Description

Odor removal apparatus using ozone fog {Odor removing apparatus using ozone fog}

The present invention relates to an odor removal device, and more specifically, to an odor removal device that can more effectively remove odors by generating fine ozone water mist and reacting it with odor gases.

In general, large-scale livestock farms where cattle, pigs, chickens, ducks, etc. are raised produce a large amount of livestock waste and a strong odor caused by harmful gases.

Such odor not only causes inconvenience and resistance from nearby residents, but also has a negative impact on the health of livestock, so it is desirable to continuously purify and discharge harmful gases inside the livestock house using an odor removal device.

There are a variety of methods to remove odor, such as oxidation, cleaning, combustion, adsorption, and microbial treatment. In the livestock industry, the oxidation method uses the strong oxidation effect of ozone (O ₃ ) to remove odor components and consumes less power. It is widely used because it is efficient in processing large quantities of gas and is relatively easy to maintain.

Conventional odor removal devices utilizing ozone are configured by installing a nozzle at the source or movement path of odorous gas and spraying ozonated water containing ozone to oxidize and remove odor-causing substances.

To increase the efficiency of odor removal when spraying ozonated water through a nozzle, the ozone dissolved rate should be maximized by using a bubble system. If possible, ozonated water should be sprayed with a fine nozzle (aka fog nozzle) so that the ozonated water droplets stay in the air as long as possible and eliminate the cause of odor. It is desirable to bring it into contact with the material.

However, in reality, when fine nozzles (aka fog nozzles) are used, the parts (filters) inside the nozzle are easily corroded due to the strong oxidizing power of ozone water, which often causes the nozzle to break down. For this reason, most sites use fine nozzles. The situation is that it cannot be used and ozonated water is being sprayed through a regular nozzle.

However, because the ozone water droplets sprayed through a typical nozzle have relatively large particles, they inevitably stay in the air for a short time, which causes the problem that more ozone water must be sprayed to sufficiently treat the odorous gas.

In addition, as the spray amount of ozonated water increases, the tank storing the ozonated water must also become larger, which not only makes it difficult to manufacture a compact odor removal device, but also causes excessive increases in water and ozone gas consumption.

This includes cases where it happens. Additionally, when one component is directly connected or directly combined with another component, it means that no other elements are interposed. In addition, the fact that a part includes or is provided with a certain component does not mean that other components are excluded, but that it can further include or include other components, unless specifically stated to the contrary. In addition, in the drawings attached to this specification, there are parts that are exaggerated and different from the actual dimensions. This is only for convenience of explanation and understanding, and of course, the scope of the present invention should not be construed as limited or distorted due to this.

Figure 1 shows the configuration of an odor removal system according to an embodiment of the present invention, which includes an odor removal device 100 that processes odor gases using ozone water fog, and an odor removal device 100 on one side and the other side of the odor removal device 100, respectively. It includes a connected odor inlet pipe 310 and a process gas discharge pipe 320, and an activated carbon filter 400 and an ozone exhaust treatment unit 500 installed in order on the process gas discharge pipe 320.

As illustrated in FIGS. 2 to 4, the odor removal device 100 includes a housing 102 surrounding an internal space, a fog diffusion tank 130 installed horizontally inside the housing 102, and a fog diffusion tank 130. A horizontal partition wall 104 installed between the outer wall of the diffusion tank 130 and the inner wall of the housing 102 to divide the interior of the housing 102 into an upper space 110 and a lower space 120, and the housing 102 It includes an odor inlet hole 112 and a process gas discharge hole 114 formed on one side and the other, respectively, and communicating with the upper space 110.

In addition, a plurality of vertical partitions 140 are installed in the upper space 110 inside the odor removal device 100, and each vertical partition 140 has a lower flow path 142 or an upper flow path 144 through which odor gas can pass. ) is formed. Although not shown in the drawing, it is preferable that both edges of each vertical partition 140 are in close contact with the inner wall of the housing 102.

In an embodiment of the present invention, vertical partition walls 140 having a lower flow passage 142 and vertical partition walls 140 having an upper flow passage 144 are arranged alternately in the upper space 110. In this way, the inflow As the odorous gas flows in a zigzag form, the time it is in contact with the ozone water fog increases, which has the advantage of improving odor removal efficiency.

The lower space 120 inside the odor removal device 100 is provided with an ozone generator 150 and an ozone water fog generator 160.

