Abstract (en)

[origin: WO0000291A1] An electrostatic wet precipitator for removing particulate contaminants from a gaseous stream passing through a collector tube (3) having a discharge electrode assembly (16) coaxially disposed therein and a moving liquid film on the inner surface of the tube which acts to ionize the particles in the gas. The gaseous stream mixed with water is introduced tangentially into the tube and causing the liquid to flow against the inner surface of the tube to produce the liquid film. The ionised particles are caused to migrate toward the downwardly-flowing liquid film formed on the inner surface of the collector tube by the combined action of centrifugal and electrostatic force.
