摘　　要：火电厂烟气中PM2.5控制技术,目前可分为电除尘和袋式除尘两大类。其中电除尘又分常规电除尘、移动电极电除尘、前置聚并器电除尘、湿式电除尘、低温电除尘等;袋式除尘又分为纯袋式除尘、电-袋复合式除尘、先进的混合式电-袋除尘等。文章对这些技术从捕集机理到应用效果进行了分析探讨,推荐了火电厂应用最合适的控制技术。PM2.5 control technology in flue gas of power plant can be divided as electrical precipitation and bag hose pre- cipitation, thereinto, electrical precipitation is divided as conventional electrical precipitation, removal pole electrical precipitation, wet process electrical precipitation; low temperature electrical precipitation etc.; bag hose precipitation is divided as pure bag hose precipitation, electrical-bag-compound precipitation, advanced composite-electrical-bag precipitation etc. The paper makes analysis and discussion on these technologies from the catching mechanism into application effect and commends the power plant to apply the most appropriate control technology.
