Description

[Detailed Description of the Invention] The present invention provides alkaline water and acidic water directly connected to a raw water source such as public water supply. This invention relates to an ionized water generating device that continuously generates ionized water.

FIG. 1 is an explanatory diagram of the configuration of a conventional ionized water generator.
- In the construction shown in the figure, a partition wall 3 is arranged between the anode 1 and the cathode 2 to divide the anode chamber 4 and the cathode chamber 5 into an anode chamber 4 and a cathode chamber 5, and raw water is supplied to each chamber 4.5 from a water supply port 6, Acidic water is spewed out from an outlet lower communicating with an anode chamber 4, and alkaline water can be taken out from an outlet 8 communicating with a cathode chamber 5.

In such an ion water generation device, the power consumption required to generate alkaline water with a desired pH value is determined by the sliding voltage and current efficiency (1111 electrolysis voltage), which is related to the pH value of the alkaline water. ). As the means for reducing the cell voltage (17), there are two possible methods: narrowing the gap between electrodes and increasing the area of the electrodes. However, if the distance between the electrodes is made extremely narrow, the current efficiency will drop significantly. This means that the sparrow energy structure cannot be achieved simply by narrowing the distance between the poles.

However, if the electrode surface & is made as large as possible, this will lead to an increase in the size of the device.

Furthermore, when the VC partition 3 is arranged as shown in FIG. 1, it becomes difficult to hold the partition parallel to the electrodes.

Therefore, in the case of conventional equipment, although it is possible to extract alkaline water by raising the pHi with a large equipment that consumes a lot of power, if you use a small equipment that consumes less power, the amount of light Kpl* The present invention is a novel invention that improves the above-mentioned conventional drawbacks, and its purpose is to provide a small-sized, high-performance ionized water generator. Below, examples will be explained in detail based on the drawings@
Figure 2 is a main part-1 section of an embodiment of the present invention, and as shown in the fourth section, a water-permeable 11M
Cathode 12♂, IIJNl installed near wall wall 13

and the pasted 12 pieces are passed through 7) - so as to be fed to the downcomer 14 - (as well as the ls electrode 11 and the water permeable partition member) 3 are communicated with the acidic water outlet 16, and the cathode down Comer 14”￥Connected to alkaline water outlet 17 (
The composition is poor in 7.

In the above, the anode 11 is made of ruanium oxide, palladium oxide, or iridium oxide on titanium.

White metal oxidation such as saponified platinum? /I ＞'Metal 8 made by coding! is preferable, and in the embodiment, it is also possible to adopt this (-, but also σ of the network structure). The cathode 12 is made of a stainless steel plate 1-) formed by punching a large number of holes in a staggered manner. Stainless steel plates formed by combining SQ sheets can also be used. ′! Water-permeable 11M wall member [3] Water-permeable materials such as rayon non-woven fabric and polyester non-woven fabric can be appropriately selected and used.

In addition, in the present invention, it is preferable that the water-permeable partition member 13 is provided in a shaded manner (σ), and this is adopted in the embodiment.

As mentioned above, it is recognized that when the water-permeable partition member 13 is provided near the cathode 12, the pole N12 between the anode 11 and the cathode 12 can be narrowed considerably without reducing the current efficiency. G to closely support the cathode 12
) In this case, due to the mechanical stability of the water-permeable partition wall side 13, no decrease in current efficiency was observed even when the electrode gap was narrowed by 2-1 in experiments. This solves the problem of reducing the sliding voltage.

Furthermore, the present invention provides a part of the supply water that flows between the positive side 11 and the water-permeable partition wall side 13 (in this embodiment, the part of the water flowing in the cathode downcomer 14).
Since hydrogen gas is fed to the cathode downcomer 14 with a Y bend (7), hydrogen gas bubbles generated and stagnant on the surface of the cathode 120, especially between the water-permeable partition member 13 and the cathode 12, grow. Now it comes out easily without any problems,
This made the current distribution of the cathode I2 uniform, and the current efficiency was significantly improved.

Now, to explain the shape of the punched stainless steel plate used for the cathode 12 in more detail, if the holes are too large, the current distribution will become uneven and the current efficiency will decrease, while if the holes are too small, air bubbles will escape. is not good and the current distribution becomes uneven.

FIG. 3 is a characteristic curve showing the relationship between pHfiM of alkaline water and electrolytic electricity (CC/l) I/C,
In 1jl-, song #A is the ionized water generator vJSa with the structure of the present invention, and song INB is simply the narrowing of the gap between the electrodes, and the use of a water-permeable partition member! This is a case where raw water is supplied to 1flI@. However, in both cases of -1 curve A and curve B, electrode effective area: x4oy, polar separation: 2 haze.

Quad downcomer depth = 9 cm, water permeable partition member: polyester nonwoven fabric, raw hydric acidity is 30 ppm.

Curve A and song i! As can be seen by comparing with B, by applying VC1C1 to the configuration of the present invention, for example, the amount of electrolytic electricity is 10
0 (C//), the alkaline water has a pH of about 9.0, whereas in the configuration to which the present invention is not applied, the pH of the alkaline water is only slightly higher. Although not shown because the conditions are different, in the case of the 11th N conventional structure, the pH of alkaline water did not rise easily.

In this way, the configuration of the present invention is extremely effective in reducing cell voltage and improving flow WE. In this case, as in this example, a metal plate coated with white metal oxide on titanium is used as the anode l] and t=r.
It can withstand light even under high-density usage conditions2, has lower overvoltage than longitudinal cables and ferrite, and can be made smaller and lighter.

Note that in the configuration of the present invention, a portion of the water σ) supplied to the anode 11111-1 is supplied to the cathode 12 side through the water-permeable partition member 13, so C0j-, which is involved in CaCO5 generation, is transferred to the anode by electrostatic effect. I thought that it would be effective to keep the force at a, but as a result of the experiment, the effect of reducing the adhesion and reduction of the force on the cathode surface was not at all longer than r〇〇σ) As is clear from Kinmei. According to the present invention, the compact and high-performance ionized water generator iI is extremely effective in reducing sliding electric power generation and significantly improving efficiency.
It can be manufactured easily and reliably. As a result, it is possible to efficiently obtain the desired σ) pH value σ) alkaline water with low power consumption, even when using buffer water such as underground water, which was traditionally difficult to use with a directly connected water supply θ) ionized water generator. ,
Versatility) can be significantly improved (7 times).
