Regarding the technical means of our inventors, several preferred embodiments are described in detail below in conjunction with the drawings, so as to provide a thorough understanding and approval of the present invention.

Hereinafter, an embodiment of the present invention will be described based on the drawings.

Fig. 1 shows a schematic configuration of an embodiment of the hydrogenation apparatus of the present invention. The hydrogenation unit 1 is a device for hydrogenation in water. The hydrogenated water is used for the preparation of dialysate, for example, as dialysate preparation water (hereinafter, the hydrogenated water is sometimes referred to as dialysate preparation water). ). In recent years, hemodialysis using hydrogenated water in the preparation of dialysate is effective in suppressing the oxidative stress of patients, so it has attracted attention.

The hydrogenation unit 1 is arranged, for example, on the downstream side of the reverse osmosis membrane treatment unit 200. The hydrogenation unit 1 and the reverse osmosis membrane treatment unit 200 can be integrated to form one unit. On the downstream side of the hydrogenation device 1, for example, a dialysis agent diluting device (not shown) that dilutes a liquid dialysis agent using dialysate preparation water is connected.

The reverse osmosis membrane processing device 200 uses a reverse osmosis membrane to purify water supplied from the outside. The reverse osmosis membrane treatment device 200 and the hydrogenation device 1 are connected through a treated water supply channel 10. The water purified by the reverse osmosis membrane treatment device 200 (hereinafter referred to as treated water) passes through the treated water supply channel 10 and is supplied to the hydrogenation device 1 as raw water for producing hydrogenated water for preparing dialysate ( Hereinafter, it is referred to as raw water) for use.

The hydrogenation device 1 for producing dialysate preparation water hydrogenates the raw water supplied from the reverse osmosis membrane processing device 200 to produce hydrogenated water for dialysate preparation. The hydrogenation device 1 and the above-mentioned dialysis agent dilution device are connected through a hydrogenation water supply channel 20. The hydrogenated water generated by the hydrogenation device 1 is supplied to the above-mentioned dialysis agent diluting device through the hydrogenation water supply channel 20 for the preparation of dialysate.

FIG. 2 shows the main structure of the hydrogenation unit 1. The hydrogenation device 1 includes a hydrogen generation unit 2 and a hydrogen permeable membrane module 3.

The hydrogen generating unit 2 generates hydrogen and supplies the hydrogen to the hydrogen permeable membrane module 3. In this embodiment, the electrolytic cell 4 is applied as the hydrogen generating unit 2. The electrolytic cell 4 electrolyzes water to generate hydrogen.

The electrolytic cell 4 is formed by a diaphragm 43 separating the first electrode chamber 40 a equipped with the first power supply body 41 and the second electrode chamber 40 b equipped with the second power supply body 42.

The polarity of the first power supply body 41 is different from the polarity of the second power supply body 42. That is, one of the first power supply body 41 and the second power supply body 42 is used as an anode power supply body, and the other is used as a cathode power supply body. In this embodiment, the first power supply body 41 is used as an anode power supply body, and the second power supply body 42 is used as a cathode power supply body. By supplying water to both the first electrode chamber 40a and the second electrode chamber 40b of the electrolysis chamber 40, and applying a DC voltage to the first power supply body 41 and the second power supply body 42, electrolysis of water occurs in the electrolysis chamber 40 .

FIG. 3 is a block diagram showing the electrical configuration of the hydrogenation device 1. The polarities of the first power supply 41 and the second power supply 42 and the voltage applied to the first power supply 41 and the second power supply 42 are controlled by the control unit 9. The control unit 9 has, for example, a CPU (Central Processing Unit) that executes various arithmetic processing, information processing, and the like, and a memory that stores programs and various information in charge of the operation of the CPU. In addition to controlling the first power supply body 41 and the second power supply body 42, the control unit 9 is also responsible for the control of each part of the device.

A current detector 44 is provided on the current supply line between the first power supply body 41 and the control unit 9. The current detector 44 is also provided on the current supply line between the second power supply body 42 and the control unit 9. The current detector 44 detects the electrolysis current supplied to the first power supply body 41 and the second power supply body 42 and outputs an electric signal corresponding to the value to the control unit 9.

