1,108,318. Electrostatic precipitators. JOY MANUFACTURING CO. 14 Sept., 1965 [2 Nov., 1964], No. 39115/65. Heading B2J. An electrostatic precipitator comprises a charging electrode associated with an isolating resistance 20, the charging electrode having a predetermined amount of emitting and non-emitting surfaces 34, 26 providing sufficient capacitance in conjunction with a collecting electrode to provide sufficient capacitor current in conjunction with the spark current flow between electrodes so that the total current flow will induce a large enough voltage reduction along the spark current path to produce short duration voltage breakdowns under corona producing conditions. The arrangement ensures that when a breakdown occurs between a pair of electrodes, other electrodes in the precipitator are not affected. The discharge electrodes may be formed by tubes 34 swaged on to wires 26 and tensioned by weights 30 held 'against lateral movement by supports 32; alternatively, the electrodes may be made from barded or spaced-apart wires, flat or perforated plates &c. |
