BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier sterilization apparatus for sterilizing bacteria in water, and more particularly, to an apparatus for sterilizing bacteria in a water tank in a reverse osmosis type home water purifier, which has recently increased in use.

An example of a conventional water purifier sterilizer for solving such a problem of bacteria is a sterilizer as shown in FIG.

1 is a rear view of a water purifier sterilizer according to the related art, and FIG. 2 is a flow diagram of a water treatment system of the conventional water purifier shown in FIG.

Referring to the drawings, the tap water supplied from the water pipe is removed by the micro filter 48 to remove the primary suspended solids and sand and other solids, and the pressurized water from the pressure pump is sent back to the carbon filter 47. At this time, the carbon filter 47 removes most of the taste, chromatic chlorine and other toxic organic substances which are not removed from the micro filter 48, and sends the relatively clean water to the reverse osmosis membrane filter (R / O membrane) 46. The membrane filter 46 removes heavy metals and other metal ions that are not removed from the carbon filter 47 and fine organic and inorganic materials such as bacteria and the like.

The water treated as described above is passed back to the water storage tank, that is, the sterilization tank 42 and stored after passing through the carbon filter 44 for the second more reliable treatment.

In the conventional water treatment process as described above, after passing through the micro filter 48, the ultraviolet sterilization filter 45 is installed to sterilize, and is sent to the water storage tank 42 to be stored for a long time. Before entering the water storage tank 42, bacteria are removed from the reverse osmosis membrane (R / O membrane) filter 46, and then sterilized by the ultraviolet filter 45 and then stored. In this case, the bacteria may be initially removed, but after the water is stored in the water storage tank 42 for a long time, bacteria generated in the water tank 42 and bacteria floating in the air flow into the water storage tank 42. There is a problem that a lot of bacteria increase in the tank 42.

That is, the water passing through the reverse osmosis membrane filter 46 in the water purifier passes through the ultraviolet sterilizer (filter) 45 to be sterilized in a considerable amount, but the water passing through the ultraviolet sterilizer 45 is stored in the water storage tank 42. After a long time, pathogenic bacteria such as general bacteria and Escherichia coli in the air are infiltrated into the water tank 42. Therefore, when used for a long time in the above state, the water storage tank 42 is contaminated with bacteria, so there is virtually no way to deal with damage to bacteria.

In particular, water purifiers using membranes have to store water for a very long time because the amount of water produced is very small, and the storing water removes chlorine, etc., which are added for sterilization in the water treatment plant by the membrane and by the membrane. By removing most of the minerals, or minerals, contained in the water, which have antibacterial properties, the water stored after purification in the tank may be very clean in its initial state, but the growth conditions of bacteria due to the removal of the antimicrobial substances over time It had a problem of betrayal that well satisfies.

In addition, there is another conventional method for solving the above problems, there is a method of injecting ozone gas into the water tank, but this is also a tank for storing immediately before the drinking bar, leaving ozone odor in the water during drinking and ozone Another problem is caused by the rather blowing of contaminants into the air from a compressor or the like used to continuously blow the gas. In addition, there is a problem that the oxidation of the water tank or the fishy smell is caused by ozone gas.

Therefore, the present invention in view of the above problems by applying electrochemistry to increase the hydroxyl group (hydroxyl radicals) in water to sterilize the bacteria, and after sterilization using a cycle of electrochemistry that returns to the original by decomposition or reduction The aim is to provide a groundbreaking drinking water sterilizer that does not cause any obstacles in drinking water and produces no other by-products.

