Description

(4) The present invention relates to a preparation method for preparing electrolyzed water or raw water for electrolyzed water to be subjected to electrolysis, and to a preparation apparatus for preparing these electrolyzed water or raw water for electrolyzed water.

場合 When electrolyzed water is electrolyzed to generate electrolyzed water, electrolyzed water having various characteristics is generated depending on the electrolysis method. For example, in a diaphragm electrolysis system in which electrolyzed water is electrolyzed in a pair of an anode-side electrolysis chamber and a cathode-side electrolysis chamber partitioned by a diaphragm, acidic water (electrolytically generated acidic water) is generated in the anode-side electrolysis chamber, and In the cathode-side electrolytic chamber, alkaline water (electrolytically generated alkaline water) is generated. Further, for example, in a non-diaphragm electrolysis system in which the anode-side electrolysis chamber and the cathode-side electrolysis chamber are not partitioned, acidic water (electrolytically generated acidic water) is generated near the anode-side electrode, and alkaline water is generated near the cathode-side electrode. Water (electrolytically generated alkaline water) is generated, and neutral electrolytically generated water is generated at an intermediate portion between these two electrodes. In these electrolysis systems, the flow rate of the water to be electrolyzed in the electrolysis chamber and the voltage applied to both electrodes are controlled in order to obtain the electrolysis water having the set characteristics. In addition, by specifying the type and amount of components contained in the water to be electrolyzed, electrolytically generated acidic water having a different pH and electrolytically generated alkaline water having a different pH are generated. It is generated.

特性 In the generation of each of these electrolyzed waters, the characteristics of the electrolyzed water to be employed have a great effect in order to obtain the electrolyzed water with the set characteristics in a stable state. General water such as tap water or natural water is directly used as the water to be electrolyzed, or these general waters are used as raw water (raw water for electrolyzed water) in order to obtain electrolytically generated water having special characteristics. Electrolyzed water prepared by adding an appropriate inorganic salt or the like is used.

However, general water such as tap water or natural water used for the preparation of the electrolyzed water and the electrolyzed water contains various components, and the types of the contained components and Content varies considerably by region and environment. In general water such as tap water and natural water, for example, components of alkali metals such as sodium and potassium, components of alkaline earth metals such as calcium and magnesium are present in the form of cations, and chlorine components and carbonates. Components exist in the form of anions such as chloride ions and hydrogen carbonate ions.

In electrolysis using an aqueous solution containing a component of an alkaline earth metal such as calcium or magnesium as the water to be electrolyzed, CaCO ₃ , in the vicinity of the cathode-side electrolysis chamber of a diaphragm electrolyzer or the cathode-side electrode of a non-diaphragm electrolyzer, It is known that MgCO _{3 and the} like are deposited and adhere to the surface of the diaphragm and the surface of the cathode electrode, thereby greatly reducing the electrolysis efficiency and not being able to generate the electrolyzed water having the set characteristics in a stable state. ing. In order to cope with this, it is required to remove components of alkaline earth metals such as calcium and magnesium in the water to be electrolyzed. To cope with this, cation exchange is performed upstream of the diaphragm electrolyzer. There has been proposed an electrolyzed water generator in which a water softener containing a resin is arranged (see Patent Document 1).

By the way, in the water to be electrolyzed, a carbonate component is present in addition to the components of alkaline earth metals such as calcium and magnesium. And it was not possible to produce electrolytically produced water having the set characteristics in a stable state. For this reason, it is preferable that the electrolyzed water does not contain the components of alkaline earth metals such as calcium and magnesium and the carbonic acid component. It is preferable to use distilled water as raw water for electrolyzed water. However, there is a problem that a large-scale apparatus is required for generating distilled water, and a large cost is required.

This is a preparation device that is combined with the above. In the following description, the water to be treated by each means may be simply referred to as treated water.

When the cation exchange means and the cation exchanger in these preparation methods and preparation apparatuses contain Ca ²⁺ , Mg ^2+, etc. ^derived from various components in which the water to be treated is dissolved, The cation is replaced with H ⁺ , Na ⁺ , K ^+, etc., depending on the ion exchange group of the cation exchange resin used. Therefore, even when the water to be treated contains a calcium component or a magnesium component, the calcium component or the magnesium component is removed, and the ion-exchanged treated water has no calcium component or the magnesium component. It will be.

Further, the anion exchange means and anion exchanger in these preparation methods and preparation apparatuses contain Cl ⁻ , SO ₄ ²⁻ , HCO ₃ ^{− and the} like due to various components in which the water to be treated is dissolved. In such a case, these anions are replaced with OH ⁻ , Cl ⁻ , SO ₄ ²⁻ or the like depending on the ion exchange group of the anion exchange resin used.

