PREVENTIVE METHOD AGAINST CLOGGING OF MARINE ORGANISM

PROBLEM TO BE SOLVED: To retain the activation of the surface of an electrode and prevent marine organisms from clogging, by giving oscillation or bubbling to an anode plate in an electrical anti-pollution method to remove a harmful film generating on the surface of electrodes. SOLUTION: A DC current source 22 for an electrical anti-pollution device is installed in the outdoors. An electrical source 22 and a steel electrode plate 2 and an electrical anti-pollution electrode 21 are connected to a conductor pipe 24 through a connection box 23. The conductor pipe 24 is connected to the electric anti-pollution cathode 21 along a conductor post 25 through the upper structure 13 of an intake way. An air pipe 3 for bubbling is fixed along the lower part and the side end of one side wall face of the electrode 2 and arranged with angles 35 and anchor bolts 36. Air holes 34 are bored at every specified distance on the air pipe 3 and the pipe is erected through the upper structure 13 of the intake way and connected to a compressor through an outdoor solenoid valve 33 and a pressure-adjusting valve 32.
