摘　　要：对喷流除尘技术在收集高湿高黏性粉尘的应用中具有独特优势。不同于大多数研究都是通过优化工况参数来提高除尘效率,而是从除尘器的结构考虑,应用有限元分析软件ANSYS中的FLOTRAN模块对其内部的流场进行仿真,得到了速度矢量场分布。根据仿真结果,对除尘器的结构进行了优化设计,使其结构能够满足最有利于提高除尘效率的流场分布。通过实际试验得到的最优除尘条件与通过数值模拟得到的优化参数是基本一致的,因此应用数值模拟方法得到速度矢量场从而优化除尘器结构参数的方法是可行的。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 nu- merical simulation. Therefore, it is feasible to optimize the parameters of a duster structure by the velocity vector field obtained by numerical simulation.
