摘要
在烟气粉尘控制中,电除尘器和袋式除尘器各有特点,而新型电-袋除尘器--静电激发袋式除尘器结合了上述两种除尘器的技术优势,利用电场凝并作用,不仅提高了对微细粉尘的除尘效率,还降低了除尘器的运行阻力,延长滤袋使用寿命。通过构建小型静电激发袋式除尘装置,讨论粉尘厚度、气体流量、放电间距以及电晕线曲率半径等不同放电参数对静电激发袋式除尘放电特性的影响,从而确定最佳荷电参数。
Electrostatic precipitation（ESP） and fabric filter are used in collecting flue gas dust, which have their own characteristics. Electrostatic stimulation fabric filtration combines the technical advantages of both ESP and fabric filter, and takes advantages of the coagulation effect of electric field, which not only raises the efficiency for fine particle, but also reduces precipitation running resistance and extends the working life of filter bag. In this paper, a small electrostatic stimulation fabric filtration was constructed to investigate the influence of different discharge parameters such as dust thickness, gas flow rate, discharge distance and corona curvature radius, so as to determine the best discharge parameters.
