Songyang XX Industrial Hazardous Waste Comprehensive Utilization and Disposal Project

Songyang XX Industrial Hazardous Waste Comprehensive Utilization and Disposal Project

Flue Gas Treatment Scope: Desulfurization, Removal of NOx, Dust, Hydrogen Chloride (HCl), and Hydrofluoric Acid (HF)

Flue Gas Treatment Method: Limestone-Gypsum Desulfurization, SCR Denitrification, Wet Defluorination, Baghouse Dust Collection, Wet Electrostatic Precipitator (WESP)

Furnace Type: Rotary Kiln and Alloy Furnace

Process Flow: Rotary Kiln Flue Gas: Rotary Kiln Flue Gas: Surface Cooler → Baghouse Dust Collection → Induced Draft Fan → Dry Sorbent Injection (DSI) and Activated Carbon Injection → Baghouse Dust Collection → Induced Draft Fan → Deacidification Tower → Demisting Tower → Heat Exchanger → Denitrification Reactor → Heat Exchanger → Stack Emission Alloy Furnace Flue Gas: Secondary Combustion Chamber → Waste Heat Boiler (with SNCR Denitrification) → Surface Cooler → Baghouse Dust Collection → Induced Draft Fan → Deacidification Tower (treated together with rotary kiln flue gas)
