Description

[0001] APPARATUS FOR MANUFACTURING HYDROGEN WATER [0002]

The present invention relates to a device for producing hydrogen water and, more particularly, to a device for producing hydrogen water capable of producing hydrogen water at a high concentration, which can neutralize active oxygen in the body to improve various kinds of diseases, .

Active oxygen has been reported to cause various diseases and aging. It is also known that administration of hydrogen to the body is effective in neutralizing active oxygen in the body to treat various diseases, promote health, or improve the constitution. Accordingly, in order to administer hydrogen into the body, hydrogen water produced by dissolving hydrogen in water has received attention, and many manufacturing apparatuses for producing such hydrogen water have been developed.

Generally, hydrogenated water is produced by an electrolysis method using electrolysis of water and an electroless method using a metal having a tendency to ionize more than hydrogen, and in most cases, it is manufactured by electrolysis.

First, in the electrolytic method, when an anode and a cathode are provided in an electrolytic cell and current is applied, hydrogen is generated in the cathode and oxygen is generated in the anode. At this time, hydrogen generated in the cathode is mixed with water to produce hydrogen water, and the oxygen generated in the anode is released into the atmosphere. In the case of the electroless plating method, as use of a large metal ionization tendency than hydrogen, such as magnesium or calcium, when these metals come into contact with water, this ionization tendency than hydrogen is greater metal is oxidized to a cation, water is OH ^- and H ⁺ . At this time, a part of dissociated H ⁺ remains in water in an ionic state or a hydrogen atom state, and is produced as a hydrogenated water.

Regarding the above-mentioned production of hydrogenated water, for example, Korean Patent No. 10-1442565 and Korean Patent No. 10-1443817 disclose an electrolytic water-producing apparatus, and Korean Patent No. 10 -1318577 discloses an apparatus for producing hydrogen-free water using an electroless method.

On the other hand, in general, most of the drinking water has odor such as water smell or chlorine disinfection. In this case, it is known that in the case of watery fish, it is caused by components such as iron contained in raw water such as tap water. The hydrogenated water contains heavy metals and the like. Particularly, the electrolytic or electroless electrolytic water produced contains a salt component. For example, in the electrolytic method, salt components such as hypochlorite and metal salts are contained.

However, the conventional apparatus for producing hydrogen-containing water has not been able to find technical means for effectively removing water, fish odor, heavy metals, and salts. In some cases, a filter such as a carbon filter is provided in order to remove odors of water or chlorine disinfection. However, in the case of a carbon filter, odor removal efficiency is lowered, and components such as hypochlorite and metal salts are difficult to remove.

According to one embodiment, the filter unit 100 may have a laminated structure of a screen filter, an activated carbon filter, and a hollow fiber filter.

The hydrogen generating unit 200 generates water by introducing water (raw water). According to a preferred embodiment, the hydrogen generating unit 200 is installed at the rear end of the filter unit 100, and the filtered water is introduced through the filter unit 100 to generate hydrogenated water.

In the present invention, the hydrogen-generating unit 200 is not particularly limited as long as it can generate hydrogen-containing water from the introduced water. The hydrogen generating unit 200 includes components using electrolysis (electrolysis), electroless, magnetic force, low-temperature pyrolysis, photocatalyst, and / or fermentation method as a typical method used for generating hydrogen water can do.

At this time, the metal may be selected from, for example, magnesium and / or calcium. In the present invention, the hydrogen-generating unit 200 such as an electrolytic system and an electroless electrolytic system has the same structure as that of the ordinary one, so that a more detailed description thereof will be omitted.

The hydro-scrubbing unit 300 purifies the hydrogen-containing water by flowing the hydrogen-containing water generated in the hydrogen-generating unit 200. As mentioned above, most of the hydrogen water produced through the hydrogen-generating unit 200 includes components such as heavy metals, hypochlorite and / or metal salts. The water purification unit 300 purifies and removes the above components. FIG. 2 shows a water purification unit 300 according to an embodiment of the present invention.

2, the water purifying unit 300 includes a housing 320 and a ceramic ball layer 340 disposed in the housing 320. The housing 320 has an inlet 321 through which the hydrogen generated in the hydrogen generating unit 200 flows and an outlet 322 through which the hydrogen purified by contacting at least the ceramic ball layer 340 is discharged. The ceramic ball layer 340 is formed by laminating porous ceramic balls 342.

