Description

Technical Field

[0001] The utility model relates to the field of activated carbon particle regeneration, in particular to a desorption and conveying system for activated carbon particles. Background Art

[0002] Activated carbon is a highly porous adsorption material with a large specific surface area and adsorption capacity. After the activated carbon is saturated with adsorption, it can be desorbed and regenerated for recycling; therefore, the activated carbon adsorption and desorption system is a technology widely used in environmental governance, industrial production, chemical laboratories and other fields.

[0003] In the process of activated carbon adsorption and desorption, it is necessary to transport the saturated activated carbon from the adsorption bin to the desorption bed. After desorption, it is necessary to transport the desorbed activated carbon back to the adsorption bin; in addition, new activated carbon needs to be supplemented. Most of these transportation links rely on manual labor, and some use pneumatic conveying systems. The manual transportation method has high labor costs, low efficiency, and a large amount of dust will be generated during the transportation process, which affects the physical health of the handling workers; the pneumatic conveying method has certain requirements for the particle size of activated carbon particles. For example, a pneumatic conveying system and method for activated carbon disclosed in Chinese Patent CN107998812B involve high equipment costs, complex structures, and high operating costs.
