Description

Barn air handler

The present invention relates to a barn air treatment apparatus that can remove the odor-causing substances of the barn raising livestock, such as cattle and pigs.

Unpleasant odors by stimulating the sense of smell can damage human's pleasant life and health. In particular, ammonia, hydrogen sulfide, mercaptan, and amines, which are the main causes of odor, are most likely to have discomfort and disgust even at low concentrations of ppm or below. In addition to the deterioration, the service industry, such as restaurants and lodging businesses, has been seriously damaged, and the necessity of developing odor reduction technologies to remove odors is emerging.

Conventionally, oxidation, adsorption, biological decomposition, masking, plasma decomposition, and the like are known as treatment methods for removing odors.

As one of the conventional odor treatment methods, the chemical oxidation method is a method of oxidizing and decomposing odorous substances using chemical oxidants (chlorine dioxide, sodium hypochlorite, chlorine dioxide), and various kinds of odors can be effectively removed. There is a problem that chemicals can affect human health and oxidants themselves cause environmental pollution.

In addition, as another conventional odor treatment method, the adsorption method is a method of adsorbing and removing malodorous substances by using an adsorbent having a large specific surface area (surface area per unit mass), such as activated carbon. However, in the adsorption method, since the odor-causing material is adsorbed semi-permanently in the adsorbent, there is a troublesome and inconvenient problem of periodically replacing the adsorbent at the time when the adsorbent is saturated, thereby increasing the maintenance and repair costs.

As such, most conventional odor treatment methods have various problems such as adversely affecting human health or increasing maintenance costs.

In addition, according to the conventional odor treatment method has a problem that the removal efficiency of the odor is low and the application point and the application range is very limited, even if the installation is difficult to operate and manage the facility, there is a problem in practicality.

In particular, the livestock odor is difficult to process because a large amount of odor causing substances in the air, and in particular, the fat and oil components contained in the livestock odor is not easy to remove.

Accordingly, in recent years, some countermeasures have been proposed for the air conditioning apparatus of the house for improving the efficiency of removing the odor and reducing the maintenance cost. However, there is still a need for development thereof.

The present invention provides an atmospheric treatment apparatus for a livestock house that can enhance the treatment effect of odor causing substances and can treat air having a high concentration of odor causing substances in a large amount.

The present invention can minimize the power consumption required for odor treatment, can reduce the operating cost and provides a standby treatment apparatus that can reduce the processing time.

The present invention provides a barn air treatment apparatus capable of optimizing the air discharged after the malodor is removed.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, the atmospheric treatment apparatus for removing the odor causing substances contained in the air, the odor treatment housing including the suction duct and the discharge duct, suction A dust removal washing chamber including a washing nozzle for treating the air flowing into the duct with the sprayed liquid, and a first gas-liquid separation chamber including a first filter for removing the liquid contained in the air treated in the dust removing washing chamber. , A plasma processing chamber for treating air treated in the first gas-liquid separation chamber with plasma, an ultraviolet processing chamber for treating air treated in the plasma processing chamber with ultraviolet rays, and a processing nozzle for treating air treated in the ultraviolet processing chamber with the injected liquid Wet processing chamber comprising a, and removing the liquid contained in the air treated in the wet processing chamber A second filter, and it is possible to include a second gas-liquid separation chamber for discharge through the outlet duct of the air processed by the second filter.

In the case of foreign matters contained in odor-causing substances, in particular, fats and oils contained in livestock odors, existing filters have limitations in treatment and have to be frequently exchanged, resulting in high maintenance costs. However, in the air treatment device of the house according to the present invention, by removing the foreign substances such as dust or oil contained in the air by using the liquid strongly sprayed from the odor causing substances in the cleaning nozzle, reducing the burden of cost, It is possible.

As described above, most of the odor-causing substances remaining in the relatively clean air by being treated in the dust removal washing chamber may be decomposed again in the plasma processing chamber.

On the other hand, since the high pressure liquid injected from the dust removal washing chamber may remain in the air, the liquid contained in the air treated in the dust removal washing chamber is once removed from the first gas-liquid separation chamber including the first filter. It can be supplied to the plasma processing chamber.

The first filter uses a demister filter capable of effectively removing the liquid, and additionally, can cleanly filter out any remaining fat or oil.

The air treated in the plasma treatment chamber is treated with ultraviolet rays in the ultraviolet treatment chamber, and the odor causing substance may be reprocessed through the ultraviolet rays.