The control unit 9 controls the DC voltage applied to the first power supply body 41 and the second power supply body 42 based on the electrical signal output from the current detector 44, for example. More specifically, the control unit 9 performs feedback control on the DC voltage applied to the first power supply 41 and the second power supply 42 so that the electrolysis current detected by the current detector 44 becomes a predetermined desired value. For example, when the electrolysis current is too large, the control unit 9 reduces the voltage, and when the electrolysis current is too small, the control unit 9 increases the voltage. Thus, the electrolysis current supplied to the first power supply body 41 and the second power supply body 42 is appropriately controlled.

In FIGS. 1 and 2, hydrogen and oxygen 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 the hydrogen gas is supplied to the hydrogen permeable membrane module 3. 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 uses electrolysis to move the oxonium ions generated in the first electrode chamber 40a on the anode side to the second electrode chamber 40b on the cathode side as a raw material for generating hydrogen. Therefore, hydroxide ions are not generated during electrolysis, and the pH of the electrolyzed water in the first electrode chamber 40a and the second electrode chamber 40b 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 and the second electrode chamber 40b of the electrolytic cell 4 are connected through the hydrogen supply channel 5. The hydrogen gas generated by the second electrode chamber 40 b of the electrolytic cell 4 is supplied to the first chamber 31 through the hydrogen supply channel 5.

On the other hand, the second chamber 32 is connected to the treated water supply channel 10. The raw water is supplied to the second chamber 32 from the reverse osmosis membrane treatment device 200.

The hydrogen permeable membrane 33 is composed of, for example, a hollow fiber membrane that is a porous membrane through which hydrogen gas permeates. The hydrogen gas generated by the electrolytic cell 4 is successively supplied to the first chamber 31, so the pressure in the first chamber 31 is increased. The hollow fiber membrane moves hydrogen gas from the first chamber 31 with a high pressure to the second chamber 32 with a low pressure. The hydrogen permeable membrane 33 is not limited to a hollow fiber membrane as long as it has a function of permeating hydrogen gas from the high-pressure fluid side to the low-pressure fluid side.

In this embodiment, in order to generate hydrogenated water in the second chamber 32, the hydrogen permeable membrane 33 moves the hydrogen gas successively supplied from the electrolytic cell 4 from the first chamber 31 to the second chamber 32. Thereby, a structure such as a pump for pressurizing hydrogen gas is unnecessary, and hydrogenated water can be produced with a simple and inexpensive structure.

However, the hydrogen permeable membrane 33 is consumed with use. Furthermore, the dissolved hydrogen concentration of the hydrogenated water taken out from the second chamber 32 depends on the degree of consumption of the hydrogen permeable membrane 33. More specifically, when the hydrogen permeable membrane 33 is new, the hydrogenated water generated in the second chamber 32 has a high dissolved hydrogen concentration. As the hydrogen permeable membrane 33 is consumed, the above-mentioned dissolved hydrogen concentration decreases. For this reason, in the present hydrogenation device 1, the control unit 9 functions as a determination unit that determines the degree of consumption of the hydrogen permeable membrane 33 and monitors the degree of consumption of the hydrogen permeable membrane 33. In addition, the determination of the degree of consumption of the hydrogen permeable membrane 33 by the control unit 9 is performed at any time or periodically.

A pressure sensor (pressure detection unit) 51 is provided in the hydrogen supply passage 5. The pressure sensor 51 detects the pressure in the hydrogen supply passage 5. The hydrogen supply passage 5 communicates with the first chamber 31, and therefore the pressure in the hydrogen supply passage 5 is substantially equal to the pressure in the first chamber 31. Therefore, the pressure in the first chamber 31 is detected by the pressure sensor 51. The pressure sensor 51 may be provided in the first chamber 31. The pressure sensor 51 outputs an electric signal corresponding to the detected pressure of the first chamber 31 to the control unit 9.

