Abstract
A decanter centrifuge includes one or more nozzles through which a slurry may be discharged from a feed chamber into a separation zone within a centrifuge bowl. A scroll conveyor may be coaxially aligned in the separation zone within the centrifuge bowl around the circumference of the feed chamber. In the separation zone, the slurry can be separated into at least a light phase and a heavy phase by centrifugal acceleration generated by rotation of the centrifuge bowl, the feed chamber, and/or the scroll conveyor. Each separated phase can discharge from the centrifuge bowl via respective discharge ports. Each nozzle may include a rectangular aperture and differentiated profiles of its leading edge and trailing edge. In some embodiments, the leading edge of the aperture comprises a rounded profile, while the trailing edge comprises an abrupt edge or a less-rounded edge.
