Abstract:
1. An improvement in a process fluid treating apparatus which comprises a process fluid supply assembly, which includes an inlet section fluidically connected to a source of process fluid, an outlet section fluidically connected to the inlet section, and a longitudinal axis which extends between the inlet section of the process fluid supply assembly and the outlet section of the process fluid supply assembly; a Coanda airfoil assembly fluidically connected to said process fluid supply assembly and which includes a flow section, the flow section of said Coanda airfoil assembly being convex in shape to define a curved passageway through which process fluid flows, said Coanda airfoil assembly being fluidically connected to a source of motive fluid, a primary fluid outlet port defined in the flow section of said Coanda airfoil assembly and fluidically connected to the source of motive fluid so that motive fluid is injected into the passageway adjacent to said Coanda airfoil assembly forms a Coanda layer of motive fluid flowing adjacent to Coanda airfoil walls, the Coanda layer having shear forces and pressure gradients associated therewith; the outlet section of said process fluid supply assembly being located and oriented with respect to the Coanda layer to direct process fluid toward and into contact with the Coanda layer of primary fluid in a direction and manner so that the shear forces and pressure gradients associated with the Coanda layer are applied to the process fluid flowing in contact with the Coanda layer so that the shear forces and pressure gradients of the Coanda layer of motive fluid act on the process fluid to pump the process fluid from the process fluid supply assembly inlet section to the process fluid supply assembly outlet section and to turn the process fluid into small components, the improvement comprising: a body element mounted on said process fluid assembly to be in line with the longitudinal axis of the process fluid supply assembly and to be contacted by process fluid flowing through the process fluid supply assembly and including a shaped exit section, the exit section of the body element having a conical shape with fluid ports defined there through, the body being mounted on the process fluid supply assembly to define a fluid passage fluidically connected to the holes in the exit section of the body element, the fluid passage being fluidically connected to the inlet section of the process fluid supply assembly so process fluid flows through the fluid passage to the holes in the body element, the holes in the body element being fluidically connected to the Coanda layer so process fluid flowing out of the holes in the body element contacts the Coanda layer of primary fluid to be acted thereon by the forces and gradients of the Coanda layer of primary fluid.
