Description

  The present invention relates to a mixer for producing electrolyzed water by mixing an electrolyzed product produced by electrolysis of an aqueous electrolyte solution and source water, and electrolyzed water comprising such a mixer and an electrolyzer. The present invention relates to a generation device.

  For example, in the following patent document, dilute hydrochloric acid supplied to an electrolytic cell from a dilute hydrochloric acid tank is electrolyzed to generate hypochlorous acid water, and the generated hypochlorous acid water and water in a storage tank are mixed. Thus, an invention of an electrolyzer for generating hypochlorous acid water (hereinafter also simply referred to as “electrolyzer”) that generates hypochlorous acid water having a desired concentration is disclosed. In this case, in this electrolysis apparatus, the electrolytic cell is connected to the intermediate part of the circulation line connected to the storage tank. Further, in this electrolysis apparatus, the hypochlorous acid water generated in the electrolytic cell is mixed into the water in the circulation line via the mixing line, so that the connection site with the mixing line in the circulation line is “ A configuration in which hypochlorous acid water and water are mixed by functioning as a “mixer” is employed.

JP 2012-115749 A (page 3-5, Fig. 1-3)

  However, the electrolysis apparatus disclosed in the above patent document has the following problems. That is, in the above electrolysis apparatus, hypochlorous acid water generated in the electrolytic cell is mixed into the water in the circulation pipe, thereby mixing the hypochlorous acid water and the water so as to have a desired concentration of hypochlorous acid. The structure which produces | generates acid water is employ | adopted. In this case, in this electrolysis apparatus, the inside of the electrolytic cell (electrolytic treatment space) and the inside of the circulation pipe line are always in communication with each other through the mixing pipe line. Therefore, in this electrolyzer, the pressure in the circulation line applied by the circulation pump to pump water from the storage tank directly acts in the mixing line. Therefore, in this electrolyzer, a part of the water pumped into the circulation pipe by the circulation pump may enter the electrolytic cell (electrolytic treatment space) through the mixing pipe.

  In such a case, the amount of hypochlorous acid supplied in the electrolytic cell to the circulation line due to water intrusion into the mixing line (liquid flows back in the mixing line) Decreases, making it difficult to produce the desired concentration of hypochlorous acid. In addition, dilute hydrochloric acid supplied from the dilute hydrochloric acid tank into the electrolytic cell is diluted with water that has entered the electrolytic cell through the mixed conduit, resulting in a decrease in electrolysis efficiency in the electrolytic cell, and In this case, the amount of hypochlorous acid water to be mixed with water per unit time is reduced, or the concentration of the generated hypochlorous acid water is reduced. For this reason, the electrolysis apparatus disclosed in the above-mentioned patent document has a problem that it takes a long time to generate hypochlorous acid water having a desired concentration and the power consumption is increased.

Moreover, in the electrolyzed water generating apparatus of Claim 3, it is comprised so that the electrolyzed water can be produced | generated by providing said mixer and an electrolytic vessel.

  Therefore, according to the mixer according to claim 1 and the electrolyzed water generating device according to claim 3, due to the presence of the partition portion provided with the communication hole, from the upstream space where the source water is introduced from the first introduction port. However, since the pressure in the downstream space into which the electrolytic product from the electrolytic cell is introduced can be sufficiently reduced, the situation where the source water enters the electrolytic cell through the second inlet is suitably avoided. be able to. Thereby, according to this mixer and the electrolyzed water generating device, it is possible to avoid the situation where the aqueous electrolyte solution in the electrolytic cell is diluted with the source water, and therefore the electrolysis efficiency of the aqueous electrolyte solution in the electrolytic cell can be sufficiently improved. And the amount of power required for electrolysis can be sufficiently reduced. In addition, since the ingress of source water from the mixer to the electrolytic cell is avoided, the electrolytic product generated in the electrolytic cell can be efficiently supplied from the electrolytic cell to the mixer. Water can be generated efficiently in a short time.

  Moreover, according to the mixer of Claim 2, and the electrolyzed water generating apparatus provided with such a mixer, by forming a plurality of communication holes in the partition part of the mixer, the source water from each communication hole The source water and the electrolysis product can be suitably agitated in the downstream space by the jet, and both can be suitably mixed.

