[0002] The adsorption dryer uses advanced chemical technology. Its principle is to use the difference in volume between water and air molecules to filter out saturated water vapor in the compressed air using a gas purification-specific molecular sieve. The water molecules can be easily adsorbed in the molecular sieve particles, and then the molecular sieve can be restored using a regeneration method. The dew point of the compressed air can easily reach -40°C.

[0003] Chinese utility model patent CN216498474U discloses an adsorption dryer with a cleaning mechanism, including a cleaning mechanism installed inside the adsorption dryer, including a drive assembly, a transmission assembly and a cleaning component, and the cleaning component is slidably connected inside the adsorption dryer. Gas is introduced into the adsorption dryer through an air inlet pipe, and the gas-water separator can filter saturated water vapor in the compressed air in the adsorption dryer. The air filtered by the gas-water separator can be discharged through an exhaust pipe, thereby achieving air drying.
