To this end, the dust reduction system comprises: at least one vertical structure; a transfer part for transferring water to an upper portion of the vertical structure; and a water jet part for removing dust by forming a water curtain on an inflow path through which dust is introduced by jetting water transferred to the upper portion of the vertical structure in at least one direction around the vertical structure.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a dust-

The present invention relates to a system for reducing yellow sand or fine dust.

Dust occurs in the loess zone of sedimentary sand and mud, and occurs predominantly in dry desert regions such as sandstorms. Sand or dust particles float into the air due to strong winds, float up to the upper atmosphere and move away in an air stream. These dusts mainly occur in desertified areas of China or Mongolia, and adversely affect not only China and Mongolia but also Korea and Japan, all over Northeast Asia.

In particular, dusts from China and Mongolia often flow into Korea through the Yellow Sea accompanied by fine dust (including heavy metals). These dusts, accompanied by fine dust, are combined with the water vapor of the Yellow Sea, As it flows into Korea, it not only induces diseases of human respiratory system but also increases defective products in precision industries such as semiconductors.

According to a report by the Organization for Economic Cooperation and Development (OECD), Korea's air pollution caused by dust and fine dust is the worst among OECD member countries, and it is estimated that Korea's social costs will exceed 10 trillion won annually. In 2060, Korea's annual GDP loss ratio is expected to be the largest among the OECD member countries with a loss ratio of about 0.63%, reaching about 22.45 trillion won based on the current exchange rate at 500 dollars per person.

As a method to suppress the occurrence of yellow dust, the desertification area in China or Mongolia has been created, but the effect is very minimal and there is no fundamental solution yet. As an example of conventional techniques for reducing yellow dust and fine dust, an air purifier of Korean Patent Laid-Open No. 10-2016-0088699 is taken as an example. Conventional air purifiers include a yellow filter for filtering yellow dust or fine dust introduced into a room, As shown in FIG. However, the HEPA filter of such an air cleaner is mainly for purifying the indoor air, and there is a limit in reducing large-scale dustiness or fine dust in a certain outdoor area.

Accordingly, it is possible to effectively prevent the yellow dust or fine dust moving along the air stream from entering a certain area of the outdoor space while gradually falling down in combination with the water vapor of the seawater, thereby effectively preventing airborne concentrations of yellow dust or fine dust in a certain outdoor area It is urgently necessary to develop a system capable of reducing the amount of waste.

The water flows into the vertical structure 20, At least one conveying pipe (21-1, 21-2, 21-3); A filter 22 installed at an inlet of the conveying pipes 21-1, 21-2 and 21-3 for filtering out foreign matter from the water; At least one transfer pump (P) for transferring the water in the transfer pipes (21-1, 21-2, 21-3) upward; And at least one intermediate tank (23-1, 23-2, 23) for temporarily storing the transferred water is determined in consideration of a limit height that can be transported upward by the transfer pump (P) -3). The feed pump (P) may be a special high pressure pump.

2, the water jetting unit 50 includes at least one water jetting unit 40 for jetting the water conveyed to the upper part of the vertical structure 20 by the conveying unit 40 in at least one direction around the vertical structure 20, (51-1, 51-2, 51-3); And a nozzle installed at each of the outlets of the spray tubes 51-1, 51-2 and 51-3.

At least one of the injection pipes 51-1, 51-2 and 51-3 may be disposed at an upper portion of the vertical structure 20 at different installation heights. As shown in FIG. 2, the vertical structure 20, Can be configured to have a longer length. According to the spray tubes 51-1, 51-2, and 51-3 configured as described above, a water curtain can be formed more uniformly in the inflow path of yellow dust or fine dust that flows in a certain direction on the airflow It is possible to effectively reduce the atmospheric concentration of yellow sand or fine dust more efficiently. However, the present invention is not limited thereto, and the spray tubes 51-1, 51-2, and 51-3 may be configured to have any length. The valve V may be provided in the injection pipes 51-1, 51-2 and 51-3. The opening and closing of the pipe may be controlled by opening and closing the pipe through the valve V so that the amount of water injected from the injection nozzle And spray angle can be adjusted.

4, the control unit 60 can collect information about the atmospheric concentration of yellow sand or fine dust in real time through the sensing sensor S located at the upper portion of the vertical structure 20, In addition, the weather server (WS) of the Korea Meteorological Administration can collect information on the occurrence of yellow dust in China, for example, and the estimated time of arrival of yellow dust or fine dust. The control unit 60 determines whether the dust reduction system 10 is operated by determining whether the dust transfer system P is operated and whether the valve V is closed or not based on various pieces of collected information . In addition, a surveillance camera MC for monitoring the normal operation of the dust reduction system 10 may be installed on the vertical structure 20. In addition, the control unit 60 can remotely control the operation of the dust reduction system 10 according to the present invention by wireless.

Referring to FIG. 4, the dust reduction system 10 according to the present invention may be installed at a plurality of locations spaced apart from each other by a predetermined distance. The control unit 60 collects information on the concentration of yellow dust or fine dust in the air in real time through the detection sensor S and detects the occurrence of yellow dust in China and the yellow dust or the like through the airflow through the meteorological server WS Information on the expected time of inflow of fine dust is collected, and based on this information, the operation of the dust reduction system 10 is determined.

The control unit 60 operates the dust removing system 10 so that the water of the sea or the river is discharged to the outside of the vertical structure 20 through the transfer unit 50 A water curtain can be formed in the inflow path through which yellow sand or fine dust flows in the air stream by jetting the water conveyed upward by the water jetting unit 50. [ As a result, yellow dust or fine dust moving along the air stream is combined with water vapor of the seawater and is gradually lowered to effectively block the inflow of the dust into a certain area of the outdoor space, thereby increasing the atmospheric concentration of yellow dust or fine dust in a certain outdoor area Can be reduced.
