Description

  The present invention relates to a component-concentrated electrolyzed water generating device that can ionize seawater and continuously supply alkaline electrolyzed water and acidic electrolyzed water, and in particular, alkaline electrolyzed water and acidic electrolyzers by interposing an ion exchange membrane or the like in the electrolytic cell. The present invention relates to a component concentrated electrolyzed water generating device of a type that separates and generates electrolyzed water.

  As an alkaline ionized water device that continuously generates alkaline ionized water and acidic ionized water from tap water, an ion exchange membrane is interposed between the positive and negative electrodes, Some are separated into acidic ionic water. Moreover, as such an alkaline ionized water device, there is a type in which water is taken from a water supply currant (faucet), alkaline ionized water and acidic ionized water are discharged from a dedicated outlet, and the main body is installed on a sink. . In addition, there is a so-called built-in type in which the main unit is installed in the undersink, but this has a dedicated curan for taking water and discharging water, and discharges alkaline ionized water from a dedicated water outlet separate from the water supply curan. To do.

  Among these, a built-in type alkaline ion water conditioner (see, for example, Patent Document 1) allows tap water to flow from the raw water pipe when the user opens the faucet of the raw water pipe connected to the alkali ion water conditioner. Is supplied to an electrolytic cell, and alkaline water and acidic ion water are generated in this electrolytic cell. And while the alkaline water produced | generated by the electrolytic vessel is discharged through a water discharge pipe, acidic ion water is drained through an acid ion water discharge pipe.

  Alkaline ion water produced by an alkali ion water conditioner has been recognized as useful to the human body and is effective for drinking for chronic diarrhea, indigestion, abnormal fermentation in the gastrointestinal tract, antacid, and excessive gastric acidity. In addition, acidic ionized water is used in cosmetics as a weakly acidic astrigent.

  When alkaline ionized water is generated from tap water using such an alkaline ionizer, the current does not flow so much even if a large voltage is applied between the electrodes because the electrical conductivity of tap water is small. The tap water can be electrolyzed without damaging the electrodes constituting the alkaline ionized water device by the current. In addition, in such an alkaline ionized water device, a large voltage can be applied for the same reason, and therefore, Na ions, Ca ions, etc. present in tap water on the acidic ion water side by electrophoresis caused by the large voltage. As a result, the mineral component is drawn to the cathode side through the ion exchange membrane, and as a result, the alkaline ionized water in which the mineral component is concentrated can be conditioned.

  However, when alkaline ionized water is produced from seawater having a salinity of 3.5% using such an alkaline ionized water device, tap water is not allowed to flow between the electrodes due to the large amount of electrolyte contained in the seawater. When a high voltage similar to that used in the electrolysis is applied, a large amount of current flows, causing damage to the electrodes and the like. Further, as shown in the equation (1), the ion movement speed u by electrophoresis is proportional to the applied voltage E. Therefore, the applied voltage is too low even when applying a low voltage that allows only a small current that does not damage the electrodes, etc., so electrophoresis does not occur so much and mineral components present in the seawater on the acidic ion water side As a result, the mineral component cannot be concentrated in the alkaline ionized water.

u = μeE (1)
Here, μe is an electrophoretic mobility specific to ions.

  On the other hand, as a method of producing alkaline water in which mineral components are concentrated from seawater, seawater is desalted with a reverse osmosis membrane (desalination treatment) to make fresh water, and then solid mineral components are added to the fresh water. There is one that adjusts the content ratio of mineral components. However, this method has a problem that it is too expensive.

  The best mode for carrying out the present invention will be described below with reference to the drawings. The description of the present embodiment is an exemplification, and the configuration of the present invention is not limited to the following description.

