摘要:
针对现有固-液分离器颗粒捕捉能力弱、结构优化不足、分离效率低的现状，设计了两种新型溢流管结构的水力旋流器。采用计算流体力学（CFD）技术和实验等方法，研究了不同溢流管结构对旋流器流场、空气柱形成、压力分布、能量损失、速度场以及分离精度的影响。结果表明：渐缩型（b型）和渐扩型（c型）溢流管有效抑制了循环流和短路流，减少了能量损失，并显著提高了分离精度。尤其是c型旋流器，其溢流管底部的收缩结构抑制了短路流，显著提高了低密度颗粒的分离效率，避免了“溢流跑粗”现象。与传统旋流器（a型）相比，新型旋流器在提高回收率和分离效率方面表现出更好的性能，在处理细颗粒时更为明显。试验进一步证明了新型溢流管设计在提高固-液分离效率方面的优势。
Abstract:
To address the limitations of current solid-liquid separators, including poor particle capture capability, suboptimal structural design, and low separation efficiency, this study proposed two novel overflow tube configurations for hydrocyclones.?Computational Fluid Dynamics (CFD) simulations and experimental methods were employed to systematically investigate the effects of these designs on flow field characteristics, air column formation, pressure distribution, energy loss, velocity profiles, and separation precision. Results demonstrated that both the converging (Type b) and diverging (Type c) overflow tubes effectively suppress recirculating and short-circuit flows, reduce energy dissipation, and significantly enhance separation accuracy. Notably, the Type c hydrocyclone features a converging structure at the overflow tube base, which mitigates short-circuit flow, markedly improving the separation efficiency of low-density particles, and preventing the "coarse particle overflow" phenomenon. Compared with conventional hydrocyclones (Type a), the novel designs exhibited superior performance in recovery rate and separation efficiency, particularly for fine particle processing. Experimental validation confirmed the advantages of the optimized overflow tube geometries in advancing solid-liquid separation efficiency, offering valuable insights for industrial separation applications.
