Description

  The present invention relates to a hydrogen water production apparatus, and more particularly to a hydrogen water production apparatus for easily producing hydrogen water that contains hydrogen and in which the contained hydrogen is difficult to scatter from water.

  Hydrogen water is water in which hydrogen is dissolved at a high concentration. In recent years, it has attracted attention as reducing and removing active oxygen in the human body, which is said to be harmful to human health, by drinking hydrogen water. ing. In addition to being used as a health drink, hydrogen water is also attracting attention for industrial uses such as cleaning semiconductor substrates in the semiconductor industry and cleaning scales in factory piping.

  Methods for producing hydrogen water can be broadly divided into a high-pressure dissolution method (for example, Patent Document 1) in which hydrogen gas is dissolved in water under high pressure, and water is put into an electrolytic cell of an electrolysis apparatus, and an anode and a cathode There is an electrolysis method (for example, Patent Document 2) in which hydrogen is generated on the cathode side by applying a voltage therebetween.

  However, a method of dissolving hydrogen gas in water under high pressure must use a high-pressure hydrogen gas cylinder that is a dangerous substance, and is not suitable as a method for easily producing hydrogen water in general households. . Therefore, as a method for easily producing hydrogen water, it is preferable to produce it by electrolysis of water.

Japanese Patent No. 3606466 JP 2002-254078 A

  However, hydrogen water produced by the high-pressure dissolution method of Patent Document 1 and the electrolysis method of Patent Document 2 is scattered in a short time in any case, and the effect as hydrogen water is reduced. There is a problem.

  The present invention has been made in view of such circumstances, and provides a hydrogen water production apparatus capable of easily producing hydrogen water in which hydrogen is dissolved at a high concentration and the dissolved hydrogen is less likely to scatter from the water. For the purpose.

  In order to achieve the above object, a hydrogen water production apparatus according to the present invention includes a water electrolysis apparatus for electrolyzing water to generate hydrogen and oxygen in the hydrogen water production apparatus for producing hydrogen water, and the electric water production apparatus. It comprises at least a nanobubble generator for generating at least the hydrogen nanobubbles of the hydrogen and the oxygen in the electrolyzed water produced by the decomposition.

  According to the hydrogen water production apparatus of the present invention, water is electrolyzed by a water electrolysis apparatus, oxygen is generated from the anode, and hydrogen is generated from the cathode. Then, hydrogen and oxygen nanobubbles generated by the electrolysis are generated in the electrolyzed water generated by the electrolysis by the nanobubble generator.

  Accordingly, it is possible to easily produce hydrogen water that dissolves in high concentrations of nanobubble hydrogen that easily dissolves in water and does not easily scatter from water, and in which dissolved hydrogen does not easily scatter from water. In addition, as water, pure water, tap water, mineral water, etc. can be used, for example.

  In the hydrogen water production apparatus of the present invention, the nanobubble generator stores the electrolyzed water and a liquid storage tank formed by a sealed pressure-resistant container, and hydrogen gas and oxygen gas generated by the electrolysis. It is preferable to include a gas release unit that discharges the electrolyzed water in the liquid storage tank at a high pressure, and an open / close valve that opens the liquid storage tank that has become a high pressure due to the release of the gas to atmospheric pressure.

Thereby, hydrogen gas and oxygen gas generated by electrolysis are released at high pressure from the gas release means into the electrolyzed water stored in the liquid storage tank. As a result, the hydrogen gas and oxygen gas high-speed air current is rubbed and sheared violently with the electrolyzed water, and nanobubbles are generated. Furthermore, nanobubbles are also generated when the liquid storage tank, which has become high pressure due to gas release, is opened to atmospheric pressure by the open / close valve.
Thus, hydrogen nanobubbles can be formed in two steps in a multi-step manner, so that it is possible to reliably produce hydrogen water that is dissolved at a high concentration and in which dissolved hydrogen is unlikely to scatter from water.

