Description

Technical Field

[0001] The utility model relates to the technical field related to air dryers, in particular to a heat regeneration adsorption air dryer. Background Art

[0002] Adsorption dryers use the moisture absorption property of adsorbents to reduce the moisture content in compressed air and complete the drying of compressed air. They are widely used in the pharmaceutical industry, food processing, breathing air systems, optical systems, chip production, communication technology, data media, laboratories, microbiological experiments, sea level operations and other fields. However, as the adsorbent absorbs more moisture, the adsorbent becomes saturated and powdery, so a thermal regeneration adsorption air dryer is needed.
