Description

{Manufacturing equipment for hydroxyl radical containing water}

The present invention relates to a production device and operation system for hydroxyl radical-containing water. In particular, by integrating a pair of identical electrodes symmetrically in a single water electrolysis cell case, it is not only compact and simple, but also has a large capacity using electrolysis of water. It relates to a production device for hydroxyl radical-containing water that can generate hydroxyl radical (·OH radical) functional water.

Hydroxyl radical (·OH) is an oxyanionic substance created by dissolving ozone or hydrogen peroxide in water or by decomposition of oxygen and water molecules in the air by irradiating ultraviolet or visible light on the surface of the photocatalyst. It is an oxyanionic substance that destroys almost all pollutants. It is a natural substance that is harmless to the human body and has the strongest sterilizing effect by being involved in sterilization and disinfection and can chemically oxidize and decompose organic and inorganic substances.

Among existing substances, the oxidizing power of hydroxyl radical is second only to fluorine (F) and is stronger than ozone or chlorine, but it is not a harmful substance that is toxic to the human body like fluorine, chlorine, and ozone. The characteristics of the hydroxyl radical are that it has a strong sterilizing power, has the ability to decompose and remove all heavy metals and chemical components, and directly participates in pollutants in the air and water, providing healthy water rich in dissolved oxygen.

Therefore, the use of hydroxyl radicals is to create a clean environment by effectively sterilizing and deodorizing almost all disease germs, such as various spoilage bacteria, food poisoning bacteria, mold (fungus), bacteria and viruses, within 5 to 10 seconds.

In particular, as a method of using hydroxyl radicals to purify water, a method of electrolyzing water to generate ozone and hydrogen peroxide and decomposing them again to produce hydroxyl radicals is adopted.

Patent Documents 1 and 2 describe the manufacturing and method of a device for generating electrolyzed water (·OH-containing water) with strong sterilizing power by electrolyzing the above-mentioned water.

The content of the above-mentioned patents is almost similar, and there are differences in the materials that make up the electrolytic cell, electrode placement, electrolysis method, etc., and only distinguish between methods to maximize the efficiency.

Patent Document 1 describes an ion exchange unit configured to bring tap water into contact with the chlorine ion exchange resin using a chlorine-type anion exchange resin, and a method of generating hydroxyl radicals by electrolyzing the water flowing through this ion exchange unit, which contains hydroxyl radicals. This is a method of containing less than about 1 ppm of chlorine in water.

Patent Document 2 is a device that uses a plate-shaped metal mesh catalyst electrode as an electrode for electrolysis of water and forms a contact surface between the two electrodes with a solid electrolyte membrane in close contact to perform electrolysis of water and has a catalyst layer that reduces or increases oxygen overvoltage. If the electrolyte membrane is in close contact with the two electrode surfaces and a high voltage or current is passed, there is a risk that the electrolyte membrane will deteriorate quickly.

Therefore, there is an urgent need for the development of a device and operating system that are more efficient, easier to operate, compact and small, and do not contain chlorine ions and can maximize the amount of hydroxyl radicals produced.

It is a schematic diagram of the water electrolysis cell case of the apparatus for generating and manufacturing hydroxyl radical-containing water, and Figure 4a is a schematic diagram showing the combined state of the water electrolysis cell case and the second electrode cover of the apparatus for generating and manufacturing hydroxyl radical-containing water according to the present invention. , FIGS. 4B and 4C are schematic diagrams of the first electrode cover and the second electrode cover of the apparatus for producing hydroxyl radical-containing water according to the present invention, and FIGS. 5A to 5C are schematic diagrams of the hydroxyl radical-containing water according to the present invention. These are drawings showing the raw material water flow path and electrolyte flow path of the production and manufacturing equipment.

As shown in Figures 1 to 3, the apparatus for generating and manufacturing hydroxyl radical-containing water according to the present invention is in the form of a square frame, and the upper left and right sides are in a zigzag shape formed on the left and right by injecting the electrolyte supplied from the electrolyte supply unit. An electrolyte inlet 11 and an electrolyte outlet 12 are formed to discharge the electrolyte along the electrolyte flow path, and the raw material water supplied from the raw material water supply unit is injected adjacent to the electrolyte inlet 11 and the electrolyte outlet 12. A water electrolysis cell case 10 in which a raw water inlet 13 and a raw water outlet 14 are formed, respectively, to be discharged along a coil-shaped raw water flow path formed on the left and right to surround a zigzag-shaped electrolyte flow path; A first electrode portion 20 in which a first anode 21 and a first cathode 22 are arranged back and forth on the front of the rectangular frame-shaped water electrolysis cell case 10 and accommodated therein; And a second electrode unit 30 in which a second cathode 31 and a second anode 32 are disposed back and forth on the rear side of the rectangular frame-shaped water electrolysis cell case 10 to receive the electrolyte solution. The electrolyte solution, which is discharged along the zigzag-shaped electrolyte flow path between the inlet 11 and the electrolyte outlet 12, flows while contacting between the first cathode 22 and the second cathode 31, and the raw material water The raw material water discharged along the upper and lower coil-shaped raw material water flow path between the inlet 13 and the raw material water outlet 14 is electrolyzed by flowing while contacting the first anode 21 and the second anode 32. This causes hydroxyl radicals to be generated in the raw water flowing along the upper and lower coil-shaped raw water flow path.

