| 摘 要： | 针对电除尘细颗粒物(PM2.5)排放控制,提出利用电除尘指数指导电除尘本体和电源设计选型技术的原理和方法,并介绍电除尘改造的应用案例.通过优化电除尘指数、采用三相高压电源开展电除尘改造和选型.通过电除尘和脱硫塔除雾器的同步改造,可以实现烟囱出口颗粒物排放浓度低于5 mg/m3,同时,PM2.5 (直径2.5 μm 以下的颗粒物)排放浓度低于2.5 mg/m3.示范工程还表明当电除尘器出口PM10(直径10 μm 以下的颗粒物)排放在6~30 mg/m3时,PM2.5占PM10比例为6%至20%;当PM10排放在5~15 mg/m3时,PM2.5排放可低于2.5 mg/m3. |

| Abstract: | This paper discusses electrostatic precipitation for fine particle emission control. According to the so-called electrostatic precipitator (ESP) index, a novel ESP sizing method is presented for both mechanical and electrical specifications. By using threephase rectifier transformer power sources, ESPs give very high collection for fine particle emission control. The ratio of PM2.5 over PM10 is between 6% and 20%. When PM10 emission is around 5-15 mg/m3, PM2.5 is below 2.5 mg/m3. By upgrading ESP and flue gas desulfurization (FGD), particle emissions can be reduced to below 5 mg/m3, and PM2.5 below 2.5 mg/m3. |
