SU1607891A1 - Moisture separator - Google Patents

Abstract

The invention relates to air treatment devices for pneumatic instrument power systems and allows for simplified construction. Air for cleaning and dehumidification enters the lower chamber of the housing under the filter along the inlet line. Passing through the filter sponge layer, the air leaves moisture in it and passes into the upper chamber and further along the output line to the consumer. The sponge is cleaned due to the pressure drop on it due to the operation of the control unit. 2 Il.

Description

The invention relates to air treatment devices for pneumatic instrument power systems and can be used in any industry where air cleaning and decontamination are necessary.

The aim of the invention is to simplify the design while maintaining efficient regeneration of the filter element.

FIG. 1 shows a dehumidifier general view; in fig. 2 - the same, at the time of regeneration of the filter element.

The dehumidifier contains a housing 1 with an inlet 2 and an outlet 3 with nozzles, filtering ele- ment 4 of elastic material that is enclosed between two fixed grilles 5 and 6, a drain nozzle 7. An input line 8 with a valve 9 is connected to nozzle 2, - output line 10 with valve 11, to nozzle 7 - drain line 12 with valve 13. The housing cavity above and below the filter element is connected by lines 14 and 15 through differential pressure gauge 16 to control unit 17, which is connected to valves by pulse lines 18-20 respectively 9, 11 and 13.

A dehumidifier works in their own way.

The air for purification and intake is supplied to the lower chambers 2 of the housing 1 through the inlet line 8. The passage through the layer of the filter element 4, the AIR in it is moisture and passes into the upper chamber 22 of the housing 1 and further through the valve 11 along output line 10 to the consumer. As accumulation in the filter element sponge increases, the pressure differential increases in the lower chamber than in the upper chamber, and this value is proportional to the moisture content of the sponge, at a certain value of which differential gauge 16 outputs a signal to control unit 17, which produces an automatic line re-switching - closes valves 9 and 11 and opens valve 13. In doing so, the air, acting on the sponge, squeezes out the water accumulated in it (Fig. 2). As water is squeezed out of the sponge, the pressure drop

the sloth between the upper and lower chambers is balanced. Then the control unit 17 opens the valves 9 and 11 and closes the valve 13 - the air again begins to flow to the consumer.

As the tests showed, the sponge with a thickness of 50 mm and a diameter of 0.5 m works well for 6 months, after which, due to the accumulation of oil and mechanical microparticles, it must be changed.