On the other hand, the reason for placing the ultraviolet processing chamber behind the plasma processing chamber is very large. Specifically, in the plasma processing chamber, a large amount of plasma active ingredient gases such as ozone, OH, O ₂ H ₂ and O are generated by plasma discharge such as positive corona discharge. When entering the process chamber, it reacts with ultraviolet light and becomes very active. That is, the plasma active ingredient gas which is excellent in the effect of decomposition and sterilization of odor-causing substances can be greatly activated by ultraviolet rays, so that the effects of decomposition and sterilization of odor-causing substances can be greatly increased.

In addition, a plurality of ultraviolet lamps for generating ultraviolet rays are disposed in the ultraviolet treatment chamber, and quartz tubes are disposed outside the ultraviolet lamps to protect the ultraviolet lamps. In addition, the UV lamps can be staggered or arranged in a grid to minimize the resistance of the air passing therethrough.

The air treated in the UV treatment chamber is introduced into the wet treatment chamber, and the wet treatment chamber includes a treatment nozzle for treating the incoming air with the injected liquid.

On the other hand, a plurality of internal spacers are alternately arranged inside the wet processing chamber to bypass the air passing through the inside of the wet processing chamber from side to side, and a plurality of processing nozzles are disposed along the movement path of the air at each upper portion of the internal separation plate. By increasing the possible air and liquid contact, the limited space efficiency is greatly increased.

In addition, the inner partition plate may be fixed to the inner wall provided inside the odor treatment housing, the free end of the inner partition plate is not fixed to the inner wall is inclined downward than the fixed end fixed to the inner wall liquid is injected from the treatment nozzle You can let it flow down.

In addition, the air treated in the ultraviolet treatment chamber is introduced from the bottom of the wet treatment chamber to be discharged to the upper portion of the wet treatment chamber, which has a great meaning. Specifically, the air treated in the wet treatment chamber is discharged through the discharge duct, and the air passed through the wet treatment chamber contains a large amount of liquid in the form of a gas or a drop. can do. Therefore, it is possible to prevent the loss of the liquid discharged to the outside as it is through the discharge duct.

Of course, the air treated in the wet treatment chamber may be removed from the second gas-liquid separation chamber including the second filter and then discharged to the discharge duct, and the second filter may also effectively remove the liquid like the first filter. Demister filters can be used.

In addition, the plasma processing chamber may be disposed above the wet processing chamber. This arrangement is for discharging the liquid generated in the plasma processing chamber or possibly lost in the first gas-liquid separation chamber to the wet processing chamber located below.

In addition, the atmosphere treatment apparatus of the house may include a chemical storage tank for storing the liquid supplied to the washing nozzle and the processing nozzle and the chemical storage tank for supplying the chemicals to the chemical storage tank.

Meanwhile, the chemical storage tank is disposed under the dust removal washing chamber and the wet treatment chamber, and this arrangement structure plays a very important role. Specifically, when the chemical storage tank is located below the dust removal washing chamber or the wet processing chamber, the chemical liquid sprayed from the washing nozzle and the processing nozzle may naturally flow down to be recovered into the chemical storage tank. By reusing it, it is possible to avoid the use of large quantities of drugs, and to realize both cost saving and environmental conservation.

In addition, the chemicals stored in the chemical storage tank are neutralized by the plasma active ingredient gas contained in the air treated in the UV treatment chamber, in particular, ozone which may greatly damage the environment if it is discharged to the outside, or add untreated odor causing substances in the air. It may contain kinds that can be removed. For example, the drug may include at least one of sodium hydroxide (NaOH), sulfuric acid (sulfuric acid), sodium hypochlorite (NaOCl), citric acid, and phosphoric acid. In particular, the above agents can be used for the purpose of neutralizing ozone in the wet treatment chamber.

In addition, the air treatment device of the house may include an acidity meter for measuring the acidity of the chemical storage tank, according to the acidity of the chemical storage tank measured by the acid meter to properly dispense the drug from the chemical storage tank to the chemical storage tank. Can supply

In addition, the plasma processing chamber includes a plurality of ground electrode plates extending along the flow direction of air, and the side edges are disposed to face the ground electrode plates between the plurality of ground electrode plates, and are disposed perpendicular to the flow direction of the air to provide air. It may include a discharge electrode flowing elastically by the flow pressure of. Therefore, the odor-causing substance can be removed by corona discharge occurring at the edges of the ground electrode plate and the discharge electrode.

