Detailed Description
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Fig. 1 shows a schematic configuration of an embodiment of a hydrogenation apparatus according to the present invention. The hydrogenation apparatus 1 is an apparatus for hydrogenating water, and hydrogenated water is used for preparation of dialysate, for example, as water for preparation of dialysate (hereinafter, hydrogenated water is sometimes referred to as water for preparation of dialysate). In recent years, hemodialysis using hydrogen-added water for preparation of dialysate has been attracting attention because it is effective for suppressing oxidative stress of patients.
The hydrogenation apparatus 1 is disposed, for example, downstream of the reverse osmosis membrane treatment apparatus 200. The hydrogenation apparatus 1 and the reverse osmosis membrane treatment apparatus 200 may be integrated to constitute one apparatus. A dialysis liquid raw material diluting device (not shown) for diluting a liquid dialysis raw material with water for preparing a dialysis liquid, for example, is connected to the downstream side of the hydrogenation device 1.
The reverse osmosis membrane treatment apparatus 200 purifies water supplied from the outside using a reverse osmosis membrane. The reverse osmosis membrane treatment apparatus 200 and the hydrogenation apparatus 1 are connected through a treated water supply passage 10. The water purified by the reverse osmosis membrane treatment apparatus 200 (hereinafter referred to as treated water) is supplied to the hydrogenation apparatus 1 through the treated water supply path 10 and used as raw water (hereinafter referred to as raw water) for generating hydrogen-added water for preparing dialysate.
The hydrogenation apparatus 1 for producing water for preparing dialysate adds hydrogen to raw water supplied from the reverse osmosis membrane treatment apparatus 200 to produce hydrogen-added water for preparing dialysate. The hydrogenation apparatus 1 is connected to the dialysis raw material diluting apparatus through a hydrogenation water supply passage 20. The hydrogenated water produced by the hydrogenation apparatus 1 is supplied to the aforementioned raw dialysate diluting apparatus through the hydrogenated water supply passage 20, and is used for preparation of dialysate.
Fig. 2 shows the main constitution of the hydrogenation apparatus 1. The hydrogenation apparatus 1 includes a hydrogen-dissolved water generation unit 2 and a hydrogen-permeable membrane module 3.
The hydrogen-dissolved water generator 2 generates hydrogen-dissolved water and supplies the hydrogen-dissolved water to the hydrogen permeable membrane module 3. The hydrogen-dissolved water is water into which hydrogen molecules are dissolved. In the present embodiment, an electrolytic cell 4 is used as the hydrogen-dissolved water generating unit 2. The electrolytic cell 4 generates hydrogen molecules by electrolyzing water and generates hydrogen-dissolved water.
The electrolytic cell 4 is formed by separating a first pole chamber 40a provided with a first power supply element 41 and a second pole chamber 40b provided with a second power supply element 42 by a diaphragm 43.
The polarity of the first power supplier 41 is different from that of the second power supplier 42. That is, one of the first power supplier 41 and the second power supplier 42 functions as an anode power supplier, and the other functions as a cathode power supplier. In the present embodiment, the first power feeder 41 functions as an anode power feeder, and the second power feeder 42 functions as a cathode power feeder. Water is supplied to both of the first pole chamber 40a and the second pole chamber 40b of the electrolytic chamber 40, and a dc voltage is applied to the first power feeder 41 and the second power feeder 42, whereby electrolysis of water occurs in the electrolytic chamber 40.
The polarities of the first power feeder 41 and the second power feeder 42 and the voltages applied to the first power feeder 41 and the second power feeder 42 are controlled by a control unit (not shown). The control unit includes, for example, a CPU (central Processing unit) that executes various arithmetic Processing and information Processing, a memory that stores a program that is responsible for the operation of the CPU, and various information, and the like. The control unit controls each unit of the apparatus in addition to the first power feeder 41 and the second power feeder 42.
Hydrogen gas and oxygen gas are generated by electrolyzing water in the electrolysis chamber 40. For example, hydrogen gas is generated in the second electrode chamber 40b on the cathode side, and a hydrogen-dissolved water in which the hydrogen molecules are dissolved is generated and supplied to the hydrogen permeable membrane module 3. The hydrogen-dissolved water generated by such electrolysis is also referred to as "electrolyzed hydrogen water". On the other hand, in the first electrode chamber 40a on the anode side, oxygen gas is generated.
