Description

[0002] Electrolyzer and control method of electrolyzer [

The present invention relates to an electrolytic cell, and particularly to an electrolytic cell in which a first electrolytic cell including an ion exchange membrane is provided upstream of a second electrolytic cell containing a diaphragm.

Conventionally, as a water purifier, generally, an electrolytic cell capable of continuously collecting electrolytic water is provided. For example, an anode chamber for generating acidic water by disposing a positive electrode in an electrolytic cell and a cathode chamber for generating alkaline water by disposing a negative electrode are provided And the water pipe is connected to the anode chamber and the cathode chamber so as to introduce the raw water and the acid water and the alkaline water can be taken out from the water intake pipe connected to the respective chambers.

Further, in order to provide an alkaline water with an improved dissolved hydrogen concentration, hydrogen ions generated in the anode chamber are moved to the cathode chamber by electroosmosis using a diaphragm composed of an ion exchange membrane, thereby to dissolve dissolved hydrogen gas particles in the cathode water (alkaline water) A water purifier is proposed. However, such a device requires a device for adding a redox substance and has a complicated device.

To solve such a problem, Japanese Patent Publication No. 4417707 discloses that two electrolytic cells are connected in series to include dissolved hydrogen gas particles in the cathode water.

The water purifier 1 includes an electrolysis section 3 having a water purification section 2 having a water purification tank 20 as a main component and a cartridge type for purifying raw water and a main electrolyzer 30 for electrolyzing purified water, So that they are housed in the box-shaped casing 10.

The electrolytic unit 3 includes a first electrolytic unit composed of a main electrolytic cell 30 having an anode chamber and a cathode chamber and a sub decontamination tank 40 for improving the dissolved hydrogen concentration of the alkaline water generated in the main electrolytic cell 30 cathode chamber And a second electrolytic unit constituted by the second electrolytic unit.

The sub decontaminating tank 40 has a first inlet 41a and a second inlet 41b and a second inlet 41b. The first inlet 41a and the second inlet 41a are connected to each other. And the second case 42b, which is provided with the second outflow channel 42b, is arranged so as to be watertight, so that the virtual center axis is orthogonal to the top of the main electrolytic bath 30.

Reference numeral 11 denotes a water pipe, reference numeral 12 denotes a water pipe, reference numeral 13 denotes an additive storage case, reference numeral 14a denotes an intake port, reference numeral 15 denotes an acidic water intake pipe, reference numeral 15a denotes a tip withdrawal port, reference numeral 16 denotes a communicating pipe, reference numeral 17 denotes a valve body, 50 is a clip-type connection port.

In order to increase the water pressure of the water supplied to the sub decontaminating tank 40, the water pressure of the raw water supplied to the main electrolytic tank 30 must be increased. However, when the water pressure is increased as described above, since water can pass through the diaphragm of the main electrolytic bath 30, there is a problem that the acidic water of the anode chamber flows into the alkaline water of the cathode chamber.

That is, the first electrode 230 and the second electrode 250 are provided as a perforated plate. The first hole is disposed in the first chamber, and the second hole is disposed in the second chamber. Due to the first and second electrodes 230 and 250, the distance between the electrode surfaces can be maintained constant, and ions can be smoothly exchanged through the first and second holes.

The first hole and the second hole are elongated in an oblique direction.

As shown in Fig. 8, the first hole and the second hole are disposed so as to intersect with each other, and the first hole includes a communicating portion communicating with the second hole and a non-communicating portion not communicating with the second hole .

[ The vertical cross-sectional shape of the control rod flow passage 111a may be a semicircle. As the flow rate adjusting rod 111 is rotated, the communicating area is changed to control the flow rate. In addition, a pedestal 111b protrudes from the middle of the control rod 111a of the flow rate control rod 111. [ Such a pedestal 111b prevents the flow rate adjusting rod 111 from being bent by the water pressure and facilitates the adjustment of the flow rate.

The outlet of the flow rate regulating flow path 123 joins the raw water outlet flow path 124.

The plunger 140 closes the inlet of the flow rate regulating passage 123 or closes the inlet of the flow passage formed in the valve seat 150. That is, as shown in FIG. 15A, the three-way valve allows the inflowing water to flow out directly to the raw water outflow passage 124, or the flow control valve 123 (see FIG. 15 ), And the flow rate is adjusted to flow out.

The control unit controls the flow rate control valve assembly 100 such that less water flows into the chamber where the electrode to which the anode is applied than the chamber where the cathode to which the cathode of the first electrolytic bath 200 is disposed is disposed. This minimizes the amount of wastewater and maximizes the amount of dissolved hydrogen-rich alkaline water. For example, when the negative electrode is applied to the first electrode 230 and the positive electrode is applied to the second electrode 250, the control unit controls the flow control valve assembly 100 to control the flow rate control flow path 123 to open the inlet of the flow control flow path 123 disposed on the right side so that water is discharged to the raw water outflow flow path 124 through the flow control flow path 123 To be discharged.

The amount of the wastewater can be minimized by providing the flow control valve 410 at the portion where the wastewater is discharged.

Further, the control unit controls the flow path switching valve assembly 400 so that the water discharged from the chamber in which the electrode to which the cathode is applied is discharged to the first water outlet pipe 404, So that the water discharged from the second water pipe 403 is discharged. For example, when the cathode is applied to the third electrode 330 and the anode is applied to the fourth electrode 360, the control unit may include a plunger 440 disposed on the left side as shown in FIG. 17 (a) So that the alkaline ionized water is discharged through the first water pipe connection channel 423 and the plunger 440 disposed on the right side is disposed at the lower portion to connect the second water pipe connection channel 405 to the waste water Water) is discharged. When the polarities of the electrodes of the first and second electrolytic cells 200 and 300 are changed, the control unit controls the polarities of the electrodes as shown in FIG. 17 (b).

Further, when the polarity of the electrode is changed, the controller supplies the raw water to the first electrolytic bath 200 for a certain period of time from the point of time when no alkaline ionized water is inputted (when the user does not use) The flow control valve assembly 400 is controlled so that the fourth chamber is connected to the second water outlet pipe 403 so that the electrolytic water generated in the third chamber and the fourth chamber are discharged to the second water outlet pipe 403 . This prevents the acidic water left in the electrolytic cell from being supplied to the user.

The electrolytic water supplied to the second flow path 311b flows into the second inlet 372 of the plurality of second frames 370 through the through hole formed in the lower end of the second flow path 311b and is supplied to the fourth chamber. The electrolytic water supplied to the fourth chamber is once electrolyzed to become acidic water. The acid water is discharged through the second outlet 373 and discharged to the second outlet 319a of the second electrolyzer.
