摘　　要：为了改善环境空气质量,大气污染物治理标准越来越严格是大势所趋,随着我国火电厂超低排放政策的颁布,湿式电除尘技术在火电厂得到大量的运用。通过对国内十多台机组湿式电除尘器运行的现场测试,分析了湿式电除尘器对低浓度污染物的脱除效率。测试结果显示:湿式电除尘器对颗粒物的脱除效率在56.1%~86.4%之间,对浆液滴的脱除效率在59.9%~87.7%之间,对SO_3的脱除效率在60.0%~78.7%之间,结果表明,湿式除尘器对对污染物实现超低排放起着非常重要的作用。To improve the environmental atmosphere quality,therefore,gradually strictly Standards of Air pollution control represented the general trend. With the publish of emission standards of thermal power plant flue gas abatement,Wet electrostatic precipitator（ WESP） has been widely used in heat-engine plant. Through about 10 WESP insitu test in interiorly,the effixiency of low conxentration pollutants by WESP are researched.The results shows that the removal efficiencybetween 59. 9% ~ 87. 7% for droplet quantity and 60. 0% ~ 78. 7%for SO3. The results shows that WESP play an important role in actualize ultra low emission of pollutant.
