摘　　要：针对内部增加中心柱对分离电石渣用水力旋流器流场的影响,分别开展了无中心柱和内部增加中心柱的静态水力旋流器的流场模拟。利用Fluent软件对加载电石渣浆液的两个水力旋流器模型进行数值模拟,分别从压力、切向速度、湍流强度和速度矢量四个方面进行分析。模拟结果表明,内部增加中心柱使旋流器的能量损失减少,旋流器内的流场更稳定,有利于提高旋流器的分离效率。搭建试验平台进行试验研究,验证增加中心柱的水力旋流器的可行性。For the effect of internal increased center column flow field of hydroclonc for separating carbide slag, separately to carry out the flow field simulation on static hydrocyclone of no center column and internal increased center column. Fluent was applied to simulate two hydroeycloue model with carbide slag slurry, analyzed from the pressure, tangential velocity, turbulence intensity and velocity vector. The simulation results showed that the center column reduces the energy loss, stabilizes the flow field inside the cyclone, helps to improve the separation efficiency of the hydrocyclone. Test platform was build to test and verify the feasibility of hydroclone for increasing center column.
