      Research and Application Progress of Ultra-Clean Electrostatic-Fabric Integrated Precipitator Technology

      摘要:
      为了实现燃煤电厂的超低排放,在常规电袋复合除尘技术的基础上,突破了电区与袋区的耦合匹配、高均匀流场、高精过滤、微粒凝并等关键技术升级而形成了超净电袋复合除尘技术.超净电袋复合除尘技术具有排放长期稳定、工艺流程简单、煤种适应性广、投资省、占地少、运行费用低、不产生废水等优点.近2年来在燃煤电厂超低排放工程中得到快速推广应用,配套国内燃煤电厂总装机容量超过30 000 MW,其中1 000 MW机组有8台套,排放质量浓度均小于10 mg/m3或5 mg/m3,平均运行阻力663 Pa.超净电袋除尘已成为燃煤机组实现超低排放的主流技术路线之一,将在西部地区劣质煤电厂超低排放改造工程中发挥更大作用
      Abstract:
      To achieve the goal of ultra-low emission for coal-fired power plants,based on the conventional EFIP technology,the ultra-clean electrostatic-fabric integrated precipitator (EFIP) is developed,by upgrading the key technologies such as coupling matching between electrostatic field and fabric area,high uniform flow field distribution,high-precision filtration and particle coalescence technology.Featured by stable long-term emissions,simple technical process,high adaptability to varieties of coal,low investments,less land occupation,low maintenance costs and no waste water production,the ultra-clean EFIP technology has been rapidly popularized and widely used in coal-fired power plant ultra-low emission projects for the recent couple of years,with the total installed capacity of domestic coal-fired power plants over 30 000 MW,including eight 1 000-MW units.The emission concentrations are all below 10 mg/m3 or 5 mg/m3,and the average running resistance is around 663 Pa.The ultra-clean EFIP has become one of the mainstream technical routes to achieve ultra-low emission for coal-fired power plants,and will play an even more important role in the ultra-clean emission renovation projects for power plants burning inferior coals in westem area of China.
