Description

Specification

Electrolytic hydrogen water generator

Technical field

[0001] The present invention relates to an electrolytic hydrogen water generating apparatus having a sterilizing function, which is equipped with an activated carbon block capable of adsorbing and holding organic pollutants contained in tap water.

Background art

Conventionally, an electrolytic hydrogen water generator of FIG. 2 (hereinafter referred to as a conventional device) shown in Japanese Patent Application Laid-Open No. 2006-43610 is known.

[0003] This conventional apparatus is equipped with an electrolytic cell 3 equipped with electrodes 1 and 2 for electrolysis, organic chlorine compounds such as residual chlorine and trihalomethane, 2-methylisoborneol that causes mold odor, and organic pollution such as agricultural chemicals. It consists of a filtration unit 6 equipped with an activated carbon block 4 that has the ability to adsorb and retain substances. The electrolysis electrodes 1 and 2 are supplied with a DC voltage from the power supply unit 7 to electrolyze the water stored in the apparatus to generate electrolytic gas such as hydrogen and oxygen, and when the water flow is stopped, Electrolytic gas is stored in In the power supply 7 that feeds the electrodes 1 and 2, the electrolytic current is detected by the current sensor 9 and fed back to the regulator 10 in order to maintain electrolysis that is not affected by fluctuations in water quality. Constant current control is used to keep it constant.

In addition, a polarity reversing circuit is provided to prevent mineral components such as calcium in tap water from precipitating on the cathode surface.

[0004] The polarity of electrodes 1 and 2 is reversed by opening and closing transistors S1A, S1B and S2A, S2B provided in power supply unit 7 at the same timing.

When the transistors S1A and S1B are opened and S2A and S2B are closed and DC voltage is supplied from the power supply unit 7, the electrolysis of water starts with the electrode 1 serving as the anode and the electrode 2 serving as the cathode, once every few hours. Transistors S1A and S1B are closed, S2A and S2B are switched to open, and electrolysis continues with electrode 1 as the cathode and electrode 2 as the anode. Electrolysis for several hours may deposit calcium on the cathode surface, but the polarity is reversed, and a large amount of hydrogen is generated on the electrode surface to generate acidic water in which calcium dissolves. [0005] Further, in the vicinity of the electrodes 1 and 2, a sterilizing electrode 26 made of titanium that constantly supplies a negative voltage to the electrode 1 or 2 is provided independently. When the impedance between the two electrodes is Z2, the ratio of the electrolysis current and the current required for titanium elution is Z1 while maintaining the same impedance Z1 between the electrodes 1 and 2 and the titanium electrode 26 constituting the electrode pair. , Electrode pairs 1 and 2 and bactericidal electrode 26 are arranged so that Z2 can be constructed. In a conventional electrolytic hydrogen generator, the sterilizing electrode 26 is always used as a cathode, and a very small amount of titanium is eluted by passing a weak current between the anode 1 and the electrode 2 serving as the anode. Therefore, the generation of bacteria in the activated carbon block 4 in the equipment and the latter stage is suppressed.

The sterilizing electrode 26 is always supplied with a negative DC voltage from the power supply unit 7 to the electrode 1 or the electrode 2.

[0006] In general water treatment equipment that requires an adsorbent material such as activated carbon for the purpose of purifying water, the raw material is activated charcoal with silver antibacterial action that has an antibacterial action in order to suppress the generation of bacteria in the adsorbent material filling section Technology (Patent Document 1) and activated carbon filter added with mineral sustained-release particles, and the technology that suppresses the growth of bacteria by the activated carbon filter power sustained release calcium and magnesium (Patent Document 2) are used. In Patent Document 3, a method of eluting titanium is used to suppress bacterial growth.

Patent Document 2: JP 2003-144821

Patent Document 3: JP 2006-43610

[0007] Furthermore, in Patent Document 3, activated carbon block 4 having the ability to adsorb organic pollutants formed by forming activated carbon powder into a hollow column shape using a binder such as polyethylene is formed, and an extremely fine size of about several μm is formed. An invention for providing pores is disclosed.

[0008] The electrolytic gas stored in the filtration unit 6 flows into countless pores of the activated carbon block 4 and the activated carbon powder, and the electrolytic gas is occluded in the activated carbon block 4.

As the internal pressure of the container increases due to the generation of electrolytic gas, the stored water permeates from the outer periphery of the activated carbon block 4 and oozes into the through hole 5 in the center, and the water supply pipe 16 force drains through the pressure adjustment valve 15. It is discharged as water.

