A gaseous or liquid fluid to be centrifuged, for the purpose of purification or of separation of different phases, is conducted at high speed in a curved channel past a vortex chamber formed in one of the channel walls at the concave side thereof, this chamber being partly separated from the main fluid path by an overhanging sharp upstream edge and by a possibly rounded downstream edge which extend over the full width of the channel. A body of fluid whirling in this chamber develops a cylindrical core free from entrained solids, or from an accompanying heavier phase, which can be axially extracted from the chamber while the remaining fluid continues its flow through a reduced channel portion which may also be curved and provided with another vortex chamber to repeat the process. Entrained particles may be removed from the solid-enriched residual flow by way of end apertures along the periphery of the vortex chamber and/or at the convex side of the curved channel.
An apparatus for centrifugally treating a fluid, comprising conduit means forming a curved channel of substantially rectangular cross-section connected to a source of fluid to be treated for traversal by said fluid at high speed, said conduit means being provided at a concave side of said channel with at least one transverse recess extending across the full width of said channel, said recess being partly separated from said channel by a transverse upstream edge overhanging said recess and by a transverse downstream edge confronting the oncoming fluid stream, and extraction means opening into said recess adjacent a centerline thereof for axially removing a portion of a body of fluid circulating in said recess, the cross-section of said channel being larger at said upstream edge than at said downstream edge, said recess having a generally part-cylindrical periphery extending over an arc of at least 180.degree., said channel being fully open toward said recess over a complementary arc lying between said upstream and downstream edges, at least said upstream edge forming an acute vertex angle pointed in a direction tangent to said complementary arc.
