Nozzle for dispersing viscous fluids
Abstract
Abstract A low-pressure nozzle for atomizing and dispersing a viscous fluid comprising a housing having a chamber and a diverging-wall mixing section. The chamber has inlets for the introduction of a dispersing fluid and an area of reduced cross section communicating with the mixing section. A conduit for the viscous fluid extends through the chamber to the diverging mixing section forming at the reduced cross section of the chamber a discharge outlet for the dispersing fluid. A spiral groove member is positioned in the conduit with one end of this member extending into the diverging mixing section with the grooves terminating in the mixing section by a reduction of depth of the grooves for deflecting outwardly fluid flowing in said grooves. A deflection plate is positioned in the mixing section to form an annulus between the edge of the deflection plate and the walls of the mixing section.
