Description

Air purification device {Apparatus For filtering Air Pollution}

The present invention relates to an air purification apparatus, and more particularly, to an air purification apparatus capable of purifying pollutants contained in the atmosphere.

Recently, air pollution has caused various environmental problems. There are many causes of air pollution, but the use of fossil fuels is known to be one of the biggest causes. Pollutants contained in the atmosphere include nitrogen oxides (NOx) and sulfur oxides (SOx) generated by combustion of fossil fuels. In addition, pollutants include various kinds of dust in addition to substances generated by combustion of fossil fuels. Dust is a particulate air pollutant with a diameter of 10 micrometers or less, and can be divided into airborne dust and fine dust.

In addition, it is preferable that a compressor 362 and various compressed air passages connected to the compressor 362 are installed in the third housing 36 .

Of course, the manner in which various components of the air purification device are installed in the second housing 34 and the third housing 36 is not limited thereto, and it is of course possible to appropriately change the arrangement in consideration of space utilization.

Each component will be described in detail as follows.

First, the first filter unit 12 and the first filter cleaning unit 66 will be described in detail with reference to FIGS. 4 to 6 . The first filter unit 12 is illustrated and described using a filtration type filter as an example.

First, the first filter unit 12 will be described. Two rotating shafts 122 are installed vertically and horizontally across the air purification passage F1. Sprockets 124 are respectively installed at both ends of the rotation shaft 122 , and a pair of chains 126 are engaged with the sprockets 124 . One of the plurality of rotation shafts 122 (driving rotation shaft) 122a is connected to the gearbox 120 , and the gearbox 120 is connected to the motor M.

Meanwhile, a plurality of support members 128 are connected between the pair of chains 126 . The filter unit 130a is coupled to the support member 128 . For example, one filter unit 130a is coupled to the two support members 128 , and a plurality of filter units 130a are all connected to each other to finally form a single filter 130 . In this way, the overall shape of the filter 130 becomes a substantially tetrahedral shape having a hollow portion. Although not limited, it is preferable that the filter unit 130a is made of a flexible material, for example, a nonwoven fabric. This is because the filter unit 130a rotates. The type of the filter unit 130a or the filter 130 is not limited, and it is possible to select and use a filter unit or filter suitable for air pollution purification. For example, the filter mainly includes a HEPA filter that filters bacteria and dust, a pre-filter that mainly filters foreign substances and dust, a deodorization filter, a composite filter, etc. In this embodiment, a pre-filter is used to mainly collect re-scattering dust. it is possible to do Moreover, it is possible to select suitably also in the case of the filtration performance of a filter. For example, in this embodiment, in order to remove dust of 10 μm or less, it is possible to use a filter of 0.5 to 1 μm/m 2 .

5 shows that the support member 128 is coupled to the inner surface of the chain 126, the present embodiment is not limited thereto. For example, the support member 128 may be coupled to the upper surface of the chain 126 . In Fig. 5, 126a, 126b, and 126c denote unit elements of a chain.

In addition, in FIG. 5 , a plurality of filter units 130a are coupled to the support member 128 to constitute one filter as a whole, but it is also possible to use one filter over the entire support member 128 .

Referring to FIG. 4 , the power transmission relationship will be described as follows.

As an actuator, the motor M will be described as an example. The output shaft M1 of the motor M is connected to the first gearbox 120 , and the output shaft of the first gearbox becomes the driving rotation shaft 122a of the first filter unit 12 . It is also possible to rotate the second filter unit 2, which will be described later, using one motor M. That is, the other output shaft M2 of the motor may be connected to the second gearbox 224 , and the output shaft of the second gearbox 224 may be the driving rotation shaft 222a of the second filter unit 20 .

The power transmission process is described as follows.

