摘　　要：湿式电除尘器能够有效捕集湿法脱硫后烟气中的细颗粒物PM2.5、水雾、重金属汞、SO3、酸雾等多种污染物。湘钢360m^2烧结机全烟气脱硫采用石灰石-石膏+湿式电除尘器技术,2018年6月份投产使用。经过一年多稳定运行和数据测试证明,烟气排放浓度能够小于20mg/Nm^3,为烧结机机头污染物控制技术选择提供参考借鉴。Wet electrostatic precipitator can effectively capture fine particulate matter PM2.5,water mist particle,mercury,SO3 acid mist and other pollutants in the flue gas after wet desulfurization.Limestone-Gypsum FGD+wet electrostatic precipitator used in the all flue gas desulfurization of 360m^2 sintering machines of Xiangtan Iron and Steel company.This engineering put into operation in June 2018.After running for one year,the results of operation and experiment test show that the dust emission concentra-tion is lower than 20 mg/Nm^3.It provides a better reference for sintering machine tail choice of pollutant control technology.