The discharge electrodes are disposed perpendicular to the flow direction of the air so that the discharge electrodes elastically flow under the flow pressure of the air, so that the edges of the discharge electrode flowing back and forth along the flow direction of the air are corona discharged only at a specific point of the ground electrode plate Corona discharge is generated in a large area between the facing ground electrode plates while flowing. Even if the same power consumption is supplied, the odor treatment efficiency is higher than when the discharge electrode is fixed, and the operating cost can be reduced and the processing time can be shortened.

In addition, compared to the case where the corona discharge occurs only at a specific point facing the edge of the discharge electrode because the discharge electrode does not move, the moving discharge electrode causes the corona discharge with the ground electrode plate in a relatively large area. It is prevented that the temperature of a certain point of the electrode rises sharply. The required heat resistance of the ground electrode plate and the discharge electrode can be lowered, and the use of expensive materials such as tungsten or titanium with high heat resistance can be lowered, thereby reducing the manufacturing cost of the ground electrode plate or the discharge electrode.

In addition, since the temperature of the ground electrode plate or the discharge electrode does not increase rapidly due to corona discharge, the oxidation of the ground electrode plate or the discharge electrode is minimized, and thus the semi-permanent use of the ground electrode plate or the discharge electrode is possible, thereby reducing the maintenance cost. do.

In addition, since the discharge electrodes flow back and forth in the air flow direction but do not move toward the ground electrode plate, the discharge electrode and the ground electrode plate can be kept at a constant distance at all times, and thus the corona discharge is discharged between the discharge electrode and the ground electrode plate. The intensity of the voltage for generating is kept constant, so that voltage control for generating corona discharge is very easy.

On the other hand, as mentioned above, the discharge electrode may be installed to elastically flow back and forth with respect to the flow direction of the air. For example, a rod-shaped discharge electrode connection conductor may be disposed at the upper end and the lower end of the discharge electrode, and at least one of the upper end and the lower end of the discharge electrode may be provided in a winding shape to surround the outer circumference of the discharge electrode connection conductor.

In addition, at the rear of the discharge space defined by the discharge electrode and the ground electrode plate, at least one of graphene oxide and titanium dioxide (TiO ₂ ) for changing the optical properties of ultraviolet rays and visible rays generated during corona discharge. A photocatalyst filter having a coating layer including any one may be disposed. Here, the change in the optical properties may mean that the ultraviolet and visible light are more activated.

For reference, in the present invention, the malodor causing substance may include particulate and gaseous malodor causing substances contained in the air. As an example, the odor causing substance may include not only bacteria and viruses but also formaldehyde, ammonia, hydrogen sulfide, mercaptan, and amines.

The air treatment apparatus of the house according to the present invention increases the treatment effect of odor causing substances by treating odor causing substances in multiple angles through injection liquid, plasma, ultraviolet rays, etc., and treats air having a high concentration of odor causing substances in large capacity. can do.

In addition, in the case of fats and oils contained in odor-causing substances, in particular in the livestock odors, the existing filter has a limitation of treatment, and the burden of the maintenance cost was large because it must be frequently replaced, but the atmosphere of the barn according to the present invention The treatment apparatus removes foreign substances such as dust or fat contained through the liquid strongly sprayed from the cleaning nozzle, thereby reducing the burden of cost and enabling large-capacity treatment.

In addition, by placing the UV treatment chamber behind the plasma treatment chamber in the atmospheric treatment apparatus of the livestock according to the present invention, a large amount of plasma active ingredient gas generated in the plasma treatment chamber is greatly activated as it enters the ultraviolet treatment chamber, thereby causing Degradation and sterilization effect can be greatly increased.

In addition, in the atmospheric treatment apparatus of the house according to the present invention, a plurality of internal spacers may be alternately disposed inside the wet treatment chamber to bypass air passing through the inside of the wet treatment chamber from side to side, and the treatment nozzle may be disposed at each upper portion of the internal separator. Plural arrangements along the air movement path increase the contact between air and liquid as much as possible, thereby greatly increasing the limited space efficiency.

In addition, the air to be treated in the ultraviolet treatment chamber in the atmospheric treatment apparatus of the house according to the present invention is introduced from the bottom of the wet treatment chamber to be discharged to the upper portion of the wet treatment chamber, so that a large amount of liquid in the form of droplets enclosed as the air rises to the top naturally free. Allow to fall. Therefore, it is possible to prevent the loss of the liquid discharged to the outside as it is through the discharge duct.

