Activated carbon microwave regeneration device

Abstract

The invention provides an activated carbon microwave regeneration device which comprises a furnace body arranged on a support. A power mechanism is arranged on the furnace body. The furnace body comprises a furnace wall and a quartz glass furnace located in the furnace wall. A feeding hopper is communicated with the quartz glass furnace, and a plurality of microwave heating devices are arranged outside the furnace wall. An auxiliary heating device is arranged in the quartz glass furnace and is provided with rotating force by the power mechanism. The auxiliary heating device comprises a spiral stirring shaft and a heating pipe coaxially arranged in the spiral stirring shaft. According to the invention, the original aerobic environment is changed into an anaerobic environment, so that the safety coefficient is higher; the carbon yield of the activated carbon is increased to 70% from the original 27%; and the unit energy consumption is greatly reduced, and the cost is saved. An auxiliary heating system is added in the equipment, so that the energy consumption can be effectively controlled. Compared with the traditional regeneration process, energy is saved by more than 50%. The method has better practical feasibility in industrial application.

Description

technical field [0001] The invention relates to a microwave regeneration device for activated carbon. Background technique [0002] Activated carbon regeneration method, activated carbon regeneration is to reactivate the 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 the adsorption saturation of activated carbon is replaced, the use of activated carbon adsorption is a physical process, so high-temperature steam can also be used. The impurities inside are desorbed and restored to their original activity, so as to achieve the purpose of repeated use, which has obvious economic benefits. The purpose of the regenerated activated carbon can still be reused and regenerated continuously. Activated carbon regeneration is the reactivation of fully adsorbed activated carbon after being treated under certain co...
