摘要:
在旋流分离过程中，油滴尺寸分布会因聚合与破裂现象而产生改变，从而对分离效率产生影响.利用Fluent软件结合群体平衡模型及多尺寸分组方法在考虑相间相互作用的情况下，对脱油Matthias Meyer水力旋流器中油滴浓度及直径分布进行了模拟.结果表明：含群体平衡模型的方法较不含群体平衡模型的方法所得到的分离效率精确度更高，与实验数据相比较误差分别为2%与6%.模型中聚合现象较破裂现象明显，使得大直径油滴含量增大且聚集在内旋流及圆柱段，而小直径油滴含量减小且聚集在圆锥段.分散相破裂效率与湍流耗散率成正比，聚合效率与油相浓度成正比的关系得到了验证.
Abstract:
In the separation process of hydrocyclone, the distribution of the size of oil droplets changes with the coalescence and breakage, and it affects the separation efficiency. Considering the interphase interaction，the Fluent software combined with population balance model and multisizemodel was adopted to simulate the concentration and size distribution of oil droplets in the deoiling Matthias Meyer’s hydrocyclone. The results show that the separation efficiency obtained by the population balance model is more accurate than that without the population balance model and the errors between the simulated data and the experimental data are 2% and 6% respectively. As coalescence is more obvious than breakage in this model, the concentration of the large oil droplets increases and the large oil droplets gather in the inner swirling flow and the cylindrical section, while the concentration of the small oil droplets decreases and the small oil droplets gather in the conic section. The relationships are verified that the efficiency of breakage is proportional to the turbulent dissipation rate and the efficiency of coalescence is proportional to the concentration of the oil phase.
