摘要:

根据燃煤电厂湿法脱硫出口污染物排放浓度及其排放绩效,分析了超低排放湿法脱硫的治霾效果,阐明了湿法脱硫有利于减少SO2、颗粒物、SO3的排放量,这些污染物都是形成雾霾的前体物,表明超低排放湿法脱硫对雾霾治理有积极的贡献。同时,烟气超低排放具有协同治理有色烟羽的能力,对于有色烟羽治理应采取因地制宜的策略。煤电行业广泛开展烟气超低排放改造后,大气污染物排放量持续减少,空气环境质量逐年改善,湿法脱硫、烟气超低排放功不可没。

Abstract:

According to the emission concentration and emission performance of pollutants from wet flue gas desulfurization (WFGD) of coal-fired power plants. The haze control effects of ultra-low emission WFGD were analyzed. Emissions of SO2, particulate matter and SO3 are reduced by WFGD. These pollutants are precursors of haze. It shows that it has positive contribution to haze control by ultra-low emission WFGD. At the same time, the colored plume has been ability to control cooperatively by ultra-low emission. The colored plume should be controlled according to local conditions. After the extensive transformation of ultra-low emission in electricity industry, emissions of air pollutants have been continuously reduced. The quality of air environment has improved year after year. The contribution is due to WFGD and ultra-low emissions.

Key words: coal-fired power plant, wet flue gas desulfurization, ultra-low emission, haze control, colored plume
