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 raw water tank 10 may not be necessary in the case where the multistage diaphragm electrolytic water generating device according to the present invention is directly connected to the tap 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 flows into the mixing tank 30.

Even if the pump 12 is not a metering pump or a metering pump, a pressure reducing valve (not shown) is installed between the filter 14 and the mixing tank 30 in case the function of the metering pump is deteriorated. A bypass pipe (not shown) branched between the filter 14 and the decompression valve and directed toward the raw water tank 10 may be provided.

In the multistage diaphragm electrolytic water generating device according to the present invention, an additive liquid tank 20 is positioned separately from the raw water tank 10, and the additive liquid tank 20 includes an additive liquid, that is, sodium chloride solution, potassium chloride solution, and calcium chloride solution. Solutions that must be added to electrolyze water are stored.

The additive liquid tank 20 and the mixing tank 30 are connected by a pipe, and the additive liquid pump 22 is interposed therebetween. The pipe connected from the additive tank 20 to the mixing tank 30 is directly connected to a pipe connected from the filter 14 to the mixing tank 30 or is connected to an adjacent place of the raw water and the additive liquid. It is advantageous to mixing.

The additive liquid tank 20 and the additive liquid pump 22 may be omitted when electrolyzing the raw water without the additive liquid.

The pipe drawn out from the upper portion of the mixing tank 30 is drawn into the lower portion of the primary electrolytic bath 40. The electrolysis according to the present invention is a diaphragm type electrolysis in which the anode cell and the cathode cell are electrolytically interposed between the positive electrode and the negative electrode, so that the pipe introduced into the primary electrolytic cell 40 from the mixing tank 30 is positive and negative. The negative electrode is separated, and accordingly, the drawing shows two pipes separated from the mixing tank 30 into the primary electrolytic bath 40. The piping may be made in one, and the raw water may be separated by separating the anode cell and the cathode cell into the primary electrolytic cell 40.

The primary electrolyzer 40 electrolyzes the introduced raw water, and the electrolyzed primary electrolyzed water is withdrawn to the upper portion of the primary electrolyzer 40. The primary electrolyzed water is drawn out in two lines as raw water is drawn in. The cathode water generated in the cathode cell of the primary electrolyzed water includes a gas (mainly hydrogen gas) generated inside the primary electrolyte tank 40, and prevents the gas from remaining in the primary electrolyte tank 40. In order to do so, the primary electrolyzed water is preferably withdrawn to the upper portion of the primary electrolytic bath 40.

Positive and negative water, which are primary electrolyzed water extracted from the primary electrolytic bath 40, are introduced into the positive and negative water reservoirs 50 and 52, respectively. The reservoirs 50 and 52 may also buffer the flow of primary electrolyzed water between the primary electrolyzer 40 and the secondary electrolyzer 42. In particular, since the gas (mainly hydrogen gas) transferred from the primary electrolyte tank 40 together with the cathode water in the primary electrolytic water is collected on the upper portion of the cathode reservoir tank 52, the gas is removed from the upper portion of the cathode reservoir tank 52. Apparatus 56 may be installed to remove the gas. In addition, since the positive electrode and the negative electrode of the primary electrolytic bath frequently apply a reverse voltage to remove the scale attached to the electrode, when a constant reverse voltage is applied to the positive electrode reservoir 50, since the negative water is introduced, the gas removal device 54 is provided. You can also install). The degassing device (54, 56) may use known parts that pass only gas, but not water, and check the amount of gas collected in the reservoirs (50, 52) to ensure that the amount of gas is constant. If exceeded, various degassing devices 54 and 56 may be used.

Although the cathode reservoir 50 and the cathode reservoir 52 are shown as being separated in the drawing, the cathode reservoir 50 and the cathode reservoir 52 are formed as one and configured to be separated into a partition wall. It may be.

When the degassing apparatuses 54 and 56 are not installed in the reservoirs 50 and 52, the primary electrolyzed water drawn out from the primary electrolyte tank 40 is introduced into the lower portions of the reservoirs 50 and 52. It is preferably drawn out to the top of the reservoirs (50, 52).

When the gas removal devices 54 and 56 are installed in the reservoirs 50 and 52, the primary electrolyzed water drawn out from the primary electrolyte tank 40 is introduced into the middle or the upper portion of the reservoirs 50 and 52. It is preferable to be drawn out to the lower portion of the reservoirs (50, 52).

Similarly, the positive water drawn from the positive electrode reservoir 50 is the positive cell of the secondary electrolytic tank 42, and the negative water drawn from the negative electrode reservoir 52 is introduced into the negative electrode cell of the secondary electrolytic bath 42. do. The primary electrolyzed water introduced into the secondary electrolytic bath 42 is electrolyzed as in the primary electrolytic bath 40. In the secondary electrolytic bath 42, those that have not been electrolyzed in the primary electrolytic bath 40 are further electrolyzed. As in the primary electrolyte tank 40, since the gas (mainly hydrogen gas) is generated in the cathode cell of the secondary electrolyte tank 42, the electrolytic secondary electrolyte water is preferably drawn out to the upper portion of the secondary electrolyte tank 42.

The secondary electrolyzed water drawn out from the secondary electrolyzer 42 is moved to the electrolytic water storage tank 60 and stored. The electrolytic water storage tank 60 is to be accommodated by separating the positive and negative water, it may be formed by separating the positive and negative storage tank and the cathode storage tank in some cases.

A drain valve is interposed between the secondary electrolyzer 42 and the electrolytic water storage tank 60 to discharge electrolyzed water initially generated when the multistage diaphragm electrolyzed water generating device according to the present invention is not operated and operated. You can do that.

The electrode plates 402 and 404 may use a plate coated with platinum on a titanium plate, and a general iron plate or a carbon plate may be used, but a plate coated with iridium on the titanium plate is preferable.

The space 406 insulates the electrode plates 402 and 404 and forms a flow path of water to be introduced therein. The space 406 is designed to maximize the contact of the water flow path with the pole plates 402 and 404 attached to the side of the space 406. The space 406 may be changed in various shapes.