Water purifier sterilization apparatus of the present invention for achieving the above object is a micro filter for primary removal of impurities made of suspended solids or other solids contained in the tap water supplied in connection with the water pipe; A pump into which water passing through the micro filter is introduced; A first carbon filter which secondly removes chlorine and most other organic substances which are not removed from the micro filter by flowing water pressurized by the pump again; A reverse osmosis membrane filter into which water that has passed through the first carbon filter is introduced and removes metal ions and other toxic organic substances which are not removed from the first carbon filter; A second carbon filter into which water passed through the reverse osmosis membrane filter is introduced again; Water passing through the second carbon filter is stored, and two electrodes, a positive electrode and a negative electrode, which are capable of applying a voltage therein, are installed. A sterilization tank in which bacteria are sterilized by radicals; Characterized in that the configuration including the cold water and hot water tank supplied with purified water from the sterilization treatment tank.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the water purifier sterilizer according to the present invention.

First, the basic technology required to achieve the object of the present invention will be described.

In general, when an electrode is installed inside a bucket and electrical energy is applied thereto, different chemical reactions occur at the two electrodes. I.e. (+) it occurs and the oxidation reaction in the positive electrode (Anode) was added electricity (Oxydation), (-), and a reduction (Reduction) In the cathode (Cathode) was added electricity occurs, and a hydroxyl group in water and hydrogen is generated (OH ^- ), Ie, the hydroxyl radical increases. (4H ₂ O → 4OH + 2H ₂ ↑) (See Fig. 11)

In more detail, the anode reaction is called OH ⁻ discharge, which cannot be explained simply by the process of anode reaction by Anion discharge, but in many cases, OH ⁻ discharge occurs in aqueous solution. The overall reaction is _{^{4OH - → 2H 2 O + O}} 2 + as 4e The reversible potential ^{_{E 02R = R 2 0 + (}} RT / 4F) In (a 2 H2O and PO ₂ / a ⁴ OH ^-) shown as being 24 ⁰ In C, E4 ₂ ⁰ = 0.3976V.

The electrode voltage, of course, also varies depending on the current density, the surface state of the electrode material and the electrode, and the experimental conditions thereof, but does not have regularity in the case of H + discharge. In this case, they are generally smaller in Co, Fe, and Cu and larger in Pt and Au. In addition, cathode reaction is a discharge of hydrogen ions (hydrogen overvoltage) as described above, and the overall reaction is 2H ₃ O ⁺ + 2e → H ₂ + H ₂ O.

On the other hand, when explaining the characteristics of hydrogen overvoltage, the magnitude of the overvoltage experimentally at a density of IN HCL solution I = 1x10 ^-2 A / cm2, depending on the temperature of the electrode and lowering and depending on the electrode chemical properties, experimental conditions, and purity of the material Are generally Pt-Pt, Rh, Au, W, Dt, Ni, Mo, Fe, Ag, Al, Be, N3, Ta, Cu, C, Bi, Pb, Sn, In, Tl, HG, Cd Because of its size, it is necessary to check this problem closely in order to apply the present invention.

In addition, the main process due to overvoltage can be considered as follows because it is influenced by substances affecting the surface condition pretreatment of the pole, hydrogen pressure, solvent properties, and the amount of electrolytes in the solution. Can be.

1) Adsorption on electrode metal M of H ⁺ to reduction to H

H ₃ O ⁺ + e + M → H (M) + H ₂ O

2) Molecular hydrogen of H bonds with H2

H (M) + H (M) → 2M + H ₂

Or (b2) H ⁺ combines with H on the electrode and is simultaneously reduced.

There is a process of H (M) + H ₃ O ⁺ + e → M + H ₂ + H ₂ O, and of course, as described above, the result of the above reaction is the amount of electrolyte, that is, the metal ions contained in water ( It is true that the amount becomes large depending on the amount of the electrically conductive material of METALION).

Then, in the R / O type membrane water purifier tank to be applied to the present invention, the amount of electrically conductive material, that is, metal ions is very low compared to the general. Because significant amounts of metal ions have been removed by the membrane, sufficient energy must be applied to induce an efficient electrode reaction. However, another thing to be aware of here is that if an abnormality occurs when the high voltage is applied and the original water that is not treated by the membrane enters the tank or the salt enters, the electrical conduction increases and the water Since this can cause problems, it should be protected against this.

