ABSTRACT:
A bladeless mixing device for use in a mixing system to mix streams of the same or different composition, for example, liquid/liquid, gas/gas, solid/solid, or any combination thereof. In the mixer device streams are tangentially directed into an inlet mixing chamber comprising a convergent conical cavity wherein a converging vortex is created, which is passed through an orifice into an outlet mixing chamber comprising a divergent conical cavity wherein a diverging vortex is developed, which is extracted from the outlet cavity tangentially for subsequent passage through further stages of the mixing system. The streams are combined, separated and recombined several times during the course of their passage through the mixing system which comprises a plurality of stages, until the desired mixing is obtained. The orifice size may be varied, depending upon the extent of mixing and velocity required for thorough mixing of the streams.
