静电尘源抑制
dust source control by elect rostatics
(杨晋亚)J Ingdion Chenyuon yizh-静电尘源抑制(dust souree eontrol by elee-trostatics)利用高压静电减少和防止尘源粉尘扩散的一种粉尘抑制方法。一般直接以生产设备的本体、密闭罩壳体或排风管为接地极，或称为收尘极，在其空间中装设电晕线作为负高压的电晕极，当两极之间供给60一IO0kV的高电压时，极间形成高压电场，含尘气流中的气体在高压电场中电离为正负离子，并碰撞尘粒、使尘粒荷电，带正电的尘粒向电晕极运动，带负电的尘粒趋向收尘极，均分别被收集。定期振打电极，使粉尘落人料斗或皮带等设备中(见图)。 二气了7、。. 4勺\11’\u\一9 料仓静电抑尘系统示意 1桩制器:2一料仓;3一22OV电源;4整流升 压器:易一绝缘棒:6一排气管;7一电晕线; 8一进料口:9压紧弹簧静电尘源抑制技术，设备简单，操作容易，除尘效率可达97%以上。常用于抑制小型分散的尘源点，如料仓、皮带落料点、筒磨机出料口及振动筛落料点等的粉尘扩散。 (杨晋亚)
