However, in the above cited inventions,

It is a method to add special functional materials such as minerals in order to add functionality to the electrolyte or generated water commonly used in the electrolysis of water. A method of using electrolytic ionized water having the same properties as the product (minutes) as a composition for induction and generating a high level of electrolytic ionized water using the same has not been proposed.

In general, an electrolysis apparatus for water is provided with at least one pair of electrode plates that form a cathode and an anode in an electrolytic cell, and supplies electricity to each electrode plate for electrolysis. Such electrolysis devices can be classified into a diaphragm type having a diaphragm between the cathode and the anode, and a diaphragm type having no diaphragm.

Conventional electrolytic methods using a non-diaphragm electrolysis device have been able to increase the amount of electrolytic ion water generated when the voltage and current are increased and the number of electrode plates or the surface area of the electrode plates are increased, but there is a problem in that power is consumed.

Patent Publication No. 2001-69567, "Multistage Non-depth Electrolyte Ion Water Generator," discloses an electrolyzer having a high redox potential by constructing an electrolyzer in multiple stages to perform electrolysis at various stages, but the apparatus is not only complicated to install. There is no method of increasing the electrolysis efficiency without increasing the number of electrode plates.

In a conventional electrolysis device, an electrolyte having a high degree of ionization such as potassium chloride (KCl) or sodium chloride (NaCl) is used, and various minerals or necessary substances may be added to add functionality to the generated water.

When the electrolyte is added and electrolyzed using the diaphragm, strong acidic water is produced in the positive (+) chamber and strong alkaline water is produced in the negative (-) chamber.

Neutral or alkaline water is produced when the electrolyte is added but the membrane is electrolyzed. When electrolysis is performed using the membrane without the addition of the electrolyte, weakly acidic water is produced in the anode chamber, and weakly alkaline water is produced in the cathode chamber. Weak alkaline water is produced even when the electrolyte-free non-diaphragm electrolysis is performed.

There are two types of electrolysis methods: a continuous type of collecting electrolytic ionized water while continuously supplying water to an electrolytic cell, and a batch type of electrolyzed ionized water after electrolysis for a predetermined time by putting water in the electrolytic cell. However, the continuous type has a limit in the pH and redox potential that can be generated because the time for the generated water to pass between the electrodes in the electrolytic cell is extremely short.

In order to produce high pH electrolytic ionized water, it is necessary to increase the concentration of the electrolyte or reduce the flow rate of the produced water. However, increasing the concentration of the electrolyte increases the current, which promotes the electrolysis reaction, but the high concentration of chloride. Due to the inclusion of ions, there is a problem that a large amount of severe irritant gas is generated, especially in the anode chamber.

If the flow rate is reduced, the time for the generated water to pass between the electrodes in the electrolytic cell is long, so that water with high pH can be obtained. However, since the temperature of the electrode and the electrolyte is increased, the membrane is burdened and electrolysis cannot be performed for a long time.

On the other hand, it is possible to randomly set the time to apply the electrolysis voltage in a batch type, so that electrolytic ionized water with a higher pH can be generated compared to the continuous type. Since the equipment must be designed large, the whole apparatus becomes large

The present invention is to produce a high-reduced electrolytic ionized water of pH 12.5 or more by using a composition for inducing electrolysis and a method for solving the above problems.

The present invention is to devise a new circulation electrolysis method for the production of electrolytic ionized water in order to overcome the problems of the conventional continuous electrolysis device as well as the batch electrolysis device in water diaphragm electrolysis method, by developing a composition for induction It has the advantage that it is possible to manufacture highly reducing electrolytic ionized water of pH 12.5 or more which is difficult to reach with the conventional manufacturing apparatus.

In addition, it is possible to manufacture a large amount of water with a small electrolysis device, which has a distinctive feature in that a large amount of equipment is unnecessary.

In the water electrolysis device structure, a circulation structure consisting of an electrolytic cell, a production tank, and a circulation pump is provided.

