Large open field is often due to the action of wind coal, causing serious environmental pollution around, open-air coal field to take scientific measures to solve this problem building coal yard Wind Dust Network, both locked the scattering ash pollution of the environment, but also effectively reduce the loss. The so-called coal yard Wind Dust Network, also known as wind and dust wall, the wall surface mesh to take treatment, the use of low-carbon steel, galvanized sheet, color coated steel plate, aluminum-magnesium alloy plate, stainless steel as the material, mainly for coal mines, coking plants, power plants and other storage coal plants Wind Dust. Open Coal Yard Wind Dust Network 15 meters high, with a total investment of 6.5 million yuan, the use of aerodynamics, so that the flow of air from the outside through the wall on the inside of the wall is formed under the interference of the airflow to reach the outside strong winds, the wind side of the weak wind; the outside of a small wind, no wind, the effect of the inside, to prevent dust emissions.
