The invention relates to devices for the adsorption purification of air and can be used in the chemical industry.

The purpose of the invention is to simplify the design and reduce its size.

FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a section of YYD in FIG. one.

The device comprises a cylindrical body 1, which consists of an inner cylinder 2 connected to the inlet 3 of the cleaned air, the middle cylinder 4 and the outer cylinder 5 connected to the outlet of the 6 cleaned air. The inner cylinder 2 in the sorption zone 7 has windows 8 and is connected to the middle cylinder 4 by means of a diaphragm 9 and a cover 10. The middle cylinder 4 has windows 11 in the sorption zone 7 and is attached to the outer cylinder 5 by means of ribs 12. Section 13 with a sorbent, the cylindrical shells of different diameters are divided into a number of compartments in the longitudinal direction by annular partitions 14 in which the inlet 15 and outlet 16 channels for the regenerating agent are made. The annular partitions 14 are interconnected by clamps 17 and have seals 18 along the outer and inner cylindrical surfaces.

Section 13 with a sorbent are located in the cavity between the inner 2 and middle 4 cylinders of the duct body. This cavity between the inner 2 and middle 4 cylinders of the duct body except for the space occupied by the sorption zone 7, which is located opposite the through holes 8 of the inner cylinder 2, is also the desorption zone 19 at the same time. On the average 4 and outer 5 cylinders of the duct case, nozzles 20 are installed to enter and exit the regenerating agent.

Opposite the fittings 20 in the middle cylinder 4 of the duct body are located the inlet 21 and outlet 22 valves for the passage of the regenerating agent, while between the connectors 20 located on the outer cylinder 5 of the duct case.

and inlet 21 and outlet 22 valves are provided with through-grooves 23 passing through fins 12.

Desorption chambers 24 are located in all those compartments of sections with a sorbent that are outside the sorption zone 7, while each desorption chamber 24 is limited by the volume between the adjacent annular walls 14 and the gap between the inner 2 and middle 4 cylinders of the air inlet duct . The volume of the chamber 24 desorption is equal to the volume of the corresponding compartment of sections 13 with a sorbent.

The mechanism for moving sections with a sorbent consists of a hydraulic or pneumatic cylinder 25 that is hinged to the crown 5 mattes 26, which are fixed in turn rigidly inside the cylinder 2 of the rocker arm 27 fixed to the rod of the hydraulic or pneumatic cylinder of two tons of 28 that are hinged on the one hand to the rocker 27, and on the other - to the extreme annular partition

 14 sections with a sorbent.

Pipelines 29 for supplying oil or air to a hydraulic or pneumatic cylinder 25 have a connection with the outer cylinder 5 of the duct body through the rib 30 of a bone gesture 5.

The device for continuous air cleaning works as follows.

The polluted air, entering through the nozzle of the inlet 3, passes through the inner cavity of the inner cylinder 2 of the case of the air-breather and out through the windows 8 into the sorption zone 7. In the sorption zone 7, the polluted air passes through one of the compartments of the sections 13 with the sorbent, while the impurities in the air are deposited on the sorbent. When air moves from the inner 35 shells of sections 13 with a sorbent to the outer diameter of the shells and the area of air contact with the sorbent increases, the speed of air passing through the sections with the sorbent decreases, and the degree of air purification liquefies.

The cleaned air exits through the windows 11 in the middle cylinder 4 of the duct case 1 into the cavity between the middle 4 and the outer 5 cylinders and then goes to the outlet nozzle 6. While one of the compartments of the sections 13

the sorbent is in the sorption zone 7 and cleans the air from impurities; the remaining compartments are in the desorption zone 19 on one or the other side, or on both sides relative to the sorption zone 7 and are cleaned from impurities, respectively, in the desorption chambers 24.

After saturation of the sorbent, located in the sorption zone 7, the impurities from the purified air under the action of a hydraulic or pneumatic cylinder 25, rocker arm 27 and section 28 of the sorbent 13 are moved in the axial direction to a path equal to the distance between adjacent annular partitions (the stroke stops of the hydraulic or pneumatic cylinder 25 and the hydraulic or pneumatic cylinder control circuit 25 and the hydraulic or pneumatic cylinder control circuit are not shown in the figures), and the contaminated compartment of sections with sorbent 13 falls into the desorption zone 19, and the 7 litter tion takes compartment with purified sorbent.

The contaminated compartments of sections 13 with a sorbent, being in the desorption zone 19, are pressed by annular partitions 14, respectively, inlet 21 and outlet 22 valves, while the openings of the inlet valves 21 are aligned with the inlet channels 15, and the openings of the exhaust valves 22 are aligned with the outlet channels 16, which ensures the passage of the regenerating agent through the contaminated compartments of the sections with sorbent 13 and their cleaning.

Thus, all the compartments of the sections 13 with the sorbent pass through the zone 7 of the sorption, first in one direction and then in the opposite direction.

etc.

Sealing the individual desorption chambers 24 from one another and from the sorption zone 7 is provided by seals 18.
