Art

Known filtering and coalescense device that is part of the installation dehydration and bessoleva acetami, overlying the working section of the device.

The performance of such devices will be heavily influenced by the area of the input surface vlagotrebovatelnogo package. The package is installed in the cross section of the apparatus, therefore, the area of the input surface permeable to the flow of the emulsion, due to the diameter of the device is relatively small, which affects the performance of the device.

As a prototype of the proposed device passed device for separating emulsions (U.S. Pat. RF N 2065762, 01 D 17/04, publ. 27.08.1996 year). Known apparatus includes a horizontal cylindrical body and located it coalescense device in the form of sectional package installed at an angle to the horizontal axis of the device is not below the angle ettekanne liquid.

In the prototype, as in the analogue, coalescing package is installed in the cross section of the apparatus. This installation package defines the flow of the emulsion through the input surface of the package, the volume flow is limited by the cross-sectional area of the housing. The performance of the specified device when setting colesterolo package low.

The essence Yemenis ensuring the uniformity of loading colesterolo package.

The problem is solved in that in the apparatus for separating emulsions containing horizontal case with connections to the input of the emulsion, o dehydrated product and withdrawal of the aqueous phase and placed in the enclosure coalescing package according to the invention coalescing package is installed in an oblique-longitudinal section of the casing, a pipe entering the emulsion extended in the volume of the shell along colesterolo package and under it and is made in the form of a tubular manifold with perforation, with area under cholesterosis service is divided into sections by transversely installed partitions, the overlapping volume of the enclosure from the entrance surface colesterolo package to the bottom of the interface and is made in the lower part on the depth of the interface with the reporting section of the slits.

In existing devices division neptunomonas emulsion cholesteremia packages are installed in the cross section of the housing. The installation package according to the claimed solution in an oblique-longitudinal section of the body allows to increase the area of the input surface of the package and thereby increase the flow passing through the packet emulsion, which leads to improved performance of the apparatus as a whole. Od the wah separation of the emulsion, containing this type packages, the problem of distribution of the liquid inside the device and uneven loading colesterolo package throughout the volume. This problem is attributable to the following.

When installing colesterolo package in longitudinal section of the hull loss of flushing water from neptunomonas emulsion occurs along the entire length of the apparatus. The pipe or pipes of the drainage of the aqueous phase, usually placed in the apparatus in a certain part, and, in particular, it is advisable to place them on the opposite from the connection of the input of the emulsion the end of the apparatus. Conclusion dehydrated product must be made in the upper part of the body. In the process of opening of the throttle valve regulating the drainage of the aqueous phase, the movement is supplied to the apparatus emulsion rinse water that fell from the emulsion under cholesterosis service, the flow of the emulsion in the amount of coalescense package and movement of oil on the package is geared towards the conclusion of machine oil and kolestiramina water. Under these conditions, coalescing package will be uploaded throughout the volume is uneven: piece package, located closer to the conclusion of machine oil and water, overloaded, as part of the package, located in protivopul is from the emulsion under cholesterosis service, and water, kolestiramina in the process of passing the emulsion through a package, in liquid flows is a movement in the opposite direction. Work systems "in phase", i.e. the opening and closing of the valves of the conclusion drawn from the emulsion wash and kolestiramina water, affects the pressure inside the apparatus is shaken by all the internal threads in the system. All this greatly reduces the work opportunities colesterolo package, has a negative impact on his work, especially the congested part of the package, leads to rapid wear of this part, reduces the quality of the emulsion separation.

In the claimed invention solved this contradiction and at the same time to increase production apparatus provided with a uniform load longitudinally installed colesterolo package throughout its volume and excluded the impact on the service system work "phases". This is achieved by the connection of the input of the emulsion extended in the volume of the shell and is made in the form of a tubular manifold with perforation, which promotes uniform flow of the emulsion throughout the volume colesterolo package. When this device is made with a separation zone under cholesterosis service into sections by transversely installed partitions, Percy collector is passed through a septum and opens in each section, a certain number of output holes. Thus, ensured smooth flow of the emulsion in each section. However, the claimed solution is characterized by the fact that the lower part of each partition on the depth of the interface is made with slots providing communication between the sections, excluding the effect of the trap and to allow equalization of pressure in various parts of the apparatus. The degree of alignment of the pressure will be greatest if the slits to perform vertical and open from the aqueous phase, which also prevents hydraulic lock when the drainage system of the apparatus of the washing water.

