With such an electrolyzing water producing apparatus, water having a low PH value can be obtained by the acidic water discharged from the anode chamber, but it is difficult to continuously produce a large amount of electrolyzing water. Is. Generally, the electric conductivity (EC) of tap water in the suburbs of Tokyo is around 100 to 200 μS / cm and the PH is around 6.5 to 8, and in order to pass a large current to the electrolytic cell, the applied voltage should be raised. Although it has to be done, the increase in voltage may generate gas or discharge, which may damage the electrode surface. In addition, in order to increase the electric conductivity of the raw water, it is also possible to add salt solution to the raw water for electrolysis, but the fluctuation of the electric conductivity causes an increase or decrease in the electrolysis current, which stabilizes the electrolysis. Therefore, a large amount of electrolyzed water having a certain electrolytic characteristic, PH, electric conductivity, etc. was not obtained. In particular, the fluctuation was severe at the beginning of electrolysis when water supply was started.

Therefore, according to the present invention, acidic water having a high sterilizing effect of pH 3 or less, preferably about 1.5 to 2.6, can be stably obtained in a large amount with low power, and at the same time, alkaline water can be produced. The purpose is to generate electrolyzed water.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment of the drawings below.
In FIG. 1, the electrolytic cell 1 has a closed structure, and the inside of the chamber is divided by a diaphragm 2. A cathode chamber 31 having a cathode electrode 3 inserted into one side thereof and an anode electrode 4 inserted into the other side thereof are referred to as an anode chamber 41.
An electrolytic current is applied to the cathode electrode 3 and the anode electrode 4 from an electrolytic power source 5 that applies a predetermined set voltage. Also,
A supply port 1a leading to the cathode chamber 31 and a supply port 1b leading to the anode chamber 41 are provided in the upper part of the electrolytic cell 1, and raw water is supplied from each of these supply ports. In order to discharge the electrolyzed water, a discharge port 1c communicating with the cathode chamber 31 and a discharge port 1d communicating with the anode chamber 41 are formed above the electrolytic cell 1.

Tap water or the like is used as the raw water supplied to the electrolysis tank 1, and the raw water supplied under pressure from the tap of the water supply is brought to a predetermined water pressure from the strainer 6 by the pressure reducing valve 7. This water pressure adjustment is adjusted according to the measurement of the pressure gauge 8. The raw water whose water pressure has been adjusted is controlled to a required flow rate by a flow control valve 9 and a flow meter 10. The raw water whose water pressure and flow rate are adjusted in this way is supplied to the electrolytic cell 1, and the electric conductivity (EC value) is adjusted during the process.

The electrical conductivity is adjusted by adding and mixing a chlorine-based electrolyte aqueous solution. For example, salt is used as the electrolyte, and the salt solution 11 is stored in the tank 12, which is supplied to the saline injection device 14 by the metering pump 13. The water level in the tank 12 is monitored by the water level gauge 15. The supplied saline solution is quantitatively injected into the raw water passing through by the injection device 14. It is preferable that the injected saline solution is further stirred and mixed by a mixing device (not shown), and is supplied to the electrolytic cell 1 from the pipe 16 in a sufficiently mixed state.

The raw water to be supplied is split at the inlet of the electrolytic cell 1 and is supplied to the cathode chamber 31 from the supply port 1a and the other to the anode chamber 41 from the supply port 1b. The alkaline water electrolytically generated in the electrolytic cell 1 is discharged from the cathode chamber discharge port 1c, and the acidic water is discharged from the anode discharge port 1d. Alkaline water is connected to the discharge port 1c through the pipe 17, and acidic water is connected to the discharge port 1d through the pipe line 1.
It passes through 8 and flows out. Three-way valves 19 and 20 are provided in the middle of the pipelines 17 and 18, respectively, and the branched combined water is discharged from the combining pipe 21. A flowmeter 22 provided in the flow path 18 of the acidic water for measuring the split state, and an ORP sensor 23 provided in the flow path for measuring the oxidation-reduction potential of the acidic water,
Any of the detection signals is input to the CPU 24, each part is controlled by arithmetic processing, and a signal is displayed on the display plate 25.

