Abstract
An electro-inertial precipitator unit for removing particulate contaminants from a gaseous stream passing through a collector tube having a discharge electrode coaxially disposed therein to establish an electrostatic field between the electrode and a downwardly-flowing liquid film on the inner surface of the tube. The gaseous stream is introduced tangentially into an upper inlet section of the tube to impart a swirling motion thereto, the liquid being supplied to an annular inlet slot just below the gas inlet section. Because of the centrifugal force generated by the swirling motion, the particles in the gaseous stream are urged to migrate toward the liquid film, this migration being further promoted by the electrostatic force acting on the particles which are charged with ions in the field. To avoid the formation of dust streaks on the inner surface of the tube, which tend to occur with relatively low liquid flow rates, the gaseous stream flowing therethrough is pulsed.
