Description

Apparatus for purifying gas and method for purifying

The present invention relates to a gas purifying apparatus and a purifying method, and more particularly, a gas purifying apparatus and a purifying apparatus capable of removing odor components in a gas discharged from a odor generating facility such as a sewage treatment plant, an incinerator, a food waste treatment facility, a landfill, and the like. It is about a method.

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. Air pollutants and odors generated from these odor generating facilities are becoming complaints of local residents.

As odor components, ammonia, methylmercaptan, hydrogen sulfide, methyl sulfide, methyl disulfide, trimethylamine, acetaldehyde, styrene and the like are regulated by legal regulations. 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 present invention has been made to improve the above problems, the gas purification device and purification method to increase the removal efficiency of the odor component by first oxidizing the odor component using a catalyst and second oxidation of the odor component by ozone. The purpose is to provide.

2 is a cross-sectional view showing an ozone oxidation unit applied to a gas purifying apparatus according to another embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings will be described in detail a gas purifying apparatus according to a preferred embodiment of the present invention.

Referring to FIG. 1, the gas purifying apparatus of the present invention includes a gas inlet 10, a catalytic oxidation unit 30, an ozone oxidation unit 50, a condensation unit 110, and heating means. .

The gas inlet 10 is for introducing a gas containing a malodorous component into the catalytic oxidation unit 30. For example, the gas inlet 10 is connected to a malodor generating facility so that a gas containing malodorous component is introduced therein. The gas inlet line 11, the first and second gas transfer lines 13 and 15 branched from the gas inlet line 11, and the first and second gas transfer lines 13 and 15, respectively. First and second suction fans 17 and 19 are provided.

In the present specification, 'odor component' means hydrogen sulfide, mercaptans, amines, and other irritating gaseous substances that stimulate the sense of smell of humans, causing discomfort and aversion. Odors include ammonia, methylmercaptan, hydrogen sulfide, methyl sulfide, methyl disulfide, trimethylamine, acetaldehyde, styrene and the like. The substances causing these odors vary greatly depending on the source of odors.The main odor generating facilities include sewage treatment plants, incinerators, food waste treatment facilities, landfills, manure and livestock wastewater treatment plants, oil refineries, oil refineries, and chemical plants. have.

The gas flowing through the gas inlet line 11 is supplied to the catalytic oxidation unit 30 through the first and second gas transfer lines 13 and 15, and preferably, the gas is transferred to the first and second gas transfer lines. Alternately flows into lines 13 and 15. That is, the gas passing through the gas inflow line 11 flows into the first gas transfer line 13 and then flows into the second gas transfer line 15 when the inflow into the first gas transfer line 13 stops. When the inflow into the second gas transfer line 15 is stopped, the second gas transfer line 13 flows back into the first gas transfer line 13. Therefore, when gas flows into the first gas transfer line 13, the gas does not flow into the second gas transfer line 15, but when gas flows into the second gas transfer line 15, the first gas transfer line ( 13) No gas enters

As such, the first and second suction fans 17 installed in the first and second gas transfer lines 13 and 15 to alternately flow gas into the first and second gas transfer lines 13 and 15. (19) alternately controls the flow paths of the first and second gas transfer lines (13) and (15). The first suction fan 17 and the second suction fan 19 operate alternately while the gas is introduced through the gas inlet line 11. When the first suction fan 17 operates, the second suction fan 19 does not operate. When the second suction fan 19 operates, the first suction fan 17 does not operate. Thus, the first and second suction fans 17 and 19 operate intermittently rather than continuously. The operating cycle is determined according to the gas residence time in the first and second catalytic reactors 31 and 33 which will be described later. For example, the operating cycle can be set within 0.5 to 5 seconds. Operation of the first and second suction fans 17 and 19 may be automatically controlled by a controller.

Heating means for heating the gas flowing along the first and second gas transfer lines 13 and 15 will be described later. The heating means raises the temperature of the gas so that the solid catalyst has oxidation activity by heat.

