However, in this method, dangerous gas phase ozone may be released during heating. As another method, there is a method in which raw water heated to a desired temperature is prepared, and this is converted into ozone water by an electrolytic ozone water production apparatus.

In addition, this invention is not limited only to the form drawn on the figure. The scope of the present invention includes modifications, additions, or omissions of the respective parts within the scope of the present invention.

  The radical oxygen water supply device according to an embodiment of the present invention includes a raw water supply unit (11), an electrolyte supply unit (10), an electrolysis unit, and a temperature adjustment unit.

  The electrolysis part comprises a solid electrolyte membrane (8), an anode part (A), a cathode part (C), an electrolysis cell (1), means for applying a voltage between the cathode part and the anode part, And means for increasing the pressure in the electrolysis cell as necessary. A solid electrolyte membrane, an anode part, and a cathode part are accommodated in the electrolytic cell (1).

  The raw material water supply section (11) is not particularly limited as long as it can supply raw water to the electrolysis cell (1). The raw water supply unit (11) usually has a water source, a pump, and piping. As the raw water, fresh water such as tap water, river lake water, and groundwater can be used. Among these, tap water is preferable from the viewpoint of safety and hygiene and convenience. The water source may be one in which a tank is provided in the radical oxygen water supply device and raw water is stored in the tank, or the raw water is supplied to the radical oxygen water supply device from a water supply facility by a hose or the like. It may be what you did.

  A filter, a sedimentation tank, etc. can be provided in the middle of the piping in the raw water supply unit (11) to remove impurities and suspended matters. Examples of the filter include a cation exchange resin filter, an anion exchange resin filter, an activated carbon filter, and a calcium sulfite filter. When a cation exchange resin filter is used, for example, minerals such as calcium and magnesium can be removed from the raw water. Minerals may stick to the electrode and cause the electrode to deteriorate.

The electrolytic solution supply unit (10) is not particularly limited as long as it can supply the electrolytic solution to the electrolytic cell (1). The electrolytic solution supply unit (10) usually includes an electrolytic solution preparation unit, a pump, and piping.
The electrolytic solution can be prepared by dissolving an electrolyte compound or a high concentration electrolytic solution in fresh water or diluting with fresh water. The high concentration electrolytic solution may be diluted with fresh water before entering the electrolytic cell (1), or may be diluted in the electrolytic cell (1). As a method of diluting in the electrolytic cell, for example, between the solid electrolyte membrane (8) accommodated in the electrolytic cell and the cathode part (C) or between the dielectric layer (9) and the cathode part (C). The porous membrane (22) is provided as a partition, fresh water is supplied to the cathode portion (C) side of the porous membrane, and a high concentration electrolyte is supplied to the solid electrolyte membrane (8) side of the porous membrane, The electrolyte solution concentration in the cathode part can be set to a predetermined value by allowing the high-concentration electrolyte solution to penetrate into the cathode part (C) through the porous membrane (FIG. 2). If it does in this way, the efficiency of electrolysis can be raised and degradation of a cathode part can be controlled. In addition, the fresh water used for dilution may be supplied by an original supply means, or a part of the raw water supplied from the raw water supply unit may be divided and supplied. For example, a porous fluororesin film (such as an omnipore film) is used for the porous film (22).

  As the electrolyte compound, alkali metal chlorides such as NaCl, KCl, LiCl, hydrogen chloride, or hydrochloric acid are preferably used. In addition, the electrolytic solution used has a chloride ion concentration of preferably 10 mg / L or more and a saturation concentration, more preferably 50 mg / L or more and a saturation concentration or less, and further preferably 100 mg / L or more and a saturation concentration or less. When the chlorine ion concentration is high, the oxidative deterioration of the anode layer is suppressed and the current efficiency is maintained high.

  Moreover, in order to improve electrical conductivity, you may add another electrolyte material to electrolyte solution. For example, a material that generates nitrate ions or sulfate ions can be used. Examples of such materials include nitric acid, sulfuric acid, sodium nitrate, or sodium sulfate. Furthermore, in order to stabilize the pH of the electrolytic solution, the electrolytic solution may be a buffer solution. For example, by adding boric acid + sodium borate, phosphoric acid + sodium phosphate, acetic acid + sodium acetate, or citric acid + sodium citrate to an aqueous solution of NaCl, the electrolyte can be used as a buffer solution. The electrolytic solution may contain halogen ions other than chlorine ions, but the concentration is preferably 10 mg / L or less. Addition of an acid that forms a metal complex to the electrolytic solution is preferable because it can suppress the deposition of a substance on the surface of the cathode portion. Examples of the acid that forms the metal complex include organic acids such as acetic acid, citric acid, and ascorbic acid. The electrolytic solution may be circulated as described later. In such a case, it is preferable to contain an algaeproofing agent, a disinfectant, etc. in electrolyte solution. Moreover, the radical oxygen water produced | generated by the anode part can also be supplied to a cathode part, and a cathode part can also be cleaned.

