Description

Electrolysis tank and electrolyzed water generator

The present invention relates to an electrolytic cell that electrolyzes water to generate electrolytic hydrogen water, and an electrolyzed water generating apparatus including the same.

Conventionally, an electrolyzed water generating apparatus that includes an electrolyzer having an anode chamber and a cathode chamber partitioned by a diaphragm, and electrolyzes raw water such as tap water introduced into the electrolyzer to generate electrolyzed hydrogen water. It is known (see, for example, Patent Document 1).

Electrolytic hydrogen water generated in the cathode chamber of the electrolyzed water generator is expected to exhibit an excellent effect in improving gastrointestinal symptoms. In recent years, electrolytic hydrogen water in which hydrogen gas generated in the cathode chamber by the electrolysis is dissolved has been attracting attention as being suitable for removal of active oxygen.

Japanese Patent No. 569724

In the electrolyzed water generating apparatus described in Patent Document 1, the first convex portion disposed on the inner surface of the first case piece of the electrolytic cell is in contact with the anode feeder, and is disposed on the inner surface of the second case piece. The second convex portion thus brought into contact with the cathode power supply body. The first convex portion and the second convex portion sandwich the laminate composed of the anode power feeder, the diaphragm, and the cathode power feeder.

By the way, in order to increase the dissolved hydrogen concentration of electrolyzed hydrogen water, it is necessary to increase the amount of hydrogen gas generated in the electrolyzer and to efficiently dissolve the generated hydrogen gas in the electrolyzed water. Since the amount of hydrogen gas generated depends on the electrolysis current supplied to each power feeder, it is necessary to increase the electrolysis current in order to generate a large amount of hydrogen gas in the electrolytic cell.

In order to increase the electrolysis current, it is important to increase the electrolysis voltage applied to each power supply or to suppress the electrical resistance between the diaphragm and each power supply. The latter technique is particularly useful because it can increase the generation amount of hydrogen gas while suppressing the power consumption of the electrolyzed water generator, and thus the generation efficiency of hydrogen gas is improved.

In the electrolytic cell having the structure shown in Patent Document 1, in order to increase the generation efficiency of hydrogen gas while using an electrolytic cell having a limited capacity, the contact pressure between the diaphragm and each power feeder is increased between the two. It is effective to reduce the contact resistance.

However, when water flow to the electrolytic cell is started, the first case piece and the second case piece are expanded outward, that is, in a direction away from the diaphragm due to the water pressure in the electrolytic chamber. Such expansion of the first case piece and the second case piece causes a decrease in the contact pressure between the first convex portion and the anode feeder and the contact pressure between the second convex portion and the cathode feeder, It acts so that the contact pressure with each power feeding body decreases. Therefore, as the contact resistance between the diaphragm and each power feeding body increases, the electrolysis current decreases, so that the generation efficiency of hydrogen gas may not be sufficiently increased.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a schematic configuration of an electrolyzed water generating apparatus 1 of the present embodiment. The electrolyzed water generating apparatus 1 can be used for generating water for domestic beverages and cooking and for generating dialysate for hemodialysis.

The electrolyzed water generating apparatus 1 includes an electrolysis tank 4 in which an electrolysis chamber 40 to which water to be electrolyzed is supplied, and an anode power supply 41 and a cathode power supply 42 that are disposed to face each other in the electrolysis chamber 40. And a diaphragm 43 disposed between the anode power supply 41 and the cathode power supply 42. Another electrolytic cell may be provided upstream or downstream of the electrolytic cell 4. Further, another electrolytic cell may be provided in parallel with the electrolytic cell 4. A configuration equivalent to that of the electrolytic cell 4 can also be applied to the electrolytic cell provided separately.

The diaphragm 43 divides the electrolysis chamber 40 into an anode chamber 40A on the anode feeder 41 side and a cathode chamber 40B on the cathode feeder 42 side. Water is supplied to both the anode chamber 40 A and the cathode chamber 40 B of the electrolysis chamber 40, and a DC voltage is applied to the anode power supply 41 and the cathode power supply 42, whereby water is electrolyzed in the electrolysis chamber 40.

The diaphragm 43 allows ions generated by electrolysis to pass therethrough, and the anode feeder 41 and the cathode feeder 42 are electrically connected through the diaphragm 43. For the diaphragm 43, for example, a solid polymer material made of a fluorine-based resin material having a sulfonic acid group is used.

