Description

Plasma Deodorizer

The present invention relates to a plasma deodorizer, and more particularly, to a plasma deodorizer for removing odor generated in wastewater or sewage treatment plants by plasma.

In general, odor is an unpleasant odor, and representative examples thereof include inorganic compounds such as hydrogen sulfide and chlorine gas, nitrogen compounds including fatty acids and amines, and organic compounds such as mercaptans and the like. Compounds and the like.

In particular, volatile organic compounds (V.O.C) is a generic term for liquid or gaseous organic compounds that have a high vapor pressure and easily evaporate into the atmosphere. It refers to a substance that causes photochemical smog by generating photochemical oxidizing substances such as ozone by causing photochemical reaction in the atmosphere.

In particular, volatile organic compounds are not only air pollutants, but also carcinogens, and are the cause of global warming. Benzene, acetylene, gasoline, and the like, and various solvents used in industry.

When volatile organic compounds coexist with nitrogen oxides in the air, photochemical reactions are generated by the action of sunlight to generate photochemical oxidizing substances such as ozone and pan (PAN: peroxyacetyl nitrate), and they refer to all substances that cause photochemical smog. . It is an air pollutant and a carcinogenic toxic chemical and a precursor to photochemical oxides. It is also a source of global warming and can cause odors.

At this time, Article 39 (1) of the Enforcement Decree of the Korean Air Environment Conservation Act is defined as petrochemical products, organic solvents or other substances, and 31 substances and products such as benzene, acetylene and gasoline are regulated according to the Ministry of Environment Notice No. 1998-77. It is a target. From solvents used in many industries to organic gases emitted from chemical and pharmaceutical factories or plastic drying processes, hydrocarbons commonly used in everyday life such as low boiling liquid fuel, paraffin, olefins, aromatic compounds, etc. do.

Furthermore, the sources of emissions include natural sources such as soil, wetlands, vegetation and grasslands, and artificial sources such as organic solvent use facilities, coating facilities, laundry, refineries, gas stations, and exhaust gas from various means of transportation. Most of these are mobile pollutants such as facilities and automobiles. Most countries are making efforts to reduce their emissions because they have a great impact on the environment and the human body.

Furthermore, in Korea, the Yeocheon Industrial Base, Ulsan, Mapo and Onsan Industrial Complexes were designated as special countermeasures based on the Air Environment Conservation Act amended in 1995. In December 1997, the Enforcement Decree of the Air Quality Preservation Act was amended to expand the scope of the regulation from hydrocarbons with raid vapor pressure of 27.6 kPa or higher to substances of 10.3 kPa or higher, and added gas stations as regulated facilities in October 1999. The Enforcement Decree of the Environmental Conservation Act has been amended to limit the range of raid vapor pressure so that harmful substances in substances below 10.3 kW can be managed. Emission control and prevention facilities should be installed in petroleum refining and petrochemical product refining facilities, storage and shipping facilities, refineries, gas stations, and laundry facilities within the areas designated as air-environmentally regulated areas.

Here, the malodorous substance and the volatile organic compound cause the particles (molecules) to volatilize, diffuse, and dilute, irritating the nose of the person, causing a smell, and causing dyspnea and growth disorders in the flora and fauna.

In recent years, the trend of pursuing comfort in the living environment is gradually increasing, and "odor" has also been attracting attention as one of the factors that inhibit it, and the countermeasures have been implemented by the government's enforcement of the odor prevention law.

However, people's feelings about unpleasant odors are various, and the individual's memories that come with odors intersect in various ways, so the difference of experience by individuals often appears as a difference in preference for odors. It is important to provide evidence.

Currently relevant markets include all facilities and workplaces where odors can occur, such as sewage and manure treatment plants, sanitary treatment plants and municipal waste collection facilities. The resulting processing capacity requires a large capacity of at least 100-500 Nm ³ / min.

Therefore, in line with the trend of stricter regulations on emission of odor and volatile organic compounds that impede the living environment around the world, especially developed countries, Korea also enacted odor prevention law by Act No. 7170 on February 9, 2004. In February, it started in earnest.

In addition, complex odor is applied to the air dilution sensory method of environmental pollution process test criteria in accordance with Article 6, Paragraph 1, Article 4 of the "Act on Environmental Testing and Inspection, etc.". Less than 300 The site boundary should be less than 10.

In particular, the need for facilities for such odors has increased due to the industrial society and the consolidation of environmental pollution and various contaminants, and the odor management has become the subject of strict regulations as the standards of environmental law are being strengthened. .

Therefore, it is evident that these standards will be applied and the standards will be more demanding where odors such as sewage and manure slaughterhouses are severe. Current deodorization systems do not have the capacity to meet these criteria and there is a need for more breakthrough deodorization systems.

Currently, various kinds of physical, chemical and biological methods are used to treat odor contained in the surrounding air, and representative examples are combustion, catalytic combustion, RTO, adsorption, chemical cleaning and biological treatment using microorganisms. Etc. are being applied in industrial sites.

