Dustproof mechanism

The mechanism of steel windbreak is directly related to mechanism of emission, drift, diffusion and deposition of dust in bulk yard. The main mechanism is that the steel windbreak can control or modify the airflow, reduce the wind speed and turbulent velocity on bulk yard. When the strong wind is coming, only part of it can go through the windbreak network. Its mechanical energy is decayed and turns into low speed airflow. At the same time, the large-scale, high-intensity vortex of wind in front of the windbreak is reduced and combed into small-scale and weak intensity vortex. The low speed and low turbulent velocity wind that flow-sweeps the bulk yard becomes a low speed gradient, low speed curl, weak vorticity and low turbulence airflow in the bulk yard, which make dust from the lower field drastically reduced.

 

By means of aerodynamics laboratory study and field measurement, we analyze the changes of pressure, flowing direction of air through solid walls and net walls in view to reveal the theory of windbreak and dust suppression wall system by comparison of data. 

When building the masonry wall to prevent the wind, the opening rate of wall is zero.When Pa> Pb, Pc> Pd, in area A and B, low pressure areas are formed. Wind goes down deflection and forms a vortex area at the back of storage pile in area B which uptakes dust.

When windbreak wall is used, such wall has some open holes; wind can go through the wall. In area A, because Pa = Pb and V2 ≤ V1 / 2, the probability of wind speed exceeding critical dust arouse is declined. In area B, the airflow goes through the net wall and will not rebound, form wind vortex or produce strong turbulence and vertical turbulence, but will reduce the airflow effect on dust during production operations , and thus weaken or avoid dust uptake.
