Wetting agent spray dust reduction technology and experiment

Based on aerodynamics and hydrodynamics theories, this study improves dust suppression efficiency by optimizing water spray parameters and adding humectant. The characteristics of different atomization methods were systematically investigated, and the optimal combination of spray parameters was determined. Sodium dodecylbenzene sulfonate was selected as the humectant to enhance the dust capture capacity of droplets. Experimental results show that adding 0.2%–0.6% sodium dodecylbenzene sulfonate can significantly improve the wettability of the solution and has a notable effect on removing fine dust and total dust.
