Description

[Technical field]

[0001] The present invention relates to a slightly acidic electrolyzed water activation treatment device, a slightly acidic electrolyzed water generating system, a slightly acidic electrolyzed water producing method, and a slightly acidic electrolyzed water activation method. [Background technology]

[0002] In order to prevent the spread of infectious diseases such as the new coronavirus, it is important to disinfect objects that have been touched by many people, and alcohol has been widely used for this purpose. However, alcohol has the problem that it can cause rough skin when it comes into contact with human skin, and it is difficult to disperse it in the air because it is highly irritating and flammable.

[0003] On the other hand, hypochlorous acid water can also be used for sterilization apart from alcohol. Among them, the slightly acidic hypochlorous acid water with pH 5.0 to 6.5 has the advantage that it is less likely to cause rough skin, is low-irritant and non-flammable, and is less harmful even if it is diffused into the air by a sprayer or humidifier. In addition, the disinfection and sterilization using the hypochlorous acid water is disclosed on the Ministry of Health, Labor and Welfare website, for example, as described in Non-Patent Document 1 below. [Prior art documents] [Non-patent literature]

[0004] [Non-Patent Document 1] https: / / www.mhlw.go.jp / stf / seisakunitsuite / bunya / syoudoku_00001.html Summary of the Invention [Problem to be solved by the invention]

[0005] Generally, hypochlorous acid water can be produced as electrolyzed water by adding a chlorine-containing electrolyte (such as sodium chloride) to water and performing electrolysis.

[0006] However, there is a problem that the hypochlorous acid in the electrolyzed water decomposes over time, i.e., the expiration date of the electrolyzed water is short.

[0007] In addition, if a large amount of electrolytes is included, the generated hypochlorous acid reacts with the cations (e.g., sodium ions) ionized from the electrolytes, which makes it easier to produce hypochlorites (e.g., sodium hypochlorite). Unlike hypochlorous acid itself, hypochlorites are often highly toxic, and there is also the issue that the amount of electrolytes must be kept as low as possible.

[0008] In response to the above-mentioned problems, for example, Patent No. 6648390 describes a technology that uses dilute hydrochloric acid as the electrolyte to produce electrolyzed water containing hypochlorous acid while suppressing the production of hypochlorite. However, since the amount of electrolyte is small, there are problems in that it is not easy to increase the concentration of hypochlorous acid or adjust the pH of the hypochlorous acid water.

[0009] In view of the above problems, the present invention aims to provide a slightly acidic electrolyzed water activation treatment device and a slightly acidic electrolyzed water generation system, a slightly acidic electrolyzed water production method, and a slightly acidic electrolyzed water activation method that easily enable higher hypochlorous acid concentration and pH adjustment. [Means for solving the problem]

[0010] The present inventors have conducted intensive research into the above-mentioned problems, and have discovered that by stirring the generated slightly acidic electrolyzed water while electrolyzing it, it is possible to easily achieve a higher hypochlorous acid concentration and adjust the pH. This has led to the completion of the present invention.

[0011] That is, a slightly acidic electrolyzed water generating system according to one aspect of the present invention includes a storage tank for storing slightly acidic electrolyzed water, and a slightly acidic electrolyzed water activation treatment device for performing an activation treatment on the slightly acidic electrolyzed water stored in the storage tank.

[0012] In addition, in this respect, although not limited thereto, it is preferable that a slightly acidic electrolyzed water generator is provided, and the storage tank is configured to store the slightly acidic electrolyzed water generated by the slightly acidic electrolyzed water generator.

[0013] In addition, in this respect, although not limited thereto, it is preferable to provide a return pipe for returning the slightly acidic electrolyzed water activated by the slightly acidic electrolyzed water activation treatment device to the storage tank.

[0014] In addition, in this respect, although not limited thereto, it is preferable that the slightly acidic electrolyzed water generating device generates the slightly acidic electrolyzed water by adding dilute hydrochloric acid to tap water.

