| 摘 要： | 介绍磁增强电晕放电的特性及其对颗粒荷电的性能.在负电晕放电中,磁场可提高极间自由电子的能量,增加带电粒子的浓度,增大放电电流.在放电极雾化负电晕放电中,磁场可显著提高微小颗粒的凝并效能.采用永久磁铁形成放电极附近较强的非均匀磁场,比均匀磁场对负电晕放电有更好的增强效果.

| Abstract: | The characteristics of the magnet enhancement corona discharges and their functions for charging particles are introduced. The experimental results demonstrated that the magnet field could obviously increase the discharge current and enhance the particle density in corona discharges. The deflection of free electrons between the discharge and collection electrodes was measured. Therefore we can deduce that both the energy and the concentration of free electrons and ions are increased in the magnet enhancement corona discharges. Comparing with the uniform magnet field, the non-uniform magnet field formed by the permanent magnet nearby the discharge electrodes can more effectively intensify corona discharges was developed. An aerosol charger of the magnet enhancement corona discharges with permanent magnet. The charging current was increased by 25% in a magnet field of 0.02T. |