In the hydrogen water production apparatus of the present invention, it is preferable that the water electrolysis apparatus includes a gas ratio adjusting unit that adjusts a gas ratio of hydrogen gas and oxygen gas released into the electrolyzed water in the liquid storage tank.
Furthermore, the water electrolyzer has a liquid ratio of anode electrolyzed water (acidic water) that is electrolyzed water stored in the liquid storage tank and cathode electrolyzed water (alkaline ion water: also called alkaline water). It is preferable to provide a liquid ratio adjusting means for adjusting.
Thereby, hydrogen water which adjusted hydrogen concentration and oxygen concentration arbitrarily according to uses, such as a health use or an industrial use, can be manufactured. Moreover, the hydrogen water which adjusted the ratio of acidic water and alkaline water arbitrarily can be manufactured.

In the hydrogen water production apparatus of the present invention, it is preferable to provide a magnetic treatment apparatus that performs magnetic treatment by passing the water through a magnetic field in the previous stage of the water electrolysis apparatus.
As described above, by performing the magnetic treatment by passing water through the magnetic field, the water clusters are subdivided and the water is activated to be in a high energy state. And the water into which the cluster was subdivided and was in a high energy state has a high dissolving power.

  Therefore, the electrolyzed water produced by electrolyzing the magnetically treated water has a higher dissolving power than the electrolyzed water that is not magnetically treated, so that the hydrogen and oxygen nanobubbles are more easily dissolved in the electrolyzed water. Thereby, hydrogen water in which hydrogen is dissolved at a higher concentration can be produced, and the dissolved gas is more difficult to be scattered. In addition, magnetically treated water can enhance functions such as the ability to penetrate human cells and the like, and the ability to remove dirt, thereby further increasing the added value for health drinks and industrial applications. it can.

In the hydrogen water production apparatus of the present invention, the magnetic treatment device includes a magnetic treatment unit provided in a circulation path through which the water circulates, and a switching unit that causes the water circulated through the circulation path to flow to the water electrolysis apparatus. And preferably.
As described above, since water circulates and can pass through the magnetic processing section a plurality of times, a large charge can be generated in the water. Thereby, the property as magnetic water can be maintained for a long time. Since magnetic water is said to have effects such as promoting metabolism, the health value of hydrogen water can be improved by maintaining the properties of magnetic water for a long time.

In the hydrogen water production apparatus according to the present invention, the magnetic processing unit includes a plurality of magnets arranged along the circulation path, and the plurality of magnets are arranged so that the magnetic pole directions of the magnets are irregular. It is preferable that
In this way, by arranging the plurality of magnets so that the magnetic pole directions of the magnets become irregular, it is possible to generate a larger charge in the water.

In the hydrogen water production apparatus according to the present invention, the water electrolysis apparatus includes a plurality of titanium oxide electrodes constituting an anode and a cathode, a direct current power source for applying a voltage to the plurality of titanium oxide electrodes, and the plurality It is preferable to include ultraviolet irradiation means having an ultraviolet light guide for irradiating the titanium oxide electrode with ultraviolet light, and control means for switching and controlling the polarity of the plurality of titanium oxide electrodes.
As described above, by irradiating the titanium oxide electrode with ultraviolet rays from the ultraviolet light guide, oxygen and hydrogen can be generated by photolysis of water in addition to electrolysis of water.
Moreover, since the hydrophilicity of the electrode surface is increased by irradiating the titanium oxide electrode with ultraviolet rays, the generated hydrogen and oxygen are easily separated from the electrode.
In addition, when the titanium oxide electrode is irradiated with ultraviolet rays, the electrode is self-cleaning due to the increase in hydrophilicity of the electrode surface and the decomposition effect of the organic matter, so that the contamination of the electrode can be prevented.
Moreover, by switching the polarity of the titanium oxide electrode, it is possible to prevent the mineral component in the water from adhering to the electrode and degrading the electrolysis performance.
With these features, the hydrogen water production apparatus according to the present invention can increase the hydrogen generation efficiency as compared with the case of only electrolysis. Therefore, since hydrogen can be generated with high generation efficiency, the hydrogen water production apparatus can be made compact.

In the hydrogen water production apparatus of the present invention, the titanium oxide electrode includes Ti (titanium), TiO2 (titanium oxide), Ni (nickel), Fe (iron), Cr (chromium), Pt (platinum), and Co (cobalt). , Rh (rhodium) powder is preferably formed by powder metallurgy, and the ratio of TiO2 after sintering is preferably 3 to 5% by mass.
Thereby, hydrogen can be generated with higher generation efficiency.

