Integrated method and system of active carbon regeneration and hazardous waste incineration

Abstract

The invention discloses integrated method and system of active carbon regeneration and hazardous waste incineration. The system comprises an active carbon regeneration device and a hazardous waste incineration device. In the method, hazardous wastes are in incineration treatment through a multi-section incinerator formed by a rotary kiln and a secondary combustion chamber, high temperature flue gas generated by incineration is led into a rotary active carbon regenerating furnace to provide energy needed by active carbon regeneration, organic pollutants desorbed in the regeneration process is led into the secondary combustion chamber of an incineration system through a glue gas circulation pipeline to be treated in high temperature, and incineration flue gas carries out heat recovery through a waste heat boiler and is exhausted into the atmosphere after being purified by a flue gas purification system. The invention fully utilizes the high temperature flue gas generated by incineration to provide the energy to waste active carbon regeneration, utilizes steam generated by the waste heat boiler to provide a reducing atmosphere to the regeneration process, also completely solves the normal problem of secondary pollution in the process of active carbon regeneration and lowers the investment running cost. Through the integrated design, an integration system has reasonable and compact connection, adopts mature equipment structure and has better economy.

Description

technical field [0001] The invention relates to a method for harmless and resourceful treatment of solid waste, and more particularly relates to an integrated method and system for incineration of activated carbon regenerated hazardous waste.
