微热吸附式干燥机

微热再生吸附式干燥机特点

根据变压变温吸附（PSA.TSA)原理，利用吸附剂本身对水蒸汽特有

的亲和力，吸附压缩空气中的水分。本设备制成双塔结构，在程序控制

器（PLC)的控制下.两塔交替工作.一塔在较离的压力下吸附水分，

另一塔在较低压力、较离温度下利用本身制备的干空气来完成水汽的脱

附过程，连续循环地工作。设备气耗量小于无热再生吸干机.但需消耗

—部分电能用以加热再生气。

Externally heated purge desiccant compress air dryer

According to the principal of PSA and TSA.the moisture in thedir willbe adsorbed

and compressed with the special appetency of the sorbent on the steam

madchirne is of two-tower structure.Under the control of PLC.the two towers will run

altdfnately.Ond lower adsorb the moisture under high pressuce and another tower

complete the desorption of steam with the dry air produced by itsetf under low

pressure and high temperature,thus keeping runniog circularly.The air

consumption of themachine is lower than the heattess regenefative dryef.but

some electric power should be consumed to heat theregelated air.
