Description

Electrolysis Apparatus for manufacturing Sterilized water using electrode combination}

The present invention relates to a sterilizing water production apparatus that can be used to create a sterilized water containing a mixed oxidant using a combination of electrolysis electrodes for electrolyzing water, and more specifically, a certain size and time for electrolyzing general water is required. The present invention relates to a device for producing sterilized water, which reduces the cost of manufacturing electrodes by generating a highly efficient mixed oxidant and increasing durability of the electrode by using materials and characteristics of the electrolysis electrode in the reactor and a combination of the electrodes.

Chlorine is widely used as a disinfectant for water treatment because of its simple handling, relatively easy management of residual concentrations, and low operating costs. However, protozoans resistant to chlorine have been detected, and there is a disadvantage in that a large amount of chlorine needs to be injected to disinfect them effectively. On the other hand, when a large amount of chlorine is injected, there is a risk of increasing the production of chlorine hydrate, HAAs (Haloacetic acids) and THMs (Trihalomethanes), which are harmful by-products, which are harmful to the human body. Due to these limitations, interest in the process of replacing chlorine disinfection has increased, and research into the electrochemical process of electrolyzing water as an alternative disinfection method is actively conducted. Electrochemical disinfection is an environmentally friendly process in that electrons are used, unlike conventional disinfection methods using chemical disinfectants. In addition, the process is easy to automate, the operating cost is low, and mixed oxidants such as O ₃ , H ₂ O ₂ , OH (OH radical) and HClO (hypochlorous acid) are produced simultaneously with chlorine to remove disinfection effect and organic matter. There is an advantage that it can.

In this electrochemical method, the electrode is mainly platinum-plated on titanium, and some of the mixed oxidants have a greater sterilizing ability only after a certain time of reaction in a reaction tank in which an electrolysis reaction occurs. The reactor space should be reduced and the reaction time should be reduced below. In this case, the mixed oxidizer generator using the existing electrode was inadequate, and there was a problem in that the overall sterilization ability of the sterilization water was reduced.

Therefore, the present invention was invented to solve the conventional problems as described above, the object of the present invention by combining the electrode of the platinum plated on the existing titanium and the electrode of the new material HClO (excellent bactericidal power even when reducing the reaction space and reaction time ( It is to provide a sterilizing water production apparatus containing a mixed oxidant such as hypochlorous acid).

According to a feature of the present invention for achieving the above object, the present invention uses a platinum-plated titanium, zirconium electrode combination and platinum-plated zirconium electrodes, to make at least a pair of electrodes comprising an anode and a cathode In the sterilizing water production apparatus including a mixed oxidant, characterized in that it comprises a power supply for applying power to the pair of electrodes, the electrode is a flat plate, a plate type, a plurality of holes are formed, It may be in the form of any one of the cylinders.

In this case, a coating layer is formed on a part or the whole of the electrode surface, and the components of the coating layer are composed of platinum compound, iridium compound, tin compound, titanium compound, palladium compound, tantalum compound, rhodium compound, ruthenium compound, or a combination thereof. It may be selected from the group.

The power supply unit may include a control panel or an operation button for applying power to the pair of electrodes, and may change the direction of the electrode supplied to the pair of electrodes through the control panel.

According to the electrolytic sterilizing water production apparatus using the electrode combination according to the present invention can be expected the following effects.

In other words, by using platinum-plated titanium, zirconium electrodes and platinum-plated zirconium electrodes as electrodes of a sterilizing water production apparatus including a mixed oxidant, it is possible to increase the production efficiency of mixed oxidants and to improve durability by improving the cost of the electrodes by using a platinum-plated titanium, zirconium electrode and platinum-plated zirconium electrodes. There is an advantage to reduce.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the electrolytic sterilizing water production apparatus using the electrode combination according to the present invention as described above will be described in detail.

1 is a block diagram showing a schematic configuration of an electrolytic sterilizing water production apparatus using an electrode combination using an electrode combination according to a specific embodiment of the present invention.

As shown in FIG. 1, the apparatus for producing electrolytic sterilized water using an electrode combination according to a specific embodiment of the present invention includes a container in which water is electrolyzed and a pair of electrodes installed in the container.

The vessel provides a space for the electrolysis of water to produce sterile water containing mixed oxidants.

The electrolysis reaction is generated by supplying a direct current to the pair of electrodes.

The DC current is supplied by the DC power jack 30.

In a specific embodiment of the present invention, the electrode is described as a metal lath mesh, but is not necessarily limited thereto. That is, the electrode may be formed in a flat plate shape, a flat plate shape having a plurality of holes or a cylindrical shape.

It is provided with a control pad or an operation button for driving the PCB 20 separately. In addition, in order to solve the problem of erosion of the electrode may be to be alternately driven through the direction of the current through the PCB (20).

Briefly, the order of mixed oxidant formation is described by O and O ₂ formed by electrolysis of water. The molecules combine to form ozone. Next, hydrogen peroxide is produced by the electrolysis of oxygen or by the bonding of OH radicals, which are intermediate products produced by the decomposition of ozone.

After Cl ⁻ ions present in the water bind with Cl ₂ , HClO is generated by reaction with H ₂ O.

The OH radical is if the direct measurement is not possible, but the ozone due to disappear was instantaneously present in the water, OH ^- or the conjugate base of HO ₂ of the hydrogen ^{peroxide-forming} a and radical chain cycle reaction, and finally the OH To generate radicals.

Microorganisms present in water are inactivated or removed by the resulting mixed oxidant. That is, bacteria are removed by electrosorption and other microorganisms are removed by direct electrolysis by reaction with e ⁻ . Looking at this in more detail, it is as follows.

Scheme 1

Microorganism → Electrosorption → Inert

M + O ₃ → inactivaton

M + OH ^- → inert (Inactivaton)

M + HClO → Inactivaton

Scheme 2

Microorganisms ^{(Microorganics) → e - → M} -

M + O ₃ → Product

M + OH ^- → Product

M + HClO → Product

That is, the oxidation and sterilization is smoothly performed by the mixed oxidants (O ₃ , H ₂ O ₂ , HClO, OH radicals) generated during the electrolysis of water. After the electrolysis is performed, high sterilizing power is maintained by high residual HClO and anion.

Looking at the efficiency of the electrode combination in a specific embodiment of the present invention are as follows.

division Titanium electrode Titanium / Zirconium Electrode Zirconium electrode FAC (ppm) 0.48 0.67 0.80 efficiency 100% 139% 166%

The above data is the average value measured 10 times of FAC (free active chlorine) after operating for 30 seconds by applying 18V DC voltage in 300cc of tap water at room temperature.

In this case, a 50 mm * 50 mm square mesh electrode plated with platinum was used.

As described above, according to the electrolytic sterilizing water production apparatus using the electrode combination according to a specific embodiment of the present invention, the performance and efficiency is better than the mixed oxidizer generator using the conventional titanium electrode combination, reaching the same FAC Reduced time has an advantage of increasing the use time of the electrode, lowering the manufacturing cost of the electrode.
