Description

Technical Field

[0001] The utility model relates to the technical field of filter screens for desiccant machines, in particular to an integrated filter screen installation structure for desiccant machines. Background Art

[0002] The adsorption dryer achieves the drying effect through the principle of pressure swing adsorption. Since the air's ability to hold water vapor is inversely proportional to the pressure, a portion of the air after drying is decompressed and expanded to atmospheric pressure. This pressure change makes the expanded air drier, and then it is allowed to flow through the desiccant layer that needs to be regenerated and is not connected to the airflow. The dry regenerated air absorbs the moisture in the desiccant and takes it out of the dryer to achieve the purpose of dehumidification. The adsorption dryer needs to use an integrated filter for filtration. The integrated filter installation structure needs to be optimized to improve the efficiency of disassembly and installation and facilitate maintenance.