When the motor M rotates, the rotational force of the motor 20 is transmitted to the driving rotational shaft 122a of the first filter unit 12 through the first gearbox 120 to rotate the driving rotational shaft 122a. When the driving rotating shaft 122a rotates, the sprocket 124 provided on the driving rotating shaft 122a rotates, and the other rotating shaft 122 connected to the sprocket 124 also rotates. When the rotation shaft 122 of the first filter unit 12 rotates, the chain 126 meshed with the rotation shaft 122 also rotates, and the filter 130 coupled to the chain 126 also rotates. It is preferable that the filter 130 rotates (counterclockwise in FIG. 2 ) so that the portion in contact with the air introduced into the air purification passage F1 is sequentially moved downward. Because, when more than a predetermined amount of dust is attached to the filter 130 , this part rotates downward and the dust attached to the filter 130 is removed by the first filter cleaning unit 66 , and flows to the dust collection passage F2 . because it has to be sent. In addition, the filter 130 may rotate continuously or may rotate at a predetermined time interval. That is, it is possible to determine the time required until the dust is collected in the filter 130 and it is difficult to function as a filter anymore by experiment or calculation, and to rotate the filter 130 in units of this time interval.

Since the power transmission process of the second filter unit 2 is the same as the power transmission process of the first filter unit 12 , a description thereof will be omitted.

On the other hand, it is preferable that a reduction gear is provided inside the first gearbox 120 and the second gearbox 224 . Also, a gear capable of changing a rotation direction, for example, a helical bevel gear, may be used inside the first gearbox 120 and the second gearbox 224 . The configuration of the gears of the first gearbox 120 and the second gearbox 224 is widely known to those skilled in the art, so a detailed description thereof will be omitted.

For example, it is also possible to use two motors that respectively drive the first filter unit 12 and the second filter unit 2 . Also, in the present embodiment, the use of the sprocket 124 and the chain 126 as components of the power transmission device has been shown and described, but the present invention is not limited thereto, and other suitable power transmission devices may be used. . For example, it is also possible to use a friction wheel, a belt, or the like.

The overall shape of the filter 130 of the first filter unit 12 is a shape having a hollow part, and an air gun 363 is provided in the inside (hollow part) of the filter of the first filter part 12 . A compressed air inlet 367 is connected to one side of the air gun 363 and a plurality of injection holes 366 are provided at the lower portion. The lower portion of the injection hole 366 is preferably provided with a guide 364 for guiding the compressed air to be injected. In addition, an opening 322 for communicating the air purification passage F1 and the dust collection passage F2 is provided at the lower portion of the portion where the air gun 363 is provided. (See FIG. 2)

The compressed air inlet 367 of the air gun 363 is preferably connected to a device for compressing air ('compressor' for convenience). For example, compressed air from the compressor 362 is delivered to the inside of the air gun 363 , and the compressed air delivered to the air gun 363 is ejected to the outside through a plurality of injection holes 366 . The compressed air injected through the plurality of injection holes 366 is injected from the inside to the outside of the filter 130 of the first filter unit 12 to separate the dust collected in the filter 130 . The separated dust is sent to the dust collection passage F2 through the opening 322 between the air purification passage F1 and the dust collection passage F2. The dust separated and guided to the dust collection passage F2 flows through the dust collection passage and is finally collected in the dust box 26 .

2 and 7, the second filter unit 2 will be described. The second filter unit 2 will be described using an electrostatic precipitation filter as an example. Since it is generally used as an electrostatic precipitation filter, it will be mainly described with reference to the part related to the present embodiment.

The second filter unit 2 may include a static electricity generating unit 18 that largely generates static electricity and an electrostatic adsorption unit 20 that adsorbs dust ionized in the static electricity generating unit 18 .

Since the electrostatic adsorption unit 20 is similar to the structure of the first filter unit 12, differences will be mainly described. A chain 204 is engaged with the sprockets 202 provided at both ends of the plurality of rotation shafts. One shaft (driving rotation shaft) 222a among the plurality of rotation shafts is connected to the second gearbox 224 (see FIG. 4 ).

