Description

It is known to use liquid sorbents in air conditioning systems with spray chambers or with chambers having a spray nozzle.

However, at low flow rates of the liquid sorbent, nozzle chambers and irrigated nozzles (for example, such as Raschig rings) do not provide a stable, developed contact surface with dried air.

The described air dryer with the use of an adsorber, a solvent distributor, a collector and a fan, makes it possible to more use the absorptive capacity of a liquid sorbent for drying air, to obtain a developed contact surface with dried air at low costs (5-10 kg / hour) of sorbent and to ensure the possibility of drying the air at a speed of movement of doZ m / sec without separating their devices. The adsorber to the air pump of the stopper is equipped with a distributor with slotted tubes covered with fine capillary with a cloth for uniform wetting, and provided with sheets of finely capillary tissue to provide agitation, a liquid sorbent in the form of a film.

FIG. 1 schematically shows an air drier; in fig. 2- distributor air dryer.

The air dryer consists of the adsorber /, the distributor 2, the tank 3 for the solution, the collector 4 for the solution, the fan 5, the solution pipe 6, the compact pump 7. The adsorber / is a vertical chamber in which canvases of finely capillary material (glass fiber, Marly, etc.). Solution distributor 2 is made in the form of a collector 9 with tubes W of small diameter (15-20 mm), having a narrow slot //, fittings 12

and plugs ii. / Hh р rpvdomernogo smachnvapi liquid tube copoeiiiON 0 (K / covered) with a cannular cloth 14. Humid air from SacM) Fat through the lower part of the adsorber and pass through the bottom of the web x.

The liquid sorbent leaves the slots of the tubes 10, enters the webs 8. Under the action of capillary forces, the liquid sorbent is evenly distributed throughout the webs 8 and slowly flows down.

Cloths from fine-capillary tissue, retaining the sorbent in a stream of dried air, ensure the complete use of the absorbent capacity of the sorbent. Drained air exits the top of the air dryer.

The diluted solution accumulates in the solutionosorpic 4. The solution is circulated through the solution container 4, tank, adsorber (carried out) by a compact pump unit 7 (manually or electrically driven). Thus, o6pa30N, a liquid sorbent in the air dryer, and the air to be purified are flowed countercurrently.

Regeneration of the liquid sorbent is performed routinely. way: evaporation. m or by adding solid salt.

Subject invention

A liquid sorbeptome air dryer, which includes an adsorber, a solvent distributor, a collector, and a fan, differing in that, in order to make better use of the desiccant capacity of the liquid sorbent for air drying, the adsorber is equipped with a slotted pipe distributor. tissue for uniform wetting, and provided with fine capillary cloths to allow the transfer of the liquid sorbent in the form of a film.
