摘　　要：为了提高水力旋流器的分离精度和效率,在水力旋流器内部增加中心锥以强化旋流器中的颗粒在柱段内的离心沉降。以水力旋流器内部流场分离精度为目标,分析中心锥对水力旋流器流场的控制效果,采用激光粒度分析仪和化学滴定方法测得电石渣的物料特性,通过最大切线速度轨迹面分离粒度数学模型计算出旋流器的结构参数。利用Solidwords软件建立水力旋流器的3D模型,并通过计算流体动力学(CFD)软件模拟电石渣浆液的分离过程,从压力、速度、湍流、速度矢量和质量流5个方面进行仿真。仿真结果表明,增加中心锥对提高水力旋流器的分离精度具有一定的效果。In order to improve the separation precision of hydrocyclone,the increase of center cone in the interior of the hydrocyclone can strengthen centrifugal sedimentation of particles within the column section in the hydrocyclone. The influence of central cone on the flow field of hydrocyclone was studied using the inner flow field of hydrocyclone,material characteristics of carbide slag were measured with laser particle size analyzer and chemical titration method,and the structural parameters of the hydrocyclone were calculated through the maximum tangential velocity track surface separation size mathematical model. 3D model of the hydrocyclone was established based on Solidworks software,and the separation process of carbide slag slurry was simulated with the computational fluid dynamics（ CFD） software,in aspects of pressure,velocity,turbulence,velocity vector and mass flow rate. According to the simulation results,the increase of center cone can improve separation accuracy of the hydrocycloe.
