Description

  The present invention relates to an apparatus for producing water containing hydrogen molecules (hereinafter abbreviated as “hydrogen water”) and a method for producing the hydrogen water, and more specifically, an apparatus for producing hydrogen water having an increased dissolved hydrogen concentration, and the method The present invention relates to a method for producing hydrogen water.

  Part of the oxygen taken into the body may be converted into a highly reactive state called active oxygen in the metabolic process. Active oxygen has the following adverse effects on the human body.

1. Production of lipid peroxides: Water-insoluble lipids (ester-type cholesterol, neutral fat) are transported in the blood as lipoproteins by binding apoproteins. Among lipoproteins, 90% of low density lipoprotein (LDL) is lipid, and after oxidation, it contains the most lipid peroxide. When oxidized LDL is formed in this way, arteriosclerosis occurs.
2. Decrease in enzyme activity: When an enzyme protein is oxidatively denatured, the enzyme activity decreases and the function of the cell decreases.
3. Onset of arteriosclerosis, myocardial infarction, cerebral infarction: Oxidized LDL damages vascular endothelial cells and causes arteriosclerosis, making it easy to make blood clots.
4). Carcinogenesis: All active oxygens damage nucleic acids. Cells become cancerous when DNA is oxidized and damaged, and cell death occurs.
5. Promotion of aging 6. Shortening of life Cataract 8. Skin spots 9. Alzheimer's disease Kidney disorders 11. Redox control: Active oxygen ultimately acts to suppress insulin secretion, causing diabetes and the like.

  On the other hand, since hydrogen molecules are harmless to the human body and have reducibility, hydrogen water is considered suitable for eliminating active oxygen.

  However, the dissolved molecular hydrogen in the water is unstable and quickly evaporates from the water, resulting in a decrease in the dissolved hydrogen concentration.

  Hydrogen water can be produced by dissolving hydrogen molecules in water by electrolysis of water to generate hydrogen molecules or hydrogen gas injection in which hydrogen gas is bubbled in water through a porous tube and injected. The law is known.

  In order to efficiently erase active oxygen, it is necessary to increase the dissolved hydrogen concentration of hydrogen water. However, it is difficult to increase the dissolved hydrogen concentration regardless of the electrolytic method or the hydrogen gas dissolving method.

  Generally, the dissolved hydrogen concentration of hydrogen water is 0.5 ppm or less in a steady state at normal temperature and pressure. Of course, there may be a higher dissolved hydrogen concentration transiently, but the dissolved hydrogen concentration of hydrogen water is 0.5 ppm or less in a quasi-steady state one day after production.

  As a method for stabilizing and activating hydrogen water by allowing hydrogen molecules and hydrogen ions to coexist, Patent Document 1 also discloses that the dissolved hydrogen concentration is about 0.8 ppm.

  The reason why the dissolved hydrogen concentration is lowered is considered to be that the hydrogen gas generated at the cathode electrode coalesces and the hydrogen gas is volatilized.

  The state of coalescence of hydrogen gas fine bubbles generated in the two-chamber electrolytic cell 3 in FIG. 11 will be described.

Hydrogen gas is generated by cathode electrolysis in an electrolytic cell. The electrolytic cell is a two-chamber electrolytic cell in which a cathode chamber 5 having a cathode electrode 4 and an anode chamber 8 having an anode electrode 7 are separated by a diaphragm 6 made of a cation exchange resin. 3 and the generated hydrogen water is stored in the water storage tank 13. Micro-bubbles of hydrogen gas generated in the cathode electrode is negatively charged, forming a fine bubble these charged hydrogen gas, ammonium ium ions produced by reduction of dissolved nitrogen gas in the water by the cathode electrolysis of the complex To do. It seems that the surface charge of the complex is reduced, it becomes easier to coalesce the complex, the fine bubbles of hydrogen gas coalesce into larger hydrogen gas bubbles, the hydrogen gas evaporates, and the dissolved hydrogen concentration decreases . FIG. 12 shows the effect of a combination of microbubbles of hydrogen gas and a cation charged body.

