摘要
根据碰撞理论，推导出偶极行电尘粒在突变电场中的电凝并系数，并利用Williams求声凝并的方法，将其简化。电凝并除烟实验在2，4，6Hz三种频率下进行，结果表明：三种频率下的除尘效率比较接近，但频率为6Hz时除尘效果较好。
Based on the collision theory,the electric coagulation coefficient of bipolarly charged parti-cles in an alternating electric field is developed. This coagulation coefficient is further simplified withthe method used in Williams's research on acoustic coagulation. The experiment of collecting smokeparticles is carried out in an electrostatic agglomeration apparatus with alternating electric field. Thealternating field frequency is 2Hz,4Hz and 6Hz respectively. The experimental results have shown thatthe collection efficiency under different frequencies are almost identical,yet the efficiency of collectionat 6Hz is greater than that at other frequencies.
