Abstract: Impinging stream dusting technology has its unique advantage in collecting dust of high humidity and high viscosity. Different from most researches in which the dusting efficiency is improved by optimizing the working conditions, this research addresses the issue from the duster's structure. FLOTRAN module in ANSYS, a finite element analysis software, is used to simulate the inside flow filed so as to get he velocity vector distribution. Based on the simulation result, the duster structure is optimized, enabling it to get a flow field distribution that is most beneficial to the improvement of dusting efficiency. The optimal dusting conditions obtained from the real test basically accord with the parameters optimized by numerical simulation. Therefore, it is feasible to optimize the parameters of a duster structure by the velocity vector field obtained by numerical simulation.
