针对稠油掺稀降黏开采过程中稠油与稀油混合不均匀的问题,设计了一种新型混合器,采用一个涡轮式叶轮和折叶式叶轮组合的方式,并且通过键与轴连接,两个叶轮一起联动。采用FLUENT 6DOF模型,对混合器的混合效果进行了仿真分析,从叶轮旋转速度、稀油体积分数、涡旋性3个方面进行评价。结果表明,新型混合器虽然旋转速度有所下降,但是稀油分布更加均匀,具有更强的涡旋速度,说明新型混合器比现有混合器具有更好的混合效果。 Aiming at the non-uniform mixing of heavy oil and thin oil during the process of heavy oil desizing and visbreaking, a new type of mixer was designed. By using a combination of turbine impeller and hinged impeller, Two impeller linked together. Using the FLUENT 6DOF model, the mixing effect of the mixer was simulated and analyzed, including the impeller rotation speed, the volume fraction of dilute oil and the vorticity. The results show that the new mixer has lower rotational speed but more uniform distribution of thinner oil and stronger vortex velocity, indicating that the new mixer has a better mixing effect than existing mixers.