In the hydrogen water production apparatus of the present invention, it is preferable that a cavity is formed inside the anode and cathode of the water electrolysis apparatus, and a magnet is provided in the cavity.
Thereby, since the magnetic treatment of water can be performed in parallel with the electrolysis of water in the water electrolysis apparatus, the apparatus can be made compact. In addition, the aspect which forms a cavity part in the inside of an electrode, and provides a magnet in this cavity part is applicable to both the case where a magnetic processing apparatus is further provided in the front | former stage of a water electrolysis apparatus, and the case where it does not provide.

In the hydrogen water generator of the present invention, the cathode of the water electrolyzer preferably contains SrTiO ₃ (strontium titanate).
Strontium titanate is included in the cathode for generating hydrogen, and the cathode is irradiated with ultraviolet rays of 400 to 800 nm by ultraviolet irradiation means. Thereby, hydrogen generation from the cathode can be promoted.

In the hydrogen water generator of the present invention, the anode of the water electrolyzer preferably contains WO ₃ (tungsten oxide).
Tungsten oxide is contained in the anode that generates oxygen, and the anode is irradiated with ultraviolet rays by the ultraviolet irradiation means. Thereby, oxygen generation from the anode can be promoted.

[First Embodiment]
FIG. 1 is an overall configuration diagram of a hydrogen water production apparatus 10 according to a first embodiment of the present invention.
As shown in FIG. 1, the hydrogen water production apparatus 10 of the first embodiment mainly includes a water electrolysis apparatus 12 that electrolyzes water to generate hydrogen and oxygen, and hydrogen and oxygen in the electrolysis water. And a nanobubble generator 14 that generates bubbles (generally called nanobubbles) having a diameter of 1 μm or less.

The water electrolyzer 12 mainly includes an electrolytic cell 16, two electrodes 18, 20 provided in the electrolytic cell 16, each composed of an anode 18 and a cathode 20, and electric wires 22 connected to the two electrodes 18, 20.

The raw water to be electrolyzed is supplied so as not to fill the electrolytic cell 16, and a head space portion 27 is formed in the upper part of the electrolytic cell 16.

  The electrolytic cell 16 is formed as a sealed container and is divided into an anode chamber 28 provided with an anode 18 and a cathode chamber 30 provided with a cathode 20. The anode chamber 28 and the cathode chamber 30 are connected to raw water by a communication chamber 32. Are communicated so that they can travel freely. In FIG. 1, the communication chamber 32 is provided at the bottom of the electrolytic cell 16, but is not limited to this position.

  Further, hydrogen gas and oxygen gas generated by electrolysis of raw water on the ceiling surfaces of the anode chamber 28 and the cathode chamber 30 and accumulated in the head space portions 27A and 27B of the anode chamber 28 and the cathode chamber 30, respectively. Gas discharge ports 34 </ b> A and 34 </ b> B for discharging the gas from the electrolytic cell 16 are formed.

  The gas discharge ports 34A and 34B of the anode chamber 28 and the cathode chamber 30 are connected to an air supply pipe 36 that sends the gas generated in the water electrolysis device 12 to the nanobubble generator 14. In the air supply pipe 36, two gas pipes extending from the gas discharge ports 34A and 34B merge into one, and a first three-way cock 38 as a gas ratio adjusting means is provided at the merge portion. The first three-way cock 38 can change the gas ratio of hydrogen gas to oxygen gas fed to the nanobubble generator 14.

  In addition, anode electrolytic water, which is electrolyzed water generated in the anode chamber 28 and the cathode chamber 30 by electrolysis of raw water, is provided below the anode chamber 28 and the cathode chamber 30 (portion below the water surface). Liquid discharge ports 40A and 40B for discharging the cathode electrolysis water are formed, respectively.

  A liquid feed pipe 42 for sending electrolyzed water to the nanobubble generator 14 is connected to the liquid discharge ports 40A and 40B of the anode chamber 28 and the cathode chamber 30, respectively. In the liquid feeding pipe 42, two liquid pipes extending from the liquid discharge ports 40A and 40B of the anode chamber 28 and the cathode chamber 30 merge into one, and the ratio of electrolyzed water is adjusted at the merged portion. A second three-way cock 44 is provided as a means. By this second three-way cock 44, the liquid ratio of the anodic electrolyzed water and the cathodic electrolyzed water fed to the nanobubble generator 14 can be changed.

