Development of a Fog-Liquefier Composed of Wire and Rod Electrodes

在我国北方地区的太平洋沿岸，沿着有周期性的寒冷东风，称为“山濑风”，经常造成浓雾。由于气温低，日照不足，许多农作物经常遭受严重的寒冷天气损害。此外，浓雾造成能见度低，给所有交通服务造成严重的麻烦。为了采取对策，我们最近研制了一种人工除雾器--静电除雾器，在实验室和室外都取得了良好的效果。然而，由细网电极组成的装置易受强风的影响，因此需要经常修理。本文介绍了改进型静电除雾器的研制基础研究，即用细网电极代替棒状电极。从基本实验中我们得到以下三个结果，认为这是离子风引起的。棒状电极排列的液化效率是网状电极排列的几倍。粗棒状电极的液化效率并不一定比细棒状电极高。在离子风和雾流速度几乎相同的情况下，液化率最大。实验中将线电极和棒状电极排列成一条直线在雾流中，电极排列方式的选择是采用锯齿形电极排列还是采用锯齿形电极排列，电场分布和离子风流动也是需要分析的问题。

Along the Pacific Coast in our northern regions.we have a periodic very cold east wind called "YAMASE wind" which results frequently in a dense fog.As it is accompanied by low temperatures and by lack of sunshine, many crops have frequently suffered serious cold weather damage.In addition, poor visibility due to dense fog has caused serious troubles to all traffic services.In order to take countermeasures against such troubles, we have recently developed an artificial for-eliminator called the electrostatic fog-liquefier and obtained good results not only in our laboratory but also in outdoors.The apparatus composed of fine meshelectrodes, however, tended to be affected by a strong wind, so it needed frequent mending.Our report describes basic researches on development of the modified model, in which we exchanged fine mesh electrodes for rod ones. From the fundamental experiments we getfollowing three results, and consider they are caused by ionic windEffciency of rod eiectrode arrangement is several times as that of the mesh electrode arrangement.A thick rod is not always more efficient that a thin rod.The maximum liquefied rate is observed in case of almost the same veiocity of the ionic wind as that of the fog flowIn experiments we arranged wire electrodes and rod ones in a line aiong the fog flow.We intend to make experiments to examine which of electrode arrangements of above mentioned type or zigzag one we should choose.Electeic field distributions and ionic wind flows are also problems to be analyzed.
