and bottom. The gas which passes through the fibrous layer 35 in the inner space below or mesh strip 73, must pass through the mesh strip before passing through the Central hole 13 in the upper chamber 9. In one embodiment, mesh lining made from wire 11 mils thick and has a density of approximately from 5 to 12 lb/ft3. Mesh strip 73 has about 3 to 6 inches thickness in the shown embodiment. The mesh lining can be a simple mesh gasket (as the show is but) or jointly associated mesh gasket (not shown). Jointly associated mesh gaskets are thinner fibers associated with the primary fibers of the wire mesh. As used in the claims, "mesh lining" can be a simple strip, linked together by a mesh material or other porous gasket.

Preferably the mesh strip 73 is located inside the unit 19 with a fibrous layer in the place where the gas core velocity lies in the range from approximately 400 to 700 feet per minute (lb/min). Together knitted mesh gasket (not shown) typically operates at lower gas core speeds. Possible other locations, but the location in places where the gas velocity below the maximum (for example, lower than about 700 F./min), provides the best work mesh strip 73 to remove any liquid which otherwise may again be carried away with the gas stream after it passes through the fibrous layer 35. The most likely area of the fibrous layer 35, from which the liquid can again be carried away, is the lower part of the fibrous layer. This is because the liquid flows down the inside of the fibrous layer 35 under the action of gravity and tends to accumulate at the bottom. The liquid entrained in the mesh strip 73 may migrate from the insertion into the drain Proclus is the corporate governance 69 and then from node 19 with a fibrous layer through the passage 25C. Preferably the mesh strip 73 creates an additional pressure drop of less than one inch of water column. A weak increase in back pressure at the bottom of the fibrous layer 35 in the desired manner makes some additional amount of gas flow to flow through the upper part of the fibrous layer, which tends to be more dry during operation. Consequently, it is less common re-entrainment, as is a smaller gas flow at the bottom, including the bottom of a fibrous layer, which is more humid at work, and the greater the gas flow in the upper layer, which is more dry during operation.

In addition or instead of the mesh strip 73 insert re-entrainment may include Chevron (or separator pad). Figure 6 depicts the mist eliminator 1', having essentially the same design as the mist eliminator 1, except that Chevron 75' is used in addition to the mesh strip 73'. Part of the mist eliminator 1', the corresponding parts of the mist eliminator 1, will have the same reference position with the addition of a trailing stroke. Chevron 75' contains a series of separator plates generally V-shape and are connected together by a linked structure, and is usually a disk shape that is similar to the mesh lining. Possibly the s other forms of Chevron within the scope of the present invention. The separation plate may, for example, to have clearances from 0.75 to 4 inches (19 to 102 mm). Chevron 75' preferably is located in the medullary space 31' fibrous layer where the gas core velocity is approximately from 900 to 1500 F./min. In a typical case, the pressure drop through the Chevron may be from 0.1 to 2 inches of water column (from 2 to 50 mm of water column). Chevron 75' is above the mesh strip 73' in the inner medullary space 31'. Combination mesh strip 73' and Chevron 75' makes possible a higher working the core gas velocity and provides enhanced removal of smaller particles from the gas stream. It will be understood that the mesh strip 73' may be placed before Chevron 75', even though this could place a mesh lining outside its optimal operating range core gas velocity. In this case, the mesh strip 73' will act as a pre-filter or pre-coagulator for Chevron 75'.

Figure 5 shows the node 119 with a fibrous layer of the second variant of implementation of the present invention containing fibrous support layer formed of the inner screen 127 and the external screen 129, and the fibrous layer 135 (all reference position, usually indicate their interest). Part of the node 119 with a fibrous layer of the WTO the CSOs variant implementation, corresponding parts of the first variant of implementation, are given with the same reference positions plus "100". The fibrous layer 135 includes collecting fibrous environment 139, which may be formed essentially in the same manner as described for collecting fibrous medium in the first embodiment, and is depicted as a single Mat of fibrous material. The fibrous layer 135 additionally includes prefilter medium (generally designated 140) on the upper stream side of the collecting fiber environment 139 and polyfilters environment (usually labeled 141) on the lower stream side of the collecting fiber environment.

