<p>A stationary elongated vessel of substantially circular cross section having side walls and end closures is provided with a plurality of rod-like projections rigidly secured to and extending radially inwardly from the side walls at predetermined locations. A rotatably supported shaft concentrically positioned within the vessel is provided with a plurality of finger-like appendages rigidly secured thereto and extending radially outwardly from predetermined locations on the sides of the shaft. Support means maintain the concentric position of the shaft and restrict axial movement of the shaft so that the finger-like appendages intermesh with the rod-like projections in non-contacting relationship during rotation of the shaft. Inlet and outlet means are provided to introduce into and withdraw from the vessel liquids and aerosol streams. Rotation of the shaft at appropriate speeds provides effective contact between the liquid medium and the aerosol stream in the vessel.</p> |