  When hydrogen gas is injected into water through a porous tube by the hydrogen gas injection method, depending on the material of the porous tube, the hydrogen gas microbubbles are generated by friction when passing through the porous tube. The surface is negatively charged. When negatively charged hydrogen gas microbubbles are generated in water with a large amount of impurity ions, impurity positive ions gather around the hydrogen gas microbubbles. As a result, the hydrogen gas fine bubbles are easily united and the dissolved hydrogen concentration is lowered.

It is what.

(1) Use a cation exchange resin that is an organic substance.
(2) Use zeolite, an inorganic substance that adsorbs cations.

  The water used as the raw material for the hydrogen water of the present invention preferably has a pH of 9.5 or less and 8.6 or less. Hydrogen water by cathode electrolysis becomes alkaline. When utilized as drinking water, the pH range is in the range of 5.5 to 8.6 according to the drinking water standard. For this reason, pH 8.6 or less is preferable. The soft drink itself has a more acidic range, but pH 3.5 or higher is desirable. Moreover, the suitable pH is set to 9.5 by the alkali ion water conditioner council. If the pH exceeds 9.5, it is not preferable because care is required for drinking. In view of these points, H is preferably 9.5 or less and 8.6 or less.

  The water used as the raw material for the hydrogen water of the present invention preferably has an electric conductivity of 100 μS / cm or less. When the conductivity exceeds 100 μS / cm, the impurity ion concentration in the raw water increases. Since the impurity ions include alkali metal and alkaline earth metal ions, the cathode electrolysis increases the risk that the pH of the hydrogen water, which is the cathode electrolyzed water, becomes more alkaline. This is not preferable.

The dissolved hydrogen concentration in the hydrogen water as the cathode electrolyzed water was measured using a conventional hydrogen water production apparatus that does not employ the positively charged body removing means downstream of the electrolytic cell as the hydrogen generating means. The size of the electrode incorporated in the electrolytic cell was 6 × 5 cm ² , the current was 2.5 A, and the flow rate was 0.4 l / min. The dissolved hydrogen concentration at that time was measured. For measurement of dissolved hydrogen concentration, KM2100DH manufactured by Kyoei Denshi Laboratories was used. This hydrogen concentration sensor was a diaphragm polaro system, and the hydrogen molecules that permeated through the diaphragm were measured by the polaro system. As a result, the dissolved hydrogen concentration was about 0.6 ppm. Therefore, the hydrogen water obtained by the hydrogen water production apparatus of the present invention has a dissolved hydrogen concentration of 0.6 ppm or more.

  An example of the hydrogen generating means used in the hydrogen water production apparatus of the present invention is an electrolytic cell.

  Moreover, as a hydrogen injection means used in the hydrogen water production apparatus of the present invention, there is a hydrogen gas injection method in which hydrogen gas is bubbled into water and hydrogen gas is dissolved in water. Hydrogen gas is supplied as fine bubbles through a porous membrane filter or a porous tube, and hydrogen gas is dissolved in water.

  The electrolytic cell used as the hydrogen generating means used in the hydrogen water production apparatus of the present invention is not particularly limited as long as hydrogen gas is generated from the cathode electrode by electrolysis of water.

  FIG. 2 shows a schematic diagram of a normal two-chamber electrolytic cell 3. The two-chamber electrolytic cell 3 is divided into a cathode chamber 5 containing a cathode electrode 4 and an anode chamber 8 containing an anode electrode 7 by a diaphragm 6 made of a fluorine-based cation exchange membrane. The raw water is catholyzed to produce hydrogen water in which hydrogen gas is dissolved.

