しかしながら、上記従来例による場合、分岐装置及び混合装置を有した構成になっていることから、装置全体の構成が複雑となり、低コスト化を図ることが困難という問題が指摘されている。また、PH7〜8前後の殺菌性電解水については、殺菌効果の持続時間が短いという別の問題も指摘されている。   However, in the case of the above conventional example, since the configuration includes a branching device and a mixing device, the configuration of the entire device is complicated, and it is difficult to reduce the cost. Moreover, another problem that the duration of the bactericidal effect is short is pointed out about bactericidal electrolyzed water having a pH of around 7 to 8.

本発明は上記事情に鑑みて創作されたものであって、その目的とするところは、生成装置の構成が複雑とならず、殺菌性電解水の殺菌効果の持続時間についても長い殺菌性電解水生成方法及びこれを用いた生成装置を提供することにある。   The present invention was created in view of the above circumstances, and the object of the present invention is that the structure of the generating device is not complicated and the bactericidal electrolyzed water has a long sterilizing effect duration. An object is to provide a generation method and a generation apparatus using the same.

本発明に係る殺菌性電解水生成方法は、塩化ナトリウム水溶液に対し、NaとClOの電位の高いイオンが得られる程度の電解電流により電気分解を行い、これにより前記イオンが含まれた殺菌性電解水を生成した内容になっている。 The method for producing bactericidal electrolyzed water according to the present invention comprises electrolyzing a sodium chloride aqueous solution with an electrolysis current to the extent that ions with high potentials of Na + and ClO are obtained, and thereby sterilizing containing the ions. It is the contents that generated the electrolyzed water.

上記した殺菌性電解水生成方法による場合、殺菌性電解水について加水分解が行われ、電解水に含まれる少なくともNaClOがクラスター化されることから、殺菌性電解水の殺菌効果が高いだけでなくその持続時間が長くなる。しかも塩化ナトリウム水溶液を用い、その電解電流の大きさを従来に比べて大きくするだけの改良で良いことから、この点で低コスト化を図ることが容易になる。   In the case of the above bactericidal electrolyzed water generation method, the bactericidal electrolyzed water is hydrolyzed, and at least NaClO contained in the electrolyzed water is clustered. Longer duration. In addition, since it is only necessary to use an aqueous sodium chloride solution and make the electrolysis current larger than the conventional one, the cost can be easily reduced in this respect.

本発明に係る殺菌性電解水生成装置は、前記電解電流を生成する電源装置と、前記電源装置の出力側に接続されており且つ前記塩化ナトリウム水溶液を溜める電解槽に入れられる電極ユニットとを備えている。   The bactericidal electrolyzed water generating device according to the present invention includes a power supply device that generates the electrolysis current, and an electrode unit that is connected to an output side of the power supply device and is placed in an electrolytic cell that stores the sodium chloride aqueous solution. ing.

上記した殺菌性電解水生成装置による場合、上記殺菌性電解水生成方法が用いられた構成になっていることから、殺菌効果が高く且つその持続時間が長い殺菌性電解水を生成することが可能になる。また、全体構成が単純であることから、装置自体の低コスト化を容易に図ることが可能になる。   When the above bactericidal electrolyzed water generating device is used, the bactericidal electrolyzed water generating method is used, so that it is possible to generate bactericidal electrolyzed water having a high bactericidal effect and a long duration. become. Further, since the overall configuration is simple, it is possible to easily reduce the cost of the device itself.

上記した殺菌性電解水生成装置については、電極ユニットの電解用電極がチタンから構成されていることか好ましい。   About the above-mentioned bactericidal electrolyzed water generating apparatus, it is preferable that the electrode for electrolysis of an electrode unit is comprised from titanium.

上記した形態の殺菌性電解水生成装置による場合、殺菌性電解水の濃度等に応じて電解電流のレベルを大きく設定したとしても電極劣化が生じ難く、この点で故障の発生が抑制される。   In the case of the bactericidal electrolyzed water generating device having the above-described form, electrode deterioration hardly occurs even if the level of the electrolysis current is set large according to the concentration of the bactericidal electrolyzed water, and the occurrence of failure is suppressed in this respect.

本発明の実施形態を説明するための図であって殺菌性電解水生成装置の概略構成図である。It is a figure for demonstrating embodiment of this invention, Comprising: It is a schematic block diagram of a bactericidal electrolyzed water generating apparatus. 同生成装置による殺菌性電解水生成中の電源装置から出力される電圧V、電解電流I等の時間的変化を示すグラフである。It is a graph which shows temporal changes, such as the voltage V output from the power supply device during the bactericidal electrolyzed water production | generation by the production | generation apparatus, and electrolysis current I. 同生成装置により生成された殺菌性電解水に含まれるNaClOがクラスター化される様子を示した模式図である。It is the schematic diagram which showed a mode that NaClO contained in the bactericidal electrolyzed water produced | generated by the production | generation apparatus was clustered.

