摘要
对毛细管-环电极配置下的静电雾化进行了试验研究,通过测试雾滴大小,探讨和分析了雾化操作参数对雾滴大小的影响及不同雾化模式下的雾滴直径分布规律.研究表明:充电电压对雾滴大小及直径分布有显著的影响,但在不同雾化模式下,雾滴的大小随电压的变化规律是不同的,雾滴直径分布在不同模式下也呈现不同的分布特点.文中还使用PDA系统对垂直雾化的滴径及滴速进行了在线测试,揭示了不同充电电压下的滴径-滴速特性.
Experimental investigation was performed for electrostatic spraying under capillary-annular electrode configuration. The working parameters of spraying and distributions of droplet diameters at different modes of spraying were analyzed. The result shows that the effect of charging voltage on size and distribution of droplets is obvious. However, the changes of droplet size with voltage at different modes of spraying are different, and the distributions of droplet diameter exhibit different characteristics. In addition, the size and velocity of droplet for vertical spraying were measured, the size-velocity correlation characteristics were revealed at different voltages.
