水溝がコンクリートの場合はブラントの休止時に人工的
に付着生物の除去作業を行うか、または塩素注入して海
洋生物の付着を防止する手段が採られている。Since marine organisms adhere to the walls of the water intake groove, there are problems such as the attached organisms falling off and damaging the blunt, or the intake groove being narrowed by the attached organisms, resulting in insufficient cooling capacity. If the intake groove is made of steel pipes, the surface should be coated with antifouling paint to prevent marine organisms from adhering to it, or if the intake groove is made of concrete, artificial removal of attached organisms should be carried out when the blunting is stopped. Measures are being taken to prevent marine organisms from attaching to the water, such as cleaning or injecting chlorine.
発電ブラントの取水溝は縦横それぞれ数ｍ、長さ数百ｍ
に及び、取水溝壁面に付着する海洋生物の厚さは数十国
となるため膨大な量となり、除去作業、廃棄作業には極
めて困難が伴う。The water intake groove of the power generation brand is several meters long and several hundred meters long.
The thickness of the marine life that adheres to the walls of the water intake ditch is several dozen countries, which is an enormous amount, and removal and disposal work is extremely difficult.

まり画用されていない。Intake of seawater for cooling in power plants is essential for maintaining plant performance, so measures have been taken such as installing two lines of intake ditches and cleaning the intake ditches alternately without shutting down the plant. Equipment is expensive. In addition, there is a method of injecting chlorine into the water intake channel to prevent biofouling, but since chlorine is injected into the entire water intake, the concentration of chlorine ions in the surrounding seawater becomes high when draining water, which can lead to problems with aquaculture. This method is not widely used because it affects the people who make a living in the area.
本発明は上記技術水準に鑑み、海水の取水溝を合目的に

If it is less than Ω.tan, conduct this conductivity in seawater by using the paint as the anode and a separate metal member as the cathode, or use the conductive paint on one side of the insulated split as the anode and the other conductive paint as the cathode. When electricity is applied as a cathode, seawater is electrolyzed and hypochlorite ions fr are generated. At this time, hypochlorite ions (this concentration is around a 1 ppm) generated under the conditions of a current density of a 01 A/m or higher and an anodic polarization potential of 1000 mV or higher in seawater can cause the adhesion of marine organisms in the intake ditch. sufficiently prevent

とするものである。In order to maintain current distribution over a wide range, the volume of copper or nickel in the coating is reduced by using the above-mentioned conductive paint as an upper layer, a highly conductive paint such as copper thread or nickel powder as a conductive material, and the above-mentioned binder. It is practically advantageous to coat the lower layer with a highly conductive paint having a ratio of 50 to 40% (volume resistivity 10 to 10 Ω·1). Also, instead of coating the lower layer with a highly conductive paint, highly conductive metals (such as At, C, etc.) are also used.
U, etc.) or metal oxide plates or thermal spraying plates are installed on the downstream side, and all technical colleges 1 (volume resistivity 10 to 10 Ω・a) are installed on the downstream side.
It is also practically advantageous to do so. If you want to create a highly conductive and electrolytic resistant conductive paint with only one layer, the only way to create two layers, upper and lower, is to use platinum as the conductive material, but it is not practical due to cost considerations. is not possible, so
This is a combination in which the lower layer is made to have a technical strength and the upper layer is made to be electrolytically resistant.

00μm, and when using a two-layer film, the descending clarity is 100-200μm,
It is practical for the upper layer to have a thickness of 200 to 400 μm, but since it affects the life of the artist, it is important that the antifouling performance is not affected.
The thickness is not particularly limited.

When it becomes an anode, the spring μ of the series (B) becomes a cathode, and '1 is arranged so that the polarity of each panel is reversed by switching the air circuit, and it becomes a cathode as in the embodiment shown in FIG. This eliminates the need to dispose a metal member in the cross-sectional space of the water intake groove.