以下、本発明の実施形態を図1乃至図3を参照して説明する。ここに例として挙げる殺菌性電解水生成装置1(以下単に「生成装置」と称することにする)は、本発明の殺菌性電解水生成方法を用いて無隔膜の電解槽2に入れられた塩化ナトリウム水溶液SAを電気分解して殺菌性電解水EWを生成する装置であって、電圧V及び電解電流Iを生成する電源装置10と、電源装置10の出力側に接続されており且つ塩化ナトリウム水溶液SAを溜める電解槽2内に入れられる電極ユニット20とを備えている。以下、生成装置1の各部の詳細を説明する。   Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3. The bactericidal electrolyzed water generating device 1 (hereinafter simply referred to as “generating device”), which is exemplified here, is chlorinated in an electrolyzer 2 of a non-diaphragm using the bactericidal electrolyzed water generating method of the present invention. A device for electrolyzing a sodium aqueous solution SA to produce bactericidal electrolyzed water EW, which is connected to the power supply device 10 for generating voltage V and electrolysis current I, and to the output side of the power supply device 10, and is a sodium chloride aqueous solution And an electrode unit 20 placed in the electrolytic cell 2 for storing SA. Hereinafter, the detail of each part of the production | generation apparatus 1 is demonstrated.

電源装置10は、商用交流を入力として所定の直流の電源電圧をする電源部11と、電源電圧を入力として直流の電圧Vを可変可能に生成する電圧変換部12と、電圧Vのレベルを検出する電圧検出部13と、電圧変換部12から出力された電解電流Iのレベルを検出する電流検出部14と、殺菌性電解水EWの濃度に対応した作動時間Tのデータ等を設定入力するとともにその設定時間等を表示出力するための入出力部16と、電源電圧が供給されたマイコンであって殺菌性電解水EWの生成中、電圧V及び電解電流Iの検出結果に基づいて電極ユニット20に供給する電力P(=V×I)を常時監視するとともに、電力Pを常に一定に保つのに必要な電圧Vが生成されるように電圧変換部12を制御する制御部15とを備えている。   The power supply device 10 detects a level of the voltage V, a power supply unit 11 that receives a commercial AC as an input and generates a predetermined DC power supply voltage, a voltage converter 12 that variably generates a DC voltage V as an input from the power supply voltage, and And setting and inputting the data of the operating time T corresponding to the concentration of the bactericidal electrolyzed water EW, etc. An input / output unit 16 for displaying the set time and the like, and a microcomputer to which a power supply voltage is supplied. During generation of the bactericidal electrolyzed water EW, the electrode unit 20 is based on the detection result of the voltage V and the electrolysis current I. And a control unit 15 that controls the voltage conversion unit 12 so as to generate a voltage V necessary to keep the power P constant at all times. Yes.

電圧変換部12から電圧V及び電解電流Iが出力される時間は、入出力部16を通じて入力された作動時間Tとされている。殺菌性電解水EWの濃度は、塩化ナトリウム水溶液SAを作成する際の塩の量と作動時間Tにより決定される。制御部15により電力Pを監視しているのは電力効率化及び過電流防止のためである。電解電流Iの制御を電圧Vの調節により行っているのは主として回路の簡単化のためである。   The time during which the voltage V and the electrolysis current I are output from the voltage converter 12 is the operating time T input through the input / output unit 16. The concentration of the bactericidal electrolyzed water EW is determined by the amount of salt and the operating time T when the sodium chloride aqueous solution SA is prepared. The reason why the power P is monitored by the control unit 15 is to improve power efficiency and prevent overcurrent. The control of the electrolysis current I is performed by adjusting the voltage V mainly for simplification of the circuit.

ここでは電圧Vのレベルは13V、電解電流Iのレベルは15〜30Aに各々設定されている。従来装置では、電解電流Iのレベルが5A程度であったものが、本案発明は従来では考えられない程度に電解電流Iのレベルを大きくした点が最も大きな特徴になっている。その結果、生成される殺菌性電解水EWの成分が下記の通り大きく変化するに至った。  Here, the level of the voltage V is set to 13 V, and the level of the electrolysis current I is set to 15 to 30 A. In the conventional apparatus, the level of the electrolysis current I is about 5 A, but the present invention is characterized in that the level of the electrolysis current I is increased to an extent that cannot be considered in the past. As a result, the components of the generated bactericidal electrolyzed water EW changed greatly as follows.