As shown in FIG. 3, the water electrolysis cell case 10 is preferably made entirely of plastic in the form of a square frame.

That is, the electrolyte inlet 11 and the electrolyte outlet 12 are arranged in a balanced manner on the upper left and right sides of the water electrolyte cell case 10 to receive and discharge the electrolyte from an external electrolyte supply unit (not shown). In the illustrated example, the electrolyte inlet 11 is disposed on the right and the electrolyte outlet 12 is disposed on the left, but they may be installed in opposite directions.

The electrolyte solution is adjusted to have a chlorine ion concentration between 10 and 100 mg/l. When the chlorine ion concentration is high, oxidation degradation on the anode (+) side is suppressed and current efficiency is maintained high.

Here, the electrolyte solution, which is cathode water discharged through the electrolyte discharge port 12, is preferably used by adjusting the concentration of the electrolyte aqueous solution and recirculating it using a micro pump.

The raw material water inlet 13 and the raw material water outlet 14 are arranged in a balanced manner on the upper side adjacent to the electrolyte inlet 11 and the electrolyte outlet 12 located on the upper left and right sides of the water electrolysis cell case 10, Raw material water (tap water) is supplied from the raw material water supply unit (not shown), and as shown in FIGS. 5A to 5C, which will be described later, hydrolysis is added to the raw water flowing along the raw material water flow path in the upper and lower coil form by electrolysis. Hydroxyl radical-containing water that generates roxyl radicals is discharged and stored externally.

At this time, it is desirable to adjust the temperature of the raw material water (tap water), which is the supplied anode water, to be maintained at about 10 to 20°C. If the temperature is too high, there is a risk that ozone in the anode water will be ejected as gas and the amount of hydroxyl radical-containing water produced will be reduced.

In addition, of course, not only tap water but also pure water, distilled water, reverse osmosis purified water, etc. can be used as raw water.

Meanwhile, as shown in FIG. 3, a square-shaped stainless steel cathode terminal 40 is placed in close contact with the square-shaped hollow portion inside the center of the square-frame-shaped electrolytic cell case 10, and the square On the upper and lower inner surfaces of the frame-shaped stainless steel cathode terminal 40, a plurality of electrolyte flow guide rods 41 form a flow path space (one electrolyte flow guide bar forms a flow path space by preventing the end of the electrolyte flow guide bar from touching the lower or upper side). ) are formed in alternating order to form a zigzag-shaped electrolyte flow path, so that the electrolyte flowing in from the electrolyte inlet 11 flows along the zigzag-shaped electrolyte flow path and is discharged to the electrolyte outlet 12 (Figure see 5a).

In addition, the exterior of the square frame-shaped water electrolysis cell case 10 is formed to be thicker than the thickness of the square frame-shaped stainless steel cathode terminal 40, but the upper and lower sides are spaced left and right to guide a plurality of raw material water flows. A hole 42 is formed.

An unexplained symbol 43 is a power supply terminal for supplying power to the stainless steel cathode terminal 40, and is protected by a power protection cover 44.

In addition, between the area of the square frame-shaped stainless steel cathode terminal 40 and the area where the plurality of raw material water flow path guide holes 42 are formed, the positive terminal 50 of the first and second electrode portions is formed in the form of two opposing square frames. , 51) are coupled through a coupling means (e.g., a rivet) to supply power to the first and second anodes.

As shown in FIG. 2, etc., the first electrode unit 20 has a first anode 21 and a first cathode 22 sequentially arranged back and forth on the front of the rectangular frame-shaped water electrolysis cell case 10. is formed, and a first anode terminal 50 is disposed on the front of the first positive root.

As shown in FIG. 2, etc., the second electrode unit 30 has a second cathode 31 and a second anode 32 arranged sequentially back and forth on the rear of the rectangular frame-shaped water electrolysis cell case 10. A second anode terminal 51 is disposed on the back of the second anode and electrically connected to the second anode.