In addition, in the atmospheric treatment apparatus of the livestock house according to the present invention, the plasma processing chamber may be disposed above the wet processing chamber, and the arrangement may be performed by placing the liquid in the lower portion of the liquid which has not been removed in the plasma processing chamber or may be removed from the first gas-liquid separation chamber. Can be discharged to the treatment chamber.

In addition, in the air treatment apparatus of the house according to the present invention, the chemical storage tank is disposed under the dust removal washing chamber and the wet processing chamber, so that the chemical liquid sprayed from the washing nozzle and the processing nozzle flows downward to be recovered into the chemical storage tank. do. In addition, by reusing the recovered chemicals can be used to avoid the use of a large amount of drugs, it is possible to implement both the effect of cost reduction and environmental conservation.

In addition, the atmospheric treatment apparatus of the house according to the present invention by optimizing the liquid discharged after the odor is removed by neutralizing a liquid containing a chemical capable of neutralizing a large amount of activation gas generated by the plasma in the wet treatment chamber can do.

In addition, in the atmospheric treatment apparatus of the house according to the present invention, the discharge electrodes of the plasma processing chamber may be disposed perpendicular to the flow direction of the air so that the discharge electrodes may elastically flow by the flow pressure of the air. The edges of the discharge electrode flowing back and forth along the flow direction of air do not cause corona discharge only at a specific point of the ground electrode plate, but cause a corona discharge in a large area between the facing ground electrode plates while flowing. Even if the same power consumption is supplied, the odor treatment efficiency is higher than when the discharge electrode is fixed, and the operating cost can be reduced and the processing time can be shortened.

In addition, since the discharge electrode moving in the atmospheric treatment apparatus of the house according to the present invention causes corona discharge together with the ground electrode plate in a relatively large area, the temperature of a specific point of the ground electrode plate or the discharge electrode is prevented from rising sharply, and thus the grounding is performed. The required heat resistance of the electrode plate and the discharge electrode can be lowered. Therefore, the use of expensive materials such as tungsten or titanium with high heat resistance can be lowered, so that the manufacturing cost of the ground electrode plate or the discharge electrode can be lowered, and the temperature of the ground electrode plate or the discharge electrode due to corona discharge does not increase rapidly. Therefore, the semi-permanent use of the ground electrode plate or the discharge electrode is possible, thereby reducing the maintenance cost.

In addition, the discharge electrodes in the atmospheric treatment apparatus of the house according to the present invention flows back and forth in the flow direction of air but does not move toward the ground electrode plate, the discharge electrode and the ground electrode plate can always maintain a constant distance, the discharge The intensity of the voltage for generating corona discharge is kept constant between the electrode and the ground electrode plate, so that the voltage control for generating corona discharge is very easy.

For reference, in the present description, the same numbers refer to substantially the same elements, and may be described by referring to the contents described in the other drawings under these rules, and the contents determined to be obvious to those skilled in the art or repeated may be omitted.

The barn air treatment device according to the present invention can be installed throughout livestock odor or household waste, and industrial waste devices, and other organic fertilizer factories, aseptic animal breeding rooms, animal laboratories, chemical production facilities, sports centers, subway stations It may be used to remove odor causing substances contained in the air by being installed in a constant temperature and humidity warehouse, a clean room facility, etc. The present invention is not limited or limited by the application field and the installation place of the atmospheric treatment apparatus of the house.

1 to 6, the atmospheric treatment apparatus 100 of the livestock house according to the present embodiment may include an odor treatment housing 110, a dust removal washing chamber 120, a first gas-liquid separation chamber 130, and a plasma processing chamber ( 200, an ultraviolet treatment chamber 140, a wet treatment chamber 150, and a second gas-liquid separation chamber 160.

On one side of the malodor treatment housing 110 is a suction duct 112 for sucking air having a bad smell cause material and a discharge duct 114 for treating the bad smell cause material to discharge the air.

The suction duct 112 and the discharge duct 114 are disposed side by side on the odor treatment housing 110. Ducts installed in parallel to each other make field working conditions more efficient.

In the case of fats and oils contained in odor-causing substances, in particular, fats and oils contained in livestock odors, the existing filter has a limitation of treatment and has to be frequently replaced, resulting in a large burden of maintenance costs.

However, by removing the foreign substances such as dust or oil contained in the odor causing substances through the liquid strongly sprayed from the washing nozzle 122 of the dust removal washing chamber 120, it is possible to reduce the burden of the cost, and to process a large capacity. .