  The electrolytic cell is not limited to the above-described ordinary two-chamber electrolytic cell, and as shown in FIG. 3, a porous cathode electrode 4 and a porous cathode are formed on both sides of a diaphragm 6 made of a fluorine-based cation exchange membrane. A two-chamber electrolytic cell having a structure in which the cathode electrode 7 is in close contact may be used. As shown in FIG. 5, the porous electrode is one in which a plurality of through holes 11 are provided in the electrode plate 10 to impart water permeability to the electrode plate. The openings (through holes) are preferably provided so as to average the water flow resistance as much as possible over the entire electrode plate, and are generally provided so as to be evenly distributed on the electrode plate. The size of the opening, the area ratio with respect to the entire electrode plate, and the like are not necessarily determined uniformly, but are determined according to the current density required for the apparatus, the performance of water resistance, and the like.

The two-chamber electrolytic cell having a structure in which porous electrode plates are closely attached to both surfaces of the diaphragm 6 as shown in FIG. 3 is intended to electrolyze water as high as possible as raw water. When the purity of the raw water increases, the conductivity of the raw water decreases, the electrolysis voltage increases, and electrolysis becomes difficult. In order to electrolyze raw water of high purity, it is desirable to use a fluorine-based cation exchange membrane. In this electrolytic cell, a fluorinated cation exchange membrane is used as a diaphragm, and an anode electrode and a cathode electrode are adhered to both sides thereof. In the fluorinated cation exchange membrane, an ion exchange group —SO ₃ H is bonded to the fluorinated molecular skeleton. In a fluorine-based molecular skeleton atmosphere, -SO ₃ ^- and H ⁺ are easily separated from each other, and the separated H ⁺ acts as a carrier.

^{_{2H 2 O - 4e - → O}} 2 + 4H + (4)

^{_{2H 2 O + 2e - → H}} 2 + 2OH - (5)

  Changes in pH due to electrolysis are also reduced, and in the case of drinking water, the pH is limited to 5.5 to 8.6, so a small change in pH is an advantage.

  Further, as shown in FIG. 4, a porous anode electrode 7 is brought into close contact with a diaphragm 6 made of a fluorine-based cation exchange membrane, and the porous cathode electrode 4 is separated from the porous cathode electrode 4 and the diaphragm 6. Alternatively, the two-chamber electrolytic cell 3 having a structure in which the ion exchange resin 9 is filled in the cathode chamber 5 provided with the above may be used.

The ion exchange resin includes a cation exchange resin that captures cations and an anion exchange resin that captures anions. As described above, nitrogen molecules are dissolved in the water for cathode electrolysis. When such a water cathode electrolysis, the compounds of the positive charge of the ammonium-ion is generated. In order to supplement these, a cation exchange resin is effective. In general, when cation exchange resin or anion exchange resin is used alone, the pH of water may shift to acidic or alkaline. Therefore, in order to suppress the pH change of water, cation exchange resin and anion exchange resin were mixed. In many cases, a mixed floor type is adopted.

  In order to electrolyze high-purity water, it is preferable to use a two-chamber electrolytic cell 1 having a structure in which the cathode chamber 5 is filled with an ion exchange resin 9 as shown in FIG.

  When electrolyzing high-purity water, electrolysis can be easily performed by energizing a porous (water-permeable) anode electrode and a cathode electrode in contact with both sides of a fluorine-based cation exchange membrane. However, since the electrolytic reaction occurs between the fluorine-based cation exchange membrane and the electrode, hydrogen gas is supplied to the cathode electrolyzed water through the holes of the cathode electrode of the porous chamber. The hydrogen gas was in the form of fine particles immediately after generation, but when passing through the porous cathode electrode, the fine particles coalesce into large particles. Since such hydrogen gas is volatilized in the air, the dissolved hydrogen concentration does not increase.

  In the electrolytic cell used in the present invention, an ion exchange resin is filled between the fluorine-based cation exchange membrane and the cathode electrode. Hydrogen ions, which are carriers generated at the anode electrode, reach the cathode electrode via the ion exchange resin, and electrolysis is possible. By using the electrolytic cell having this structure, it is possible to pass cathode electrolyzed water between the cathode electrode and the fluorine-based cation exchange membrane. Furthermore, as a result, the cathode electrolyzed water in which the generated fine hydrogen gas fine particles are dissolved is collected from the electrolytic cell.