The electrodes of the anode 18 and the cathode 20 used in the present embodiment are formed in a long rod shape, and it is preferable to use a titanium oxide electrode.
The titanium oxide electrode is made of, for example, powders of Ti (titanium), TiO2 (titanium oxide), Ni (nickel), Fe (iron), Cr (chromium), Pt (platinum), Co (cobalt), and Rh (rhodium). It can also be formed by powder metallurgy, and Ti (titanium) and TiO2 (titanium oxide) can be formed by powder metallurgy around an electrode core formed of a stainless steel rod. As for the mass ratio of each metal after sintering performed by powder metallurgy, the ratio of TiO2 is preferably 3 to 5 mass% of the whole. Thereby, the effect based on the various TiO2 mentioned later is fully exhibited. In addition, it is more preferable to include platinum group elements such as Pt (platinum) and Rh (rhodium) and Co (cobalt) because the decomposition of water can be promoted.

  Moreover, when the ratio of Ti and TiO2 is seen in the part formed by powder metallurgy, it is preferable to contain so that Ti concentration may become 5-7 mass% and TiO2 density | concentration will be 3-5 mass%. Thus, by forming the surfaces of the titanium oxide electrodes 18 and 20 with a porous sintered metal layer, the electrode surface area can be increased and the contact area with the water to be electrolyzed can be increased. In addition, the amount of titanium oxide present on the electrode surface can be increased. Thereby, the electrolysis efficiency of water and the photolysis efficiency of water can be improved.

  The nanobubble generator 14 is mainly composed of a liquid storage tank 46 that stores electrolyzed water of anode electrolyzed water and cathode electrolyzed water generated by electrolysis, and liquid hydrogen gas and oxygen gas generated by electrolysis. The gas discharge means 48 discharge | releases at high pressure in the electrolyzed water in the storage tank 46, and the opening-and-closing valve 55A which open | releases the liquid storage tank 46 which became high pressure by discharge | release of gas to atmospheric pressure.

  The air supply pipe 36 from the water electrolysis apparatus 12 is connected to the gas discharge means 48, and the liquid supply pipe 42 from the water electrolysis apparatus 12 is connected to the liquid storage tank 46. Further, a discharge pipe 50 is disposed from the gas discharge means 48 so as to be submerged in the electrolyzed water stored in the liquid storage tank 46, and a tapered nozzle 52 is provided at the tip of the discharge pipe 50. Thereby, the gas generated in the water electrolyzer 12 can be released into the electrolyzed water stored in the liquid storage tank 46 at a high pressure. As the gas discharge means 48, for example, a compressor can be used.

  In addition, the liquid storage tank 46 is formed as a hermetic pressure-resistant container, and an extraction pipe 54 with an opening / closing valve 54 </ b> A for extracting the produced hydrogen water is provided below the liquid storage tank 46. Further, a vent pipe 55 with an opening / closing valve 55 </ b> A for releasing the pressure in the liquid storage tank 46 is provided on the upper part of the liquid storage tank 46. In FIG. 1, the take-out pipe 54 and the vent pipe 55 are provided separately, but the vent pipe 55 may be shared by the take-out pipe 54.

FIG. 2 shows a preferred embodiment of the water electrolysis apparatus 12, in which an ultraviolet irradiation means 58 for irradiating the anode 18 and the cathode 20 with ultraviolet rays is provided.
The ultraviolet irradiation means 58 mainly includes a light emitting source 60 that emits ultraviolet light, ultraviolet light guiding paths 62 and 62 provided in the vicinity of the electrodes of the anode 18 and the cathode 20, and ultraviolet light emitted from the light emitting source 60. And a light guide wire 63 led to 62. As the light source 60, a UV-LED (ultraviolet LED) can be preferably used.

  As the ultraviolet light guide path 62, a U-shaped rod-like body can be suitably used, and is provided so as to surround the anode 18 (or the cathode 20) as shown in FIG. The ultraviolet light guide path 62 may be made of a resin or glass rod or tube that can transmit ultraviolet light. An anti-twist plate 64 for preventing the ultraviolet light guide 62 from being twisted is provided at the tip (U-shaped portion) of the ultraviolet light guide 62.

