Centrifugal gas separator

Claim 2

A centrifugal gas separator comprising: drum means driven at a high rotational speed and adapted to receive a mixed gas to be separated; a housing for enclosing said drum means; means for rotatably supporting said drum within said one of said disc members which is secured to said hollow shaft; and, an inner cylindrical member mounted inside said cylindrical wall of said drum to form a passage between said cylindrical member and said cylindrical wall, said passage communicating with said conduit.

Claim 3

A centrifugal gas separator according to claim 1, wherein: said supply means has at least one opening communicating with said hollow shaft, said opening being axially disposed at an intermediate portion of said drum near the inner periphery of said cylindrical wall.

Claim 4

A centrifugal gas separator according to claim 1, wherein said supply means comprises: an axial passage extending from said hollow shaft along an axis of said drum and communicating therewith; and, at least one passage extending radially from a free end of said axial passage and communicating therewith and having an opening near the inner periphery of said cylindrical wall of said drum.

Claim 5

A centrifugal gas separator according to claim 3, wherein: the length of said axial passage is approximately one half that of said drum.

Claim 6

A centrifugal gas separator according to claim 1, wherein said exhaust means comprises: a plurality of perforations in each said disc member at an intermediate portion thereof; and, separating means for preventing a gas exhausted from said perforations in one of said disc members from mixing with another gas exhausted from said perforations in said other of said disC members.

Claim 7

A centrifugal gas separator comprising: an enclosed housing; a drum adapted to receive a mixed gas to be separated and having a cylindrical wall with disc members positioned at either end thereof, said drum driven at a high rotational speed; a pair of shafts mounted to said disc members along an axis of said drum; bearing means for rotatably supporting said shafts within said housing; exhaust means for exhausting separated gases; one of said shafts being hollow for passing said mixed gas to be separated into said drum, supply means for feeding said mixed gas flowing through said hollow shaft into said drum, near the periphery of said cylindrical wall, wherein said supply means comprises at least one conduit provided in housing; means for feeding said mixed gas to be separated into said drum means at at least one position which is at an intermediate portion thereof and is a radial distance from the axis of said drum means; and, exhaust means for exhausting separated gases, said exhaust means located nearer said axis than said feeding means, or creating a radially inward gas flow whereby said mixed gas attains a higher rotational speed than said drum means.

Claim 8

A centrifugal gas separator comprising: an enclosed housing; a drum adapted to receive a mixed gas to be separated and having a cylindrical wall with disc members positioned at either end thereof, said drum driven at a high rotational speed; a pair of shafts mounted to said disc members along an axis of said drum; bearing means for rotatably supporting said shafts within said housing; exhaust means for exhausting separated gases; one of said shafts being hollow for passing said mixed gas to be separated into said drum, supply means for feeding said mixed gas flowing through said hollow shaft into said drum, near the periphery of said cylindrical wall, wherein said supply means comprises at least one conduit provided in housing; means for feeding said mixed gas to be separated into said drum means at at least one position which is at an intermediate portion thereof and is a radial distance from the axis of said drum means; and, exhaust means for exhausting separated gases, said exhaust means located nearer said axis than said feeding means, or creating a radially inward gas flow whereby said mixed gas attains a higher rotational speed than said drum means.

Claim 9

A centrifugal gas separator according to claim 6, wherein said supply means comprises: at least one conduit provided in one of said disc members which is secured to said hollow shaft; and, an inner cylindrical member mounted inside said cylindrical wall of said drum to form a passage between said cylindrical member and said cylindrical wall, said passage communicating with said conduit.

Claim 10

A centrifugal gas separator according to claim 6, wherein: the axial length of said inner cylindrical member is approximately one half that of said drum.
