Abstract

The present invention relates to a hazardous rejected material cyclone gasification melting system. It includes a main combustion chamber and a secondary combustion chamber which are communicated mutually. Said main combustion chamber is a cyclone combustion chamber on which are set a hazardous rejected material inlet, an additive/fly ash/combustion-supporting fuel inlet, a combustion-supporting air inlet and a gas auxiliary fuel inlet. On the secondary combustion chamber a secondary air inlet, a slag-discharging pipe and a flue gas outlet are set, and in the front of said flue gas outlet an inertial separator is set. Said invention not only can incinerate the hazardous rejected material, but also can melt the ash slag produced by incinerating hazardous rejected material.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to the incineration treatment technology of hazardous waste. technical background [0002] Hazardous waste refers to waste with hazardous characteristics that is included in the national list of hazardous waste or identified by the national hazard identification standards and identification methods. Hazardous waste has the characteristics of flammability, corrosion, reactivity, toxicity or infectivity. If it is not treated in a reasonable and standardized manner, it will definitely cause great harm. For example, the bacteria and viruses carried by medical waste may be highly infectious, and chemical waste contains a variety of toxic and harmful organic substances, so effective treatment and disposal must be carried out. [0003] At present, my country's hazardous waste mainly comes from industrial production, and the annual production of hazardous waste is about 30...
