The invention relates to apparatus for mass transfer processes in the gas (vapor) - liquid, in particular for absorption and distillation columns.

In the patent of Russian Federation №2094113 described structured packing, which consists of horizontal rows isosceles corner elements arranged with a certain pitch relative to each other. Corner elements each successive row is offset horizontally in such a way as to accommodate between upstream elements, forming a slotted gaps with edges forming the plates of these elements. When the organized flow of liquid and gas phases of the fluid flowing down an inclined shelf area, is supplied to the gap between the edge and shelf downstream of the area and with increased speed due to expire in volume at an angle, effectively contacting decays to jets and dispersive under the influence of counter-current gas flow.

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.

Common features with the proposed design of the nozzles are checkerboard arrangement of nozzles in its cross section and horizontal location in space of the device.

The disadvantages of the top the invention are high hydraulic resistance, low coefficient of mass transfer.

Known nozzle for mass-transfer apparatus according to the patent of Russian Federation №2225753, including horizontal corrugated webs with holes, made of expanded metal sheet located so that the forming of the corrugations of adjacent canvases are mutually perpendicular, and the lower part of corrugations leaf is made blank, no holes. Between the canvases stacked mesh, in which the cut-out window with curved to the upper portions of the corrugations of the underlying fabric sash guides. Deaf part of corrugations or distribution chute is partitioned along the length of the vertical partitions. The edges of the distribution chute is made gear.

The invention allows for uniform distribution of the liquid phase volume of the nozzle, which increases the efficiency of mass transfer.

Common symptoms are known and solutions are available corrugated elements arranged horizontally in the machine.

The lack similar to the previous version.

In the patent of Russian Federation №2226125 described connecting device for mass-transfer apparatus, composed of horizontal rows of inclined rectangular plates arranged at an angle to each other with a gap between the edges, and cracks formed by the plates of the upstream row are against cracks of nigera the prescribed number, between which is placed a horizontal bump, and the bump has a shape of a flat rectangular plate and the width is three times larger than the width of the slit.

The invention allows to intensify the mass transfer process for liquid - liquid by increasing the contact surface phases.

A common feature of the proposed design of the nozzle is the presence of horizontal elements.

The lack similar to the previous version.

Also similar design is the contact device described in patent No. 2209664. In the contact plate is made of a set of direct series. On both surfaces of the plates are made uneven at equal intervals in the row. The adjacent rows are repeated irregularities, opposite one another, and part of the top or deepening of irregularities made a hole connecting the front surface to the rear surface between adjacent rows. On the contact plate in accordance with the present invention, since the holes are made in the transverse direction, perpendicular to the fluid flow, the liquid flows spread not only in longitudinal direction but also in the transverse direction. Since the gas and liquid flows in the transverse direction and they are mixed with each other, the gas flow can also St. is free to move to the front and back surface of the plate.

This contact plate has a high degree of wettability, can improve the efficiency of the gas / liquid contact, has a low weight.

A common feature of the proposed invention is the presence of corrugated strips (sheets).

The disadvantage of this invention is that when a vertical arrangement of the corrugated sheets to the possible mass transfer only in the film mode and the interface is limited by the surface itself of the vertical sheets. Due to bad conditions for the bubble regime, mass transfer efficiency of the nozzle is reduced.

The closest design (prototype) is the device described in the Russian patent for a utility model 67888, publ. 10.11.2007. This device is a regular nozzle for mass transfer devices 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 objective of the invention is to provide a new high-performance regular NASA is key for holding heat and mass transfer processes between gas (vapor) and liquid.

The technical result of the invention consists in:

- increase the efficiency of processes of heat and mass transfer;

- simplifying the structure and reducing the cost of the metal for the manufacture of nozzles;

- reducing the hydraulic resistance of the nozzle.

Eliminate these drawbacks and achieve the claimed technical result from the implementation of regular packing for mass transfer devices containing a framework of rods, horizontal ribbon and vertical grid, is due to the fact that the tapes are mounted on the rods of the frame and 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 between liquid and gas (vapor) phase, while by increasing gaps between the components of a regular nozzle decreases its hydraulic resistance.

The distinguishing feature of the claimed invention is that the metal tape or ribbon, made of chemically and mechanically resistant fabric, mounted on a frame of metal rods so that the tape took a wave-like form, when e is om the edge of the lower base of the overlying tape is flush with the upper edge of the underlying basis.