The operation of the above apparatus will be described with reference to the flowchart of FIG. The flow chart illustrates a state in which the CPU 24 sequentially controls the measurement by the detector, the comparison calculation processing of the measurement signals, and the control by the comparison calculation processing. When you first open the tap of the water supply or drive the water supply pump to start water supply, the raw water is strainer 6, pressure reducing valve 7
The water pressure is controlled to a predetermined level. This water pressure is step 1
Measure the controlled water pressure in step 2 after starting with, and if the prescribed water pressure does not come out, go back with negative N,
If the water pressure is generated, the process proceeds to the affirmative Y to move forward, and the flow rate lower limit data Q ₁ stored in step 3 is selected. Compare the signal Q. Q of comparison result>
If Q ₁ is negative N, the flow proceeds to step 6 to open the flow control valve 9 to control the increase of the raw water flow rate, and if Q> Q ₁ is affirmative Y, in the next step 5, the flow rate upper limit data Q
₂ is selected, and in step 7, Q <Q ₂ is compared. Q <
If Q ₂ is negative N, the flow rate is too large, so step 8
At, the control valve 9 is narrowed to control the flow rate reduction. If Q <Q ₂ is affirmative, it means that the flow rate of raw water fluctuated at the start was stabilized within a predetermined set range. At this time, in the next step 9, salt water was added to the raw water supply. start. The electric conductivity of the raw water supply is adjusted and controlled by injecting saline solution.

The saline solution stored in the tank 12 is, for example, a solution of about 10%, and the solution is quantitatively supplied by the pump 13. The saline solution injecting device 14 performs a pulsed drip injection of saline solution into the raw water that is quantitatively controlled, or forms a venturi portion in the raw water flow path and injects a predetermined amount of salt water by negative pressure to keep the salt content constant. It is possible to make raw water with constant electric conductivity. The injected salt water flows into the electrolytic cell 1 in a state of being sufficiently stirred and mixed by a mixing device or the like, and is electrolyzed by energization between the electrodes 3 and 4.
The power supply between the electrodes 3 and 4 is controlled by the power source 5 which applies a predetermined set voltage. However, since the electrolysis increases the electrical conductivity by adding saline, a large current can be passed at a low voltage. It is easy, the power wattage can be reduced and a strong electrolysis effect can be easily exerted, and salt water can be added and mixed at a constant ratio by controlling the flow rate of raw water, and the electric conductivity of water can be controlled to a constant level. A stable and constant electrolytic action can be exerted by electrolysis.

The electrolysis in the electrolytic cell 1 is electrolysis through the diaphragm 2, and the cations due to the electrolysis are subjected to the electroosmotic action of collecting in the cathode chamber 31 and the anion in the anode chamber 41 through the diaphragm 2, and the anode chamber 41 is subjected to the electroosmosis. As a result, acidic water containing a large amount of anions such as Cl ^{− and} having a low PH value can be obtained. The acidic water is electrolyzed with a large amount of electricity per flow rate, so that the electrical conductivity is increased and the acidic water becomes a strong acidic water having a low PH value. On the other hand, alkaline water is generated in the cathode chamber 31 and discharged from the discharge port 1c to the outside through the pipe line 17. Further, the acidic water in the anode chamber 41 flows out through the conduit 18. Pipe lines 17, 1
The three-way valves 19 and 20 inserted in 8 join the drain pipe 21 for drainage.

