液液旋流分离器内流动偏心现象的试验研究

旋流分离器中空气柱(旋流中心)溢流端偏心反映了旋流分离器内流动的不对称性。通过试验研究表明，旋流分离器的操作参数对溢流端旋流中心的偏移的影响并不显著，而主要决定于旋流分离器的输入结构形式，随输入结构形式不对称性的增加，流动偏心的程度也在增加。揭示了液液(除油型)旋流分离器内流动不对称性对分离效率的影响，这对进一步提高旋流分离器分离效率具有重要的指导意义。

Test research and analysis on asymmetry of flow within liquid-liquid hydrocyclones

This paper is focused on the investigation of the asymmetry of flow within hydrocyclones through the observation of eccentricity of air core at vortex finder. Results show that operating parameters have a negligible effect on the eccentricity of the flow. In fact, the eccentricity of the flow largely depends on the pattern of inlets of a hydrocyclone, and the eccentricity of the flow have effect on the separation efficiency of a deoiling hydrocyclone. It could be used as a guide for the design of hydrocyclones to reach higher separation efficiency.