(Embodiment 1)
FIG. 1 is a schematic diagram of a mineral-concentrated electrolyzed water generating device that is an example of a component-concentrated electrolyzed water generating device according to Embodiment 1. As shown in FIG. 1, the mineral concentrated electrolyzed water generating apparatus 1 according to the present invention electrolyzes sodium chloride, calcium chloride, etc. contained in a part of seawater or seawater, and Na ions, Ca ions, etc. Of electrolytic water 20 for generating alkaline electrolyzed water and acidic electrolyzed water concentrated in water, raw water pipe 10 connected to the lower end side of electrolyzer 20 for supplying seawater, An alkaline electrolyzed water drain pipe 11, which is an alkaline electrolyzed water drainage channel for discharging alkaline electrolyzed water connected to the upper end of the alkaline electrolyzed water, and an acidic electrolyzed water connected to the upper end of the electrolyzer 20 on the acidic electrolyzed water side. It consists of an acidic electrolyzed water drain pipe 12 which is an acidic electrolyzed water drainage channel for discharging electrolyzed water.

  An ion exchange membrane 30, which is a diaphragm, is fixed in the electrolytic cell 20, and the inside of the electrolytic cell 20 is partitioned into two spaces 25 a and 25 b by the ion exchange membrane 30. In addition, an electrode 40 is provided in the space 25a on the acidic electrolyzed water side facing the ion exchange membrane 30 in the electrolytic cell 20, and three electrodes 41, 42, and 43 are provided in the space 25b on the alkaline electrolyzed water side. It has been. Furthermore, the electrode 40 is connected to the positive electrode of the DC power supply 90, and the electrodes 41, 42, and 43 are finally connected to the cathode of the same DC power supply 90, respectively, but the electrode 41 is connected to the DC power supply 90 via the resistor 51. The electrode 42 is connected to the cathode of the DC power supply 90 through the resistor 52 and the pulse generator 62, and the electrode 43 is connected to the cathode of the DC power supply 90 through the resistor 53 and the pulse generator 63.

  With such a configuration, the electrolyzed water can be electrolyzed by continuously applying a predetermined voltage in the region sandwiched between the electrodes 40 and 41 as the first electrode, and this region is the first region. 26. Further, in a region sandwiched between the electrodes 40 and 42 and the electrodes 40 and 43 that are the second electrodes, a mineral component contained in the electrolyzed water can be moved by electrophoresis by intermittently applying a predetermined voltage. This region is the second region 27. In the present embodiment, the second region 27 includes a first-stage second region 28 that is a region sandwiched between the electrodes 40 and 42 and a second-stage second region that is a region sandwiched between the electrodes 40 and 43. An area 29 is included.

  The pulse generators 62 and 63 convert a constant voltage applied from the DC power supply 90 into a pulsed voltage, and are particularly limited as long as the constant voltage can be converted into a pulsed voltage. Specifically, a transistor having a switching function for generating a fixed rectangular wave such as an IGBT inverter may be used, and a general switch may be used. Note that the periods of the pulsed voltages generated from the pulse generators 62 and 63 may be the same or different.

  The resistance values of the resistors 51, 52, and 53 are not particularly limited, but a voltage to be applied to a region sandwiched between electrodes connected to the resistors can be appropriately set depending on the resistance value. Since a voltage is continuously applied in the first region 26, only a small voltage that does not flow much current can be applied so as not to damage the electrode and the like when electrolyzing the electrolyzed water. 27, since a high voltage can be applied intermittently, positively charged ions such as hydrogen ions, Na ions, and Ca ions electrolyzed in the first region 26 are electrophoresed in the direction of the cathode, that is, the electrode 42, It can be moved in the direction of 43.

  On the other hand, when the potential difference between the electrode 41 and the electrode 42 is increased, a leakage current flowing from the electrode 42 to the electrode 41 may be generated. This is the same for the electrode 43 and the electrode 42.

