6、H type dryer is uesed to remove water in compressed air with the outlet dew point at -20OC-60 OC( or lower as required ) .本机是根据变压吸附的原理，利用自热（无需外部热源）再生的方法对压缩空气进行吸附干燥的一种除湿净化装置。采用双塔结构，一塔在压力下吸附空气中的水分，另一塔用接近于大气压力的部份干燥空气使吸附塔中的吸附剂再生，经过一定时间，两塔切换，这样就保证了干燥压缩空气的连续供应。每个塔的实际工作过程分为三个阶段：吸附再生 充压。Principle: PSA and r

9、再生空气冷却，此为冷却再生阶段。经过设定的时间后 RB 关闭，吸附塔 B 开始升压直到两塔压力平衡。升压需要一定的时间，以保证两塔压力均衡，否则可能引起出口处压力波动。半个循环周期后，IA 关闭，同时IB 打开。延时几秒钟后 RA 打开。现在吸附塔 B 开始干燥空气，而吸附塔 A 则进入再生状态。吸附塔 B 工作半个周期后重新回到再生状态，这段时间为一个循环周期。JLAH-type micro heat regenerated adsorption dryer process is shown in Fig compressed air entering through the IA adso