In the electrolytic cell 4 having the diaphragm 43 using a solid polymer material, neutral electrolytic hydrogen water and electrolytic oxygen water are generated. By electrolyzing water in the electrolytic chamber 40, electrolytic hydrogen water in which hydrogen gas is dissolved is obtained in the cathode chamber 40B, and electrolytic oxygen water in which oxygen gas is dissolved is obtained in the anode chamber 40A.

The electrolyzed water generating apparatus 1 further includes a control means 6 for controlling the electrolyzer 4, a water inlet 7 provided on the upstream side of the electrolyzer 4, and a water outlet 8 provided on the downstream side of the electrolyzer 4. ing.

The control means 6 includes, for example, a CPU (Central Processing Unit) that executes various arithmetic processes and information processing, a program that controls the operation of the CPU, and a memory that stores various information.

Current detection means 44 is provided on the current supply line between the anode power supply 41 and the control means 6. The current detection unit 44 may be provided in a current supply line between the cathode power supply 42 and the control unit 6. The current detection unit 44 detects the electrolysis current I supplied to the

power feeding bodies

41 and 42 and outputs a signal corresponding to the value to the control unit 6.

The control means 6 performs feedback control of the voltage applied between the anode power supply 41 and the cathode power supply 42 based on the signal input from the current detection means 44. For example, when the electrolysis current is excessive, the control unit 6 decreases the voltage, and when the electrolysis current is excessive, the control unit 6 increases the voltage. Thereby, the electrolysis current I supplied to the

power feeders

41 and 42 can be appropriately controlled.

The water inlet 7 has a water supply pipe 71, a flow rate sensor 72, a branching portion 73, a flow rate adjustment valve 74, and the like. The water supply pipe 71 is connected to, for example, a water purification cartridge (not shown), and guides water supplied with water purified by the water purification cartridge to the electrolysis chamber 40. The flow rate sensor 72 is provided in the water supply pipe 71. The flow rate sensor 72 periodically detects the flow rate per unit time of water supplied to the electrolysis chamber 40 (hereinafter sometimes simply referred to as “flow rate”) F, and outputs a signal corresponding to the value F to the control means 6. Output to.

The branch part 73 branches the water supply pipe 71 into two directions of the

water supply pipes

71a and 71b. The flow rate adjusting valve 74 connects the

water supply pipes

71a and 71b to the anode chamber 40A or the cathode chamber 40B. The flow rate of water supplied to the anode chamber 40A and the cathode chamber 40B is adjusted by the flow rate adjusting valve 74 under the control of the control means 6. The flow rate adjusting valve 74 adjusts the flow rate of water supplied to the anode chamber 40A and the cathode chamber 40B in order to increase the use efficiency of water. This may cause a pressure difference between the anode chamber 40A and the cathode chamber 40B.

In the present embodiment, since the flow rate sensor 72 is provided on the upstream side of the branching portion 73, the sum of the flow rate of water supplied to the anode chamber 40A and the flow rate of water supplied to the cathode chamber 40B, that is, A flow rate F of water supplied to the electrolysis chamber 40 is detected.

The water outlet 8 includes a flow path switching valve 81, a water discharge pipe 82, a drain pipe 83, and the like. The flow path switching valve 81 selectively connects the anode chamber 40A and the cathode chamber 40B to the water discharge pipe 82 or the drain pipe 83. When the electrolyzed water generating apparatus 1 is used for generating a dialysate for hemodialysis, the electrolyzed hydrogen water generated in the cathode chamber 40B dilutes the reverse osmosis membrane module for filtration and the dialysate stock solution through the water discharge pipe 82. Supplied to a dilution device or the like.

The control means 6 controls the polarity of the DC voltage applied to the anode power supply 41 and the cathode power supply 42. For example, the control means 6 integrates the flow rate F of water supplied to the electrolysis chamber 40 based on a signal input from the flow sensor 72, and when it reaches a predetermined integrated value, the anode power supply 41 and the cathode power supply 42. The polarity of the DC voltage applied to is switched. Along with this, the anode chamber 40A and the cathode chamber 40B are interchanged. In switching the polarity of the DC voltage, the control means 6 operates the flow rate adjustment valve 74 and the flow path switching valve 81 in synchronization. Thereby, the cathode chamber 40B and the water discharge pipe 82 are always connected, and the electrolytic hydrogen water generated in the cathode chamber 40B is discharged from the water discharge pipe 82.