The ozone water fog generated from the ozone water fog generator 160 is supplied to the inside of the fog diffusion tank 130 through the supply pipe 254, and the ozone water fog spread evenly in the diffusion space 132 inside the fog diffusion tank 130 is It is supplied to the upper space 110 through a plurality of through holes 134 formed on the upper surface of the fog diffusion tank 130.

Hereinafter, the ozonated water fog generator 160 will be described in more detail.

First, referring to FIGS. 5 to 7, the ozonated water fog generator 160 is connected to the ozonated water tank 165, the ultrasonic vibrator 200 installed inside the ozonated water tank 165, and the ozonated water tank 164, respectively. A circulation pump 170 for dissolving ozonated water and an ozonated water discharge pump 180, a water pipe 190 that supplies water to the ozonated water tank 165, a blowing pipe 252 coupled to one side of the ozonated water tank 165, and ozonated water. It includes an ozone water mist supply pipe 254 coupled to the ceiling of the tank 164.

The circulation pump 170 for ozonated water is connected to the ozonated water tank 165 through the ozonated water inlet pipe 171 and the ozonated water return pipe 172, and sets the dissolved amount of ozone in the ozonated water or water stored in the ozonated water tank 165. It plays a role in maintaining standards.

For example, the circulation pump 170 for dissolving ozone water mixes the ozone gas supplied from the ozone generator 150 through the ozone gas supply pipe 173 and the ozone water flowing in from the ozone water inlet pipe 171, and then flows the ozone water through the ozone water return pipe ( 172), the return process is repeated.

When spraying ozonated water into a nozzle, the ozonated water discharge pump 180 serves to supply ozonated water to the nozzle (not shown in the drawing) using the ozonated water discharge pipes 181 and 182. However, this ozone water discharge pump 180 may be omitted.

It is preferable that a water level controller be installed in the water pipe 190 that supplies water to the ozone water tank 165 to control the water level inside the tank. The type of water level controller is not particularly limited. For example, the opening and closing of the water pipe 190 may be mechanically controlled using the water level sensor 194 and the valve 192 linked thereto, and an electronic sensor and a solenoid valve may be used. The opening and closing of the water pipe 190 can also be controlled electronically.

Additionally, as illustrated in FIG. 7, the water pipe 190 can be opened and closed using the buoyancy bladder 195.

Meanwhile, in an embodiment of the present invention, in order to generate ozone water fog more efficiently and minimize the size of the device 100, as shown in FIGS. 5 and 6, the inner space of the ozone water tank 165 is formed into an ozone water circulation area ( 161), ozonated water supply area 162, and ozonated water fog generation area 163.

Looking specifically, the internal space of the ozone water tank 165 is divided into two spaces by the first partition 166, one end and the other end of which are respectively coupled to the inner wall of the ozone water tank 165. And the space on one side of the first partition 166 is used as the ozone water circulation area 161, and the space on the other side is divided again by the second partition 167 to form an ozone water quantitative supply area 162 and an ozone water fog generation area 163, respectively. It is used as.

The ozonated water circulation area 161 is an area in which ozonated water is continuously circulated by the circulation pump 170 for dissolving ozonated water. That is, the circulation pump 170 for dissolving ozonated water is connected to the ozonated water circulation area 161 through the ozonated water inlet pipe 171 and the ozonated water return pipe 172.

Meanwhile, the ozonated water return pipe 172 may be branched into an ozonated water supply pipe 175 for fog to supply ozonated water to the ozonated water supply area 162. In this case, the cross-sectional area of the ozonated water supply pipe 175 for fog is the ozone water return pipe. It is preferable that the cross-sectional area is smaller than (172). A valve 176 may be installed in the ozone water supply pipe 175 for fog.

Therefore, among the ozone water discharged from the ozone water dissolution circulation pump 170 to the ozone water return pipe 172, only a relatively small amount of ozone water is supplied to the ozone water constant supply area 162 through the fog ozone water supply pipe 175, and most of the ozone water is supplied to the ozone water supply area 162. The ozonated water is returned to the ozonated water circulation area (161).

The ozonated water supply area 162 is an area where ozonated water for fog is stored at a constant water level in order to supply ozonated water at a constant flow rate to the ozonated water fog generation area 163, and is different from the ozonated water circulation area 161 where the water level is not constant. 1 are isolated from each other by a partition wall 166.