An ORP sensor 2 is provided in the acid water outlet conduit 18.
3 is provided. The ORP sensor 23 detects the oxidation-reduction potential of the electrolyzed acidic water, and the detection signal is the CPU 24.
Is supplied to. Here, in step 10 of the flowchart of FIG. 2, the ORP lower limit value O ₁ is selected, and in the next step 11, the detection signal O from the ORP sensor 23 is compared, and if O> O ₁ is negative N, Step 8
The flow rate control valve 9 is controlled so as to narrow the flow rate, and the raw water supply amount is reduced by this control to reduce the flow rate of the anode chamber 4.
The quantity of electricity per flow rate of the water flowing through 1 can be increased, and the increase in the quantity of electricity enhances the strength of electrolysis and increases the redox potential. If O> O ₁ is affirmative in step 11, the ORP upper limit value O ₂ is selected * in the next step 12, O <O ₂ is compared in step 13, and if negative N, the process proceeds to step 6. The valve 8 is controlled so as to return and the valve 8 is widened to increase the flow rate of the raw water and reduce the amount of electricity with respect to the flow rate so that a predetermined amount of electrolysis is performed. If the comparison of O <O ₂ is affirmative, the three-way valve 20 is opened in the next step 14 to control the use and outflow of the electrolytic acid water.

The arithmetic processing and control state by the CPU 24 at each step can be displayed and displayed on the display plate 25 every moment, and the ORP sensor 23, the flow meters 10, 22 and the water level meter 15 etc. can be notified to the CPU 24. The detection measurement signal is input from and is displayed on the display plate 25.

As described above, salt water is not added during the fluctuation of the flow rate of raw water after starting the supply of raw water. On the other hand, the mixing ratio of the saline solution, which is supplied in a fixed amount, is controlled to be constant by controlling the flow rate, and the raw water whose electric conductivity is constantly controlled is supplied to the electrolyzer 1 for electrolysis, so that a low-voltage and large-current electrolysis action is achieved. It is possible to stably give electrolytic water, and it is possible to generate electrolytic ion water with extremely high efficiency and stable electrolysis. Further, although the amount of electricity per flow rate changes depending on the flow rate of raw water flowing in the electrolytic cell 1, the amount of electricity can be controlled by controlling the flow rate, and constant and stable electrolysis can be performed. Then, the redox potential of the electrolytic discharge water is set to O
While being detected by the RP sensor 23, the flow rate is finely controlled so that it falls within the set range and electrolysis is performed, so that electrolyzed water controlled in a predetermined manner can be stably obtained. Also ORP sensor 2
Based on the measurement of 3, the three-way valve 20 was opened to allow the acidic water to flow out, so that the degree of electrolysis, that is, the redox potential, the electric conductivity, the PH value, the ion concentration, etc., were within the predetermined setting ranges. Only certain electrolyzed water can be stably taken out.

FIG. 3 shows another embodiment of the electrolytic cell 1, in which the diaphragm 2 is used.
The central part is the cathode chamber 31, the outside is the anode chamber 41,
Further, the outside thereof is divided into a cathode chamber 31, the cathode electrode 3 and the anode electrode 4 are inserted into each chamber, and a water supply pipe 16 for supplying raw water whose flow rate is controlled is branched 16a, 16b on the way,
The branch pipe 16a is used as the anode chamber 41, and the branch pipe 16b is used as the cathode chamber 3
1, the anode chamber 41 is connected to the pipe 18 and the cathode chamber 31 is connected to the pipe 17 to discharge electrolyzed water. Further, the salt water supply is added by the injection device 14 provided in the branch pipe 16b. The amount of saline solution supplied is 1 saline solution in the tank 12.
1 is supplied quantitatively according to the opening / closing degree of the valve 131. According to this apparatus, since the added supply of saline is supplied from the branch pipe 16b to the cathode chamber 31 in the electrolytic cell 1, the electrolytic reaction is promoted in the cathode chamber 31 and the anode chamber 41 side is highly efficient. Strong acidic water is produced. Further, since only the raw water is supplied to the anode chamber 41, the electrode consumption is extremely reduced, and the electrolysis efficiency can be improved.

