DEVICE FOR REMOVING SCALE IN COOLING WATER AND METHOD FOR REMOVING SCALE USING THIS DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a device for removing scale in cooling water which is excellent in durability and maintainability.;SOLUTION: The device 10 for removing scale in cooling water precipitates and removes scale components in the cooling water supplied to a heat exchange system 11 such as a cooling tower by electrolytic treatment has an electrolytic cell 12 for electrolyzing the cooling water supplied to the heat exchange system to circulate and supply the cooling water to the heat exchange system, a plurality of electrode plates 13a-13d installed in the electrolytic cell, a relay box portion 14 for switching a connection circuit configuration formed by the electrode plates, a power source portion 15 for applying a voltage, set by the relay box portion, between the electrode plates, and an electrolysis control portion 16 for controlling the relay box portion based on a change in power supply voltage of the power source portion in constant current control for supplying a constant current between the electrode plates.;COPYRIGHT: (C)2010,JPO&INPIT
