In addition, in the water tank 110, an overflow pipe 170 is installed in the upper portion so that water overflowing from the water tank can be discharged, and a drain hole 180 is installed in the lower portion to drain water.

In addition, it is preferable that a demister 190 is installed on the upper part of the scrubber body 100 so that a large amount of water vapor contained in the exhaust gas can be recovered as water.

The first filter unit 210 and the second filter unit 220 are installed in the scrubber body 100 in two stages from the lower side to the upper side. Here, the first filter unit 210 and the second filter unit 220 are filled with a plurality of carriers (media), and the odor gas contained in the harmful gas is filtered by the carrier and together with water. It flows down.

The first injection port 310 and the second injection port 320 are respectively installed above the first filter unit 210 and the second filter unit 220 to spray water. That is, the first injection port 310 is installed in the first sprinkling pipe 311 and the first sprinkling pipe 311 receiving water from the water tank 110 through a circulation pump 400 to be described later, Consisting of a first injection nozzle 312 for spraying water from the top of 210, the second injection port 320 is a second spraying water receiving plasma gas together with water from a wet plasma supply means 500 to be described later. It consists of a second spray nozzle 322 installed in the pipe 321 and the second sprinkling pipe 321 and spraying the plasma gas with water from the upper side of the second filtering part 220.

The circulation pump 400 is configured to circulate and supply the water contained in the water tank 110 to the first injection port 310 through a circulation pipe 410. That is, the circulation pump 400 is configured to recirculate and supply the water contained in the water tank 110 to the first injection port 210 by connecting the water tank 110 and the first injection port 210 through a circulation pipe 410 do.

The wet plasma supply means 500 is connected to the second injection port 320 and is configured to supply a plasma gas together with water to inject through the second injection port 320.

Here, the wet plasma supply means 500 includes an underwater low-temperature plasma generator 510, a storage tank 520 that converts water stored by the generated low-temperature plasma into sterilization water, and sterilization water in the storage tank 520 It consists of a supply pipe (P3) for supplying the second injection port (320).

At this time, an air supply pipe (P1) is connected to the underwater low-temperature plasma generator 510 to supply oxygen or air to facilitate oxygen supply, and introduced from the water supply pipe 20 to the storage tank 520 The old water supply pipe (P2) is connected. In addition, the supply pipe P3 connected to the second injection port 320 is branchly connected to the water supply pipe P2 so that water can be sprayed through the second injection port 210.

In addition, a drain pipe 530 is connected to the bottom surface of the storage tank 520, and the end of the drain pipe 530 is connected to the supply pipe P3 in a venturi type or orifice form to drain through the drain pipe 530 It is configured so that the sterilized water inside the storage tank 520 can be sucked and discharged by the drain pressure. In other words, it is possible to sprinkle sterilizing water naturally in a non-powered manner without having a separate driving pump by using the water pressure of the water supply pipe 20.

More specifically, a part of the water withdrawn from the water supply pipe 20 is injected and stored in the water storage tank 520 through the water supply pipe (P2), and when it reaches a certain level, water is automatically watered by a water level regulator such as a well-known float. The supply is cut off. In addition, some water is moved toward the second sprinkling pipe 321 of the second sprinkler by riding the supply pipe P3 branched from the water supply pipe P2, and at this time, a part of the water inside the storage tank 520 is transferred to the supply pipe P3. ), while being sucked by the water pressure flowing along the water, it moves to the second sprinkling pipe 321 while being mixed to be sprayed.

However, at this time, since the water stored in the storage tank 520 is changed into sterilized water by the plasma treatment that operates periodically, this sterilizing water having a plurality of radicals is sprayed through the second sprinkling pipe 321 to sterilize and odor. It will perform the removal function.

On the other hand, the underwater low-temperature plasma generator 510 is configured by combining a plurality of water storage tanks 520, as shown in Figures 4 and 5; The constant underwater low-temperature plasma generator 510 includes a cylindrical positive electrode fixing cylinder 511, a negative electrode connecting cylinder 512 extending with a smaller diameter from the lower end of the positive electrode fixing cylinder 511, and the positive electrode fixing cylinder ( An air inlet port 513 formed on a part of the outer circumferential surface of the 511 to receive air from the air supply pipe P1, and the negative electrode connection tube 512 is screwed inside and the upper and lower ends are opened, and the negative power is connected. It includes a negative electrode 515 and a positive electrode 314 extending through the positive electrode fixing tube 511 to an inner lower end of the negative electrode 515 and to which a positive power source is connected.

At this time, it is preferable that the upper surface of the positive electrode fixing cylinder 511 is sealed, and the positive electrode 514 is installed so as to penetrate therethrough, which allows air or oxygen supplied through the air inlet port 513 to pass through the positive electrode fixing cylinder 511 ) It is to make it flow smoothly toward the negative electrode 515 from the inside. That is, it is to increase the plasma generation efficiency through this.

In addition, the negative electrode 515 has a cylindrical shape with open upper and lower ends, and a connection screw part 516 is formed at the upper end to be screwed to the negative electrode connection container 512, and a plurality of discharge holes 517 are formed on the circumferential surface. It is particularly preferable that the plasma is formed so that the generated plasma can be smoothly discharged while increasing the plasma generation efficiency.

