Abstract
Small highly charged droplets are produced without concurrent production of corona by conducting a liquid to a nozzle having a tip from which droplets of the liquid can exit, and forming a substantially uniform electric field over the surface of the liquid on the tip, the field being large enough to pull off droplets from the tip but not so large as to create corona discharge. Selected gas, solid particulates and liquid mists from gaseous effluents such as are produced by smelters, coal or oil-burning steam generators, chemical refineries and the like are removed by means of a unique electrostatic collector using the highly charged droplets. These droplets are caused to drift, by means of an electric field, through the gaseous effluent to a collecting electrode absorbing selected gases and aerosol particles and carrying them to a collecting electrode.
