摘　　要：气液旋流分离器工作时,两相混合物从入口管切向进入圆柱形筒体开始分离。所以当入口管和筒体的结构发生变化时,对整个旋流分离带来的影响是直接的。旋流分离之后的气相,是经过溢流管离开体系的,因此当溢流管的结构改变时,气相的最终分离也会受到影响。从溢流管的半径、插入深度、筒体的半径与高度四个方面出发进行数值模拟,每个影响因子设计了六组平行的仿真模拟实验。In operation of the gas-liquid cyclone separator, the two-phase mixture tangentially enters the cylindrical barrel from the inlet tube and begins to be separated. Therefore, the changes of the structure of the inlet pipe and the cylinder changes will directly affect the final separation of the gas phase. The gas phase separated by the cyclone separator exits the system through the overflow tube. Therefore, the structure of the overflow pipe is the key factor affected the final separation of the gas phase. In this paper,numerical simulation is carried out from four aspects: the radius of the overflow pipe, the insertion depth,the radius and height of the cylinder. Six sets of parallel simulation experiments were designed for each impact factor.
