A swirl mixing device particularly suited for the thorough and complete mixing of a plurality of fluid reagents is disclosed. The swirl mixing device is generally composed of a cylindrically shaped container having a closed bottom and an open upper exhaust. A plurality of swirl injection levels are provided along the length of the container. Each of said swirl injection levels includes an injector set having a plurality of symmetrically spaced injectors distributed around the inner surface of the chamber wall in a plane perpendicular to the chambers's longitudinal axis. Each of said injectors in a given injector set has an injector axis directed at a given tangent circle with common radial and azimuthal directional components whereby the injected reagent enters the chamber with swirl. The injector set of each of the separate swirl injection levels has either positive or negative azimuthal components thereby injecting the respective reagents into the chamber with either positive or negative swirl such that the cumulative swirl of all reagents is small. The injector set for each of the swirl injection levels communicates with an annular chamber of a corresponding feed manifold whereby the reagent is received by and distributed around the annular chamber for injection into the mixing chamber through the injectors.
A mixing device comprising:
A swirl mixing device for mixing two reagents comprising a cylindrically shaped container having a bottom and an exhaust and two swirl injection levels spaced along the container wall, each having respective sets of injectors;
A swirl mixing device for mixing a plurality of reagents comprising a cylindrically shaped container having a bottom and an exhaust, and a plurality of injection levels, each injection level including an injector set having a respective plurality of symmetrically distributed injectors, each of said injection levels positioned at predetermined locations along the container, each of said injection levels having means for injecting the respective reagent into the container with respective preselected angular momentum injection rates such that the total angular momentum injection rate summed over all injected reagents is smaller than the angular momentum injection rate of any given injected reagent.
A mixing device comprising a container having a longitudinal axis, a bottom, an exhaust, and a first and second injection level formed in said container wall and positioned at respective predetermined locations along the axis in respective planes perpendicular to such axis, said first injection level having means for symmetrically injecting a reagent into the container at a predetermined first tangent circle such that the first reagent will enter the container with swirl having a given angular momentum;
