WATER ELECTROLYZING DEVICE

摘要

A water electrolyzing device comprising an oxygen separating tank for storin g pure water to be fed to the electrolytic cell, a pure water circulating line arranged to feed the pure water from the oxygen separating tank to the electrolytic cell and to send back the pure water remaining after electrolys is into the oxygen separating tank, a pure water supply line for supplying pure water to the oxygen separating tank or pure water circulating line, a first heat exchanger placed in the pure water supply line, and a first pure water discharge line communicating at its proximal end with the oxygen separating tank or pure water circulating line and extending at its distal end into the outside of the system via the first heat exchanger, wherein in the first hea t exchanger, heat exchange is effected, at the first heat exchanger, between t he pure water supplied via the pure water supplying line and the pure water discharged into the outside of the system via the first pure water discharge line.