The gas supplied through the first and second gas transfer lines 13 and 15 is in contact with the solid catalyst in the catalytic oxidation unit 30 so that the odor component in the gas is first oxidized.

The illustrated catalytic oxidation section 30 is composed of two catalytic reactors connected to the first and second gas transfer lines 13 and 15, respectively. That is, the first catalyst reactor 31 connected to the first gas transfer line 13 and filled with the solid catalyst therein, and the second catalyst connected to the second gas transfer line 15 and filled with the solid catalyst therein The reactor 33 is provided.

The first and second catalyst reactors 31 and 33 are provided with a honeycomb ceramic carrier having a plurality of spherical holes therein, and a solid catalyst is filled in the form of particles in the carrier. In addition, the solid catalyst may be coated on the surface of the carrier coated with alumina. Instead of the ceramic carrier, a solid catalyst dispersed and coated on a wire-shaped metal carrier such as an aluminum alloy can be used.

Pd, Ru, Ni, Pt, Au, Ag, etc. may be used as the solid catalyst, and MnO ₂ , CoO ₃ , Fe ₂ 2O ₃ , SnO ₃ , ZnO, CuO, TiO _2, etc. may be used as the metal oxide system. have. The solid catalyst has activity of oxidation and reduction by heat.

In the first and second catalyst reactors 31 and 33, the gas stays for a predetermined time so that the odor component in the gas is first oxidized by the solid catalyst. The present invention uses a batch reacter rather than operating the first and second catalytic reactors 31 and 33 as a plug flow reacter to increase the oxidation reaction efficiency in the catalytic oxidation unit 30. It is desirable to operate as.

As described above, since the gas flows into the first and second catalyst reactors 31 and 33 alternately through the first and second gas transfer lines 13 and 15, the gas is supplied through the gas inlet line 11. While maintaining the inflow of the first and second catalytic reactors (31, 33) in a batch operation is possible. Gas introduced into the first and second catalytic reactors 31 and 33 is restricted from entering and leaving until the reaction takes place. Gases reacted in the first and second catalyst reactors 31 and 33 during the residence time are respectively controlled by the first and second gas discharge lines 36 by the operation of the first and second dampers 38 and 39. The gas is discharged through the 37. The first and second dampers 38 and 39 are also operated alternately in the same way as the first and second suction fans 17 and 19. Buffers 34 and 35 may be installed at the rear ends of the first and second catalytic reactors 31 and 33, respectively.

The first and second gas discharge lines 36 and 37 are connected by one connection line 40. The connection line 40 is connected to the ozone oxidation unit 50 so that the first gas oxidized by the catalytic oxidation unit 30 is introduced.

The ozone oxidation unit 50 is composed of an ozone generator 67 and a cylindrical body 51 to which ozone generated from the ozone generator 67 is supplied, and a gas which is primarily oxidized from the catalytic oxidation unit 30 is introduced. . The ozone generator 67 is connected to the connection line 40 through the ozone supply line 69.

Ozone has high oxidative properties and has been widely applied to gas and wastewater treatment in order to disinfect water or remove organic compound portions from water. The reaction between ozone and organic compounds can be separated into direct reactions and indirect reactions. The reaction can be accelerated under appropriate concentrations of oxidants such as H ₂ O ₂ , OH ⁻ .

It is important to increase the contact between ozone and gas in order to increase the oxidation treatment efficiency of the gas by ozone. To this end, the ozone oxidation unit mixes ozone generated from the ozone generator as shown in FIG. 2 inside the main body 51 by the diffusion blade 55 to increase the contact of the ozone gas.

Referring to FIG. 2, an inlet is formed at the front end of the main body 51 and an outlet is formed at the rear end. The connection line 40 is connected to the front end of the main body 51 in which the inlet is formed. And one side of the connection line 40 is connected to the ozone supply line (69). A housing 81 is installed at the rear end of the main body 51 in which the outlet port is formed, and an impeller 83 for sucking gas and ozone is installed inside the housing 81. The impeller 83 is coupled to the rotation shaft 53.

