Abstract
An electrostatic precipitator is disclosed comprising a series of parallel collector electrode plates of similarly corrugated form, with the continuously curved and successive crests and valleys of the corrugations of each plate positioned in opposition to the similar crests and valleys of the adjacent plates so as to form gas-flow channels that successively converge and diverge, forming alternate narrow and wide regions along the direction of flow between each pair of plates. Of one common electrical polarity, these collector electrode plates cooperate with an array of discharge filament electrodes of opposite common polarity located between each pair of plates, with one such filament electrode centered in and extending longitudinally of each of the wide regions defined between the opposing valleys of the adjacent plates. Of critical importance to achieving the objectives of the invention, the mean spacing between plates is required to be substantially in the range from half the corrugation wave length to the corrugation wave length, and the peak-to-peak corrugation magnitude or height to be substantially in the range between ten and twenty percent of the corrugation wave length.
