<p>A Multi-concentric wet electrostatic precipitator of large operating capacity, wherein concentric annular gas passages having the same radial dimensions are defined by a series of vertically-disposed, concentrically-arranged tubes of progressively increasing diameter, inner and outer surfaces of adjacent tubes which form the walls of the passages having downwardly-flowing, uniform liquid films produced thereon. A discharge-electrode structure is disposed in each annular passage, a high voltage being applied between the electrode structures in the several passages and their associated liquid films which act as collectors, thereby causing contaminants in a gaseous stream conveyed upwardly through the passages to be ionized and to migrate toward the films to be carried downwardly thereby for disposal, gas emerging from the upper end of the passage being free of contaminants.</p> |
