动态水力旋流器及其试验装置

Dynamic hydrocyclone and its test bed.

由动力源、单旋体及进 /出液口等组成的动态水力旋流器 ,作为油水混合液的处理装置 ,在电动机的带动下高速旋转 ,内部液流迫旋切向速度高 ,能够提高油水分离效率。同静态水力旋流器比较 ,动态水力旋流器切向速度的最大值在主直径方向半径的三分之一处 ,并且以最大值为界 ,形成两个涡 ,即外部为自由涡 ,内部为强制涡 ,是一种组合涡的结构。轴向速度的特点是液体在器壁附近和核心处各有一个高速的轴向速度区 ,而在二分之一半径附近却存在一个很低的轴向速度区。为了深入研究动态水力旋流器的性能和机理 ,设计了一种能够模拟现场工况的。

The working principle and advantages of dynamic hydrocyclones were introduced. Their velocity field was analyzed. Comparison between the dynamic cyclone and static cyclone shows that the former has higher separation efficiency. To make a further investigation in the performance and mechanism of the dynamic hydrocyclone, a test bed was designed. The flow chart.structural parameter,structure of the main body and the characteristics of the test bed were presented.