In the present invention, in consideration of the above-mentioned problems, the protective device is designed separately, and in particular, it is configured so that no obstacle occurs in consideration of problems that may occur when the electrode is exposed when there is no water.

In addition, in the cathode (-) due to the electrode reaction occurring at the cathode and anode, there is a problem that (+) ions stick to the electrode and interfere with electrical conduction when used for a long time, so 30 minutes or 1 hour or an appropriate interval for solving this problem By configuring the circuit so that the polarity applied to the electrode is replaced (alternately), the current direction is periodically changed to prevent the adhesion of the metal ions deposited from the electrode and to maintain the performance of the electrode semi-permanently.

In addition, another reason for crossing the polarity of the electrode voltage at regular intervals is that the metal ions precipitated at the reduction electrode are released again in the water tank, and there is also a reason for further increasing the sterilization efficiency of bacteria due to the dynamic effect.

In addition, when the conductivity is increased due to tearing of the membrane or other causes, the electrode reaction is much increased, but only the purpose of blocking the electric circuit and disinfecting bacteria in the water tank for a long time is achieved. It is not necessary to induce excessive aggressive reactions.

What is to be obtained here are radicals such as OH ^- radicals and oxygen generated by the electrode reaction.

As shown in Table 1 below, the OH radical acts to sterilize bacteria as a material having a high oxidation potential next to fluorine (F ₂ ). Of course, ozone or chlorine (Cl) is also involved in sterilization, but as shown in the table, since the oxidation potential is lower than that of OH radicals, the sterilizing power is high in OH radicals. However, as another method to be aware of here, the method of generating ozone by this electrode reaction has been known for a long time, briefly described as follows.

Electrolyzing an acidic solution such as sulfuric acid usually causes water to decompose to produce an oxygen and hydrogen generating reaction as shown in the following equation.

Anode 2H ₂ O → O ₂ + 4H ⁺ + 4e ^- E ₀ = 1.23V

Cathode 4H ⁺ + 4e → 2H ₂ E ₀ = 0.00V

Forward 2H ₂ O → O ₂ + 2H ₂ E ⁰ = 1.23V

On the other hand, ozone generation in combination with oxygen generation under special conditions is based on the following equation.

3H ² O → O ₃ + 6H ⁺ + 6e ^- E ⁰ = 1.5IV

Since the ozone generation reaction potential is higher than that of the oxygen generation reaction, and in parallel, oxygen generation occurs preferentially, in electrolysis for the purpose of ozone generation, special conditions for suppressing oxygen generation as much as possible are necessary. For this reason, in order to generate ozone, it is necessary to make the anode potential high, that is, excessive current density and electrolysis at a lower temperature.

In general, since the current density of several times to several tens of times than the electrolytic method involves very large heat generation, the cooling of the liquid is insufficient and the internal cooling method that cools itself must be adopted. Applicable to the device.

At this time, a high concentration of sulfuric acid, perchloric acid, phosphoric acid and the like are used as the electrolyte solution, and the cathode material is limited to platinum having a high oxygen overvoltage. Therefore, ozone generation by electrolytic method is somewhat problematic to apply to the water purification device of the present invention, when using a positive electrode of lead dioxide and a high concentration of phosphate aqueous solution, ozone may be generated even in relatively mild conditions, but in this case it is used in drinking water used as drinking water In the following, there is a problem in using it because it has an effect on smell or taste.

In addition, the conductivity of the water passing through the membrane is very low, which is a problem to meet the above conditions, especially in the membrane-type water purifier, through the membrane, enough filtered water is stored in the water tank and flows directly to the outlet It also has some problems, given that it is used as water and has limited conditions that should not leave any smell or taste in the water.

However, in the present invention, as shown in FIG. 3 (a) and FIG. 3 (b), the electrodes 1, 4 made of materials which do not cause any pollution are installed in the sterilization tank (water tank) 3 When alternating DC current flows at regular intervals, the electrode reaction occurs at both electrodes 1 and 4.

