FIELD: process engineering.
SUBSTANCE: invention relates to method of making regular packing for mass exchange processes in absorption and rectification columns. In making packing layer, first, carcass should be made. Its elements may be fabricated from metall rods, angles, hollow tubes or wire, as well as from woven cables or other nonmetallic materials with proper resistance to media of their use. Packing elements representing horizontal corrugated tapes and screen flat vertical metal sheets are secured on said carcass. Said tapes may be made from both metal and plastics, or chemically and mechanically resistant fabric. Thickness of rods may be decreased as well as packing hydraulic resistance.
EFFECT: higher efficiency of heat-and-mass exchange, simplified design, reduced consumption of materials.
The invention relates to a method of manufacturing a regular nozzle for apparatus intended for carrying out mass transfer processes in the gas (vapor) - liquid, in particular for absorption and distillation columns.
In the patent of Russian Federation №2290992 described method of creating a layer of nozzles by falling asleep in a column apparatus elements nozzles, made in the form of parallel cylinders, which are formed by cutting elements arranged in a row height, curved circumferentially alternately inward and outward. When the cylinders are connected by bridges and positioned relative to each other so that their median plane to form a side surface of the right multi-faceted prism.
The invention improves the efficiency of heat transfer due to uniform distribution of the interfacial surface volume of heat and mass exchange apparatus.
This method, as proposed, allows you to create a packing layer for the implementation of the processes of heat and mass transfer of individual elements.
The disadvantage of the above method lies in the increased complexity of manufacturing the nozzle. In addition, the nozzle, thus obtained, is characterized by a lack of high specific surface.
In the patent of Russian Federation №95101819 described a method of manufacturing a nozzle including sat the CGS corrugated plates made of inorganic material in the package with mutually crossing directions bumps in the adjacent plates and the binding of these plates in their places of contact, using thermochemical processing in the environment of carbon-containing gas at 800-1200°C.
Such a method of manufacturing the nozzle can increase the area of the active surface of the nozzle, the bonding strength of corrugated plates in the package and performance tips.
A common feature of the proposed method of manufacture is receiving layer regular packing of corrugated elements attached to each other in the package.
The main disadvantage of this method is that for the Assembly of plates in a package, you must create conditions with a very high temperature, which affects a significant increase in energy consumption in the manufacturing process of the nozzle as a whole.
Known RF patent №2138327, which describes the following method of manufacturing the nozzle: the canvas of mnogoelementnykh ceramic fibers impregnated with a binder solution and dried to obtain prepreg, then the fabric is passed into the gap between the toothed rollers at an angle of 90°. Produce cutting the formed corrugated sheet on the workpiece at an angle of 90°. Then the workpiece plates are collected in the package in a cross direction of the corrugation with the simultaneous application of glue in places touch. After which the package material is subjected to final shaping with simultaneous connection of corrugated sheets by heat treatment.
The method allows to get the design of the nozzle of the material on the basis of different types of matrices, expanding technological opportunities while maintaining a relatively high service life.
A common feature of the proposed method of manufacture is that a layer of regular packing of corrugated elements.
The lack similar to the previous version.
There is also known a method of creating a layer of nozzles described in the patent of Russian Federation №2094113, the essence of which is to create a layer nozzle periodic horizontal isosceles angles, spaced peaks up, with the edges of adjacent shelves in some parts of the form with shelves at the top corners of the lower number of cracks.
Preliminary studies have shown that use of the offered tips will allow you to improve the mass transfer characteristics of the devices by 5-12% depending on their size and properties of the system.
In common with the proposed method of manufacture is that set in the apparatus, the horizontal rows of elements.
The disadvantage of this method is to obtain a layer of the nozzle with a low coefficient of mass transfer.
The closest design (prototype) is the device described in the Russian patent for a utility model 67888, publ. 10.11.2007. This is the Wallpaper regular nozzle for mass-transfer apparatus, containing layers nozzles collected from the package corrugated plates, placed the tabs to each other and places of contacts bonded to each other through missed in the holes of the plates rods that serve as the skeleton of the package.
A common feature of the prototype is the presence of corrugated plates fastened together by rods that serve as a frame.
The disadvantage of the prototype is the increased hydraulic resistance.
The closest (prototype) is the method that is described in Russian patent for a utility model 67888, publ. 10.11.2007. This method of making regular packing "Spraypack" for mass-transfer apparatus is that the packing layer is collected from the package corrugated plates, placed the tabs to each other and places of contacts bonded to each other through missed in the holes of the plates rods that serve as the skeleton of the package.
A common feature of the prototype is the use in the manufacture of nozzles corrugated plates fastened together by rods that serve as a frame.
The disadvantage of the prototype is relatively high hydrodynamic resistance of the nozzle obtained by this manufacturing method.
The objective of the invention is to develop a new high-tech and low-overhead method of manufacturing layer is egularly nozzles, providing the nozzle with a small hydraulic resistance, high coefficient of mass transfer and a uniform distribution of phases in the packing layer.
