Description

I. () L4L-iinc uiHocMicH for the volume of compressed air drying using adsorption boosters and can be used in systems for producing compressed air on vehicles operating under 1x in different climatic conditions.

The purpose of the invention is to increase the economy and efficiency of the dehumidifier by reducing the air consumption for adsorbing regeneration, improving the air quality and increasing the reliability of the dehumidifier at negative outdoor temperatures () 1 ().

On top of the cover of the cover 5, place the blow-down capacitor-kOi Tb I), siabzhsnpa casing 11 with sodium () 12 and 13 for the supply and drainage I deplonos gel, which can be panri-, compress air after the compressor, sbix.ioniibie 1 az1) 1 or another coolant, CV (and so on, output pipe 14, one end of the kig () K) 11 is connected to the natro fusion cavity ((and the other in capacity K) and is connected to a check valve 15. Moreover, the outer part of the pipe 14 podssnminena conduit 16 to the capacitance Kosgei I). On the pipe (JBode 16 is placed at the bottom; 1 17. In addition to the bottom line between the casing 11 and the purge tank 10, there is 1 control cable connected to the drain pipe and the pipe 18 is located on the pipe 18.

A dehumidifier, for example, in the compressed air preparation system has a compressor 20, a heat exchanger 21, an air collector 22 and a pressure regulator 23.

The dryer works as follows.

During the period of recharge of the air collector, compressed 1 or chi11 air from compressor 20 flows through nozzle 12 into the cavity between the casing 11 and the purge tank 10, washes 11 () oduv (.1 capacity, goes through the outlet 113 into the heat exchanger 21 in which is cooled to a temperature below the dew point, and through the inlet 2 in the housing I enters the pancinoBo between the housing 1 and the cartridge 6, clearing 1c or condensate particles and yes.

temporarily part of the osuitnogo air from the pipe 16 through the throttle 17. enters the purge tank 10, in which it is heated from the case, washed by the hot air coming from the compressor 20.

When the upper working pressure level is reached in the air collector, the pressure regulator 23 triggers and sends a signal for shutting down the compressor 20 and opening the drain valve 4. As a result, pressure is released in the dryer, removal of condensate accumulated at the bottom of the housing 1 and purging of the cartridge 6 with the adsorbent and filter warm air entering through the pipeline 16 through the choke 17 and the outlet pipe 14. The regenerated air, together with the moisture evaporated from the adsorpep 8 and filter 7, is removed through the drainage valve 1 4 to the atmosphere Yeru.

When the pressure in the air collector 22 decreases to the lower operating level, the pressure regulator 23 is activated and sends a signal to close the drain valve 4 and turn on the compressor 20 to the air supply mode. Further cycles are repeated.

With negative outdoor temperatures, the adjustable valve 19 is set to the open position. At the same time, during the period when the compressor 20 supplies air, part of the air entering from the compressor 20 into the cavity between the casing I 1 and the foduvochny tank 10, through the pipe 18 through the drainage pipe 3 is directed to the heating of the drainage valve 4 and da.1ee through the drain pipe 3. The casing 1 is mixed with a cooled heat exchanger 21 with a primary heat sink (5 cm) and sent for cleaning and drying n the cartridge 6.

In addition, the pipeline 18 from the cavity between the housing 11 and the blow-down capacious 1K) K) is the discharge of condensate, which can periodically accumulate I) the cooling process in this air cavity, especially during the compressor sludge period.

The proposed dehumidifier, which is highly efficient and economical in a wide range of ambient temperatures, as well as reduced air consumption for regeneration and high quality compressed air drying due to the use of preheating regenerating air, improves the reliability and durability of H4V systems and vehicles in general. .
