Prediction of Performance of a Hydrocyclone with Filtering Cylinder
Hydrocyclones are centrifugal devices widely used in chemical industries and they are used to the solid or liquid particles separation of a fluid according to the density and size distribution of the dispersed phase. In order to maximize the separation in these devices, this work had as objective to study the influence of the filtration during the process of separation in hydrocyclones. Thus, experimental data were used to predict the behavior of a hydrocyclone having a porous cylinder in the same operating conditions of a conventional hydrocyclone (impermeable cylinder). The experimental studies showed that the filtration interferes directly in the performance of the separator, so the filtering hydrocyclone required a higher pumping power. Moreover, the experimental data also indicated that the presence of the porous cylinder in the hydrocyclone was able to increase the number of dragged particles in the underflow, increasing therefore the efficiency of separation.
