Abstract：Aiming at the problem of high concentration and difficult control of dust in loading station,a new type of soft seal dust control system was proposed.The airflow structure and dust mass concentration distribution characteristics of the flow field under the new ventilation system were explored by numerical simulation method and compared with the traditional ventilation system.The simulation results show that the vortex field with controllable range of action and airflow intensity can be generated by providing updraft in the roof of the flow field and providing induced swirl with horizontal shear force around it.Compared with the traditional ventilation system,the soft seal dust control system effectively brings down the static pressure in the central region of the flow field,and produces a large pressure difference between the central region of the flow field and the outer space of the flow field.The axial capture distance of dust is almost doubled,and the long-distance capture of dust is better realized.According to the test,the dust concentration was reduced from 107.14 mg/m3 to 20.81 mg/m3 under the soft sealing dust control system,indicating that the ventilation system can effectively capture and control the unorganized dust emission.
