THREE-CHAMBER BASED ELECTROLYTIC CELL

摘要

PROBLEM TO BE SOLVED: To provide an electrolytic device for simultaneously obtaining pure acidic water at high ORP from an anode chamber and pure alkaline hydrogen peroxide water at low ORP from a cathode chamber with a high efficiency. SOLUTION: An anode 9 and cathode 8 are also installed in tight contact with an anion exchange membrane 2 and a cation exchange membrane 5 in the intermediate chamber of the three-chamber based electrolytic cell 1 segmented to the anode chamber 3-the intermediate chamber 4-the cathode chamber 6 by the anion exchange membrane and the cation exchange membrane. An oxygen-contg. gas is supplied to the cathode chamber. When the anode 9 and the cathode 8 are electrically connected, there is no more gradient and the perfect and free migration of the ions in the intermediate chamber is made possible. When the anode 9 and the cathode 8 are discretely connected to a power source, the energization quantity by both power source is settable discretely at the optimum the value. The unnecessary energization and the consequent useless energy consumption are averted. The acidic water is obtd. in the anode chamber and the alkaline hydrogen peroxide water in the cathode chamber by such high-efficiency electrolysis.
