Abstract
A nozzle of converging-diverging shape for creating mist flow at supersonic velocity comprising: a throat having a characteristic diameter D*; an inlet having a characteristic diameter D1, positioned a distance L1 upstream of the nozzle throat; and an outlet having a characteristic diameter D2, positioned a distance L2 downstream of the nozzle throat, wherein the ratio of L2/(D2−D*) is larger than 4, but smaller than 250; an inertia separator based thereon, and a method for supersonic separation of one or more components of a predominantly gaseous stream.
Claims14
A nozzle of converging-diverging shape comprising:
- a throat having a characteristic diameter D*;
- an inlet having a characteristic diameter D1, positioned a distance L1 upstream of the nozzle throat;
- and
- an outlet having a characteristic diameter D2, positioned a distance L2 downstream of the nozzle throat, wherein the ratio of L2/(D2−D*) is larger than 4, but smaller than 250.
An inertia separator for supersonic separation of a component of a predominantly gaseous stream, comprising a nozzle, the nozzle comprising:
- a throat having a characteristic diameter D*;
- an inlet having a characteristic diameter D1, positioned a distance L1 upstream of the nozzle throat;
- and
- an outlet having a characteristic diameter D2, positioned a distance L2 downstream of the nozzle throat, wherein the ratio of L2/(D2−D*) is larger than 50, but smaller than 220;
- and
- a separation section downstream thereof having at least one outlet for the component that is separated and at least one outlet for the remaining gaseous stream.
A method for the supersonic separation of a component of a predominantly gaseous stream, using an inertia separator comprising a nozzle, the nozzle comprising:
- a throat having a characteristic diameter D*;
- an inlet having a characteristic diameter D1, positioned a distance L1 upstream of the nozzle throat;
- and
- an outlet having a characteristic diameter D2, positioned a distance L2 downstream of the nozzle throat, wherein the ratio of L2/(D2−D*) is larger than 50, but smaller than 220;
- and
- a separation section downstream thereof having at least one outlet for the component that is separated and at least one outlet for the remaining gaseous stream.