  In the hydrogen water production apparatus of the present invention, a three-chamber electrolytic cell in which an intermediate chamber partitioned by a fluorine-based cation exchange membrane is provided between an anode chamber and a cathode chamber as an electrolytic cell for hydrogen generation means. May be.

  The structure of the three-chamber electrolytic cell is schematically shown in FIG. In the three-chamber electrolytic cell, a cathode chamber 5 and an anode chamber 8 are partitioned by a diaphragm 6 made of fluorine-based cation exchange, and an intermediate chamber 14 is formed. The cathode chamber 5 and the intermediate chamber 12 are filled with an ion exchange resin. The three-chamber electrolytic cell shown in FIG. 8 has the following advantages. When it is desired to control the pH of the cathode electrolyzed water, it is possible to easily prevent the cathode electrolyzed water from shifting to alkaline by adding an organic acid or the like to the intermediate chamber. Thus, it is possible to control the cathode electrolyzed water by controlling the intermediate chamber without controlling the raw water.

  As an apparatus for producing hydrogen water having a high dissolved hydrogen concentration, as shown in FIG. 10, an electrolytic cell in which hydrogen generation means and positive charge body removal means are integrated may be used. The electrolytic cell of the present embodiment is a two-chamber electrolytic cell in which the cathode chamber 5 is filled with an ion exchange resin 9 as a positive charge body removing means, but the total length of the cathode electrode 4 is in the longitudinal direction of the cathode chamber 5. It is shorter than the length and is arranged on the raw water inflow side. Therefore, the downstream portion of the cathode chamber has no cathode electrode and is filled with an ion exchange resin. By using an electrolytic cell having such a structure, positive charge bodies such as ammonium ions generated by cathode electrolysis are adsorbed and removed by the ion exchange resin in the downstream portion of the cathode chamber, and hydrogen water having a high dissolved hydrogen concentration can be produced. it can. By integrating the positive charge body removing means, the apparatus for producing hydrogen water having a high dissolved hydrogen concentration can be made compact.

  Hydrogen water was generated using a two-chamber electrolytic cell having the structure shown in FIGS. A system flow as shown in FIG. 6 was used. That is, raw material water is supplied to the cathode chamber 5 of the two-chamber electrolytic cell 3 and catholyzed at the cathode electrode 4, and hydrogen water flowing out from the cathode chamber 5 is passed through the ion exchange resin column 12 and stored in the water storage tank 13. It was.

As the cathode electrode or anode electrode, a water-permeable electrode having a large number of through holes as shown in FIG. 5 was used. The effective outer area of the electrolytic cell is 5 × 6 cm ² . Water having a conductivity of 8 μS / cm treated with a reverse osmosis membrane filter was used as raw water for the electrolytic cell. Raw water was supplied to the cathode chamber at 0.4 l / min. An electrolysis current of ² to 4 A / cm ² was applied. As the 4φ × 15 cm ion exchange resin column attached to the outlet side of the electrolytic cell, a mixed bed column in which a cation exchange resin and an anion exchange resin were mixed was used. The ratio of ion exchange resin was 2: 1 by volume.

  For measurement of dissolved hydrogen concentration, KM2100DH manufactured by Kyoei Denshi Laboratories was used. This hydrogen concentration sensor measures the hydrogen molecules that have passed through the diaphragm in a polaro manner. Table 1 shows the measurement results of the dissolved hydrogen concentration. As is clear from the results in Table 1, it has been clarified that the concentration of dissolved hydrogen is increased by disposing the ion exchange resin column downstream (outlet side) of the electrolytic cell.

