Analysis of Factors Affecting Inductive High Voltage Electrostatic Spray Droplet Charged Effect
摘要
Abstract
AnTo obtain better droplet charged result under the condition that the charging voltage is limited, the experi-ment model of droplet charge process was firstly established in this paper, then the key parameters that affect the charging effect of droplets were calculated, and two different electrodes( ring and copying) was used to design four kinds of high voltage electrode scheme by selecting three key technical parameters of high-voltage electrodes. Insulation layer with 2 mm and 2 . 5 mmthickness was applied to design eight different high voltage electrostatic shield for cone nozzle TR 80-04 of 80 degrees. Charge mass ratio was used to evaluate the charged result which was measured by combining mesh target and Faraday cylinder. Experimets showed that the charged effect of copying electrode was obviously better than that of ring electrode, electrode width and center to the jet axial distance had a positive correlation with droplet charge mass rati-o. This paper provided reliable theory and experimental basis for the design of high voltage electrostatic cover.关键词