At this time, before it said oxygen gas and hydrogen gas generated is the hydroxyl radical gas (HO ^-) in the air during the bacteria that is falling bacteria Staphylococcus aureus or the like from entering the inside of the tank (3) primary and disinfection, occurring at the electrode OH ^- is a radical also sterilize the bacteria in the water. At this time, since the OH radical is very fast in its reaction rate, it does not leave any pollution in water and is directly reduced to H ₂ O, so it is possible to achieve the purpose of sterilization without problems in water.

On the other hand, metal ions, such as Ca ⁺ , Mg ⁺ , Ag ⁺ , K ⁺ , which are moved by the electrode reaction, move from left to right to left in FIG. 8 depending on the alternating polarity of the electrode. It is moved as shown. At this time, the oligodynamic effect of the metal ions generated (adsorbed anion to the carbon to release the anion in the water has been used as a method of inhibiting or sterilizing the growth of bacteria) shows the bactericidal and inhibitory effect of the bacteria.

In particular, hydroxyl radicals generated at the electrode are involved in sterilization in water, and the remaining radicals react and return to a stable state. The sterilizing power of this radical

Table 1. Redox potential of oxidant

As can be seen from Table 1, the most oxidizing substance is fluorine, followed by hydroxyl radical gas and liquid state. Ozone and chlorine, in other words, are closely related to bactericidal power in terms of oxidation potential, and this oxidative power destroys and sterilizes cell walls of bacteria.

Here will be described a little more about the sterilization mechanism of OH ^- radical.

The sterilization mechanism caused by chlorine sterilization, which is currently performed a lot, is killed when chlorine (Cl ₂ ) penetrates the cell walls of bacteria and oxygen is damaged. In addition, there is also the sterilization of antibiotics of the rock-top system, which is typical of methicillin. However, this antibiotic is bound to the active site of synaptic synth and stops the synaptic wall synthesis.

In addition, ozone sterilization is similar to radical sterilization mechanism and structurally destroys bacteria. That is, radicals destroy the cell walls of bacteria or decompose by strong oxidative force, resulting in loss of oxygen activity and inactivation of nucleic acids. So-called multi-point attacks are possible.

Since the main reaction form of ozone radicals in the neutral region is the same as that of molecular radicals, reactions with lipids, which are components of bacterial cell walls and cell membranes, occur. First, radicals react with unsaturated bonds and there is the production of the resulting peroxide free radicals, thus the chain reaction begins. At the same time, the reaction also occurs to proteins that are components of bacterial cell walls and membranes. Considering the reaction between radicals and proteins specifically refers to the reaction of radical reverse reactivity with amino acid residues, i.e., when the radical load is high, the reverse reactive functional group Reacts by breaking into it. Guanine and chimine are particularly reactive. As such, the mechanism of radical microbial sterilization is completely different from the mechanism of chlorine.

The following table shows the relationship between the chlorine and radical sterilizing power compared to the concentration. Chlorine increases the sterilization power as the concentration increases, but in the case of radicals, the effect does not appear well up to a certain concentration, but when the concentration is higher, the sterilization effect is increased.

In summary, in the case of bacteria and fungi, the first action of radicals becomes a constituent of the cell surface layer, and the deactivation of radicals by degrading proteins of bacterial membranes and cell wall components and oxidation of unsaturated fatty acid residues. It becomes a sterilization apparatus. Radial inactivation of viruses is mainly due to damage to RNA or DNA breakdown protein codes.