As the separator 43, for example, a solid polymer film made of a fluorine-based resin having a sulfonic acid group is used as appropriate. The solid polymer membrane moves oxonium ions generated in the first electrode chamber 40a on the anode side by electrolysis to the second electrode chamber 40b on the cathode side, and serves as a raw material for generating hydrogen molecules. Therefore, hydroxide ions are not generated during electrolysis, and the pH of the electrolyzed hydrogen water does not change.
The hydrogen permeable membrane module 3 includes a first chamber 31, a second chamber 32, and a hydrogen permeable membrane 33. The first chamber 31 and the second chamber 32 are separated by a hydrogen permeable membrane 33.
The first chamber 31 is connected to the second pole chamber 40b of the electrolytic bath 4 through a hydrogen water supply passage 50. The hydrogen-dissolved water generated in the second pole chamber 40b of the electrolytic cell 4 is supplied to the first chamber 31 through the hydrogen water supply passage 50.
On the other hand, the second chamber 32 is connected to the treated water supply passage 10. The raw water is supplied from the reverse osmosis membrane treatment device 200 to the second chamber 32.
The hydrogen permeable membrane 33 is composed of, for example, a hollow fiber membrane as a porous membrane through which hydrogen molecules pass. The hydrogen-dissolved water generated by the electrolytic cell 4 is successively supplied to the first chamber 31, and therefore the hydrogen-dissolved concentration of the water in the first chamber 31 is greater than the hydrogen-dissolved concentration of the water in the second chamber 32. The hollow fiber membrane moves hydrogen dissolved in a liquid from a first chamber 31 having a high dissolved hydrogen concentration to a second chamber 32 having a low dissolved hydrogen concentration. The hydrogen permeable membrane 33 is not limited to a hollow fiber membrane as long as it has a function of allowing hydrogen molecules dissolved in a liquid to permeate from a high-concentration liquid side to a low-concentration liquid side.
In the present invention, in order to generate hydrogen-containing water in the second chamber 32, hydrogen molecules dissolved in the hydrogen-containing water in the first chamber 31 are moved from the first chamber 31 to the second chamber 32 through the hydrogen permeable membrane 33. With this configuration, the contamination of bacteria into the first chamber 31 to which the hydrogen-dissolved water is supplied is suppressed. Therefore, the hydrogen-added water with high cleanliness can be easily produced with a simple structure. Further, since the hydrogen-dissolved water is supplied to the first chamber 31 to generate the hydrogen-added water in the second chamber, a configuration for supplying the hydrogen gas after pressurization is not necessary, and the hydrogen-added water can be generated with a simple and inexpensive configuration.
The first direction D1 in which the hydrogen-dissolved water flows in the first chamber 31 is preferably different from the second direction D2 in which the raw water (or the hydrogenated water) flows in the second chamber 32, with the hydrogen permeable membrane 33 interposed therebetween. By making the first direction D1 different from the second direction D2, the hydrogen molecules are promoted to permeate the hydrogen permeable membrane 33, that is, the hydrogen molecules are promoted to move from the first chamber 31 to the second chamber 32, and the concentration of hydrogen dissolved in the hydrogen-containing water is easily increased.
From the above viewpoint, a more preferable relationship of the first direction D1 and the second direction D2 is reverse to each other. Further, the first direction D1 and the second direction D2 opposite to each other can be easily achieved by disposing the inlet of the first chamber 31 and the outlet of the second chamber 32 and the inlet of the second chamber 32 and the outlet of the first chamber 31 adjacent to each other.
In the hydrogen permeable membrane module 3 of the present embodiment, the first direction D1 and the second direction D2 are arranged in the vertical direction, but may be arranged in the horizontal direction or inclined in the oblique direction.
As shown in fig. 1, in the present embodiment, treated water subjected to reverse osmosis membrane treatment by a reverse osmosis membrane treatment apparatus 200 is used as water to be electrolyzed in an electrolytic bath 4. The treated water is supplied to the electrolytic bath 4 through a treated water supply path 10, a treated water supply path 11 branched from the treated water supply path 10, and the like. That is, the electrolytic cell 4 of the hydrogen-dissolved water generator 2 and the second chamber 32 of the hydrogen permeable membrane module 3 receive treated water from the reverse osmosis membrane treatment apparatus 200 as the same source. With such a configuration, the hydrogenation apparatus 1 and the piping around it are simplified.
