Patent number: 11530142Abstract: A water treatment apparatus includes: a plurality of plate-shaped ground electrodes; a high-voltage electrode unit having counter electrode portions opposing the ground electrodes, support portions supporting the counter electrode portions, and a voltage receiving portion for receiving a high voltage; a water supply unit for supplying to-be-treated water to between the ground electrodes from above, insulating members each having a lower end portion fixed to a support structure fixing lower end portions of the ground electrodes, and an upper end portion connected to the voltage receiving portion of the high-voltage electrode unit. The lower ends of the support portions of the high-voltage electrode unit are held in a space between the ground electrodes, and a portion where each insulating member and the high-voltage electrode unit are connected to each other is located above the water supply unit, so that electric leak due to the to-be-treated water is inhibited.Type: GrantFiled: March 14, 2018Date of Patent: December 20, 2022Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Teruki Naito, Gaku Oinuma, Yu Kamiya, Yasutaka Inanaga

Patent number: 11279634Abstract: A water treatment device includes, between at least two flat sheet-shaped grounded electrodes vertically disposed so as to be parallel to each other, a sheet-shaped high-voltage electrode having two edges opposing the respective grounded electrodes. The sheet-shaped high-voltage electrode is supported by a plurality of support members, and thus deformation of the high-voltage electrode in an up/down direction and a horizontal direction is suppressed, and the distance between each edge of the high-voltage electrode and the corresponding grounded electrode, i.e., an electric discharge gap length, can be kept even. Accordingly, uniform electric discharge can be maintained between the high-voltage electrode and the grounded electrode, whereby highly efficient water treatment can be realized.Type: GrantFiled: March 14, 2018Date of Patent: March 22, 2022Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Gaku Oinuma, Teruki Naito, Yu Kamiya, Yasutaka Inanaga