Przefiltrowane environment 140 is preferably formed in the shown embodiment, to remove large particles from the gas stream (for example, about 1 micron or more). Accordingly, large particles never reach the primary collecting fibrous environment 139, keeping it drier. Przefiltrowane environment 140 includes collecting fibrous strip 142, together forming a collecting fiber layer. Przefiltrowane environment 140 further comprises a drainage strip 144, together forming a drainage layer. Collecting fibrous strip 142 is made of a suitable material, such as needle-punched fiber Mat having fibers with the one diameter of about 3-20 microns, formed with essentially uniform porosity layer from about 85 to 98 percent. The average diameter of the fibers and the porosity of the layer is preferably chosen so that at a given gas velocity and aerosol load this environment is not breathless collected in the liquid phase, and residual saturation collecting fibrous bands 142 without pulling in the liquid phase in the gas phase is less than the residual saturation without gravitational flow of the liquid phase (i.e. Rv<Rg). Collecting fibrous material in the bands 142 removes liquid droplets from the gas stream. The flow directions of gas flow indicated by arrows in figure 5. Drainage strip 144 is made of a suitable material, such as chemically bonded, fibrous Mat of fibers having an average diameter of approximately 20-35 microns, formed with essentially uniform porosity layer from about 85 to 99 percent. The average diameter of the fibers and the porosity of the layer is preferably chosen so that the residual saturation of the environment without delaying the liquid phase in the gas phase is greater than the residual saturation without gravitational flow of the liquid phase (i.e. Rg<Rv). Node 119 with a fibrous layer, shown in figure 5, is a tube like site 19 with a fibrous layer in Fig.1-4. However, the design of figure 5 also makes use of the other applications, such as a flat layer.

Collecting fibrous strips 142 are asking area overlapping (generally designated 146), where one of the strips of collecting fibrous material overlaps the adjacent strip of collecting fibrous material. It will be clear that each strip may be formed from one or more layers of material. As schematically shown in figure 5, each strip 142 has one layer. The bottom of each drainage strip 144 is located in the corresponding areas of the overlapping 146 and facing toward the upper stream side of the fibrous layer 135. The drainage layer may include other layers (not shown) in addition to the drainage strips 144. These other layers may extend the entire height of the fibrous layer. During the application collects fibrous strip 142 capture the liquid and wetted soluble solids from the gas stream. Collecting fibrous strips 142 are relatively thin in comparison with collecting fibrous environment 139. The captured fluid tends to move essentially horizontally under the influence of the gas flow inside the collecting fibrous strips 142. This fluid enters directly the lower stream drainage strip 144, where the fluid moves down due to gravity. The lower ends of the collecting fiber p the Los 142 and drain strips 144 is turned to the upper stream side of the fibrous layer 135 at the lower ends of the respective areas of overlap 146. The assembled liquid in the collecting fibrous bands 142 and drain strips 144 dripping on the upper stream side of the fibrous layer 135. Since large droplets dripping from the environment, tends to be removed primarily by gravity rather than moving back into the environment under the action of the gas, less fluid is present in the gas stream, which is included in the primary collecting fibrous environment 139, keeping it drier at work. As a General rule, liquids and soluble solids in the gas stream is less likely to undergo re-entrainment, when passing through the fibrous layer of the filter operating in the state, closer to the dry (less moistened filter).

