| 摘要 |
The invention relates to a cyclonic separator comprising a throat portion (4) which is arranged between a converging fluid inlet section and a diverging fluid outlet section, which is arranged to generate a swirling fluid flow in a downstream direction. The diverging fluid outlet section comprises outlets (6, 7) comprising an inner primary outlet (7) for condensables depleted fluid components and an outer secondary outlet for condensables enriched fluid components (6). The cyclonic separator comprises at least one volute diffuser (9, 9′) connected to one of the outlets (6, 7), the at least one volute diffuser (9, 9′) comprising a volute outlet duct (90, 90′) defined by a volute axis (I1), forming a spiral shape around the central axis (I). The outlet duct (90, 90′) comprising a vortex chamber 95, in use the vortex chamber 95 is provided to transform axial momentum of the swirling fluid flow with respect to the central axis (I) into tangential momentum with respect to the volute axis (I1).