Electrolysis device and composition for induction, characterized in that to increase the electrolysis efficiency without increasing the number of electrode plates, to produce a high level of electrolytic ion water by repeating the method of transferring to a storage tank when the number of production reaches the pH of the target level This method uses electrolytic ionized water of pH13.0 to pH14.0 containing 20,000 to 2,000 ppm of potassium hydroxide (KOH) as an active ingredient, and uses electrolytic ionized water of the same level as the electrolytic ionized water to be produced. .

The electrolysis device fabricated by the present invention facilitates the generation of strong alkaline electrolytic ionized water of pH 12.5 or more, and the strong alkaline water has strong sterilizing power, so that it can replace pesticides in agriculture and disinfectant disinfectants in food hygiene and medical fields. Have the effect of And strong alkaline water has high cleaning power, so it is used for general washing and cleaning of various industrial materials.

In addition, it does not contain any chemicals such as surfactants and alcohol is harmless to the living body and environmentally friendly. Therefore, this technology can replace the existing tax market.

The composition for inducing electrolysis of the present invention is a substance produced by the electrolysis device and production method of the present invention. This composition does not contain any other chemicals and has a strong alkalinity of pH 12.5 or higher containing a large amount of anion electrons when electrolyzed for about 180 minutes using a 25% aqueous solution of potassium carbonate as an electrolyte in a diaphragm electrolyzer. Electrolytic ionized water is produced.

The composition for inducing electrolysis of the present invention is an aqueous potassium hydroxide solution, but an aqueous solution that is completely different from potassium hydroxide. The chemical reaction formula of this composition is shown in <Figure 2>, and the chemical characteristics are shown in <Figure 3>. The composition of the present invention serves as a catalyst to readily generate high levels of electrolytic ionized water without changing the chemical properties of the resulting electrolytic ionized water.

The electrolytic ion water generating device according to the present invention includes a conventional diaphragm electrolyzer and an inflow passage formed at one side of the electrolyzer, an outflow passage formed at the other side of the electrolysis vessel, and a circulation pump and an outflow passage formed at the inflow passage. And it is desirable to have a program-embedded control device for changing the polarity of the electricity applied to the + and-plates of the electrolytic cell, or to control the pump operation.

This circulation arrangement type overcomes the shortcomings of the short electrode contact time in the conventional flow type method, and has the distinguished characteristic that enables the problem of being enlarged by the multi-stage electrode structure in the water tank type to the small size and light weight structure. If the electrolytic cell is operated for a long time, the temperature of the electrolytic cell rises and the electrolysis efficiency decreases.

In the electrolytic ion water production method according to the present invention, a predetermined amount of raw water is added to the generated water tank in a circulation arrangement, the composition for induction is added, and then a circulation pump is operated to perform electrolysis in the process of repeatedly generating the water through the electrolytic bath. After a certain period of operation, a new batch is started to discharge the generated electrolytic ionized water. In this way, alkaline electrolytic ionized water of pH 12.5 or more can be produced. If necessary, the induction material may be manufactured to be continuously added to the inlet or outlet.

Example (1)

When 20 liters of raw water is supplied to the production tank, and 2 liters of induction composition having a pH of 13.5 is added, the water in the production tank splits the clusters present in the water molecules by the electronic energy of the induction composition and simultaneously dualizes the water. Molecular structure is activated to reach pH9.5 instantaneously. At this time, if the water in the production tank is repeatedly circulated through the electrode of the electrolytic cell by operating the circulation pump for about 15 minutes, the electrolysis of the water is accelerated and the pH rises rapidly, and the molecular structure of the electrochemically changed product water is stabilized. Electrolytic ionized water of pH 12.5 or more which can maintain the characteristic of electrolytic ionized water for a long time is produced.

When the generated water reaches the target value, the generated water is discharged and the batch is finished. New raw water is supplied to the production tanks, enabling continuous production in the way the next batch begins.

The level of electrolytic ion water produced varies depending on the material and shape of the electrode, the distance between the electrodes, the amount of electricity, the type of diaphragm, the type and concentration of the electrolyte, the circulation rate and amount, the electrolysis time, and the quality of the raw water.