Polarimetry drainage environment 141 also helps to keep collecting fibrous environment 139 drier, promoting good flow from the collecting fiber environment. Polarimetry environment 141 includes polarimetrie collecting fibrous permeable strip 150, which are relatively thin with primary collecting fibrous environment 139. Polarimetrie collecting fibrous permeable strip 150 can be formed, for example, of the same material as prefiltration collecting fibrous strip 142. It will be clear that prefiltration collecting fibrous strips 142 and polarimetrie the fleecing permeable fibrous bands may be made of different materials. Although each collecting fibrous permeable strip 150 is shown as having only one layer, each strip may include multiple layers of material. The bottom edge of each collecting fibrous permeable strip 150 is overlapped with the neighboring polyfilters collecting fibrous permeable strip forming region 152 overlapping. Polarimetry environment 141 additionally includes polarimetrie drainage strips 154, usually located on the lower stream side polyfilters collecting fibrous permeable strips 150. Polarimetrie drainage strip 154 is made of a suitable material, such as the same material from which made prefiltration drainage strip 144. It will be clear that prefiltration drainage strips 144 and polarimetrie drainage strip 154 may be made of different materials. Polarimetrie drainage strip 154 is shown as containing a single layer, but more than one layer can be used within the scope of the present invention. The upper edge polyfilters drainage strips 154 are distributed in a region 152 of overlap formed by using neighboring polyfilters collecting fibrous permeable strips 150. The lower ends of the collecting fiber transmissive strips 150 and drainage strips 154 are back in the course of going to the soup fibrous environment 139. Additional polarimetrie drainage layers 156, each of which extends over the entire height of the fibrous layer 135 are behind the course from polyfilters drainage strips 154. However, these additional polarimetrie drainage layers 156 may be omitted without deviating from the scope of the present invention.

When using polarimetrie strip collecting fibrous material help to direct the fluid from the emitting surface of the primary collecting fibrous environment 139. This is because Rvfor polyfilters transmissive strips 150 collecting fibrous material has the same order of magnitude as Rvprimary collecting layer 139, and for transmitting strips 150 and primary collecting fiber 139 Rv<Rg. The liquid migrates generally horizontally through polarimetrie strip collecting fibrous material in the adjacent drainage strip. In drainage strips the fluid moves more vertically under the action of gravity to the lower ends of the drainage strips. Here, the liquid drips on the lower stream side of the collecting fiber environment. The ability of a liquid to drip from the drain strips helps to avoid saturation of the fibrous permeable strips 150, drainage strips 154 and drain layers 156.

Additional structure, such a spacecraft the drainage box 59, drain gasket 69 and paste re-entrainment 73 node 19 with a fibrous layer of the first variant implementation, can be used in the node 119 with a fibrous layer of the second variant implementation. Any one or all of these structures can be used. Part of the drainage insert 159 shown in figure 5, including a support screen 161 and two mats of drainage material 163 located between the support screen and the inner screen 127. Drainage box 159, shown in figure 5, a similar configuration of the drainage box 59, shown in figure 4.

The present invention provides advantages in filtering liquids and soluble solids from gas streams. In one embodiment, the mist eliminator includes a node with a fibrous layer of the present invention can operate at higher velocities of gas flow and at high aerosol loadings than previously. For example, the mist eliminator can operate at speeds greater than approximately 50 feet per minute, where the load of the gas flow of the spray liquid is greater than about 100 mg/f3. It is believed that the reduction of the discharge of fog and wetted soluble solids greatly intensified. In particular, the removal efficiency of submicron particles in the gas stream in the primary collecting environment is improving, so it is to collect environment supported drier through better drainage and pre-filtration of large particles. More collecting dry environment capable of capturing submicron particles by Brownian diffusion mechanism. Pre-filtering and/or improved drainage to prevent or delay the start of flooded conditions in the fibrous layer, so avoiding re-entrainment by the formation of bubbles, spray, jet spray, or fragmentation. In addition, the use of drain insertion, drainage strip and insert re-entrainment reduces the effect of flooded conditions by capturing liquids and soluble solids leaving the producing side of the drainage layers. Also, these improvements are achieved with a small additional pressure drop through the site with a fibrous layer, so that less energy (and therefore less costs) is required for mist eliminator. The above advantages are realized without creating many connections that must be carefully sealed to avoid gas bypass. Other embodiments of the present invention may have other advantages or include only some of the above mentioned advantages.