なお、電解電流Iのレベルが大きいことから、電解槽2内の塩化ナトリウム水溶液SAの抵抗値がその温度と共に大きく変化するときは、電力効率が低くなる場合がある。これを回避するためには、図1に破線で示されているように、温度センサー17により塩化ナトリウム水溶液SAの温度を計測し、制御部15により電圧変換部12から出力される電解電流Iを温度センサー17の計測結果に応じて補正すると良い。また、殺菌性電解水EWの濃度を正確に管理する必要があるときには、電解電流Iの大きさから同電解水EWの濃度を検出し(ポーラログラフ法)、その検出結果を入出力部16に表示出力すると良い。  In addition, since the level of the electrolysis current I is large, when the resistance value of the sodium chloride aqueous solution SA in the electrolytic cell 2 changes greatly with the temperature, the power efficiency may be lowered. In order to avoid this, as shown by the broken line in FIG. 1, the temperature of the sodium chloride aqueous solution SA is measured by the temperature sensor 17, and the electrolytic current I output from the voltage converter 12 by the controller 15 is determined. Correction may be made according to the measurement result of the temperature sensor 17. When it is necessary to accurately control the concentration of the bactericidal electrolyzed water EW, the concentration of the electrolyzed water EW is detected from the magnitude of the electrolysis current I (polarographic method), and the detection result is displayed on the input / output unit 16. Output is good.

電極ユニット20は、電源装置10の出力端子に電線を介して電気接続されたカソード電極板21K及びアノード電極板21A(電解用電極に相当)と、電解槽2内に上記電極板を保持するための電極保持部22とを有した構成になっている。  The electrode unit 20 holds a cathode electrode plate 21K and an anode electrode plate 21A (corresponding to an electrode for electrolysis) electrically connected to an output terminal of the power supply device 10 via an electric wire, and the electrode plate in the electrolytic cell 2. The electrode holding part 22 is provided.

カソード電極板21K及びアノード電極板21Aについては、電解電流Iのレベルが大きいことから、その電極劣化を抑制するために、カソード電極板21がチタン、アノード電極板21Aがステンレスから構成されている。  The cathode electrode plate 21K and the anode electrode plate 21A have a high level of electrolysis current I. Therefore, in order to suppress electrode deterioration, the cathode electrode plate 21 is made of titanium and the anode electrode plate 21A is made of stainless steel.

電極保持部22については、カソード電極板21K及びアノード電極板21Aが間隔を開けて対向状態で下向きに取り付けられた本体部221と、本体部221の下側に設けられており且つ外面に水溶液導入孔2221が多数形成された電極カバー部222と、電解槽2の開口縁に引っ掛けて保持するための本体部221の上側に設けられたフック部223とを有し、化学的耐久性及び電気的絶縁性を有したプラスチック等の樹脂から構成されている。  The electrode holding part 22 is provided with a cathode electrode plate 21K and an anode electrode plate 21A facing downward with a gap therebetween, and a main body part 221 which is provided on the lower side of the main body part 221, and an aqueous solution is introduced to the outer surface. It has an electrode cover part 222 in which a large number of holes 2221 are formed, and a hook part 223 provided on the upper side of the main body part 221 for hooking and holding the opening edge of the electrolytic cell 2. It is made of a resin such as an insulating plastic.

上記のように構成された生成装置1の使用方法について説明する。まず、所定量の水に対して塩を混ぜて作られた塩化ナトリウム水溶液SAを電解槽2に入れるとともに電極ユニット20を電解槽2にセットする。そして、電源装置10の入出力部16aを通じて作動時間Tを設定入力する。  The usage method of the production | generation apparatus 1 comprised as mentioned above is demonstrated. First, a sodium chloride aqueous solution SA made by mixing a salt with a predetermined amount of water is placed in the electrolytic cell 2 and the electrode unit 20 is set in the electrolytic cell 2. Then, the operating time T is set and inputted through the input / output unit 16a of the power supply device 10.