FIG. 2 is a perspective view before the electrolytic cell 4 is assembled. The electrolytic cell 4 includes a first case piece 50 on the anode power supply body 41 side, a second case piece 60 on the cathode power supply body 42 side, a first reinforcing member 110 attached to the outer surface of the first case piece 50, The second reinforcing member 120 is mounted on the outer surface of the two case pieces 60. The first case piece 50 and the second case piece 60 arranged to face each other are fixed to each other, so that the electrolysis chamber 40 (see FIG. 1) is formed therein.

The electrolytic cell 4 accommodates a laminated body 45 in which an anode power supply 41, a diaphragm 43 and a cathode power supply 42 are stacked in an electrolysis chamber 40.

The anode power supply body 41 and the cathode power supply body 42 are configured such that water can travel in the thickness direction. For the anode feeder 41 and the cathode feeder 42, for example, a net-like metal such as an expanded metal can be applied. Such a net-like anode power supply 41 and cathode power supply 42 can distribute water to the surface of the diaphragm 43 while sandwiching the diaphragm 43, and promote electrolysis in the electrolytic chamber 40. In the present embodiment, as the anode power supply body 41 and the cathode power supply body 42, one in which a platinum plating layer is formed on the surface of a titanium expanded metal is applied. The platinum plating layer prevents the oxidation of titanium.

The anode power supply body 41 is provided with a terminal 41 a that penetrates the first case piece 50 and protrudes outside the electrolytic cell 4. For example, a terminal 41f is attached to the terminal 41a via a sealing member 41b, a bush 41c, and nuts 41d and 41e. Similarly, the cathode power supply 42 is also provided with a terminal 42 a that penetrates the second case piece 60 and protrudes outside the electrolytic cell 4. For example, a terminal 42f is attached to the terminal 42a via a sealing member 42b, a bush 42c, and nuts 42d and 42e. The

terminals

41f and 42f are connected to the control means 6 shown in FIG. A DC voltage is applied to the anode power supply 41 and the cathode power supply 42 via the

terminals

41a, 42a and 41f, 42f.

In the electrolytic cell 4 having the diaphragm 43 using a solid polymer material, neutral electrolyzed water is generated. On both surfaces of the diaphragm 43, plating layers 43a made of platinum are formed. The plating layer 43a, the anode power supply 41, and the cathode power supply 42 are in contact with each other and are electrically connected.

The diaphragm 43 is sandwiched between the anode power supply 41 and the cathode power supply 42 in the electrolysis chamber 40. Therefore, the shape of the diaphragm 43 is held by the anode power supply 41 and the cathode power supply 42. According to such a structure for holding the diaphragm 43, most of the stress caused by the pressure difference generated between the anode chamber 40A and the cathode chamber 40B is borne by the anode feeder 41 and the cathode feeder 42. The stress on 43 decreases. Thereby, even if the electrolyzed water generating apparatus 1 is operated in a state where a large pressure difference is generated between the anode chamber 40A and the cathode chamber 40B, no large stress is generated in the diaphragm 43. Therefore, it is possible to suppress damage to the diaphragm 43 and easily increase the water use efficiency.

Further, since the diaphragm 43 is sandwiched between the anode power feeding body 41 and the cathode power feeding body 42, the contact between the plating layer 43 a and the anode power feeding body 41 of the diaphragm 43 and between the plating layer 43 a and the cathode power feeding body 42. The resistance is reduced and the voltage drop is suppressed. Thereby, electrolysis in the electrolysis chamber 40 is promoted by a sufficient electrolysis current I, and electrolytic hydrogen water having a high dissolved hydrogen concentration can be generated.

As shown in FIG. 2, the outer sides of the outer periphery of the anode power supply 41 and the cathode power supply 42 are sealed to prevent water leakage from the mating surfaces of the first case piece 50 and the second case piece 60. A stop member 46 is provided. The outer peripheral portion of the diaphragm 43 is sandwiched by the sealing member 46.