[0015] In addition, in this respect, it is preferable, but not limited to, to have a first detection means that is installed in the storage tank and detects at least one of the chlorine concentration and pH of the slightly acidic electrolyzed water in the storage tank, and a water supply means that supplies the water to the slightly acidic electrolyzed water activation treatment device when the chlorine concentration and pH values ​​detected by the detection means are outside of a predetermined range.

[0016] Moreover, the device for activating slightly acidic electrolyzed water according to another aspect of the present invention preferably includes a pair of electrodes for electrolyzing the slightly acidic electrolyzed water, and a stirring member for stirring the slightly acidic electrolyzed water.

[0017] A method for producing slightly acidic electrolyzed water according to another aspect of the present invention includes the steps of generating slightly acidic electrolyzed water, storing the slightly acidic electrolyzed water, and further electrolyzing the slightly acidic electrolyzed water.

[0018] A method for activating slightly acidic electrolyzed water according to another aspect of the present invention includes the steps of generating slightly acidic electrolyzed water, storing the slightly acidic electrolyzed water, and further electrolyzing the slightly acidic electrolyzed water. Effect of the Invention

[0019] As described above, the present invention provides a slightly acidic electrolyzed water activation treatment device, a slightly acidic electrolyzed water generation system, a slightly acidic electrolyzed water production method, and a slightly acidic electrolyzed water activation method that easily enable higher hypochlorous acid concentration and pH adjustment. [Brief description of the drawings]

[0020] [Figure 1] FIG. 1 is a diagram showing an outline of a system for generating slightly acidic electrolyzed water according to an embodiment. [Diagram 2] 2A to 2C are diagrams showing a pair of electrodes and a support structure thereof according to an embodiment of the present invention. BEST MODE FOR CARRYING OUT THEINVENTION

[0021] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention can be embodied in many different forms, and the specific examples described in the following embodiments and examples can be appropriately modified and adjusted, and the present invention is not limited thereto.

[0022] FIG. 1 is a schematic diagram of a slightly acidic electrolyzed water generating system S according to this embodiment (hereinafter referred to as "this system").

[0023] As shown in the figure, the system S includes a slightly acidic electrolyzed water generator 1, a storage tank 2 for storing the slightly acidic electrolyzed water W generated by the slightly acidic electrolyzed water generator 1, and a slightly acidic electrolyzed water activation treatment device 3 for performing an activation treatment on the slightly acidic electrolyzed water W stored in the storage tank 2. Other configurations will become clear from the description below.

[0024] The effect of the present system S will become clear from the description below, but by storing the slightly acidic electrolyzed water W generated by the slightly acidic electrolyzed water generating device 1 and then passing it through the slightly acidic electrolyzed water activation treatment device 3, the concentration of hypochlorous acid can be increased and the pH can be kept within the slightly acidic range. Previously, slightly acidic electrolyzed water was simply stored as it was once generated, but with the present system S, the concentration and pH, which change during storage, are reactivated, making it possible to store and ship the water in a higher quality state.

[0025] First, the system S includes a slightly acidic electrolyzed water generating device 1. The slightly acidic electrolyzed water generating device 1 is not limited as long as it can generate the slightly acidic electrolyzed water W, but is preferably a device that can generate slightly acidic electrolyzed water by electrolysis without adding alkali metals and alkaline earth metals as electrolytes to water. By not adding alkali metals as electrolytes, when hypochlorous acid is generated by electrolysis, the amount of the salt that reacts with the alkali metal can be reduced as much as possible. Note that "not added" here means that an unavoidable content in the water used as a raw material is allowed, for example, 200 mg or less per liter of general tap water, more preferably 100 mg or less, and even more preferably 50 mg or less. On the other hand, it is preferable that the electrolyte to be added is dilute hydrochloric acid. By using dilute hydrochloric acid, there is an advantage that it is possible to include chlorine, which is a raw material for hypochlorous acid, without adding alkali metals.

[0026] In addition, in the system S, the water used as the raw material may be pure water, but tap water may also be used. Tap water already contains a small amount of electrolyte, which functions as an electrolyte that promotes electrolysis. When tap water is used, it is preferable to install a first filter F to remove excess metal ions and solids contained in the tap water.

