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，根据粉尘凝并过程趋于“自保分布”的概念，得出粉尘中位径随凝并时间变化关系式和异极性荷电粉尘在交变电场中的凝并除尘效率近似计算式·提出一种新型双区式电凝并除尘装置，在相同条件下，理论与试验研究结果表明：新型双区电凝并除尘装置的除尘效率不仅高于电除尘器，而且在结构上优于三区电凝并除尘装置·
Similar to Williams’ method of determining the acoustic condensation coefficient, the condensation coefficient of heterosexual charged dust in an alternating electric field is deduced. According to the concept that the dust condensation process tends to be “self-contained distribution”, the median diameter of dust with condensation Time variation relationship and heterogeneous charged dust in the alternating electric field coagulation and dust removal efficiency approximation formula · Proposed a new double-zone coagulation and dust removal device, under the same conditions, the theoretical and experimental results show that: The dust removal efficiency of the new double-zone coagulation and dust removal device is not only higher than that of the electrostatic precipitator, but also superior in structure to the three-zone coagulation and dust removal device
