It suits especially for light concentration VOCs(volatile organic compounds) which are not appropriate to be adsorbed or burned directly, and it would be the best choice for large airflow situation. The treat system and equipment is widely adopted in all kinds of workplaces with poisonous VOCs discharges , such as in paint spraying plant, rubber factory , printery etc.
How does the system work?
Adsorption, desorption and catalytic combustion are the main steps.
Firstly, the big particles are filtered by the primary filter. It helps to protect the activated carbon from abrasion and have a longer service life.
Then, the activated carbon works. The VOCs are adsorbed to the millipores of the activated carbon, and the purified air will be discharged. Honeycomb structure (of the activated carbon) has extremely large surface with powerful adsorption. When the activated carbon filter is nearly fully laden, it's time for desorption. The VOCs get away from the activated carbon under the action of heat and catalytically combust. Only water(H2O) and carbon dioxide(CO2) which are safe to discharge, are produced in the combustion. The heat generated in the combustion can be used in the next turn of desorption and catalytic combustion.