According to one embodiment, the housing 320 includes a cylindrical body 324, an upper cap 325 hermetically coupled to the upper portion of the body 324, and an upper cap 325 hermetically coupled to the upper portion of the body 324 And a lower cap 326. At this time, the ceramic ball layer 340 is installed in the main body 324, the inlet port 321 is formed in the upper cap 325, and the outlet port 322 is formed in the lower cap 326. The housing 320 may be made of, for example, a plastic material.

According to a more specific embodiment, the water-purifying unit 300 includes a housing 320, a first support member 351 disposed on the upper portion of the housing 320, A cylindrical inner filtration screen 331 provided in the housing 320 and a cylindrical outer filtration filter 331 installed in the housing 320 and provided on the outer side of the inner filtration screen 331, A ceramic ball layer 340 filled between the inner filtration screen 331 and the outer filtration screen 332 and a purifying filter 360 installed below the second support member 352 .

The first support member 351 and the second support member 352 are made of, for example, a plastic material or a metal material. The first support member 351 supports the upper ends of the inner filtration screen 331 and the outer filtration screen 332 and the second support member 352 supports the inner filtration screen 331 and the outer filtration screen 332, As shown in Fig. The first support member 351 and the second support member 352 may have, for example, a disk-like shape.

The first support member 351 is disposed in close contact with the upper end of the main body 324 within the upper cap 325 of the housing 320. The first support member 351 is for supporting the upper ends of the inner filtration screen 331 and the outer filtration screen 332 and is formed with a first support portion 351b protruding downward. The first support member 351 is formed with an inlet 351a for introducing the hydrogen water introduced into the inlet 321 into the first space S1 in the body 324. The inlet 351a may be plural.

The second support member 352 is disposed in the lower cap 326 of the housing 320 and is closely attached to the lower end of the main body 324. The second support member 352 is for supporting the upper ends of the inner filtration screen 331 and the outer filtration screen 332 and is formed with a second support portion 352b protruding upward. The second support member 352 is formed with a discharge port 352a for discharging the hydrogen water flowing into the second space S2 in the main body 324 to the outlet port 322. [

The inner filtration screen 331 and the outer filtration screen 332 are for filtering foreign substances or the like remaining in the hydrophobic water, and can be selected from, for example, a metal mesh. The inner filtration screen 331 and the outer filtration screen 332 support the side surface of the ceramic ball layer 340 to prevent the ceramic ball 342 from being separated. The inner filtration screen 331 and the outer filtration screen 332 are cylindrically shaped and are provided in the body 324 of the housing 320 and are disposed between the first support member 351 and the second support member 352 And is fixed by the first supporting portion 351b and the second supporting portion 352b. At this time, the inner filtration screen 331 is installed at the center of the main body 324, and the outer filtration screen 332 is installed outside the inner filtration screen 331.

The ceramic ball layer 340 is filled between the inner filtration screen 331 and the outer filtration screen 332. The ceramic ball layer 340 is formed by stacking a plurality of ceramic balls 342, and the ceramic balls 342 are porous. The specific configuration of the ceramic ball 342 will be described later.

The purge filter 360 is installed in the lower cap 326 of the housing 320 and is installed below the second support member 352. The purge filter 360 purifies the discharged hydrogen water through the discharge port 352a of the second support member 352. The purifying filter 360 may be selected from a filter capable of removing components such as, for example, odor remaining in the water (in the water), gas, chlorine, and / or heavy metals. The purifying filter 360 may be selected from carbon filters and / or activated carbon filters, for example.

The water generated in the water generating unit 200 passes through the inlet 321 of the housing 320 and the inlet 351a of the first supporting member 351 and then flows into the first space The outer filtration screen 332, the ceramic ball layer 340, and the inner filtration screen 331 in sequence along the slit S1. At this time, foreign matter is primarily filtered while passing through the outer filtration screen 332. At the same time, components such as heavy metals, hypochlorite and / or metal salts are purified and removed while passing through the ceramic ball layer 340. Thereafter, the foreign matters are filtered while passing through the inner filtration screen 331.

Hydrophonic water having passed through the inner filtration screen 331 passes through the purifying filter 360 along the second space S2 in the body 324 and the discharge port 352a of the second support member 352 , And is discharged through an outlet 322 of the housing 320. At this time, components such as odor (water intoxication), gas, chlorine, and / or heavy metals remaining in the hydrogen water are removed while passing through the purifying filter 360. Accordingly, the hydrogen water discharged through the outlet 322 has a high concentration.

