ABSTRACT:
A purging electrostatic gun for uniformly and essentially completely electrostatically charging the outer surfaces of a flow of sorbent material particles passed therethrough under pressure that are then injected into a polluted gas stream for contacting to electrostatically attract and react to pollutant particles and pollutant gases in that gas stream that are then removed in a conventional pollution control filtration device. The purging electrostatic gun includes a housing wherein a charging electrode is maintained that is electrically coupled to receive a high voltage and is axially centered in a cylindrical barrel charging section wherethrough a laminar flow of sorbent material is directed. The charging electrode has a forward portion that extends beyond a barrel charging section forward end and is immediately opposite to a surface of a grounding ring or collar. The grounding ring or collar is maintained in the housing and is connected to earth ground. A purging air flow is directed into the housing to pass across the barrel charging section outer surface and the grounding ring or collar surface to prohibit sorbent particles from collecting on the grounding ring or collar as could interfere with generation of a corona discharge that extends from the charging electrode end portion radially wherethrough the sorbent material particles travel and are electrostatically charged.
