Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon regeneration devices, in particular to an activated carbon recovery and regeneration device. Background Art

[0002] Activated carbon is a specially treated carbon. The organic raw materials (fruit shells, coal, wood, etc.) are heated under air-tight conditions to reduce non-carbon components (this process is called carbonization), and then react with gases, the surface is eroded, and a structure with developed micropores is produced (this process is called activation). Since the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point erosion, the surface of the activated carbon has countless tiny pores, which play an adsorption role. After the service life of the activated carbon ends, it becomes waste activated carbon. The recycling and regeneration of activated carbon is the reverse process of activated carbon adsorption. It is an operating process in which the recycled and regenerated device is used to precipitate the adsorbed components from the saturated activated carbon so that the activated carbon can be regenerated. High-temperature regeneration is one of the main means of recycling and regenerating activated carbon.

[0003] Most of the activated carbon recovery and regeneration devices currently in use place the activated carbon on a conveyor belt. The conveyor belt passes through the activation heating equipment, and the activated carbon is heated as the conveyor belt moves. However, the activated carbon contains dust. After the powdered activated carbon is heated, the liquid contained in the activated carbon expands and vaporizes. The vaporized steam will carry the activated carbon and splash out to the outside. The splashed activated carbon forms flying activated carbon dust. After the activated carbon dust overflows the heating equipment, it will injure the operator's body and pollute the working environment. Utility Model Content