Unlike the prototype in the inventive regular nozzle installed vertical metal mesh sheets, which increase the surface of the nozzle and increase the efficiency of the process of mass transfer. Tape the nozzle can be made of thin metal, or plastic, or chemically and mechanically resistant fabric and can have the following shapes: flat (figure 1), trapezoidal wave (figure 2) and wavy smoothed (figure 3). Due to the fact that the tapes are attached to the frame (volume grating from metal rods, the thickness of the metal strips may be reduced, which will lead to a reduction of the flow of metal to manufacture in comparison with the conventional nozzles. To improve the efficiency of the mass transfer region of the tape can be performed jagged.

The essence of the proposed regular packing is illustrated in the drawings (figures 1-5).

List of figures:

Figure 1. The attachment of the flat belts.

Figure 2. The nozzle of the trapezoidal wavelike tapes.

Figure 3. The attachment of the smooth wavy ribbons.

Figure 4. The scheme of gas and liquid flows to the nozzle from a flat tape.

Figure 5. The scheme of gas and liquid flows in the nozzle of undulating ribbons.

Figure 1 shows the design of the nozzle of the flat belts. 2 shows the design of the nozzle of the trapezoidal wave tapes. Figure 3 shows the design and the construction of the nozzle of the ripple is smoothed tapes. Figure 4 is a diagram of gas and liquid flows to the nozzle from a flat tape. Figure 5 shows the scheme of gas and liquid flows in the nozzle of undulating ribbons.

The nozzle contains a horizontally mounted metal tape or plastic tape, or strips of chemically and mechanically resistant fabric (1), vertically mounted metal mesh (2) and the frame elements (3). Horizontal ribbon and flat vertical grid mounted on the horizontal frame elements, arranged in a checkerboard pattern, with ribbons have a flat shape, and the vertical mesh sheets have between vertical rows of ribbons. The tape may also have a corrugated shape, a trapezoidal or wavy corrugations.

Offer regular nozzle for mass-transfer apparatus 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 4 and figure 5. The liquid flows on the specified bands, this increases the contact time of the liquid and vapor phase. Tape mounted so 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 with the vapor phase. When using the new nozzle creates more favorable conditions for the process than in the prototype.

Performance tapes may be different, in this case there are three different options: a flat belt (1), belt with trapezoidal wavelike corrugations (4) (2) and tape with smooth wavy corrugations (5) (figure 3). The difference lies in the location of zones of contact between liquid and steam phases, in the case of the use of flat belts a primary contact zone will be a space between the upstream and downstream bands. The liquid phase flowing down from the overlying tape due to the timing of execution of the edges will be evenly distributed, broken down to the stream and dispersive under the action of striving upward gas flow. In the case of the use of tapes with smooth wavy corrugations predominant area of contact of the phases will be the surface of the tape, so as streamlined surface and the contiguous upstream and downstream of the tape will create optimal conditions for the liquid phase flowed from tape to tape, not breaking away from them. In the case of the use of belts with trapezoidal corrugations will not be a preferential zone of contact of phases, however, is that unlike tapes with wavy ribbed belt with trapezoidal corrugations do not have the same streamlined shape, and therefore, the liquid phase will not only flow on the surface of the tape, but also to break the underlying tape. In this regard, the contact between liquid and gas (vapor) phases will occur in the space between the upstream and downstream ribbons, and on the surface of the tape.

A method of manufacturing a nozzle next. First collected frame, the frame elements can be made from metal rods, angles, hollow tubes or wires and braided ropes or other non-metallic element, resistant to the environment in which you will apply the proposed cap. Then on the frame are fixed corrugated ribbon, and a flat metal mesh sheets. Tape can be made of metal and plastic or chemically and mechanically resistant fabric.

Regular nozzle for mass-transfer apparatus, consisting of a horizontally set of corrugated ribbons, vertical flat metal mesh, skeleton, characterized in that the flat vertical grid mounted on the horizontal rods of the frame, arranged in a checkerboard pattern, with vertical mesh sheets have between vertical rows of ribbons, and the lower edge of the base of the overlying tape is flush with the upper edge of the base of the underlying tape.