  Hereinafter, embodiments of a mixer and an electrolyzed water generating device according to the present invention will be described with reference to the accompanying drawings.

  The electrolyzed water generating device 1 shown in FIG. 1 corresponds to an “electrolyzed water generating device”. As an example, an “electrolyte aqueous solution (electrolyzed water)” supplied from an electrolyzed water tank 2 is electrolyzed to produce “electrolyzed The “electrolyzed product” can be generated and stored in the electrolyzed water tank 3 by mixing the generated “electrolyzed product” with “source water”. In the electrolyzed water generating apparatus 1 of this example, as an example, “electrolyzed product” generated by electrolyzing water as an “electrolyte aqueous solution (electrolyzed water)”, saline, dilute hydrochloric acid, and the like is “source water”.

Further, a part of chlorine constituting the “gas component” reacts with water as the “liquid component”, thereby generating hypochlorous acid water in the electrolytic cell.

  However, the concentration of dilute hydrochloric acid used as the “electrolyte aqueous solution (electrolyzed solution)” and the electrolytic treatment conditions (units) for the “electrolysis product” generated by electrolysis, that is, the “mixed fluid” discharged from the electrolytic cell Depending on the amount of dilute hydrochloric acid supplied to the electrolytic cell per hour and the voltage value of the DC voltage applied to the electrode in the electrolytic cell, etc., the concentration of hypochlorous acid water as a “liquid component” (generated by electrolysis) How much of the chlorine reacts with water in the electrolytic cell) and the proportion of chlorine etc. in the “gas component” is different. Therefore, in this example, in order to facilitate understanding of the configuration of the electrolyzed water generating apparatus 1, chlorine, hydrogen, and oxygen contained in the “electrolyzed product” composed of the “mixed fluid” are not distinguished from each other. The hypochlorous acid water contained in the “electrolytic product” is referred to as a “gas component” and will be described below as a “liquid component”.

(See FIGS. 4, 6, and 7) and an insertion hole 32 (see FIGS. 4 and 5) through which the connection conductor 24 connected to the electrode plate 23 accommodated in the electrolytic treatment space S1 can be inserted.

In addition, in the electrolytic cell 10 (mixing unit 10b) of this example, the opening on the mixing unit side container body 21b side in each supply hole 31 formed in communication from the processing tank side container body 21a to the mixing unit side container body 21b is provided. It corresponds to a “second inlet”.

As shown in FIGS. 6 and 7, the partition portion 21c is provided with a communication hole 37 (an example of “communication hole”) that allows the upstream space S4a and the downstream space S4b to communicate with each other. The passage of tap water from the space S4a to the downstream space S4b is allowed. In this case, in the electrolytic cell 10 (mixing part 10b) of this example, as shown in FIG. 6, the four communicating holes 37 are opened by the partition part 21c.

  Moreover, in the electrolytic cell 10 (mixing part 10b) of this example, as shown in FIG. 7, each for introducing the "electrolysis product" produced | generated in the electrolytic cell main body 10a into the mixing process space S4 of the mixing part 10b. Supply holes 31 are respectively opened in the downstream space S4b. Thereby, in the electrolytic cell 10 (mixing part 10b) of this example, the "electrolysis product" supplied from the electrolytic cell main body 10a is introduce | transduced in the downstream space S4b in the mixing process space S4.

  The lid body 22 is a member that closes the opening of the treatment tank side container body 21a in the container body 21 and forms the electrolytic treatment space S1 together with the treatment tank side container body 21a. As shown, an introduction hole 33 for introducing dilute hydrochloric acid supplied from the electrolyzed water tank 3 into the electrolytic treatment space S1, and a connection conductor 24 connected to the electrode plate 23 accommodated in the electrolytic treatment space S1 are provided. An insertion hole 34 that can be inserted is formed. In this case, in the electrolytic cell 10 (electrolytic cell main body 10a) of this example, the treatment tank side container body is mounted in the state where the lid body 22 is attached to the treatment tank side container body 21a containing the electrode plate 23 and the connecting conductor 24. The two are integrated by ultrasonic welding of the contact portion between 21a and the lid 22.