[0009] When water tap 12 is opened and water is passed through, tap water is supplied to flow switch 13 and electrolytic water. Water is introduced to the filtration unit 6 through the tank 3, penetrates from the outer periphery of the activated carbon block 4, and is discharged from 5 through holes. At this time, the electrolytic gas occluded in the activated carbon block 4 comes into contact with tap water, and the electrolytic gas diffuses and dissolves in the water.

If electrolysis is continued, the water stored in the filtration unit 6 and the electrolytic cell 3 is completely replaced with electrolytic gas, and the electrodes 1 and 2 are exposed to the electrolytic gas layer 17. If for some reason the electrodes 1 and 2 are short-circuited, not only is the wasted power that is not consumed by the electrolysis lost, but also an electrolytic gas composed of high-concentration hydrogen gas and oxygen gas is generated when the short-circuit occurs. (Spark) may cause ignition or explosion. In order to prevent such a danger, electrolysis is started by starting power supply from the power supply unit 7 to the electrodes 1 and 2 by the activation signal from the flow switch 13 at the start of water flow. The timer 11 is configured to automatically stop the power supply from the power supply unit 7 for a certain period of time before being exposed to the gas.

As an alternative to the timer control method described above, a water level sensor such as a float switch is provided in the upper part of the electrolytic cell 3 or the lower part of the filtration unit 6 so that the electrolytic cell 3 is always filled with stored water. A method of controlling the power supply of the power supply unit 7 with a water level sensor is sometimes used.

[0011] After the electrolysis is stopped, when the water tap 12 is opened and tap water is introduced into the electrolytic hydrogen water generator, the start signal of the flow switch 13 is input to the power unit 7, and electrolysis starts again. The

[0012] Chemical reaction generated by electrolysis of water is shown in Chemical Formula 1.

[0013] Equation (1) represents the cathodic reaction, equation (2) represents the anodic reaction, and equation (3) represents the reaction of the entire system based on the above equations (1) and (2).

As expressed in Eq. (3), the electrolysis gas generated by the electrolysis of water is composed of hydrogen gas volume: oxygen gas volume ratio of 2: 1. Gas is stored It ’s hard to stay. In addition, extremely fine pores with a gap between the activated carbon powder constituting the activated carbon block 4 and the binder of about several / zm are formed, and the activated carbon powder surface, which is a component, has numerous pores on the order of nm to m. Have. For this reason, the electrolytic gas stored in the activated carbon block 4 is mixed with tap water and pushed out as fine bubbles from the activated carbon block 4, resulting in the generation of high-concentration hydrogen water.

Disclosure of the invention

Problems to be solved by the invention

[0014] In the above-described conventional electrolytic hydrogen water generator, the electrode for electrolysis has a polarity reversal circuit so that a large amount of hydrogen is generated on the electrode surface when calcium is attached when a negative voltage is applied. It can be removed by dissolving with water containing ions, so-called acidic water, but the sterilization electrode is always applied with a negative voltage, so long-term operation and the hardness of tap water are high! There was a problem that the electrolytic current decreased due to the accumulation of mineral components such as calcium on the surface. As the electrolysis current decreases, the amount of titanium elution from the sterilization electrode decreases, making it difficult to obtain a stable bactericidal effect. For example, an acidic solution such as citrate is prepared and cleaned regularly. Had to do.

Means for solving the problem

[0015] In order to solve the above-mentioned problem, in the electrolytic hydrogen water generating apparatus of the present invention, a water supply pipe, an electrolytic cell connected to the water supply pipe, a pair of electrolytic electrodes facing each other in the electrolytic cell, A sterilization electrode disposed above one of the electrolytic electrodes, a power source for supplying a positive or negative DC voltage to the pair of electrolytic electrodes at regular intervals, and the one electrode serving as a cathode. Only when the control means for supplying a negative voltage to the sterilization electrode above it, the filtration unit connected to the electrolytic cell and filtering the electrolyzed water and electrolytic gas generated in the electrolytic cell, and the filtration unit It consists of a water pipe that guides filtered water to the outside.

The electrolytic electrode is a conductive material that is not easily changed in electrical characteristics due to an oxidation reaction, such as platinum or a metal plated with platinum, and the sterilization electrode is made of titanium. In the gap between the electrolysis electrodes facing the sterilization electrode, acidic water generated in the vicinity of the anode is generated by the flow of oxygen bubbles generated when the electrolysis electrode disposed below the sterilization electrode becomes the anode. Introducing a guiding means, such as a separator The

[0016] Further, the subsequent filtration unit contains activated carbon blocks obtained by forming activated carbon powder into a hollow column shape using a binder such as polyethylene.

