Abstract
Abstract To impart a twist in an incoming flow of raw gas in a tornado flow separator, an inlet duct located within and coaxial to a vortex chamber is provided with at least one supply inlet for the raw gas extending tangentially thereto and communicating therewith. The inlet duct has a closed end which is substantially conical in shape.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
177 words
In a tornado flow separator including a cylindrical vortex chamber defined by a cylindrical chamber wall, an inlet duct for raw gas to be purified in the separator disposed within and coaxial with the chamber at one end thereof, an outlet for gas purified in the separator located at the other end of the chamber, auxiliary gas supply inlets extending tangentially to the chamber wall in the vicinity of the purified gas outlet and being inclined with respect to the chamber wall so as to supply a flow of auxiliary gas to the chamber opposite in direction to the flow of raw gas therein, and means defining an annular discharge gap coaxially surrounding the raw gas inlet duct for discharging from the chamber particles separated from the raw gas supplied thereto, a device for applying a twist to the raw gas supplied to the separator comprising at least one raw gas supply tube connected tangentially to the inlet duct for supplying raw gas thereto, the inlet duct having a closed lower end having a substantially conical shape.
Claim 2
Dependent Claim
177 words
In a tornado flow separator including a cylindrical vortex chamber defined by a cylindrical chamber wall, an inlet duct for raw gas to be purified in the separator disposed within and coaxial with the chamber at one end thereof, an outlet for gas purified in the separator located at the other end of the chamber, auxiliary gas supply inlets extending tangentially to the chamber wall in the vicinity of the purified gas outlet and being inclined with respect to the chamber wall so as to supply a flow of auxiliary gas to the chamber opposite in direction to the flow of raw gas therein, and means defining an annular discharge gap coaxially surrounding the raw gas inlet duct for discharging from the chamber particles separated from the raw gas supplied thereto, a device for applying a twist to the raw gas supplied to the separator comprising at least one raw gas supply tube connected tangentially to the inlet duct for supplying raw gas thereto, the inlet duct having a closed lower end having a substantially conical shape.
Claim 3
Dependent Claim
36 words
Device for applying a twist to raw gas supplied to a tornado flow separator according to claim 1 including a rotationally symmetrical elongated flow body located within the inlet duct and extending along the axis thereof.
Claim 4
Dependent Claim
34 words
Device for applying a twist to raw gas supplied to a tornado flow separator according to claim 2 wherein the substantially conical closed lower end of the inlet duct merges with said flow body.
Claim 5
Dependent Claim
37 words
Device for applying a twist to raw gas supplied to a tornado flow separator according to claim 1 wherein said raw gas supply tube is disposed in a plane perpendicular to the axis of the inlet duct.
Claim 6
Dependent Claim
53 words
Device for applying a twist to raw gas supplied to a tornado flow separator according to claim 1 wherein said gas supply tube is connected to the inlet duct at an angle to the axis of the inlet duct and substantially parallel to the incline of the substantially conical closed lower end thereof.
Claim 7
Dependent Claim
87 words
Device for applying a twist to raw gas supplied to a tornado flow separator according to claim 1 including at least two gas supply tubes extending parallel to and adjacent one another, one of said gas supply tubes being located radially outwardly from the other and partly surrounding the inlet duct, said one gas supply tube communicating with the interior of the inlet duct at a location offset 90* from a location at which the other gas supply tube communicates with the interior of the inlet duct.
Claim 8
Dependent Claim
36 words
Device for applying a twist to raw gas supplied to a tornado flow separator according to claim 1 including an annular diaphragm mounted on the outside of the inlet duct above said raw gas supply tube.
Claim 9
Dependent Claim
62 words
Device for applying a twist to raw gas supplied to a tornado flow separator according to claim 7 includIng nozzles for supplying additional air provided in the wall of the inlet duct above said annular diaphragm, said nozzles being disposed tangentially to the inlet duct wall and being inclined to the direction of flow of the raw gas within the inlet duct.
