Improved flat fan spray nozzle

摘要

An improved spray head (16) for a nozzle (10) for atomizing a liquid (1) with a gas (g) has an open inner end (55) to receive the gas and liquid, a cylindrical medial portion (57) defining a mixing chamber (50) for creating a liquid-gas mixture, and an outer end wall (58) that has a plurality of orifices (19) arranged in a spaced circular orientation about the longitudinal axis (a) of the mixing chamber (50). Each orifice (1) defines a flow axis which is directed toward a linear target (17) located a predetermined distance (f) from the spray head (16) for atomizing and directing a respective portion of the liquid-gas mixture onto the linear target (17) in an approximately planar, flat fan spray pattern. A liquid atomizer (18, 100) is coupled in fluid communication between an inlet conduit (12) for the liquid and the mixing chamber (50) for atomizing the liquid discharged into the mixing chamber and creating the liquid-gas mixture. <IMAGE>
