Abstract
A discharge electrode is disclosed for producing ion emission in an electrostatic precipitator. The electrode includes a rigid cylindrical tubular member having a plurality of protrusions extending outwardly therefrom. The protrusions preferably have rounded free end portions and are formed either by individual rods integrally attached to the member or by one or more wires attached to the surface of the member and having folds which are selectively spaced apart to provide the desired dispersion of the ion emission. The wires may also be embedded in depressions defined in the surface of the member. The invention also pertains to an improved electrostatic precipitator incorporating the inventive discharge electrode.
