Shandong Shanlan Environment Group Co., Ltd 
Process Principle：
After pretreatment, the waste gas is passed into the adsorption tower of activated carbon/activated carbon fiber/adsorption resin for adsorption treatment. There exists attractive force on the surface of the adsorbent (intermolecular van der Waals force), and the organic gases are adsorbed on the microporous surface of the adsorbent to purify the gases. Adsorbent desorption using steam on the adsorption bed direct heating, the adsorbent in the adsorbent adsorption of organic components out of the steam out of the steam mixture into the condenser through the condensation of cold water to condense, the condensate into the separation of separation barrel. Desorption stage has part of the steam condensed into water to stay in the adsorption bed, desorption is completed after the need to dry the bed. Drying configuration of a separate drying fan, drying fan inlet set steam heater to heat the fresh air, heated to 60 ℃ or so, through the adsorption tank will be adsorbent bed water drying, after drying the adsorption tank waiting for the next adsorption.
Technical Advantages：
1.high adsorption efficiency, large adsorption capacity, wide range of application;
2.steam or high temperature nitrogen desorption safety, condensation and separation effect;
3.easy maintenance, activated carbon regeneration, can reduce operating costs;
4.PLC automatic control, safe and stable operation; 5.adsorption and recovery is a VOCs treatment technology with positive economic benefits.
Scope of application：
1.Activated carbon adsorption desorption condensation recovery device can be used in petroleum, chemical, printing and dyeing, pharmaceutical, electronics, chemical fiber, semiconductor and other industries.
2.Applicable to the air volume concentration is stable, the components of the organic waste gas is relatively single.