Of course, as described above, the square-shaped hollow portion inside the center of the square-frame-shaped water electrolysis cell case 10 is closely disposed with the square-frame-shaped stainless steel cathode terminal 40 to form the first cathode 22 and the second cathode 22. 2 is electrically connected to the cathode (31).

Accordingly, the first electrode portion 20 and the second electrode portion 30 are manufactured integrally with substantially the same configuration in a symmetrical form at the front and rear of the rectangular frame-shaped water electrolytic cell case 10.

The first electrode unit 20 includes a mesh-shaped first anode 21 disposed behind the front first anode terminal 50, a first polymer electrolyte membrane 23 as a solid ion exchange membrane, and a first non-conductive membrane. A filter 24 and a mesh-shaped first cathode 22 are sequentially formed and installed in close contact with the front of the water electrolysis cell case 10, and the second electrode unit 30 is a mesh-shaped second electrode 22. A cathode 31, a second non-conductive filter 33, a second polymer electrolyte membrane 34 as a solid ion exchange membrane, and a mesh-shaped second anode 32 are sequentially formed to form the water electrolysis cell case 10. is installed in close contact with the front, and the second anode terminal 51 is disposed behind the second anode, and the cathode (on both sides with respect to the cathode terminal 40) is formed in the center of the electrolysis cell case 10. The first and second electrode parts 20 and 30 are installed in an integrated form.

Here, between the first electrode unit 20 and the second electrode unit 30, that is, the first cathode 22 and the second cathode 31, are spaced at a certain distance (3 to 3) in the center of the electrolysis cell case 10. It is installed with a gap of 5 mm) between the first anode 21 and the second anode 32, anode water (tap water as raw material), and an electrolyte solution (aqueous electrolyte solution) between the first cathode 22 and the second cathode 31. ) is distributed, and the positive electrodes (21, 32) and negative electrodes (22, 31) of the first and second electrode parts are connected to the two positive terminals (50, 51) and one negative terminal (40) in contact with each other. Electrolysis reaction of water is performed by applying direct current power.

At this time, the direct current power is preferably 4 to 24 Volts and 10 to 50 A/cm2, with a minimum of 40 Watts and a maximum of about 1 k Watt.

Characteristics such as materials of the first electrode portion 20 and the second electrode portion 30 will be described in more detail.

The material of the anodes 21 and 32 and the cathodes 22 and 31 is platinum or titanium plated with platinum. The mesh wire diameter is about 0.3 to 0.8 mm and the number of holes is about 40 to 80 mesh. desirable.

If it is smaller than 40 mesh, that is, if the hole size is large, turbulence in the anode water does not occur and the contact time of the anode water with the anode tends to be shortened. If it is larger than 80 mesh, the flow of anode water is slowed or impurities are removed. There is concern that intervention may cause problems with water flow being interrupted.

It is desirable to install the cathodes 22 and 31 so that they do not come into direct contact with the polymer electrolyte membranes 23 and 34. As the gap becomes larger, deterioration of the electrolyte membrane decreases, but power loss tends to increase. The gap distance is preferably a distance that generates a potential difference of about 1/10 to 4 times the potential difference between the two electrodes.

When used as a platinum plating electrode, if electrolysis proceeds for a long time, platinum is precipitated as an oxide layer on the surface of the anode, and this platinum oxide is adsorbed on the solid electrolyte membrane as it heads to the cathode, deteriorating the electrolyte membrane and causing damage. This causes a problem. It is desirable to install a quartz or glass fiber filter as a non-conductive filter (24, 34) between the electrolyte.

In addition, the polymer electrolyte membranes 23 and 34 are installed between the anode (+) and the cathode (-), one side of the electrolyte membrane is installed in close contact with the anode (+) side, and the polymer electrolyte membrane (23, 34) is installed at a distance of 0.1 to 0.8 mm from the cathode (-). Install with a gap. This void is filled with a dielectric or porous non-conductive membrane (quartz or fiberglass filter). The solid electrolyte membrane uses a sulfonic acid-type cation exchange resin as a proton conductive membrane. As a commercially available product, Nafion membrane (product of DuPont) can be used, but a similar cation exchange membrane can be used without being limited thereto. Generally, the thickness of the solid electrolyte membrane is 0.05 to 0.5 mm. It is desirable that the solid electrolyte membrane is installed so that ions or electrons can be exchanged, and that the conductivity of the solid electrolyte membrane is approximately the same as the conductivity of the aqueous electrolyte solution in the cathode (-) portion.

