目的 研究外加离子风风场对粉体充填过程粉尘落袋的影响，探究离子风机应用于粉体除静电包装的可行性。方法 基于气固耦合机理，利用Fluent软件，使用k-ω湍流模型与离散相模型（DPM），模拟外加风场情况下粉体包装的粉尘落袋过程，分析离子风风速对不同粒径粉尘颗粒捕获率的影响。结果 模拟结果显示，在外加离子风风场风速≤0.4 m/s时，风场对粉尘颗粒捕获率影响较小，在风速为0.4~ 0.6 m/s时，对直径1~30 µm的粉尘颗粒的捕获率有明显的提升作用。结论 通过设置适当的离子风风速，外加风场不会加剧粉体充填过程中出现的扬尘，在粉体填充包装过程中使用离子风机消除静电是可 行的。

The work aims to study the effect of ionic wind field on dust bagging in powder filling process, and to explore the feasibility of ionic fan applied in powder electrostatic packaging. Based on the mechanism of gas-solid coupling, the dust bagging of powder packaging was simulated by the k-ω turbulence model and the discrete phase model (DPM) through Fluent software, and the effects of different ion wind speed on the capture rate of dust particles in different particle sizes were analyzed. The simulation results showed that when the wind speed of the applied ionic wind field was ≤0.4 m/s, the influence of the applied wind field on the dust particle capture rate was small. When the wind speed was in the range of 0.4 m/s-0.6 m/s, the capture rate of dust particle with particle diameter of 1 micron to 30 micron was obviously increased. Setting appropriate ion wind speed will not aggravate the dust in the powder filling. It is feasible to use ion blower to eliminate static electricity in the powder filling and packaging.