Referring to FIG. 7 , the electrostatic adsorption unit 20 of the second filter unit 2 will be described.

The structure of the electrostatic adsorption unit 20 of the second filter unit 2 is similar to that of the first filter unit 12 . However, in the first filter unit 12, a filter unit is provided, and each filter unit is connected without being spaced apart from each other, and the filter as a whole substantially surrounds the support member, and thus has a substantially tetrahedral shape having a hollow part. In addition, in the first filter unit 12, the filter unit is provided to connect the plurality of support members. However, the electrostatic adsorption unit 20 of the second filter unit 2 is provided with adsorption fins 230 spaced apart from each other so that air flows between the adsorption fins 230 .

In detail, it is as follows. A support member 228 is connected between the pair of chains 204 of the electrostatic adsorption unit 20 of the second filter unit 2 . In addition, the adsorption pins 230 are coupled to each of the support members 228 . In the electrostatic adsorption unit 20 of the second filter unit 2 , the adsorption pins 230 are installed substantially vertically with respect to each support member 228 . Accordingly, each of the adsorption pins 230 are installed to be spaced apart from each other, and thus a space is created between each of the adsorption pins 230 . As the ionized air flows into the space, the dust is electrostatically adsorbed to the suction pin 230 .

As shown in FIG. 2 , the structure of the second filter cleaning unit 68 is basically the same as that of the first filter cleaning unit 66 . That is, the second filter cleaning unit 68 includes an air gun 682 , a compressed air inlet 684 is connected to one side of the air gun 682 , and a plurality of injection holes are provided in the lower portion. The second filter cleaning unit 68 is preferably provided so that the guide provided in the air gun 682 can spray compressed air in the direction of the suction pins 230 rather than the space between the suction pins 230 . That is, the guide is preferably provided to be inclined at a predetermined angle from the vertical.

On the other hand, as shown in Figure 6, the first filter cleaning unit 66 and the second filter cleaning unit 68 is preferably used together with one compressor (362). And it is preferable to provide the valves 369 and 689 in each of the flow passages 367 and 684 to selectively control the flow of compressed air.

2 and 8, the dust separation unit 24 will be described as follows.

The dust separation unit 24 functions to collect the dust filtered in the air purification passage F1 and guided to the dust collection passage F2 into the dust box 26 . Preferably, the dust separation unit 24 includes a first member 242 that rotates and a second member 244 that is fixedly installed and guided to the dust collection passage F2 is finally collected. .

The structure of the first member 242 is similar to that of the electrostatic adsorption unit 20 of the second filter unit 2 . However, a flexible portion 230a formed of a flexible material is provided instead of the suction pin 230 of the electrostatic absorption portion 20 of the second filter portion 2 . That is, the structure of the first member 242 other than the flexible part 230a is substantially the same as that of the electrostatic adsorption part 20 of the second filter part 2 .

Therefore, similarly to the electrostatic adsorption unit 20 of the second filter unit 2 , a space is formed between the flexible parts 230a of the first main member 242 , and air containing dust flows into this space. do. In addition, it is preferable that the tip of the flexible portion 230a of the first member 242 is installed to contact the second member 244 . In addition, it is preferable that the first member 242 rotates clockwise so that the flexible portion 230a scrapes the second member 244 from the top to the bottom.

As shown in FIG. 8 , the flexible portion 230a has a certain degree of rigidity so that it can gently scratch the surface of the second member 244 without being damaged when in contact with the second member 244 while maintaining a predetermined shape. It can be used as long as it can be used. For example, the edge portion 230a may be made of a flexible material such as a non-woven fabric. In addition, the flexible portion 230a coupled to one support member 128b may be one, or the flexible portion 230a may be a plurality of flexible portions 230a coupled to one support member 128b.

The second member 244 is preferably installed at the rear of the first member 242 . The second member 244 is installed to substantially block the dust collection passage F2, and it is preferable to use a structure having a hole smaller than that of dust. That is, the second member 244 serves as a kind of filter, and a filtration type filter may be used.

