Abstract
The electrostatic atomization effect of liquid in high voltage electrostatic field was studied under capillary-flat electrodes. The effects of charging voltage, liquid flow rate, and the distance between a capillary and flat electrode on droplet size distribution were analyzed by the DP-02 laser particle size analyzer. The single-factor method was used to analyze the effects. The experimental results show that the charging voltage, the liquid flow rate, and the distance between the capillary and the plate electrode greatly influence the droplet's atomization effect. The median particle size D50 and the distribution span (Span) decrease with the increase of charging voltage, the reduction of liquid flow and the decline of the distance between capillary and plate electrode. That is, the droplet particle size distribution is better, and thus the droplet electrostatic atomization effect is better.
