水力旋流器

旋流器用于分离去除污水中较重的粗颗粒泥砂等物质的设备,有时也用于泥浆脱水,分压力式和重力式两种,水靠压力或重力由构筑物(或金属管)上部沿切线进入,在离心力作用下,粗重颗粒物质被抛向器壁并旋转向下和形成的浓液一起排出,较小的颗粒物质旋转到一定程度后虽二次上旋涡流排出。

Hydro-cyclone is mainly used in mineral processing as a classifier, and has proved extremely efficient at fine separation sizes. It is used increasingly in closed circuit operations but has found many other uses, such as desliming, deritting and thickening. It has also found wide acceptance recently for the washing of fine coal. Compare with mechanical classifier, it has the advantage of simple structure,a larger production capacity per unit volume, small occupation space, high efficient classification efficiency (up to 80% -90%), fine grading granularity, low cost, less material consumption and so on。