Furthermore, a control circuit for time-controlling the polarity of the power supply voltage and a power supply unit having a constant current function are provided outside, and power is supplied to the electrolytic electrode and the sterilization electrode of the electrolytic cell. The invention's effect

[0017] According to the electrolytic hydrogen water generator of the present invention, mineral components such as calcium deposited on the surface of the titanium electrode by weak electrolysis at the time of negative polarity are generated by electrolysis of water when the lower electrolysis electrode is at the anode. Acidic water can be dissolved and removed by inducing it near the titanium electrode for sterilization as the oxygen bubbles generated by electrolysis rise.

In addition, as a means for guiding the acidic water, for example, a shielding plate such as a separator is provided to prevent mixing of the electrolytic gas generated at each electrode, and to suppress a decrease in the acidity of the acidic water generated on the anode side. is doing.

In addition, when cleaning the titanium electrode, power supply to the titanium electrode is stopped, so that alkaline water is not generated, and the electrode cleaning efficiency with acidic water is improved.

[0018] By disposing the separator close to the titanium electrode, oxygen bubbles generated at the anode are concentrated and floated near the anode, so that the acidic water generated at the same time can be effectively removed near the titanium electrode. This can further improve the cleaning effect of mineral components such as calcium.

Example

FIG. 1 shows a configuration example of an electrolytic hydrogen water generator according to the present invention.

The apparatus comprises electrolysis electrodes 1 and 2 for electrolyzing water in the lower part to generate electrolysis gas 17, a sterilizing titanium electrode 20 disposed above electrode 2 so as to face electrode 1, Electrolytic cell 3 composed of separator 23 made of insulating material in gap 22 composed of electrode 1 and titanium electrode 20, and activated carbon block 4 in which powdered activated carbon is formed into a hollow column shape with a binder at the top. A filtration unit 6 is provided.

The electrodes 1 and 2 are made of platinum-plated metal such as titanium. The titanium electrode 20 for bacteria uses a titanium material as it is.

[0020] The separator 23 is provided with an electrode in order to prevent the bubbles of the electrolytic gas generated at the electrodes 1 and 2 from being mixed in both directions and reducing the acidity of the acidic water generated at the electrode 2. Titanium electrode 20 facing 1 is arranged so as to cover and hide the surface.

When a conductive material is used for separator 23, separator 23 acts as a floating electrode with a polarity opposite to that of electrode 2 for water electrolysis, so that the acidity of the acidic water generated at electrode 2 is reduced. Therefore, it is desirable that the separator 23 is made of an insulating material, or an insulating coating is applied even if it is a conductive material.

When a weak current is applied with the electrode 1 as an anode and the titanium electrode 20 as a cathode, if an insulator having a micropore such as an ion exchange membrane is used as the separator 23, the electrodes 1 and 2 It is also possible to reduce the supply voltage to the electrode 1 and the titanium electrode 20 while preventing the mixing of the electrolytic gas generated in step 1.

[0021] Fig. 3 and Fig. 4 show an example of the bactericidal effect of the eluted titanium.

In the example shown in Fig. 3, the electrode configuration of the present invention using titanium as the cathode and titanium plated with platinum, and the electrode configuration using titanium plated with platinum on both electrodes, After energizing water for 5 hours at 10 mA, where the current value (mA) multiplied by the current-carrying time (hour) is equivalent to 50 mA X hour (hereinafter abbreviated as mA'h), It shows the transition of the number of viable bacteria when.

In the electrode configuration using titanium plated with platinum at both electrodes, no decrease in the number of viable bacteria was confirmed, whereas in the electrode configuration of the present invention, a clear bactericidal effect was confirmed over time.

From the results, it can be seen that in the electrode configuration of the present invention, a small amount of titanium eluted with the cathode force remains in the water, so that the sterilizing effect is exhibited even when the water is turned off.

[0022] The example shown in Fig. 4 is equivalent to 50mA'h for 1L of water using titanium as the cathode and titanium with platinum plating on the anode, similar to the conditions in Fig. 3. Figure 5 shows the change in the number of viable bacteria when energized for 5 hours at 10 mA and general bacteria were added before energization. The number of viable bacteria decreases with the passage of time immediately after energization, and as described above, the decrease in the number of viable bacteria is confirmed even after energization is stopped. [0023] In addition, there is a possibility that the bactericidal effect can be improved by increasing the current value of the titanium electrode and increasing the titanium concentration. Since the growth of bacteria can be sufficiently suppressed if it is continuously used, the energization condition represented by the product of the current value and the energization time required for titanium elution is equivalent to 50 mA'h.