The technical result of the invention consists in the
- reduction of material costs for manufacturing the nozzle;
- reducing the complexity of manufacturing the nozzle;
- obtaining high-efficiency nozzles with high rates of mass transfer and low hydraulic resistance.
Eliminate these drawbacks and achieve the claimed technical result from the implementation of the method of manufacturing a regular packing for heat and mass transfer devices is due to the fact that plastic, metal or fabric tape attached to the rods of the frame (body guards) so as to form a corrugated surface undulations, and the tapes are not bearing elements, so that their thickness can be significantly reduced, in addition, the tape can be made of plastic or chemically and mechanically resistant fabric that will also lead to cost reduction of the metal, and the arrangement of components of a regular extension provides increased surface contact of liquid and gas (vapor) phase, while by increasing the gaps between the components of a regular nozzle decreases its side hydraulic the mechanical resistance.
A distinctive feature of the method of manufacturing a regular packing for mass transfer apparatus is a band-shaped fastening elements nozzles on a frame of metal rods so that the tape took undulating shape, wherein the edge vertices of the underlying tape in contact with the edge of the trench overlying tape. The framework is a set of horizontal rods placed in a checkerboard pattern. Ribbon round the horizontal rows of rods so as to be above the rod above the line and below the rod downstream of the row.
Comparison with presents analogues allows to make a conclusion on the compliance of the claimed invention, the criterion of "novelty".
The essence of the method of manufacturing a regular packing for mass transfer apparatuses is that initially collect a frame of horizontal elements. The frame elements can be made of horizontal metal rods, angles, hollow tubes or wires and braided ropes. The frame elements can be manufactured from non-metallic materials resistant to the environment in which you will apply the proposed cap. The frame members have horizontally staggered. Then the frame is fixed elements of the nozzle in the form of horizontal strips and flat the vertical metal mesh sheets. Mounting is as follows. When attaching ribbon round the rods alternately from two adjacent horizontal rows so that the studs of the upstream row was under the belt, and below - above the ribbon. Tape can be made of metal and plastic or chemically and mechanically resistant fabric. Vertical sheets of metal mesh strung on the rods of the frame and have them between the vertical rows of ribbons.
The proposed method for the manufacture of regular packing and its operation are illustrated by the drawings (figures 1-3).
Figure 1. Fastening tapes and sheets of mesh on the frame.
Figure 2. The nozzle of undulating ribbons.
Figure 3. The scheme of gas and liquid flows on the attachment.
Figure 1-a shows the method of fastening tapes on the rods of the frame (side view), figure 1-b shows the method of fastening sheets of mesh (top view). 2 shows the design of the nozzle. Figure 3 shows a diagram of gas and liquid flows on the attachment.
The nozzle is made of frame elements (1), horizontally mounted metal strips, or plastic strips, or tapes of chemically and mechanically resistant fabric (2) and vertically mounted metal mesh (3).
First assemble the frame of the individual elements of horizontal metal rods, or corners, or hollow tubes or PR is drawing dies, or of braided ropes. Elements together are attached by welding. The frame elements can be manufactured from non-metallic materials that are resistant to the environment in which you will apply the proposed cap. The frame elements have the space horizontally staggered with obtaining a volume grating. Then the frame is fixed elements of the nozzle in the form of horizontal strips and flat vertical metal mesh sheets. When attaching ribbon round the rods alternately from two adjacent horizontal rows so that the studs of the upstream row was under the belt, and below - above the ribbon. Tape can be made of metal and plastic or chemically and mechanically resistant fabric. Vertical sheets of metal mesh strung on the rods of the frame and have them between the vertical rows of ribbons.
Made this way, the nozzle operates as follows. The process of mass transfer occurs when the countercurrent movement of the liquid and vapor phase. Gas (vapor) phase is fed from the bottom layer of the nozzle, and the liquid from above. Contact phases occurs through direct interaction flows, as shown in figure 3. The liquid flows on the specified bands, this increases the contact time of the liquid and vapor phase. Tape installed in the way, that the longitudinal axis of the tape is horizontal, the liquid phase, getting on the tape, onto the two underlying, passing through the vertically mounted metal mesh sheets adjacent to both edges of the tape. The mesh sheets break the flow of the liquid phase, increasing the area of contact of the liquid with the vapor phase.
Thus, when implementing this method of making regular packing bearing capacity is transferred from the elements nozzles directly involved in the process of mass transfer and creates a specific area of the nozzle, on the frame, which enables to produce these items from thin metal strips or plastic, or chemically and mechanically resistant fabric, resulting in a savings of metal and ceramics.
A method of manufacturing a regular packing for mass transfer apparatuses, in which the packing layer is assembled from corrugated strips, vertical metal mesh and frame, characterized in that the first collect a frame of horizontal supporting rods arranged in a checkerboard pattern, then the frame is fixed to the tape so that in the alternate rounding ribbons bearing rods of the frame formed on the tapes of the corrugations, while the edge vertices of the underlying tape in contact with the edge of the trench overlying tape, strung on the rods the slight pressure from the beginning of the flat metal mesh sheets, the vertical mesh sheets fitted between the vertical rows of corrugated ribbons.
