为了更好地掌握液-液水力旋流器内油水流动和分离特性与结构的关系,采用计算流体力学的有限体积法(FVM),对其轻相分离过程进行了非稳态的数值计算,得到了轻相(油)在旋流器内的逐渐分离、聚积和运移的过程,分析发现,大锥段和小锥段的分离效果明显,尤其在小锥段的中心区轻相(油)聚积的浓度最高。因此,对大锥段和小锥段优化设计是提高旋流器分离效率的最重要的方面之一,可以进一步研究锥段的过渡型式,如采用高次曲线。
In order to better understand the relationship between the flow and separation characteristics of oil and water and the structure in the liquid-liquid hydrocyclone, the finite volume method (FVM) of CFD was used to calculate the unsteady state of light phase separation. The process of gradual separation, accumulation and migration of light phase (oil) in the cyclone was obtained. It was found that the separation effect of large cone and small cone was obvious, especially in the light phase ) Accumulation of the highest concentration. Therefore, optimizing the design of large and small cone sections is one of the most important aspects to improve the efficiency of hydrocyclone separation. The transition type of cone section can be further studied. For example, the high-order curve is used.