On the other hand, when using a platinum-plated titanium mesh electrode, which is almost the same material as the anode (+), as the cathode (-) material, a porous body, network, etc. with a pore surface like the anode (+) is used to release hydrogen gas during electrolysis. By having a structure of , hydrogen gas escapes or dissolves in the electrolyte solution. It is desirable to install the cathode (-) so that it does not come into direct contact with the solid electrolyte membrane. As the gap becomes larger, deterioration of the electrolyte membrane decreases, but power loss tends to increase. The gap distance is preferably a distance that creates a potential difference of about 1/10 to 4 times the potential difference between the (+) and (-) poles.

Meanwhile, as shown in FIGS. 1 and 2 and FIGS. 4A to 4C, the above-described first electrode portion 20 and the second electrode portion 30 are located before and after the rectangular frame-shaped water electrolysis cell case 10. ) are integrated front and back, and the first and second electrode covers 60 and 70 in the form of caps are opposed to each other to cover the front and back and are coupled through a coupling means such as a rivet.

At this time, on the inside of the opposing first and second electrode covers, a first anode 21 (first anode terminal) and a second anode 32 (second anode terminal) are coupled back and forth to the electrolysis cell case when combined. In contact with the raw material water flow grooves 61 and 71, which are inclined diagonally up and down at regular intervals on the left and right, are formed to face each other (see FIGS. 4A to 4C).

Meanwhile, as described above, each of the raw material water flow path guide holes ( 42) is installed to communicate at the upper and lower ends of a plurality of diagonally inclined raw water flow grooves 61 and 71, so that the raw water flowing in through the raw water inlet 13 flows into the first and second electrode covers. The zigzag-shaped electrolyte is allowed to flow naturally and sequentially along the raw material water flow grooves 61 and 71 formed on the inside of the water electrolysis cell case 10 and the flow guide holes 42 formed on the left and right sides of the water electrolysis cell case 10. Surrounding the flow path, a raw material water flow path in the form of an upper and lower coil (each alternating in a winding shape) is automatically formed, allowing the raw material water to circulate while contacting the first anode 21 and the second anode 32. Hydroxyl radicals are generated in raw water through electrolysis and can be discharged to the outside (see FIGS. 5A to 5C).

According to the following electrode reaction for electrolysis of water when higher power (voltage and current) than that applied to the electrolysis of water to produce oxygen and hydrogen is used by the device for generating and producing hydroxyl radical-containing water according to the present invention. It can be seen that water rich in hydroxyl radical content is generated at the anode (+).

The ozone production reaction by electrolysis of water is as follows.

1) Anode reaction

2H ₂ O → O ₂ + 4H ⁺ + 4e ^- E°1.229V-------①

3H ₂ O → O ₃ + 6H ⁺ + 6e ^- E°1.511V--------②

O ₂ +H ₂ O → O ₃ + 2H ⁺ + 2e ^- E°2.075V--------③

2)Cathode reaction

2H ⁺ +2e ^- → H2 E°0V---------④

3) Hydroxyl radical generation reaction

Ozone generated in the anode (+) reaction goes through the following reaction formulas ⑤, ⑥, and ⑦ to generate hydroxyl radicals (·OH), oxygen, and hydrogen dioxide. For reactions ⑤, ⑥, and ⑦, the reaction constant value (k) is about 10 ⁷ M ^-1 S ^-1 or more, so the reaction proceeds quickly to the right, and hydroxyl radical (·OH) is finally generated as shown in reaction formula ⑧. do.

O ₃ + OH ^- → HO ₂ ^- + O ₂ ---------⑤

O ₃ + HO ₂ ^- → O ₃ ^- + HO ₂ ---------⑥

O ₃ - + H ₂ O → ·OH + O ₂ + OH ^- ---⑦

⑤+⑥+⑦

2O ₃ + H ₂ O → ·OH +2O ₂ + HO ₂ ---⑧

The ozone generation reaction includes the six-atom reaction equation ②, in which ozone is created directly from water molecules, and reaction equations ① and ③, in which oxygen is first generated from water molecules, and this oxygen changes into ozone.

It is preferable to perform electrolysis of water through the electronic reactions in Reaction Formulas ① and ③ above because it can increase current efficiency, and oxygen radicals such as ·OH, 2O ₂ , and HO ₂ are generated as in Reaction Formula ⑧.

Hydrogen gas or hydrogen radicals are generated at the cathode (-), and the hydrogen gas is discharged to the outside.

Meanwhile, for power supply by direct current power, a voltage of 4 to 20 V and a current density per unit of 0.1 to 5.0 A/cm2 are desirable, and it can be seen that it is easy to generate ozone or active oxygen within this range. If the current density is too high, the temperature of the anode water increases, promoting the movement of ozone from the liquid phase to the gas phase, which tends to lower the concentration of ozone water.