When a large amount of air is blown into the water to be treated contained in the container in the form of bubbles, HCO ₃ ⁻ in the water to be treated is converted into CO ₂ and volatilized as CO ₂ gas. When the water to be treated is in the acidic region, it gradually shifts to the neutral region. Accordingly, when the water to be treated contains HCO ₃ ⁻ due to the carbonic acid component, the treated water has no carbonic acid component. However, water to be treated HCO ₃ ^- in the case containing the other anions, the anions remaining in the treated water. When it is desired to remove anions remaining in the treated water, an anion exchange means and an anion exchanger are used. In this case, the desired anion can be removed by selecting the type of the anion exchange resin to be employed. In the suction means, for example, by applying a negative pressure of the water to be treated contained in the container, the volatile components in the water to be treated are gasified and removed.

A diaphragm electrolyzer in the preparation method and the preparation apparatus according to the present invention includes an anode-side electrolysis chamber and a cathode-side electrolysis chamber.During electrolysis operation in the diaphragm electrolyzer, water to be treated is supplied to the anode-side electrolysis chamber.

Further, when the treated water (electrolytically generated water in the anode-side electrolysis chamber) is electrolyzed in the cathode-side electrolysis chamber, many anions are removed to become electrolyzed water in a substantially neutral region.

When such a special treatment system using the diaphragm electrolyzer is employed, HCO ₃ ⁻ resulting from the carbonic acid component contained in the water to be treated is easily converted into CO ₂ and converted into CO ₂ gas. to volatilize, but is not necessarily required to adopt the carbonate component removing means, HCO ₃ ^- in order to reliably remove the midway of the flow path of the anode electrolysis chamber and a cathode-side electrolysis chamber by the perforated membrane electrolysis Preferably, the above-mentioned carbonic acid component removing means and carbonic acid component removing device are interposed.

By appropriately selecting, water to be electrolyzed and raw water for electrolyzed water having desired desired characteristics can be prepared.

For example, an H-type ion exchange resin is used as the cation exchange resin used for the cation exchange means and the cation exchanger, and an OH type ion exchange resin is used as the anion exchange resin used for the anion exchange means and the anion exchanger. If an exchange resin is used, pure water will be used as final treated water. The pure water is one that can be suitably used as raw water for electrolyzed water for preparing electrolyzed water, compared to distilled water that can be used as raw water for electrolyzed water, and a simple preparation method and It can be prepared inexpensively with a simple and small preparation device.

Further, as the cation exchange resin used for the cation exchange means and the cation exchanger, a Na type ion exchange resin or a K type ion exchange resin other than the H type ion exchange resin is employed. By employing a Cl-type ion exchange resin or an SO ₄ -type ion exchange resin other than the type ion exchange resin and appropriately combining them, an inorganic salt (for example, NaCl, Electrolyzed water containing cations and anions such as KCl, Na ₂ SO 4, and K ₂ SO ₄ can be prepared.

The first preparation method according to the present invention is a preparation method comprising treating general water with a cation exchange means and treating the treated water treated with the same cation exchange means with an anion exchange means. FIG. 1 shows an embodiment (first preparation apparatus) of a preparation apparatus for performing the preparation method. The first preparation device A according to the present embodiment includes a cation exchanger 11 and an anion exchanger 12, and the cation exchanger 11 is an introduction pipe for introducing tap water, which is water to be treated. 11a, and an outlet pipe 11b for extracting the treated water. In addition, the anion exchanger 12 has an outlet line 12a for extracting the treated water, and is connected to the cation exchanger 11 via an outlet line 11b of the cation exchanger 11. . In the first preparation device A, the cation exchanger 11 incorporates a kind of cation exchange resin selected from the group of H-type ion exchange resin, Na-type ion exchange resin, and K-type ion exchange resin, Further, the anion exchanger 12 incorporates an anion exchange resin selected from the group of an OH type ion exchange resin, a Cl type ion exchange resin, and a SO ₄ type ion exchange resin.

In the first preparation apparatus A, tap water, which is water to be treated, is introduced into the cation exchanger 11 through the introduction pipe 11a, and the cation exchange resin contained therein is introduced into the cation exchanger 11. Undergoes cation exchange processing, and the treated water is discharged from the cation exchanger 11 through the discharge line 11b.