The ozonated water fog generation area 163 is an area where a plurality of ultrasonic vibrators 200 vibrate the ozonated water with ultrasonic waves to generate ozonated water fog.

The ultrasonic vibrator 200 must be installed so that it is always located below the surface of the ozonated water supplied to the ozonated water supply area 162. In addition, in order to maximize the amount of ozonated water fog generated, the water level in the ozonated water fog generating area 163 where the ultrasonic transducer 200 is installed must be kept constant and stable in accordance with the set standards.

For this reason, in the embodiment of the present invention, the ozonated water quantitative supply area 162 is separately installed, and when the circulation pump 170 for ozonated water dissolved operates, the ozonated water is supplied to the ozonated water quantitative supply area 162 through the ozonated water supply pipe 175 for fog. After is continuously supplied and the ozone water is filled in the ozonated water supply area (162), the ozone water is designed to flow stably into the ozonated water fog generation area (163).

On the other hand, it is also possible to directly supply ozonated water to the upper part of the ultrasonic transducer 200 through the ozonated water supply pipe 175 for fog, but according to experiments, it is difficult to maintain the optimal water level stably due to fluctuations in the ozonated water, making the fog foggy. It was found that the amount of fog generated was rather reduced, and when ozonated water was supplied to the ozonated water supply area 162 as in the embodiment of the present invention and then naturally overflowed into the ozonated water fog generation area 163, the amount of fog generated increased significantly.

Referring to FIG. 6, ozonated water supplied to the ozonated water supply area 162 through the ozonated water supply pipe 175 for fog flows over the second partition wall 167 and into the ozonated water fog generation area 163.

At this time, since the ozone water supplied to the ozonated water supply area 162 must be prevented from overflowing directly into the ozone water circulation area 161 beyond the first partition wall 166, the height of the second partition wall 167 must be increased to the first partition wall 166. ) It is preferable to form a flow path 168 for ozone water flow at a lower level or at the top of the second partition wall 167.

In addition, in the ozonated water fog generation area 163, it is desirable that the amount of ozonated water is kept constant on the upper part of the ultrasonic vibrator 200. Therefore, the ozonated water supplied from the ozonated water supply area 162 does not remain, but when the water level exceeds a certain level, the ozonated water circulates. It is desirable to design the ozone water to be discharged into area 161.

To this end, it is desirable to form a flow path 169 for discharging ozone water at the top of the first partition wall 166 surrounding the ozone water fog generation area 163. In the drawing, the flow paths 168 and 169 formed in the first partition 166 and the second partition 167 are shown to have a rectangular cut shape, but this is only an example, and the flow paths 168 and 169 are formed in various shapes such as curved and V-shaped. may be formed.

However, it is preferable that the lowest point of the flow path 169 formed in the first partition 166 is lower than or equal to the lowest point of the flow path 168 formed in the second partition 167.

That is, it is preferable that the lowest point of the portion of the first partition 166 surrounding the ozone fog generation area 163 is lower than or equal to the lowest point of the second partition 167.

Only then can the ozone water flowing from the ozonated water supply area 162 into the ozone water fog generation area 163 naturally flow over the first partition wall 166 into the ozone water circulation area 161, thereby causing the ozonated water in the ozone water fog generation area 163. This is because the water level can be kept stable.

A blower 165a is formed on one side of the ozone water fog generation area 163 on the side wall of the ozonated water tank 165, and a blower pipe 252 and a blower fan 250 may be installed outside the blower hole 165a.

Additionally, a filter (258 in FIG. 4) may be installed on the inlet and/or outlet side of the blowing fan 250 to prevent external fine dust or foreign substances from flowing into the ozone water tank 165.

Additionally, one end of the ozonated water fog supply pipe 254 may be connected to the upper surface of the ozonated water tank 165, and the other end of the ozonated water fog supply pipe 254 may be connected to the lower surface of the fog diffusion tank 130.

Therefore, when the blowing fan 250 operates, the ozonated water fog generated in the ozonated water fog generation area 163 of the ozonated water tank 165 is supplied to the inside of the fog diffusion tank 130 through the ozonated water fog supply pipe 254, and the fog is supplied to the inside of the fog diffusion tank 130. After being spread evenly inside the diffusion tank 130, it is supplied into the upper space 110 through a plurality of through holes 134.