  The solid electrolyte membrane (8) is installed between the anode part and the cathode part in the electrolytic cell. An anode portion is disposed on the first surface side of the solid electrolyte membrane, and a cathode portion is disposed on the second surface side of the solid electrolyte membrane. As the solid electrolyte membrane, a proton conductive film (H-type ion exchange membrane) is preferably used. Examples of the proton conductive film include a sulfonic acid type strongly acidic cation exchange resin and a perfluorosulfonic acid polymer film. As a commercial product, a Nafion membrane (registered trademark: manufactured by DuPont) can be exemplified. The thickness of the solid electrolyte membrane is preferably 0.05 to 0.5 mm, more preferably 0.1 to 0.3 mm. The end of the solid electrolyte membrane is in close contact with the inner wall of the electrolysis cell, blocking between the anode side and the cathode side, and only the exchange of ions and electrons through the solid electrolyte membrane is between the anode and cathode. It is preferable to be performed in the above.

  The anode part (A) is installed on the first surface side of the solid electrolyte membrane between the raw water inlet of the electrolytic cell and the radical oxygen water outlet. The anode part preferably has an anode electrode (5) and an anode layer. The anode electrode is a portion connected to the anode of the DC power supply, and is composed of a conductive plate such as titanium, for example. The anode layer is preferably composed of a conductive porous body, a conductive network or a conductive fiber assembly. The raw water can pass through voids in the anode layer (for example, pores in the porous body, meshes or fiber gaps). Bubbles (mainly oxygen or ozone) that may be generated by electrolysis can be dissolved in the raw water while passing through the complex shaped voids. For the anode layer, for example, a titanium mesh or a platinum mesh is used. As the titanium mesh, those having a wire diameter of 0.4 to 0.6 mmφ and a mesh size of 30 to 70 are preferably used. As the platinum mesh, those having a wire diameter of 0.05 to 0.1 mmφ and a mesh size of 60 to 100 are preferably used. The anode layer is placed in contact with the anode electrode, and direct current electricity is transmitted to the anode layer through the anode electrode. The anode layer is disposed in contact with the solid electrolyte membrane (8). The anode layer preferably has a mesh size on the anode electrode side smaller than the mesh size on the solid electrolyte membrane side. In the apparatus shown in FIG. 1, a first anode layer (7) made of platinum mesh, a second anode layer (6) made of titanium mesh, and an anode electrode (5) made of titanium are installed in the anode portion.

  The cathode part (C) is disposed between the electrolyte solution inlet and the electrolyte outlet of the electrolytic cell on the second surface side of the solid electrolyte membrane. The cathode part preferably has a cathode electrode (4) and a cathode layer. The cathode electrode is a portion connected to the cathode of the DC power supply, and is made of a conductive plate such as stainless steel, for example. In order to escape bubbles (mainly hydrogen) that may be generated by electrolysis, a groove may be formed on the cathode layer side surface of the cathode electrode, or a through hole may be formed in the cathode electrode. Good. The cathode layer is preferably composed of a conductive porous body, a conductive network, or a conductive fiber assembly. The electrolytic solution can pass through voids in the cathode layer (for example, pores of a porous body, meshes or fiber gaps). Bubbles that may be generated by electrolysis can be dissolved in the electrolyte while passing through a complex shaped gap. For the cathode layer, for example, a stainless steel mesh or a platinum mesh is used. As the stainless steel mesh, those having a wire diameter of 0.4 to 0.6 mmφ and a mesh size of 30 to 70 are preferably used. As the platinum mesh, those having a wire diameter of 0.05 to 0.1 mmφ and a mesh size of 60 to 100 are preferably used. The cathode layer is placed in contact with the cathode electrode, and direct current electricity is transmitted to the cathode layer through the cathode electrode. The cathode layer preferably has a mesh size on the cathode electrode side smaller than that on the solid electrolyte membrane side. In the apparatus shown in FIG. 1, the cathode part is provided with a first cathode layer (2) made of platinum mesh, a second cathode layer (3) made of stainless steel mesh, and a cathode electrode (4) made of stainless steel. .

  The cathode layer is preferably disposed so as not to contact the solid electrolyte membrane (8). As the distance d between the cathode layer and the solid electrolyte membrane increases, the deterioration of the solid electrolyte membrane decreases, but the power loss tends to increase. Therefore, the lower limit of the distance d is preferably a distance that produces a potential difference that is 1/10 times the potential difference ΔV that occurs between the cathode side and the anode side of the solid electrolyte membrane. The upper limit of the distance d is preferably a distance at which a potential difference of four times the potential difference ΔV generated between the cathode portion side and the anode portion side of the solid electrolyte membrane is generated.

