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.
The adsorbent of absorption drier has adsorbed substantial amounts of moisture in absorption phase, therefore needs, in regeneration stage, to make suction
Moisture discharge (regeneration) in attached dose, adsorbent easily discharges moisture under low pressure, high temperature, therefore has low-grade fever absorption drier, nothing
Hot two kinds of absorption drier, in the regeneration stage of adsorbent, meeting drainage compression air (regeneration gas) out of dry air
To the tower for needing to regenerate, to help adsorbent reactivation, the regeneration gas consumption of low-grade fever absorption drier is the 4- for the treatment of capacity
7%, the regeneration gas consumption without hot absorption drier is the 6-12% for the treatment of capacity.Major defect is：1) during adsorbent reactivation
Waste largely dry compressed air 2) although low-grade fever absorption drier gas consumption amount is low, need heater (no heat
Need not), also waste the energy.