Meanwhile, in order to increase odor removal efficiency, the concentration of ozone contained in the ozonated water fog must be increased, and for this, the ozone dissolution rate in the ozonated water tank 165 must be increased.

To this end, in an embodiment of the present invention, as shown in FIG. 7, a bubble generator 210 is installed at the end of the ozone water return pipe 172 to collect water particles flowing in from the ozone water dissolving circulation pump 170 at a nanometer level. It plays a role in increasing the dissolved amount of ozone by decomposing it into ultrafine particles.

As illustrated in the cross-sectional view of FIG. 8, the bubble generator 210 includes a first body 211 and a second body 212, which are arranged in order along the flow direction of the fluid and each has a flow path communicating with each other. A plurality of disk-shaped filters 220 are installed inside the first body 211, and a barrel-shaped filter 230 is installed inside the second body 212.

The disk-type filter 220 and the barrel-type filter 230 are each made of a stainless steel mesh with fine holes, and serve to pulverize and/or decompose water particles into ultrafine particles.

As shown in FIG. 9, the plurality of disk-shaped filters 220 each include an inner filter 222 and a pair of outer filters 221 and 223 respectively disposed on both sides of the inner filter 222.

The inner filter 222 preferably has a thinner thickness than the outer filters 221 and 223. Additionally, the size of the grid through which fluid passes in the inner filter 222 is preferably smaller than that of the outer filters 221 and 223.

That is, the inner filter 222 preferably has a thinner thickness than the outer filters 221 and 223 and has smaller lattice holes.

In an embodiment of the present invention, four disc-shaped filters 220 are installed at predetermined intervals along the flow direction inside the first body 211 of the bubble generator 210, and thus the inflow water or ozone water is filtered through the disc-shaped filter. Each time it passes through (220), the amount decomposed into fine particles increases and the dissolved amount of ozone improves step by step.

In order to install a plurality of disk-shaped filters 220 at predetermined intervals, a plurality of support rings 240 are installed inside the first body 211, and a disk-shaped filter 220 is installed between adjacent support rings 240. ) can be installed. Additionally, the disk-shaped filter 220 located on the leftmost side in the drawing may be fixed between the end of the second body 212 and the support ring 240.

Meanwhile, the cylindrical filter 230 installed inside the second body 212 is manufactured by rolling a square stainless steel net into a cylindrical shape. In the embodiment of the present invention, the inner filter 222 of the disk-shaped filter 220 is It was manufactured by rolling up a stainless steel net made of the same material.

The tubular filter 230 preferably has a length longer than the diameter of the disk-shaped filter 220 based on the flow direction of the ozone water.

Accordingly, the tubular filter 230 serves to further improve the dissolved amount of ozone by pulverizing or decomposing the ozone water particles generated while passing through the disk-shaped filter 220 while preventing the recombination of the particles.

A fixing cap 245 for fixing the cylindrical filter 230 may be coupled to the end of the second body 212.

Meanwhile, as shown in FIGS. 2 to 4, an ozone treatment device 270 may be installed inside the upper space 110 on the downstream side where odorous gas flows. The ozone treatment device 270 is used to create ozonated water using water and ozone gas decomposed by the bubble generator 210, and to remove the remaining ozone gas components from being discharged to the outside. It thermally decomposes ozone gas using a heating element. It plays a role.

In the drawing, it is shown that the ozone treatment device 270 is installed from the processing gas discharge hole 114 to the upper flow path 144 of the second vertical partition 140, but the installation location is not limited to this. The ozone treatment device 270 may be installed from the process gas discharge hole 114 to the lower flow path 142 of the first vertical partition 140, may be installed in the process gas discharge hole 114, or may be installed in other locations. .

In addition, as shown in FIG. 1, when an ozone depletion processor 500 operating on the same principle is installed in the processing gas discharge pipe 320, the deozone treatment device 270 may be omitted in the odor removal device 100. It can be installed anywhere.

In addition, although not shown in the drawing, the lower space 120 of the odor removal device 100 according to an embodiment of the present invention includes an ozone generator 150, a circulation pump 170 for dissolving ozonated water, an ozonated water discharge pump 180, and an ultrasonic vibrator. (200), a power supply device that provides driving power for the blowing fan (250), the odor inflow fan (260), etc., and a control device that manually and/or automatically controls the operation of each of the components may be installed. .

