摘　　要：设计一种空心圆锥雾仿形静电喷头,通过在雾滴形成区域施加仿形静电电极,并对电极加以高压绝缘外套设计,使得雾流与电极间以最佳感应距离获得最大静电感应电荷。试验结果证明:对于选用的流量为290mL/min、锥角80°的空心圆锥雾喷嘴,其荷质比可达0.79mC/kg,而韩国同类静电喷头的荷质比仅为0.27mC/kg。A hollow cone nozzle with profiling electrostatic electrode was designed by applying profiling electrostatic electrode in the mist region and designing high-voltage insulation protection, and mist flow could obtain the maximum electrostatic charge in the best induction distance with electrode. The experi- ment proved the charge to mass ratio is up to 0.79mC/kg for the hollow cone nozzle which flow is 290mL/min with 80° cone angle, and similar electrostatic spraying charge to mass ratio is only 0.27mC/kg in South Korea.
