ABSTRACT:
A device for mixing by turbulence gaseous fluids and solid particles placed in suspension, comprising a mixing chamber into which emerge a first flow of gas introduced through an inlet located at one end of the chamber and forming a vortex which is exhausted through an outlet volute, and a second axial flow introduced through the other end and penetrating along the axis of the vortex in order to mix there with the first flow, the whole being exhausted through the outlet volute. The outlet volute is located in the central portion of the mixing chamber, the latter comprising an upper portion for the formation of the vortex between the outlet volute and the inlet for the vortex flow (A), located at the upper end of it, and a lower portion for recovery and recycling of the solid particles, in the form of a sloping surface which widens upwardly from the inlet orifice for the axial flow (B), located at the lower end of the chamber, as far as the outlet volute.
The invention is especially applicable to installations for the production of cement.
