摘要
为提高高压静电分选效率,须对针型电极结构进行优化。采用自制排针-辊式高压放电装置,通过改变电晕电压、排针与辊面距离、排针与辊面夹角及排针数,分析了各因素对放电电流的影响,研究了1/4辊面电流的分布特性。结果表明:(1)其它条件一定,单排针与辊面距离越小,放电电流越大。排针-辊间距为80 mm,100 mm,120 mm时,辊面分电流极大值分别为6.78μA,5.3μA,3.34μA。(2)采用双排针结构,辊面分电流有两个极大值,电晕电压23 kV时,双排针和单排针总电流相等,24-33 k V时,双排针总电流大于单排针。(3)采用三排针结构,辊面分电流有三个极大值。两侧两排针对中间一排针有排斥作用,三排针与水平方向夹角分别为30°,45°,60°和15°,45°,75°时,两侧电流极大值约为中间电流极大值的3倍和4倍。
To improve the efficiency of separation electrostatic,the structure of needle electrode required to be optimized.The influence of various factors on discharge current and the current distribution on a quarter of the roller surface were investigated by changing the corona voltage,the distance between needles and roller,the angle between needles and x axis,and the number of rows of needle using a self-made needle-roller discharge device.The results show that:(1)Under other conditions remain unchanged,if we change the distance between the needle and the roller,the smaller the distance is,the greater the discharge current will be.When the distance between needles and roller are 80 mm,100 mm,and120 mm,sub-current maxima values on roller surface are respectively 6.78μA,5.3μA,3.34μA.(2)For double needle,its corresponding sub-current on roller surface has two maxima,when the corona voltage is 23 kV,total current of double row needle is equal to the total current of single row needle,when the voltage is in the range of 24-33 kV,total current of double needle is greater than the total current of single row needle.(3)For three rows of needle,sub-current on roller surface has three maxima,and both sides for two rows of needles have a rejection effect on the middle row of needle,Both sides of the sub-current maxima values are respectively about 3 times and 4 times of the sub-current maxima value in the middle when angle between needles and x axis are respectively 30°,45°,60°and 15°,45°,75°.
