3 is a conceptual diagram illustrating a water supply unit and a control unit of an apparatus for reducing fine dust using a transmission structure according to an embodiment of the present invention.

2 and 3, the water supply unit 10 according to an embodiment of the present invention includes a storage tank 11, a supply pump 12, and a water level maintenance device 13.

The storage tank 11 is a device that stores water, receives water from a water source, stores it at a water level within a set range, and is connected to the water curtain part 20 by a pipe. The supply pump 12 is a device for forcibly transferring the water stored in the storage tank 11 to the transmission structure 2, and when the supply pump 12 is operated, the water stored in the storage tank 11 goes through a pipe and It is transferred to the part 20 and is sprayed to the outside of the water curtain part 20 while flowing along the water curtain part 20 having a hose structure.

The water level maintenance device 13 is a device for maintaining the water level of the storage tank 11 in a set range, and the water spray operation of the present invention according to the fine dust concentration is reliably performed by maintaining the water level of the storage tank 11 constant. Make it possible. That is, by always storing and maintaining a set amount of water in the storage tank 11, it is possible to quickly and smoothly supply water to the water curtain unit 20 when the fine dust concentration is poor. Referring to FIGS. 2 and 3, a water level maintenance device 13 according to an embodiment of the present invention includes a water level sensor 14, a water level notification device 15, and a water replenishment controller 16.

The water level sensor 14 measures the level of water stored in the storage tank 11 in real time. The water level notification device 15 generates a signal when the water level measured by the water level sensor 14 is less than the water level within the set range. The water replenishment controller 16 receives a signal from the water level notification device 15 and operates a storage pump 17 that transfers water from the water source to the water level sensor 14, or supplies water installed on a pipe connected to the water source. Open the valve (not shown).

When the water level sensor 14 measures the water level below the set range, a signal is input to the water replenishment controller 16, and the water replenishment controller 16 operates the storage pump 17 or supplies water.

It is a conceptual diagram illustrating various embodiments of the water outlet, and FIG. 6 is a conceptual diagram illustrating other various embodiments of the water outlet of the apparatus for reducing fine dust using a transmission structure according to an embodiment of the present invention.

2 and 4, the water curtain part 20 according to an embodiment of the present invention includes a water spray pipe 21 and a water spray device 22.

The water spray pipe 21 has a structure of a hose capable of continuously transporting water and is disposed between the transmission structures 2, and one side and the other side in the extension direction are respectively coupled to the plurality of transmission structures 2. More specifically, one side of the water spray pipe 21 in the extending direction is coupled to the first transmission structure 2A, and the other side is coupled to the second transmission structure 2A spaced apart from the first transmission structure 2A. Accordingly, the water spray pipe 21 is continuously disposed between the plurality of transmission structures 2 and is disposed to extend horizontally in the air spaced from the ground.

The water spray device 22 is a device for discharging water to the outside of the water spray pipe 21, and has a water outlet 23 and a plurality of water spray devices 22 are disposed along the longitudinal direction of the water spray pipe 21. In arranging the plurality of water spraying devices 22 along the longitudinal direction of the water spraying pipe 21, as shown in FIG. 4, the width of the water spraying device 22 increases as the water spraying device 22 moves away from the water supply unit 10, It is desirable to have an area.

2, the water supply unit 10 is disposed under the first transmission structure 2A among the plurality of transmission structures 2, and raises water to the water spray pipe 21 on the upper side along the first transmission structure 2A. Supply. At this time, the water pressure at the portion A closest to the first transmission structure 2A among the water spray pipes 21 is the strongest, and the water pressure gradually decreases in the order of the A portion and the neighboring B portion, and the B portion and the neighboring C portion. .

In the case of forming the water spray device 22 with the same width and area over the entire length of the water spray pipe 21, the water pressure inside the water spray pipe 21 decreases as described above as the distance from the water supply unit 10 decreases, The amount of water discharged and sprayed to the outside of the device 22 is reduced. As in the exemplary embodiment of the present invention, if the water dispensing device 22 has an enlarged width and area as it moves away from the water supply unit 10, water discharge is made to a more uniform degree over the entire length of the water spray pipe 21. I can.

The water spraying device 22 according to an embodiment of the present invention has a structure in which a plurality of water outlets 23 are disposed to be spaced apart. Since the area where the water outlet 23 is disposed among the water spraying devices 22 can be interpreted as an effective area of the water spraying device 22 in which water is substantially discharged, in the description of the present invention, the area where the water outlet 23 is disposed It is assumed that the width of is the width of the water spray device 22.

