Abstract
In a reaction-driven centrifugal rotor the interior of its casing is divided into one separation chamber (11) and one outlet chamber (12). The separation chamber (11) has an inlet (8) for pressurized liquid to be treated in the centrifugal rotor, and the outlet chamber (12) has outlets (24) for treated liquid. The outlets (24) extend out through one end wall (1) of the casing from the outlet chamber to the outside of the casing. They are situated at a distance from the rotational axis (R) of the centrifugal rotor and directed in a way such that the centrifugal rotor is subjected to a reaction force in its circumferential direction, when liquid flows out therethrough. An annular partition (9) arranged coaxially with the centrifugal rotor within the casing separates the separation chamber (11) from the outlet chamber (12). However, the two chambers communicate with each other through a space at the radially inner edge of the partition (9). The invention is concerned with liquid entrainment members (25, 26), which are arranged in the outlet chamber (12) and formed in a way such that they impede liquid flow in the circumferential direction of the centrifugal rotor relative to the centr…
