摘要: 阐述了中国燃煤电厂烟尘排放要求演变及排放特征,回顾了燃煤电厂电除尘技术发展历程,介绍了电除尘技术应用情况,并对其发展趋势进行了展望。中国从20世纪60年代起开展电除尘技术自主研发以来,通过技术引进,消化吸收、再创新,历经五十多年发展,目前技术水平已跻身世界强国之列。中国燃煤电厂烟气“超低排放”,及其实现“超低排放”的主流技术备受世界瞩目!电除尘器一直是中国燃煤电厂颗粒物控制的主流设备,可达到10mg/m3或5mg/m3的超低排放要求,针对高灰煤(Aar>25%)机组,配合湿法脱硫协同除尘,实现颗粒物排放浓度<5 mg/m3也是可行的。预计未来中国电除尘技术将向节能降耗、协同控制、智能化、标准化、国际化方向发展。

Abstract: The evolution of emission requirements and emission characteristics of dust from coal-fired power plants in China is described, the development history of electrostatic precipitation technology in coal-fired power plant is reviewed, the application of electrostatic precipitation technology is introduced, and its development trend is prospected. Since the independent research of electrostatic precipitation technology began in 1 960 s, China has already became one of the most dominating countries in the world after more than fifty years of development through the technology, digestion, absorption and re-innovation. The Ultra-low dust emission of coal-fired power plant and the main technology to fulfill the Ultra-low emission has attracted worldwide attention. The electrostatic precipitator has always been the main equipment for particle control in coal-fired power plants, which can meet the requirement of ultra-low emissionof 10 mg/m3 or 5 mg/m3. As for the high ash coal (Aar>25%) unit, it is also possible and feasible to realize the concentration of particle emission lower than 5 mg/m3 through cooperating with wet desulfurization and dust precipitation. It is expected that the direction of dust precipitation technology will be energy saving, cooperative control, intelligence, standardization and internationalization in the future.

Key words: coal-fired power plant, energy saving, electrostatic precipitation technology, development and application, trend and outlook