The rotating shaft 53 is installed to horizontally cross the inner space of the main body 51 and the housing 81. The rotary shaft 53 is rotatably supported on one side of the support bar 52 installed at the inlet of the main body 51, and the other side is rotatably supported on the side wall of the housing 81.

The drive unit 90 for driving the rotary shaft 53 includes an electric motor 91 installed outside the housing 81 and a power transmission means for transmitting the rotational force of the electric motor 91 to the rotary shaft 53. The drive pulley 93 coupled to the drive shaft of the electric motor 91 by the power transmission means, the driven pulley 95 coupled to the end of the rotary shaft 53, the drive pulley 93 and the driven pulley 95 are connected It consists of a belt 97. Unlike shown, the power transmission means may be made of a drive and driven sprocket, and a chain connecting both sprockets.

A plurality of diffusion blades 55 are coupled to the rotating shaft 53 located inside the main body 51 at regular intervals. The rotation radius of the diffusion blade 55 is preferably formed from 6/10 to 8/10 of the radius of the main body 51. The diffusion blade 65 is a gas and ozone introduced into the interior of the main body 51 by the impeller 63 in a direction in which the radius of the main body 51 extends, that is, in the direction of the inner circumferential surface of the main body 51 in the rotation shaft 53. It plays a role in pushing out. At this time, the flow of the fluid pressurized in the direction of the inner circumferential surface by the rotation of the diffusion blade 55 and the flow of the fluid coming back to the inner circumferential surface of the main body 51 collide with the inside of the main body 51. The pressure of the generated fluid further enhances contact between ozone and gas by vibrating the diaphragm 70 provided on the inner circumferential surface of the main body 51.

The diaphragm 70 is coupled to the end of the spring 75 fixed to the fastener 71 which is screwed with the main body 51. The diaphragms are installed at regular intervals along the inner surface of the main body 51 so as to be adjacent to the rotational trajectories of the respective blades. The diaphragm 70 supported by the spring 75 is vibrated by the pressure of the fluid generated inside the main body 51, thereby vibrating the fluid around the diaphragm 70, thereby greatly increasing the contact between ozone and gas. .

Gas oxidized secondarily in the ozone oxidation unit 50 having the above-described configuration is introduced into the condensation unit 110 through the third gas discharge line 89 together with ozone as shown in FIG. 1.

The condensation unit 110 is connected to the ozone oxidation unit 50 through the third gas discharge line 89 and is installed in the cooling tank 111 and the cooling tank 111 in which the secondary oxidation gas flows, and is cooled. Peltier element 115 for absorbing heat from the gas to cool the gas introduced into the tank 111 is provided. A condensate discharge line 119 is disposed below the cooling tank 111 to discharge condensed water, and a treatment gas discharge line 117 is disposed above the cooling tank 111 to discharge the finally processed treatment gas. .

The Peltier element 115 is a thermoelectric element in which one side is cooled and the other side is heated when electricity is supplied, and is applied to various industrial fields. The cooling surface of the Peltier element 115 becomes a heat absorbing portion, and the heating surface becomes a heat radiating portion. Therefore, the Peltier element 115 is installed so that the heat absorbing portion faces the inside of the cooling tank. The Peltier element 115 receives power and absorbs heat from the gas introduced into the cooling tank to cool the gas. Thus, the cooling method using the Peltier element 115 is a well-known technique (Korean Patent Publication No. 2003-0010305, Japanese Patent Publication No. 2007-0014670, etc.), and a detailed description thereof will be omitted.

The gas introduced into the cooling tank 111 condenses residual odor components or various organic contaminants contained in the gas by cooling. In addition, the ozone introduced with the gas is dissolved in the condensed water, thereby preventing the ozone from being discharged together with the processing gas discharged to the top of the cooling tank, or reducing the emission amount.

