Description

The present invention relates to a method and an apparatus for producing hydrogenated water .

  There are various redox systems in mammals including humans (hereinafter referred to as “living bodies”), and many of them are conjugated to each other and involved in in vivo redox reactions. The redox potential of the in vivo redox system is directly related to the free energy change of the reaction and the equilibrium constant, and is useful for predicting the direction of these reactions.

  The redox reaction of mammalian organs or in vivo reactions has a low potential, usually in the range of -100 mV to -400 mV, and the pH is in the range of 3-7. It is said that when the oxidation-reduction potential of the body fluid increases, active oxygen tends to stay and damage the organ. In particular, the intestines where the intestinal microorganisms actively act to digest and absorb nutrients must be maintained in an anaerobic reducing atmosphere.

For example, the redox potential of “acetic acid + CO ₂ + 2H ⁺ / α-ketoglutaric acid reaction” is −673 mV, the redox potential of “acetic acid + CO ₂ / pyruvate reaction” is −699 mV, and “acetic acid + 2H ⁺ / acetaldehyde” in vivo. The redox potential of the “reaction” is −581 mV, the redox potential of ferredoxin is −413 mV, the redox potential of “xanthine + H ⁺ / hypoxanthine + H ₂ O” is −371 mV, and the redox potential of “uric acid + H ⁺ / xanthine + H ₂ O”. Is -360 mV, the redox potential of “acetoacetic acid + 2H ⁺ / β-hydroxybutyric acid reaction” is −346 mV, and the redox potential of “cystine + 2H ⁺ / 2 cysteine reaction” is −340 mV.

  Thus, the reactions of enzymes, coenzymes, and metabolism-related substances in the living body are in an environment where the redox potential is low. In addition, water or food having a low redox potential has an action of separating and eliminating active oxygen that oxidizes the body and molecules or atoms having one or more unpaired electrons, that is, free radicals, It is said to promote the reaction of an active oxygen scavenging enzyme called SOD (superoxide dismutase).

  Body fluids provide a place for metabolic reactions in the body, including redox reactions. Body fluids occupy almost 60% of the living body. Body fluids are composed mainly of water, and electrolytes, proteins, and the like as important components. This is the reason why water having a low redox potential is effective in vivo.

  By the way, the redox potential of tap water is +400 to +800 mV, and the pH is in the range of 6.5 to 8. Therefore, it is considered that tap water cannot be balanced with a living organ having a redox potential in the range of −100 mV to −400 mV.

  At present, several methods have been proposed for reducing the redox potential of water in a mixed state of an oxidant and a reductant, such as tap water, such as an electrolysis method and a high-frequency current application method. However, in any case, the balance between the value of the redox potential and the pH is not an ideal method from the viewpoint of the in vivo redox reaction.

Many biological reactions involve oxidation-reduction reactions and play an extremely important role in metabolic reactions and the like. In addition, in a system (solution) containing an oxidant and a reductant, not limited to a living body, an inactive electrode that itself does not participate in the oxidation-reduction reaction, such as platinum, is immersed in the solution. Appears. This potential difference is an oxidation-reduction potential (Oxidation-Reduction Potential = ORP), and the unit is expressed in mV. Now, when the activity of an oxidant of a certain substance is represented as [Ox] and the activity of a reductant is represented as [Red], the mixed state of both is represented by the formula (1).
[Ox] + ne → [Red] (1)
In the formula (1), e is an electron, and n is the number of moving electrons.

The oxidation-reduction potential (EmV) of the electrode reaction equation represented by the equation (1) is represented by the Nernst equation (2).
E = E ₀ + (RT / nF) ln [Ox] / [Red] (2)
In formula (2), R is a gas constant (8.31 Jmol ⁻¹ K ⁻¹ ), T is an absolute temperature (K), and F is a Faraday constant (96406 JV ⁻¹ ). E ₀ is a standard redox potential when [Ox] = [Red].

  In equation (2), ln [Ox] / [Red] is a natural logarithm. Therefore, the negative (−) value of the oxidation-reduction potential E can be increased as the denominator, that is, [Red] is made extremely larger than the numerator, that is, [Ox]. That is, theoretically, the greater the activity of the reductant [Red] than the activity of the oxidant [Ox], the more the redox potential can be made negative.

  That is, in the method of reducing the oxidation-reduction potential of the raw material water to a negative potential by blowing hydrogen into the raw material water in a mixed state of the oxidant and the reductant, the activity of the reductant [Red] is changed to the oxidant [Ox]. It is important to make it larger than the activity of. In this case, it is preferable to blow hydrogen while bringing the raw material water in a mixed state of an oxidant and a reductant into contact with a reduction catalyst in which a metal is supported on silica-based quartz porphyry, because efficiency is improved.