On the other hand, the dust box 26 is located under the dust separation unit 24, and it is preferable that the first box 26 is detachably installed. An opening 247 communicating with the dust box 26 is provided at a lower portion of a portion where the first member 242 and the second member 244 contact each other, and an opening 26a corresponding thereto is also provided on the upper portion of the dust box 26 . ) is preferably provided. And, it is preferable that the blowing fan 28 is provided on the rear side of the second member. The blowing fan 28 preferably functions to suck the air flowing through the dust collection passage F2 to the outside of the air purification device.

In addition, a plurality of protrusions 246 may be provided at the lower portion of the dust separation unit 24 , and a communication unit 248 communicating with the dust box 26 may be provided between the protrusions 246 . With this configuration, as the first member 242 rotates, the flexible portion 230a of the first member 242 collides with the protrusion 246 , and the dust attached to the flexible portion 230a is separated.

A process in which the dust of the dust collection passage F2 is collected into the dust box 26 will be described as follows.

The dust introduced into the dust collection passage F2 passes between the flexible portions 230a of the first member 242 to reach the second member 244 . Since the second member 244 is a kind of filter, it is attached to the second member 244 without first passing through the second member 244 . Then, air other than dust passes through the second member 244 and goes out. At this time, the flexible portion 230a of the first member 242 rotates clockwise while in contact with the second member 244 . Accordingly, the flexible portion 230a of the first member 242 scratches the second member 244 from the top to the bottom, and thus the flexible portion 230a of the first member 242 is on the second member 244 . Remove the attached dust. The separated dust is collected into the dust box 26 through the openings 247 and 26a.

In addition, as the first member 242 continues to rotate, the flexible portion 230a of the first member 242 collides with the protrusion 246 . Then, the dust attached to the flexible part 230a of the first member 242 is separated, and the separated dust is collected into the dust box 26 through the communication part 248 . When the dust box 26 is full of dust, the dust box 26 is separated to throw away the dust.

The first member 242 according to the present embodiment is not limited thereto. The first member 242 may be used as long as it has a structure capable of separating dust attached to the second member 244 while rotating. For example, as shown in FIG. 9 , the first member 242 may include a single rotating shaft 2422 and a flexible portion 2424 radially coupled to the rotating shaft 2422 . Also in this embodiment, similar to that shown in FIG. 8 , it is possible to configure one or a plurality of flexible portions 2424 . In addition, in this embodiment, in order to prevent the first member 242 from interfering with the flow of air in the dust collection passage F2, the first member 242 is formed smaller than the size of the dust collection passage F2. , it is preferable to configure the first member 242 to scrape off dust while moving the second member 244 up and down.

With reference to FIGS. 2 and 3 , the blower generator 42 , the sterilizer 16 , the wind power generator 22 and the solar power generator 7 will be described as follows.

The blower generator 42 may include a blower generator switch 144 and a fan 142 connected to the blower generator switch 144 . The blower generation switching unit 144 operates based on the flow rate of the air passing through the air purification passage F1 in the wind speed sensor 46 . When the flow rate is a speed at which wind power generation is possible, the fan 142 rotates by the flow of the atmosphere, and wind power generation is generated by the rotation of the fan 142 . If the flow rate is not a speed at which wind power generation is possible, the blower generation switching unit 144 rotates the fan so that the fan 142 also operates the blower. Preferably, the size and number of fans are appropriately arranged according to the size of the air purification passage F1.

