摘要
为了提高高压静电分选效率,探究转辊表面电流分布规律。采用自制的线-辊式高压放电装置,当外加电压固定为35 kV时,改变单根、两根和三根电晕线与转辊表面的间距及相对角度,使电晕线对1/4的转辊表面进行放电。实验结果表明:1)在相同放电间距下,单根电晕线直径越小放电电流越大,转辊表面电流以电晕线正对位置为中心,整体呈正态分布;2)两根电晕线放电时,线间电场相互排斥,转辊表面电流分布范围扩大;3)三根电晕线放电时,在两外侧电晕线夹角为60°,中间电晕线与转辊表面间距为4.5 cm的位置,测得的电流覆盖范围较大,三个峰值电流相差较小,峰值平均电流为21.167μA,外侧两峰值夹角约为72°。
In order to improve the efficiency of high-voltage electrostatic,the current distribution characteristics of the roller surface were explored.The experimental device of high-voltage discharge was made.In the process of experiment,the wires were used to discharge to a quarter of the drum surface under 35 kV voltage.Change the distance and relative angle between the different kinds of corona line and the surface of the roller.The results indicated that:1)The smaller was its radius,the bigger was the discharge current under the same distance.The current on the surface of roller was close to normal,its center was at the position where the wire was.2)When two corona lines were discharging,the electric field was outward migration because of the mutual inhibition dual discharge.3)When three corona lines were discharging,at one position,current distribution range measured was comparatively bigger and three peaks were relatively stable.In this case,the angle between two outer corona lines was 60°,and the distance between the corona line and the surface of the roller was 4.5 cm.The mean value of peak current was 21.167μA and the lateral angle between two peaks was about 72°.
