摘　　要：针对某选煤厂筛分车间的除尘管道,根据流体动力学原理和气-固两相流理论,结合现场实测的数据,建立了模拟粉尘沉降运动规律的数学模型,并应用FLUENT软件对该选煤厂筛分车间水平除尘管道内不同粒径的粉尘沉降规律进行数值模拟,得出了粉尘的沉降轨迹,从而为提高筛分车间除尘系统效率提供了理论依据。This thesis make a study on the coal preparation plant dust screening pipeline,according to fluid dynamics and phase flow theory and the test data,set up the Simulation model of dust settlement movement discipline,and applicated FLUENT software set up simulation of different sizes dust settlement movement discipline of Coal Preparation plant＇s horizontal pipe section,Finally get the Dust settlement track in the three pipe sections,provided important theoretical basis to enhance dust collection efficiency.
