【摘要】 建立了一套大流量荷电喷雾实验系统,并采用网状目标法收集测量荷电喷雾中的剩余电荷。通过测量不同绝缘罩材质、感应带电环的直径以及感应带电环与喷嘴间垂直距离下的喷雾荷质比,系统研究了上述参数对荷电效果的影响。实验结果表明,尼龙材料绝缘罩更有利于细水雾感应带电实验研究的进行;细水雾感应带电量与感应带电环直径呈负相关;为了增大细水雾感应带电量,应尽量将感应带电环与喷嘴的垂直距离控制在一定范围内。该研究结果对于提高液滴的荷电效果、促进荷电水雾在工业方面应用具有重要指.导意义。更多还原

【Abstract】 A set of experimental system of large flow charge spray was established,and the net charge in the charged spray was collected by the mesh target method. By measuring the spray specific ratio of the different insulation cover material,the diameter of the induction live ring and the distance between the induction ring and the nozzle,the influence of these parameters was systematically studied. Experimental analysis showed that nylon material insulation cover is more conducive to the experimental study of water mist induction charge; the charge of the water mist is negatively correlated with the diameter of the inductive ring; to increase the water mist induction charge,the distance between the induction ring and the nozzle should be restrict within a certain range. The results of this study have important guiding significance for improving the charging effect of droplets and promoting the application of charged water mist in industry.更多还原
