摘要
应用类似于Williams求声凝并系数的方法导出异性荷电粉尘在交变电场中的凝并系数,根据关于粉尘凝并过程趋于“自保分布”的概念,建立了多分散性粉尘粒度分布随凝并时间变化的函数式,异性荷电粉尘在交变电场中的凝并实验结果表明,新型双区电凝并除尘装置的除尘效率不仅高于电除尘器,而且优于三区电凝并除尘装置.
Formula to calculate the bipolar charged particles coagulation coefficient in a\|c field is derived by using the same method that was developed by Williams for evaluating the acoustic coagulation coefficient. According to the concept of the self\|preserving particle size distribution, the coagulated particle size distribution function is established. The electrostatic collection efficiency of the coagulated particles is higher than that of the particles without coagulation.
