Design and Test of an Air-assisted Electrostatic Nozzle

In order to solve the problems of easy adsorption of charged droplets at the nozzle and easy attenuation of the charged power in the direction of range, the air-fed electrostatic nozzle was designed by combining airflow-assisted spraying and electrostatic spray technology. Theoretical analysis and experimental methods were used to determine the structure and parameters of the induction electrode and the structure and parameters of the airflow channel. The results of the nozzle performance test showed that when the spray distance was greater than 1.5m, and the electrostatic spray lost its effect. This study provides technical support for the popularization and application of electrostatic nozzles, and provides a reference for the design of large-scale sprayers with this type of nozzle as components.
