- the crane 10 has a structure in which a plurality of boom bars having different diameters are sequentially connected so that the overall length can be extended or contracted, and configured to sequentially receive a boom having a small diameter into a boom having a large diameter. It is desirable. So, when all the booms are elongated, the crane 10 has a maximum height of 40 to 60 m, preferably 50 to 55 m.
- each boom constituting the crane 10 is about 7m, so that the height of the crane 10 contracts to about 10m when all the booms are housed in the lowest boom having the largest diameter. desirable.
- the sprinkling nozzle 20 sprays water droplets particles W from the top of the crane 10, and the spray height of the water droplets W is the lower end of the crane 10, that is, 80 to 130 m from the ground. Spray to reach the height of.
- the height of water spraying of the sprinkling nozzle 20 may be 30 to 80m from the top of the crane 10.
- the spraying height of the water droplets particles (W) is less than 80m from the bottom of the crane 10, the effect of removing fine dust is insufficient.
- it exceeds 130m the increase in the effect due to the increase in operating cost is insignificant and inefficient to be.
- the water supply means 30 may include, for example, a storage tank 31 and a high pressure pump 32, a transfer hose 33, and a hose drum 34.
- the storage tank 31 is a place to store water sprayed through the sprinkling nozzle 20, that is, water for sprinkling, and is installed near the lower end of the crane 10, and a water level control valve is installed to maintain a constant water level.
- the high pressure pump 32 is installed next to the water storage tank 31 and serves to provide water pressure so that the watering water stored in the water storage tank 31 is sprayed through the watering nozzle 20.

- control unit 40 the extension and angle of the crane 10, the spraying angle and the spraying distance of the sprinkling nozzle 20, the high pressure pump 32 and the hose drum 34 of the water supply means (30) It functions to control each light.
- the crane 10 when the crane 10 is continuously installed, it is possible to construct a system for integrated operation for each unit group by separating it into several unit groups.
- the crane 10 is preferably installed side by side with an interval of 30 to 60m in the bridge or riverside.
- the crane 10 is installed on a bridge or riverside, it is easy to secure water for sprinkling supplied to the sprinkling nozzle 20, and the water discharged from the sprinkling nozzle 20 can be sent back to the river, There is also a side effect of purifying river water.
- the crane 10 can adjust the height, angle and rotation while the lower part is fixed, the geographical condition of the place where the crane 10 is installed, the wind direction and wind speed at the time of operating the system of the present invention, etc. In consideration of this, it can be easily adjusted so that the water discharged from the sprinkling nozzle 20 falls back into the river.
- the crane 10 sprays water droplets (W) in the opposite direction from which the wind blows, while the crane 10 is erected at an angle of 70 to 85 degrees in the opposite direction from which the wind blows. If water is sprayed in the direction of the wind blowing, the water discharged from the sprinkling nozzle 20 falls on the water supply means 30 and the control unit 40 installed at the bottom of the crane 10, as well as water droplets. This is because the width of the artificial water wall formed by (W) can be narrowed.

- the spray nozzle 20 is preferably composed of 2 to 4 nozzles having different spray angles and spray distances of the water droplets. As shown in Fig. 2, under the condition that the spray pressure of each spray nozzle is the same, the spray distance of the water droplets is inversely proportional to the spray angle. That is, when the spraying angle is increased, the spraying distance is shortened, and when the spraying distance is decreased, the spraying distance becomes longer.
- the sprinkling nozzle 20 is composed of three, and the droplet particles W sprayed from the sprinkling nozzle 20 freely fall to form a continuous artificial water wall having a width of 30 to 60 m. It is desirable to configure it to be. If the width of the artificial water wall is less than 30m, the effect of removing fine dust may decrease, and if it exceeds 60m, the operation cost may increase.
- an air jet for injecting compressed air may be additionally installed at the upper end of the crane 10.
- the air jet functions to form an effective artificial water wall by spraying the water droplet particles W sprayed from the sprinkling nozzle 20 in a desired direction according to the wind direction and region.
- Diameter(cm) 0.5 0.3 0.2 0.1 0.05 0.02 Number of water droplets 570,240 950,400 1,425,600 2,851,200 5,702,400 14,256,000 Reference downpour shower Moderate rain Weak rain
- the distribution of water droplets W having a diameter of 0.02 to 0.3 cm among the water droplets W sprayed through the sprinkling nozzle 20 is preferable to configure the distribution of water droplets W having a diameter of 0.02 to 0.3 cm among the water droplets W sprayed through the sprinkling nozzle 20 to be 80% or more.
- a noise prevention cap it is possible to attach and detach a noise prevention cap to the sprinkling nozzle 20. It can also be installed.
- fine dust In general, fine dust is very fine and light, so it settles in the atmosphere at a very slow rate. As a result of theoretically calculating the sedimentation speed of fine dust in the absence of wind using the Stock law, fine dust with a particle size of 2.5 PM settles at a speed of 0.82 m per hour, and fine dust with a particle size of 10 PM is It was found to settle at a rate of 13.1 m per hour.