For example, if the hydrogen permeable membrane is consumed, the pressure of the first chamber may exceed a predetermined range. Therefore, when the pressure of the first chamber 31 exceeds a preset threshold value, it can be determined that the consumption of the hydrogen permeable membrane 33 is progressing. Multiple thresholds can be set. For this reason, the control unit 9 determines the degree of consumption of the hydrogen permeable membrane 33 based on the electrical signal input from the pressure sensor 51, that is, the pressure of the first chamber 31. As a result, it is possible to accurately determine the degree of consumption of the hydrogen permeable membrane module 3 with a simple and inexpensive configuration.

The present hydrogenation device 1 is provided with an output unit 91 that outputs the consumption degree of the hydrogen permeable membrane 33 determined by the control unit 9. The output unit 91 outputs the above-mentioned consumption level by sound, image, or the like. Such an output unit 91 can be realized by a speaker device, an LED (light emitting diode), a liquid crystal display (Liquid Crystal Display), or the like. In addition, the output unit 91 may be configured to output a wireless or wired signal corresponding to the degree of consumption of the hydrogen permeable membrane 33 to a computer device that manages the hydrogenation device 1. With such an output unit 91, the manager of the hydrogenation device 1 can easily know the degree of consumption of the hydrogen permeable membrane 33.

As shown in FIG. 1, in this embodiment, as the water to be electrolyzed in the electrolytic cell 4, treated water after the reverse osmosis membrane treatment by the reverse osmosis membrane treatment device 200 is applied. The treated water is supplied to the electrolytic cell 4 through the treated water supply channel 10 and the treated water supply channel 11 branched from the treated water supply channel 10. That is, the electrolytic cell 4 of the hydrogen generating unit 2 and the second chamber 32 of the hydrogen permeable membrane module 3 receive the supply of treated water from the reverse osmosis membrane treatment apparatus 200 which is the same water source. With this configuration, the piping of the hydrogenation unit 1 and its surroundings is simplified.

Preferably, a hydrogen concentration sensor (hydrogen concentration detection unit) 21 is provided in the hydrogenated water supply channel 20. The hydrogen concentration sensor 21 detects the dissolved hydrogen concentration of the hydrogenated water taken out from the second chamber 32 and outputs a corresponding electrical signal to the control unit 9.

For example, the consumption of the hydrogen permeable membrane 33 sometimes affects the dissolved hydrogen concentration of the hydrogenated water. Therefore, in the case where the dissolved hydrogen concentration of the hydrogenated water is less than the preset threshold value, it can be determined that the consumption of the hydrogen permeable membrane 33 is progressing. For this reason, the control unit 9 may be configured to determine the degree of consumption of the hydrogen permeable membrane 33 based on the electrical signal input from the hydrogen concentration sensor 21, that is, the dissolved hydrogen concentration of the hydrogenated water.

For example, the control unit 9 may be configured to determine the consumption of the hydrogen permeable membrane 33 only based on the dissolved hydrogen concentration of the hydrogenated water, or may be configured to determine the consumption based on the pressure of the first chamber 31 and the dissolved hydrogen concentration of the hydrogenated water. degree. Furthermore, in the latter case, it may also be configured to take the logical AND function of the consumption determined based on the pressure of the first chamber 31 and the consumption determined based on the dissolved hydrogen concentration of the hydrogenated water. Or logical OR (OR) function to comprehensively determine the above consumption. Furthermore, it may be configured to correct the consumption degree based on the dissolved hydrogen concentration of the hydrogenated water after determining the consumption degree of the hydrogen permeable membrane 33 based on the pressure of the first chamber 31. After determining the degree of consumption of the hydrogen permeable membrane 33 based on the dissolved hydrogen concentration, the degree of consumption is corrected based on the pressure of the first chamber 31. As a result, it is possible to accurately determine the degree of consumption of the hydrogen permeable membrane module 3 with a simple and inexpensive configuration.

