Air supplying device of frozen air with temperature of being more than negative subzero 20 DEG C

Abstract

The invention discloses an air supplying device of frozen air with a temperature of being more than negative subzero 20 DEG C, comprising two groups of filtering systems. The air supplying device is characterized in that two ends of the two groups of the filtering systems are respectively connected through air pipes; each air pipe is respectively provided with a No.1 solenoid valve; one of the two No.1 solenoid valves is connected with a No.2 solenoid valve through an air conveying pipe; and the two groups of the filtering systems are respectively provided with heating plates. According to the air supplying device disclosed by the invention, the filtering systems can be switched at regular time through the No.1 solenoid valves and the No.2 solenoid valves and water is discharged after the air is heated by the heating plates. The air supplying device is low in use cost, is efficient and energy-saving, and is not frozen. Therefore, the un-dehumidified air in a common environment can be directly used and the air does not need to be pre-dried and dehumidified.

Description

technical field [0001] The invention relates to an air supply device, in particular to an air supply device for refrigerated air above minus 20 degrees. Background technique [0002] In the field of low-temperature gas use, the current traditional method is to use a refrigerator to cool the normal-temperature gas to obtain high-temperature gas. The disadvantages are that the refrigerator has a long cooling time, high energy consumption, high equipment investment cost, and cannot move freely after installation. Cryogenic gas cannot be supplied intermittently, and freezing may also occur. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a low-cost, high-efficiency, energy-saving, and non-freezing refrigerated air supply device for refrigerated air above minus 20 degrees. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a refrigerated air ...