  Therefore, in this embodiment, the resistors 51, 52, and 53 are configured so that the potential difference between the electrode 42 and the electrode 41 is not significantly increased and the potential difference between the electrode 43 and the electrode 42 is not significantly increased so that no leakage current is generated. The magnitude of the resistance value is set. That is, while preventing the occurrence of leakage current, a small voltage that does not flow much current is applied in the first region 26, and a voltage that is not so large is intermittently applied in the second region 28 in the first stage. In addition, the magnitude of the voltage applied to each region is larger than the second region 29> 1 in the second stage so that a larger voltage is intermittently applied in the second region 29 in the second stage. The magnitudes of the resistance values of the resistors 51, 52, and 53 are set so that the relationship of the second region 28 in the step> the first region 26 is satisfied. By setting in this way, leakage current between the electrode 41 constituting the first region 26 and the electrode 42 constituting the first-stage second region 28 is prevented and the first-stage second region 28 is prevented. The generation of leakage current between the electrode 42 constituting the second region 28 and the electrode 43 constituting the second-stage second region 29 can be prevented.

  Note that generation of leakage current can also be prevented by providing an interval between the electrode 41 and the electrode 42. That is, by sufficiently separating the gap between the electrode 40 and the electrode 42 to such an extent that no leakage current is generated, the leakage current can be prevented and the voltage applied to the electrode 42 can be sufficiently increased. In this case, the electrode 43 may be omitted. In addition, when the electrode 43 is omitted in this way, the electrode constituting the second region 27 in order to allow Na ions, Ca ions, etc. contained in the electrolyzed water to move sufficiently toward the electrode 42. It is preferable to make the length of 42 sufficiently long in the flow direction.

  The ion exchange membrane 30 will not be specifically limited if it is a cation exchange membrane which selectively permeate | transmits the mineral component etc. which are contained in seawater.

  The electrodes 40, 41, 42 and 43 are not particularly limited as long as a predetermined voltage can be applied.

  The DC power supply 90 is not particularly limited as long as it can supply predetermined power.

  Next, with reference to FIG. 2, the mechanism which concentrates a mineral component in this mineral concentration electrolyzed water generating apparatus 1 is demonstrated. FIG. 2 is an enlarged schematic view of a portion including the electrode 40 and the electrode 42 of the mineral concentrated electrolyzed water generating device 1 according to the first embodiment shown in FIG. First, in the second region 28 at the first stage sandwiched between the electrode 40 connected to the positive electrode of the DC power supply 90 and the electrode 42 connected to the cathode of the DC power supply 90 via the pulse generator 62 and the resistor 52. When a pulsed voltage is applied, the electrode 40 is positively charged and the electrode 42 is momentarily charged with a negative charge. Then, a potential difference is generated between the electrodes 40 and 42, and positively charged ions 100a and 100b such as Na ions and Ca ions contained in seawater flowing between the electrodes 40 and 42 are electrophoresed. It moves so that the negative charge approaches the charged electrode 42. These positively charged ions 100a pass through the ion exchange membrane 30 and are attracted to the vicinity of the surface of the electrode 42 together with 100b and the like. In this way, positively charged ions such as Na ions and Ca ions on the acidic electrolyzed water side can be moved to the alkaline electrolyzed water side, and the mineral component can be concentrated in the alkaline electrolyzed water. In addition, since a negative charge is charged only momentarily on the electrode 42, a large voltage is momentarily applied to the second region 28 of the first stage sandwiched between the electrodes 40, 42, Does not flow that much.

  Next, with reference to FIG. 1, operation | movement of the mineral concentration electrolyzed water generating apparatus 1 which concerns on this embodiment is demonstrated. As described above, in the mineral concentrated electrolyzed water generating apparatus 1 according to the present embodiment, seawater is supplied from the raw water pipe 10 to the electrolyzer 20, and the electrolyzed seawater is electrolyzed in the electrolyzer 20 to produce alkaline electrolyzed water and acidic electrolyzed water. After the mineral components and the like are concentrated in the seawater on the alkaline electrolyzed water side, the alkaline electrolyzed water is discharged to the alkaline electrolyzed water drain pipe 11 and the acidic electrolyzed water is discharged to the acidic electrolyzed water drain pipe 12. The

