Answer: The regenerative adsorption dryer consists of two double-connected barrels filled with desiccant (the surface of the desiccant can absorb moisture). The two barrels turn on and off the airflow, alternately drying and regenerating, so that the airflow can continue to contact the dry desiccant to achieve the purpose of dehumidification and drying. At a certain temperature, the amount of water adsorbed increases with the increase of the water vapor pressure in the air. At a certain pressure, the amount of water adsorbed decreases with the increase of temperature; that is, water is adsorbed at low temperature or high pressure, and water is desorbed at high temperature or low pressure. The dryer works on this principle.
