摘要

实验研究了直径为 35mm的除油水力旋流器能量耗散与分流比的关系 .结果发现

当改变溢流孔径 (分别为 4、 6、 8mm)和入口流量 (分别为 30、 40、 5 0、 6 0、 70L·min-1)时

只要分流比小于 2 5 %

旋流器的能量耗散在不同入口流量下都能保持与入口流量对应的某一常数值 .当入口流量分别为 30、 40、 5 0、 6 0、 70L·min-1时

旋流器的能量耗散大约分别为 10、 30、 80、 140、 2 0 5N·m·s-1.根据旋流器的这一特征

并结合理论分析

建立了除油水力旋流器压降比数学模型 .该模型预测计算的压降比与分流比关系曲线与实验室测定的结果能很好地吻合

Abstract

The correlation between energy dissipation and split ratio in a 35mm diameter de-oiling hydrocyclone was established by experiment.under the conditions of different overflow orifice diameters

as long as the split ratio is less than 25%

energy dissipation was a constant.It only changed with inlet flow rate.When the inlet flow rate was 30

70L·min -1

the energy dissipation is about 10

140

205N·m·s -1 respectively.Based on this characteristics of hydrocyclone and theoretical analysis

a prediction model of de-oiling hydrocyclone was proposed.The prediction of pressure drop ratio was identical with the test data.
