超净电袋复合除尘技术的研究应用进展
Research and Application Progress of Ultra-Clean Electrostatic-Fabric Integrated Precipitator Technology
摘要
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.关键词