The control of the CPU 24 for controlling the flow rate of the raw water supplied to the electrolytic cell 1 is performed by changing the reference set value to control the flow rate of the raw water in accordance with the change of the reference set value. For example, the amount of electricity per flow rate of flowing water can be increased. By increasing the amount of electricity, the electrolysis strength can be increased, and strongly acidic water with high PH and low PH value can be obtained. Water is obtained. This electrolyzed water generation is exactly the same when the three-way valve 19 is opened and the alkaline water is discharged to be used as drinking water or the like. By controlling the flow rate, a stable alkaline water can be efficiently produced in a large amount, and the pH can be arbitrarily controlled. Can generate water.
It should be noted that the ORP sensor 23 is used to generate the alkaline water.
Can be provided in the outlet 17 of the alkaline water, and a flow meter 22 can be provided.

The electrolysis condition is as described above except that the degree of electrolysis of the electrolyzed ion water discharged from the electrolysis tank 1 is measured.
It can also be measured by detecting the electrolysis voltage, electrolysis current, impedance change, and other change components during electrolysis. FIG. 4 shows an embodiment for detecting a change in electrolytic current.
A signal is added to the comparator amplifier 26. That is, the detection resistor 27 is inserted in a circuit for passing an electrolytic current between the power source 5 and the negative and positive electrodes 3, 4, the voltage signal dropped by the flowing current is applied to the-signal terminal of the comparator 26, and the diode 28 is applied to the + terminal. And the reference voltage set by the resistor 29 is applied and compared, so that the comparison amplified signal is sent to the CPU 2
Enter in 4. The CPU 24 detects the electrolysis state in the electrolysis tank 1 by the determination of the input signal, and controls the flow control valve 9 so that the electrolyzed water by the set electrolysis is always obtained. This makes it possible to generate acidic water and alkaline water having a predetermined PH value and the like.

The detection control by the CPU 24 is performed by selecting either the signal from each sensor as described above or the signal from another sensor, or by processing each signal separately and outputting the control signal. Of course, it is possible to control each part by calculating the sum, difference, product, etc. of the signals of each sensor and outputting a control signal. For example, the flow rate of the acidic water is detected by the flow meter 22 provided in the conduit 18, and the flow rate of the alkaline water is measured by the flow meter 10-flow meter 22 so that each flow meter 1
The flow rate can be controlled by measuring signals 0 and 22.

The control by the CPU 24 controls not only the above-described control at the start of electrolysis but also the flow rate control based on the detection signal from each sensor during the continuous generation of electrolyzed water. For example, not only the detection control of the ORP sensor 23, if the EC difference before and after electrolysis by the EC sensor is larger than the set value, the current state is maintained, and if it is smaller than the set value, the flow control valve 9
By controlling so as to reduce the flow rate of raw water into the electrolytic cell 1, the electrolytic action in the cathode chamber 31 and the anode chamber 41 is controlled by increasing the amount of electricity with respect to the flow rate, thereby giving a strong electrolytic action. The electric conductivity of alkaline water and acidic water discharged from the discharge ports 1c and 1d is increased.

Further, the mixing amount of the saline solution, which is quantitatively added by the injection device 14, is relatively increased due to the decrease of the raw water flow rate, whereby the electrolytic action is enhanced, and the production of the bactericidal agent such as hypochlorous acid is thereby caused. Can be increased. Therefore, by continuing the detection control of the CPU 24, required electrolyzed water having stable electric conductivity, PH value and the like can be continuously obtained from the outlet pipes 17 and 18 communicating with the electrolytic cell 1.

When water is passed through the electrolytic cell for electrolysis as described above, by adding salt water to the raw water for electrolysis, the electrolysis current easily flows and a strong electrolysis action due to a large current can be exerted at a low voltage. Therefore, the electric conductivity of the electrolytically discharged water can be increased. Further, the flow rate of the raw water to the anode chamber 41 can be arbitrarily controlled by a constant power source without controlling the power source by controlling the flow rate by the forward / reverse control of the flow rate control valve 9, thereby increasing the electrolysis degree of the acidic water and conducting the electricity. You can increase the degree. This increase in electrical conductivity correlates with a decrease in PH value, and it is possible to easily produce the target acidic water having a low PH value. In addition, the strong electrolysis action increases the redox potential of water and imparts a strong bactericidal effect. Even in the production of alkaline water, the drinking water having an arbitrary PH value can be efficiently produced by controlling the flow rate.

