It relates to a high odor treatment device using the same.

Generally speaking, odor is a odor that stimulates the nervous system of a person and causes mental and physical damage. These odor causing substances vary greatly depending on the source, and sewage treatment plants, incinerators, food waste treatment facilities, landfills, oil refineries, chemical plants, manure and livestock wastewater treatment plants are considered to be major sources of odor in the city.

Odors generated from odor generating facilities are caused by decaying substances or various volatile organic compounds, which not only cause discomfort, but are also harmful to the human body and have many problems, such as deterioration of efficiency or increased safety accidents due to reduced concentration. do.

Ammonia, methylmercaptan, hydrogen sulfide, methyl sulfide, methyl disulfide, trimethylamine, acetaldehyde, styrene and the like are regulated as legally regulated substances as such odor components. Odor substances may be divided into basic, acidic and neutral systems depending on pH. For example, ammonia and trimethylamine belong to the basic system, hydrogen sulfide, methyl mercaptan, propionic acid, normal butyric acid, and isovaleric acid belong to the acid system, and methyl sulfide, methyl disulfide, acetaldehyde, etc. Belong.

Conventional methods for removing such odor components are largely classified into physical, chemical and biological treatment methods. Currently used methods include combustion, cleaning, oxidation, adsorption, and microbial treatment.

Combustion method is effective to remove almost all combustible odorous substances, but it is expensive to maintain fuel or catalyst, and there is a risk of nitrogen oxide and explosion if it is neglected in operation management.

In addition, the washing method is a method in which the malodorous gas is washed with water, an acid or an aqueous alkali solution and deodorized. This method has the advantages of relatively simple equipment and low operating cost, but it has a narrow application range, difficult treatment of complex odor, and measures to prevent corrosion of facilities by using chemical solution, and wastewater, which is a secondary pollution source, is generated. There is this.

In addition, the oxidation method is a method of oxidizing and removing odor components by utilizing the powerful oxidation of ozone, which is relatively efficient in removing a large amount of gas due to low power consumption and easy maintenance, but ozone alone has a small application range and insufficient performance. There are disadvantages.

Adsorption method is to remove odor by using activated carbon.In the pores of activated carbon, various odorous substances are accumulated and adsorbed in saturation state.Therefore, there is no deodorizing effect. When the concentration of the target material is high, there is a disadvantage in that the concentration of the pretreatment such as washing, absorption, cooling, and condensation is reduced in parallel, followed by activated carbon adsorption.

Microbial treatment is a method of decomposing odorous substances adsorbed using microorganisms when odors pass through wood chips or soil. When the growth conditions of microorganisms are properly formed, the ability to remove odors is excellent and secondary pollutants are generated. On the other hand, it takes up a lot of area and takes a lot of time.

The photocatalytic reaction means includes an ultraviolet lamp 79 installed inside the branch tube 70 and a gas flowing into the flow path that is installed inside the branch tube 70 and spirally surrounds the ultraviolet lamp 79. And a vortex induction member 75 for guiding the vortices to a vortex, and a spin cell 73 disposed inside the branch tube to surround the vortex induction member.

The ultraviolet lamp 79 is installed in the quartz tube 77 and is installed at the center of the branch tube 70. The lower and upper ends of the quartz tube 77 are supported by the first holder 100 installed in the gas inlet case 51 and the second holder (not shown) installed in the gas outlet case 60. The first holder 100 may be coupled to the gas inlet case 51 to penetrate the bottom surface of the gas inlet case 51. Although not shown, the second holder may be coupled to the gas outlet case 60 to penetrate the upper surface of the gas outlet case 60. In this case, the second holder has the same configuration as the first holder 100 and only the installation position is different.

The vortex induction member 75 guides the flow of gas introduced into the flow path of the branch tube 70 into the vortex to extend the residence time in the branch tube 70. The vortex guide member 75 is installed between the quartz tube 77 and the branch tube 70 in which the ultraviolet lamp 79 is built. The vortex induction member 75 is formed to spirally surround the quartz tube 77. The cross section of the vortex guiding member 75 is formed in a thin plate shape with a constant width. The lower end of the vortex guiding member 75 extends through the opened lower portion of the branch tube 70 to the bottom of the gas inlet case 51.