However, the outer side of the suction duct 112 may be arranged to filter out the first large foreign matter.

First, most of the odor-causing substances remaining in the relatively clean air by being processed in the dust removal washing chamber 120 may be further decomposed in the plasma processing chamber 200.

Meanwhile, since the high pressure liquid injected from the dust removing washing chamber 120 may remain in the air, the air treated in the dust removing washing chamber 120 may include a first filter 132 containing the liquid containing the first filter 132. After being removed from the one gas-liquid separation chamber 130, it may be supplied to the plasma processing chamber 200.

The first filter 132 may use a demister filter capable of effectively removing the liquid, and may additionally filter out the remaining fat and oil components.

For reference, the first gas-liquid separation chamber 130 is disposed at the rear side based on the moving direction of air of the dust removing washing chamber 120. Specifically, the suction duct 112 provides a space for connecting the plasma processing chamber 200 from the inlet thereof, and the shape of the suction duct 112 is approximately U-shaped, and the liquid injected from the washing nozzle 122 is transferred to the plasma processing chamber 200. The first gas-liquid separation chamber 130 is located behind the dust removal washing chamber 120 so as not to be transferred as it is.

This also applies to the second gas-liquid separation chamber 160. Specifically, the discharge duct 114 provides a space for connecting the wet process chamber 150 to the discharge port of the discharge duct 114, the shape is approximately U-shaped, the air just before the discharge duct 114 is discharged Bar is discharged through the wet processing chamber 150, it is possible to remove a large amount of water drops contained in the air to export. Therefore, the second gas-liquid separation chamber 160 may be disposed between the wet processing chamber 150 and the outlet of the discharge duct 114.

That is, in practice, the first and second gas-

liquid separation chambers

130 and 160 may be said to be located inside the suction duct 112 and the discharge duct 114, respectively.

The air processed in the plasma processing chamber 200 is again treated with ultraviolet rays in the ultraviolet processing chamber 140, and may reprocess the odor causing substance through the ultraviolet rays.

On the other hand, the reason why the ultraviolet processing chamber 140 is placed behind the plasma processing chamber 200 is very large. Specifically, the plasma processing chamber 200 generates a large amount of plasma active ingredient gases such as ozone, OH, O ₂ H ₂ , O through plasma discharge such as positive corona discharge, and the plasma active ingredient gas is contained in the air. When it enters the ultraviolet treatment chamber 140 in a state, it is very active by reacting with the ultraviolet rays. In other words, the plasma active ingredient gas having excellent effects of decomposition and sterilization of odor-causing substances is greatly activated by ultraviolet rays, so that the effects of decomposition and sterilization of odor-causing substances are greatly increased.

In addition, a plurality of ultraviolet lamps 142 for generating ultraviolet rays are disposed in the ultraviolet processing chamber 140, and quartz tubes are disposed outside the ultraviolet lamps 142 to protect the ultraviolet lamps. The ultraviolet lamps 142 can be staggered or arranged in a grid to minimize the resistance of the air passing therethrough.

As an ultraviolet lamp, UV-C lamps that generate short waves of approximately 200 to 280 nm wavelength can be used, and the sterilization and photolysis effects of the photooxidation method are excellent. The photooxidation method may have a superior effect than using ozone alone. Specifically, hydrogen peroxide is formed as an intermediate in the initial reaction stage in which ozone generated in a low temperature plasma processing chamber is photonized by ultraviolet energy, and OH radicals are not toxic and can sterilize / disinfect all materials. As a result, the sterilizing power of ultraviolet rays and ozone can be increased by more than 100 times.

As described above, the air treated in the ultraviolet treatment chamber 140 is introduced into the wet treatment chamber 150, and the wet treatment chamber 150 includes a plurality of treatment nozzles 152 for treating the incoming air with the injected liquid.

In addition, it is preferable that the droplet diameter of the liquid sprayed from the processing nozzle 152 is appropriately increased so that the spray diameter of the nozzle is largely adjusted so that the sprayed droplet is not scattered at the flow rate of the gas even in the large air volume treatment.

Meanwhile, a plurality of internal spacers 154 are alternately disposed inside the wet processing chamber 150 to bypass the air passing through the wet processing chamber 150 to the left and right, and the internal spacers 154 alternately disposed. The outlets of the air passing between the grids are arranged in a lattice arrangement, and a plurality of treatment nozzles 152 are disposed along each air gap 154 along the movement path of the air, thereby increasing the contact between the liquid and the air. Significantly increase space efficiency.

