M.cl. V01D §3 / 18 The proposed utility model relates to column mass transfer apparatuses and is intended for wet purification of air from gaseous hazards. A known absorber containing a vertical cylindrical body with an inlet and outlet nozzles for gas, horizontal mass transfer plates, an irrigator and a drip trap / cm.a.s.SSSR II62460, M. cl. V01D 53/18, publ. L985 / The disadvantage of this device is the low efficiency of droplet collection and significant splash absorption, which limits its use. The closest known technical solution in its essence and the achieved effect is an absorber, containing a vertical cylindrical body with an inlet gas inlet, horizontal mass transfer plates, an irrigator and a droplet eliminator in the form of two horizontal partitions, between which droplet sedimentation shells are placed concentrically / cm.a.c.SSSR A 1567254 M.C. V01D 53/18, publ. 1990 / In the known absorber, when the gas flow rate changes, part of the concentric channels between the shells are closed or manually opened using rotary valves, which ensures the required gas velocity along the channels and the separation intensity. However, due to the difficulty in determining the moment when such an adjustment is necessary, the latter is carried out untimely and tentatively, and in the case when there is a frequent change in gas flow, such adjustment is not performed due to the fact that the absorber needs to be stopped and partially disassembled . and aij / o xwM. ;

gas flow rates.

The technical result is achieved as follows: In the inventive absorber containing a vertical cylindrical icopnyc with inlet and outlet nozzles for gas, horizontal mass transfer plates, an irrigator and a droplet eliminator in the form of two horizontal partitions, the mead of which are concentrically arranged drop-settling shells, and a suspended spring is placed on the central shell , the gap between the partitions is provided with at least one additional horizontal partition and a vertically mounted radial a wall forming two chambers, limited by the height of the upper and lower partitions, one of which is connected with the cavity of the central shell, through a window made to the entire height of this chamber, and is equipped with entrance windows into the channels between the shell, amzh, and the second camera is equipped with exit windows of these channels and a central output window made in the upper partition.

Placement of porpia in the central shell, piston suspension on the spring, supply of the gap between the partitions with at least one additional horizontal partition, the oh and the vertical installed radial wall, the formation of two chambers by this wall, are limited by the height of the upper and lower partitions, the communication of one camera with the cavity of the central shell through the window, the implementation of this window to the entire height of the specified chamber, supplying the camera with input windows into the channels between the shells, supplying the second camera with output windows and these channels and a central outlet window made in the upper partition allows automatic maintenance of a constant gas velocity with optimal separation of the liquid, with a variable gas flow rate due to a change in the position of the piston depending on the change in gas pressure.

The absorber contains a vertical cylindrical housing I with an inlet and outlet nozzles 2 and 3 for gas, horizontal mass transfer plates 4 with a nozzle 5, an irrigation device 6 and a droplet eliminator in the form of two horizontal partitions 7 and 8, between which drop-settling shells 9 are concentrically placed.

In the central casing, e 10, a piston 12 is suspended on the bail II. The gap between the partitions 7 and 8 is provided with at least one additional partition 13. The specified gap is also provided with a vertically mounted radial wall 11, which forms two chambers 15 and 16. Chambers 15 and 16 are limited in height by the upper and lower partitions 7 and 8.

The chamber 16 is in communication with the cavity of the central shell 10 through OKHOI7, made to the full height of this chamber, and is equipped with entrance windows 18 into the separation channels between the shells 9.

The camera 15 is equipped with output windows 19 of the channels between the shells 9 and the Central output window 20, made in the upper partition 7.

The partitions 13 are provided with openings 22 and a tray 23 for collecting the separated liquid draining from the shells 9. The trays 23 are connected to the vertical tubes 24. The lower end of the tubes 24 has a j visor 25 for draining the trapped fluid on the wall of the housing I. The lower part of the housing I is equipped with a nozzle 26 after draining contaminated liquid. The upper part of the Central shell 10 is provided with a stop 27.

The absorber works as follows. The irrigating liquid is fed into the absorber and sprayed over the cross section using the sprinkler 6. The liquid wets the nozzle 5 on the upper plate 4 and, falling down, moistens the nozzle 4 on the lower plate 4. Next, the liquid flows into the lower part of the body and through the nozzle 26 is removed from the absorber, Contaminated gas through the pipe 2 enters the housing, passes the perforation of the plates 4, liquefying the nozzle 5, and is cleaned of harmful substances. Next, the gas enters the droplet eliminator through the cavity of the central shell 10, raises the piston 12 with its pressure to establish an equilibrium between the weight of the piston and the gas pressure, and then through the window 17 enters the chamber 16 from where through the windows 18 the baffle 9 is directed to the separation curvilinear channels, where under centrifugal forces precipitate liquid droplets on the walls of the shells 9. The gas purified from the droplet liquid enters the chamber 15 through the outlet windows 19 and through the window 20 of the upper horizontal partition 7 / cm. Fig. 3 / direction tsya through conduit 3 to the consumer.

With an increase in gas flow, the piston 12 rises and opens the window 17 of the central shell to a higher height, therefore, the gas enters the separation not only into the lower channels bounded by the lower partition 8 and the adjacent additional partition 13, but also into the overlying tier of the channels limited by additional partitions 13, With a further increase in gas flow and increasing its pressure, the piston 12 rises to the stop 27, opening all the tiers of the separating channels.

With a decrease in gas flow, the piston 12, under the action of its weight, stretches the spring II and lowers down, closing part of the height of the window 17 and stopping the gas access to the separation in the upper tiers of the separation channels.

Thus, the higher the gas flow rate, the higher the cross-sectional area of the separation channels through which the gas passes with simultaneous separation, and vice versa, the lower the gas flow rate, the lower the cross-sectional area of these channels. It provides

the constancy of the gas velocity along the channels with optimal separation. The liquid trapped on the surface of the shells flows down in the form of a film and through the openings 22 it enters the trays 23, is directed through the vertical tubes 24 to the visor 25 and then flows down the wall of the housing I in the form of a film.

The technical and economic efficiency of the proposed absorber is to improve the quality of dropping up to 15-20 due to automatic adjustment of the living section of the separation channels between the shells depending on the change in gas flow, due to the use of a piston suspended on the spring, which changes its position by using the gas pressure energy height and thereby regulates the bore of the separation channels between the shells.
