大气中的PM2.5颗粒对人体健康有长期的不利影响,越来越受到关注。火电厂PM2.5颗粒排放占全社会总量的10%。袋式除尘器能捕捉大多数PM2.5颗粒,高效静电除尘器如选用合适的电源和比集尘面积也能大大提高PM2.5颗粒的捕捉能力。实验室测试表明2种除尘器对PM2.5的捕捉率都可达到90%。除了采用高效除尘器外,降低电厂NOx和SO2的排放也是火电厂减少PM2.5颗粒排放的有效和必要措施。
PM2.5 particles in the atmosphere on human health have long-term adverse effects, more and more attention. PM2.5 thermal power plant particulate emissions accounted for 10% of the total social. Bag filter can capture most PM2.5 particles, high-performance electrostatic precipitator, such as the use of appropriate power and dust collection area can also greatly improve the PM2.5 particle capture capability. Laboratory tests show that both types of dust catcher can capture PM2.5 up to 90%. In addition to using high-efficiency dust collector, the reduction of power plant NOx and SO2 emission is also an effective and necessary measure to reduce PM2.5 particle emission from thermal power plant.
