水力旋流器

旋流器用于分離去除污水中較重的粗顆粒泥砂等物質(zhì)的設(shè)備,有時(shí)也用于泥漿脫水,分壓力式和重力式兩種,水靠壓力或重力由構(gòu)筑物(或金屬管)上部沿切線(xiàn)進(jìn)入,在離心力作用下,粗重顆粒物質(zhì)被拋向器壁并旋轉(zhuǎn)向下和形成的濃液一起排出,較小的顆粒物質(zhì)旋轉(zhuǎn)到一定程度后雖二次上旋渦流排出。

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。