Meanwhile, in the present invention, the ceramic ball 342 is a sintered body of natural mineral, which has a spherical shape. In the present invention, a spherical shape does not mean a complete spherical shape. The ceramic balls 342 may have an average diameter of, for example, 2 mm to 12 mm, and more specifically, may have an average diameter of 5 mm to 8 mm. The ceramic ball 342 may be made of any suitable material, including, for example, zeolite, tourmaline, magnetite, feldspar, aluminum oxide, magnesium oxide, white clay, at least one natural mineral selected from the group consisting of apatite and bentonite. Ceramic balls 342, preferably zeolite, and the like.

Also, in the present invention, the ceramic ball 342 is porous having a plurality of pores. At this time, the ceramic ball 342 preferably has a porosity of, for example, 35% to 60%. And the ceramic balls 342 may have a density of 1.2 g / g to 1.8 g / g. When having pores and densities in this range, excellent purification ability and good strength can be obtained. In the present invention, the porosity refers to the volume percentage (%) occupied by the pores in the entire volume of the ceramic balls 342. The porosity depends specifically on the following equation.

[Mathematical Expression]

Porosity (%) = (Vp / V) x 100

(Where V is the total volume of the ceramic balls 342 and Vp is the total volume of the pores formed in the ceramic balls 342)

In the present invention, the porosity of the ceramic ball 342 may act as an important factor in the cleaning ability. When the porosity is less than 35%, the purifying ability (adsorptivity) of heavy metals, hypochlorite and / or metal salts may be somewhat small. When the porosity exceeds 60%, the mechanical strength is low and durability may be deteriorated. For this reason, the density of the ceramic balls 342 is preferably 1.2 g / g to 1.8 g / g. The porosity and / or density of the ceramic balls 342 can be controlled, for example, by controlling the particle size of natural minerals and / or the content of porogen.

In one example, the ceramic ball 342 is obtained by mixing a natural mineral particle obtained by crushing natural minerals as described above and a pore-forming agent for pore formation, and then forming the mixture into a spherical shaped body Followed by firing at a high temperature. In addition, the mixture includes natural mineral particles and a pore-forming agent, and may further include an inorganic binder. At this time, it is possible to produce pores and densities having the above ranges by controlling the size of the natural mineral particles, the content of the pore-forming agent, and / or the content of the inorganic binder.

The natural mineral particles may be selected from those having an average particle size of, for example, 0.5 to 50 in consideration of pores and density. Preferably an average particle size of 5 to 30, more preferably an average particle size of 10 to 15.

The pore-forming agent is selected from organic materials. At the time of high - temperature firing, a large number of pores are formed by removing the pore - forming agent (organic material), and the ceramic balls 342 have porosity. The pore-forming agent may be any one capable of forming a large number of pores by burning away by high-temperature firing. The pore-forming agent can be selected, for example, from a resin, and the kind thereof is not particularly limited. The pore-forming agent specifically includes at least one selected from a thermoplastic resin and a thermosetting resin. The pore-forming agent is more specifically exemplified by polyvinyl alcohol (PVA), polyvinyl butyral (PVB), polyvinyl pyrrolidone (PVP), acrylic resin, urethane resin, epoxy resin, phenol resin and unsaturated polyester resin And the like. Such pore-forming agents can also function as a shape-retaining function. That is, the pore forming agent can maintain the spherical shape of the ceramic balls 342 before firing.

The pore-forming agent is not particularly limited, but may be used in an amount of 0.8 to 15 parts by weight based on 100 parts by weight of natural mineral particles. If the content of the pore-forming agent is less than 0.8 part by weight, the porosity may be too low. On the contrary, if the content is more than 15 parts by weight, porosity may be too high.

The inorganic binder is not particularly limited as long as it can bind natural mineral particles by firing. The inorganic binder can be selected, for example, from those which can have melt adhesion upon firing. At this time, in the present invention, the inorganic binder does not mean only inorganic substances but includes inorganic-organic complexes. According to an exemplary embodiment of the present invention, the inorganic binder preferably includes a silicate. The silicate is useful in the present invention, especially when the natural mineral particles are silicate natural minerals containing at least silicon (Si) such as zeolite. That is, the silicate is advantageous for improving the bonding strength of silicate natural mineral particles such as zeolite. At this time, the silicate is preferably selected from ethyl silicate. The silicate preferably contains at least tetraethyl orthosilicate (TEOS) among the ethyl silicate. This tetraethylorthosilicate (TEOS) is coated on the surface of the silicate mineral particles during sintering to greatly increase the sinterability of the particles, so that after the sintering, excellent bonding force between the mineral particles is achieved.