The present invention uses the Peltier element 115 as a cooling source of the condensation unit 110 to cool the gas and simultaneously heat the gas flowing from the Peltier element 115 into the catalytic oxidation unit 30. It can be used as a heat source.

The heating means using heat emitted from the Peltier element 115 as a heat source includes a first heat exchanger 100 and a first heat exchanger 100 that heat the heat exchange medium by receiving heat from the heat radiating portion of the Peltier element 115. And a second heat exchanger 107 which is connected to the heat exchange medium and flows through the heat exchange medium, and is connected to the heat exchange medium transfer line 105 to heat the gas flowing through the gas inlet 10. One second heat exchanger 107 is installed in each of the first and second gas transfer lines 13 and 15.

The first heat exchanger 100 heats the heat exchange medium by heat exchange with the high temperature heat emitted from the heat radiating portion of the Peltier element 115. Although not shown, the first heat exchanger 100 includes a heat storage tank having an inner space in contact with the heat dissipation portion of the Peltier element 115, and a heat transfer pipe installed inside the heat storage tank to receive heat from the heat dissipation portion of the Peltier element 115. Is made of. One end of the heat transfer pipe is connected to the heat exchange medium inlet line 101, and the other end is connected to the heat exchange medium transfer line 105 so that air introduced through the heat exchange medium inlet line 101 flows therein. On the other hand, a heat sink and a plurality of heat dissipation fins may be installed in the heat dissipation portion of the Peltier element for increasing the heat dissipation area of the Peltier element and for rapid heat transfer.

In the example illustrated as a heat exchange medium, air is used, but water may be used in addition to air.

Although not shown, when the heat emitted from the Peltier element 115 is insufficient as a heat source for heating the gas to a predetermined temperature, an auxiliary heat source for supplementing the heat source may be further provided in the heating means. A heater is installed in the heat exchange medium inflow line 101 through which air flows into the first exchanger 100 as an auxiliary heat source, or heaters for heating gas in the first and second gas transfer lines 13 and 15 are respectively provided. Can be installed.

The gas purifying method of the present invention using the above-described gas purifying apparatus includes a heating step, a catalytic oxidation step, an ozone oxidation step, a condensation step, and a heat exchange step.

In the heating step, the gas containing the malodorous component introduced through the gas inlet 10 is heated in advance. The heating of the gas is performed by using heating means. The present invention heats the gas using heat generated from the condensation unit 110.

The gas flowing through the gas inlet line 11 is heated by heat exchange with a second heat exchanger 107 installed in the first and second gas transfer lines 17 and 19, respectively, and then the first and second catalyst reactors ( 31) (33). At this time, the first and second gas transfer lines 13 and 15 by alternating operation of the first and second suction fans 17 and 19 installed in the first and second gas transfer lines 17 and 19. Crack down on the flow paths. Therefore, gas flows into the first catalyst reactor 31 and the second catalyst reactor 33 alternately.

During the catalytic oxidation step, the gas contacts the solid catalyst and the odor component is first oxidized, and then, in the ozone oxidation step, the gas is contacted with ozone to oxidize the odor component in the gas secondly. Of course, the ozone oxidation unit shown in FIG. 2 may be applied to increase the contact between ozone and gas in the ozone oxidation step.

In the ozone oxidation step, the second oxidation-treated gas is introduced into the cooling tank 111 in which the Peltier element 115 is installed to perform a condensation step of condensing residual odor components in the gas. In the condensation step, malodorous components or various organic pollutants in the gas are condensed, and ozone is dissolved in the condensed water. And the processing gas of the non-condensed gas state is discharged through the upper part of the cooling tank 111.

Next, heat emitted from the Peltier element 115 in the heat exchange step is transferred to the gas. That is, air that is a heat exchange medium flowing into the first heat exchanger 100 is circulated to the second heat exchanger 107 after heat exchange with heat emitted from the Peltier element 115. In the second heat exchanger 107, the heat exchange medium exchanges heat with the gas flowing through the first and second gas transfer lines 13 and 15.
