摘要
Abstract
People pay more and more attention on the fine particle pollution in the air with the improvement of environmental protection consciousness. Coal-fired power plant is one of the fine particle pollution sources. The difference of fine particle removal from different precipitators was confirmed by testing the PM10 and PM2.5 mass concentration in the outlet of bag filter, electrostatic-fabric integrated precipitator and electrostatic precipitator in coal-fired power plants. The attention on classification efficiency of dust removal should be enhanced to choose the appropriate precipitator. Fine particles in outlet gas such as PM1.0, PM10 and PM2.5 were collected by cascade low pressure impactor. The test results show that the order of PM10 and PM2.5 removal efficiency from high to low is electrostatic-fabric integrated precipitator, bag filter, and electrostatic precipitator. The order of the dust removal efficiency from high to low is the same as above. The proportion of the fine particle in the electrostatic precipitator outlet dust is lower relatively.关键词
