Device for separating gaseous mixtures

Claim 1

A centrifugal apparatus for the separation of a gaseous mixture into a light component and a heavy component, comprising: a plurality of disks connected to a common hollow shaft which is in communication with the centrifugal separator's gaseous mixture inlet and rotatable at high speed about a common axis, each of said disks having a central supply region at said axis, a radial passage extending outwardly from said supply region and including a first nozzle orifice having a constriction, a chamber radially outwardly of said first nozzle orifice and communicating therewith while being of larger cross section than said nozzle orifice, another radial passage in flow communication with said chamber opposite said nozzle orifice and including a second nozzle orifice having a constriction whereby a heavy fraction from a gas mixture is led through said second nozzle orifice, a heavy-fraction delivery passage communicating with said second chamber substantially centrally thereof, and respective light-fraction delivery passages communicating with each of the chambers of the respective disks to opposite sides of said nozzle orifices and said heavy-fraction delivery passage; first conduit means connected to the heavy-fraction delivery passage of one of said disks; and second conduit means connected to the light-fraction delivery passages of said one of said disks, one of said first and second conduit means being positioned and arranged so as to discharge the respective fraction into the supply region of another of said disks.