Accordingly, the total width and area of the water spray device 22 are determined according to the number and width of the water outlets 23. That is, the water spraying device 22 has a structure in which the number of water outlets 23 increases or the width of the water spraying device 22 increases as the distance from the water supply unit 10 increases. In arranging a plurality of water outlets 23 having the same width in the water spraying device 22, the number of water outlets 23 is configured differently as shown in FIGS. 5A and 5B, The width and area of each of the water spraying devices 22 may be differentiated.

In addition, in arranging a plurality of water outlets 23 having the same number in the water spraying device 22, the width of the water outlet 23 is configured differently as shown in FIGS. 6A and 6B. By doing so, it is possible to differentiate the width and area of each of the water spray devices 22.

The water outlet 23 preferably has a circular cross-sectional shape and a radius of 0.1 mm or less in order to induce a radius r of water droplets sprayed through the water outlet 23 to be 0.1 mm or less.

7 is a graph of the final velocity according to the radius of the water droplet.

The amount of fine dust removed is proportional to the surface area of the water droplets discharged through the water outlet 23 and the time the water droplets stay in the air. The surface area per unit volume of a droplet can be summarized as 4πr ² /(3/4×πr ³ ) by using the radius (r) of the droplet as a parameter. It is inversely proportional. That is, the smaller the radius r of the droplet, the larger the surface area per unit volume of the droplet.

According to the following Navier-Stokes equation, the final drop velocity (u _∞ ) of a droplet is reached when the attraction applied to the droplet in the surrounding air is similar to gravity. Where ug is the acceleration due to gravity, ρl is the density of water, C _D is the attractive force coefficient, Is the Reynolds number, ρ is the density of the liquid, and ν is the viscosity of the air movement.

In addition, when the radius of the droplet (r) <30㎛, according to the drop analysis equation below, the final drop velocity (u _∞ ) of the droplet is proportional to the radius of the droplet (r ² ).

In addition, when 40㎛<radius of water droplet (r)<600㎛, according to the drop analysis equation below, the final drop velocity (u _∞ ) is proportional to the radius (r) of the water droplet.

That is, according to Equations 1 and 2, the smaller the droplet, the lower the final falling speed (u _∞ ) of the droplet and the time to stay in the air increases.

In addition, according to the terminal velocity graph according to the radius (r) of the water droplet shown in FIG. 7, it can be confirmed that the speed of the water droplet increases rapidly when the radius (r) of the water droplet exceeds 0.1 mm. have. That is, according to the above equations and graphs, it is confirmed that the falling speed of the water droplet when the radius (r) of the water droplet is less than 0.1 mm is significantly lower than that when the radius (r) of the water droplet exceeds 0.1 mm. I can.

The larger the surface area of the entire water droplet sprayed from the water spraying device 22, that is, the larger the surface area per unit volume of the water droplet, and the slower the falling speed of the water droplet, the higher the adsorption rate between the water droplet and the fine dust, thereby improving the efficiency of removing fine dust. In the present invention, the water outlet 23 is formed with a radius r of 0.1 mm or less as described above, so that the radius r of the water droplet discharged through the water outlet 23 is 0.1 mm or less. By inducing, the above action can be implemented.

As shown in FIGS. 5 and 6, a plurality of water outlets 23 having the same diameter may be disposed, but as shown in FIG. 4, a plurality of water outlets 23 having different diameters may be mixed and disposed. 4, the water outlet 23 according to an embodiment of the present invention includes a plurality of first discharge holes 24 and second discharge holes 25 having different radii.

By arranging the first discharge hole 24 and the second discharge hole 25 having a larger radius than the first discharge hole 24 on one water spraying device 22, more specifically, the first discharge hole (24) By disposing the second discharge hole 25 at a uniform density, water is discharged through the second discharge hole 25 even if the first discharge hole 24 is blocked as water freezes due to winter freezing. Can be done.

I can.

The operation control unit 34 outputs a control command for operating the water supply unit 10 when the information processing unit 33 determines that the fine dust concentration exceeds the reference value, that is, when the fine dust is recognized as bad or very bad. In addition, when the information processing unit 33 determines that the fine dust concentration is less than the reference value, that is, when the fine dust is recognized as normal or good, a control command for stopping the operation of the water supply unit 10 is output. As the operation control unit 34, a mobile web may be applied.

When the fine dust concentration measured by the fine dust sensor 32 and input to the information processing unit 33 is greater than or equal to the reference value indicating bad, the operation control unit 34 outputs a control command to operate the supply pump 12, and the supply pump By the drive of (12), the water inside the storage tank 11 is transferred to the water curtain part 20, and is discharged through the water spraying device 22 while flowing along the water spray pipe 21, as shown in FIG.