Next, using a natural zeolite having the ability to adsorb cations ammonium um ions generated by electrolysis was confirmed dissolved hydrogen concentration increasing effect. Natural zeolite fine particles were packed in a 4φ × 15 cm ³ column. As the electrolytic cell, a three-chamber electrolytic cell shown in FIG. 8 was used. The system flow is shown in FIG. As shown in FIG. 9, the positive charge is removed from the hydrogen water flowing out from the cathode chamber 5 of the three-chamber electrolytic cell by the zeolite-filled column 18 and stored in the water storage tank 13. In the three-chamber electrolytic cell, an intermediate chamber 12 is provided between the anode chamber 8 and the cathode chamber 5 using a fluorine-based cation exchange membrane as a diaphragm. High-purity treated water equal to or higher than water obtained by filling the intermediate chamber 12 and the cathode chamber 5 with a cation exchange resin and performing reverse osmosis membrane filter treatment was supplied to the cathode chamber 5 and the intermediate chamber 12. High-purity treated water was circulated in the intermediate chamber 12 by an intermediate chamber liquid tank 19 and an intermediate chamber liquid circulation pump 20. As the anode electrode and cathode electrode having an effective electrolytic reaction outer area of 5 × 6 cm ² , a porous electrode having a large number of through holes as shown in FIG. 5 was used, and the electrolysis current was set to ² to 4 A / cm ² . The cathode chamber 5 was supplied with water subjected to reverse osmosis membrane filter treatment at 0.5 l / min. The intermediate chamber 12 was filled with an ascorbic acid aqueous solution (concentration 1%) and circulated to the intermediate chamber 12. The experimental results are shown in Table 2. As is clear from the results in Table 2, the dissolved hydrogen concentration increased by passing the hydrogen water flowing out from the electrolytic cell through the zeolite packed column. Thus, the effect of the present invention was clarified.

Next, as shown in FIG. 10, an electrolytic cell in which the hydrogen generation means and the positive charge body removal means were integrated was tested. The total length of the cathode electrode 4 is smaller than the length of the cathode chamber 5 in the longitudinal direction, and is installed on the raw material water inlet side. In the ion exchange resin-filled electrolytic cell having the structure shown in FIG. 10, a 5 × 6 cm ² porous electrode was used. The inner surface area of each chamber of the electrolytic cell is 6 × 12 cm ² . The cathode chamber 5 was filled with a mixed bed type ion exchange resin. As raw water, water subjected to reverse osmosis membrane filter treatment was used, and the electrolysis current was set to ² to 4 A / cm ² A. Table 3 shows the measurement results of the dissolved hydrogen concentration. Thus, the effect of the present invention was clarified.

  The dissolved hydrogen concentration was measured using a hydrogen gas injection method as a hydrogen injection means. FIG. 7 shows a system flow diagram. As shown in FIG. 7, while measuring the pressure from the hydrogen gas cylinder 15 with the pressure gauge 17, the injection pressure was controlled with the pressure reducing valve 16 for injection, and hydrogen gas was supplied through the hydrogen gas injection filter 18. Reverse osmosis membrane treated water was supplied at 0.5 l / min. A polyprene microfiltration membrane was used as a hydrogen gas injection filter.

The precision filter membrane was a porous filter (6.4Φ × 10.5 cm ² ) having an average diameter of 0.1 μm, and the injection pressure was 0.2 MPa. Hydrogen gas was injected into the reverse osmosis membrane filtered water. Table 4 shows the results of increasing the dissolved hydrogen concentration. Thus, the effect of the present invention was clarified.

  The blood pressure lowering action of hydrogen water produced by the apparatus of the present invention was examined.