The lower border of the partitions in the device preferably horizontally and at the same time to ensure that the combination of the top lines of the slots with the upper interface and the lower line of the slots and lower boundary walls on the lower level interface. This design of the device and installation of partitions allows you to smooth out the pressure pulsations and eliminate re-mixing of the wash water with the oil system "phases".

In the specific case of realization of the device horizontal cylindrical body is made. This embodiment of the chassis is the most rational. This partitions vylovili the following: the division apparatus primarily neptunomonas emulsion is shared along the entire length of the device area dropped out of the emulsion rinse water, common along the entire length of the apparatus of the settled areas of oil and water, kolestiramina in the process of passing the emulsion through a package, a single coalescing package, however, the area under cholesterosis service to the lower level of separation of the phases can be roughly represented as a sum of individual separators emulsion. As a result the technical result, which is to equalize the pressure in various parts of the apparatus and in the uniformity of loading colesterolo package throughout its volume, regardless of how the device is placed nozzles the separated phases and independently of the operation of the system partition phases: oil-water emulsion is precipitated from the emulsion wash water. Analysis of the known prior art has not revealed the technical solutions, which would have the same technical result due to the above set of features or any of the above signs.

List of drawings

The invention is illustrated by drawings, where

in Fig. 1 shows a device for separating emulsions, longitudinal section;

in Fig. 2 - section a-a in Fig. 1.

Information confirming the possibility of the image is the UBK input emulsion 2 in the form of a tubular manifold and nozzles conclusion dehydrated product 3 and output the aqueous phase 4. Tubular manifold 2 is made with perforations 5, open at the side wall of the housing 1. In the case in oblique-longitudinal section has a coalescing pack 6. The space between the bottom edge of the input surface colesterolo package 6 and the wall of the housing 1 is blocked impervious to water and oil baffle 7. The height of the impermeable partition 7 is slightly above the upper level of the 8 phases. Under cholesterosis package 6 in the zone formed by the entrance surface colesterolo package, the wall of the housing 1 and the lower layer section 9 phases, mounted transverse partitions 10, made in the form of metal plates segmental form and separating the enclosure volume 1 section 11. At the bottom of each partition 10, the lower edge of which is located horizontally and aligned with the line of the lower level interface, made vertical slits 12, open from the aqueous phase. The height of the slot 12 corresponds to the distance between the bottom 9 and the upper 8 levels of separation of the phases. The conclusion of the washing water falling from the emulsion under cholesterosis service, and water, kolestiramina in volume colesterolo package, where congestion is in the pocket 13, automatically opening d is and the lower and upper levels of separation of the phases from the input surface colesterolo package 6. The open-close valve 15 is carried out according to the indications of the sensors 18 and 19, which are mounted on upper and lower levels of separation of the phases from the output surface colesterolo package 6. For output kolestiramina water made the pipe 20.

Apparatus for separating emulsions is as follows.

Oil-water emulsion enters the casing 1 through the tubular manifold 2 and is evenly distributed throughout the housing 1 in sections 11 through the perforations 5. Flowing from collector emulsion enters the wall of the housing 1, resulting in the conversion of turbulence in the fed flow of the emulsion in laminar its movement. In each section 11 shared emulsion passes its plot colesterolo package 6, the volume of which is the coalescence of drops of water and its subsequent runoff into the pocket 13 collection kolestiramina water and its removal through pipe 20. Thus, each section 11 operates as a separate unit of the emulsion separation with his input of raw materials from the common header 2 and part colesterolo package 6. At the same time koalitsiyasi package 6 and the space above it remain common to all sections. The space below the interface zone is the emulsion rinse water from each section 11 is deposited in the General area and out of the apparatus through the pipe 4 upon actuation of the sensor 17 of the upper interface and, accordingly, when opening the valve 14. "Rocking" the internal fluid flows in the apparatus caused by the opening and closing of the valve 14, is extinguished by partitions 10 and the slits 12, made in the lower part of the walls 10, with smoothed pressure pulsations and ensures uniform loading colesterolo package throughout its volume. However, the slits 12 exclude the effect of the trap when the system is draining wash water from the apparatus.
