ABSTRACT:
In an improvement of the apparatus and method disclosed in U.S. Pat. No. 7,354,029 B1, a Process Fluid Treating Apparatus includes an ejector assembly fluidically connected to a process fluid supply assembly. A Coanda airfoil is located in the ejector assembly. Primary fluid is injected into the ejector duct and forms a Coanda layer, flowing adjacent to the walls of a Coanda Airfoil. A process fluid, or part of it, flows toward the ejector assembly through the Process Fluid Supply Assembly, which forces the process fluid to flow through a plurality of fluid ports to separate that process fluid into a plurality of separate streams and turns those separate streams of process fluid through its perforated tip towards the Coanda layer whereby the contact between the process fluid and the Coanda layer is controlled. Shear and other forces and pressure gradients associated with the Coanda layer serve to transport the process fluid from the source and to operate on the process fluid to atomize the process fluid and/or to de-agglomerize solid particles entrained in the process fluid. Alternatively, a mechanical pump could be used for process fluid delivery to the Coanda layer.
