Abstract
An improved electrode for use in an electrostatic precipitator is disclosed. The electrode comprises a generally rod-shaped conductive central portion, to which are attached a plurality of conductive disc-shaped elements. Each disc-shaped element has a number of sharp points spaced around its circumference and a plurality of openings near its center. The central portion of the central portion passes through the centers of each of the plurality of disc-shaped elements such that the disc-shaped elements are located parallel to one another along the central portion, and may be equally spaced along the central portion. The disc-shaped elements are conical or convex in shape, and oriented with their rims raised above their centers so that any water that collects on them runs out through the openings and down the central portion of the electrode. This greatly reduces or eliminates arcing between the electrode and a collector in the electrostatic precipitator.