In particular, radicals naturally decompose rapidly in water and return to oxygen or water, but the decomposition rate varies depending on the water temperature, PH and the presence of impurities, but the half-life is within a few seconds at room temperature and atmospheric pressure. In addition, sterilization by radicals may increase consumption due to chemical reactions, which may increase the sterilization effect. However, when the radical is constant, the contact efficiency between the radical and the microorganism becomes a problem. In addition, the higher the radical solubility, the higher the sterilization efficiency at the lower temperature in the usual experiment. In more detail with respect to the present invention using the sterilization by radicals, since the water purification amount of the membrane is very small in the water purifier mainly using the membrane, the production of water is also very small. For this reason, it is necessary to have a tank to produce and store water for a long time. However, although there is also a water purifier to store water without using a membrane, the present invention is a method for sterilizing bacteria in the water tank of the reverse osmosis water purifier using the membrane, which is the majority of metal ions are removed to the membrane as it passes through the membrane Quiet water removes significant amounts of electrically conductive metal ions, and the conductivity is quite low. Therefore, the power supply of the electric circuit designed to satisfy these conditions must be designed accordingly. It must be designed as a circuit for sufficient power supply because of its low electrical conductivity. However, as a circuit for this purpose only, if a high concentration of electrolyte is introduced, the electrode reaction is violently causing problems. It generates heat and breaks, deposits residues in water, or heat generation damage of circuit components due to excessive current flow. Therefore, it is necessary to separate circuit and structural design for membrane device and water purifier. It is necessary but can be applied to either side.

In general, in water passing through the membrane, the electrode reaction is appropriate at a condition of 5 mA or more at approximately 250V. Of course it is possible to use a lower method, but it is suitable in terms of achieving sufficient sterilization efficiency and not affecting the circuit. Here, the role of the original membrane is known to completely remove metal ions, bacteria and other impurities in the water, but the experiment for the present invention confirmed that approximately 80% of metal ions were removed, so the circuit for power supply should be designed accordingly. .

FIG. 12 is a block diagram for power supply according to the present invention, in which a circuit for power supply can be seen, and FIG. 11 is a schematic diagram for explaining the principle of electrode reaction generated at both electrodes in the sterilization tank of the present invention. .

At this time, the HO gases generated a space where the gas is stored in the surface top of the tank in the hydrogen gas and the positive electrode (Anode) generated in eumgeum (Cathode) are well involved in the disinfection in the space, and the reaction is H ⁺ and the gas after The state of OH ⁻ reacts and is reduced to H ₂ O as shown in the following equation, which does not cause any obstacles or problems.

_{^{4OH - + 4H + → 4H 2}} O

At this time, due to the electrical energy applied to the cathode and the anode, a reduction reaction occurs in the cathode as shown in FIG. 7, and metal ions such as Ca ²⁺ , Mg ²⁺ , and K ^{2+ that} are positive ions are electrons. by cane is attached to the electrode during the deposition of a metal can and a hydrogen gas is generated in the hydroxyl ion (OH ^-) is increased as the following expression. (4HO → 2H ₂ O + O ₂ ↑)

In addition, the bacteria in the water in the tank is a reaction reaction of the ions according to the transfer of electrons as shown in Figure 8 by the electrode reaction caused by the cathode and the anode installed in the tank. At this time, the (+) ion moves toward the (-) electrode and the (-) ion moves toward the (+) electrode. At this time, the oligodynamic effect is caused by the movement of the ions, thereby promoting the bactericidal and suppressing effect of bacteria. do.

In addition, the present invention provides a very scientific, hygienic and accurate method for sterilizing bacteria by the oxidation of hydrogen gas, oxygen gas and OH radicals generated by the electrode reaction, in particular when the electrode reaction occurs Secondary contamination may be caused by oxidation, but this can be solved by the material of a well-selected electrode, which has the advantage that no disturbing contamination is left in the water.

However, this reaction may cause a problem of deteriorating the reliability of the electrode when used for a long time due to the adhesion phenomenon due to the electrostatic force of the ions generated by the electrical energy applied to the electrode, but it is shown in FIG. 6 and FIG. According to the principle of self cleaning, the current polarity supplied to the electrode installed in the water tank is exchanged and applied by the circuit at regular intervals, so that the metal ions attached to the water due to the phenomenon of repulsion between the positive poles of the ions are The advantage is that it releases again and increases the dynamic effect, and the electrode is designed for continuous use without long maintenance.

