Abstract
An inertial-electrostatic wet precipitator for removing particulate contaminants from a gaseous stream passing through a collector tube having a discharge electrode assembly coaxially disposed therein to establish an electrostatic field between the assembly and a liquid film on the inner surface of the tube which acts to ionize the particles in the gas. Liquid for flushing the particles is fed through a pipe spiralled about the precipitator tube, the pipe terminating in a nozzle ejecting the liquid tangentially into the inlet section of the tube to impart cyclonic motion thereto. As a result, liquid is caused to flow against the inner surface of the tube in a helical path to produce the liquid film which flows toward the outlet section of the tube and is discharged into a sump. The gaseous stream to be purified is also introduced tangentially in the same sense and direction into the inlet section of the tube to impart a cyclonic motion thereto causing the gas to flow in a helical path impinging on the liquid film and imposing a pneumatic pressure thereon serving to maintain the liquid film against the inner surface even when the tube is angled with respect to the vertical.
