Description
Technical field
This utility model relates to circular regeneration VOCs treatment, particularly relates at a kind of online circular regeneration organic exhaust gas
Reason method and apparatus.
Background technology
It is the great environmental pollution problem that faces of our province that urban atmosphere haze and ozone exceed standard, and VOCs is that its formation is important
Precursor, VOCs is the most of a great variety, and most poisonous, and part is carcinogenic, seriously pollutes environment and harm human health.With
The fast development of economy, organic exhaust gas (VOCs) pollutes day by day serious, and latent row has a high potential, and advances its improvement to be put into
Country's prevention and control of air pollution major tasks.
The method administering industrial organic exhaust gas at present mainly has absorption process, condensation method, catalysis burning, absorption-absorption method, life
Thing method and plasma method etc..Wherein absorption-absorption process has preferable treatment effect, and can be by high added value after absorption
Separating organic matters reclaim, therefore suffer from the extensive concern of people.
Traditional absorption-recovery process uses many empty materials such as activated carbons as adsorbent, is put into by adsorbent fixing
In Chuan, make Organic substance be adsorbed by bed organic exhaust gas, after utilize hot-air or high-temperature water vapor etc. as desorption be situated between
Matter, by adsorbent bed, makes the high-enriched organics after absorption be desorbed under high temperature action, then through condensation, separation etc.
