【摘要】 本文针对导叶式除油型水力旋流器的特点,研究了入口流量、溢流率、叶片出口角度、叶片出口面积等参数对该水力旋流器分离性能的影响规律,同时,应用APV激光测速技术对此类液-液水力旋流器内部速度场的分布特征以及上述几个参数对该水力旋流器内部流场的影响规律进行研究。首先,建立了流场测试试验台架,应用APV激光测试系统对DN50型导叶式除油型水力旋流器内部速度场(主要是切向速度和轴向速度)进行了测试分析,得出导叶式除油型水力旋流器内部速度场的分布图,并对水力旋流器内切向速度与轴向速度的分布规律、切向速度分布对称性、切向速度准自由涡参数和轴向零速包络面等问题进行了分析和研究。其次,基于DN50型导叶式除油型水力旋流器的性能试验结果,得出了入口流量、溢流率这两个操作参数的最佳工作范围;优化了叶片出口角度、叶片数这两个结构参数。由此为基础,借助于APV激光测试系统对这几个参数对水力旋流器内部切向速度和轴向速度的影响情况进行实测,从流场分布特征角度分析研究这几个参数对该液-液水力旋流器分离性能的影响,研究结果为液-液水力旋流器分离机理的研究以及操作参数、结构参数的优化提供了参考依据。更多还原

【Abstract】 Performance experiment was carried through for vane-guided type of de-oil hydrocyclone. The infection for separating performance by some parameters was introduced,including entry flux, flooding rate, the exit angle of vane and the number of vane. And the flow field of this hydrocyclone was measured by laser testing instrument. Furthermore, the study on those parameters which are important for the separation performance wasexpounded in this paper.First of all, the shelf for laser testing was built. The flow field of this hydrocyclone, which type is DN50, was measured by APV. It was mostly showed that the tests of tangent velocity and axial velocity in this kind of hydrocyclone. As the analysis of the result of the test, the velocity distributing chart and the study on parameter of subaltern free vortex and LZVV was introduced in this paper.Secondly, the prime range of those parameters was found in analysing the result of performance experiments for the type of DN50. The flow field of vane-guided type of de-oilhydrocyclone was measured in different parameters by laser testing instrument according these results. Infection for separating performance by these parameters was studied in the view of flow field. And all results above provided a base for further research on the separation mechanism and optimization for the parameters of the new hydrocyclone.更多还原
