Abstract

In order to improve spraying results, an inductive electrostatic sprayer was designed. The performance of the sprayer was then tested. The test result shows that the charge-to-mass ratio can reach 0.951 mc/Kg when electrostatic voltage is 20 KV and working pressure is 0.25 to 0.4 MPa. The particle size distribution of charged droplets are more concentrated than that of uncharged droplets, the axial velocity of charged droplets is faster than that of uncharged droplets, and the velocity distribution uniformity is also improved. The average deposition rate under charging conditions is 14% higher than that in uncharged conditions. Moreover, the deposit rate of the back of the leaf is evident.

Highlights

Electrostatic spray technology has superior performance in improving droplet size, size distribution and deposit rate on targets, adsorption, and uniformity
The use of electrostatic spray in various fields has been developed in numerous countries
Electrostatic sprayers and other large sprayers in China are mostly used in the prevention and control of forestry

Summary

Introduction

Electrostatic spray technology has superior performance in improving droplet size, size distribution and deposit rate on targets, adsorption, and uniformity. This technology has long been used in plant protection and epidemic prevention (Wang et al, 2008; Wang et al, 2004; Edward, 2001). The use of electrostatic spray in various fields has been developed in numerous countries. An example is Electrostatic Spraying System, Inc., which has developed a small electrostatic sprayer (Shu et al, 2002). The small electrostatic sprayers are not widely used (Kang et al, 2007)