The hydrogenation apparatus 1 of the present embodiment further includes a water circulation path 5, and the water circulation path 5 circulates the hydrogen-dissolved water between the second electrode chamber 40b and the first chamber 31 of the electrolytic cell 4. The hydrogen water supply passage 50 connecting the second pole chamber 40b and the first chamber 31 of the electrolytic cell 4 constitutes a part of the circulation water passage 5.
The hydrogen-dissolved water is circulated in the circulation water path 5 while the electrolysis is continued in the electrolytic cell 4, whereby the concentration of the hydrogen-dissolved water in the first chamber 31 is increased. Thus, the difference in the dissolved hydrogen concentration between the first chamber 31 and the second chamber 32 is maintained, and therefore the dissolved hydrogen concentration of the hydrogen-added water can be easily increased.
The circulation water path 5 of the present embodiment is provided with a pump 6 for circulating the hydrogen-dissolved water in the circulation water path 5 and a tank 7 for storing the hydrogen-dissolved water. The pump 6 is disposed between the tank 7 and the electrolytic bath 4. The pump 6 is controlled by the control unit, and drives and circulates the hydrogen-dissolved water in the circulation water path 5. This allows the hydrogen-dissolved water produced by the electrolytic cell 4 to be quickly supplied to the first chamber 31, thereby increasing the water pressure in the first chamber 31. On the other hand, by storing the hydrogen-dissolved water in the tank 7, the capacity of the circulation water path 5 is increased, and the fluctuation of the hydrogen-dissolved concentration in the circulation water path 5 is suppressed.
Before the raw water is supplied to the second chamber 32, the electrolytic cell 4 is operated by increasing the voltage applied to the first power feeder 41 and the second power feeder 42 in advance, and the concentration of the dissolved hydrogen in the circulating water passage 5 can be easily increased to the saturation concentration. This increases the difference in the hydrogen-dissolved concentration between the first chamber 31 and the second chamber 32, and the hydrogen-dissolved concentration of the hydrogen-added water can be easily increased.
The upper part of the tank 7 is opened. Therefore, the hydrogen molecules that have not been dissolved in the electrolytic cell 4 move in the circulation water path 5 as bubbles, flow into the tank 7, and a part of the hydrogen molecules escapes from the upper part of the tank 7.
In the present embodiment, the throttle valve 8 is disposed in the region of the circulation water path 5 where the hydrogen-dissolved water returns from the first chamber 31 to the tank 7. The throttle valve 8 is driven by, for example, an electromagnetic force controlled by the control unit, and regulates the hydrogen-dissolved water flowing through the circulation water passage 5. The throttle valve 8 restricts the hydrogen-dissolved water flowing in the circulation water path 5 in a state where the pump 6 is operated, so that the water pressure in the first chamber 31 is increased. That is, the pump 6 and the throttle valve 8 function as a water pressure raising means for raising the water pressure in the first chamber 31. The water pressure in the first chamber 31 is increased by the pump 6 and the throttle valve 8, thereby promoting the movement of hydrogen molecules from the first chamber 31 to the second chamber 32, and the dissolved hydrogen concentration of the hydrogen-added water can be easily increased.
The treated water supply path 10 is provided with a water inlet valve 12 and a flow meter 13. The inlet valve 12 is driven by electromagnetic force controlled by the control unit, for example, and regulates the flow of the treated water in the treated water supply path 10. The flow meter 13 detects a flow rate per unit time (hereinafter simply referred to as a flow rate) of the treated water flowing through the treated water supply path 10, and outputs the flow rate to the control unit. The control unit controls the inlet valve 12 according to the flow rate input from the flowmeter 13. Thereby, the flow rate of the treated water supplied as the raw water to the second chamber 32 is optimized.
