静电喷雾在农药植保领域的应用与现状分析

Application and Status Quo of Electrostatic Spray in Pesticide Plant Protection

首先从静电喷雾的静电产生、雾滴雾化以及雾滴吸附等基础理论出发,论述了雾滴雾化性能评价指标和方法,并概括性对比分析了3种不同静电充电方式及各自的优缺点,得出在相同情况下感应式充电效果更佳的一般性结论;其次,通过对国内外大型喷雾器械的应用与现状的论述,为我国静电喷雾机械设备的研究和发展明确了方向;最后论述了静电电压、喷雾液压、喷雾速度和环境风速这4个关键因素对静电喷雾雾滴沉积分布的影响,并提出静电喷雾技术在烟草农药施药上的应用研究展望与建议。

Firstly,based on the basic theory of electrostatic spray,atomization and droplet adsorption,the evaluation indexes and methods of fog atomization performance were discussed.Three different electrostatic charging methods and their respective advantages disadvantages were summarized and analyzed.The general conclusion that the inductive charging effect is better under the same conditions was obtainted;secondly,through the discussion of the application and status quo of large-scale spray instruments at home and abroad,the direction of the research and development of electrostatic spray machinery in China was clear;the effects of electrostatic voltage,spray hydraulic pressure,spray velocity and ambient wind speed on the distribution of electrostatic spray droplets were discussed.The application prospects and recommendations of electrostatic spray technology on tobacco pesticide application were proposed.