  The present inventors have developed several hydrogen water production apparatuses and the like so far based on the above-described theoretical background (Patent Document 1).

  Patent Document 1 includes a “reaction tank, a raw material water supply system pipe that is watertightly coupled to the reaction tank, a decompression system pipe that is watertightly coupled to the reaction tank, a hydrogen supply system pipe that is watertightly coupled to the reaction tank, A hydrogen water production apparatus comprising a product water extraction system pipe that is watertightly coupled to a reaction vessel, wherein (a) the reaction vessel is connected to at least two upper chambers and lower chambers through a partition plate having through holes.

By the way, in recent years, research on fine bubbles and development of their uses have been actively conducted. Microbubbles are defined as fine bubbles having a diameter of 10 to several tens of micrometers. Usually, the diameter of bubbles generated or formed in water is about several millimeters, but applications utilizing the feature that microbubbles are 1/100 or less have been developed. In other words, microbubbles make use of properties such as high absorption efficiency in liquids, excellent uniformity and dispersibility, enhancing biological activity of living organisms, and generating heat up to about 70 ° C when exposed to ultrasonic waves. It is applied to cancer diagnosis and treatment. Specifically, under the guidance of Prof. Hirofumi Taisei, Department of Civil Engineering, National Tokuyama National College of Technology, the growth of cultured oysters, the shipment of summer oysters, the purification of water quality, etc. were reported by oxygen supply and sterilization by microbubbles. Yes.

Accordingly, the present invention relates to a method and an apparatus for producing hydrogenated water, which solves the above-described conventional problems. By adding a large amount of fine bubbles to the hydrogen water disclosed in Patent Document 1, such hydrogenated water is contained. An object of the present invention is to provide a method and apparatus for producing hydrogenated water containing a large amount of fine bubbles in order to expand the industrial use of water .

The hydrogenated water of the present invention contains a large amount of hydrogen, maintains an oxidation-reduction potential of −400 mV or less, a pH slightly higher than 7, and hydrogen gas in a wide range of diameters from millibubbles, microbubbles, and micronanobubbles. It is contained in large quantities as bubbles.

Here, regarding the fine bubbles, those in which the diameter of the bubble in the nascent stage is in millimeters are millibubbles, those in the range of 10 to several tens of micrometers are microbubbles, and those in the range of several hundreds of nanometers to 10 micrometers are micronanobubbles In some cases, those of several hundred nanometers or less are classified as nanobubbles. In the present invention, this classification is partially adopted. That is, the hydrogenated water of the present invention is characterized in that it contains bubbles of hydrogen gas having a wide range of diameters from millibubbles having a diameter of 0.12 mm or less to microbubbles and micronanobubbles in the generation period .

In developing the means for solving the problems, the inventors of the present invention (1) surely blow a predetermined amount of hydrogen gas into the raw water, and (2) the hydrogen gas contained in the raw water with a predetermined diameter. (3) Production of hydrogenated water in a continuous system, not a batch system, (4) A large installation space is not required, and it is mobile as a shower if necessary. We examined that it can be handled easily.

As a result, the basic structure of a manufacturing apparatus of pressurized hydrogen water of the present invention, both ends an opening shape which is formed in the tubular body, it is formed at one end of the tubular body, a raw material supplying raw water at a high pressure and water supply systems, are watertight coupled to the tube body, the raw material water supplied from the raw water supply system, and a hydrogen supply system for supplying hydrogen substantially right angle, downstream of the hydrogen supply system in the tube body to be formed on the tube in the longitudinal direction, and the raw water supply system raw water supplied to the tube from a diffusion chamber for diffusing the mixed fluid of hydrogen supplied to the tube body from the hydrogen supply system, the A porous element filled in the diffusion chamber, having a predetermined pore diameter, for allowing the supplied mixed fluid of raw water and hydrogen to pass therethrough, and formed at the other end of the tubular body, the porous element comprising an outlet for discharging the mixed fluid of raw water and hydrogen that has passed through the result, the front A plurality of pipes are connected to the raw water supply system and the discharge port adjacent to each other, and are arranged in a plurality of substantially straight lines along the longitudinal direction, and the raw water and hydrogen discharged from the discharge port of one pipe body The mixed fluid is supplied at a high pressure from the raw water supply system of the adjacent pipe body into the pipe body, mixed with hydrogen in the diffusion chamber of the adjacent pipe body, and then passed through the porous element to be diffused. The hydrogenated water containing a large amount of hydrogen gas fine bubbles was continuously produced .