In the present embodiment, the control unit 9 controls the DC voltage applied to the first power supply body 41 and the second power supply body 42 based on the electrical signal input from the hydrogen concentration sensor 21, that is, the dissolved hydrogen concentration of the hydrogenated water. For example, when the dissolved hydrogen concentration detected by the hydrogen concentration sensor 21 is less than the target value, the pressure of the first chamber 31 is increased by increasing the DC voltage applied to the first power supply body 41 and the second power supply body 42, thereby increasing The dissolved hydrogen concentration of hydrogenated water. On the other hand, when the dissolved hydrogen concentration detected by the hydrogen concentration sensor 21 exceeds the target value, the pressure in the first chamber 31 is suppressed by reducing the DC voltage applied to the first power supply 41 and the second power supply 42. Thereby reducing the dissolved hydrogen concentration of hydrogenated water. In this way, the control unit 9 controls the DC voltage applied to the first power supply 41 and the second power supply 42 to make the dissolved hydrogen concentration constant, thereby generating hydrogenated water with a desired dissolved hydrogen concentration in the hydrogenation device 1 and supplying it to Diluting device for original dialysis agent.

As described above, if the consumption of the hydrogen permeable membrane 33 progresses, the dissolved hydrogen concentration of the hydrogenated water tends to decrease. Therefore, in order to compensate for this decrease, the control unit 9 increases the direct current applied to the first power supply 41 and the second power supply 42 The voltage thereby increases the pressure of the first chamber 31.

For this reason, the control unit 9 of the present hydrogenation device 1 determines the degree of consumption of the hydrogen permeable membrane 33 based on the electrical signal input from the pressure sensor 51, that is, the pressure of the first chamber 31. As a result, it is possible to accurately determine the degree of consumption of the hydrogen permeable membrane module 3 with a simple and inexpensive configuration.

In addition, as the consumption of the hydrogen permeable membrane 33 progresses, there is a tendency that even if the pressure of the first chamber 31 is increased, the dissolved hydrogen concentration of the hydrogenated water is difficult to sufficiently increase. Thus, the control unit 9 may be configured to determine the degree of consumption of the hydrogen permeable membrane 33 based on the relationship between the pressure of the first chamber 31 and the dissolved hydrogen concentration of the hydrogenated water. For example, it may be configured to predetermine the correlation equation between the pressure of the first chamber 31 and the dissolved hydrogen concentration of the hydrogenated water and the degree of consumption of the hydrogen permeable membrane 33 through experiments, etc., and the pressure and the dissolved hydrogen The concentration is substituted into the above-mentioned relational expression to obtain the degree of consumption of the hydrogen permeable membrane 33.

A water inlet valve 12 and a flow meter (flow rate detection unit) 13 are provided in the treated water supply passage 10. The water inlet valve 12 is driven by, for example, electromagnetic force controlled by the control unit 9 to restrict the treated water flowing in the treated water supply channel 10. The flow meter 13 detects the flow rate per unit time of the treated water flowing in the treated water supply channel 10, that is, the raw water supplied to the second chamber 32 (hereinafter, simply referred to as the flow rate or the supply amount), and outputs it to the control unit 9 . The control unit 9 controls the water inlet valve 12 based on the flow rate input from the flow meter 13. Thereby, the flow rate of the treated water supplied to the second chamber 32 as raw water is optimized.

A water supply valve 14 is provided in the treated water supply passage 11. The water supply valve 14 is driven by, for example, electromagnetic force controlled by the control unit 9 to restrict the treated water flowing in the treated water supply passage 11. More specifically, when filling or replenishing the electrolytic cell 4 with water for electrolysis, the water supply valve 14 is opened, and thereafter, when raw water is supplied to the second chamber 32 of the hydrogen permeable membrane module 3, the water supply valve 14 is closed.

The dissolved hydrogen concentration of the hydrogenated water taken out from the second chamber 32 also depends on the supply amount of raw water to the second chamber 32. For example, if the supply amount of raw water to the second chamber 32 increases, the dissolved hydrogen concentration of the hydrogenated water tends to decrease.

