Background technology
Absorption drier is to reach drying effect by " pressure change " (principle of pressure swing adsorption).Because air accommodates
The ability of steam is inversely proportional with pressure, and its dried portion of air (being referred to as regeneration gas) puffing is this to atmospheric pressure
Pressure change makes expanded air become drier, then allows it to flow through the desiccant layer of the need of access failure air-flow regeneration and (has inhaled
Receive the drying tower of enough steam), dry regeneration gas suctions out the moisture content in drier, takes it out drier to reach dehumidification
Purpose.Two tower circulation works, without thermal source, continuously provide drying compressed air with gas system to user.
Low-grade fever absorption drier, adsorbent reactivation stage are divided into two parts, and Part I is thermal regeneration --- regeneration
Gas (air for the drying that absorption finishes is derived from outlet pipe) is heated to 100 DEG C or so entrance by regenerating pipeline into heater
Adsorbent reactivation is carried out in adsorption tower, at this moment adsorbent is also heated to high temperature by high-temperature gas, because adsorbent is in the feelings of high temperature
There is no suction-operated under condition, therefore need Part II to blow the cold stage --- at this moment heater is stopped, (50 DEG C of regeneration gas temperature
Left and right) enter regenerator in high temperature adsorbent blow it is cold, cooling, to reach absorption requirement.Major defect is：1)
It is high (50 DEG C) to blow cold gas temperature, it is low to blow cold effect, therefore need to waste a large amount of gases and blow cold, low-grade fever absorption drier regeneration gas
