The Structure Parameters Optimization of Co-rotating Outflow Hydrocyclone Based on Response Surface Methodology

为了进一步增强水力旋流器的分离性能,采用响应面优化方法(Response Surface Methodology,RSM)对同向出流水力旋流器的结构参数进行优化,寻优范围为大锥段长度在51.3～62.7mm、小锥段长度在120.6～147.4mm、出水管长度在90～110mm内,构建了区域内结构参数对旋流器底流口含油浓度影响的数学关系模型,并获取了最佳结构参数。开展数值模拟和室内实验,对优化后旋流器的分离性能进行验证,结果显示,优化后的旋流器结构较原始结构可将分离效率提高4.45%,实验值与模拟值呈现出了较好的一致性,充分验证了优化结果的准确性。

For purpose of enhancing the separation performance of hydrocyclones,the response surface methodology( RSM) was adopted to optimize the structure parameters of co-rotating outflow hydrocyclone,including having the optimal range of the large cone length specified from 51.3 mm to 62.7 mm and that for the small cone length ranged from 120. 6 mm to 147. 4 mm together with the length of discharging tube from 90 mm to 110 mm,meanwhile,the model of mathematical relation of regional structure parameters which influencing the oil concentration at bottom port of the hydrocyclone was established to obtain the optimum structure parameter. Simulating and experiment on the separating property of optimized hydrocyclone show that,as compared to the original structure of the hydrocyclone,the separation efficiency of the hydrocyclone with optimized structure can be increased by 4. 45%. The experimental results which coinciding with the simulation results verifies the accuracy of the optimization result.
