Collecting fog water from the atmosphere or industrial waste gas can not only replenish water resources, but also improve the atmospheric environment. However, the efficiency of the traditional fog mesh collector is not satisfactory. Different to inefficient fog meshes, collecting droplets by corona discharge is a potential method that can effectively improve the collection efficiency of fog. This research proposes an electrostatic fog collector using multiple mesh droplet collecting electrodes with an electric field, which realizes the efficient collection of fog. The electrostatic fog collector consists of three parts: charged electrode, multiple mesh collecting electrodes and resistor divider. The influence of mesh size, the number of the mesh electrodes, and the electric field on the collecting rate are all studied experimentally. The experimental results show that the collection efficiency of the electrostatic fog collector using 5 collecting electrodes with electric field is as high as 82%. Under the action of the electric field, the power consumption of the electrostatic fog collector is only increased by 1.06 times, but the collection efficiency of each mesh droplet collecting electrode is increased by 4 ~ 5 times. In addition, the mesh size selection strategy is studied, and the optimal mesh size scheme is also discussed.

从大气或工业废气中收集雾水，既可以补充水资源，又可以改善大气环境。然而，传统的雾网收集器的效率并不能令人满意。与低效的雾网不同，电晕放电收集液滴是一种可以有效提高雾收集效率的潜在方法。本研究提出了一种采用带电场的多个网状液滴收集电极的静电雾收集器，实现了雾的高效收集。静电集雾器由带电电极、多个网状集尘电极和电阻分压器三部分组成。实验研究了网格尺寸、网格电极数量和电场对收集率的影响。实验结果表明，采用5个带电场的收集电极的静电雾收集器的收集效率高达82%。在电场的作用下，静电集雾器的功耗仅增加1.06倍，但每个网状液滴收集电极的捕集效率却提高了4~5倍。此外，研究了网格尺寸选择策略，并讨论了最优网格尺寸方案。但每个网状液滴收集电极的收集效率提高4～5倍。此外，研究了网格尺寸选择策略，并讨论了最优网格尺寸方案。但每个网状液滴收集电极的收集效率提高4～5倍。此外，研究了网格尺寸选择策略，并讨论了最优网格尺寸方案。
