The present invention relates to an apparatus for producing electrolytic sterilization water and a method thereof, and more particularly, to the most safe of chlorine disinfectants by electrolyzing water dissolved in sodium chlorite (NaClO ₂ ) using an ultra-small membrane electrolyte cell. The present invention relates to an electrolytic sterilizing water production apparatus and method for dissolving chlorine dioxide (ClO ₂ ) having excellent sterilizing power in an instant and very easily, to prepare sterilizing water and spraying the same.

As is known, disinfectants are substances used for sterilization purposes, and the types of disinfectants include chlorine (Cl ₂ ), chloramine (NH ₂ Cl), chlorine dioxide (ClO ₂ ), ozone (O ₃ ), ultraviolet (UV), and the like. There is this.

Generally, concentrations of disinfectant species of 1 ppm or less in aqueous solution are known to be able to kill a wide variety of microorganisms including bacteria, viruses, fungi, bacteria and spores. In addition, disinfectants with increased concentrations up to several hundred ppm can be used for various applications such as treatment of waste water or industrial water (eg cooling water), sterilization of fruits and vegetables, sulfite treatment in the petroleum industry, and textile or medical waste treatment. It is known to provide higher sterilization and oxidation effects.

On the other hand, the disinfectant has a function to remove phenolic taste and odor from water by reacting with and breaking down phenolic compounds, and cyanide, sulfide, aldehyde and mercaptan ( Chlorine (Cl ₂ ), which is the most commonly used among these disinfectants, is a chemically stable material, and has long-lasting and low-cost manufacturing costs, mainly for disinfection of tap water or homes and businesses. It is used for disinfection in the back. In addition, chlorine (Cl ₂ ) used as a disinfectant is mostly used as a solution of chlorine gas or sodium hypochlorite (NaOCl), and sodium hypochlorite (NaOCl) solution is usually distributed in a highly concentrated state, when handling Considerable safety precautions are required.

In addition, sodium hypochlorite (NaOCl) solution is not easy to be stored for a long time due to its high volatility, and is generally provided in high concentration, so it is cumbersome to dilute it every time in actual use, and the concentration when dilute is used. It is difficult to keep it constant at all times, so its scope and use is very limited.

In general, chlorine (Cl ₂ ) is a large amount of disinfection by-products that are carcinogenic when disinfection, these disinfection by-products are known to be very harmful to the human body. In addition, when chlorine is used as a disinfectant, a large amount of mutants resistant to chlorine may be generated among the existing germs, thereby reducing the effectiveness of disinfection, and most of them are very much in the examination of other disinfectants to replace the chlorine disinfectant. It is expensive or has a low disinfection effect and is difficult to replace due to difficulties in storage and management.

Representative disinfectants other than chlorine disinfectants include ozone (O ₃ ) and ultraviolet (UV) as described above. In the case of disinfectants such as ozone or ultraviolet rays, sterilization is excellent and there is no fear of disinfection byproducts. Although it is safe, it has no residuals, is expensive, and the processing process is complicated and difficult. In particular, ozone (O ₃ ) has an unstable characteristic in water, so there is a risk of regrowth of bacteria in the water, which is inconvenient to be used in combination with other disinfectants.

In addition, despite the same chlorine-based disinfectant, chloramine and chlorine dioxide, which have different properties from chlorine, have in common that they are relatively inexpensive in terms of cost and are safe because they generate very few disinfection byproducts. Disinfection effect is low, and chlorine dioxide is excellent in disinfection effect, but because it is difficult to dissolve in water, its treatment process is complicated and difficult, and is not suitable for home or business, and is mostly used for industrial purposes.

Since it is also used for the purpose of convenience, it will be referred to as an 'electrode holder'.

In order to allow the water inside the purified water tank (not shown) to pass through the interior of the electrolytic cell, the inlet hole 43a and the outlet hole 43b are formed on the surface of the electrode holder 43 according to the installation position thereof. The water inlet 43a and water outlet 43b are not particularly limited in number, but are preferably provided to the extent that the inflow and outflow of water can be made within the range that the total diameter does not exceed the electrolytic capacity of the electrolysis cell. . In addition, the inlet hole (43a) and the outlet hole (43b) is to be in communication with the electrolytic space 44 formed between the outer tube 41 and the inner tube tube 42, but sufficient to the water introduced into the interior of the electrolysis cell As shown in FIG. 6 or FIG. 8, the positions of the inlet hole 43a and the outlet hole 43b may be disposed in an up and down diagonal direction between the electrode holders 43 so that electrolysis can be performed. . In the present invention, the width of the electrolytic space 44, that is, the gap between the outer tube 41 and the inner tube 42 is preferably maintained to 0.5mm or less. More preferably, it is configured in the range of 0.2mm to 0.5mm.

In such a configuration, the water introduced through the inlet 43a, that is, the purified water W passes through the electrolytic space inside the electrolytic cell and is electrically operated between the positive electrode outer tube 41 and the negative electrode inner tube 42. Electrolysis by During electrolysis, oxidative mixtures such as chlorine, residual chlorine, ozone, OH radicals, and oxygen radicals are generated around the positive electrode, thereby oxidizing various microorganisms in purified water. Of course, the sterilization of such microorganisms is performed not only by indirect oxidation through oxidative mixture but also by direct oxidation which directly oxidizes the microorganisms by the positive electrode itself.

In the electrolytic cell according to the present embodiment, the material of the outer tube 41, which is a positive electrode, may be a relatively inexpensive titanium electrode or a low-cost electrode using a general injection product, instead of using expensive platinum-based metals. In the case of an electrode using a general injection molding, the surface of the injection molding may be provided by coating a platinum group RuO or Pt as a coating material. In addition, in the case of electrolyzing the purified water in the reverse osmosis filtration water purifier, the cell voltage supplied to the electrolytic cell of the present invention can be sufficiently operated at a low voltage of about 3 to 24V, even in such a condition, a sufficient amount of oxidative property The mixture can be generated to effectively sterilize purified water.

This fact is more clearly understood from the following experimental results.

Table 4 below shows the concentration of the oxidative mixture produced by applying a specific voltage and current to the purified water in the electrolytic cell of the present invention shown in Figures 6 to 8.

MO concentration compared to supply voltage and current Voltage (V) Current (A) MO (ppm) 12 0.02 0.08 16 0.06 0.16 20 0.09 0.18 24 0.13 0.23

* MO: oxidizing mixture

In this experiment, the supply flow rate of purified water to the electrolytic cell of the present invention was 100 ml / min, and the concentration of the oxidizing mixture contained in the purified water was initially provided at 5 ppm.

As can be seen from Table 4 above, the supply voltage 12V, 16V, 20V and 24V and the supply current 0.02A, 0.06 through the electrolytic cell for the water collected from the water purifier equipped with a reverse osmosis filter or ultrafiltration filter As a result of constant A, 0.09A and 0.13A, the oxidative mixture could be produced by adjusting the level to approximately 0.08 to 0.23 ppm. Even in this case, the taste of water was very good and microorganisms were not detected due to its excellent sterilization performance. On the other hand, when the oxidizing mixture generated as described above remains dissolved in the purified water for a predetermined period of time in a predetermined closed space such as a purified water tank, it is possible to naturally suppress secondary contamination by bacteria.
