In the process of production, storage and transportation of dyes, pharmaceuticals, coatings, plastics, chemical fibers, and many petrochemical products and coking products, a large amount of organic waste gas will be generated, which not only causes serious pollution to the environment, but also wastes many valuable resources. The treatment technology of organic waste gas can be divided into two categories, one is the purification treatment technology represented by incineration and catalytic combustion, and the other is the recycling technology represented by adsorption recovery.

The internal structure design of the activated carbon device is reasonable, the gas distribution is uniform, the gas resistance is small, the activated carbon filling is small, compared with the imported similar products, the device has low cost, small footprint, convenient installation and maintenance, reliable operation, and can meet the needs of most waste gas treatment.