[0027] As is clear from the above description, "slightly acidic electrolyzed water" refers to water that has been made slightly acidic by adding electrolytes to water and electrolyzing it, and more specifically, refers to electrolyzed water that is slightly acidic due to the inclusion of hypochlorous acid generated by electrolysis. "Slightly acidic" refers to an acidic state that is closer to neutral than general weak acidity, specifically a state between pH 5 and 6.5. In other words, slightly acidic electrolyzed water refers to electrolyzed water that contains hypochlorous acid generated by electrolysis and has a pH between 5 and 6.5. In addition, the chlorine concentration of the slightly acidic electrolyzed water W generated by the present system S is preferably 35 ppm or more, although it is not limited thereto. By making it 35 ppm or more, the effect of the slightly acidic electrolyzed water can be effectively obtained.

[0028] As described above, the system S is provided with a storage tank 2 for storing the slightly acidic electrolyzed water W generated by the slightly acidic electrolyzed water generating device 1. By providing the storage tank 2, the generated slightly acidic electrolyzed water W can be stored and, as necessary, divided into containers for shipping. As will be apparent from the description below, the storage tank 2 also serves as a supply source of slightly acidic electrolyzed water for the slightly acidic electrolyzed water activation treatment device 3 in the subsequent stage.

[0029] In this system S, the slightly acidic electrolyzed water generating device 1 and the storage tank 2 are connected by a storage pipe 11, and the slightly acidic electrolyzed water W generated by the slightly acidic electrolyzed water generating device 1 is transported to the storage tank 2 by this storage pipe 11.

[0030] In the present system S, the slightly acidic electrolyzed water W generated by the slightly acidic electrolyzed water generator 1 may be transported directly to the storage tank 2 via the storage pipe 11, or a filtration tank may be provided along the way to temporarily store the water. By passing the water through the filtration tank, it becomes possible to remove by precipitation or filtration trace amounts of solid matter that are present in the raw water and that cannot be completely removed by the first filter F. When a filtration tank is provided, it is preferable to provide a water supply means such as a water supply pump in the filtration tank to supply water to the storage tank 2.

[0031] In addition, the present system S is preferably provided with a detection means 21 that is installed in the storage tank 2 and is capable of detecting at least one of, and preferably both of, the chlorine concentration and pH of the slightly acidic electrolyzed water W in the storage tank 2. This makes it possible to detect the status of the slightly acidic electrolyzed water W in real time. The detection means for detecting pH is preferably, for example, a pH meter, and for chlorine concentration, a chlorine concentration meter. The installation location of the detection means 21 is not limited as long as it allows confirmation of the status of the slightly acidic electrolyzed water W in the storage tank 2, and it may be installed not in the storage tank 2 but in the activation pipe 23 or filling pipe 41 located behind it. Furthermore, the present system S may be provided with a detection means 21 that is capable of detecting the chlorine concentration and / or ... As shown in FIG. 1, the control device 5 may be provided in the upstream of the filling device 4.

[0032] In addition, in the present system S, it is preferable to provide a water level detection means 22 for measuring the water level in the storage tank 2. When the water level detected by the water level detection means 22 is sufficient, the weak acidic electrolyzed water W is not generated any more, whereas when the water level drops, an instruction is issued to the weak acidic electrolyzed water generator 1 to generate the weak acidic electrolyzed water W and supply it to the storage tank 2, thereby making it possible to control the system.

[0033] In addition, the system S preferably includes a water supply means 24 for supplying the slightly acidic electrolyzed water W to the slightly acidic electrolyzed water activation treatment device 3 when at least one of the chlorine concentration and pH values ​​detected by the detection means 21 is outside a predetermined range. This allows the chlorine concentration and pH of the slightly acidic electrolyzed water W in the storage tank 2 to be kept at a desired value, while when the chlorine concentration and pH value are outside the desired value, the slightly acidic electrolyzed water W in the storage tank 2 is supplied to the slightly acidic electrolyzed water activation treatment device 3 described below, activated, and the value of the slightly acidic electrolyzed water W in the storage tank 2 can be adjusted to a desired range. The water supply means 24 is not limited as long as it can supply the slightly acidic electrolyzed water W to the slightly acidic electrolyzed water activation treatment device 3, and for example, a water supply pump or the like can be used.

