湿式电除尘对PM2.5/SO3酸雾脱除特性的试验研究
Experimental study on removal properties of PM2.5 and sulfuric acid mist by wet electrostatic precipitator
摘要
Abstract
The removal of PM2.5 and sulfuric acid mist by wet electrostatic precipitator was investiga-ted based on the actual coal-fired experimental platform.The particle size distribution of PM2.5 and sulfuric acid mist at the wet electrostatic precipitator inlet was analyzed.The influences of the volt-age,temperature and inlet concentration on the removal properties of PM2.5 and sulfuric acid mist were studied.The results show that the dust and the sulfuric acid mist are mainly submicron particles at the wet electrostatic precipitator inlet.The growth of the removal efficiency of different sizes is not the same.The removal of PM2.5 and sulfuric acid mist for wet electrostatic precipitator gives pri-ority to larger particles.Reducing gas temperature is helpful to make particles grow up by heteroge-neous condensation and coagulation under the same conditions.The removal efficiency of sulfuric acid mist by wet electrostatic precipitator maintains 30% to 60% on the whole.Thus,the sulfuric acid mist can help improve the removal efficiency of fine particles by wet electrostatic precipitator.关键词
