The windproof and dust suppression net utilizes the principle of aerodynamics to process windshields with a certain geometric shape according to the results of field environmental wind tunnel experiments. ) when passing through the wall from the outside, the upper and lower interference airflows are formed on the inside of the wall to achieve the effect of strong wind on the outside and weak wind on the wind side; small wind on the outside and no wind on the inside, thereby preventing dust from flying.

In the design of this technology, wind tunnel effect testing was carried out on a variety of windshield and dust suppression panels with different shapes and opening ratios. The results show that the butterfly windshield can significantly reduce the wind speed and wind force under a certain opening ratio. 

Design of the wind and dust suppression wall When the air flow passes through each wind and dust suppression board, the air flow will pass through the openings of the wind protection board. There are two phenomena of separation and attachment behind the windshield. Simultaneously, there are up and down disturbing air flow, which reduces the wind speed of the incoming flow and loses the kinetic energy of the incoming air. At the same time, it avoids the vortex of the air flow in front of the windshield and reduces the turbulence of the incoming air; this reduces the shear stress and pressure on the surface of the material pile, thereby reducing the dust of the material.
The incoming wind passing through the windshield will form turbulent and vortex airflow, but at this time, the wind speed and wind pressure attenuation are relatively large, which is proportional to the wind speed n times. Therefore, the greater the wind speed, the higher the suppression and dust suppression efficiency of the windproof and dust suppression net in the material yard, and the better the effect of controlling dust.