The inorganic binder is not particularly limited, but may be used in an amount of 0.5 to 12 parts by weight based on 100 parts by weight of the natural mineral particles. When the content of the inorganic binder is less than 0.5 parts by weight, the binding force between the natural mineral particles may be weakened. When the content of the inorganic binder is more than 12 parts by weight, The amount of particles and organic matter used is low, and it may be difficult to show good porosity.

The ceramic ball 342 can be manufactured by molding a mixture containing the natural mineral particles, the pore-forming agent, and the inorganic binder as described above into a spherical shape, followed by high-temperature firing. At this time, pore-forming agent (organic material) is exhausted and pores are formed by high-temperature firing, so that natural mineral particles are sintered and bonded with excellent bonding force through the inorganic binder. In this sintering process, the sintering temperature is preferably 1,000 or more, for example, 1,000 to 1,500, for good sinterability. If the sintering temperature is less than 1,000, the sintering property may be rather small. When the sintering temperature exceeds 1,500, for example, fine cracks may occur in the sintered body. The firing time is not particularly limited, but may be, for example, 2 hours or more, and for example, 2 hours to 24 hours. The firing time may be more specifically, for example, 5 hours to 15 hours, but it may vary depending on the firing temperature and the like.

The ceramic balls 342 as described above have good mechanical strength together with excellent cleaning ability. Specifically, the ceramic balls 342 effectively purify (adsorb) and remove heavy metals, hypochlorite and / or metal salts contained in the hydrogenated water, and have high durability because of high mechanical strength.

3 shows a water purification unit 300 according to another embodiment of the present invention. Referring to FIG. 3, according to another embodiment of the present invention, the water purification unit 300 may further include a vertical pipe 370 installed inside the cylindrical inner filtration screen 331. At this time, the hydrogen water having passed through the inner filtration screen 331 flows along the vertical pipe 370. More specifically, the vertical tube 370 has a tubular shape such as a cylindrical shape or a polygonal shape (rectangular shape or the like) and is vertically installed at the center of the housing body 324, that is, at an inner center of the inner filtration screen 331 And is vertically installed.

The vertical tube 370 has an inlet 370a through which the hydrogen is drawn and an outlet 370b through which the hydrogen is drained. The inlet 370a is connected to the outlet of the main body 324 of the housing 320, And the outlet portion 370b is positioned below the main body 324 of the housing 320. [ At this time, as shown in FIG. 3, the inflow portion 370a may have a structure expanded upward. In addition, the outlet 370b is provided to communicate with the outlet 352a of the second support member 352. The outflow portion 370b may be coupled to the second support portion 352b of the second support member 352 through a thread S, for example.

The water flowed through the inner filtration screen 331 flows into the inflow portion 370a of the vertical tube 370 along the second space S2 in the body 324 when the vertical tube 370 is installed, And then flows along the outflow portion 370b of the vertical tube 370 through the purifying filter 360 and then through the outlet 322 of the housing 320. [ According to the present invention, the installation of the vertical tube 370 increases the residence time of, for example, water in the main body 324, thereby improving the cleaning ability. Specifically, the hydrogen water that has passed through the inner filtration screen 331 is not immediately discharged but is raised by the vertical tube 370 to increase the residence time in the body 324. As a result, the contact time with the ceramic ball layer 340 becomes long and the improved purification can proceed.

Also, in the present invention, the vertical tube 370 may be selected from a metal tube, a plastic tube, a ceramic tube, and the like. In addition, the vertical tube 370 may be selected from a ceramic tube having porosity at least on the surface (inner surface and / or outer surface). When the vertical tube 370 is made of a porous ceramic tube, its cleaning ability can be further improved by having a function of adsorbing and removing a salt component and the like. At this time, the vertical tube 370 has a hollow tube shape, and may be constructed in the same manner as the ceramic ball 342.

Specifically, the vertical tube 370 may have a porosity of 35% to 60% and may be composed of a mixture of natural mineral particles, a pore-forming agent, and a mixture containing an inorganic binder. The natural mineral particles, pore-forming agent, inorganic binder and the like constituting the vertical tube 370 are the same as those of the ceramic ball 342, so a detailed description thereof will be omitted.

According to the present invention described above, an improved apparatus for producing hydrogen water is provided. Specifically, components such as salts contained in the hydrogenated water are effectively removed by the porous ceramic balls 342, so that the hydrogenated water having a high concentration can be easily produced.

In addition, the hydrogen water purifying unit 300 illustrated in FIG. 2 can be structurally simple and efficiently purified. And, as shown in Fig. 3, in the case of further including the vertical tube 370, the cleaning ability can be further improved by the increase of the residence time.
