Abstract

There is provided an apparatus for producing strong alkaline reductive electrolyzed water and acidic water that enables efficient production of electrolyzed water that has excellent washing and sterilizing effects.

There is provided an apparatus for producing strong alkaline reductive electrolyzed water and acidic water, which comprises an electrolyzer provided with a strong alkaline reductive electrolyzed water-producing chamber, an acidic water-producing chamber and a partitioning membrane, wherein a flow path diffusing device is provided in the electrolyzer, and a gap between the cathode plate and the anode plate of 0.1 mm to 1 mm.

Claims

1. An apparatus for producing strong alkaline reductive electrolyzed water and acidic water, which comprises:

an electrolyzer for producing strong alkaline reductive electrolyzed water and acidic water comprising;

a strong alkaline reductive electrolyzed water-producing chamber provided with a cathode plate, and a raw material water introducing inlet and a strong alkaline reductive electrolyzed water draining outlet,

an acidic water-producing chamber provided with an anode plate, and a raw material water introducing inlet and an acidic water draining outlet, and

a partitioning membrane for partitioning the alkaline reductive electrolyzed water-producing chamber and the acidic water-producing chamber,

wherein a flow path diffusing device acting so that the raw material water and an electrolyte to be introduced into the electrolyzer together with the raw material water make contact effectively with the whole surface of the cathode plate and that of the anode plate, is provided in the electrolyzer, and

a gap between the cathode plate and the anode plate of 0.1 mm to 1 mm.

2. The apparatus for producing strong alkaline reductive electrolyzed water and acidic water according to claim 1, wherein a circulating path for circulating strong alkaline reductive electrolyzed water or acidic water drained from the strong alkaline reductive electrolyzed water draining outlet or the acidic water draining outlet, and again introducing the water into the electrolyzer, is connected to either the strong alkaline reductive electrolyzed water draining outlet or the acidic water draining outlet.

3. The apparatus for producing strong alkaline reductive electrolyzed water and acidic water according to claim 2, wherein an electrolyte supplying container filled with 1 or 2 or more additives selected from the group consisting of calcium carbonate, sodium bicarbonate, sodium chloride, ammonium chloride, calcium chloride and potassium chloride, is provided in the circulating path in order to simply supply electrolyte components in the electrolyzer which had been lost by electrolysis.

4. The apparatus for producing strong alkaline reductive electrolyzed water and acidic water according to claim 3, wherein an additive to be filled in the electrolyte supplying container is pellet-like or solid-like.

5. The apparatus for producing strong alkaline reductive electrolyzed water and acidic water according to claim 2, wherein a gas releasing device for releasing oxygen gas and hydrogen gas produced in the electrolyzer to the outside of the apparatus is provided.

6. The apparatus for producing strong alkaline reductive electrolyzed water and acidic water according to claim 2, wherein a raw material water-automatically supplying device for automatically supplying raw material water at the same amount as that of decreased raw material water when raw material water circulating in the circulating path is decreased, is provided.

7. The apparatus for producing strong alkaline reductive electrolyzed water and acidic water according to claim 1, wherein an electricity source for supplying electricity to the cathode plate and the anode plate is a constant current type direct current electricity source.

8. The apparatus for producing strong alkaline reductive electrolyzed water and acidic water according to claim 7, wherein a voltmeter for measuring the voltage value of the constant current type direct current electricity source, and a detecting device for informing the case where the voltage measured by the voltmeter is above a set voltage are provided, whereby, a supply and exchange time for the electrolyte can be informed.

9. The apparatus for producing strong alkaline reductive electrolyzed water and acidic water according to claim 1, wherein as pre-treatment of raw material water to be introduced into the strong alkaline reductive electrolyzed water-producing chamber, an impurity-removing device for removing substances interfering with the productivity of alkaline water from the raw material water is provided.

10. The apparatus for producing strong alkaline reductive electrolyzed water and acidic water according to claim 9, wherein the impurity-removing device is one apparatus, or a combination of 2 or more apparatuses selected from the group consisting of a RO membrane filtering apparatus, a UF membrane filtering apparatus, an ion-exchanging resin treating apparatus, an active carbon treating apparatus and a zeolite treating apparatus.