In addition, the inner partition plate 154 is fixed to the inner wall provided inside the malodor treatment housing 110, the free end 155 of the inner partition plate 154 not fixed to the inner wall 157 is connected to the inner wall 157. The liquid sprayed from the processing nozzle 152 may be inclined downward from the fixed end 156 to be fixed to flow downward.

In addition, the air processed in the ultraviolet treatment chamber 140 is introduced from the lower portion of the wet treatment chamber 150 to be discharged to the upper portion of the wet treatment chamber 150, which has a great meaning. Specifically, the air treated in the wet processing chamber 150 is discharged through the discharge duct 114, the air passing through the wet processing chamber 150 contains a large amount of liquid in the form of gas or droplets, As the liquid rises to the top, it can naturally fall freely. Therefore, it is possible to prevent the loss of the liquid discharged to the outside as it is through the discharge duct 114.

Of course, the air treated in the wet processing chamber 150 may be removed from the second gas-liquid separation chamber 160 including the second filter 162 and then discharged to the discharge duct 114, and the second filter ( Like the first filter 132, the 162 may use a demister filter capable of effectively removing the liquid.

In this embodiment, the plasma processing chamber 200 is disposed above the wet processing chamber 150. This arrangement is for discharging the liquid generated in the plasma processing chamber 200 or possibly not removed from the first gas-liquid separation chamber 130 to the wet processing chamber 150 located below.

In addition, a drain pipe is disposed at the bottom of the plasma processing chamber 200, or a water support and a drain pipe / valve are installed to automatically discharge the liquid downward.

In addition, the air treatment apparatus 100 of the house is a chemical storage tank for supplying chemicals to the chemical liquid storage tank 102 and the chemical liquid storage tank 102 for storing the liquid supplied to the washing nozzle 122 and the processing nozzle 152 ( 104).

In the chemical storage tank 104 may be supplied to the chemical storage tank 102 through the pump, the chemical liquid storage tank 102 is also stored in the chemical liquid stored in the washing nozzle 122 and the processing nozzle 152 through the pump Can supply That is, the liquid sprayed from the cleaning nozzle 122 or the processing nozzle 152, which has been mentioned above, may be the chemical liquid.

On the other hand, the chemical storage tank 102 is disposed below the dust removal washing chamber 120 and the wet treatment chamber 150, this arrangement structure plays a very important role. Specifically, the chemical storage tank 102 is located below the dust removal washing chamber 120 or the wet processing chamber 150, and the chemical liquid sprayed from the washing nozzle 122 and the processing nozzle 152 flows down naturally to store the chemical liquid. It can be recovered to the water tank 102, and by reusing the recovered chemical liquid, it is possible to reduce the cost burden for chemical liquid replenishment, and also to protect the environment.

In addition, the chemicals stored in the chemical storage tank 104 is neutralized by the plasma active ingredient gas included in the air treated in the ultraviolet treatment chamber 140, in particular, ozone which may greatly damage the environment when discharged to the outside, or untreated in the air. It may include a kind that can further remove the odor causing substance. For example, the drug may include at least one of sodium hydroxide (NaOH), sulfuric acid (sulfuric acid), sodium hypochlorite (NaOCl), citric acid, and phosphoric acid.

For reference, ozone is difficult to discharge to the outside as it is an environmentally harmful substance. Therefore, although almost treated by the chemical, it is preferable to remove even a small amount of ozone. For this purpose, an ozone filter may be further disposed to remove ozone behind the plasma processing chamber. Here, the rear side is based on the moving direction of air.

The ozone filter may be provided immediately behind the ultraviolet treatment unit, or may be provided behind the wet treatment chamber or the second gas-liquid separation chamber.

As the ozone filter, a filter filled with a material such as a charclal filter, manganese dioxide (MnO ₂ ), and copper oxide may be used.

In addition, when the odor treatment is not performed by plasma or ultraviolet rays and the wet treatment chamber is not operated, it is also possible to use a dry filter as the filter of the gas-liquid separation chamber mentioned above.

In addition, the chemical storage tank may be disposed with an acidity meter 106 for measuring the acidity (acidity) of the chemical stored in the chemical storage tank, the chemical storage tank 104 according to the acidity of the chemical storage tank 102 measured by the acidity meter Drugs can be properly supplied to the chemical storage tank (102).

The barn air treatment apparatus 100 is a complex system apparatus that overcomes the limitations of the existing independent plasma treatment method, ultraviolet lamp method, and wet treatment method, and can maximize efficiency while minimizing installation space.

