[0002] Bag filter can be used in the field of activated carbon thermal regeneration. Activated carbon regeneration method: activated carbon regeneration is to reactivate fully adsorbed activated carbon after being treated under certain conditions. Activated carbon has been widely used in environmental protection, industry and civil use, and has achieved considerable results. However, after activated carbon is replaced after adsorption saturation, the use of activated carbon adsorption is a physical process. Therefore, high-temperature steam can be used to desorb impurities in the used activated carbon and restore its original activity to achieve the purpose of reuse, which has obvious economic benefits. The regenerated activated carbon can still be reused and regenerated continuously. Activated carbon regeneration is to reactivate fully adsorbed activated carbon after being treated under certain conditions.