  As shown in FIG. 3, the electrode plate 23 is formed in a rectangular shape in plan view from a metal material having high corrosion resistance against hydrochloric acid or the like (for example, a titanium plate coated with a noble metal oxide such as platinum or ruthenium). In FIG. 3, only three of the seven electrode plates 23 provided in the electrolytic cell 10 are illustrated in order to facilitate understanding of the shape and the like of the components of the electrolytic cell 10. In this case, in the electrolytic cell 10 (electrolytic cell main body 10a) of this example, as shown in FIGS. 4 and 5, each electrode plate 23 is accommodated in a state of standing in the electrolytic treatment space S1.

  The connection conductor 24 is a conductor for connecting the two electrode plates 23 arranged on both ends of the seven electrode plates 23 accommodated in the electrolytic treatment space S1 to the power supply unit 13. As shown in FIG. 3, as an example, the electrode plate 23 is formed in a cylindrical shape with a metal material such as titanium and is welded to the electrode plate 23 while being erected at the center of the electrode plate 23.

  As shown in FIGS. 4 and 5, the electrode holder 25 is disposed between a pair of adjacent electrode plates 23 and 23, and the electrode plates 23 and 23 are separated from each other in the electrolytic treatment space S1. It is configured to be held by. Specifically, in the electrode holder 25, a frame-shaped holding portion 41 and a plurality of partition portions 42 are integrally formed of a resin material (for example, vinyl chloride). In this case, in the electrode holder 25 of this example, as shown in FIG. 3, the frame-shaped holding part 41 is formed in a square frame shape in accordance with the shapes of the processing tank side container body 21 a and the electrode plate 23 in the container body 21. ing. In the figure, only two of the six electrode holders 25 provided in the electrolytic cell 10 are shown in order to facilitate understanding of the shape and the like of the components of the electrolytic cell 10. .

  Moreover, in the electrode holder 25 of this example, when the electrode holder 25 is accommodated in the electrolytic treatment space S1 together with each electrode plate 23 as shown in FIGS. A configuration is adopted in which the frame-shaped holding portion 41 is in contact with the outer edge portion and holds both the electrode plates 23 and 23. In this case, the frame-shaped holding portion 41 is provided with a rectangular opening 41a that is slightly smaller than the outer shape of the electrode plate 23, and each partition arranged at equal intervals in the inner space S2 of the opening 41a. The inner space S2 is partitioned by the portion 42 into a plurality of unit spaces S3 adjacent in the width direction of the electrode plate 23 to be held.

  As shown in FIG. 4, in the electrode holder 25 of this example, the dilute hydrochloric acid introduced into the electrolytic treatment space S <b> 1 from the introduction hole 33 from the vicinity of the lid body 22 in the lid body 22 in the treatment tank side container body 21 a. And a plurality of recesses 45 that allow flow of the dilute hydrochloric acid flowing through each recess 45 into the inner space S2 (each unit space S3). It is formed in the lower beam part in the shape holding part 41, respectively. Further, in the electrode holder 25 of the present example, a plurality of recesses 47 into which “electrolysis products” generated in each unit space S3 can enter, and “electrolysis products” that enter the recesses 47 are supplied. A plurality of holes 48 guided to the use holes 31 are respectively formed in the upper beam portion of the frame-shaped holding portion 41.

  In the electrode holder 25 of the present example in which the inner space S2 of the frame-shaped holding portion 41 is partitioned into ten unit spaces S3 by nine partition portions 42, the recesses 45 to 47 and the holes 48 are respectively Ten units are provided corresponding to each unit space S3. Further, as shown in FIG. 7, the container body 21 is provided with the above-described supply holes 31 corresponding to the positions of the holes 48.

  In this case, in the electrolytic cell 10 (electrolytic cell body 10a) of this example, as shown in FIGS. 4 and 5, two of the seven electrode plates 23 (the connecting conductors 24 are connected to each other). One of the two electrode plates 23) is held in the electrolytic treatment space S <b> 1 so as to be sandwiched between one of the six electrode holders 25 and the lid body 22, and the two electrode plates 23. In the electrolytic treatment space S1 so that the other of the six electrode holders 25 is sandwiched between the other one of the six electrode holders 25 and the formation surface of the supply hole 31 in the treatment tank side container body 21a. Is retained.