The

case pieces

50 and 60 are made of a resin such as ABS (acrylonitrile butadiene styrene) or PPS (polyphenylene sulfide). Each

case piece

50 and 60 is formed in a rectangular shape that is long in the vertical direction V along the flow of water in the electrolysis chamber 40. Accordingly, the electrolytic chamber 40 is formed in a rectangular shape that is long in the vertical direction V. Such a vertically long electrolytic chamber 40 makes the flow path in the electrolytic cell 4 long. As a result, the hydrogen gas generated in the cathode chamber 40B is easily dissolved in the water in the cathode chamber 40B, and the dissolved hydrogen concentration can be increased.

FIG.

As shown in FIGS. 3 and 4, a mating surface 51 for fixing the first case piece 50 and the second case piece 60 to the outer edges of the inner surfaces of the first case piece 50 and the

second case piece

60, 61 is formed. Inside the mating surfaces 51, 61, the inner walls are recessed from the mating surfaces 51, 61 in the thickness direction of the first case piece 50 and the second case piece 60, so that the

electrolysis parts

52, 62 are provided. The electrolysis unit 52 configures the anode chamber 40A, and the electrolysis unit 62 configures the cathode chamber 40B.

A plurality of first convex portions 53 are disposed on the inner surface of the first case piece 50. Each first convex portion 53 is arranged side by side in the horizontal direction H perpendicular to the vertical direction V, with the electrolysis portion 52 extending in the vertical direction V. On the other hand, a plurality of second convex portions 63 are arranged on the inner surface of the second case piece 60. Each of the second convex portions 63 is arranged side by side in the horizontal direction H with the electrolysis portion 62 extending in the vertical direction V. Such first convex portion 53 and second convex portion 63 do not hinder the movement of water flowing in the vertical direction V in the electrolysis chamber 40.

Each first convex portion 53 is in contact with the anode power feeding body 41 in the anode chamber 40A, and presses the anode power feeding body 41 toward the second case piece 60 side. On the other hand, each 2nd convex-shaped part 63 contact | abuts with the cathode electric power feeding body 42 in the cathode chamber 40B, and presses the cathode electric power feeding body 42 to the 1st case piece 50 side. Therefore, the laminated body 45 is sandwiched from both surfaces by the first convex portions 53 and the second convex portions 63. The shape and arrangement of the first convex portion 53 and the second convex portion 63 are arbitrary. For example, the first convex portions 53 and the second convex portions 63 are alternately arranged in the lateral direction of the electrolysis chamber with the laminate interposed therebetween as shown in FIG. Alternatively, as shown in FIG. 8 of the above-mentioned Patent Document 1, they may be arranged so as to face each other with the laminate interposed therebetween. Moreover, the 1st convex-shaped part 53 and the 2nd convex-shaped part 63 may be the form provided discretely in the vertical direction, as FIG. 9 and 10 of the said patent document 1 shows.

As shown in FIG. 2, the first reinforcing member 110 and the second reinforcing member 120 are attached to the outer surfaces of the

case pieces

50 and 60. In this embodiment, the 1st reinforcement member 110 and the 2nd reinforcement member 120 are comprised by carrying out sheet metal processing of metals, such as stainless steel, for example. The first reinforcing member 110 and the second reinforcing member 120 are fixed to the first case piece 50 and the second case piece 60 via screws 95 or the like. A female screw 119 corresponding to the screw 95 is formed in the first reinforcing member 110. Thereby, a nut etc. become unnecessary for joining with the 1st case piece 50 and the 2nd case piece 60, the number of parts of the electrolytic cell 4 can be reduced, and the productivity of the electrolytic cell 4 can be improved.

The first reinforcing member 110 reinforces the first case piece 50. The second reinforcing member 120 reinforces the second case piece 60. Since the first reinforcing member 110 and the second reinforcing member 120 suppress the deformation of the first case piece 50 and the second case piece 60, that is, the expansion of the electrolytic cell 4, the contact between the diaphragm 43 and the

power feeding bodies

41 and 42. The pressure is sufficiently secured, and the contact resistance between the diaphragm 43 and each of the

power feeding bodies

41 and 42 is reduced. Accordingly, a sufficient electrolysis current I can be easily obtained without excessively increasing the electrolysis voltage applied to each of the

power supply bodies

41 and 42, and the generation efficiency of hydrogen gas can be easily increased.

