Abstract: An electrostatic sprayer (10, 70) operable at high flow rates and low pressures particularly suitable for spray drying. The sprayer (10, 70) includes an elongated body (12) having a downstream spray nozzle assembly (14, 71) through which electrically charged liquid is directed via a central feed tube (18) within the nozzle body (12) and atomizing air is supplied via an annular passage (25) about the liquid feed tube (18). In one embodiment, the nozzle assembly is an external mix cluster head spray nozzle assembly (14) having a plurality of circumferentially spaced metallic spray tips (40). In another embodiment, the spray nozzle is an internal mix nozzle assembly *71) having a spray tip (71) with an internal mixing chamber (72a) for atomizing liquid prior to discharge.

Abstract: A spray device (10) for discharging a liquid as a mist is provided. The spray device (10) includes a main body (12) including a reservoir (26) for storing the liquid to be discharged and an atomizing assembly (30) in fluid communication with the reservoir (26) and including an ultrasonic atomizing head (36) configured to shear the liquid into droplets using sound waves. A spray nozzle (14) includes a nozzle body (78) with an inlet (80) in communication with the atomizing assembly (30) and a discharge orifice (82). The nozzle body (78) defines a first passage (84) that communicates with the spray nozzle inlet (80) and the discharge orifice (82). The nozzle body (78) includes a charging electrode (90) arranged in a second passage (94) that connects to the first passage (84).