  Moreover, in the electrolytic cell 10 (electrolytic cell main body 10a) of this example, while the frame-shaped holding | maintenance part 41 of each electrode holder 25 is mutually accommodated in electrolytic treatment space S1, holding two adjacent electrodes Five of the seven electrode plates 23 except for the above two are held in the electrolytic treatment space S1 so that the outer edge portion is sandwiched between the frame-shaped holding portions 41, 41 in the tools 25, 25. ing.

  On the other hand, the metering pump 11 is constituted by a tube pump as an example, and supplies dilute hydrochloric acid from the electrolyzed water tank 2 to the electrolyzer 10 (electrolyzer body 10a) according to the control of the controller 16. As shown in FIG. 1, the check valve 12 is disposed in a connecting pipe that connects the metering pump 11 and the electrolytic cell 10 (introduction hole 33 of the electrolytic cell main body 10 a), so that the metering pump 11 (electrolyzed water) While allowing passage of dilute hydrochloric acid in the direction from the tank 2) toward the electrolytic cell 10, the passage of dilute hydrochloric acid in the direction from the electrolytic cell 10 toward the metering pump 11 is restricted. The power supply unit 13 applies a DC voltage for electrolytic treatment between the electrode plates 23 and 23 via both connection conductors 24 under the control of the controller 16.

  The electromagnetic valve 14 is disposed between the water supply and the electrolytic cell 10 (introduction port 35 of the mixing unit 10 b), and allows / restricts the supply of tap water from the water supply to the electrolytic cell 10 according to the control of the controller 16. The flow rate sensor 15 is disposed between the electromagnetic valve 14 (water supply) and the electrolytic cell 10, and detects the flow rate of tap water that passes through the electromagnetic valve 14 and is supplied to the electrolytic cell 10 (mixing unit 10b). Output a sensor signal.

  The controller 16 comprehensively controls the electrolyzed water generating apparatus 1. Specifically, the controller 16 controls the metering pump 11 to supply dilute hydrochloric acid from the electrolyzed water tank 2 to the electrolyzer 10 (electrolyzer body 10a), and controls the power supply unit 13 to electrolyze the electrolyzer 10 (electrolyte). A DC voltage is applied to each electrode plate 23) of the tank body 10a, and the electromagnetic valve 14 is controlled according to the sensor signal from the flow sensor 15 to supply a specified amount of tap water to the electrolytic cell 10 (mixing unit 10b). Let

  In this electrolyzed water generating apparatus 1, when an operation unit (not shown) is operated to instruct the start of generation of hypochlorous acid water, the controller 16 controls the metering pump 11 to perform electrolysis from the electrolyzed water tank 2 to the electrolyzer. 10 (electrolyzer main body 10a) is supplied with dilute hydrochloric acid, and the power supply unit 13 is controlled to start application of a DC voltage between the electrode plates 23 and 23. At this time, dilute hydrochloric acid supplied by the metering pump 11 is introduced into the electrolytic treatment space S1 of the electrolytic cell 10 (electrolytic cell main body 10a) from the introduction hole 33, and each recess 45 provided in each electrode holder 25 is provided. And is caused to flow across the entire bottom of the electrolytic treatment space S1.

  Further, when dilute hydrochloric acid is further supplied by the metering pump 11, the dilute hydrochloric acid in each recess 45 flows into each unit space S 3 via each recess 46, and the electrodes opposed to each other with the electrode holder 25 interposed therebetween. The plate 23 is in contact with dilute hydrochloric acid. As a result, the diluted hydrochloric acid in contact with the electrode plate 23 is electrolyzed to generate an “electrolysis product” composed of a “mixed fluid” of “gas component” and “liquid component”.

  On the other hand, the “gas component” generated in each unit space S3 is generated in the electrolytic treatment space S1 generated by the increase in pressure in the unit space S3 accompanying the generation of gas and the sequential supply of dilute hydrochloric acid by the metering pump 11 ( As the pressure in each unit space S3 rises, it enters into each hole 48 through each recess 47 in the electrode holder 25, and mixes in the mixing processing space S4 (downstream side) in the mixing unit 10b through each supply hole 31. Supplied to the space S4b).