Additionally, a concentration sensor capable of checking the ozone concentration of ozonated water stored in the ozonated water tank 165 may be installed, and the operation of the ozone water dissolution circulation pump 170 may be controlled using the detection result of the concentration sensor.

Hereinafter, the use and operation of the odor removal device 100 according to an embodiment of the present invention will be described with reference to the cross-sectional view of FIG. 7.

First, as shown in FIG. 1, an odor inlet pipe 310 communicating with an odor generating space such as a livestock barn is connected to the odor inlet hole 112 of the odor removal device 100 according to an embodiment of the present invention, and the treatment gas is discharged. A processing gas discharge pipe 320 is connected to the hole 114.

Next, when water is filled in the ozonated water circulation area 161 of the ozonated water tank 165 and the ozone generator 150 and the circulation pump 170 for dissolving ozonated water are operated, the circulation pump 170 for dissolving ozonated water is connected to the ozone water inlet pipe 171. The operation of mixing the water introduced through and the ozone gas supplied from the ozone generator 150 and returning it to the ozone water tank 165 through the ozone water return pipe 172 is repeatedly performed.

At this time, the mixed solution of water and ozone returned through the ozone water return pipe 172 passes through the bubble generator 210 and is pulverized and decomposed into ultrafine particles, greatly increasing the dissolved amount of ozone.

Subsequently, when the valve 176 of the ozone water supply pipe 175 for fog is opened after the ozone water concentration reaches the set standard, some of the ozone water discharged from the circulation pump 170 for ozonated water to the ozone water return pipe 172 is ozonated water for fog. It is supplied to the ozonated water fixed quantity supply area 162 of the ozone water tank 165 through the supply pipe 175, and the ozonated water filled in the ozonated water fixed quantity supply area 162 crosses the second partition wall 167 and flows into the ozone water fog generation area 163. supplied.

When the ultrasonic vibrator 200 is operated in this state, part of the ozone water flowing into the ozone water fog generation area 163 is converted into ozone water fog due to the vibration of the ultrasonic vibrator 200 and spreads upward, and the remainder is spread upward through the first partition ( 166) and is returned to the ozone water circulation area (161).

In addition, when the blowing fan 250 installed on one side of the ozonated water tank 165 is operated, the ozonated water fog generated in the ozonated water fog generation area 163 due to the wind pressure provided through the blower 165a) flows into the inside of the fog diffusion tank 130. moves and spreads.

The ozone water fog diffused inside the fog diffusion tank 130 moves to the upper space 110 through the through hole 134 and fills the interior of the upper space 110.

In this state, when odorous gas flows in through the odor inlet hole 112, the odorous gas flows in a zigzag fashion while passing through the lower flow path 142 and the upper flow path 144 of the plurality of vertical partitions 140 in the upper space 110. In this process, the odor-causing substances are oxidized by ozone water fog and then discharged into the treatment gas discharge pipe 300 through the treatment gas discharge hole 114.

In addition, the ozone gas component and the remaining odor component contained in the treated gas discharged through the treated gas discharge pipe 300 are the activated carbon installed in the ozone depletion processor 270 and/or the discharge pipe 300 installed inside the odor removal device 100. In the process of passing through the filter 400 and the ozone treatment unit 500, it is adsorbed, decomposed, and removed.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited thereto and may be implemented through various modifications or modifications in the specific application process.

As an example, in an embodiment of the present invention, four disc-shaped filters 220 are installed inside the bubble generator 210, but the number of disc-shaped filters 220 is not necessarily limited to this. In addition, the drawing shows that the first body 211 on which the disk-type filter 220 of the bubble generator 210 is mounted and the second body 212 on which the barrel-type filter 230 is mounted can be disassembled. However, this is limited to this. Since this is not the case, both the disk-type filter 220 and the barrel-type filter 230 may be installed in one body.

As another example, the odor removal device 100 according to an embodiment of the present invention was developed for the purpose of removing odor from livestock waste, but its use is not necessarily limited thereto, and is used in various fields such as sewage treatment plants and food waste treatment plants. It can be used to remove bad odors.

As such, the present invention can be implemented in various forms by being transformed or modified, and it is natural that the modified or modified embodiments fall within the scope of the invention as long as they include the technical idea of the invention disclosed in the patent claims described later. .