[0024] Fig. 5 shows the amount of titanium eluted with respect to the energization condition represented by the product of the current value and the energization time. The amount of titanium elution increased with the increase in the product of the current value and energization time, and the amount of titanium elution was about 10 ^_4 mg under the energization conditions of the present invention (equivalent to 50 mA'h for 1 L of stored water). titanium concentration of the stored water is estimated to be about 10 ^_4 mgZL.

[0025] Furthermore, the titanium electrode 20 is configured with an electrode area corresponding to the current ratio between the electrode 2 and the titanium electrode 20 in order to ensure a current-carrying condition in which the bactericidal effect of the eluted titanium is exhibited.

The energization conditions for exerting the above bactericidal effect are set so that the condition shown in Equation 1 is satisfied based on the results of the verification of the bactericidal effect of the eluted titanium described above.

(Formula 1)

I = 50mA-h XV / t

Where I is the conduction current (mA) of the titanium electrode, V is the amount of water stored in the electrolytic hydrogen water generator according to the present invention (L), and t is the power supply time to the titanium electrode (h ).

[0026] The surface area S2 of the electrode 2 and the surface area S1 of the titanium electrode are the impedance between the electrodes 1 and 2 as Z2, the distance between the electrodes as L2, the impedance between the electrodes 1 and the titanium electrode 20 as Z1, When the distance between the electrodes is L1, the electrolytic current required to generate the electrolytic gas is 12, and the current flowing through the titanium electrode is II, the relationship of Eq. (4) is established.

Therefore, the electrolytic current between electrodes 1 and 2 12, the distance L2 between electrodes, and the surface area S2 of electrode 2, the surface area S1 of titanium electrode 20 and the distance L1 between electrodes satisfy the relationship of Eq. (4). If it is configured like this, it is good.

The surface area S1 of the titanium electrode 20 does not indicate an apparent surface area corresponding to the total facing area of the titanium electrode 20, but indicates a true surface area that is undesirably applied to a weak current. The surface area S1 becomes / J, the smaller the material that changes depending on the form and uses a lower porosity. (Formula 2)

Z1XI1 = Z2XI2 (1)

Zl = XL1 / S1 (2)

Z2 = p XL2 / S2 (3)

I1XL1 / S1 = I2XL2 / S2 (4)

S2 / S1 = I2XL2 / (I1XL1) (5)

Note that p in Eqs. (2) and (3) indicates the specific resistance of water.

[0027] The power supply unit 7 that feeds a DC voltage to the electrodes 1 and 2 and the titanium electrode 20 includes a current sensor 9 that detects a current flowing through the electrodes 1 and 2 and the titanium electrode 20, and an output signal of the current sensor 9. A constant-current power supply is equipped with a regulator 10 that keeps the current value constant by varying the output voltage, and a timer 11 that stops voltage output at a predetermined time. In addition, the power supply circuit to the titanium electrode 2 is equipped with a diode 24, and energization is performed only at the cathode, and the power supply is stopped at the anode, thereby preventing a decrease in the energization performance due to oxidation of the titanium electrode 20.

[0028] The polarity of the electrodes 1 and 2 is reversed by opening and closing the transistors S1A, S1B and S2A, S2B provided in the power supply unit 7 at the same timing.

When the transistors S1A and S1B are opened and S2A and S2B are closed and DC voltage is supplied from the power supply unit 7, the electrolysis of water starts with the electrode 1 serving as the anode and the electrode 2 serving as the cathode, once every few hours. Transistors S1A and S1B are closed, S2A and S2B are switched to open, and electrolysis continues with electrode 1 as the cathode and electrode 2 as the anode. When electrode 1 or electrode 2 becomes a cathode, mineral components contained in the raw water, such as calcium, are deposited on the surface of the electrode, but electrode 1 or electrode 2 becomes an anode by the polarity switching function described above. Acidic water is generated near the electrode by hydrogen ions generated by electrolysis of water, and the calcium deposited on the electrode can be dissolved. When tap water containing a large amount of calcium is used, calcium precipitation at electrode 1 and electrode 2 can be suppressed by reducing the polarity switching time.