Here, the underwater low-temperature plasma is a plasma sterilization effect by discharging electric current in low-temperature water. Water molecules are bundled with various kinds of radicals including hydrogen ions, oxygen ions, and hydroxyl radicals by the low-voltage low-temperature plasma caused by underwater discharge. In particular, hydroxyl radicals have a strong disinfecting effect and odor removal effect, and the changed sterilization water is immediately sprayed and supplied to a pollutant source to increase odor removal and sterilization and disinfection effects. And, since it is reduced to water after a certain period of time, it is possible to implement a safe and eco-friendly sterilization and odor removal system without secondary pollution.

In addition, when plasma is generated, micro-nanobubbles generated in water continuously generate white bubbles.When the nanobubbles come into contact with contaminants, they sterilize and collect and destroy odors and fungi caused by rupture to remove odors and implement strong disinfection. I will. That is, when a voltage is applied, a low-temperature plasma is generated as a discharge occurs between the positive electrode 514 and the negative electrode 515, which decomposes water to periodically generate a number of radicals including hydrogen ions and oxygen ions.

At this time, when water flows into the supply pipe (P3), the sterilized water is discharged through the drain pipe (530), and the discharged sterilizing water moves along the second sprinkling pipe (321) along with the water flowing through the branch pipe (P3) to perform a second filtration. By spraying through the second injection nozzle 322 from the upper side of the part 220, the odor removal and sterilization functions are performed. Therefore, it is not necessary to spray and manage chemicals every time as in the past, and there is a special advantage that can eliminate problems such as non-eco-friendly and risk factors caused by chemical treatment.

In addition, in the present invention, a mesh body in which a plurality of elution balls are charged may be embedded in the storage tank 520 in order to increase odor removal performance.

These elution balls increase the deodorizing power of harmful ingredients and maintain the elution characteristics even at low temperatures (0-15°C), and to increase the ability to decompose odors, 3.5% by weight of manganese acetate, 5 parts by weight of hydrolyzed keratin, and 8.5 parts by weight of manganese nitrate %, 5% by weight of clay powder, 12.5% by weight of NTA (Nitrilotriacetic acid), 0.05% by weight of water-soluble iron salt, and the remaining polyurethane resin were molded into balls having a diameter of 2 cm.

At this time, manganese acetate is gradually oxidized when it is decomposed into a rhombic crystalline powder to form manganese oxide, and is added to enhance the effect of decomposing organic matter and promoting radical reaction. In addition, hydrolyzed keratin is added to increase the slip property by enclosing the powder particles in the mixture to form a film, and to enhance the characteristics of removing harmful substances.

In addition, manganese nitrate is added to increase the ability to decompose and remove organic matter and odor by expressing a photocatalytic effect in the visible light region. In addition, Terra abla refers to white clay mainly composed of kaolin and montmorillonite, but acid clay, which is a montmorillonite clay, is preferable. Because of its strong adsorption and insecticidal properties, it has excellent properties in deodorizing function. to provide.

In addition, NTA is nitrilotriacetic acid, a white crystalline powder obtained by reacting potassium cyanide and formalin to a mixture of ammonia and monochloroacetic acid, and odors such as ammonia, trimethylamine, hydrogen sulfide, and mercaptan through chelation with iron salts. It is an excellent chelating agent for removal. And, the water-soluble iron salt is any one selected from Fe(NO ₃ ) ₃ , FeCl ₃ , FeSO ₄ , and reacts with the chelating agent to directly affect hydrogen sulfide removal.

In order to check the deodorizing effect of the elution ball, the elution ball was placed in a transparent box with a size of 20 cm × 20 cm × 15 cm, filled with water about half, and ammonia was put inside the box, sealed, and the deodorizing ability was checked.

As a result, ammonia was completely trapped and decomposed within 55 minutes of the experiment.

On the other hand, in the present invention, in order to increase the reaction and effect of radicals, a coating layer may be further formed on the inner circumferential surface of the second sprinkling pipe 321 to a predetermined thickness.

The coating layer is tartaric acid 3.5% by weight, EDTA (Ethylenediaminetetraacetic acid) 10% by weight, FeSO ₄ .7H ₂ O aqueous solution 10% by weight, 2-acrylamino-2-methylpropanesulfonic acid 2.5% by weight, liquid silicone 3% by weight %, and 2.5% by weight of triclosan, and a resin composition consisting of the remaining epoxy resin is applied.

At this time, tartaric acid is added to induce chelation of iron salts and EDTA, and since EDTA has a strong affinity for metal ions, hydrogen sulfide is effectively decomposed and removed through stable chelation with iron salts.

And, FeSO ₄ .7H ₂ O aqueous solution is an iron salt, that is, a base for chelating that provides iron ions, and 2-Acrylamino-2-methyl propane sulfonic acid is liquid silicone. It is intended to increase the durability while enhancing the adhesion and deformation suppression by increasing the fixing power of the coating layer, and the liquid silicon is to maximize the adhesion fixing power of the coating layer while enhancing the water resistance and waterproofness while increasing the flexural strength.

In addition, the triclosan (trichlosane) is added to enhance antibacterial properties by inhibiting the activity of bacteria including mold as a fungicide, and the epoxy resin is a base resin for enhancing weather resistance while maintaining stable adhesion at the interface.

When the coating layer is formed in this way, due to the porosity of the epoxy resin, certain components are eluted from the chelated iron salt-EDTA in the coating layer each time the sterilizing water flows through, and the components are sprayed with the sterilized water in the contaminants, and odor substances such as ammonia including hydrogen sulfide It contributes significantly to decomposition and elimination.
