In this research, three types of a new electrostatic liquid filter that utilizes both a. c. and d. c. electric fields, which has been proposed by Yanada, were manufactured on an experimental basis. Two filters are cylindrical in shape and one has a rectangular cross-section : Those three filters consist of the coagulating part, where an a, c. electric field is applied to make minute contaminant particles be coagulated, and of the capturing part, where a d. c. electric field is applied to capture the particles. In the cylindrical filters, the coagulating part is arranged on the outer part of the cylinder and the capturing part in the inner part of the cylinder. Only the difference in the two cylindrical filters is the flow direction in the coagulating part, that of one filter is the direction of the axis and that of another one is circumferential. The difference in the flow direction in the coagulating part leads to a difference in the magnitude of the velocity gradient in the passage there. The rectangular filter was manufactured to examine the effects of the shape and arrangement of the collector and electrode in the capturing part on the filter performance. It is shown that the filtration speed can be approximately doubled by utilizing both the a. c. and d, c. electric fields compared to the case where only the d. c. electric field is used, and the usefulness of the electrostatic liquid filter proposed is demonstrated. The comparison between the performance of the two cylindrical filters shows that the magnitude of the velocity gradient in the passage in the coagulating part strongly affects the filter performance. In addition, it is shown that the filter performance can be increased by appropriately designing the shape and arrangement of the collectors and electrodes in the capturing part.

在这项研究中，三种类型的新型静电液体过滤器，利用两者。C.和d. C. Yanada提出的电场是在实验基础上制造的。两个过滤器是圆柱形的，一个具有矩形横截面：这三个过滤器由A部分组成，其中a，c。施加电场以使微小污染物颗粒凝结，并且在捕获部分的d. C.施加电场以捕获颗粒。在圆柱形过滤器中，过滤部分布置在圆柱体的外部部分上，而捕获部分布置在圆柱体的内部部分中。两个圆柱形过滤器的区别仅在于在过滤器部分中的流动方向，一个过滤器的流动方向是轴线方向，而另一个过滤器的流动方向是周向方向。在环形部分中的流动方向的差异导致在那里的通道中的速度梯度的大小的差异。制造矩形过滤器以检查捕获部分中的集电器和电极的形状和布置对过滤器性能的影响。结果表明，采用两种过滤方法，过滤速度可提高近一倍。C.和d，c.电场相比，只有d. C.电场，并证明了静电液体过滤器的实用性。两种圆柱形过滤器的性能比较表明，在过滤器的过滤性能的强烈影响的速度梯度的大小在通道中的第二部分。此外，还表明，通过适当地设计捕获部分中的集电器和电极的形状和布置，可以提高过滤器性能。
