A new type of nonpowered airflow dust removal device was designed and manufactured. The dust control mechanism was studied through numerical simulation and experimental study, and the influence of the length of the nonpowered airflow dust removal device and the belt speed of the conveyor on the dust removal effect was analysed. The results showed that the dust removal effect was positively correlated with the length of the dust removal device and the belt speed of the conveyor. To verify the dust control effect, the field application was carried out at Anhui Huayi Chemical Co., LTD, and an obvious dust control effect was obtained with the dust concentration reducing from 227.3 mg/m3 to 8.3 mg/m3. [Display omitted] •The dust control effect is improved with the increase of belt speed.•The dust control effect is positively correlated with the length of the device.•The dust control effect is related to negative pressure.•The negative pressure is generated by skirt structure of the device.•The device is not required power supply, environmental friendly.