[0034] In the present system S, the storage tank 2 and the slightly acidic electrolyzed water activation treatment device 3 are connected by an activation pipe 23, and the slightly acidic electrolyzed water W stored in the storage tank 2 is transported to the slightly acidic electrolyzed water activation treatment device 3 by this activation pipe 23. The activation pipe 23 may be branched midway and connected to the charging device 4 and the control device 5 provided in the preceding stage. In this way, the activation treatment pipe and the charging pipe can be shared to achieve a compact configuration.

[0035] In the present system S, it is also preferable to provide a second filter F in the activation pipe 23. By providing the second filter F, it becomes possible to remove excess metal ions, solid matter, and the like remaining in the storage tank 2.

[0036] The slightly acidic electrolyzed water activation treatment device 3 in the system S performs activation treatment on the stored slightly acidic electrolyzed water W. Here, "activation treatment" refers to a treatment to increase the chlorine concentration in the slightly acidic electrolyzed water W and a treatment to keep the pH within a desired range. As is clear from this description, the "activation treatment" is a treatment to activate the already generated slightly acidic electrolyzed water W, and is different from a treatment to generate the slightly acidic electrolyzed water W. In that sense, the presence of the storage tank 2 is essential.

[0037] The slightly acidic electrolyzed water activation treatment device 3 of the present system S preferably includes a pair of electrodes 31 for electrolyzing the slightly acidic electrolyzed water W, and a stirring member 32 for stirring the slightly acidic electrolyzed water W. The slightly acidic electrolyzed water activation treatment device 3 naturally includes a storage tank 33 for storing the slightly acidic electrolyzed water W, and can store the slightly acidic electrolyzed water W whose chlorine concentration and pH are outside the desired range. It is preferable to provide the stirring member 32 in order to quickly bring the pH into the desired range, but in cases where it is acceptable to take a relatively long time, it is possible to omit the stirring member 32 and only use the pair of electrodes 31.

[0038] The pair of electrodes 31 of the weakly acidic electrolyzed water activation treatment device 3 of the present system S are members that further electrolyze the weakly acidic electrolyzed water W. The electrode material of the pair of electrodes 31 can be appropriately adjusted and is not limited, but examples include precious metals such as platinum that are not corroded by chlorine. The present system S can return the pH biased to the strongly acidic side to the slightly acidic side by electrolysis using the pair of electrodes 31 in the weakly acidic electrolyzed water activation treatment device 3. More specifically, hypochlorous acid in the weakly acidic electrolyzed water W is decomposed over time to produce hydrochloric acid, but the pH and chlorine concentration can be adjusted by electrolysis using the pair of electrodes 31 to produce the weakly acidic electrolyzed water W again. In addition, in the present system S, when producing the weakly acidic electrolyzed water W using hydrochloric acid as an electrolyte without adding an electrolyte such as an alkali metal, there may be a limit to the chlorine concentration produced because no alkali metal is added, but by performing electrolysis and stirring after production as in the present system S, it is even possible to include a chlorine concentration higher than the chlorine concentration at the stage of production by the weakly acidic electrolyzed water production device 1. In particular, since the device for generating slightly acidic electrolyzed water W without adding alkali metals is designed to use untreated tap water as the raw material, it is currently extremely difficult and unthinkable to recharge the slightly acidic electrolyzed water W once stored in the device 1. Therefore, the deteriorated slightly acidic electrolyzed water W cannot be regenerated and must be discarded. However, by introducing the device 3 for activating the slightly acidic electrolyzed water W in the system S, it becomes possible to regenerate the slightly acidic electrolyzed water W and further increase the chlorine concentration.

