The invention relates to the annapary design of gas purification processes by the method of absorption to wet dust collection and can be used in chemical and adjacent segments of the surface.

A known distillation column comprising a hull, pb the height of which is placed plates made with a recess fl.

The disadvantage of this column is that the pocket, located behind the threshold, does not contribute to the washing-off of harmful impurities from the cloth of the plate.

Also known absorption apparatus, including the plate, the overflow device in the form of a pocket with a deaf bottom, inside which is installed a drain pipe, the upper end of which is located at the level of the tank, and the bottom - under the deaf bottom, the input and output nozzles of the interacting phases 2.

However, the known apparatus does not provide maintenance of a predetermined level on the plate and reliable erosion of harmful impurities from the web of the plate.

The purpose of the invention is to improve the quality of air purification by improving the flushing of harmful impurities and adjusting a given level on the plate.

This goal is achieved by the fact that in an absorption apparatus, including a body, a plate, an overflow device in the form of a pocket with a deaf bottom, inside which j a drain pipe is installed, the upper end of which is located at the level of the liquid, and the lower end is under the deaf bottom. the output of the interacting phases, the overflow device is equipped with a vertical pipe, the upper end of which is located above the liquid level and the lower one at the bottom of the pocket, and a horizontal pipe connecting the upper end of the drain pipe to the vertical ruboy.

Figure 1 shows the absorption apparatus, a longitudinal section (a drain device is installed inside the housing); in fig. 2 - the same, the drain device is installed outside the housing.

Absorption apparatus includes a housing 1, a plate 2, an overflow device in the form of a pocket with a deaf bottom 3, inside of which a drain pipe 4 is installed, the upper end of which is located at the liquid level 5, a vertical pipe whose upper end is located above the liquid level, and the lower 7 placed at the bottom of the pocket, and a horizontal pipe 8 connecting the upper end}; drain pipe 4c

vertical pipe, pipe 9 input absorbent, the threshold Y. The loading absorbent is withdrawn outside the apparatus (figure 2) through the pipe 11 with the end of the plug 12.

The sludge and part of the absorbent is taken by gravity through pipeline 13 with a limited pass, i.e. the outflow of the absorbent by volume should always be less than the supply of absorbent to the plate 2 through the inlet 9. On pipe 12, it is advisable to install an isolating valve to shut off the pipeline, for example; in case of stopping the supply of absorbent to the plate 2. The excess absorbent from the plate 2 is poured over Pipes 4 and 8 and the vertical pipe due to the message, the level on the plate is reliably ensured by the siphon breaking by means of the pipe 14.

The device works as follows.

Absorbent through pipe 9 is fed to plate 2. Polluted air (gas) is introduced into the apparatus and passes through the holes in the plate into the layer of absorbent.

On the plate 2. on the gas jet or gas bubbles act forces in connection with a given movement of the absorbent and its height of the layer. When the direction of motion of the gas jet and the blister bubbles, the impurities contained in them, as the heaviest ones, change, due to inertia, they reach the contact surface and are absorbed by the absorbent, i.e. on the plates the most effective absorption of impurities takes place. Absorption efficiency is achieved by better flushing and draining of impurities throughout the entire cycle.

Harmful impurities, like most solid ones, merge into the recess (pocket) of the plate 2, then go down the drain pipe and pipes 8 and 4. If the level on the plate 2 starts to decrease when the water supply is reduced or stopped at the nozzle 9, the siphon is broken along the vertical pipe and the water discharge stops. The purity of the absobent on the plate 2 is improved by good washing and draining harmful impurities. When exfoliating the mixture in the pocket, overflow pours the lower layer of inferior quality onto the underlying plate. The purified air is withdrawn from the apparatus.

The advantages of the invention are: simplicity, self-cleaning of the absorbent, the possibility of additives, such as alkalis., To increase the absorption of toxic agents, protection against ionized gases when using nuclear means of attack with a tritium component, ease of movement

absorbent according to the revolving cycle, a wide reflection of the specifics.

Thus, the proposed absorption apparatus provides

reliable air purification, washing away of harmful impurities and regulation of the yadak-and-foot absorbent level on the tarblke.