  In addition, for example, a visible light LED is used as a pilot LED so that ultraviolet light emission can be visually confirmed. When ultraviolet light is emitted from the light emission source 60, the ultraviolet light guide 62 is simultaneously illuminated by the visible light LED. It is preferable to make it. Since the wavelength region of the ultraviolet light emitted from the light emitting source 60 is in the range of 10 to 400 nm, the emission color of the visible light LED is more preferably a blue wavelength around 400 nm that makes it easy for the user to imagine the emission of ultraviolet light.

  By making the visible light LED an LED capable of emitting multiple colors, for example, the normal operating state is blue, the state of remaining battery power is orange, the current is stopped to the titanium oxide electrode due to overcurrent, etc. It is even more preferable because the operating state of the apparatus can be displayed more finely by the light emission color of the visible light LED, such as setting red to red.

As described above, in the embodiment of the water electrolysis apparatus 12 provided with the ultraviolet irradiation means 58 for irradiating the anode 18 and the cathode 20 with ultraviolet rays, the cathode 20 contains SrTiO ₃ (strontium titanate), and the anode 18 contains WO _3. (Tungsten oxide) is preferably included.

  Hydrogen generation from the cathode 20 can be promoted by adding strontium titanate to the cathode 20 for generating hydrogen and irradiating the ultraviolet irradiation means 58 with ultraviolet rays of 400 to 800 nm. In addition, tungsten oxide is included in the anode 18 that generates oxygen, and ultraviolet rays are irradiated by the ultraviolet irradiation means 58. Thereby, oxygen generation from the anode 18 can be promoted.

  Also in this case, by forming the surface of the titanium oxide electrode 16 with a porous sintered metal layer, the electrode surface area can be increased, and the amount of strontium titanate and the amount of tungsten oxide present on the electrode surface can be increased. When it is preferable that the amount of oxygen produced by the hydrogen water production apparatus 10 is small, the anode 18 does not need to contain tungsten oxide.

In addition, as shown in FIG. 2, it is preferable to provide a control means 66 for switching and controlling the polarities of the two electrodes 18 and 20.
The control means 66 mainly performs switching control for switching the polarities of the two electrodes 18, 20, switching timing control, continuous operation time control of the water electrolysis apparatus 12, current stop control during overcurrent, and the like. Yes, an IC chip can be suitably used. Thus, by switching the polarities of the two electrodes 18 and 20, it is possible to prevent the mineral components in the water from adhering to the electrodes during the electrolysis of water and degrading the electrolysis performance. Although the polarity switching timing varies depending on the mineral component concentration of water, it is generally preferable to switch at intervals of 2 to 15 seconds. Moreover, as control of continuous operation time, if the hydrogen water manufacturing apparatus 10 is operated for 30 seconds, for example, the power supply of the hydrogen water manufacturing apparatus 10 can be turned off.

  Next, a method for producing hydrogen water from tap water using the hydrogen water producing apparatus 10 of the first embodiment configured as described above will be described. The description will be made in the case where a titanium oxide electrode is used as the electrodes 18 and 20 and an ultraviolet irradiation means 58 is provided.

First, the operation of the water electrolyzer 12 will be described.
Tap water is supplied into the electrolytic cell 16 from the raw water supply pipe 26. Thereby, the two titanium oxide electrodes 18 and 20 and the ultraviolet light guide 62 are submerged in tap water.
Next, a power switch (not shown) of the hydrogen water production apparatus 10 is pressed to turn on the power, and a voltage is applied to the two titanium oxide electrodes 18 and 20, and two titanium oxide electrodes are connected from the ultraviolet light guide 62. 18 and 20 are irradiated with ultraviolet rays.

  Thus, oxygen is generated from the anode titanium oxide electrode 18 and hydrogen is generated from the cathode titanium oxide electrode 20 by water electrolysis. Furthermore, by irradiating the two electrodes 18 and 20 with ultraviolet rays from the ultraviolet light guide 62, oxygen and hydrogen are generated by photolysis of water (Honda-Fujishima effect) and negative ions are generated.

