The raw water tank 10 is a tank for storing the water (raw water) to be electrolyzed. The raw water may be used tap water, fresh water, sea water, ground water.

The pump 12 is a device for transferring the raw water of the raw water tank (10). The pump 12 is preferably a metering pump.

The raw water passing through the pump 12 passes through the filter 14. The filter 14 filters various ions or impurities contained in raw water.

The raw water passing through the filter 14 is introduced into the anode chamber introduction line 40 and the cathode chamber introduction line 42, respectively. The cathode chamber introduction line 40 is provided with a mixing tank 16 in the middle, and the mixing tank 16 is connected with an electrolyte adding device consisting of an electrolyte tank 60 and an electrolyte pump 62 to add electrolyte. do. The electrolyte adding device may be connected to the anode chamber inlet line 40 immediately before the mixing tank 16.

Hereinafter, the strong acid water generation line and the weak alkaline water generation line will be described in detail.

(1) strong acid water generation line

The raw water passing through the filter 14 is simultaneously introduced into the anode chamber inlet line 40 and the cathode chamber inlet line 42, respectively, and moves. An electrolyte tank 60 and an electrolyte pump 62 are connected to the anode chamber inlet line 40, and a mixing tank 16 exists at a connection portion, whereby electrolyte and raw water flow into the mixing tank 16 and are mixed. . The electrolyte tank 60 stores a solution capable of acting as an electrolyte, that is, an electrolyte such as sodium chloride or calcium chloride. The electrolyte may be stored as a solid, but is preferably stored as a solution for the accuracy of the dosage. The electrolyte may be an inorganic acid such as hydrochloric acid, sulfuric acid, carbonic acid, nitric acid, or an organic acid such as acetic acid, citric acid, or hydroxyl acid. In the case of using the inorganic acid or the organic acid, it is useful when used to generate strong acidic water of lower pH.

As described above, in the present invention, the electrolyte is added only to the raw water introduced into the anode chamber 24 by connecting the electrolyte tank 60 only to the anode chamber inlet line 40.

The anode chamber inlet line 40 is connected to the lower portion of the anode chamber 24. The raw water mixed with the electrolyte is introduced into the anode chamber 24 to be electrolyzed. The electrolyzed water electrolyzed in the anode chamber 24 is strongly acidic, and the electrolyzed water is drawn into the strong acidic water storage tank 72.

(2) weak alkaline water generation line

The raw water passing through the filter 14 is introduced into the lower portion of the cathode chamber 26 through the cathode chamber introduction line 42. Unlike the positive electrode chamber introduction line 40, there is no electrolyte supply means, and thus, the mixing tank 16 is not interposed in the negative electrode chamber introduction line 42. Raw water without electrolyte is introduced into the cathode chamber 26 to be electrolyzed. The cathode water electrolyzed in the cathode chamber 26 is weakly alkaline, and the electrolyzed water is introduced into the weak alkaline water storage tank 74.

In this case, when raw water does not have an electrolyte like distilled water, a small amount of electrolyte, ie, sodium chloride solution, potassium chloride solution, and calcium chloride solution, may be introduced to enable electrolysis in the cathode chamber.

Since the weak alkaline water does not remove bacteria and the like contained in the raw water, it must be sterilized for use as drinking water. To this end, a sterilizer 64 was installed in the middle of the cathode chamber drawing line 46. The sterilizer 64 may be mounted on any one or two or more of the cathode chamber introduction line 42, the cathode chamber 26, the cathode chamber extraction line 46, and the weak alkaline water tank 72. The sterilization device 64 may use any one or two or more of various sterilization means, including a UV generator, an ozone generator, a heater, a UV generator-titanium oxide sterilizer, and the like.

In addition, the strong acid water- weak alkaline water generating apparatus according to the present invention, the pump 12, the filter 14, the electrolyte tank 60, the electrolyte pump 62, the mixing tank 16 and the electrolytic cell 20 and connecting them Various sensors (not shown) are connected to a pipe (not shown) and a valve attached to the pipe, and the pump 12, the electrolyte pump 62, and the electrolyzer 20 are connected to each other using data collected from the sensor. And a controller (not shown) capable of controlling various valves and the like.

Example 2

2 is a device conceptual diagram of another embodiment according to the present invention.

