Studies On Induction Charging And Pneumatic Energy Electrostatic Nozzle

Aimed at some problems such as short spraying distance, electricity-leaking and reverse ionization among electrostatic nozzles existing in the country, a induction charging and pneumatic energy electrostatic nozzle was designed .The basic designing theories , structure and working process of this nozzles were theoretically specified in the paper. And then the atomization quality and charge performances of this nozzle and its affecting factors were studied by carrying out performance experiment and statistic analysis. Result of the studies indicate: (1)some progress were made in solving the problems list above;(2)from this nozzle, droplet were minute and uniform, and higher charge-mass ratio can be obtained under lower electrostatic voltage, thus the atomization quality and charge performance of this nozzle were both better;(3)within the experiment extend, air pressure at 0.2Mpa,electrostatic voltage at 2400V were the most suitable parameters for the nozzle;(4)the regression equations for describing droplet size , intensity of spray current and charge-mass ratio of this nozzle obtained from the experiment data had higher forecast precision;(5)cross-effect of all factors were not significant , the atomization quality and charge performance were relative dependency affected by the factors. Studies on induction charging and pneumatic energy electrostatic nozzle will lay a foundation for the design and study of some other electrostatic nozzles.
