An electrostatic precipitator has a dust-collecting assembly wherein a pair of dust-collecting electrodes, usually at positive polarity, flank an array of discharge electrodes (at negative polarity) having corona-discharge parts or edges. According to the invention, the discharge electrodes have, opposite the corona-generating points or edges, broad surfaces of a large radius of curvature to serve as collecting surfaces for dust particles charged by reverse ionization. Advantageously, along the path of the gas through the assembly, the corona-discharge and collector surfaces of the discharge electrodes alternate with one another. |
