Description

technical field [0001] The invention belongs to the technical field of air drying, in particular to a compressed air dryer based on vortex tube refrigeration technology. [0002] Gas drying device and its working method. Background technique [0003] Compressed air is the second largest power source next to electricity, and it is also a process gas source with multiple uses. Its application scope covers petroleum, chemical industry, metallurgy, electric power, machinery, electronics, food, medicine, national defense and other industries and departments. . As the wet air is compressed and condensed, it becomes wet-saturated air and entrains a large amount of liquid water droplets, which causes corrosion of equipment, pipes and valves, and freezes in winter to block the small holes in the pneumatic system, which adversely affects the production process and causes huge losses to the national economy. . In order to ensure the dry environment required in such low-humidity indu...

AI Technical Summary

Problems solved by technology

[0004] However, in the prior art, for places that only need deep dry air at atmospheric pressure, the compressed air at the outlet of the high-pressure dehumidifier is directly throttled, resulting in a great waste of air potential energy. The drying device in the traditional technology has a complex structure and low work efficiency