Explaining an experimental example, 100 l of raw water was mixed at a mixing ratio of 1 l of 10% saline, and the mixed raw water was supplied to an electrolytic cell for electrolysis. The conditions for energizing the electrolytic cell were 16 V and 30 A, and the flow rate of raw water flowing into the cathode chamber and the anode chamber was controlled so that pH 2.6 acidic water was 3.6 per minute.
1 was obtained. The PH value was stable from the beginning of electrolysis. For the purpose of comparison, when the acidic water was produced by controlling the voltage of the electrolytic cell, about 1 kW of electric power was consumed to produce 1 liter of acidic water.

As described above, according to the present invention, the required low PH is obtained.
A stable amount of acidic water can be obtained, and a large amount can be easily produced continuously. Further, when the pH value of the generated acidic water is raised to above pH 2 and 6 to be about PH3, it is sufficient to increase the flow rate, and further increase the generated amount of acidic water by controlling the flow rate to the required amount of electricity. You can Although the production of acidic water has been described above, the same applies to the case of using alkaline water, and the pH control of alkaline water can be facilitated by controlling the flow rate. Also in this case, a large amount of alkaline water can be easily obtained with a low electricity amount.

The flow rate may be controlled on the discharge water side, and the flow rate control means is provided in the discharge water flow path of the acidic water or the alkaline water. The flow rate control may be analog control, but digital control can be performed more easily, and stable precision control can be performed by pulse control by a motor valve or frequency control by a vibration valve. In addition to NaCl, the chlorine-based electrolyte added to raw water is KCl, HCl,
HClO, HClO ₃ , KClO ₃ , NaClO ₃ or the like can be used alone or in combination, and used as an aqueous solution of a predetermined concentration so that it can be uniformly mixed at a constant concentration with respect to the flow rate of raw water. The aqueous solution can be packed in a cylindrical container or the like and used as a cartridge. This injection can also be accurately controlled by injecting pulses in a pulse manner.

[0028]

As described above, according to the present invention, the electrolysis of water is facilitated by mixing the electrolyte, the wattage of electricity is reduced, and a large amount of electrolyzed water can be continuously obtained at a low cost. Further, by controlling the flow rate of the raw water, the amount of the electrolyte added and mixed by the metering pump and the amount of electrolysis electricity by the electrolysis power source of the set voltage can be arbitrarily controlled to predetermined values. Then, after starting the generation of electrolyzed water, when the raw water flow rate reaches a predetermined value by measurement with a flow meter, electrolyte water is added and mixed to obtain a predetermined electric conductivity at a predetermined mixing ratio, and in the electrolytic cell While controlling the flow rate by the sensor detection of the electrolysis state or the electrolysis degree of the electrolysis discharge water, the valve of the outlet line of the acidic water or the alkaline water was opened to let it flow out while it was controlled to a predetermined value. It is possible to stably take out only the electrolyzed water whose electric conductivity, PH value and the like are continuously controlled within a predetermined set range from the start. Also,
The electric conductivity and pH of the electrolyzed water can be easily adjusted by controlling the flow rate of the raw water, and acidic water of PH3 or less can be stably and easily produced. Further, by mixing chlorine, it is possible to easily generate acidic water having a high sterilizing effect for cleaning, which contains a large amount of chlorine, hypochlorous acid, or highly sterilizing oxygen in water. In addition, the apparatus configuration is such that the flow rate control means controls the flow rate of the raw water or the discharge water based on the detection of the flow meter and the electrolytic degree detection sensor. Since no control is performed, there is an effect that it becomes extremely simple and a large amount of electrolyzed water can be easily obtained.
