Design of Regeneration Process for a Certain Waste Activated Carbon
Taking the advanced regeneration treatment of waste activated carbon in the Green Island Center of a city in Guangdong as an example,this paper elaborates and analyzes the operating principle and characteristics of the waste activated carbon regeneration system,and analyzes the composition of waste activated carbon.This project adopts the process of"bucket elevator+chute+multi hearth furnace+secondary combustion chamber+waste heat boiler+quench tower+dry deacidification tower+bag filter+two-stage wet scrubbing tower+induced draft fan+SGH+stack".The paper introduces the detailed process flow and parameters of the whole process from pre-treatment to regeneration system,and then to gas handling system in detail,and summarizes relevant design experience.It has been proved that the use of decentralized adsorption-centralized regeneration can economically and effectively achieve large-scale regeneration of waste activated carbon.