[0029] A negative voltage is applied to the titanium electrode 20 with the transistors S1A and S1B open and S2A and S2B closed, and a small amount of titanium is eluted to exert a bactericidal action. Under the condition that transistors S1A and SIB are closed and S2A and S2B are opened, power supply is stopped by diode 24. Note that calcium is deposited on the surface of the titanium electrode 20 during negative voltage feeding.

When power supply to the titanium electrode is stopped, a positive voltage is applied to the lower electrode 2, and oxygen bubbles, which are electrolytic gases, are generated by the reaction shown in Eq. (2) in (ii) 1 by electrolysis of water. And acid water is produced.

Oxygen bubbles rise to the top due to buoyancy, and at the same time, acidic water is efficiently guided to the vicinity of the titanium electrode 20 along with the flow of oxygen bubbles, so that the calcium deposited on the surface of the titanium electrode 20 is dissolved and removed. .

Furthermore, by disposing the separator 23 in the vicinity of the electrode 2 and the titanium electrode 20, diffusion of oxygen bubbles can be suppressed, and simultaneously generated acidic water can be efficiently guided to the surface of the titanium electrode 20. Can improve the cleaning effect of calcium deposited on the electrode surface

[0031] The electrolytic cell 3 including the electrodes 1 and 2 and the titanium electrode 20 configured as described above, and a DC voltage having a controlled polarity are applied to each of the electrodes, so that the filtration unit 6 and the lower part are disposed. The stored water in the electrolytic cell 3 is electrolyzed, and hydrogen and oxygen, which are the electrolysis gas 17, accumulate in the upper part of the filtration unit 6. At the same time, when electrode 2 and titanium electrode 20 are negative, a slight amount of titanium elutes and diffuses into the stored water. In addition, due to an increase in the internal pressure of the container due to the generation of the electrolytic gas 17, the stored water containing the eluted titanium permeates from the outer periphery of the activated carbon block 4 and oozes into the through-hole 5 in the center and passes through the pressure regulating valve 15. It is discharged from the water pipe 16 as drain water.

Through the process described above, the eluted titanium can sterilize the stored water and bacteria in the activated carbon block 4 and keep the device clean.

[0032] When the water tap 12 is opened and water is passed, the tap water is introduced to the filtration unit 6 via the flow switch 13 and the electrolytic cell 3, mixed with the stored electrolytic gas, and then activated carbon block 4 The outer peripheral force also penetrates and is discharged from the through hole 5. At this time, trace amounts of pollutants contained in tap water are removed, and the mixed electrolytic gas and the electrolytic gas occluded in the activated carbon block 4 are converted into fine bubbles by the activated carbon block 4, and the Provides high-concentration hydrogen water by diffusing and dissolving.

Next, FIG. 6 shows a configuration in which a titanium electrode is disposed above both electrolytic electrode pairs, using the above-described electrolytic cell structure according to the present invention as an application example.

In this equipment, titanium electrodes 31 and 32 are provided above both electrode 1 and electrode 2, and accordingly, a power supply circuit for applying a negative potential to both titanium electrodes 31 and 32 is provided. Except for this, the other components and operating conditions are the same as those of the device shown in Fig. 1 above.

[0034] Titanium electrode 31 is fed from electrode 1 and titanium electrode 32 is fed from electrode unit 2 with the polarity synchronized to electrode 2, and the output voltage is varied by current sensor 9 and regulator 10 to change the current value. Keep constant. At this time, only a negative potential is fed to the titanium electrodes 31 and 32, and therefore the diode 24 is provided in the feeding circuit to the titanium electrodes 31 and 32.

[0035] With the above configuration, when transistors S1A and S1B are opened and S2A and S2B are closed, electrode 1 functions as an anode, electrode 2 and titanium electrode 32 function as a cathode. Mineral components such as calcium are deposited. When transistors S1A and S1B are closed and S2A and S2B are opened, electrode 2 acts as the anode, electrode 1 and titanium electrode 31 act as the cathode, and calcium is deposited on the surface of titanium electrode 31. At this time, oxygen bubbles 25 and acidic water are generated at electrode 2 by electrolysis of water. Acidic water is guided to the vicinity of the titanium electrode 32 as the oxygen bubbles 25 rise, and dissolves and removes calcium deposited on the titanium electrode 32. Calcium deposited on the titanium electrode 31 is dissolved and removed by the acidic water generated at the electrode 1 after polarity reversal.

[0036] By using the electrolytic hydrogen water generator of the present invention described above in detail, the titanium electrode is always kept clean even during long-term use, and stable energization performance can be secured. Therefore, it is possible to stably supply safe hydrogen water with little bacterial contamination.
