DEVICE AND METHOD FOR ELECTRIC ANTIFOULING

摘要

PROBLEM TO BE SOLVED: To provide a simple and compact structure device and method to perform antifouling and anticorrosion for various types of parts which directly contact seawater contained in a heat exchanger or condenser. SOLUTION: A cylindrical opening is installed near a cooling water intake pipeline and sealed by a shutoff plate. A supporting plate is installed on the back of this shutoff plate, and inside the water intake pipeline a plurality of polarity-changeable iron electrode plates located in a row which interleave an insulating material are installed in parallel with the water flow and fixed to the supporting plate. On the inner circumference of the water intake pipeline, an insoluble electrode plate is installed interleaving an insulating material, and a plurality of iron electrode plates and this insoluble electrode plate are electrically connected to the outside direct current power supply unit by electrically conductive fastener. These are the outstanding features of the electric antifouling device.
