Comparison of Dust Suppression Effects of Coal Wharf under Different Dust Generation Parameters

Abstract

Taking an open-air coal yard as an example, comparing the effects of different setting methods of the windbreak net on the dust formation in the open-air yard, the results show that when the windproof net is of “mouth” type, the effect of dust suppression and windproof is the best; when the windproof net is in “L” shape, the dust suppression effect is the worst. Comparing the dust suppression effect of the windscreen under different dusting parameters, it is obtained that while optimizing the plane parameters, height and opening rate, the influence of moisture content on the dust suppression effect of the windscreen also needs to be considered. The results show that when the moisture content when the dust suppression rate reaches 8%, the dust suppression rate can reach more than 85%, and the dust suppression effect is greatly improved.