The electrolytic cell 4 is provided with L-shaped

joints

91, 92, 93, 94. The

joints

91 and 92 are attached to the lower part of the first case piece 50 and the second case piece 60 and connected to the flow rate adjusting valve 74. The

joints

93 and 94 are attached to the upper portions of the first case piece 50 and the second case piece 60 and connected to the flow path switching valve 81. By starting water flow to the electrolyzed water generator 1, a general flow of water is generated from the lower part to the upper part of the anode chamber 40A and the cathode chamber 40B.

The hydrogen gas generated in the cathode chamber 40B moves as a minute bubble above the cathode chamber 40B. In the present embodiment, the movement direction of hydrogen gas and the direction in which water flows generally coincide with each other, so that hydrogen molecules easily dissolve in water and the dissolved hydrogen concentration is increased.

FIG. On the other hand, FIG. 6A is a perspective view of the second reinforcing member 120 viewed from the inner surface side facing the second case piece 60 side, and FIG. 6B is a second reinforcing member 120 viewed from the outer surface side. FIG.

As shown in FIGS. 5 and 6, the first reinforcing member 110 includes a first base 111 formed along the outer surface of the first case piece 50, and a first upright formed from the first base 111. Part 112. Since the rigidity of the 1st reinforcement member 110 is improved by the 1st standing part 112, the expansion | swelling of the electrolytic cell 4 is suppressed further, and the generation efficiency of hydrogen gas further improves.

Similarly, the second reinforcing member 120 includes a second base portion 121 formed along the outer surface of the second case piece 60 and a second upright portion 122 formed upright from the second base portion 121. Since the rigidity of the 2nd reinforcement member 120 is improved by the 2nd standing part 122, the expansion | swelling of the electrolytic cell 4 is suppressed further, and the generation efficiency of hydrogen gas further improves.

The first upright portion 112 includes a first horizontal upright portion 113 extending along a horizontal direction H perpendicular to the vertical direction V, and a first end edge upright portion 114 extending along an edge of the first reinforcing member 110. . Similarly, the second upright portion 122 includes a second horizontal upright portion 123 extending along the horizontal direction H perpendicular to the vertical direction V, and a second end edge upright portion 124 extending along the edge of the second reinforcing member 120. Including. Such first reinforcing member 110 and second reinforcing member 120 can be easily formed by press-molding a metal plate.

For example, the first lateral upright portion 113 is formed by partially raising the first base portion 111. Accordingly, a through hole 115 is opened in the first base 111. In the present embodiment, a plurality of first lateral upright portions 113 and through holes 115 are arranged in the vertical direction V. A pair of first lateral upright portions 113 are formed at both ends in the vertical direction V of the through hole 115. Similarly, the second lateral upright portion 123 is formed by partially raising the second base portion 121. Accordingly, a through hole 125 is opened in the second base 121. The arrangement of the second laterally rising portion 123 and the through hole 125 is the same as that of the first laterally rising portion 113 and the through hole 115.

The first reinforcing member 110 is preferably formed with a first lateral upright portion 113 and a first end edge upright portion 114. Of the first lateral upright portion 113 and the first end edge upright portion 114, At least one of them may be formed. The first lateral upright portion 113 increases the bending rigidity of the first reinforcing member 110 in the lateral direction H, that is, the lateral direction, and further suppresses the expansion of the electrolytic cell 4. By the first edge rising portion 114, the bending rigidity in the vicinity of the edge of the first reinforcing member 110 is increased, and the expansion of the electrolytic cell 4 is further suppressed. The same applies to the first lateral upright portion 113 and the first edge upright portion 114.

The first reinforcing member 110 may be formed with a first vertical rising part extending in the vertical direction V instead of the first horizontal rising part 113. In this case, the bending rigidity in the longitudinal direction V, that is, the longitudinal direction of the first reinforcing member 110 is increased, and the expansion of the electrolytic cell 4 can be suppressed. Similarly, instead of the second lateral upright portion 123, a second vertical upright portion extending along the vertical direction V may be formed in the second reinforcing member 120.

As shown in FIG. 3, first ribs 54 are formed in the first case piece 50. The first rib 54 protrudes outward from the electrolytic cell 4 from the outer wall surface 50 a of the first case piece 50 of the electrolysis chamber 40.
