Bete Fog Nozzle, Inc.

A gas and liquid mixing nozzle for an abrasive type slurry is characterized by a central liquid passage and a helical vane disposed about the outlet end of the liquid passage to deflect the liquid outwardly into a generally flat spray pattern. The vane portion of the nozzle is preferably a separate insert formed of abrasion resistant material. An annular orifice is coaxially disposed about the outlet end of the liquid passage to eject an air stream into the liquid spray to mix therewith and form an aerated, high velocity spray. At the outer end of the helical vane is a deflector plug having a generally planar inner surface against which the liquid, issuing from the nozzle passage, impinges. The plug has a substantial axial length approximately the same as the axial dimension of the vane portion of the nozzle, and its outer periphery is inwardly and outwardly tapered toward the outer surface of the plug. This contour provides for a spray pattern of uniform droplet size.

Gas liquid mixing nozzle

Fluid spray for generating rectangular coverage area which includes a tubular conduit or header carrying a fluid under pressure and a pair of spaced nozzles. Each nozzle includes a bore which receives liquid from the header and conducts it toward a concavely curved end wall. Each nozzle has a circumferentially extending orifice adjacent the end wall which faces toward an identical orifice of the other nozzle so that the spray from one nozzle impinges upon the spray from the other nozzle.

Fluid spray for generating rectangular coverage

A full cone spray nozzle, particularly for liquids bearing fibrous particles and the like, having a pair of swirl imparting vanes within the bore of the nozzle. Transversely of the bore, the vanes are approximately semi-circular segments, each having a central recess to provide an opening for liquid flow in axial alignment with the outlet orifice of the nozzle. The vanes overlap circumferentially on diametrically opposite sides of the opening. In the direction of liquid flow, each semi-circular segment is generally sinusoidal, having a convex loop in one quadrant of the passage facing upstream and a concave loop also facing upstream in an adjacent quadrant of the passage. The curved loop portions of each vane are interconnected by an axially extending leg which cross at about the center of the bore and being recessed define the central opening.
