Study on the Relationship of Electrode and Charge Characteristic in Electrostatic Spraying

Abstract

In this paper, the full factor jet charged spray test was carried out by using the installation position and the annular electrode of different diameters. The influence of the charging voltage, the diameter of the electrode ring and the installation position on the charge of the droplet was analyzed in detail. The characteristics and mechanism of the droplet were theoretically analyzed. The test results show that there is a linear relationship between the charge and the diameter and installation location of the electrode ring. Through further analysis, the empirical formula of the relationship between charge coefficient and electrode parameters and location is built. This formula can be used to calculate and predict the charge capacity of induction electrode. It also could provide a scientific basis for electrode parameters and reasonable design of electrostatic sprinkler.
