摘　　要：静电过滤器的净化机理为通过高压放电极化空气中的颗粒物,在电场作用下使带电颗粒物趋向集尘板。将静电过滤器安装在一次回风全空气系统中,利用颗粒物分析仪、大气采样泵、风速测试仪等仪器对室内颗粒物浓度进行实测分析。结果显示,静电过滤器对0.450μm以上粒径颗粒有更好的净化效果。送风速度增大会在一定程度上降低静电过滤器的净化效率。The purification mechanism of the electrostatic filter is to polarize particulate matter in the air by high-voltage discharge,and the charged particulate matter tends to the dust collecting plate under the action of the electric field.The electrostatic filter was installed in a return air all-air system,and particle concentration was measured and analyzed using a particle analyzer,an atmospheric sampling pump,and an air velocity tester.The electrostatic filter has a better purification effect on particles with a particle size of 0.450μm or more.Increasing the speed of the air supply will reduce the purification efficiency of the electrostatic filter to some extent.
