摘要/Abstract

摘要： 为了验证立式方筒静电脱雾除尘器对微细粉尘的净化效果，按照工程实际应用要求的规格尺寸，组建了一套单筒脱雾除尘器试验测试系统.在实验系统上分别测试了电场风速、极间电压、电场长度、粉尘质量浓度等因素对模拟烟气中微细粉尘的除尘效果的影响.测试结果表明，在电场风速为2.6m·s^-1，极间电压60kV，电场长度6m条件下，立式方筒静电脱雾除尘器对烟气中质量浓度低至50mg·m^-3的粉尘表现出96.66%的除尘效率;并且，对粒径≤2μm的粉尘颗粒仍然具有93%的除尘效率.

关键词: 微细粉尘, 电场长度, 粒度分布, 净化效率

Abstract: In order to verify removal performance of superfine dust in the vertically quadrate wet electrostatic precipitation(WESP)， a WESP test system was set up in accordance with the practical engineering application requirements. In the experimental system， the influence of factors on the dust removing effect were tested such as the wind speed， the voltage between the electrodes， the electric field length and the dust concentration of fine dust in the simulated flue gas. The test results showed that when wind speed was 2.6m·s^-1， voltage was up to 60kV， field length was 6m and dust concentration of fine dust in the simulated flue gas was low to 50mg·m^-3， the dust removal efficiency in the vertically quadrate electrostatic precipitation dust showed high to 96.66%; also， the removal efficiency of dust particle whose diameter was equal to or less than 2μm still achieved 93%.

Key words: superfine dust, electric field length, particle size distribution, removal efficiency