  In addition, the controller 16 is in parallel with the above-described control for supplying dilute hydrochloric acid to the electrolytic cell 10 (electrolytic cell body 10a) by the metering pump 11 and for applying a DC voltage between the electrode plates 23 and 23 by the power supply unit 13. Then, while monitoring the sensor signal from the flow sensor 15, the electromagnetic valve 14 is controlled to start the supply of tap water to the electrolytic cell 10 (mixing unit 10b). Thereby, a specified amount of tap water is supplied from the introduction port 35 into the mixing processing space S4 (upstream space S4a) of the mixing unit 10b.

  In this case, in the electrolytic cell 10 (mixing unit 10b) of this example, the upstream space S4a on the introduction port 35 side where the tap water is introduced and the downstream side where the “electrolysis product” from the electrolytic cell body 10a is introduced. The space S4b is partitioned by the partition portion 21c, and the upstream space S4a and the downstream space S4b are communicated through a small communication hole 37 provided in the partition portion 21c. Accordingly, when the solenoid valve 14 is opened by the controller 16 and tap water is supplied from the water supply to the mixing unit 10b (introduction port 35), the water pressure of the tap water introduced into the upstream space S4a from the introduction port 35 is increased. The pressure in the upstream space S4a becomes high to some extent, and tap water flows from the upstream space S4a into the downstream space S4b through the communication holes 37.

  At this time, the water pressure of the tap water flowing into the downstream space S4b is sufficiently lower than that of the upstream space S4a due to the pressure loss that occurs when the communication holes 37 pass. For this reason, in the mixing unit 10b of the present example, the tap water that has flowed into the downstream space S4b does not invade the electrolytic cell main body 10a (in the electrolytic treatment space S1) from each supply hole 31, Hypochlorous acid is suitably mixed in the downstream space S4b with the "electrolysis product" supplied through the supply hole 31 and the tap water flowing into the downstream space S4b through the communication hole 37. Water is produced.

  In this case, an “electrolysis product (mixed fluid)” containing a very low concentration of hypochlorous acid water as the “liquid component” and a sufficient amount of chlorine as the “gas component” passes through each supply hole 31. When the chlorine is supplied from the electrolytic cell body 10a, chlorine as a “gas component” is mixed with tap water in the downstream space S4b to generate hypochlorous acid water having a desired concentration. When an “electrolysis product (mixed fluid)” containing high-concentration hypochlorous acid water is supplied from the electrolytic cell main body 10a through the supply holes 31, the hypochlorous acid water is on the downstream side. By mixing and diluting with tap water in the space S4b, hypochlorous acid water having a desired concentration is generated.

  Moreover, in the mixing part 10b of this example, a plurality (four in this example) of communication holes 37 are provided in the partition part 21c that partitions the upstream space S4a and the downstream space S4b. In this case, even when a configuration in which one “communication hole” having an opening area equal to the total opening area of each communication hole 37 is provided in the partition portion 21 c instead of the four communication holes 37, the tap water is not The magnitude of the pressure loss that occurs when passing through the “communication hole” is approximately the same as the magnitude of the pressure loss that occurs when tap water passes through the four communication holes 37. For this reason, even in the configuration in which one “communication hole” is provided in the partition portion 21c instead of the four communication holes 37, the downstream space S4b is lower than the upstream space S4a in the same manner as the mixing portion 10b of this example. It can be pressure.

  However, in the configuration having only one “communication hole” provided in the partition portion 21c, there is only one jet of tap water flowing from the upstream space S4a to the downstream space S4b. The flowing tap water (or hypochlorous acid water in which “electrolysis product” and tap water are mixed) and the tap water newly flowing into the downstream space S4b from the “communication hole” are downstream. There is a risk of being discharged from the discharge port 36 without being suitably stirred in the space S4b.

