ABSTRACT:
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.