この状態で電源装置10のメインスイッチをオンにすると、電源装置10から電圧V及び電解電流Iが出力され、カソード電極板21K及びアノード電極板21Aに供給される。これが設定入力された作動時間Tだけ続けられる。化の過程でカソード電極板21K及びアノード電極板21Aに供給された電解電流Iにより、電解槽2に溜められた塩化ナトリウム水溶液SAが殺菌性電解水EWに変化する。このように生成される殺菌性電解水EWの濃度は、塩化ナトリウム水溶液SAの濃度及び作動時間Tの設定入力を通じて調整可能になっている。殺菌性電解水EWの使用用途に応じた適正な濃度にすれば良い。  When the main switch of the power supply device 10 is turned on in this state, the voltage V and the electrolysis current I are output from the power supply device 10 and supplied to the cathode electrode plate 21K and the anode electrode plate 21A. This is continued for the set operation time T. The sodium chloride aqueous solution SA stored in the electrolytic cell 2 is changed to bactericidal electrolyzed water EW by the electrolysis current I supplied to the cathode electrode plate 21K and the anode electrode plate 21A in the process of conversion. The concentration of the bactericidal electrolyzed water EW thus generated can be adjusted through setting input of the concentration of the sodium chloride aqueous solution SA and the operation time T. What is necessary is just to make it the appropriate density | concentration according to the use application of bactericidal electrolyzed water EW.

生成装置1を用いて、例えば、水10リットルに塩150gが入れられた塩化ナトリウム水溶液SAについて電圧V=13V、電解電流I=18Aの条件で電気分解を行うと、殺菌性電解水EWの濃度は600PPMとなる。また、水10リットルに塩100gが入れられた塩化ナトリウム水溶液SAについて電圧V=13V、電解電流I=16Aの条件で電気分解を行うと、殺菌性電解水EWの濃度は400PPMとなる。  For example, when the sodium chloride aqueous solution SA in which 150 g of salt is placed in 10 liters of water is electrolyzed using the generator 1 under the conditions of a voltage V = 13 V and an electrolysis current I = 18 A, the concentration of bactericidal electrolyzed water EW Is 600 PPM. Moreover, when the sodium chloride aqueous solution SA in which 100 g of salt is put in 10 liters of water is electrolyzed under the conditions of the voltage V = 13 V and the electrolysis current I = 16 A, the concentration of the bactericidal electrolyzed water EW becomes 400 PPM.

上記した生成装置1に使用される殺菌性電解水生成方法は、塩化ナトリウム水溶液SAに対し、高い電位状態のNaとClOの各イオンが得られる程度の電解電流Iにより電気分解を行い、これによりNaClOが含まれた殺菌性電解水EWを生成した内容になっている。上記電気分解に伴う化学反応式については下記の通りである。

Figure 2019030857
Figure 2019030857
The method for producing bactericidal electrolyzed water used in the generating device 1 described above performs electrolysis with respect to the sodium chloride aqueous solution SA with an electrolysis current I of such a degree that each ion of Na + and ClO − in a high potential state is obtained. Thereby, it is the content which produced | generated the bactericidal electrolyzed water EW containing NaClO. The chemical reaction formula associated with the electrolysis is as follows.
Figure 2019030857
Figure 2019030857

2、O2については一部気化する。NaClについては電解中はごく一部が析出化され、結晶化し、水溶液上部に白濁状態で浮遊するが、電解を中止すると直ぐに溶解される。 Some of H 2 and O 2 are vaporized. As for NaCl, a small part is precipitated during crystallization, crystallizes, and floats on the upper part of the aqueous solution in a cloudy state, but dissolves immediately when the electrolysis is stopped.

Na,ClOについては高い電位状態であるため、NaClOとなり、可逆反応が殆んど生じることはなく、NaClOが含まれた水溶液となる。また、水溶液中ではNaClOが図3に示されるようにクラスター化され、その結果、非常に安定したイオン化物質のNaClOとなる。なお、図示されていないが、Naのイオンについても同様にクラスター化され、ClOのイオンについても除菌/殺菌に大きく関係すると考えられる。 Since Na + and ClO are in a high potential state, they become NaClO, and almost no reversible reaction occurs, resulting in an aqueous solution containing NaClO. In addition, NaClO is clustered in an aqueous solution as shown in FIG. 3, resulting in a very stable ionized substance NaClO. Although not shown, Na + ions are similarly clustered, and ClO ions are considered to be greatly related to sterilization / disinfection.

