Hydrocyclones are centrifugal devices used to perform the separation of a discrete phase (solid or liquid) from a continuous one. Depending on the process goal, particle classification, or thickening, it is possible to enhance the performance of these devices by optimizing their geometric relationships. In this study, innovative geometric relationships for a hydrocyclone were proposed to maximize the separation efficiency and provide low energy consumption. A database composed of 60 hydrocyclones with different geometric dimensions designed over 17 years of research at our laboratory was used to perform this study. Regression equations were adjusted to these previous experimental data, and a differential evolution algorithm was used in the optimization study. The optimized geometry of the hydrocyclone obtained in this work, named MOEH (maximum overall efficiency hydrocyclone), was built, and its performance was compared with the best equipment of the database through numerical simulation and experiments. The results indicated that for fine particles (D63.2 = 10.80 μm), the MOEH showed better performance than all devices already analyzed by our research group, with an overall efficiency of approximately 9% higher and a 33% reduction of energy consumption when compared with the best hydrocyclone of the database.

高效低能耗的优化水力旋流器设计
水力旋流器是离心设备，用于从连续相中分离出离散相（固相或液相）。根据工艺目标，颗粒分类或增稠，可以通过优化它们的几何关系来增强这些设备的性能。在这项研究中，提出了一种新颖的水力旋流器几何关系，以最大程度地提高分离效率并降低能耗。在我们的实验室中，经过17年的研究，设计了一个由60个不同几何尺寸的水力旋流器组成的数据库，用于进行这项研究。将回归方程调整为这些先前的实验数据，并在优化研究中使用了差分进化算法。通过这项工作获得的水力旋流器的最佳几何形状，建造了名为MOEH（最大总效率水力旋流器）的设备，并通过数值模拟和实验将其性能与数据库的最佳设备进行了比较。结果表明，对于细颗粒（D 63.2 = 10.80μm），MOEH的性能优于我们研究小组已经分析过的所有设备，与数据库中最好的水力旋流器相比，MOEH的整体效率高出约9％，能耗降低了33％。