The upper end of the vortex induction member 75 also extends through the open upper portion of the branch tube 70 to the upper surface of the gas outlet case 60 and is fixed to the second holder.

When the gas introduced into the gas inlet case 51 flows into each branch tube 70, the branch tube 70 passes through the branch tube 70 while rotating helically around the quartz tube 77 by the vortex guide member 75. The residence time is extended.

A cylindrical spin cell 73 is further installed inside the branch tube 70 together with the vortex guide member 75. The spin cell 73 is disposed inside the branch tube 70 to surround the vortex guide member 75. The lower end of the spin cell 73 passes through the opened lower part of the branch tube 70 and is supported by the bottom surface of the gas inflow case 51. The upper end of the spin cell 73 passes through the opened upper part of the branch tube 70 and is supported on the upper surface of the gas outlet case 60. The spin cell 73 has a mesh network structure that forms a plurality of meshes by crossing wires. The spin cell 73 is formed around the vortex induction member 75 to induce turbulence by contact with the flow of gas rotating along the vortex induction member 75. The spin cell 73 can further extend the residence time of the gas to increase the number of contact with the gas to improve the photolysis efficiency.

At least one surface of the branch tube 70, the vortex induction member 75, and the spin cell 73 is formed with a photocatalyst coating layer which is photoactivated by ultraviolet light emitted from the ultraviolet lamp. The photocatalyst is a substance having a strong redox capability by ultraviolet light, and examples of the photocatalyst that can be used as the photocatalyst include ZnO, CdS, WO ₃ , and TiO ₂ . Among these, titanium dioxide can be used semi-permanently without being changed even when it receives light. In addition, titanium dioxide has much stronger oxidation power than that of the excitation electrons. The energy position of the hole is about +3 V at the hydrogen reference potential, which is much higher than that of 1.36 V of chlorine (Cl ₂ ) and 2.07 V of ozone (O ₃ ), and has a strong organic decomposition ability. Therefore, it is preferable to use titanium dioxide (TiO ₂ ) as a photocatalyst. When titanium dioxide photocatalyst is irradiated with UV light, electrons and major bands are formed to produce hydroxy radical (-OH) and superoxide which have strong oxidizing power, and hydroxy radical and superoxide oxidize and decompose organic compound into water and carbon dioxide gas. Change. This principle oxidizes the volatile organic compounds in the gas and converts them into harmless water and carbon dioxide.

When the photocatalyst coating layer uses titanium dioxide, the anatase-type titanium dioxide (TiO ₂ , P-25 of Degussa) powder is dispersed in a solvent such as water or acetic acid, and the coating liquid is formed on the inner circumference of the branch tube 70.

It has a drive part. The upper surface of the rotary table 80 is formed with a circular coupling groove, the lower end of the spin cell 73 is fitted into the coupling groove. Although not shown, the upper end of the spin cell 73 in the present embodiment is extended to only the upper end of the branch tube 70, or even extended to the inside of the gas outlet case 60 is not fixed to the gas outlet case (60).

The rotary table 80 is installed inside the gas inflow case 51. The first holder 100 penetrates through the center of the rotary table 80. Therefore, the rotary table 80 rotates using the fixed first holder 100 as the center of rotation. Teeth are formed around the rotary table 80. The rotary tables 80 supporting the spin cells 73 of the branch tubes 70 are arranged to engage each other by teeth. Therefore, when one rotating table rotates, adjacent rotating tables rotate together.

When the drive gear 81 rotates, the rotary table 80 meshing with the drive gear rotates. Accordingly, a plurality of rotating tables engaged with each other rotate. As the spin cell 73 rotates as described above, the number of times of the gas passing through the branch tube 70 and the spin cell 73 increases, and the passage time of the gas is extended, thereby greatly improving the photolysis efficiency of the volatile organic compound. You can.