Although it depends on the concentration of odor-causing substances, the treatment capacity standard is, for example, the processing air volume of a general pig house (stock house), for example, the processing air volume is about 50 to 80 CMM (processing capacity of 50 to 80 m 3 per minute), and the processing material is a livestock odor. It can be used as a low energy consumption device with a power consumption of 1.8KWH (except exhaust power). The dimensions are 2,500 mm wide x 1,500 mm wide x 2,000 mm high), and the weight is about 1,200 kg. In addition, a visual inspection window is installed on the front surface to check the driving state of the equipment with the naked eye, thereby ensuring a space for checking a function and replacing internal parts.

For reference, the injection pressure of the injection nozzle of the dust cleaning chamber is 0.2MPa or more, giving a strong impact on the air, so that it is easy to process the holding components in the air. The above-described dust washing chamber may be separately configured in some cases to treat air alone.

Hereinafter, the plasma processing chamber of the present invention will be described with reference to FIGS. 7 to 10, and FIGS. 7 to 9 are plan views, side views, and front views of the plasma processing chamber, and FIG. 10 is a discharge electrode of the plasma processing chamber. It is a partially enlarged view for demonstrating elastically flowing along a flow direction.

7 to 10, the plasma processing chamber 200 includes a ground electrode plate 210 and a discharge electrode 220 for corona discharge, and the ground electrode plate 210 and the discharge electrode are plasma housing 202. It is placed inside. The housing 202 is disposed on a flow path of air to be treated, and an inlet for introducing air to be treated is formed at one side of the housing 202, and air in which odor causing substances are removed at the other side of the housing 202. An outlet for discharging is formed. In the present embodiment, the housing 202 is described as an example in which a substantially rectangular cylinder is formed, but the present invention is not limited or limited by the structure of the shape of the housing 202.

The ground electrode plate 210 is provided as a rectangular plate disposed side by side in the movement path of the air extending from the inlet to the outlet of the housing 202, the plurality of ground electrode plate 210 is disposed in parallel to each other.

The ground electrode plate 210 is fixed to the inside of the housing 202 by a plurality of fixing intervals 204 which penetrate the ground electrode plate 210 and both ends thereof are fixed to the side wall of the housing 202, and the fixing interval ( As illustrated in FIGS. 7 to 9, the through holes 204 are also disposed in the middle in addition to the upper and lower parts of the ground electrode plate 210.

The ground electrode plate 210 whose position is fixed by the fixed interval 204 is limited to move in a direction perpendicular to the flow direction of air, and thus the distance to the discharge electrode 220 may be kept constant.

On the other hand, the discharge electrodes 220 are provided in an elongated rectangular band shape, the edges thereof may be disposed adjacent to face the plate surface of the ground electrode plate 210, a plurality of them are arranged in a line between the ground electrode plate 210 do.

The power supply unit is provided to apply power for corona discharge to the ground electrode plate 210 and the discharge electrode 220, and is grounded when power is supplied to the ground electrode plate 210 and the discharge electrode 220 through the power supply unit. Corona discharge is generated in the corona discharge space between the electrode plate 210 and the discharge electrode 220.

As described above, as the corona discharge is generated between the discharge electrode 220 and the ground electrode plate 210, various chemically active specie are formed between the edge of the discharge electrode 220 and the ground electrode plate 210. Can be generated. For example, normal oxidative active species may be formed in the corona discharge space by corona discharge, and odor causing substances passing through the corona discharge space may be removed by the oxidative active species.

On the other hand, when looking at the discharge electrode 220 of the present embodiment enlarged on the left side of Figure 10 a plurality of discharge projections 225 protruding toward the ground electrode plate 210 may be formed on the side edge, through the low voltage Corona discharge can also occur easily.

For reference, in the present invention, the malodor causing substance may include particulate and gaseous malodor causing substances contained in the air. As one example, the odor causing substance may include formaldehyde, ammonia, hydrogen sulfide, mercaptan, amines, and the like.

By supplying air having odor-causing substances to the discharge space in which the ground electrode plate 210 and the discharge electrode 220 are disposed, the odor-causing substances can be easily removed, and the flow rate of air supplied to the discharge space is adjusted or discharged. By adjusting the size of the space, it is possible to treat a large amount of air having a high concentration of odor-causing substances relatively simply.

