[0002] Activated carbon is a kind of black porous solid carbon, which is produced by crushing, forming or carbonizing and activating coal with uniform coal particles. The main component is carbon, and it contains a small amount of oxygen, hydrogen, sulfur, nitrogen, chlorine and other elements. The specific surface area of activated carbon is 500~1700m 2 / g, has strong adsorption performance, and is an industrial adsorbent with a wide range of uses. Activated carbon regeneration method, activated carbon regeneration is the reactivation of fully adsorbed activated carbon after treatment under certain conditions. Activated carbon is used in environmental protection, industry and civil use. It has been widely used and has achieved considerable results. However, after activated carbon is replaced after adsorption saturation, the use of activated carbon adsorption is a physical process, so high-temperature natural gas can also be used to desorb the impurities in the used activated carbon and make it It restores the original activity to achieve the purpose of repeated use, which has obvious economic benefits. The regenerated activated carbon can still be reused and regenerated continuously. In the technical field, there is a lack of a powdered activated carbon regeneration process based on an activation furnace to activate and regenerate activated carbon, and the existing activation furnace is heated by an external heating system, which consumes a lot of energy. The dust suppression effect is poor
