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 regenerated by using self

–

heating

Feature: adopt twin tower ,one absorbing water under certain pressure while the other one

regenerates by using small part of dried air

（

pressure is little higher than standard air pressure

）

.And they

exchange by turn within one cycle. The three stages are :absorbing

–

regenerating

–

balancing pressure

随着加热时间的延长，

JLAH-type micro heat regenerated adsorption dryer process is shown in Fig compressed air entering

through the IA adsorption tower A, the air is dry. After drying air through the CA reaches the outlet,

wherein a part of the air as the regeneration gas arrive separated from the gas stream prior to the outlet,

the flow control via the RV into the H, the H in the regeneration air is heated, the temperature rise, and

then by OB flowing into the adsorption tower B. The adsorption tower B in the upper half cycle of

adsorption down the water, and then angry away moisture and RB and MF emptying the regeneration

stage, and this is heated. With the extension of the heating time, the temperature of the column B is

rising, after a certain time, H power, reconditioning air cooling, this regeneration stage for cooling. RB off

after a set time, the adsorption tower B starts a step until the pressure balance of the two towers. Boost

requires a certain amount of time, to ensure that the pressure equalization of the two towers, or may

cause the outlet pressure fluctuations. After half cycle, IA closed, while IB Open. After a few seconds delay

RA opens. The adsorption column B is now the start of the drying air, while the adsorption tower A into

the reproduction state. Adsorber B to work half cycle back after the reproduction state, this time for a

period of one cycle.
