【 摘 要 】

In this paper, the influence of the diameter of the annular electrode and the arrangement of the nozzle on the droplet in electrostatic spray was studied by experiment and analysis. On the conical spray nozzle, five different diameters of ring electrodes and five mounting positions were used to carry out the jet charged spray test. The net current method was used to measure the charged current, total mass and test time of the droplets. The charge to mass ratio was used to evaluate the inductive charge performance of the droplet. The test results show that the charge increases with the increase of the charge voltage on the electrode. When electrode ring diameter increases, the droplet charge decreases. While the installation position of the electrode moves forward along the direction of the spray, the charge of the droplet increases. There is a linear relationship between the charge and the electrode ring diameter and installation location.
