Separator for removing gases from water

Claim 2

A separator for removing gases from a flowing liquid stream, comprising: a housing having a central axis, a water inlet port, a water outlet port, and a gas release port; an axially-extending upper inner wall defining an outer boundary of an injection section, said inlet port opening tangentially into said inner wall; an axially-extending lower inner wall defining a collector section, said outlet port opening tangentially into said collector section, said ports being aligned in the same rotational sense relative to the central axis; a vortex tube having an axially extending cylindrical wall extending only between said injector section and said collector section, all of said walls having a respective diameter, the diameter of the vortex tube wall being the smallest of the three diameters; a separator tube having an axially extending internal cylindrical wall and an external cylindrical wall, said outer cylindrical wall having a diameter which is smaller than the diameter of the inner wall of the vortex tube so as to form an annular axially extending vortex section between said injector section and said collector section, a plurality of separator perforations extending between said walls of the separator tube, said inner wall of the separator tube forming a conduit in communication with said gas release port; and nozzle means in fluid communication with said water inlet port reducing the cross-section of an incoming stream of water and directing said stream tangentially onto said inner wall of the injection section, said nozzle means comprising structure inside said injector chambers, contiguous with the inner walls of the injection section, and including a flat plate whose plane is parallel to said central axis.

Claim 3

A separator according to claim 1 in which said housing includes an upper separator chamber with which said conduit and said gas release port communicate.

Claim 4

A separator according to claim 1 in which a disc-shaped partition extends between the inner wall of the injection section and the inner wall of the vortex tube to form between these walls, an abrupt reduction of diameter.

Claim 5

A separator according to claim 3 in which a tapered partition extends between the inner wall of the injection section and the inner wall of the vortex tube to form a gradual reduction of internal diameter.

Claim 6

A separator for removing gases from a flowing liquid stream, comprising: a housing having a central axis, a water inlet port, a water outlet port, and a gas release port; an axially-extending upper inner wall defining an outer boundary of an injection section, said inlet port opening tangentially into said inner wall; an axially-extending lower inner wall defining a collector section, said outlet port opening tangentially into said collector section, said ports being aligned in the same rotational sense relative to the central axis; a vortex tube having an axially extending cylindrical wall extending only between said injector section and said collector section, all of said walls having a respective diameter, the diameter of the vortex tube wall being the smallest; a separator tube having an axially extending internal cylindrical wall and an external cylindrical wall, said outer cylindrical wall having a diameter which is smaller than the diameter of the inner wall of the vortex tube so as to form an annular axially extending vortex section between said injector section and said collector section, a plurality of separator perforations extending between said walls of the separator tube, said inner wall of the separator tube forming a conduit in communication with said gas release port; and nozzle means in fluid communication with said water inlet port reducing the cross-section of an incoming stream of water and directing said stream tangentially onto said inner wall of the injection section, said nozzle means comprising structure outside of said injection chamber through said inlet port, and including a flat plate whose plane is parallel to said central axis, and whose intersection with the wall of the injection section is a line that is parallel to the central axis.

Claim 7

A separator for removing gases from a flowing liquid stream, comprising: a housing having a central axis, a water inlet port, a water outlet port, and a gas release port; an axially-extending upper inner wall defining an outer boundary of an injection section, said inlet port opening tangentially into said inner wall; an axially-extending lower inner wall defining a collector section, said outlet port opening tangentially into said collector section, said ports being aligned in the same rotational sense relative to the central axis; a vortex tube having an axially extending cylindrical wall extending only between said injector section and said collector section, all of said walls having a respective diameter, the diameter of the vortex tube wall being the smallest; a separator tube having an axially extending internal cylindrical wall and an external cylindrical wall, said outer cylindrical wall having a diameter which is smaller than the diameter of the inner wall of the vortex tube so as to form an annular axially extending vortex section between said injector section and said collector section, a plurality of separator perforations extending between said walls of the separator tube, said inner wall of the separator tube forming a conduit in communication with said gas release port; and nozzle means in fluid communication with said water inlet port reducing the cross-section of an incoming stream of water and directing said stream tangentially onto said inner wall of the injection section, said nozzle means comprising structure outside of said injection chamber through said inlet port, and including a flat plate whose plane is parallel to said central axis, and whose intersection with the wall of the injection section is a line that is parallel to the central axis.

Claim 8

A separator according to claim 5 in which said housing includes an upper separator chamber with which said conduit and said gas release port communicate.

Claim 9

A separator according to claim 5 in which a disc-shaped partition extends between the inner wall of the injection section and the inner wall of the vortex tube to form between these walls, an abrupt reduction of diameter.

Claim 10

A separator according to claim 7 in which a tapered partition extends between the inner wall of the injection section and the inner wall of the vortex tube to form a gradual reduction of internal diameter.
