摘　　要：水力旋流器分离过程难以实现低能耗高效率的操作,现提出一种锥形溢流管的开缝结构。通过研究试验与响应面模型,以旋流器分离效率与压降为目标函数,实现锥形溢流管开缝层数、开缝位置及开缝角度的优化设计分析。针对100 mm型旋流器,采用中值粒径为41.52μm的玻璃珠细粉测试,实验结果表明:在一定范围内开缝定位尺寸对旋流器分离性能影响较小;开缝角度和层数对旋流器分离性能影响显著。得出最优组合是溢流管开缝层数为3层、开缝定位尺寸为5.3 mm、开缝角度为58°的旋流器。较之常规型水力旋流器,经多次实验得出入口流量为920 mL/s,旋流器分离效率增幅率为0.26%,达到最高,压降降低率为24.88%,可见节能效果显著。In order to solve the difficulty of achieving low energy consumption and high efficiency operation in the separation process of hydrocyclones,a conical overflow pipe slit structure is proposed,and the design and analysis of the number of slit layers,seam position and seam angle of the conical overflow pipe are optimized by studying the test and response surface model,taking the separation efficiency and pressure drop of the hydrocyclone as the objective function.For the 100 mm hydrocyclone,the fine powder of glass beads with a median particle size of 41.52μm was used,and the test results showed that the slit positioning size within a certain range had little effect on the separation performance of the hydrocyclone,and the slit angle and number of layers had a significant effect on the separation performance of the hydrocyclone.The optimal parameter combination of improved hydrocyclone is 3 slit-layers,5.3 mm slit positioning size and 58°slit angle of the overflow pipe.Compared with the conventional hydrocyclone,after the inlet flow rate is optimized at 920 mL/s,the separation efficiency of the hydrocyclone reaches the highest,with an increase rate of 0.26%and a pressure drop reduction rate of 24.88%,which shows that the energy-saving effect is remarkable.
