Description

The invention relates to devices for drying compressed air and can be used in the chemical, engineering and other industries.

The aim of the invention is to increase the efficiency of the installation.

The drawing shows the installation diagram.

A compressed air drying unit includes a compressor 1 pneumatically connected to an ejector 2, a heater 3 installed in front of the adsorbers 4 and 5, a suction manifold 6 interconnected by the ejector 7 and the vortex tube 8, the diaphragm 9 of the vortex tube with the peripheral 10 and axial 11 holes connected to the adsorbers and the cooler 12, the water-oil separator 13 connected by the humid air line 14 to the ejector 2, the dried air line 15 and control valves 16-25.

The device works as follows.

Adsorber 4 is in adsorption mode, adsorber 5 is in regeneration mode. The regenerated compressed air from the adsorber 5 through the open valve 24 (valve 23 is closed) enters the ejector 7, into which the atmospheric air is injected into the receiving chamber. The resulting mixture enters the vortex tube 8, where it is divided into a hot peripheral flow and a cold axial flow, in which droplet and partially vaporous moisture is separated, which is released into the condensate during cooling.

The axial cold flow of the mixture of regenerated air from the axial orifice 11 of the diaphragm 9 is directed through the open valve 22 (valve 21 is closed) to the adsorber 4, where it is dried to a predetermined value. Dry air through valve 18 (valve 17 is closed) enters compressor 1, where it is compressed. Compressed dry air through the ejector 2 through the line 15 dried air enters the consumer.

The hot flow from the peripheral holes 10 of the diaphragm 9 of the vortex tube 8 is directed to the refrigerator 12, where it is cooled (L
