摘要：

Internal flow field of dust collector for a street vacuum is studied by Computational Fluid Dynamics (CFD). The causes of uneven distribution of flow field were diagnosed by simulation, and an improvement measure was put forward. The result shows that flow ratce distribution of dust collector is uneven, the reason for which is the higher wind velocity at the Inlet. A baffle plate was added at the Inlet to improve the uniformity of internal flow field. The main technical parameters, maximum flow rate uneven amplitude Delta k(i) and overall flow rate uneven amplitude Delta(k) over bar (i) and overall flow rate uneven amplitude, are decreased in this way Delta k(i) is reduced from 0.3429 to 0.1308. While Delta(k) over bar (i) is reduced from 0.1012 to 0.0402.