Therefore, the control unit 9 is preferably configured to determine the hydrogen permeable membrane 33 based on the supply amount of raw water detected by the flow meter 13 in addition to the pressure of the first chamber 31 detected by the pressure sensor 51 and the like. Of consumption. Thereby, the control unit 9 can determine the degree of consumption of the hydrogen permeable membrane 33 more accurately.

An exhaust valve 16 is provided in an exhaust passage 15 (refer to FIG. 2) extending upward from the first electrode chamber 40 a of the electrolysis chamber 40. The oxygen gas generated in the first electrode chamber 40 a by the electrolysis is discharged from the exhaust passage 15 and the exhaust valve 16.

FIG. 4 shows the processing procedure of the method of determining the degree of consumption of the hydrogen permeable membrane 33 in the hydrogen permeable membrane module 3. The method for determining the degree of consumption of the hydrogen permeable membrane 33 includes: step S1, detecting the pressure of the first chamber 31; step S2, detecting the concentration of dissolved hydrogen; step S3, detecting the supply amount of raw water; step S4, determining the degree of consumption of the hydrogen permeable membrane 33 ; And step S5, output the judgment result.

In step S1, the pressure of the first chamber 31 is detected by the pressure sensor 51. In step S2, the dissolved hydrogen concentration of the hydrogenated water taken out from the second chamber 32 is detected by the hydrogen concentration sensor 21. In step S3, the supply amount of raw water to the second chamber 32 is detected by the flow meter 13. The order of step S1 to step S3 does not matter. That is, for example, step S3 may be executed first, and steps S1 and S2 may be executed thereafter.

In step S4, based on the pressure of the first chamber 31 detected in step S1, the dissolved hydrogen concentration of hydrogenated water detected in step S2, and the supply amount of raw water detected in step S3, the control unit 9 determines hydrogen Permeate the degree of consumption of the membrane 33. Then, in step S4, the determination result of step S3 is output by the output unit 91.

According to the method for determining the degree of consumption, the degree of consumption of the hydrogen permeable membrane 33 can be accurately determined with a simple and inexpensive configuration.

The hydrogenation device 1 and the like of the present invention have been described in detail above, but the present invention is not limited to the specific embodiments described above and can be modified into various forms and implemented. That is, the hydrogenation device 1 includes at least a first chamber 31 to which hydrogen-dissolved water is supplied, a second chamber 32 to which raw water is supplied, and hydrogen gas is transferred from the first chamber 31 to the second chamber in order to generate hydrogenated water in the second chamber 32. The hydrogen permeable membrane 33 moving 32, the pressure sensor 51 that detects the pressure of the first chamber 31, and the control unit 9 that determines the degree of consumption of the hydrogen permeable membrane 33 based at least on the pressure of the first chamber 31 are sufficient.

In addition, in the hydrogenation device 1 shown in FIG. 1, the hydrogen generating unit 2 that generates hydrogen to be supplied to the first chamber 31 is not limited to the electrolytic cell 4 that electrolyzes water. For example, it may be a device that generates hydrogen gas through a chemical reaction of water and magnesium, or a storage tank filled with hydrogen gas.

In addition, as a pressure detection unit that detects the pressure of the first chamber 31, instead of a pressure sensor, the control unit 9 may be configured to estimate the pressure of the first chamber 31 based on, for example, an integrated value of the electrolysis current.

In addition to generating hydrogenated water for dialysate preparation, the hydrogenation device 1 can be applied to various applications. For example, it can also be widely applied to the production of hydrogenated water for drinking, cooking, or agriculture.

In addition, the consumption determination method, that is, the consumption determination method of the hydrogen permeable membrane 33 may include at least step S1 of detecting the pressure of the first chamber 31 and step S4 of determining the degree of consumption of the hydrogen permeable membrane 33. For example, step S2 of detecting the concentration of dissolved hydrogen or step S3 of detecting the supply amount of raw water may be omitted. In this case, in step S4, the control unit 9 determines the degree of consumption of the hydrogen permeable membrane 33 based on the dissolved hydrogen concentration of the dialysate preparation water detected in step S1.