A water supply valve 14 is provided in the treated water supply passage 11. The water supply valve 14 is driven by electromagnetic force controlled by the control unit, for example, and regulates the flow of the treated water in the treated water supply path 11. More specifically, when the tank 7 is filled or replenished with water for electrolysis, the water supply valve 14 is opened, and when raw water is supplied to the second chamber 32 of the hydrogen permeable membrane module 3, the water supply valve 14 is closed.
A purge valve 16 is provided in the exhaust passage 15 (see fig. 2) extending upward from the first pole chamber 40a of the electrolytic chamber 40. Oxygen generated in the first pole chamber 40a by electrolysis is discharged from the exhaust passage 15 and the purge valve 16.
The tank 7 is provided with a heater 17. The heater 17 heats the water in the tank 7. Hot water or steam generated by heating water in the tank 7 is supplied to the pump 6, the electrolytic cell 4, the first chamber 31 of the hydrogen permeable membrane module 3, and the like via the circulation water path 5, and is cleaned. At the time of the above cleaning, the cleaning valve 19 provided in the cleaning path 18 branched from the exhaust passage 15 is opened, thereby promoting circulation of hot water or the like in the first pole chamber 40 a.
The cleaning of the electrolytic bath 4, the first chamber 31, and the like is preferably performed periodically (for example, once every 1 day). A drain valve 22 provided in a drain passage 21 branched from the circulation water path 5 is opened to discharge hot water for washing and the like. The drain passage 21 of the present embodiment branches off from the circulation water passage 5 connecting the tank 7 and the pump 6. The drain channel 21 may be directly connected to the tank 7.
After the completion of the washing, if the washing valve 19 and the drain valve 22 are closed and the inlet valve 12 is opened, the tank 7 is filled with water for electrolysis.
Fig. 3 shows a process of a hydrogenation method using the hydrogen permeation membrane module 3. The hydrogenation method comprises the following steps: a first step S1 of generating a hydrogen-dissolved water in which hydrogen molecules are dissolved; a second step S2 of supplying a hydrogen-dissolved water to the first chamber 31 of the hydrogen permeable membrane module 3; and a third step S3 of supplying raw water to the second chamber 32 of the hydrogen permeable membrane module 3. In the first step S1, water is electrolyzed in the electrolytic cell 4 to generate a hydrogen-dissolved water. In the second step S2, the hydrogen-dissolved water produced in the first step S1 flows into the first chamber 31. In the third step S3, raw water is supplied from the reverse osmosis membrane treatment device 200 to the second chamber 32.
At this time, since the hydrogen-dissolved concentration of the hydrogen-dissolved water in the first chamber 31 is higher than the hydrogen-dissolved concentration of the raw water in the second chamber 32, hydrogen molecules dissolved in the hydrogen-dissolved water in the first chamber 31 permeate the hydrogen permeable membrane 33 and move to the second chamber 32. Thereafter, the hydrogen molecules moved to the second chamber 32 are dissolved in the raw water in the second chamber 32. Therefore, a process for pressurizing hydrogen molecules is not required, and hydrogen-added water can be produced with a simple and inexpensive configuration.
The hydrogenation apparatus and the like of the present invention have been described above in detail, but the present invention is not limited to the above specific embodiments and can be carried out in various modifications. That is, the hydrogenation apparatus 1 for generating a hydrogen-added water may include the first chamber 31 to which a hydrogen-dissolved water is supplied, the second chamber 32 to which raw water is supplied, and the hydrogen permeable membrane 33 for moving hydrogen molecules dissolved in the hydrogen-dissolved water from the first chamber 31 to the second chamber 32 in order to generate the hydrogen-added water in the second chamber 32.
In the hydrogenation apparatus 1 shown in fig. 1, the hydrogen-dissolved water generator 2 that generates hydrogen-dissolved water to be supplied to the first chamber 31 is not limited to the electrolytic cell 4 that electrolyzes water. For example, the hydrogen generator may be a device that generates hydrogen-dissolved water by dissolving hydrogen molecules generated by a chemical reaction between water and magnesium or the like in water, or a device that generates hydrogen-dissolved water by dissolving hydrogen (hydrogen molecules) supplied from a hydrogen tank in water.
The hydrogenation apparatus 1 can be applied to various uses in addition to the generation of the hydrogenation water for the preparation of the dialysate. For example, the method can be widely applied to the production of hydrogenated water for drinking, cooking, or agriculture.