  For example, when a sodium chloride aqueous solution having a concentration of 10% by mass (conductivity 121 mS / cm) is used as the electrolyte and a Nafion membrane (registered trademark: manufactured by DuPont) is used as the solid electrolyte membrane, the distance between the cathode layer and the solid electrolyte membrane d can be 0.1 to 4 times the thickness of the Nafion film. The conductivity of the Nafion membrane is about the same as that of a sodium chloride aqueous solution having a concentration of 10% by mass.

  A dielectric layer (9) can be provided between the cathode layer and the solid electrolyte membrane. The dielectric layer is made of, for example, a nonconductive porous body, a nonconductive network, or a nonconductive fiber assembly. The electrolyte also passes through voids in the dielectric layer (for example, pores in the porous body, meshes, or fiber gaps). Examples of the material constituting the dielectric layer include non-conductive inorganic materials such as glass fiber and quartz fiber; non-conductive organic materials such as sponge and cotton. Non-conductive inorganic materials, particularly glass fibers and quartz fibers are preferably used because they are electrochemically stable. The dielectric layer is preferably elastic. When sandwiched between the cathode layer and the solid electrolyte membrane, the solid electrolyte membrane is pressed against the anode layer by the elastic force of the dielectric layer, and the adhesion between the anode layer and the solid electrolyte membrane can be enhanced.

  The raw material water supplied from the raw material water supply unit is allowed to flow to the anode part (A), and the electrolytic solution supplied from the electrolyte solution supply part is allowed to flow to the cathode part. When a voltage is applied between the cathode portion and the anode portion by the voltage application means, water molecules are electrolyzed. The electrolysis of water molecules changes the product depending on the applied voltage. If electric power (voltage, current) used in normal electrolysis is used, oxygen gas is generated at the anode and hydrogen gas is generated at the cathode. If power (high voltage, current) higher than that used in normal electrolysis is used, water containing abundant oxygen radicals (radical oxygen water) is generated at the anode part. The ozone generation reaction includes a reaction in which ozone is generated directly from water molecules (6-electron reaction) and a reaction in which oxygen is first generated from water molecules and the oxygen is changed to ozone (4 + 2 electron reaction). In the present invention, it is preferable to perform electrolysis by 4 + 2 electron reaction because current efficiency can be improved. Examples of the oxygen radical include active oxygen, hydrogen peroxide, ozone, and hydroxyl radical. Further, hydrogen gas or hydrogen radicals are generated at the cathode portion. The generated radical oxygen water (Wo) is discharged from the anode part. Hydrogen gas is discharged to the outside in a state of being dissolved in the electrolytic solution or in the form of bubbles.

  The waste electrolyte solution (D) can be recycled by adjusting the chlorine ion concentration, hydrogen ion concentration, cation concentration, etc., and returning it to the electrolyte supply unit. The ion concentration can be adjusted using, for example, an anion exchange resin or a cation exchange resin. Thereby, the exchange frequency of electrolyte solution can be reduced. The waste electrolyte (D) may be mixed with radical oxygen water generated at the anode part. When mixed in this way, piping for disposal of the waste electrolyte (D) can be omitted.

  The amount of the electrolytic solution supplied from the electrolytic solution supply unit to the cathode part of the electrolytic cell is not particularly limited. / 100,000 or more is preferable. The upper limit is not particularly limited, but is, for example, 1/1 from the viewpoint of cost.

The electrolyte supplied from the electrolyte supply unit has a pressure of preferably 1 atm (about 0.1 MPa) or more, more preferably 0.2 MPa or more, and even more preferably 0.3 MPa in the cathode portion of the electrolysis cell ( 1 ). As described above, it is particularly preferably set to 0.4 MPa or more. The upper limit of the pressure can be set according to the structure and material of the apparatus, the apparatus manufacturing cost, etc., and is preferably 50 MPa, more preferably 30 MPa, and still more preferably 10 MPa. Examples of means for increasing the pressure of the electrolyte include a throttle valve, an orifice, a pump, and preferably a plunger pump.

  The temperature of the electrolytic solution supplied from the electrolytic solution supply unit is preferably 0 to 45 ° C, more preferably 10 to 35 ° C in the cathode portion of the electrolytic cell (1). If the temperature is too high, decomposition of oxygen radicals is promoted and the concentration of radical oxygen water tends to be low.

  The amount of the raw water supplied from the raw water supply unit to the anode part of the electrolysis cell is not particularly limited, but is preferably an amount such that the average residence time of the raw material water in the anode part is greater than 0 seconds and 10 seconds or less, More preferably, the amount is greater than 0 seconds and less than 7 seconds. By shortening the average residence time of the raw material water in the anode part, fresh raw water can be supplied by quickly flowing out ions and bubbles generated on the anode part side. As a result, the generation efficiency of radical oxygen water in the electrolytic cell can be increased.

