摘要
针对一种新型电-袋复合除尘器,对环形电场中的粉尘颗粒受力及运动规律进行研究。忽略粉尘颗粒形状等因素的影响,把粉尘颗粒视为理想球体,不考虑复杂流态,把气流视为层流。通过列表计算,对不同颗粒直径和电场风速条件下颗粒所受离心力与其所受静电力进行对比。结果表明,颗粒直径大于或等于10 μm且电场风速达到10m/s以上时,离心力和静电力才能对粉尘颗粒的收集起协同作用。
This paper intends to present its authors＇ analysis of an innovated electrostatic fabric filter, particularly over the force and movement of the dust particles in its annularity electric field, which used to be ignored in the similar treatments. As we know, the studies in this area up to now that has been focused on the factor of the dust particle shape, just taking the dust particle as the ideal spheroid. They didn＇t not pay enough attention to the complicated state of the air stream but only take it as that of the laminar flow. Neither did they pay any attention to the calculation of the diameter of different particles, nor the different wind speeds of the particles in the annularity electric field along with the static electric force it suffers. Therefore, it can be concluded that the function of dust collection can actually be performed by the centrifugal force and the static electric force when diameter of the particles d ≥ 10 μm and wind speed reached 10 m/s or above in the electric field. Thus, the present analysis we have done proves much more valuable to improve the performance of the electrostatic fabric filter and that of the whole device.