[0039] In addition, although not limited thereto, the pair of electrodes 31 of the weakly acidic electrolyzed water activation treatment device 3 of the present system S is preferably structured to be sufficiently resistant to corrosion caused by chlorine and the like, since it is disposed in the weakly acidic electrolyzed water W. FIG. 2 shows the pair of electrodes 31 and its support structure in the present system S. As shown in this figure, the pair of electrodes 31 includes a pair of electrodes 31 and a support structure 311 that supports the pair of electrodes 31. The support structure 311 is also configured to include a pair of support plates 3111 that have holes formed therein and are disposed on the outer sides of the pair of electrodes 31, and side plates 3112 for ensuring the distance between the support plates 3111. In addition, in order to make the support plates 3111 and the side plates 3112 sufficiently resistant to corrosion caused by chlorine and the like as described above, resin screws that are resistant to corrosion are used, and the pair of support plates 3111 and the side plates 3112 are formed with connecting holes and protrusions that are combined, and are assembled so that they fit together. By adopting this new structure in System S, it is possible to stably support the electrodes while preventing corrosion, making it possible to more than double the electrode capacity.

[0040] In addition, the pair of electrodes 31 is preferably connected to an external power supply 34. By connecting to the external power supply 34, a voltage can be applied between the pair of electrodes 31, and electrolysis can be performed again. In this case, the electric field generated between the pair of electrodes 31 is not limited as long as it can activate the slightly acidic electrolyzed water W, but is preferably in the range of 12V / 0.6A to 12V / 1.8A, and more preferably in the range of 12V / 0.7A to 12V / 1.5A.

[0041] In the slightly acidic electrolyzed water activation treatment device 3, the stirrer 32 stirs the slightly acidic electrolyzed water W in the electrolysis process. Stirring causes electrolysis by the pair of electrodes 31, making it possible to uniformly disperse hypochlorous acid in the slightly acidic electrolyzed water W, improving efficiency. The structure of the stirrer 32 is not limited as long as it is capable of stirring, but it is preferable that the stirrer 32 has a shaft member 321, a power member 322 that rotates the shaft member 321, and a blade member 323 attached to the tip of the shaft member 321.

[0042] In addition, the present system S is preferably provided with a return pipe 35 for returning the slightly acidic electrolyzed water W activated by the slightly acidic electrolyzed water activation treatment device 3 to the storage tank. This allows the slightly acidic electrolyzed water W to be stored again in the storage tank 2. In particular, by returning the slightly acidic electrolyzed water W that has been activated this time, the slightly acidic electrolyzed water W can be made to fall within a desired range. As is clear from the above description, in the present system S, a loop is formed by the storage tank 2, the activation pipe 23, the slightly acidic electrolyzed water activation treatment device 3, and the return pipe 35.

[0043] In the present system S, it is also preferable to provide a third filter F in the return pipe 35. By providing the third filter F, it becomes possible to remove excess metal ions and solid matter remaining in the slightly acidic electrolyzed water activation treatment device 3.

[0044] The system S also includes a filling pipe 41 and a filling device 4 connected to the storage tank 2, and can fill the necessary amount of slightly acidic electrolyzed water W from the storage tank 2 into the subdivision containers C. In this case, the filling pipe 41 may be partially shared with the return pipe 35 and the activation pipe 23. By sharing the pipes, the number of pipes can be reduced, and the installation space of the system S can be saved.

[0045] In addition, in this system S, a control device 5 is provided in front of the filling device 4. The control device 5 is connected to a detection means 21 to monitor the pH and chlorine concentration, and is also connected to a water level detection means 22 to detect the water level in the storage tank 2, thereby driving the slightly acidic electrolyzed water generator 1 as necessary to generate the slightly acidic electrolyzed water W, and driving the slightly acidic electrolyzed water activation treatment device 3 as necessary to control the pH and chlorine concentration.

[0046] (Slightly acidic electrolyzed water production method / slightly acidic electrolyzed water activation method) Here, a method for producing slightly acidic electrolyzed water (hereinafter referred to as "the present production method") and a method for activating slightly acidic electrolyzed water (hereinafter referred to as "the present activation method") using the above-mentioned present system S will be described.

