The invention relates to instrumentation of gas cleaning processes by adsorption.

The aim of the invention is to stabilize the operation of the adsorber at variable gas loads.

The drawing shows the adsorber, a longitudinal section.

The adsorber includes a housing of a rectangular cross section in which frames with grids 2 are installed, between which adsorbent 3 is poured, are formed into layers. In the gas passage cavity, inclined partition walls 4 in the form of a wedge are installed, which divide the cavities into tapering channels 5 along the gas flow. These channels are divided into sections by vertical partition walls 6 with valves 7 of elastic material. The number of valves depends on the speed range of the gases to be cleaned and the windows 8. Above the frames with grids are installed 9 dl nozzles. supply of regenerating agent. The adsorber is also provided with manholes 10 for loading and unloading the adsorbent, pipes 1-1 and 1 for introducing and withdrawing gas, pipe 13 for withdrawing the regenerating liquid. The adsorber works as follows.

The multicomponent gas mixture enters the adsorber body 1 through pipe 11 and is distributed between the constricting channels 5. As the protrusions pass through these channels, the gas flow decreases, but due to their constriction, the gas velocity remains constant the entire surface of the adsorbent, in the layers of which the gas mixture is purified or separated. The purified gas is removed from the apparatus through the nozzle 12.

At low gas loads, the first ones are included in the course of gas flow.

Adsorber sections. When the gas load increases, the valves 7 of elastic material under the action of the gas flow open and the remaining sections of the adsorber are activated. Thus, the effective use of the adsorber layer is ensured, while the absence of elastic valves with variable gas loads would lead to unstable operation of the apparatus , to the irrational use of the adsorber.

With the accumulation of harmful impurities on the surface of the adsorbent, it is regenerated by means of nozzles 9, through which the liquid for regeneration is supplied. The regenerate is removed from the apparatus through the nozzle 13.
