ANTIFOULING DEVICE OF SEA WATER PUMP AND SEAWATER ANTIFOULING METHOD
To provide an antifouling device of a sea water pump and a seawater antifouling method which can suppress marine biological deposit and breeding effectively over a wide area of seawater duct in a seawater intake system.SOLUTION: In an antifouling device of a sea water pump, a cathode of a direct-current power source 52 and a tailing body 50a as an anode are connected electrically, an anode of the direct-current power source 52, a pump body 31 as a cathode and a metal thing 51 as an auxiliary cathode are connected electrically respectively. Electrolytic protection for the pump body 31 is performed by electrolysis of seawater around the anode with direct current flowing from the direct-current power source 52 to generate chlorine, flowing a part of the direct current from the direct-current power source 52 to the cathode, and flowing the remaining direct current to the auxiliary cathode. The tailing body 50a has a screen structure which is immersed in seawater in use and can remove impurity in seawater physically, and the surface of the screen structure is coated with an electrocatalysis which is active electrochemically and is stable.SELECTED DRAWING: Figure 4
【課題】海水取水系統における海水流路の広範囲にわたって海生生物の付着・繁殖を効果的に抑制し得る、海水ポンプの防汚装置及び海水防汚方法を提供すること。【解決手段】海水ポンプの防汚装置においては、直流電源５２の正極と、陽極としての異物除去体５０ａとが、電気的に接続され、また、直流電源５２の負極と、陰極としてのポンプ本体３１及び補助陰極としての金属物５１とが、それぞれ電気的に接続されており、直流電源５２から流れる直流電流により該陽極の周辺の海水を電気分解して塩素を発生させ、また、直流電源５２から直流電流の一部を該陰極に流入させ且つ該直流電流の残りを該補助陰極に流入させて、ポンプ本体３１に対して電気防食を行う。異物除去体５０ａは、使用時に海水中に浸漬され海水中の夾雑物を物理的に除去し得るスクリーン構造体を有し、該スクリーン構造体の表面が、電気化学的に活性で安定な電気的触媒で被覆されている。【選択図】図４