A part of the oxygen generated from the titanium oxide electrode 18 of the anode accumulates in the head space portion 27A of the anode chamber 28 as a gas, and the rest dissolves in the raw water and accumulates in the anode chamber 28 as anode electrolysis water. Similarly, part of the hydrogen generated from the cathode titanium oxide electrode 20 is accumulated in the head space portion 27B of the cathode chamber 30 as a gas, and the rest is dissolved in raw water and accumulated in the cathode chamber 30 as anode electrolysis water.
Then, the hydrogen gas and oxygen gas generated by the water electrolyzer 12 and the generated anode electrolyzed water and cathode electrolyzed water are processed by the nanobubble generator 14 which is the next step.

Next, the operation of the nanobubble generator 14 will be described.
The gas of hydrogen gas and oxygen gas generated in the water electrolyzer 12 is sent to the gas discharge means 48 of the nanobubble generator 14. In this case, the first three-way cock 38 can arbitrarily adjust the gas ratio of hydrogen gas to oxygen gas fed to the gas discharge means 48 according to the application.

  On the other hand, the electrolyzed water of the anode electrolyzed water and the cathode electrolyzed water generated by the water electrolyzer 12 is sent to the liquid storage tank 46 of the nanobubble generator 14 and stored. In this case, the liquid ratio of the anode electrolyzed water and the cathode electrolyzed water sent to the liquid storage tank 46 can be arbitrarily adjusted by the second three-way cock 44 according to the application.

  Then, hydrogen gas and oxygen gas are pressurized by the gas discharge means 48, and the pressurized gas is discharged from the nozzle 52 into the electrolyzed water stored in the liquid storage tank 46 at a high pressure. As a result, the high-speed gas stream of hydrogen gas and oxygen gas released at high pressure is rubbed violently with electrolyzed water and sheared, generating nanobubbles.

Next, when the release of gas from the gas release means 48 to the liquid storage tank 46 is completed, the open / close valve 55A of the vent pipe 55 is opened at once. As a result, the pressure of the liquid storage tank 46 whose internal pressure has been increased by the gas discharged from the gas discharge means 48 is released to atmospheric pressure all at once. By releasing the pressure, nano bubbles are further generated in the liquid storage tank 46.
Thereby, according to the hydrogen water production apparatus 10 of the first embodiment, hydrogen water can be easily produced in which hydrogen is dissolved at a high concentration and the dissolved hydrogen is hardly scattered from the water.

Then, the characteristics of the hydrogen water production apparatus 10 of the first embodiment described above are summarized as follows.
(A) Since the water electrolysis apparatus 12 performs both hydrogen generation by electrolysis and hydrogen generation by photolysis in parallel, the hydrogen generation efficiency is higher than in the case of only electrolysis.

  (B) By irradiating the titanium oxide electrodes 18 and 20 with ultraviolet rays, the hydrophilicity of the electrode surface is increased, so that the generated hydrogen and oxygen are easily separated from the titanium oxide electrodes 18 and 20. This prevents a reduction in electrolytic performance due to oxygen and hydrogen bubbles adhering to the titanium oxide electrodes 18 and 20, thereby further increasing the hydrogen generation efficiency. Then, since the generated hydrogen and oxygen are easily separated from the two titanium oxide electrodes 18 and 20, it is easy to form small bubble hydrogen, so that hydrogen is easily dissolved in water.

  (C) When the two titanium oxide electrodes 18 and 20 are irradiated with ultraviolet rays, the hydrophilicity of the electrode surface increases, so that the water is wet from under the dirt on the electrode surface to remove the dirt and adhere to the electrode surface. The self-cleaning effect that decomposes dirt such as organic matter can be exhibited. Thereby, since the electrode surface can be kept normal, hydrogen generation efficiency can be maintained in a high state.

(D) As a secondary effect of ultraviolet irradiation, water can be sterilized.
(E) When the control means 66 is used in combination, by switching the polarities of the two titanium oxide electrodes 18 and 20, the mineral component in the water adheres to the two titanium oxide electrodes 18 and 20 and the electrolytic performance is improved. It can be prevented from lowering. However, when the gas ratio adjustment and the liquid ratio adjustment described above are performed using the first three-way cock 38 and the second three-way cock 44, oxygen is generated in the anode chamber 28 and the cathode chamber 30 Since it is necessary to generate hydrogen, the control means 66 is stopped.

