Analysis of the Influence of Ventilation Flow on Dust Removal Efficiency of Wet Dust Removal Fan

Wet dust removal fan has become the preferred dust removal equipment for mines, tunnels, and other excavation working faces for the advantages of small size, simple operation and high efficiency. The dust removal efficiency of the fan is often influenced by the tunnel ventilation. The key to improving the efficiency is how to adjust the volume between the mechanical ventilation and dust removal fan. In this paper, the dust removal efficiency under different suction ratios were analyzed by numerical simulation and field experiments, and suggestions on the optimal suction ratios of the excavation working faces were given, which can provide reference for similar projects.
