[Prior Art] A well-known diaphragm type electrolyzed water device is disclosed, for example, in National Patent Publication No. 477833. The ion penetrating membrane is disposed between the anode and the cathode in the electrolytic cell. The anode and the cathode are separated from each other by an ion penetrating membrane so that β is electrolyzed to generate acidic electrolyzed water on the anode side and alkaline electrolyzed water on the cathode side. Another known membraneless electrolyzed water apparatus is disclosed, for example, in National Patent Publication No. 436,468. Since no ion-permeable membrane is provided between the anode and the cathode in the electrolytic cell, electrolytic water having a neutral, weak acid or weak base can be produced by electrolysis in such an electrolytic cell having no ion-permeable membrane.

It is still another object of the present invention to provide a multi-tank electrolyzed water generating apparatus 'for preparing functional electrolyzed water having functions such as sterilization, disinfection, cleaning, bleaching, oxidation or reduction. The above and other objects are attained by the multi-tank electrolyzed water generating apparatus defined in the independent application of the patent scope 200949017. Other advantageous forms are defined in each sub-item. The multi-tank electrolyzed water generating device of the present invention comprises a tank body and two partitioning devices. The tank system is divided into three tank units by a partitioning device. The partitioning device may be a watertight partition or an ion penetrating membrane. The separators are dependent on the separator used, and at least two of the three tank units are provided with an anode and/or a cathode. The apparatus of the present invention can elastically change the configuration of the separator and the electrode as needed to prepare electrolyzed water for various uses. © When the separator is a watertight partition, the anode and cathode are arranged in each tank unit. At this point, each cell unit acts as a diaphragmless cell, for example, for the preparation of weak acid, weak base or neutralized electrolyzed water. When one of the separators is a water-impermeable partition and the other partition is a separator containing an ion-permeable membrane, the anode and the cathode are respectively disposed in two separated by a separator containing an ion-permeable membrane. Slot unit. Further, the anode and the cathode are disposed in a cell unit away from the separator including the ion-permeable membrane and separated by the water-impermeable separator. In this case, the two cell units separated by the separator containing the ion penetrating membrane are used together to form a diaphragm type electrolytic cell, for example, for preparing acidic electrolyzed water on the anode side and alkaline electrolyzed water on the cathode side; Keep away from the cell unit of the separator containing the ion penetrating film, that is, the cell unit which is not in contact with or adjacent to the separator containing the ion penetrating film, in this case acts as a diaphragmless electrolyzer, for example, for preparing a weak acid , weak base or neutral water. When the separator includes a separator including an ion-permeable membrane, the anodes are disposed in one of the two groove units not adjacent to each other, and are disposed in the other of the two tank units not adjacent to each other 200949017 cathode. In other words, the cell unit which is simultaneously separated by the two separators containing the ion-permeable film is not provided with any electrode and is provided with a high concentration electrolyte solution, preferably a saturated concentration, more preferably a supersaturation concentration. In this case, unlike a diaphragmless electrolytic cell or a diaphragm type electrolytic cell, a cell unit which is separated by two separators containing an ion-permeable membrane (ie, a cell which is not provided with an electrode and is equipped with a high-concentration electrolyte solution) The unit) has a function similar to a salt bridge, and can prepare, for example, salt-free acidic and alkaline electrolytic water, respectively, on the tank unit on the anode side and the tank unit on the cathode side. The so-called salt-free electrolyzed water refers to an electrolyte component that is not used in the electrolyzed water. Advantageously, the partitioning means is replaceable to adjust the configuration of the baffles and electrodes as desired. Advantageously, the trough body includes a cover to prevent gas escape from the electrolysis process or to facilitate collection and/or further processing of the produced gas. Advantageously, a supply portion is provided on the tank body or on the closure for the injection of salts or compounds which can act as electrolytes and/or for the injection of electrolyte-containing solutions. Preferably, the supply portion may be provided in plurality or in correspondence with each of the groove units. Advantageously, an inlet for supplying unelectrolyzed liquid or raw water to the tank body and an outlet for discharging the electrolytically treated liquid or electrolyzed water from the tank body are respectively provided in the tank body. Preferably, the inlet and the outlet are each provided with one or a plurality of grooves corresponding to each of the grooves. It will be appreciated that liquid that has not been electrolytically treated may be supplied to the tank body via the supply. In contrast, a salt or a compound which can be used as an electrolyte or a solution containing a substance of 200949017 can also be supplied to the tank body via an inlet. According to the above disclosure, although a salt or a compound which can be used as an electrolyte, a solution containing an electrolyte, and a liquid system which is not subjected to electrolytic treatment are supplied to the tank body through respective inlets or supply portions, they may be supplied to the tank through a common supply portion or inlet. Slot body. In this way, the supply unit and the inlet need only be set one by one. The technical features of the present invention, as well as other objects and advantages, will be best understood from the description and appended claims. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The illustrated embodiments are merely preferred examples and are not intended to limit the scope of the invention. Figs. 1 to 3 show a multi-tank electrolyzed water generating apparatus 1 according to the present invention. The multi-tank electrolyzed water generating device 1 comprises a tank body 10 and two partitioning devices 12, 14, wherein the tank body 10 is divided into three tank units by means of the partitioning means 12, 14 〇1, 1, 〇.2, 1 〇.3. Separator 12, 14 can be selected from a watertight partition or a partition containing an ion penetrating membrane. The configuration of the electrodes (anode and cathode) will vary depending on the separator used, and will be explained in more detail below. Fig. 1 shows one of the possible configurations of the electrodes and separators of the multi-tank electrolyzed water generating apparatus 1 according to the present invention, wherein the partitioning means 12, 14 are each selected as a watertight partition. The trough body 1 is separated into three trough units 10.1, 10.2, 10.3 by partitions 12, 14. The tank unit 10.1 is provided with an anode 16.1, a cathode 18.1, an inlet 20.1 and an outlet 22.1. The trough units 10.2, 200949017 10.3 have the same configuration as the trough unit lo.i, and are each provided with anodes 16.2, 16.3, cathodes 18.2, 18.3, inlets 20-2, 20.3 and outlets 22.2, 22.3. In this case, the 'per-cell unit 1〇1, ι〇2, and ι〇_3 act as a diaphragmless electrolytic cell. Figure 2 shows another possible configuration of the electrodes and separators of the multi-tank electrolyzed water generating apparatus 1 according to the present invention, wherein the partitioning means 12 is a watertight partition and the partitioning means 14 is provided with a partition containing an ion penetrating membrane. board. The trough body 10 is divided into three trough units lo.i, Ο 10·2, 10, 3 by means of partitions 12, 14. The difference from Fig. 1 is that only the cell unit 10.1 is simultaneously provided with the anode 16.1 and the cathode 18.1, the cell unit 10.2 is provided with the anode 16.2, and the cell unit 10.3 is provided with the cathode 18.3. Although not shown, it is still promising that the tank unit 10.2 is provided with a cathode and the tank unit 10.3 is provided with an anode. In this case, the cell unit 10.1 acts as a diaphragmless cell, and the cell units 10.2, 10.3 act together as a diaphragm cell. Fig. 3 shows still another possible configuration of the electrodes and separators of the multi-tank electrolyzed water generating apparatus 1 according to the present invention, wherein the partitioning means 12, 14 are each selected to use a separator containing an ion-permeable membrane. The trough body 10 is divided into three trough units 10.1, 10.2, 10.3 by means of partitions 12, 14. The trough unit 10.1 is provided with an anode 16.1, the trough unit 10.3 is provided with a cathode 18.3, and the trough unit 10.2 is not provided with any electrodes. Each trough body has its own inlet and outlet, except that the trough 10.2 does not require an outlet. In the case where the slot unit 10.2 has an outlet set in advance, it is preferable to close the outlet of the slot unit 10.2. Hereinafter, a hypochlorite solution having a bactericidal function will be prepared by the apparatus of the present invention by taking an electrolytic saline solution as an example. 200949017 Please refer back to the multi-tank electrolyzed water generator 1 shown in Fig. 1. During the electrolysis process, at the anode of each cell, water h2o releases electrons to produce oxygen 02 and hydrogen ions H+, and chloride ions (:1_ release electrons to produce chlorine Cl2. Chlorine Cl2 is dissolved in brine, thus Hydrochloric acid HC1, hypochlorous acid HC10 and sodium hypochlorite NaCIO are produced. At the cathode of each cell, water H2〇 receives electrons e_ produces hydrogen H2 and hydroxide ions H_. Hydrogen oxide ions H_ combines with sodium ion Na+ Sodium hydroxide NaOH is produced. The anode and cathode disposed in each cell are not separated by an ion penetrating membrane, that is, each cell unit acts as a diaphragmless cell, so that the cell is electrolytically treated. The brine is weak acid or weak base. The cell unit 10.1 in Fig. 2 also acts as a diaphragmless cell, and the electrolysis reaction performed here is also as described above. The cell unit 10.2 and the cell unit 10.3 in Fig. 2 The groove unit 10.2 and the groove unit 10.3 act together as a diaphragm type electrolytic cell by being partitioned by a separator including an ion penetrating film, wherein the cell unit 1〇_2 configured with the anode 16.2 is an anode side electrolytic cell. , configured with a slot for the cathode 18.3 Element 1〇·3 is the cathode side electrolytic cell. At the anode of the anode side electrolytic cell, water H20 releases electrons e·produces oxygen 〇 2 and hydrogen ions H+, and chloride ion Cl_ releases electrons e· generates chlorine gas Cl2. Chlorine Cl2 is dissolved in brine, thus producing hydrochloric acid HC1, hypochlorous acid HCIO and sodium hypochlorite