In addition, in the present invention, the discharge electrode 220 may be installed to elastically flow back and forth with respect to the flow direction of air. Specifically, the rod-shaped discharge electrode connection conductor 206 is disposed at the upper end and the lower end of the discharge electrode 220, and the upper end and the lower end of the discharge electrode 220 are provided in a winding shape surrounding the outer circumference of the discharge electrode connection conductor.

Accordingly, the discharge electrodes 220 disposed perpendicular to the flow direction of the air may elastically flow back and forth by the flow pressure of the air, and the edge of the discharge electrode 220 flowing back and forth along the flow direction of the air may be grounded. Corona discharge is not generated only at a specific point of the electrode plate 210, but corona discharge is generated in a large area between the ground electrode plates 210 facing each other while flowing. Even if the same power consumption is supplied, the odor treatment efficiency is higher than when the discharge electrode is fixed, and the operating cost can be reduced and the processing time can be shortened.

In addition, since the discharge electrode 220 moving back and forth generates a corona discharge together with the ground electrode plate 210 in a relatively large area, the temperature of a specific point of the ground electrode plate 210 or the discharge electrode 220 is prevented from rising rapidly. do. The required heat resistance of the ground electrode plate 210 and the discharge electrode 220 can be lowered, and the use of expensive materials such as tungsten or titanium with high heat resistance can be lowered, thereby lowering the manufacturing cost of the ground electrode plate or the discharge electrode. It also works. In particular, since the temperature does not rise rapidly, the ground electrode plate may use an aluminum plate.

In addition, since the temperature of the ground electrode plate 210 or the discharge electrode 220 does not increase rapidly due to corona discharge, oxidation of the ground electrode plate 210 or the discharge electrode 220 is minimized, and thus the ground electrode plate 210 is minimized. Or semi-permanent use of the discharge electrode 220 is reduced maintenance costs.

In addition, since the discharge electrodes 220 flow back and forth in the air flow direction, but do not move toward the ground electrode plate 210, the discharge electrode 220 and the ground electrode plate 210 may maintain a constant distance at all times. As a result, the intensity of the voltage for generating corona discharge is kept constant between the discharge electrode 220 and the ground electrode plate 210, so that voltage control for generating corona discharge is very easy.

On the other hand, the power supply may adjust the voltage in accordance with the concentration of the source of the bad smell to prevent power waste.

In addition, by using a positive and negative voltage crossover applied to the discharge electrode and the ground electrode plate by full-wave rectification of the AC voltage, the positive and negative corona discharge is periodically generated to cause odor-causing substances naturally in the air flow phase. You can drop out. In addition, full-wave rectification of the AC voltage may be implemented using a conventional bridge circuit, and the present invention is not limited or limited by the type and characteristics of the bridge circuit.

On the other hand, a safety accident may occur when a current leaks into the housing 202 because a high voltage current is transmitted to the discharge electrode 220 and the ground electrode plate 210 by the above-described power supply. Therefore, an electrode plate fixing member 208 manufactured using a high voltage insulator for accommodating the upper and lower ends of the discharge electrode 220 and the ground electrode plate 210 may be disposed. As the electrode plate fixing member 208, an ethylene resin having good heat resistance such as polytetrafluoroetylene may be used. In addition, Teflon has a high surface roughness and has the advantage of preventing foreign matter from adhering to it.

On the other hand, the atmospheric air treatment apparatus 200 may include a foreign material removal filter 230 for pretreating the air to be treated. For example, the foreign matter removing filter 230 may be mounted before the inlet of the housing 202, and foreign substances such as dust contained in the air flowing into the housing 202 may be filtered by the foreign matter removing filter 230. Can be.

In addition, a photocatalyst filter 240 having a coating layer including at least one of graphene oxide and titanium dioxide that changes optical properties of ultraviolet rays and visible rays generated during corona discharge may be disposed at the rear of the discharge space. Here, the change in the optical properties may mean that the ultraviolet and visible light is more activated. As the photocatalytic material, TiO ₂ , ZnO, CdS, graphene oxide, or the like may be used.

For reference, the power supplied to the above-mentioned UV treatment chamber and plasma treatment chamber may be manually or automatically operated from a control panel provided at one side of the housing, and may be supplied from the chemical reservoir to the chemical reservoir in the pump and the chemical reservoir for supplying the chemical to the nozzle. Manipulation may be made with respect to pumps for supplying the chemicals.

As described above, although described with reference to the preferred embodiment of the present invention, those skilled in the art various modifications and variations of the present invention without departing from the spirit and scope of the invention described in the claims below I can understand that you can.
