ABSTRACT:
Air atomizing induction charging spray nozzles suited for use with conductive liquids, solutions, suspensions or emulsions. These systems feature a high level of the spray charging at low induction--electrode voltage and current. Primary benefits include consistent, reliable operation in harsh agricultural and industrial environments with a wide range of spray formulations, especially those having relatively high concentrations of abrasive and conductive materials. Internal and external surfaces are configured to minimize potential differences between electrode and ground. Such nozzles may employ external cavities, field concentrators, hoods and other structures and arrangements to affect aerodynamic flow of gases within the vicinity of the nozzles and electrostatic and electrodynamics effects such as those caused by electrical fields within the vicinity of the nozzles.
