The difference of gas molecular volume uses that gas purification is dedicated molecular sieve used to cross the saturated vapor filtered out in compressed air, can be easily
By Water Molecular Adsorption in sieve particle, recycle regeneration method come redox molecule sieve, compressed air dew point can be light
Easily reach -40 DEG C, absorption drier is to reach drying effect by " pressure change " (principle of pressure swing adsorption).Due to air
The ability for accommodating steam is inversely proportional with pressure, portion of air (referred to as regeneration gas) decompression expansion after drying to atmospheric pressure,
This pressure change makes expanded air become drier, it is then allowed to flow through the regenerated desiccant layer of the need of access failure air-flow (i.e.
Absorb the drying tower of enough steam), the moisture content in desiccant is sucked out in dry regeneration gas, takes it out drier to reach de-
Wet purpose.Two tower cycle operations are not necessarily to heat source, continuously provide drying compressed air with gas system to user.
But the adsorption tube in the A tower and B tower of existing absorption drier subject in most of the time pressure,
The frequent impact of steam and heat is easy to be crushed by mechanicalness, deteriorates performance of the adsorbent, if what is be passed through is high-temperature gas, meeting
Cause different coefficient of thermal expansions, adsorption tube is caused to cause to deform because of temperature stress or destroy.
