Abstract
A centrifugal separator for purifying liquids containing impurities, has a main fluid conduit forming a passage with an inlet for receiving raw liquid to be purified, and first and second outlets. A discharge conduit is in the passage and is connected to the first outlet. A stator is positioned in the fluid passage for imparting an initial swirling axial movement to the raw liquid. A rotor positioned in the fluid passage upstream of the discharge conduit and downstream of the stator, imparts a further swirling axial movement to the raw water in the fluid passage for causing solids in the raw liquid to migrate outwardly. Clean liquid enters the discharge conduit to exit the separator via the first outlet, and solids laden liquid passes the discharge conduit and exits the separator via the second outlet.
