Compressed air drying system and drying method thereof

Abstract

The invention relates to a compressed air drying system and a drying method thereof. The compressed air drying system comprises an outer body provided with a first inner cavity, an inner body arranged in the first inner cavity and provided with a second inner cavity and a discharging part installed on the outer body, the discharging part is at least provided with a discharging cavity communicated with the inner body, a control valve is installed in the discharging cavity, a backflow cavity is formed between the inner body and the outer body, a backflow opening communicated with the backflow cavity is formed in the inner body, the inner body is provided with an air inlet part and a waste airexhaust part, and an adsorbent and a retractable air inlet unit are arranged in the second inner cavity; the air inlet part and the waste air exhaust part respectively comprise an air pipe communicated with the second inner cavity and an electromagnetic valve arranged on the air pipe, the input end of the air inlet unit is communicated with the air pipe, and the air inlet unit can expand when air enters the second inner cavity and is used for enlarging the air outlet surface; the system has the beneficial effects that compressed air can be dried, an adsorbent can be cleaned, and addition of a new adsorbent is completed in the cleaning process.

Description

technical field [0001] The invention relates to the technical field of air drying, in particular to a compressed air drying system and a drying method thereof. Background technique [0002] At present, compressed air refers to air compressed by external force. Since compressed air can be used as a power source and other "identities" to be widely moved, at present, when compressed air is used, it needs to be adsorbed (for example: dry), so that To ensure its use effect, but at present, the drying system of compressed air cannot be self-cleaning. Under long-term use, the internal adsorbent will reduce its adsorption effect due to long-term adsorption of compressed air, which will also affect Its adsorption effect on compressed air. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a compressed air drying system and drying method thereof, aiming at solving the problems arising in the above-ment...