  Here, the seawater supplied from the raw water pipe 10 to the electrolytic cell 20 flows into the spaces 25 a and 25 b on both sides partitioned by the ion exchange membrane 30. First, since a predetermined voltage is continuously applied by the electrodes 40 and 41 in the first region 26 sandwiched between the electrodes 40 and 41, when the flowing seawater passes through the first region 26. Some of the seawater is ionized into hydrogen ions and hydroxide ions, and sodium chloride and calcium chloride contained in the seawater are ionized. In the present embodiment, since seawater always flows between the electrodes 40 and 41, bubbles generated on the electrode surface are swept away when a voltage is applied between the electrodes sandwiching the seawater. It is possible to prevent seawater ionization disturbance due to air bubbles, which makes it difficult to ionize seawater due to the fact that current does not flow easily due to the presence of air bubbles.

  Next, when seawater is further supplied from the raw water pipe 10, seawater containing hydrogen ions, Na ions, Ca ions, etc. generated in the first region 26 sandwiched between the electrodes 40, 41 is downstream. The provided second region 27 moves.

  And when the seawater containing those ions etc. reaches the 2nd area | region 27, in the 2nd area | region 27, the predetermined pulse-form voltage is intermittently applied by the electrodes 40 and 42 and the electrodes 40 and 43. Therefore, a current does not flow so much in the seawater, but a predetermined pulse voltage is intermittently applied. Then, when the seawater passes through the second region 27, the positively charged ions such as hydrogen ions, Na ions, and Ca ions are charged with negative charges by electrophoresis generated by a pulsed voltage. It moves through the ion exchange membrane 30 toward 42. Then, hydrogen ions, Na ions, Ca ions, and the like are concentrated in the seawater on the alkaline electrolyzed water side.

  In the present embodiment, the second region 27 is composed of a first-stage second region 28 and a second-stage second region 29, and 1 is provided downstream of the first-stage second region 28. Since the second-stage second region 29 for applying a pulse-like voltage higher than that of the second-stage region 28 at the stage is provided, the electric power generated by the pulse-like voltage applied at the second-stage 28 at the first stage is provided. In the electrophoresis, a pulse voltage that applies hydrogen ions, Na ions, Ca ions, and the like that could not be transferred to the seawater on the alkaline electrolyzed water side through the ion exchange membrane 30 in the second region 29 in the second stage. It can be moved to the alkaline electrolyzed water side by electrophoresis.

  Then, the alkaline electrolyzed water in which hydrogen ions, Na ions, Ca ions, and the like are concentrated is discharged into the alkaline electrolyzed water drain pipe 11.

  As described above, according to the mineral-concentrated electrolyzed water generating device 1 according to the present embodiment, seawater is divided into an alkaline electrolyzed water side and an acidic electrolyzed water side, mineral components contained in the acidic electrolyzed water side, and the like. Can be concentrated to the alkaline electrolyzed water side, so that alkaline electrolyzed water in which mineral components contained in the seawater are concentrated in the vicinity of 2 times from seawater can be continuously generated.

  In the first embodiment, the electrodes 42 and 43 are connected to the cathode of the DC power supply 90 and the electrode 40 is connected to the positive electrode of the DC power supply 90 via the resistors 52 and 53 and the pulse generators 62 and 63. The polarity of 90 may be reversed, that is, the electrodes 42 and 43 may be connected to the positive electrode of the DC power supply 90 and the electrode 40 may be connected to the cathode of the DC power supply 90 via the resistors 52 and 53 and the pulse generators 62 and 63. . Also in this case, alkaline electrolyzed water in which mineral components and the like are concentrated can be generated, but the generated alkaline electrolyzed water is discharged from the acidic electrolyzed water drain pipe 12.

In the first embodiment, as described above, the resistors 52 and 53 and the pulse generators 62 and 63 are used to change the voltage applied to the second region 28 in the first stage and the second region 29 in the second stage. However, when the magnitude of the pulse voltage applied to the second region 28 at the first stage and the second region 29 at the second stage may be the same, as shown in FIG. Alternatively, only the pulse generators 62 and 63 may be provided between the DC power supply 90 and the DC power supply 90 so that the same voltage is applied to the second region 28 in the first stage and the second region 29 in the second stage.
