| 摘要 |
The present invention relates to a separator and more specifically, but not exclusively, to a centrifugal separator for the cleaning of a gaseous fluid. The centrifugal separator (2') comprises: a housing (4') defining an inner space, an aperture for permitting the flow of a fluid along a flow path between the exterior of the housing (4') and the inner space, and a shoulder (6') upstanding from the housing (4') and surrounding the aperture. The shoulder comprises a curved surface (221) extending inwardly into the aperture. The separator further comprises a nipple (22') connectable to the shoulder (6') such that an internal surface (216) of the nipple (22') combines with the curved surface (221) of the shoulder (6') to provide a curved surface to the flow path. More particularly the internal surface (216) of the nipple meets with the curved surface (221) at an edge (229) of the shoulder (6') and, at this meeting point, is oriented tangentially to the curved surface (221). |