A typical wind power generation starts rotation when the wind speed is 2.5 m/s or more, and produces electricity when it is 3.5 ~ 4.0 m/s, and produces 100% of electricity when it is 13 m/s or more. In addition, if the wind speed is 25 m/s or more, the wind power generation is stopped for safety. When the wind speed is converted to speed, power is produced when the speed is 15 km/h or more, 100% of the power is produced when the speed is 50 km/h or more. However, the calculation of the wind speed when the air purification apparatus according to the present embodiment is installed in a vehicle such as a running bus is as follows. The air purification device according to the present embodiment has a small cross-sectional area, so considering the case of a bus running at a speed of 100 km/h or less, there is almost no compressive effect of air, and it is calculated that the speed of the vehicle is almost the wind speed. However, since the speed limit for vehicles other than highways is 100 km/h or less, it can be seen that wind power generation is possible if an air purification device is installed in the vehicle.

The sterilization unit 16 is preferably a plasma sterilization device, and more preferably a photo plasma sterilization device. Plasma includes high-temperature plasma and low-temperature plasma. Low-temperature plasma has a characteristic that the temperature is as low as 150 degrees from room temperature, so it is already applied to sterilization. In addition, photo plasma emits strong enough light energy to destroy and sterilize harmful chemicals, bacteria, and ultrafine dust. Since the sterilization apparatus using plasma has already been widely used, a detailed description thereof will be omitted.

Since the wind power generation unit 22 and the solar power generation unit 7 are already used, a detailed description thereof will be omitted. However, as shown in FIG. 3 , the wind power generation unit 22 and the solar power generation unit 7 may be installed with a plurality of those having small fans according to the size of the first housing 32 . In addition, a fan or the like can be appropriately installed on the predetermined support members 146 and 146a. However, it is preferable that the support members 146 and 146a be as small as possible so as not to obstruct the flow of the air flowing through the air purification passage F1.

On the other hand, as described above, in this embodiment, when the air purification device is installed in a vehicle and the vehicle runs at a speed of about 15 - 100 km/h, wind power generation is possible.

Referring to FIG. 10, the configuration of the control device 54 of the air purification apparatus according to the present embodiment will be described as follows.

A first pollution level sensor 43 , a second pollution level sensor 44 and a wind speed sensor 46 are connected to the control unit 540 . In addition, the control unit 540 includes a first filter unit control unit 12D, a blower generator control unit 42D, a sterilizer control unit 16D, a second filter unit control unit 2D, a wind power generator control unit ( 22D), a dust separation unit control unit 24D, and a blower fan control unit 28D for a dust separation unit, respectively. Also, a communication unit TD is connected to the control unit 540 . The communication unit (TD) is preferably capable of communicating with the server (CS) of the pollution control integrated management center through the communication network (N).

Here, each control unit, communication unit, etc. are classified for convenience in terms of functionality for convenience of description, and are not necessarily separated concepts in terms of hardware and software, and may be implemented as a plurality of modular units in one software or one software, , may also be implemented in a suitable combination of hardware or software.

2 and 3, the operation of the air purification apparatus according to the present embodiment will be described as follows.

The air containing pollutants such as dust flows into the air purification passage F1. Dust contained in the introduced air is filtered by the first filter unit 12 . The air that has passed through the first filter unit 12 passes through the blower generator 42 . If it is determined that the wind speed of the air is a wind speed at which wind power generation is possible, the control unit 540 of the control device 54 controls the blower generator 42 to the blower generator control unit 42D to be a wind power generator. That is, the wind power generation switching unit 144 is controlled in the wind power generation mode. In this case, the fan 142 rotates by the air flow rate, and electricity generated by the rotation of the fan 142 is stored in the storage battery 52 . If it is determined that the wind speed of the air is not the wind speed at which wind power generation is possible, the control unit 540 of the control device 54 controls the blower generator 42 to function as a blower in the blower generator control unit 42D. . That is, the blower generation switching unit 144 is controlled in the blowing mode. In this case, the fan 142 rotates to create a flow rate so that the air can be sucked into the air purification passage F1. However, as described above, the air purification device 1 is installed in a vehicle, and wind power generation is generally possible while the vehicle is running.

