  • In order to improve dust collection efficiency, the computational fluid dynamics (CFD) technology was used to calculate the flow field of reverse blowing pickup mouth, analyze the structural parameters influence on the dust collection efficiency, and calculate the dust collection efficiency combined with the gas-solid flow model. The results show that when the ratio between outlet diameter and width is less than 0.47 and the dip angle is less than 105,the dust collection efficiency can improved by increasing the outlet diameter and dip angle.Airflow velocity is high and the direction is close to the ground when reverse blowing pickup mouth is near the ground. There is no leakage to bring about secondary pollution. The overall removal efficiency declines by 27%when traveling speed increases from 5 km/h to 15 km/h, in which the grade efficiency of 45 and 152 m particle diameter respectively decrease by 9%and 33%.
