ABSTRACT:
Spraying apparatus comprising a shroud in the form of a tube flared at one end and made of electrical insulating material, said shroud adapted for connection to an air supply such that in operation a high velocity air stream issues from the flared end of the shroud, at least one air shear nozzle mounted inside the shroud adjacent the flared end, a tube adapted for connection to a liquid spray source for supplying the nozzle such that in operation the liquid is atomized by the high velocity air flow and the expansion of compressed air from the supply passing over the nozzle, means for maintaining the liquid in the nozzle at ground electrical potential, a high voltage metal electrode positioned inside the flared end of the shroud in spaced relation to the nozzle, and means for supplying high voltage to the electrode such that in operation the electrode carries a high voltage positive or negative potential effective to charge by induction liquid particles or droplets issuing from the said nozzle.