The raw water supplied from the raw water supply section has a pressure of preferably 1 atm (about 0.1 MPa) or more, more preferably 0.2 MPa or more, and further preferably 0.3 MPa in the anode part of the electrolysis cell ( 1 ). As described above, it is particularly preferably set to 0.4 MPa or more. The upper limit of the pressure can be set according to the structure and material of the apparatus, the apparatus manufacturing cost, etc., and is preferably 50 MPa, more preferably 30 MPa, and still more preferably 10 MPa. Examples of means for increasing the pressure of the raw water include a throttle valve, an orifice, a pump, and preferably a plunger pump.

  The temperature of the raw water supplied from the raw water supply section is preferably 0 to 45 ° C., more preferably 10 to 35 ° C. in the anode part of the electrolytic cell (1). If the temperature is too high, decomposition of oxygen radicals is promoted and the concentration of radical oxygen water tends to be low.

A DC voltage may be applied continuously or intermittently between the anode part and the cathode part. When the DC voltage is intermittently applied, deterioration of the anode part and the cathode part may be suppressed. The intermittent application of the DC voltage is not particularly limited by the on-off interval. A known power supply device can be used as the voltage applying means. An AC power supply capable of supplying predetermined power, for example, a 100V or 200V AC power supply, is prepared, and the converter converts the AC to DC. The direct current electricity used in the present invention preferably has a voltage of 4 to 20 V, and preferably has a current per unit area of the cell of 0.1 to 5 A / cm ² . This voltage and current facilitate the generation of ozone and active oxygen by reaction at the anode.

The radical oxygen water obtained by the apparatus of the present invention preferably has a radical amount of about 10 ¹⁷ / L or more. The high-concentration radical oxygen water obtained by the apparatus of the present invention is used after being diluted to a predetermined concentration with warm water. The temperature of hot water used for dilution is preferably 40 to 90 ° C, more preferably 40 to 60 ° C. The temperature of the hot water can be adjusted by hot water preparation means such as a water heater. Moreover, dilution with warm water can be performed by the mixing means of the temperature adjusting unit. In order to prevent the backflow, the mixing means preferably has a pipe disposed so that the radical oxygen water is sucked into the warm water, and more preferably has a check valve. When diluted with warm water of 40 ° C. or higher, it is possible to easily supply high-concentration, high-temperature radical oxygen water, which is difficult to supply with conventional devices. Radical oxygen water having a temperature of about 39 to 45 ° C. is suitable for human bathing, bathing and partial bathing (half-body bathing, foot bath, etc.) and the like. In addition, radical oxygen water at a dead temperature (a temperature similar to body temperature) has little effect on pulse, blood pressure, and respiration, and is suitable for bathing people with heart disease. Furthermore, since peripheral blood vessels are not contracted, it is also suitable for cleaning peripheral parts such as limbs of people who tend to have peripheral circulation failure. The hot water used for the dilution can use water obtained by bypassing part of the raw water supplied from the raw water supply part without passing through the anode part. The bypass water can be gas-fired and heated by a heating means such as an electric heater or a heat exchanger to be adjusted to a predetermined temperature.

In the apparatus shown in FIG. 1, raw material water at a temperature of 20 ° C. is passed through the anode part, and an electrolytic solution at a temperature of 20 ° C. (NaCl aqueous solution with a concentration of 0.001 mol / l) is passed through the cathode part, and a current density of 0.5 A / m. Electrolysis was performed at ² .
A part of the raw water (fresh water) is bypassed without passing through the anode part, and the temperature after mixing is approximately 23 ° C, 30 ° C, 35 ° C, 45 ° C and 50 ° C with a heater with temperature control. Warmed to. Each heated fresh water and ozone water obtained by the electrolysis were mixed. The relationship (■) between the temperature of the obtained diluted ozone water and the ozone concentration is shown in FIG. As plotted by ■ in FIG. 3, high ozone concentration is maintained even in high temperature water of about 50 ° C.

For comparison, raw water at a predetermined temperature (20 ° C., 25 ° C., 30 ° C., 35 ° C., 40 ° C. and 45 ° C.) is passed through the anode part, and a predetermined temperature (20 ° C., 25 ° C., 30 ° C., Electrolysis was performed at a current density of 0.5 A / m ² by flowing an electrolytic solution (NaCl aqueous solution having a concentration of 0.001 mol / l) at 35 ° C., 40 ° C. and 45 ° C. FIG. 3 shows the relationship between the temperature of the obtained ozone water and the ozone concentration (♦). As plotted with ◆ in FIG. 3, the ozone concentration rapidly decreases at high temperatures.

  The present invention is not limited to the above-described embodiment, and it is obvious that modifications and changes can be made without departing from the scope and spirit of the invention.