このように生成された殺菌性電解水EWは、次亜塩素酸を主成分とする水溶液であるが、NaClOの濃度が安定して維持される。その結果、殺菌性電解水EWの殺菌効果が従来の次亜塩素酸水に比べて高くなった。しかも殺菌性電解水EWの濃度やPHが6か月以上経過しても変化が見られないのが確認され、その持続時間も非常に長くなった。この点、従来方法を用いて生成された殺菌性電解水に少なくともNaClOの成分が含まれることはない。  The bactericidal electrolyzed water EW produced in this way is an aqueous solution containing hypochlorous acid as a main component, but the concentration of NaClO is stably maintained. As a result, the bactericidal effect of the bactericidal electrolyzed water EW was higher than that of conventional hypochlorous acid water. Moreover, it was confirmed that no change was observed even when the concentration of the bactericidal electrolyzed water EW and the pH were 6 months or more, and the duration was also very long. In this respect, the bactericidal electrolyzed water produced using the conventional method does not contain at least a NaClO component.

殺菌性電解水EWについては、一般的な除菌性に加えて、大腸筋、0157、サルモネラ菌及び黄色ブドウ球菌等のウイルスにも高い殺菌性を有することが実証され)、従来の次亜塩素酸ナトリウムやエタノールに匹敵又はそれ以上の殺菌効果が確かめられている(濃度:0.07PPM)。しかも次亜塩素酸ナトリウム等とは異なり安全性や持続性の問題がないことから、非常に有用な除菌/殺菌材となる。  Bactericidal electrolyzed water EW has been demonstrated to have high bactericidal properties against viruses such as colonic muscle, 0157, Salmonella and Staphylococcus aureus in addition to general sterilization properties), and conventional hypochlorous acid Bactericidal effects comparable to or higher than sodium and ethanol have been confirmed (concentration: 0.07 PPM). Moreover, unlike sodium hypochlorite and the like, there are no safety and sustainability problems, so it is a very useful disinfecting / sterilizing material.

上記した電解水生成方法による場合、殺菌性電解水EWの殺菌効果が高くなったことに加えて、その持続時間が長くなったことから、使用用途が現状以上に拡大される。例えば、畜産(鶏舎、豚舎、牛舎等 )等の殺菌、ウイルスの消毒、農薬の代わりに使用、野菜の洗浄、電解水EWで氷を作り、魚市場などの氷として使用、おしぼりに使用、飲食店、食品工場、病院、老人施設などの殺菌消毒に使用、養殖所の殺菌に使用、重篤なニキビ等の皮膚疾患の消毒、化粧水等が検討されている。また、塩化ナトリウム水溶液SAとして塩水を用いていることから、安全面及びコスト面でのメリットを期待することが可能となる。加えて、上記生成装置1は全体構成が非常にシンプルであることから、装置自体の低コスト化を図ることも可能になる。  In the case of the above electrolyzed water generation method, in addition to the fact that the bactericidal effect of the bactericidal electrolyzed water EW has increased, the duration of use has become longer, so the usage is expanded beyond the current level. For example, sterilization of livestock (chicken houses, pig houses, cow houses, etc.), virus disinfection, use in place of agricultural chemicals, washing vegetables, making ice with electrolyzed water EW, use as ice in fish markets, use for towels, eating and drinking It is used for sterilization of stores, food factories, hospitals, elderly facilities, etc., used for sterilization of farms, disinfection of skin diseases such as severe acne, and lotion. Further, since salt water is used as the sodium chloride aqueous solution SA, it is possible to expect merit in terms of safety and cost. In addition, since the entire configuration of the generation apparatus 1 is very simple, it is possible to reduce the cost of the apparatus itself.

なお、本発明に係る電解水生成方法については、塩化ナトリウム水溶液を用いて高電位状態で電気分解してNaClOのイオン化物質を含む殺菌性電解水を生成する内容である限り、使用する生成装置の構成が上記実施形態に限定されることはない。また、本発明に係る生成装置は上記実施形態に限定されず、以下のように設計変更しても良い。例えば、電源装置については、Na,ClOの各イオンが得られる程度の電解電流が生成可能であれば良く、電流制御方式を含めて適宜設計変更すれば良い。電極ユニットについては、アノード電極、カソード電極を電解槽内に保持する構成である限り、電極の材質、配置方法を含めて適宜設計変更すれば良い。 As for the electrolyzed water generating method according to the present invention, as long as the electrolyzed water is electrolyzed with a sodium chloride aqueous solution in a high potential state to produce bactericidal electrolyzed water containing an ionized substance of NaClO, The configuration is not limited to the above embodiment. Further, the generation apparatus according to the present invention is not limited to the above embodiment, and the design may be changed as follows. For example, the power supply device only needs to be able to generate an electrolysis current to the extent that Na + and ClO ions can be obtained, and may be appropriately changed in design including the current control method. As long as the electrode unit is configured to hold the anode electrode and the cathode electrode in the electrolytic cell, the design may be appropriately changed including the electrode material and the arrangement method.