[0047] As is clear from the above description, the present production method comprises the steps of (S1) generating slightly acidic electrolyzed water, (S2) storing the slightly acidic electrolyzed water, and (S3) further electrolyzing the slightly acidic electrolyzed water.

[0048] In this production method, as described above, the slightly acidic electrolyzed water is produced, temporarily stored, and then the stored slightly acidic electrolyzed water is further stirred and electrolyzed to activate it and complete the slightly acidic electrolyzed water. However, from the viewpoint of activating the slightly acidic electrolyzed water that has already been produced, this activation method is the same as the present method.

[0049] First, the method includes the step of (S1) producing slightly acidic electrolyzed water. The slightly acidic electrolyzed water is produced by the slightly acidic electrolyzed water device as described above.

[0050] This production method also includes a step (S2) of storing the slightly acidic electrolyzed water, in which the slightly acidic electrolyzed water is sent to the storage tank 2 via a storage pipe and stored therein.

[0051] The method also includes a step (S3) of further electrolyzing the slightly acidic electrolyzed water. This step is performed by the above-mentioned slightly acidic electrolyzed water activation treatment device, and is very useful in that it can bring the chlorine concentration and pH of the slightly acidic electrolyzed water stored in the storage tank within a predetermined range when they are outside the predetermined range. In this case, it is preferable to perform a stirring process in parallel. By performing electrolysis and stirring together, a more efficient activation process is possible. It is preferable to provide a stirring member in order to quickly bring the pH into a desired range, but in cases where it is acceptable to take a relatively long time, it is possible to omit the stirring member and only use a pair of electrodes.

[0052] In addition, the present manufacturing method preferably includes a step of filling the slightly acidic electrolyzed water W into small containers C for sale. This makes it possible to take the slightly acidic electrolyzed water W in the storage tank 2 to the outside.

[0053] As described above, the present embodiment provides a slightly acidic electrolyzed water activation treatment device, a slightly acidic electrolyzed water generation system, a slightly acidic electrolyzed water production method, and a slightly acidic electrolyzed water activation method that can easily adjust the concentration of hypochlorous acid and pH.

[0054] Here, the system for generating slightly acidic electrolyzed water according to the above embodiment was actually manufactured, and its effects were confirmed. The following will explain the results.

[0055] First, a slightly acidic electrolyzed water generating device (Hokuetsu AP-600W) was installed and connected to a storage pipe so that the slightly acidic electrolyzed water could be stored in a storage tank (polyethylene, 2000 L).

[0056] Furthermore, one end of the activation pipe was connected to the storage tank, and the other end was connected to an activation tank (made of polyethylene, 2000 L). An electrolysis device equipped with a pair of electrodes and a stirring device were installed in the activation tank. This constituted a slightly acidic electrolyzed water activation treatment device. A return pipe was connected between the activation tank and the storage tank.

[0057] A filling pipe was further connected to the activation tank, and a control device and a filling device were connected so that the slightly acidic electrolyzed water could be discharged outside the system.

[0058] After constructing the above system, tap water was actually put into the slightly acidic electrolyzed water generator to generate slightly acidic electrolyzed water. As a result, 1500 L of slightly acidic electrolyzed water was obtained. The chlorine concentration at the time of generation of the slightly acidic electrolyzed water was 39 ppm, and the pH was 5.5.

[0059] The resulting slightly acidic electrolyzed water was left to stand for 90 days, after which the pH of the slightly acidic electrolyzed water was 4.8, and the chlorine concentration had dropped to 35 ppm.

[0060] Therefore, the above-mentioned slightly acidic electrolyzed water was put into a slightly acidic electrolyzed water activation device and activated. As a result, bubbles were generated by electrolysis, and activation was performed by stirring the bubbles with a stirrer, and it was confirmed that the chlorine concentration was increased to 55 ppm and the pH was again within the desired range of 6.5. In particular, it was confirmed that this example can produce slightly acidic electrolyzed water with a chlorine concentration higher than the capacity of the slightly acidic electrolyzed water generating device.

[0061] As described above, the effects of the present invention were confirmed by this embodiment. [Industrial Applicability]
