某电厂烟气超低排放改造研究与应用

Research and Application of Ultra Low Emission Transformation of Flue Gas in a Power Plant

为了减少火电厂污染物排放,保护生态环境,电厂采用SNCR法+臭氧氧化湿法对NOX进行脱除,采用石灰石–石膏法脱硫法对SO2进行脱除,并选用除尘布袋与脱硫塔高效除雾器将烟尘高效净化,采用多炉一塔方式进行脱硫除尘一体化改造,有效减少了污染物排放,满足了国家超低排放要求。

In order to reduce the emission of pollutants from thermal power plants and protect the ecological environment,the power plant adopts SNCR method+ozone oxidation wet method to remove NOX,limestone—gypsum desulfurization method to remove SO2,dust removal bags and desulfurization tower efficient demister are selected to purify dust efficiently,and multi-furnace one-tower desulfurization and dust removal integrated transformation is adopted.Effectively reduce pollutant emissions and meet the national ultra-low emission requirements.