12 is a block diagram for power supply according to the present invention.

The present invention is a high temperature overcurrent flow that can be caused by the inflow of a material that contains a large amount of water or salt or other metal ions introduced by mistake, or water that does not pass through the membrane introduced into the tank by mistake or other causes during use In order to solve the other problem of the loss of parts, the power supply is cut off by the circuit shown in FIG. It can be designed so that there is no problem by cutting off the power supply circuit.

However, if water is stored in the tank, all the circuits will operate normally. If this happens, the user may put his hand in the middle of applying electricity even if the user touches a substance that may cause electric shock. It was confirmed that there is no. This is because first, the current is low and water flows through the water as a conductor.

On the other hand, in the water purifier sterilization apparatus of the present invention, the tap water supplied from the water pipe as shown in the 3 (a) and 3 (b) is a micro filter (11) to remove the primary suspended solids and sand and other solids. ), And the water pressurized by the pressure pump 22 is sent to the first carbon filter 10 again.

At this time, the first carbon filter 10 removes most of the taste, chromatic chlorine and other toxic organic substances which are not removed from the micro filter 11, and sends relatively clean water to the reverse osmosis membrane filter (R / O membrane) 9. The reverse osmosis membrane filter 9 removes heavy metals and other metal ions that are not removed from the first carbon filter 10, and fine organic and inorganic materials such as bacteria. The water treated as described above is passed to the water storage tank, that is, the sterilization tank 3 and stored after passing through the second carbon filter 7.8 for the second more reliable treatment.

At this time, in the present invention, the conventional UV sterilization filter 45 is installed to be sterilized by electrolysis while being stored in the water storage sterilization reaction tank 3 without being installed.

That is, when water is introduced into and stored in the water storage sterilization reaction tank 3, the sensor detects the presence of water, and if there is water, the conductivity of the water is detected by the microcomputer by the electrode itself. At this time, by checking the resistance value of water according to the conductivity of water by the microcomputer, the microcomputer checks whether the water flows through the membrane or whether the impurities (salt, etc.) do not flow. Power is supplied to (1, 4), respectively, so that an electrode reaction, that is, an oxidation reaction (anode) and a reduction reaction (cathode) occurs. Increases radical ^ion by the electrode reaction in the positive electrode as in the FIG. 11 is an oxygen gas (O ₂₎ occurs and therefore can during OH.

At this time, the positive ions and the negative ions present in the water move toward the opposite electrodes as shown by arrows 53 and 54, and precipitate at the cathode and adhere to the surface of the electrode 4. At this time, the cathode generates hydrogen gas (H ₂ ). In this way, hydrogen gas and oxygen gas generated between water, i.e., the positive electrode (1,4), are combined to form hydrogen peroxide (H ₂ O ₂ ) or radicals (OH, O etc) to react in water to sterilize bacteria. Some come out of the air in the tank and sterilize the air in the tank.

At this time, the radicals with high oxidative power generated by the electrode reaction have a very fast reaction time, so that they are reduced to water (H ₂ O) or oxygen (O ₂ ) in a stable state without any problem after the reaction. It's a very hygienic and simple device that leaves no problems in the air.

On the other hand, when the device of the present invention is applied to the electrode for a long time and the same polarity voltage is solved the problem that the metal precipitates and adheres to the electrode, and can achieve the purpose of sterilization of bacteria by the oligodynamic effect In order to generate the effect of two stones, the polarity of the voltage is alternately flowed to the electrode at regular intervals, and the ion is released or adsorbed to the electrode to repeat the effect of sterilization by the oligodynamic effect of the metal ion. In addition, the problem of efficiency decrease due to the metal ions deposited and attached to the electrode can be automatically solved.
