Liquid-solid Separation Hydrocyclones
Liquid-solid Separation Hydro-cyclonesPresented by SAAD AHMEDIn chemistry and chemical engineering, a separation process, or simply a separation, is any mass transfer process that contain a mixture of substances into two or more distinct product mixtures, at least one of which is enriched in one or more of the mixture's constituents. In some cases, a separation may fully divide the mixture into its pure constituents.Separation
figuresCyclones are huge revolving storms caused by winds blowing around a central area of low atmospheric pressure. In the northern hemisphere, cyclones are called hurricanes or typhoons and their winds blow in an anti-clockwise circle. In the southern hemisphere, these tropical storms are known as cyclones, whose winds blow in a clockwise circle.
figureA hydro-cyclone (often referred to in the shortened form cyclone) is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance.Hydro-cycloneWhen the ratio comes out greater between centripetal force on solid particles and fluid resistance. Then following two ways for separation are required:Separation by density(for dense particles).Separation by size(for coarse particles).For Coarse and Dense particlesWhen the ratio comes out low between centripetal force on solid particles and fluid resistance. Then particles must b low in density(light in weight) and very fine enough.For Light and Fine particlesA hydro-cyclone will normally have a cylindrical section at the top where liquid is being fed tangentially, and a conical base. The angle, and hence length of the conical section, plays a role in determining operating characteristics.Operating Characteristics
