Description

[0001]
BACKGROUND OF THE INVENTION

[Prior art]
Conventionally, raw water is supplied to a sealed electrolytic cell, and a direct current voltage is applied between the anode and cathode in the electrolytic cell to perform electrolysis, and acidic water containing a large amount of negative ions gathered on the anode side and on the cathode side. Various water treatment methods and apparatuses for continuously obtaining alkaline water containing a large amount of positive ions gathered have been proposed.
[0003]
As an efficient water reforming device by electrolysis, an electrolytic solution chamber is arranged around the electrolytic chamber of treated water to circulate the electrolyte solution and to release the electrolysis gas generated by electrolysis to the outside air. Discloses a method and apparatus that does not generate waste water. (Patent Document 1)
[0004]
However, these household ionic water production apparatuses can generate weakly acidic (pH around 4.5) or weakly alkaline (about pH 9.5) ionic water from the performance and structure of the ion exchange membrane. Or strong alkaline ionic water could not be produced continuously for a long period of time. Moreover, the produced ionic water has a problem that the pH value changes in several hours to several days and becomes neutral.
[0005]
As a method and apparatus for producing ionic water that maintains a stable pH value over a long period of time, a stable ion pH is obtained by dissolving the components using a ceramic ion exchange membrane whose main component is a crystalline clay mineral such as montmorillonite. Disclosed are a method for producing ionic water that maintains a value, and a method and apparatus for producing strongly acidic or strongly alkaline ionic water by introducing treated water to a plurality of electrolytic cells and repeating electrolysis treatment a plurality of times. . (Patent Document 2)
[0006]
However, in these apparatuses, the electrolytic cell or the electrolysis processing chamber is sealed, and the processing capacity is limited. For this reason, it was not possible to continuously neutralize strong acid water from the abandoned mine, large quantities of running water such as acid river water, or industrial waste liquids such as metal surface treatment waste liquid and plating waste liquid.
[0007]
In addition, in the neutralization treatment of contaminated water, a reaction product (precipitate) is generated along with the neutralization treatment. There was a problem that could not be done. Furthermore, designing and manufacturing an electrolytic cell according to the amount of treated water and the strength of acid / alkali each time has a problem in terms of cost.

[0041]
In addition, at least both lateral sides of the electrolytic treatment chamber 1 are opened, and one and the other side surfaces thereof are a raw water supply port 8 and a drain port 9, respectively.
[0042]
The electrolytic solution chamber 2 is provided with an electrolytic solution inlet 2a and an electrolytic solution outlet 2b.
[0043]
The first electrode 3 and the second electrode 4 are inserted into the electrolytic cell 10 from above and are held by an insulating member support structure (not shown) so as not to fall down. The support structure may be provided on the bottom surface 10a, or may be any method in which an insulating member is sandwiched between the electrode side surface and the electrolytic cell 10 or the ion exchange diaphragm 5. Each of the first and second electrodes 3 and 4 includes an electrode terminal 7 connected to a DC power source (not shown) by an electric wire.

[0045]
Here, an embodiment of water reforming using the water reforming unit 100 by electrolysis of the present invention will be described. FIGS. 4A and 4B are schematic views showing an installation mode of the water reforming unit 100 using electrolysis according to the present invention, where FIG. 4A is a plan view and FIG. 4B is a cross-sectional view.
[0046]
As shown in FIGS. 4 (a) and 4 (b), the water reforming unit 100 using the electrolysis of the present invention is flown through the river 50 so that the water supply port 8 faces upstream and the drain port 9 becomes downstream.

[0047]
In this state, the electrolytic solution chamber 2 is filled with an electrolyte solution (aqueous solution such as sodium chloride or potassium hydroxide), and a voltage is applied to the first electrode 3 and the second electrode 4. The flowing water is electrolyzed by a current flowing between the first electrode 3 and the second electrode 4 when passing through the electrolytic treatment chamber 1, and when the first electrode 3 is a negative electrode, the flowing water is negatively ionized (alkalineized). On the other hand, in the case of the positive electrode, the flowing water is positively ionized (acidified), thereby reforming the flowing water.
[0048]
For example, when neutralizing strong acidic flowing water, if a voltage is applied with the first electrode as a negative electrode, the electrolytic treatment chamber 1 becomes negative ions (in a state where there is a lot of OH ⁻ ) by electrolysis, and the flowing water is drained downstream.

[0052]
Moreover, while flowing water is continuously modified in the electrolytic treatment chamber 1, the electrolytic solution is ionized by electrolysis in the electrolytic solution chamber 2. As ionization progresses, current becomes difficult to flow and electrolysis stops. In order to prevent this, the electrolyte solution is replenished from the electrolyte solution inlet 2a and recovered from the electrolyte solution outlet 2b.