  (F) In the nanobubble generator 14, the generation of nanobubbles by discharging the gas generated in the water electrolysis apparatus 12 to the electrolyzed water in the liquid storage tank 46 at a high speed, and the liquid storage in a high pressure state due to the gas release. Both the generation of nanobubbles by opening the tank 46 to atmospheric pressure was performed. Thereby, nanobubbles can be generated efficiently.

  (G) The first three-way cock 38 that adjusts the gas ratio of hydrogen gas and oxygen gas generated by electrolysis and discharged into the electrolyzed water in the liquid storage tank 46, and the liquid storage tank generated by electrolysis Since the second three-way cock 44 for adjusting the ratio of the electrolyzed water of the anode electrolyzed water and the cathode electrolyzed water stored in 46 is provided, hydrogen is used depending on the use such as health use or industrial use. Hydrogen water in which the concentration and the oxygen concentration are arbitrarily adjusted and the acidity and alkalinity are arbitrarily adjusted can be produced.

Due to such characteristics, it is possible to easily produce hydrogen water that is unconventional in that hydrogen is dissolved at a high concentration and the dissolved hydrogen is difficult to scatter from the water.
Actually, the hydrogen water produced by the hydrogen water production apparatus 10 of the first embodiment was put into a cylindrical beaker, and the state of scattering of hydrogen from the hydrogen water was examined in a stationary state. As a result, even after 3 hours of standing, the scattering of hydrogen is only 30% of the total, and 70% of the hydrogen remains in the hydrogen water, and the scattering rate is higher than that of hydrogen water produced only by the water electrolyzer. It was possible to greatly reduce.

  In addition, when using the hydrogen water manufactured with the hydrogen water manufacturing apparatus 10 of this invention for drinks, oxygen is contained in addition to hydrogen, but there is no health problem even if drinking water in which oxygen is dissolved. It is also possible to produce hydrogen water containing almost no oxygen by adjusting the first three-way cock and the second three-way cock. Moreover, although the water electrolyzer 12 is illustrated as one unit in FIG. 1, hydrogen water can be produced more efficiently by arranging a plurality of water electrolyzers 12 in parallel and using them simultaneously. Is possible.

Is used. That is, all the magnetic poles of the arranged permanent magnets 82 are arranged so as to be parallel to the flow path direction, and the lines of magnetic force forming the magnetic field are generated parallel to the flow path direction. FIG. 4A shows a case where the N pole and the S pole are regularly arranged so that they are arranged in order. FIG. 4B shows the N pole and S of the adjacent permanent magnet 82. This is a case where the magnetic poles are arranged irregularly so that the magnetic poles are the same.

  In FIG. 4C, a cylindrical permanent magnet 82 having N poles and S poles separated in the radial direction is divided in half in the radial direction, and the permanent magnets 82 are opposed so that the magnetization pattern is reversed across the flow path 86. It is arranged. In this case, the N pole and the S pole are formed on the outer peripheral surface side and the inner peripheral surface side of the half-divided permanent magnet 82. That is, all the magnetic poles of the arranged permanent magnets 82 are arranged so as to be perpendicular to the flow path direction of the raw water, and the magnetic field lines forming the magnetic field are generated perpendicular to the flow path direction. In FIG. 4C, the magnetic poles on the outer peripheral surface side and the inner peripheral circular side of the permanent magnet 82 arranged opposite to each other with the flow path 86 therebetween are made different from each other.

FIG. 5 shows still another aspect of the magnetic processing unit 74, in which the magnetic processing unit 74 in FIG. 4B and the magnetic processing unit 74 in FIG. 4C are arranged in series.
As for the direction of the magnetic poles (N pole, S pole) of the permanent magnet 82 with respect to the raw water flowing through the flow path 86 of the magnetic processing unit 74, as shown in FIG. It is preferable to arrange irregularly like B), FIG. 4 (C), and FIG. By arranging them irregularly, a magnetic force can be applied to the raw water flowing through the flow path 86 without any bias, so that the raw water can be reliably magnetically treated.

The magnetic force of the permanent magnet 82 in the magnetic processing unit 74 is preferably about 1200 to 1700 gauss at the central axis position of the flow path 86.
Next, the operation of the magnetic processing device 68 configured as described above will be described using an example in which tap water is used as raw water.

