  • Process for the production of electrically charged spray mist of conductive liquids
    Patent number: 4726521
    Abstract: The spray mist is produced by ejecting the liquid from one or more nozzles (1) in the form of jets (2) disintegrating into drops and the liquid formed from the drops is then conveyed to a spray system (4) which is electrically insulated from the nozzles (1) and a powerful electric field is applied between the nozzles (1) and the spray system (4). A spherical impact electrode or a two-material spray nozzle insulated against earth under a high voltage may be used as spray system. The main advantage is that the smooth jet nozzle (1) and hence also the container for the liquid to be sprayed are at earth potential.
