    摘要:

    针对农业滴灌中黄河水泥沙含量高的问题,将碟式分离机与FXJ-150-I型水力旋流器串联用于黄河水泥沙分离。采用正交试验、极差和方差分析研究了串联分离设备参数对溢流量和溢流颗粒D50的影响。试验结果表明:影响溢流量的参数主次排列为旋流入口压力、旋流器底流口直径和转鼓转速, 而影响溢流D50的参数主次排列为旋流入口压力、转鼓转速和底流口直径。考虑试验因素对溢流量和溢流中粒径D50影响程度的大小以及它们在分离中所起作用的大小,优化了串联分离设备参数:旋流入口压力为0.06 MPa、底流口直径为12 mm、转鼓转速为3500 r/min。

    Abstract:

    To solve the problem of high content of bedload in Yellow River’s water for agricultural drip irrigation, the dish separator and FXJ-150-I hydrocyclone was connected in series to seperat silt from Yellow River’s water. The influences of the series connection seperation equipment on the overflow flux and sediments half-content diameter D50 were studied by orthogonal test, range analysis and variance analysis. The results show that the important order of the parameters influencing the overflow flux is as follows:inlet pressure, underflow port diameter and drum rotation speed. As for the D50, the order is inlet pressure, drum rotation speed and underflow port diameter. Considering the influence extent of tested factors on the overflow flux and sediments half-content diameter D50 and the separation efficiency, the parameters of the equipment are optimized as follows: inlet pressure 0.06 MPa, underflow port diameter12 mm, drum rotation speed 3500 r/min.
