ABSTRACT:
An electrostatic spray apparatus wherein a charging chamber is formed as an enlargement in the conduit feed to the spray nozzle. The charging electrode is disposed axially of the conduit with a pointed end located at the exit end of the enlargement and facing upstream of a particle stream flow and opposed to a counterelectrode end located at the inlet side of said enlargement. The counterelectrode may be an obtuse end of an elongated element or may be formed as a grid extending across the conduit or as an annular element formed about a wall of the conduit. Optionally shown are a plurality of enlarged charging chambers, as annular element forming a constricted flow path and a charging electrode second end extending beyond the spray nozzle. Means introduce an air flow into the particle stream at both the nozzle and at the charging chamber.
