  • Apparatus and method to produce charged fog
    Patent number: 4854500
    Abstract: Electrostatically charged liquid such as water is supplied via rotating structure to impinge on a baffle. The latter deflects the charged liquid onto a rotating insulative, frusto-conical surface on which the charged liquid forms a film which flows forwardly to an annular edge. Gas such as air, sweeping past the edge, impacts the layer arriving at the edge and produces fine charged droplets of the liquid, forming a fog. This charged fog is usable for suppressing dust particles in the air.
