Technical Field

Background
The compressed air adsorption dryer achieves the drying effect through pressure change (pressure swing adsorption principle). Since the capacity of air to contain water vapor is inversely proportional to the pressure, a portion of the air after drying (referred to as regeneration gas) is depressurized and expanded to atmospheric pressure, and this pressure change causes the expanded air to become drier and then to flow through the desiccant bed to be regenerated (i.e., the desiccant tower that has absorbed sufficient water vapor) that is not in the air stream, and the dried regeneration gas aspirates the moisture from the desiccant and carries it out of the dryer for dehumidification. The two towers work circularly, and a heat source is not needed, so that dry compressed air is continuously supplied to a user gas utilization system.
In the prior art, the burner needs to use an adsorption type compressed air dryer to separate combustible gas in air, but the burner mainly depends on the air pressure of the compressed air, and when the compressed air enters a drying tower, the air pressure of the air is reduced due to the enlarged space, so that the drying effect is reduced.
