摘要
利用计算流体动力学(Computational Fluid Dynamics,CFD)软件Fluent,采用群体平衡模型(Population Balance Model,PBM),以常规双锥型液-液旋流分离器结构为基础,研究聚结器Ⅰ~Ⅵ(不同结构形式)对聚结性能的影响。分析了不同截面上油相体积分布、油相粒径分布及油相迹线分布等,对不同粒径聚结性能的影响,获取了不同结构形式聚结器出口粒径分布和变化规律。结果表明:油相在聚结器Ⅴ经聚结后出口粒径最大可以达到290μm,且含有粒径270、290μm的油相数量最多。同时在截面3,聚结器Ⅴ粒径最大,且整体看聚结器Ⅴ粒径大多集中在200μm,表明聚结器Ⅴ聚结效果最好。
Through using Fluent software of the CFD, adopting the population balance model(PBM)and basing on the structure of conventional double-cone liquid-liquid cyclone separator, the effects of the coalescer Ⅰ-Ⅵ(six structural forms) on the coalescence performance were studied, including the effect of oil volume distribution, oil particle size distribution and oil trace distribution on the coalescence properties of different particle sizes to get the particle size distribution at the outlets of different structural forms and the change rule. The results show that, the maximum size of the oil phase at the exit of the coalescer Ⅴ can be up to 290μm, and the oil phase with the particle size of 270μm and 290μm is the most abundant. In section 3, the particle size of coalescer Ⅴ is the largest and the particle size of coalescer Ⅴ is mostly concentrated at 200μm in the whole, which indicates that the coalescence effect of coalescer Ⅴ is the best.
