The treatment process of copper-containing waste recycling flue gas purification

Abstract

The invention belongs to the technical field of flue gas and waste gas purification and treatment, and in particular relates to a treatment process for copper-containing waste recycling and utilization of flue gas purification, comprising the following steps: flue gas purification in a drying process; Acid + jet activated carbon + bag dust removal + induced draft fan + chimney"; flue gas purification in roasting process: flue gas purification process route is "gravity sedimentation + slaked lime dry deacidification + bag dust removal + induced draft fan + RTO + SCR denitration synergistic catalyst to remove two Oxygen + GGH plate heat exchanger + limestone-gypsum wet deacidification + booster fan + chimney"; smelting process flue gas purification: flue gas purification process route is "gravity sedimentation + surface cooling + slaked lime dry deacidification + cloth bag Dust removal + induced draft fan + RTO + catalyst reaction tower for dioxin removal + limestone-gypsum wet deacidification + booster fan + chimney"; the process of the invention achieves the purpose of reforming safety, environmental protection, energy saving and emission reduction, and has the advantages of improving the local ecological environment. important meaning.

Description

technical field [0001] The invention belongs to the technical field of purification and treatment of flue gas and waste gas, and particularly relates to a treatment process for recycling copper-containing wastes by utilizing flue gas purification. Background technique [0002] The industry in Wuxi is developed, and there are many electroplating and electronic industry enterprises, wire and cable enterprises, and a large amount of industrial sludge is produced. The sludge of electroplating and electronic industry enterprises contains a variety of harmful heavy metals with complex components, involving many types of hazardous substances defined in the "National List of Hazardous Wastes". The hazardous properties are toxic, which is a typical industrial solid hazardous waste. Heavy metals such as copper in sludge migrate along the path of "sludge → soil → crops → human body" under the action of rainwater leaching, endangering human health through the biological chain, and may c...
