摘要：
In order to find an efficient method for the removal of fine particles,we designed an electrostatic spray separation device to investigate the charged droplet characteristics and removal efficiency of device, and discussed the influences of charged voltage, electrode gaps, and annular electrode radius on the charge-mass ratio of droplet, electric field intensity, particle concentration and spray flow. The experimental results show that the charge-mass ratio of droplet first increases then decreases as the charged voltages increase. Under the same voltage, the charge-mass ratio of droplet decreases as the annular electrode radius increases, and it increases as the electrode gaps increase. The removal efficiency increases up to 88.5% as the electric field intensity increases. In an uncharged case, the removal efficiency declines as the particle concentration decreases, whereas, high efficiency for low particle concentration is obtained with the charged device. And there is optimal removal efficiency when spray flow rate is 540 mL/min under the same electric field intensity. The research results lay an experimental foundation for developing cyclone dust collector of high fine particle removal efficiency. © 2019, High Voltage Engineering Editorial Department of CEPRI.