NaCIO. At the cathode of the cathode side electrolytic cell 'water H20 receives electrons e· generates hydrogen H2 and hydroxide ions OH·. Η· Combined with sodium ion Na + to produce sodium hydroxide NaOH. Since HCI and sodium hydroxide NaO 盐酸 are separated from each other by ion penetrating membrane, the electrolytically treated brine in tank unit 10.2 will be strong acid. In the tank unit 10.3, the brine treated by -10-200949017 will be a strong alkali. In the case shown in Fig. 3, the separators 12 and 14 all use a separator containing an ion-permeable membrane. The tank unit 10.2 is not provided with Any electrode' is equipped with a high concentration of saline, preferably a saturated saline solution, more preferably a supersaturated saline solution. At this time, the groove unit 1〇_2 acts like a salt bridge for electrical connection grooves. Unit 1〇·1 and slot unit 10.3. The cell unit 10.1 of 16.1 is an anode side electrolysis cell and is equipped with a solution containing no sodium chloride NaCl (ie, no salt), water or pure water, and a cell unit 10.3 equipped with a cathode 18.3 is a cathode side electrolysis cell and is loaded.塡 There is no (salt) solution of sodium chloride NaCl, water or pure water. At the anode of the anode side electrolysis cell, water H20 releases electrons to produce oxygen 〇2 and hydrogen ion H+. The cell unit v 10.2 is liberated through the ion-permeable membrane to the cell unit 10.1, and then electrons are released at the anode to generate chlorine gas Cl2. The chlorine gas Cl2 is dissolved in a solution containing no sodium chloride NaCl, thereby producing hydrochloric acid HC1 and hypochlorous acid HCIO. Compared to the first and second figures, sodium hypochlorite NaCIO is not formed on the anode side. At the cathode of the cathode side electrolytic cell, water H20 receives electrons e-produces hydrogen H2 ® and hydroxide ions. The sodium ion Na+ is released from the cell 10.2 through the ion penetrating membrane to the cell 10.3, and combined with the hydroxide ion OH to produce sodium hydroxide NaOH. Compared with the ones shown in Fig. 1 and Fig. 2, the difference is that the raw water supplied to the anode side electrolytic cell and the cathode side electrolytic cell without electrolytic treatment itself does not contain sodium chloride NaCl, so the anode side can be used in the electrolytic cell and the cathode. The side electrolysis cell prepares salt-free electrolyzed water. In the case of this example, a sodium hydroxide-free NaOH solution containing no salt can be prepared in the cathode side electrolytic cell. By the present invention, it can be further applied to the preparation of high-purity sodium hydroxide NaO. 200949017 In the anode side electrolytic cell (tank unit 10·1) and the cathode side electrolytic cell (tank unit 10.3), since the liquid does not contain sodium chloride NaCl, it is preferable to arrange the anode or the cathode as close as possible to the ion penetrating membrane. To facilitate conduction. Alternatively, in the initial stage of electrolysis, depending on the electrolysis product of each tank unit, for example, hydrochloric acid HC1 may be added to the anode side electrolytic cell, and for example, sodium hydroxide NaOH may be added as an electrolyte in the cathode side electrolytic cell to facilitate conduction. The electrolyte for preparing sterilizing water containing hypochlorous acid, although sodium chloride NaCl is exemplified in the above embodiment, is not limited thereto. Other chlorine-based electrolytes, chlorine-containing compounds or salts, alkali metal chlorides or alkaline earth metal chlorides such as potassium chloride KC1, calcium chloride CaCl2, magnesium chloride MgCl2, sodium hypochlorite NaOCl or hydrochloric acid may also be used. HC1 and so on. The electrolyzed water prepared by the device according to the present invention may be used directly or further, if necessary, adding an organic acid and/or an alcohol and/or a surfactant to achieve a change in its characteristics, such as changing the acid or alkali hydrazine or improving sterilization and disinfection. , cleaning and other capabilities. Although the arrangement of the electrodes in the above embodiment depends on the category ® of the partitioning means, it is advantageous to arrange the two electrodes in advance in each of the tank units without distinction. Since the so-called anode or cathode system depends on the electrode connected to the positive electrode of the power source or to the negative electrode, it is only necessary to change the connection between the electrode wires and the power source from the outside to achieve a substantially equivalent configuration to the above embodiment. For example, the connection between the interrupting electrode and the power source is interrupted, so that the electrode is left idle, and it can be considered that there is no electrode disposed. Further, for example, selectively connecting the electrode to the positive or negative electrode of the power source allows the electrode to selectively act as an anode or a negative electrode. In this way, the arrangement of the anode and the cathode can be easily carried out outside the electrolyzed aquatic product. While the invention has been described with respect to the preferred embodiments of the present invention, it is understood that many changes and modifications may be made to those of ordinary skill in the art to which the invention pertains, without departing from the spirit and scope of the invention. . Therefore, the present invention is not limited to the disclosed embodiments, but is intended to be in accordance with the scope of the appended claims. Coverage.
