Abstract
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.