The air passing through the first filter unit 12 is directed to the sterilization unit 16 . Bacteria and the like contained in the air are sterilized by the sterilization unit 16 . The air that has passed through the sterilization unit 16 passes through the second filter unit 2 . In the second filter unit 2 , dust is electrostatically collected. The air passing through the second filter unit 20 is directed to the wind power generation unit 22 . The air finally generates electricity in the wind power generator 22 and goes out of the air purification passage F1.

On the other hand, when the ozone measured by the second pollution level sensor 44 exceeds a predetermined positive value, the control unit 540 may stop the operation of the sterilization unit 16 and/or the second filter unit 2 . This is because ozone may be generated during the operation of the sterilizer 16 .

A process of collecting dust attached to the first filter unit 12 and the second filter unit 2 in the dust box 26 will be described.

A first filter cleaning unit 66 is positioned inside the filter of the first filter unit 12 . The first filter cleaning unit 66 sprays compressed air to the filter of the first filter unit 12 . Accordingly, dust adhering to the filter is separated from the filter. However, since compressed air is sprayed in the direction of the opening 322 between the air purification passage F1 and the dust collection passage F2, the separated dust flows into the dust collection passage F2. And, since the first filter unit 12 rotates at a predetermined speed, the dust attached to the filter of the first filter unit 12 is sequentially separated and flows into the dust collection passage F2. The dust attached to the suction pin 230 of the electrostatic suction unit 20 of the second filter unit 2 is also separated in the same principle as the first filter unit 12 and flows into the dust collection passage F2.

The dust separated by the first filter unit 12 and the second filter unit 20 and entered into the dust collection passage F2 is placed in a dust box by the dust separation unit 24 provided in the dust collection passage F2. 26) will come together. When dust accumulates in the dust box 26 by a predetermined amount or more, the dust box 26 is opened to throw away the dust.

The air purification effect of the air purification apparatus according to the present embodiment will be described as follows.

Install the air purification system on the bus and explain it based on the city of Seoul. The area of Seoul is approximately 605 km2, and the amount of air at a height of 3 m or less is 1,800,000,000 m2. Assuming that the cross-sectional area of the air purification channel of the air purifier is approximately 0.5 m2 (assuming the air purifying channel of the air purifier is 1200mm * 400mm) and the bus runs 200km per day, it purifies the air of 100,000m2. can do. In other words, if an air purification device is installed on 18,000 buses, the air in Seoul can be purified. However, since approximately 9,000 buses currently run, even if the air purifier according to the present invention is installed only on the currently running buses, it is possible to purify the air of about half of Seoul.

In addition, according to the present invention, when the pollution level of the air is transmitted from the pollution level sensor of the air purification device installed in each bus to the air pollution integrated management center, there is an advantage that the pollution level of each area can be more accurately identified and managed.

In addition, as described above, in the air purification apparatus according to the present invention, electric energy can be produced by the blower generator, the wind power generator, and the solar power generator. However, the biggest problem of the current electric vehicle is a long charging time and a small number of charging stations. That is, charging of electric vehicles is one of the biggest problems of current electric vehicles. Therefore, if the air purification device according to the present invention is installed in an electric vehicle and the electric energy produced by the air purification device is used to charge the electric vehicle, there is an advantage that the charging problem of the electric vehicle can be solved to some extent. In other words, if an air purification device is installed in an electric vehicle, the electricity produced by the air purification device can be used as energy for the electric vehicle and at the same time dust can be removed.

Meanwhile, in the above-described embodiment, it has been described that the air purification device is installed in a vehicle such as a bus or subway, but the present invention is not limited thereto. For example, the air purification device may be installed on the roof of a building, a tunnel, or the like.

As described above, the present invention has been described with reference to limited embodiments and drawings having specific details such as specific components, but these are used to help the understanding of the present invention. That is, the present invention is not limited to the embodiments described above, and various modifications and variations are possible from these descriptions by those of ordinary skill in the art to which the present invention pertains, and these modifications and variations are the scope of the present invention.
