Description

The invention relates to the field of air conditioning and can be used to create the required humidity parameters of air in the presence of exhaust gases in industry and transport.

The purpose of the invention is to increase the efficiency of the process of regeneration of the adsorbent.

FIG. 1 shows an air dryer, a longitudinal section in FIG. 2 shows section A-A in FIG. one; in fig. 3 section bb in fig. one; in fig. 4 the placement of the air distributor on the drum shaft} in FIG. 5. - section bb. On fig. four; .on FIG. 6 - the sequence of air treatment.

An air dryer for industrial premises with heat installations contains a rotary drum 3 mounted in the casing 1 on a stationary horizontal shaft 2 divided by partitions 4 into sector cavities 5 filled with an adsorbent, pipes 6 and 7 supplying and discharging the processed air, and pipes 8 and 9 supplying and discharging the purge of air. The air dryer is provided with an air distributor 10 mounted rotatably on shaft 2, air and water chambers 11 and 12, respectively, with nozzles 13 and 14 for supplying and discharging exhaust gases and nozzles 15 and 16 for supplying and discharging cooling water. Air and water to the chambers 11 and 12 cover the upper and lower parts of the casing 1 of the drum 3, the shaft 2 of the drum 3 has channels 17 for purging air, communicated with windows 18, made on the upper half of its surface, and the distributor 10 is installed with the possibility of communication its holes 19 sector cavities 5, located in the upper position, with windows 18. The purge air supply pipe 8 is connected at one end to the processed air exhaust pipe 7, and the other end with sector, 5 bar cavity ana 3 located in the upper position. The surfaces of the casing 1 of the drum 3 and the water chamber 12 have fins 20. The nipple 8 of the purge air supply communicates with the sector cavities 5 of the drum 3 through an additional

 installed in the air chamber 1 1 coil 21.

The air to be treated is supplied by a fan 22.

5 Air and water to chambers 11 and 12 are interconnected through a heat-resistant gasket 23 to reduce heat exchange. Air chamber 11 for reducing heat loss to atmosphere

10 is covered with a heat insulating layer 24. The air dryer works as follows.

The treated air is pumped by the compressor 22 through the pipe 6 into the sector cavity 5 of the drum 3 located in the lower position, where the air is dried, and then it is discharged from the cavity 5 through the pipe 7 to the consumer. To the air chamber 11 through the pipe 13 leads exhaust gases.

The regeneration of the adsorbent of the sector cavities 5 of the drum 3 takes place only when the cavities are located in

25 upper position using heat transferred through the casing 1 by heat and radiation, when heated with exhaust gases, and purge heated air entering through the steam generator 8 through the coil 21 located in the air chamber 11. The rotating drum 3 with the adsorbent rotates around the shaft 2 cyclically through every 90 around the circumference.

The sectoral cavities 5 with the adsorbent, when placed in the upper position, alternately communicate with the atmosphere through the openings 19 of the air distributor 10 and the openings 18 of the shaft 2 when they are combined.

When the drum 3 is cyclically rotated in the sector cavity 5 with the adsorbent successively after regeneration, when they are in the upper position and collapse in the lower position, the air cooled by the water chamber 12 is continuously dried.

Moisture-saturated air from the channels 17 is forced out by blowing dry air heated in the coil 21 through the combined holes 19

the air distributor 10 and the window 18 of the shaft 2 into the atmosphere.

Purging with dry heated air is carried out only in the sector cavity 5 located in the upper position. The process of cooling the sectoral cavities 5, when placed in the lower position, is carried out by supplying water through the nozzle 15 to the finned water chamber 12, in which the sectoral cavities 5 of the cyclically rotating drum 3 are enclosed, and about water from the water chamber 12) : board. When the drum 3 rotates around the stationary shaft 2 cyclically at predetermined time intervals at an angle of 90 °, the air is treated as follows: in the sector cavity 5 located in zone a, the adsorbent is preheated but heated after rotation of the drum 3 around shaft 2 34 "sector cavity 5 moves to the zone. &Amp; where the heating and desorption of the adsorbent continue. Further, the sector cavity 5 after the next rotation of the drum 3 around the axis at an angle of 90 moves to zone b, where pre-cooling of the adsorbent occurs after regeneration, and upon subsequent rotation of the drum 3 through the same angle, the sector cavity 5 moves to the zone r where the final the treatment process is the dehumidification of the air, in which case additional cooling takes place with simultaneous removal of the heat of adsorption. The duration of the air treatment processes carried out in zones a 5 8, B KZ, can be set by changing the cyclic nature of the rotation of the drum 3 per unit of time.
