  • 摘要: 当前,中国以PM2.5为代表的灰霾污染形势依然严峻,采取更为严格的措施进一步降低燃煤电厂等重点大气污染源排放已成必然趋势。湿式电除尘器(WESP)由于具有去除PM2.5等细颗粒物的能力而被越来越多的电厂选用。对上海长兴岛第二发电厂烟气中可过滤颗粒物(FPM)、可凝结颗粒物(CPM)、SO3、液滴等关键指标进行了测试分析。结果表明,在湿式电除尘器停运和运行时,烟囱中总颗粒物(TPM)排放浓度分别为30.31 mg/m3和15.74 mg/m3,FPM排放浓度分别为20.31 mg/m3和6.09 mg/m3,PM2.5排放浓度分别为4.06 mg/m3和2.50 mg/m3,CPM分别占TPM的33%和61%,SO3排放浓度分别为4.51 mg/m3和3.06 mg/m3,液滴排放浓度分别为114 mg/m3和102 mg/m3。测试证明,湿式电除尘器的投运对颗粒物和液滴的去除均有明显效果。
    Abstract: Haze pollution involving PM2.5 is currently a serious problem in China, and the implementation of tougher measures to further reduce emissions from key air pollution sources such as coal-fired power plants has become an inevitable trend. Wet electrostatic precipitator (WESP) technology is being adopted by an increasing number of power plants due to its ability to remove PM2.5 and other fine particulate matter. In this study, key indicators such as filterable particulate matter (FPM), condensable particulate matter (CPM), sulfur trioxide (SO3), and droplets in the flue gas of Shanghai Changxing Island No. 2 Power Plant were measured and analyzed. The results indicated that the emission concentrations of total particulate matter (TPM) were 30.31 mg/m3 and 15.74 mg/m3, FPM were 20.31 mg/m3 and 6.09 mg/m3, PM2.5 were 4.06 mg/m3 and 2.50 mg/m3, SO3 were 4.51 mg/m3 and 3.06 mg/m3, and droplets were 114 mg/m3 and 102 mg/m3 at the stack when the WESP was turned off or on, respectively. Similarly, CPM accounted for 33% and 61% of TPM, respectively. This study demonstrates that the utilization of WESP technology has a significant effect on the removal of particulate matter and droplets.
