Abstract: An air assisted electrostatic liquid spray nozzle assembly having a relatively long elongated nozzle body with a spray tip and surrounding air cap disposed at a downstream end of the nozzle body. The spray nozzle assembly includes an upstream electrode for connection to a high voltage electric source, an elongated feed tube, an electrically enhancing stinger, and the spray tip which are secured and retained by the air cap in electrically conductive relation to each other such that liquid passing through liquid passages of the electrode, feed tube, stinger, and spray tip is discharged in an electrostatically charged pattern of liquid particles. The air cap is removable to permit easy removal and replacement of the spray tip, stinger, and liquid feed tube.

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

Abstract: A spray dryer for drying liquid into powder including an elongated drying chamber, a spray nozzle assembly at an upper end of the drying chamber and a filter element housing and powder collection chamber at a lower end of the drying chamber. The filter element housing comprises a plurality of cylindrical filter elements supported from a wall of an exhaust chamber that communicates with an exhaust gas outlet of the filter element housing. In one embodiment, the filter element housing includes an inner downwardly opening cylindrical shroud surrounding the filter elements which defines an outer annular powder and drying gas passageway communicating with the powder collection chamber, and the exhaust chamber is defined by a downwardly opening conical plenum having an outer conical surface for directing drying gas and powder about the shroud into the powder collection chamber. Filter elements each have a respective reverse gas pulse cleaning device.