In the first preparation device A, the water to be electrolyzed and the raw water for electrolyzed water having desired characteristics can be prepared by appropriately selecting the cation exchange resin and the anion exchange resin. For example, if an H-type ion exchange resin is employed as the cation exchange resin incorporated in the cation exchanger 11, and an OH type ion exchange resin is employed as the anion exchange resin incorporated in the anion exchanger 12. The final treated water derived from the conduit 12a is pure water. The pure water can be suitably used as raw water for preparing electrolyzed water (raw water for electrolyzed water). In other words, in the first preparation device A, raw water (pure water) for electrolyzed water for preparing electrolyzed water is prepared. The raw water for electrolyzed water can be prepared inexpensively with a simple preparation method and a simple and small-sized preparation apparatus, as compared with distilled water that can be used as raw water for electrolyzed water.

Further, in the first preparation apparatus A, for example, a Na-type ion exchange resin is adopted as a cation exchange resin incorporated in the cation exchanger 11, and an anion exchange resin incorporated in the anion exchanger 12 is used. If a Cl-type ion-exchange resin is adopted, the final treated water discharged from the discharge conduit 12a becomes a dilute aqueous solution of NaCl containing NaCl. In other words, the first preparation apparatus A can prepare electrolyzed water suitable for generating electrolytically generated acidic water and electrolytically generated alkaline water by diaphragm electrolysis. In the first preparation apparatus A, if a combination of a cation exchange resin and an anion exchange resin to be used is appropriately selected, a dilute aqueous solution of an inorganic salt such as KCl, Na ₂ SO ₄ or K ₂ SO _{4 can be obtained.} Can be prepared.

In the second preparation method according to the present invention, the general water is treated by a cation exchange means, and the treated water treated by the cation exchange means is subjected to carbonic acid removal of a carbonate component contained in the treated water.

The myriad of bubble-like outside airs travel upward through the contained treated water while the bicarbonate ions (HCO ₃ ⁻ ), which are generated due to the carbonate component dissolved in the treated water, and the efficiency. Good contact converts HCO ₃ ^- to CO ₂ . The converted CO ₂ becomes gaseous and is released to the outside air through the gas outlet pipe 13d. As a result, the carbonated component is removed from the treated water contained in the vessel body 13a, and the treated water that has been removed from the outlet pipe 13c is water from which the carbonated component has been removed.

The treated water can be used as water to be electrolyzed because it contains an ion component effective for promoting electrolysis, and can be used to produce electrolyzed water having special characteristics. It can be used as raw water for electrolyzed water for preparing electrolyzed water. Therefore, according to the preparation apparatus B, treated water from which at least a calcium component, a magnesium component, and a carbonate component have been removed, which may have a bad influence on electrolysis, can be obtained.

In the electrolytically produced acidic water introduced into the vessel body 13a, HCO ₃ ⁻ resulting from the carbonic acid component is converted into CO ₂ in the vessel body 13a, and the carbonic acid component is released to the atmosphere as CO ₂ gas. The treated water from which carbonic acid has been removed by the carbonic acid component remover 13 is led out to the cathode-side electrolysis chamber R2 of the diaphragm electrolyzer 14 through the outlet line 13c, and is electrolyzed in the cathode-side electrolysis chamber R2 to become electrolyzed water. From the second outlet pipe 14e.

In the preparation device C, the tap water undergoes electrolysis in the anode-side electrolysis chamber R1 of the diaphragm electrolyzer 14 before being subjected to the carbonic acid component removing treatment by the carbonic acid component remover 13, and becomes electrolytically generated water. The electrolyzed water is in an acidic region from which many cations have been removed, and many metal ions including polyvalent metal ions such as Ca ²⁺ and Mg ²⁺ contained in tap water are removed. And the contained HCO ₃ ^- is easily converted to CO ₂ . For this reason, the carbonic acid component removal process in the process by the carbonic acid component remover 13 which is the next process of the electrolytically generated water is further assisted. The treated water from which the carbonic acid component has been removed is acidic, and when the treated water is electrolyzed in the next step, the cathode-side electrolytic chamber R2 of the diaphragm electrolyzer 14, many anions are removed. Therefore, it becomes electrolyzed water in almost neutral range. Therefore, according to the preparation apparatus C, it is possible to prepare water that does not contain at least polyvalent metal ions such as Ca ²⁺ and Mg ²⁺ and HCO ₃ ⁻ , using tap water as the water to be treated. In other words, good electrolyzed water or raw water for electrolyzed water can be easily prepared.

Note that, in these steps, if Ca ²⁺ and Mg ^{2+ are} slightly present, carbonate ions forming calcium carbonate and magnesium carbonate are removed from Ca ²⁺ and Mg ^2+. Therefore, it becomes calcium hydroxide and magnesium hydroxide. Since calcium hydroxide and magnesium hydroxide have high solubility in water, even if the water to be electrolyzed contains calcium hydroxide or magnesium hydroxide, calcium and magnesium components precipitate as scale during electrolysis and piping Does not adhere to electrodes, diaphragms and the like.
