Abstract:
A electrostatic spray nozzle comprising:a nozzle body made of an electrically conductive material and having a front end, a back end, and a middle section, the nozzle body including a hollow passage extending from the front end to the back end and the middle section having a channel extending generally perpendicular to the hollow passage for allowing entry of a gas into the hollow passage, the hollow passage including a mixing region adjacent the front end of the nozzle body;a liquid tube inserted through the hollow passage extending form the back end of the nozzle body and terminating in the mixing region to deliver a liquid to mix with the gas in the mixing region to form an atomized liquid; andan electrode made of an electrically conductive material and having an orifice, the electrode being connectable to the front end of the nozzle body so that, in operation, the atomized liquid flows through the orifice thereby charging the atomized liquid responsive to an electrical potential applied to the nozzle body.