In the conventional deodorization technology, the adsorption method having a relatively low initial investment cost uses the activated carbon adsorption capacity of the fine pores of the activated carbon, and the device structure has a simple advantage, but the activated carbon briquettes frequently increase the maintenance cost and remove the high concentration of ammonia. There is a falling problem.

In addition, physical and chemical methods have high pollutant removal efficiency but high operating costs such as facility cost, fuel cost, material cost, and chemical cost, and also cause secondary pollution sources (NOx, waste water, gas generated during adsorbent regeneration) and microorganisms. Biological treatment using is less expensive than the physical and chemical treatment method and economical because there is no secondary pollutant generation, there are problems such as the difficulty of microbial management technology.

The conventional techniques as described above have the aforementioned problems. BACKGROUND OF THE INVENTION A deodorizing apparatus for removing odors using a plasma method, which has recently been in the spotlight, has been commercialized.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, in the drawings, it is noted that the same components or parts are denoted by the same reference numerals as possible. In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted in order not to obscure the subject matter of the present invention.

First, as shown in Figures 1 to 3, looking at the configuration of the plasma deodorizing apparatus 10 according to the present invention, the electromagnetic wave generating unit 100 for generating electromagnetic waves, the reaction unit 200 and the electromagnetic wave is concentrated and odor and air supplied It consists of an ignition unit 300 that sparks electromagnetic waves.

Looking in more detail with respect to the plasma deodorizer 10 according to the present invention.

First, the electromagnetic wave generator 100 generates electromagnetic waves by electromagnetic resonance. In this case, the electromagnetic wave generating unit 100 includes a tuner 105 that generates electromagnetic waves at the magnetron 101 by electromagnetic resonance, bypasses the electromagnetic waves reflected by the magnetron 101 through the circulator 103, and outputs the electromagnetic waves by impedance matching.

That is, the plasma deodorizer 10 of the present invention uses an atmospheric plasma generated by electromagnetic waves, industrial odors, sewage treatment plants, public buildings, smoking rooms, large-capacity septic tanks, stormwater / sewage storage tanks, livestock houses, livestock wastewater treatment facilities, composting facilities, and Easily remove volatile organic compounds or various odorous gases that are inevitable in various production processes and environmental industries such as slaughterhouses. Therefore, since the substance causing deodorization is removed by chemical reaction or thermal decomposition using an atmospheric pressure plasma method generated by electromagnetic waves, the removal efficiency is high and the range of odor components that can be removed is widened.

Here, the magnetron 101 uses a second ground of pure copper as the anode and arranges the cathode and the grid in the axial direction. When the magnetic field is hung in the axial direction of the cathode, electrons protruding in the radial direction from the cathode are attracted to the anode and at the same time, the magnetic field receives a perpendicular force in the advancing direction.

As a result, the former is in spiral motion. Increasing the strength of the magnetic field increases the amount of bending of the electrons, and rotates many times before reaching the anode. When the strength of the magnetic field reaches a certain limit (critical magnetic flux density), electrons hardly reach the anode. At this time, a rotating electron pole is generated by electrons around the cathode, and an induction current is generated in the vibration circuit of the anode so that the vibration is stimulated and continued.

In addition, the electromagnetic wave generated in the magnetron 101 is reflected to bypass the reflected electromagnetic wave to prevent damaging the magnetron 101.

In addition, the tuner 105 performs an impedance matching function to increase the efficiency of power transmission. In this case, impedance matching refers to any method of reducing the reflection caused by the impedance difference between two different connection terminals when connecting one output terminal and an input terminal. Normally, a separate matching stage is inserted between two connection stages to correct the impedance difference between the two connection stages.

On the other hand, the electromagnetic wave generated in the electromagnetic wave generator 100 is applied to the reaction unit 200. At this time, the reaction unit 200 is the electromagnetic wave output through the electromagnetic wave generator 100 is concentrated in the discharge tube 210 and the odor and air is supplied through the hole 211 formed on one side of the discharge tube 210. At this time, the discharge tube 210 is formed in the opening hole 211 at the lower side of the side in the shape of the upper opening.

In particular, the quartz material of the discharge tube 210 is suitable, but is not limited to such a material. At this time, a high temperature arc occurs due to the concentration of energy on the outer wall of the discharge tube 210. Therefore, the gas entering the discharge tube 210 should have a fluid structure to disperse the energy formed on the outer wall of the discharge tube 210 while rotating at a high flow rate. As a result, the hot plasma is concentrated in the center of the discharge tube 210.

At this time, the ignition unit 300 installed below the reaction unit 200 allows the reaction unit 200 to be introduced only when sparking. At this time, the ignition unit 300 generates a spark while the first ground 310 and the second ground 320 contact each other. This ignition unit 300 operates through the driving unit 350. That is, the first ground 310 and the second ground 320 are introduced into the reaction unit 200 through the driving unit 350 to be in contact with each other to cause sparks and to be led out of the reaction unit 200 through the driving unit 350.

In this case, the driving unit 350 for introducing the ignition unit 300 into the reaction unit 200 may be applied in various ways.