Referring to FIG. 2, the basic configuration of FIG. 2 is the same as that of FIG. 1, but the anode chamber connection line 48 / the cathode chamber connection between the electrolytic cell 20 and the anode chamber discharge line 44 / cathode chamber discharge line 46 is shown. It is different from FIG. 1 in that the water tank 70 and the multistage electrolyzer 22 to which the line 50 and the gas removal apparatus 66 are attached are additionally attached.

Hereinafter, the strong acid water generation line and the weak alkaline water generation line will be described in detail.

(1) strong acid water generation line

The primary strong acidic water electrolyzed in the electrolytic cell 20 is introduced into the lower portion of the second positive electrode chamber 28 of the multi-stage electrolytic bath 22 via the positive electrode chamber connecting line 48, and is electrolyzed once more in the second positive electrode chamber 28. It forms a secondary strong acidic water, and passes through the anode chamber lead-out line 44 is drawn into the strong acid water storage tank (72).

The raw water introduced into the anode chamber 24 has an electrolyte added thereto as in FIG. 1, and thus the electrolyzed water produced is strongly acidic.

Although not shown in the drawing, the cathode chamber connection line 48 may be provided with a reservoir 70 and an electrolyte addition device may be additionally connected to the reservoir. Further connection of the electrolyte addition device produces secondary strong acidic water with lower pH.

(2) Alkaline water generation line

The first weak alkaline water electrolyzed in the electrolytic cell 20 is introduced into the lower portion of the second negative electrode chamber 30 of the multistage electrolytic bath 22 via the negative electrode chamber connecting line 50, and once in the second negative electrode chamber 30. It is further electrolyzed to form secondary weak alkaline water, and is introduced into the weak alkaline water storage tank 74 through the cathode chamber drawing line 46.

At this time, since the gas (mainly hydrogen gas) is generated in the cathode chamber 26, in order to facilitate the electrolysis of the multistage electrolytic tank 22, a reservoir 70 is installed in the cathode chamber connection line 50, and the reservoir 70 The gas removal device 66 is attached to the gas to remove the generated gas.

Example 3

When the reverse voltage is applied in the strongly acidic water-alkaline water generator according to the present invention, the scale attached to the negative electrode plate may be removed by a conventional reverse voltage applying method in the order of constant voltage, reverse voltage and constant voltage. When a reverse voltage is applied, the generated electrolyzed water is discharged to the drain pipe.

Instead of using the conventional method as described above, it is possible to devise a method of less burden on the plate.

For example, the reverse voltage can be applied by the method shown in FIGS. 3A and 3B. Using the reverse voltage applying method of FIG. 3A, the value of the load drop of the electrode plate can be reduced by reducing the value of the vertical voltage drop in half. In addition, when the reverse voltage application method of FIG. 3B is used, the absolute value of the constant voltage gradually decreases gradually, thereby reducing the burden on the electrode plate. At this time, the absolute value of the constant voltage in Figure 3b may drop while drawing a parabola.

When applying the reverse voltage in the second embodiment, the two electrolytic cells may be timed to apply the reverse voltage so that reversal occurs in two or more electrolyzers at different times.

In all cases using the conventional method or using the method of FIG. 3A or 3B, the reverse display (part A in FIG. 3A or 3B) may be discharged through another discharge water line (not shown). An apparatus for changing the flow path between the positive and negative waters may be interposed between the electrolytic cell 20 and the positive electrode chamber discharge line 44 / cathode chamber discharge line 46 to prevent waste of electrolytic water. In the case of applying this method to the second embodiment, it is preferable to install the reservoir 70 and the gas removing device 66 in the anode chamber connecting line 48.

When electrolytic water is generated based on the above configuration, the positive water is a strong acidic water of pH3 or less, and the negative water is a weak alkaline water of pH 8.0 to 9.5.

As described above, according to the present invention, by introducing the raw water with the electrolyte added to the positive electrode chamber, strong acidic water is generated, and the negative electrode chamber is introduced with raw water without the electrolyte to generate weak alkaline water, but by sterilizing with a sterilizer, Strong acidic water is used to sterilize the sterilization target, and since the sterilized weak alkaline water can be used as drinking water for humans or animals, there is an effect that the used positive and negative water can be used without waste.