  The tap water supplied from the raw water supply pipe 72 to the circulation pipe 70 forms a large water molecule group by hydrogen bonding. Also, ions contained in tap water, such as calcium ions (Ca 2+), sodium ions (Na +), and chlorine ions (Cl −), are surrounded by a large water-bonded water molecule group, Exists as a cluster.

  The tap water containing such clusters flows through the magnetic processing unit 74 and is magnetically processed, so that hydrogen bonds are broken. As a result, the clusters are refined and the tap water is ionized. In addition, water molecules are activated by magnetic treatment and become a high energy state. The tap water (magnetic water) in which such a cluster is reduced to a high energy state has a high dissolving power.

  Therefore, water that has been magnetically processed by the magnetic processing device 68 is electrolyzed by the water electrolysis device 12 to highly soluble electrolysis water, and hydrogen gas and oxygen gas at the nanobubble generator 14 at high pressure. Since the hydrogen gas is released, hydrogen water in which hydrogen is dissolved at a higher concentration can be produced, and the dissolved gas is less likely to be scattered.

  Further, in the magnetic treatment device 68, tap water can circulate through the circulation flow path 70 and pass through the magnetic treatment unit 74 a plurality of times, so that a large charge can be generated in the tap water. Further, by arranging the permanent magnets in the magnetic processing unit 74 irregularly, a larger charge can be generated in the tap water.

Thereby, the property as magnetic water can be maintained for a long time. Since magnetic water is said to have effects such as promoting metabolism, the health value of hydrogen water can be improved by maintaining the properties of magnetic water for a long time.
Magnetic water discharges over time, and the properties as magnetic water are reduced. However, the tap water magnetically processed by the magnetic processing device 68 of the present embodiment can maintain the properties as magnetic water for 24 hours, and is significantly longer than the magnetic water commercially available in the past.

  Therefore, according to the hydrogen water production apparatus 10 of the second embodiment of the present invention, the produced hydrogen water can be provided with a function as magnetic water, so that the value as health drinking water can only be improved. In addition, the value for industrial use can be improved.

  For example, when used as health drinking water, the concentration of chlorine dissolved in tap water by magnetic treatment can be reduced by 30% or more. Therefore, 90% or more of trihalomethane, which is a byproduct of chlorine, and tetrachlorethylene, which is considered difficult to process, can be removed. Moreover, since a large water molecule group can be made into a small water molecule group as mentioned above, the taste of the produced hydrogen water can be mellow.

Further, when looking at industrial applications, hydrogen water is used as washing water to remove scale (scale) in the pipe, and the oxidation of the pipe is prevented by utilizing the reduction action of hydrogen. In this case, how to dissolve the hydrogen having a low solubility at a high concentration is important for improving the detergency. If the hydrogen water production apparatus 10 of the second embodiment is used, the hydrogen generated in the water electrolysis apparatus 12 can be contained in tap water at a high concentration by the magnetic treatment apparatus 68 and the nanobubble generation apparatus 14. . Accordingly, the hydrogen water produced by the hydrogen water production apparatus 10 of the second embodiment is excellent for industrial use.
As other uses, the amount of detergent used can be reduced by using as water for a washing machine, and the growth of plants can be promoted by using as water for plant cultivation.

[Third Embodiment]
In the third embodiment of the hydrogen water production apparatus 10 according to the present invention, the water electrolysis apparatus 12 is configured so that the magnetic treatment and electrolysis of raw water are performed together in one apparatus.

As shown in FIG. 6, a cavity was formed inside the titanium oxide electrodes 18 and 20, and a permanent magnet 92 was provided in the cavity. Note that the magnetic processing device 68 described in the second embodiment may be arranged in the preceding stage of the water electrolysis device 12 in the third embodiment.
In addition, the aspect which forms a cavity part in the inside of the titanium oxide electrodes 18 and 20, and provides the permanent magnet 92 in this cavity part has the case where the magnetic processing apparatus 68 is further provided in the front | former stage of the water electrolysis apparatus 12, and is not provided. It can be applied to any of the above.

  Therefore, when the magnetic treatment device 68 is further provided in the previous stage of the water electrolysis device 12, the magnetic treatment of the raw water can be performed in multiple stages by the magnetic treatment device 68 and the water electrolysis device 12, so that the hydrogen is further increased. It is possible to produce hydrogen water which is dissolved in the concentration and in which the dissolved hydrogen is more difficult to scatter from the water.