  The main member of the apparatus for producing hydrogenated water of the present invention is a tubular body whose cross section is mainly circular or rectangular. The tube material is preferably a metal such as carbon steel or stainless steel, but may also be glass, plastic, ceramics, rubber, or a combination thereof, which has strength to withstand negative pressure.

  An opening serving as a water injection port is formed at one end of the tube, and a raw water supply system for supplying raw water at a high pressure is watertightly coupled. The raw material water supply system is connected to a water supply facility having a water pressure of 0.1 to 0.5 MPa, usually tap water, and a pump is connected between them. The supply amount of raw water is preferably 8 to 20 liters / minute.

  The inside of the pipe body of the water injection port formed at one end of the pipe body is a nozzle, and the water jetted at a high pressure is jetted at a higher pressure. Normally, since the raw water is injected in an incompressible state, that is, below the speed of sound, the shape of the nozzle may be a so-called tapered nozzle whose flow area is smoothly reduced appropriately. However, when the raw material water is injected in a compressible state, that is, at a sound velocity or higher, a tapered nozzle may be used until the flow velocity becomes equal to the sound velocity. However, in order to receive a jet flow exceeding the sound velocity, the flow area is increased again. Therefore, a divergent nozzle is required, and a tapered nozzle and a divergent nozzle are combined.

The pipe is provided with a hydrogen supply system for supplying hydrogen at a substantially right angle to the raw water supplied from the raw water supply system in a watertight manner. The hydrogen supply system is preferably provided with a check valve to prevent water supplied from the raw water supply system from flowing back to the hydrogen supply system.
The hydrogen supply system incorporates a hydrogen cylinder, a gas pressure adjusting device, piping, and the like, and injects hydrogen gas with adjusted pressure.

  The supply pressure of hydrogen gas is preferably 0.2 to 0.8 MPa, and the supply amount is preferably 0.1 to 1 liter / min.

In the tube, a diffusion chamber is formed downstream of the hydrogen supply system in the longitudinal direction of the tube in a so-called double tube structure. Diffusion chamber is for diffusing the raw water from the raw water supply system is supplied to the tube, a mixed fluid of hydrogen supplied to the tube body from the hydrogen supply system.

  The diffusion chamber has a reduced-diameter structure, that is, a throttle structure from both ends toward the center, and a negative pressure is formed at the throttle portion. Since the diffusion chamber has a throttle structure and a negative pressure is formed, the raw water supplied from the raw water supply system to the pipe, the hydrogen supplied from the hydrogen supply system to the pipe, The suction effect of the mixed fluid is enhanced.

  The diffusion chamber is filled with a porous element having a predetermined pore size. The porous element disposed in the diffusion chamber is a kind of filter. A mixed fluid composed of raw water and hydrogen introduced into the diffusion chamber is jetted through a porous element to form bubbles having the same diameter as the pores formed in a porous shape.

  The material of the porous chamber element is not particularly limited as long as it has pores having a diameter in the range of 120 μm to 2 μm. Gunmetal, bronze, nickel, stainless steel, sintered bodies such as ceramics, and wire mesh can be used. In the case where the wear resistance and the produced hydrogenated water are used for drinking, a sintered body of stainless steel is preferable.

  The shape of the perforated chamber element has various shapes such as a disk, a cylinder, a cylinder bottom, and a base, but a cylinder is preferable for insertion into a tube.

  The thickness of the porous chamber element is 5 to 20 mm, preferably 5 to 10 mm, and is appropriately selected depending on conditions such as water pressure and water amount.

  Sintered Tyler meshes available from the market range from 20 to 250 meshes (0.833 mm to 0.061 mm), but to form fine bubbles with a diameter of 10 μm or less, select 120 mesh or more. To do. The larger the Tyler mesh (the smaller the mm), the higher the concentration of dissolved hydrogen can be obtained. However, the pressure loss of the hydraulic water amount increases and the production efficiency decreases. Therefore, it is important to select appropriately depending on the amount of dissolved hydrogen and water to be obtained.

The apparatus for producing hydrogenated water of the present invention is used by connecting two or more units. In particular, in the case of tap water, in order to secure a dissolved hydrogen amount of 1.3 ppm or more at a water amount of 15 liters / minute or more, it is necessary to use two or more connected together.
