Abstract

The invention relates to an activated carbon regeneration device and method. The activated carbon regeneration device comprises a storage and feeding system, a carbonization and desorption system and an activation and reaming system. A carrier gas pretreater, a carrier gas blowing device, a carrier gas distributor, an activated gas pretreater, an activated gas controller and an activated gas fluidizer are added before carbonization desorption carrier gas and high-temperature activated chambering activated gas enter a reactor, so that the carrier gas and the activated gas are uniformly distributed in the reactor, passive secondary adsorption of activated carbon is avoided, and the utilization efficiency of activation gas and the activation efficiency of activated carbon are improved. Besides, the device is not provided with mechanical rotating equipment, so that the mechanical damage to the activated carbon is small. The problems of high energy consumption, economic and resource waste and serious environmental pollution in the waste activated carbon treatment process can be solved and relieved.

Description

technical field [0001] The invention relates to the technical field of waste activated carbon regeneration, in particular to an activated carbon regeneration device and method. Background technique [0002] my country is a major producer of activated carbon, and the output of activated carbon accounts for about 1 / 3 of the world's total output of activated carbon. In 2019, my country's activated carbon production capacity is 1.2 million tons, including 301,000 tons of wood-based activated carbon and 574,000 tons of coal-based activated carbon. From 2016 to 2021 The average annual growth rate of the main purpose of my country's activated carbon industry is 4.9%-6.3%. According to reports, at this stage, my country's annual hazardous waste production is 80 million tons per year, of which waste activated carbon accounts for 65%. At present, waste activated carbon is mainly used as admixture in coal-fired boilers for incineration, and has not been recycled for secondary use. Due...