  On the other hand, in the mixing unit 10b of the present example in which the plurality of communication holes 37 are provided in the partition portion 21c, the tap water in the upstream space S4a is changed to the tap water (or hypochlorous acid water in the downstream space S4b). ) And the tap water (or hypochlorous acid water) in the downstream space S4b is suitably stirred by a plurality of jets of tap water from the communication holes 37. The Thereby, an “electrolysis product” and tap water (or hypochlorous acid water) are suitably mixed. Thereafter, the hypochlorous acid water generated in the downstream space S4b is discharged from the discharge port 36 and stored in the electrolyzed water tank 3.

  Thus, in this mixing part 10b, the inlet 35 for introducing “source water (in this example, tap water)”, the supply hole 31 for introducing “electrolysis product”, and “electrolyzed water (in this example) , (Hypochlorous acid water) ”is provided in the mixing portion side container body 21b provided with the discharge port 36, and the mixing portion side container body 21b (mixing processing space S4) in the upstream side space S4a on the introduction port 35 side and And a partition portion 21c provided with a communication hole 37 that partitions the downstream space S4b on the discharge port 36 side and communicates the spaces S4a and S4b with each other, and a supply hole 31 is supplied from the electrolytic cell body 10a. The “electrolysis product” is opened so that it can be introduced into the downstream space S4b. The electrolyzed water generating apparatus 1 includes the mixing unit 10 and the electrolyzer main body 10a, and is configured to generate “electrolyzed water”.

  Therefore, according to this mixing part 10b and the electrolyzed water generating apparatus 1, the presence of the partition part 21c provided with the communication hole 37 causes the electrolytic cell main body 10a to be more than the upstream space S4a into which tap water is introduced from the introduction port 35. Since the pressure in the downstream space S4b into which the “electrolysis product” from is introduced can be sufficiently reduced, it is preferable to avoid a situation where tap water enters the electrolytic cell body 10a through the supply hole 31. can do. Thereby, according to this mixing part 10b and the electrolyzed water production | generation apparatus 1, since the situation where the diluted hydrochloric acid in the electrolytic cell main body 10a is diluted with a tap water can be avoided, electrolysis efficiency of the diluted hydrochloric acid in the electrolytic cell main body 10a is enough. The amount of power required for electrolysis can be sufficiently reduced. Further, by avoiding the intrusion of tap water from the mixing unit 10b into the electrolytic cell main body 10a, the “electrolysis product” generated in the electrolytic cell main body 10a is efficiently supplied from the electrolytic cell main body 10a to the mixing unit 10b. Therefore, hypochlorous acid water having a desired concentration can be efficiently generated in a short time.

  Moreover, according to this mixing part 10b and the electrolyzed water generating apparatus 1, tap water from each communication hole 37 is formed by forming a plurality of communication holes 37 (four in this example) in the partition part 21c of the mixing part 10b. The tap water and the “electrolysis product” can be suitably agitated in the downstream space S4b by the jets of, so that both can be suitably mixed.

  Moreover, according to this electrolyzed water generating apparatus 1, the "electrolysis tank" and the "mixer" are formed by integrally forming the mixing section side container body 21b in the mixing section 10b and the processing tank side container body 21a in the electrolytic tank main body 10a. The space required for the installation of the “electrolyzer” and “mixer” can be made sufficiently smaller than the configuration in which the “electrolyzer” and the “mixer” are integrated. ”And“ mixer ”are not required to be sealed to seal the joint portion, and thus the manufacturing cost of the electrolyzed water generating apparatus 1 can be sufficiently reduced.

  The configurations of the “mixer” and the “electrolyzed water generating device” are not limited to the configuration examples of the electrolytic cell 10 (mixing unit 10b) and the electrolyzed water generating device 1 described above. For example, the mixing unit 10b having the partition part 21c provided with the four communication holes 37 has been described as an example. However, the number of [communication holes] provided in the “partition part” is not limited thereto, and one or more Any number can be specified. Further, the shape of the “communication hole” is not limited to the round hole such as the communication hole 37, and can be defined as an arbitrary shape such as an elliptical hole, a triangular hole, a rectangular hole, or a polygonal hole. In addition, the configuration in which the electrolytic cell main body 10a corresponding to the “electrolysis cell” and the mixing unit 10b corresponding to the “mixer” are integrally formed has been described as an example. Can be formed separately.
