The invention provides a hazardous waste incineration flue gas purification and waste heat utilization system and method. The problems that during existing hazardous waste incineration flue gas treatment, secondary pollution can be generated, and the energy utilization rate is low are solved. The system comprises a flue gas purification unit and a waste heat utilization unit, wherein the flue gas purification unit carries out deep purification treatment on flue gas generated after hazardous waste incineration, and the waste heat utilization unit reuses energy generated by purification treatment. The method comprises a flue gas purification process and a waste heat utilization process. By means of the system and method, deep purification treatment can be conducted on the flue gas generated after hazardous waste incineration, so that emission of harmful substances in the flue gas is effectively reduced, the treated flue gas completely meets the environmental protection requirement, and meanwhile, secondary pollution cannot be generated in the flue gas treatment process. According to the system and method, the hazardous waste incineration flue gas can be discharged after reaching the standard, meanwhile, flue gas waste heat can be used for power generation, so that the energy utilization rate is greatly increased, and resources are saved, and the operation cost is reduced.
Description
technical field [0001] The invention relates to the fields of flue gas purification and flue gas waste heat utilization, in particular to a hazardous waste incineration flue gas purification and waste heat utilization system and method. Background technique [0002] With the continuous acceleration of industrialization and urbanization, the discharge of solid waste is increasing day by day, especially the chemical organic solid waste and medical solid waste discharged from petrochemical, medical, shipbuilding, smelting and other industries are highly corrosive and toxic. If directly Discharge into the environment will cause fatal harm to the human body and cause serious pollution to the environment. [0003] At present, the traditional solid hazardous waste disposal methods are safe landfill, incineration, etc. The purpose of safe landfill method is to cut off the connection between waste and the environment, so that it will no longer cause harm to the environment and human ...
