摘要 为了探究结构参数对聚并-旋流耦合油水分离器性能的影响,基于水力聚结机理和旋流分离理论,通过计算流体动力学分析方法,以聚并-旋流耦合油水分离器结构参数为研究对象,油水分离效率为指标,开展多场耦合油水分离装置的结构参数优化设计。针对不同螺旋流道长度和聚结管段长下的聚并-旋流耦合油水分离器结构模型,进行数值模拟研究验证,探究不同结构参数下模型的分离性能。结果表明,在聚并器螺旋流道长度L2=100 mm、聚结管段长L3=350 mm时分离效率达到最高。选取不同入口流量和分流比对聚并-旋流耦合油水分离器最优结构的不同工况下的分离性能进行分析,当入口流量Q=8m3/h、分流比F=40%时,油水分离效率达到最高值93.62%。 For purpose of exploring structural parameters’influence on the performance of coalescence-cyclone coupled oil-water separator,having the hydraulic coalescence mechanism and cyclone separation theory based,the computational fluid dynamics analysis method adopted,the structural parameters of coalescence-cyclone coupled oil-water separator taken as the research object and the oil-water separation efficiency as the index to optimally design structural parameters of the multi-field coupled oil-water separator was implemented.According to the structural model of coalescence-cyclone coupled oil-water separator with different spiral channel length and coalescence pipe length,numerical simulation was carried out to explore its separation performance under different structural parameters.The results show that,the separation efficiency is the highest when the coalescer spiral channel length L2=100 mm and the coalescence pipe length L3=350 mm.Having different inlet flow rate and split ratio selected to analyze separation performance of the polymer-cyclone coupled oil-water separator under different working conditions and boasting of the optimal structure indicates that,when the inlet flow rate Q is 8 m3/h and the shunt ratio F is 40%,the oil-water separation efficiency reaches the highest value of 93.62%.