  First, the systolic blood pressure before taking hydrogen water was measured. After ingesting 1 liter of hydrogen water (hydrogen water A) having a dissolved hydrogen concentration of 0.2 ppm produced using a system that uses only the two-chamber electrolytic cell of FIG. 2 and does not use an ion exchange resin column, Hypertension was measured. Next, after ingesting 1 l of 0.9 ppm hydrogen water (hydrogen water B) produced using the system incorporating the electrolytic cell and ion exchange resin column of FIG. 3 every three months, the systolic blood pressure was measured. The results are summarized in Table 5. As can be seen from Table 5, it can be seen that the blood pressure lowering effect is increased by ingesting the hydrogen water B having a high dissolved hydrogen concentration according to the present invention, as compared with the case in which the hydrogen water A having a low dissolved hydrogen concentration is ingested.

The blood glucose level lowering effect of the hydrogen water produced by the apparatus of the present invention was examined.
First, the blood glucose level before intake of hydrogen water was measured. After ingesting 1 liter of hydrogen water (hydrogen water A) having a dissolved hydrogen concentration of 0.2 ppm produced using a system that uses only the two-chamber electrolytic cell of FIG. 2 and does not use an ion exchange resin column, for 3 months, The value was measured. Subsequently, 0.9 ppm of hydrogen water (hydrogen water B) produced by using the system incorporating the electrolytic cell and ion exchange resin column of FIG. 3 was ingested daily for 1 month for 3 months, and then the blood glucose level was measured. The results are summarized in Table 6. As can be seen from Table 6, it is understood that the blood glucose level is further lowered by ingesting hydrogen water produced by the apparatus of the present invention and having a high dissolved hydrogen concentration.

  It was examined how LDL cholesterol and neutral fat were changed by ingesting hydrogen water produced by the apparatus of the present invention.

  First, the LDL cholesterol and triglyceride level of blood before ingesting hydrogen water were measured. After ingesting 1 liter of hydrogen water (hydrogen water A) having a dissolved hydrogen concentration of 0.2 ppm produced using a system that uses only the electrolytic cell of FIG. 2 and does not use an ion exchange resin column, for 3 months, blood LDL cholesterol And the triglyceride value was measured. In the next step, 1 l of hydrogen water (hydrogen water B) with a dissolved hydrogen concentration of 0.9 ppm produced using the system incorporating the electrolytic cell and ion exchange resin column of FIG. It was measured. The results are summarized in Table 7. As can be seen from Table 7, the effect of lowering LDL cholesterol and neutral fat level is greater by ingesting hydrogen water B having a high dissolved hydrogen concentration according to the present invention than when ingesting hydrogen water A having a low dissolved hydrogen concentration. I understand that.

Example 8
The flexibility of the blood vessels was examined using a BC checker manufactured by Future Wave Inc. The BC checker uses a waveform obtained by secondarily differentiating the pulse wave of the peripheral blood vessel. A to G are classified according to the waveform, the correlation between the age and the waveform is summarized, and the blood vessel age is determined from the measured value. Table 8 shows the correlation between the waveform for the BC checker and the age. Then, 1 to 2 liters of hydrogen water (pH: 5.5, ORP: -440 mV, dissolved hydrogen concentration: 0.2 ppm) generated by the hydrogen water production apparatus is drunk daily, and the blood vessel age when 3 months have passed is determined as a BC checker. I examined it. Thereafter, hydrogen water (pH: 6.1, ORP: −510 mV, dissolved hydrogen concentration: 0.9 ppm) produced by attaching the ion exchange resin column of the present invention to this hydrogen water production apparatus was ingested for 3 months. The results are shown in Table 9. The vascular rejuvenation rank changes in a better direction. Compared with the dissolved hydrogen concentration of 0.6 ppm, the difference in rank was larger when the dissolved hydrogen concentration was 1.0 ppm.

  From the results shown in Table 9, it is apparent that the blood vessel age rejuvenates more by drinking the high-concentration B hydrogen water produced using the present invention.

  The apparatus of the present invention makes it possible to produce hydrogen water having a high dissolved hydrogen concentration. Hydrogen water having a high dissolved hydrogen concentration can effectively scavenge active oxygen, and is useful for lowering blood pressure, blood glucose level, LDL cholesterol and neutral fat, and softening blood vessels.
