水力旋流分离器在油水分离领域的研究进展

水力旋流器利用密度差实现两相分离,具有结构简单、分离效率高等优点,因此在原油预脱水处理等油水分离领域得到广泛应用。 鉴于此,通过分析和收集水力旋流器相关文献,对油水分离领域水力旋流分离器的研究现状进行了阐述和总结,包括水力旋流分离器的发展历程、基本结构、内部流场和工作原理等相关方面;同时,对油水分离领域不同类型的水力旋流分离器进行了对比分析,发现在水力旋流器的结构参数优化以及内部液体流动规律等方面,单一结构的参数优化或单一、静态的系统分析不能系统全面地反映实际复杂工况。 因此,将计算机仿真模拟和相关先进检测技术相结合,用于旋流器的参数优化、内部液体流动规律分析以及构建预测模型等方面,对于旋流器的结构设计优化、分离效率提升等方面意义重大;另外,目前的研究多着重于旋流器的结构和流体特性等方面,对于旋流器内部的磨损、疲劳损伤等方面的研究较为缺乏;最后,对水力旋流分离器在油水分离方面研究的不足和发展方向进行了分析和展望。

Research Review of Hydrocyclone for Oil-water Separation

The hydrocyclone uses density difference to realize two-phase separation which has the advantages of simple structure and high separation efficiency so it is widely used in oil-water separation fields such as the pre-dehydration of crude oil. In view of this the research status of hydrocyclone in the field of oil-water separation was expounded and summarized by analyzing and collecting relevant literature on hydrocyclone including the development history basic structure internal flow field and working principle of hydrocyclone. Meanwhile different types of hydrocyclones in the field of oil-water separation were compared and analyzed. It is found that in the aspects of structural parameter optimization and internal liquid flow law of hydrocyclones single structural parameter optimization or single and static system analysis cannot systematically and comprehensively reflect the actual complex working conditions. Therefore the combination of computer simulation and related advanced detection technology is of great significance for the optimization of cyclone parameters the analysis of internal liquid flow law and the construction of a prediction model and is also of great significance for the optimization of cyclone structure design and the improvement of separation efficiency. In addition the current research mostly focuses on the structure and fluid characteristics of the cyclone while the research on the internal wear and fatigue damage of the cyclone is lacking. Finally the research deficiency and development direction of hydrocyclone in oil-water separation were analyzed and prospected.
