An electrostatic atomizing device for ejecting a mist of charged minute particles includes metal ion elution means for eluting sterilizing metal ions into a liquid to be electrostatically atomized. The metal ions are taken up by the charged minute particles, and are ejected into an environment space together with the charged minute particles, thereby eliciting a sterilizing effect. The elution amount of the metal ions is regulated by varying the voltage applied between two kinds of metal bodies.

An electrostatic paint atomizer connected to a discharge station at high voltage is supplied, via an isolating conveying line, with individual divided-off quantities of paint enclosed between two pigs from a loading station at the other end of the conveying line. The paint is conveyed by a transport device supplying a thrust medium (compressed air or insulating liquid) to discharge the paint in the discharge station. A reverse transport device operating with compressed air transports the pigs back to the loading station. The length (L) of the conveying line between the loading and the discharge stations and the length (l) of a divided-off quantity of paint, are dimensioned to provide a sufficiently long isolating path (L-l) to avoid a voltage flashover. A continuous supply of paint is achieved with two parallel conveying lines, through which quantities of paint are metered with an offset from each other.
