Abstract
Solid particulates are removed from a solid particulate-laden fluid stream by passing the solid particulate laden fluid stream into a potential flow centrifugal separator which splits the potential solid particulate-laden fluid stream into a clean fluid stream and a concentrated solid particulate-laden fluid stream, passing the concentrated solid particulate-laden fluid stream into a solids collector which extracts solid particulates from the concentrated solid particulate-laden fluid stream leaving a fluid stream having a reduced solid particulate content, and conducting the fluid stream having a reduced solid particulate content back into the potential flow centrifugal separator for further processing.
Claims15
Apparatus constructed and arranged for removing solid particulates from a solid particulate-laden fluid stream comprising:
- a. a centrifugal separator arranged for splitting the solid particulate-laden fluid stream into a clean fluid stream and a concentrated solid particulate-laden fluid stream, said centrifugal separator being cylindrically shaped and having a tangential inlet, and axial outlet and a sidewall, said solid particulate-laden fluid stream entering said centrifugal separator through said tangential inlet, said clean fluid stream exiting said centrifugal separator through said axial outlet, said sidewall being constructed to provide an outlet to enable passage through of said concentrated solid particulate-laden fluid stream, said centrifugal separator having no conical parts, no surfaces normal to the centrifugal separator axis in immediate proximity to the axial outlet and no means for producing flow U-turns within said centrifugal separator,
- b. a solids collector separate from the centrifugal separator and arranged for receiving the concentrated solid particulate-laden fluid streams from said centrifugal separator, extracting solid particulates therefrom and producing as a result thereof a fluid stream having a reduced solid particulate content, and
- c. means for mixing said fluid stream having a reduced solid particulate content back with said particulate-laden fluid stream upstream of said centrifugal separator, said means including an ejector.
