Abstract To improve the dust removal efficiency of external spray negative-pressure mist-curtain dust suppression devices, a multi-factor orthogonal experiment was designed and a numerical simulation was carried out for these types of devices. According to changes in the measurement factor values in the simulation results, the main factors affecting the negative-pressure suction effect of the device were obtained through analysis and ranked in the order: Nozzle installation position > Angle of the conical cover > Length of the conical cover; the significant analysis results were FA
