ABSTRACT:
A coaxial centrifugal separator device has a linear pipe fixed diameter exterior, with a coaxial pipe entrance with multiple internal helical spiraling vanes disposed and secured to the interior wall of the pipe length, the interior helical spiraling vanes providing a centrifugal motion to the fluid multi-phase input flow into the centrifugal device. The centrifugal motion imparted to the multi-phase input fluid finally separates the total input fluid into flowing concentric streams in the device, the fluid stream having the lowest density being centered along the centrifugal device pipe centerline. The highest density particulates stream is disposed along the interior wall of the centrifugal device in a generally laminar flow. Thus, in an application to a three phase fluid stream pumped into the centrifugal separator device, the coaxial centrifugal separator device produces a central axially disposed lower density stream which can be removed from the downstream output by a centrally coaxially disposed probe tube in the device, and which exits to a low density phase tank collector. The denser-than water solid phase which forms as a laminar exterior phase of the multi-phase fluid is collected in an exteriorily disposed in-line collar of the centrifugal device disposed coplanarly with the probe tube collecting the centrally disposed phase.
