Three-in-one device of refrigerated compressed air dryer

Abstract

The invention relates to a three-in-one device of a refrigerated compressed air dryer, which comprises a precooler, an evaporator and a gas-liquid separator, wherein the precooler, the evaporator and the gas-liquid separator are in an integrated structure; a warm moist air inlet and a diffusion cavity are arranged above the precooler; the precooler and the evaporator adopt an integral heat exchanger; the upper part of the heat exchanger is a precooling part while the lower part thereof is an evaporating part; the heat exchanger is provided with a horizontal channel and a vertical channel, thevertical channel is a warm moist air channel, the horizontal channel of the precooling part is a low temperature dry air channel, and the horizontal channel of the evaporating part is a coolant channel; and the gas-liquid separator is arranged at the bottom of the evaporator and comprises a filter screen and a guide baffle cavity, a lateral pipeline is connected with the horizontal channel inlet of the precooling part, and a dry air outlet is arranged at the horizontal channel outlet of the precooling part. The invention has the advantages of reasonable structure, compact space, low production cost, saved installation and maintenance charge, and high drying efficiency.

Description

technical field [0001] The invention relates to the field of air drying equipment, in particular to a refrigerated compressed air dryer integrated with precooling, evaporation and gas-liquid separation. Background technique [0002] Air dryers are used to dry and purify compressed air, so that subsequent compressed air equipment can obtain clean and dry air sources, and are widely used in industrial production. The refrigerated compressed air dryer uses refrigerant heat exchange to cool down the humid compressed air, and the supersaturated water is separated from the air to realize the drying of the air, generally including a precooler, an evaporator and a gas-liquid separator Three main components. [0003] The precooler 200 and evaporator 300 in the prior art generally adopt a shell-and-tube heat exchanger structure, such as figure 1 As shown, the warm and humid air 101 passes from the warm and humid air inlet 201 on one side of the precooler housing 203 into the interio...

AI Technical Summary

Problems solved by technology

[0006] In view of the disadvantages of the above-mentioned existing refrigerated compressed air drier, the precooler, the evaporator and the gas-liquid separator are independent, the structure is complex, the floor space is large, and the work efficiency is low, the applicant provides a reasonable structure and compact space. The three-in-one device of the advanced refrigerated compressed air dryer, thereby reducing manufacturing costs, saving installation and maintenance costs, and effectively improving drying efficiency
