Abstract: In an aerosol separator for removing dust particle and droplet aerosols from a flow of contaminated gases, comprising an essentially vertical channel section through which the contaminated gas (exhaust gas) is conducted upwardly, and into which an easily vaporizable liquid is sprayed, in finely divided droplets, a densely packed tube bundle of essentially identical straight tubes consisting of a process-suitable inert material is arranged supported on a perforated conical support structure such that moisture contained in the gas flow is deposited on the inner and outer tube surfaces and flows downwardly counter to the gas flow through the tube bundle and is collected in a gutter mounted to the inner wall of the tube bundle at the bottom end thereof for conducting the condensed liquid together with the contamination of the gas out of the aerosol separator.

Abstract: A wet electrostatic ionization stage in an electrostatic separation device for purifying a flowing aerosal including finely dispersed particles entrained in a gas. The wet electrostatic ionization stage includes a plate disposed across a cross section of a flow channel and connected to a ground potential or reference counterpotential. The plate includes substantially identical openings through which the gas flows. The wet electrostatic ionization stage also includes a high-voltage grid disposed across the cross section of the flow channel either upstream or downstream from the plate and electrically isolated from a wall of the flow channel. The high voltage grid is coupled to a high voltage potential via a bushing disposed in the wall of the flow channel. For each opening in the plate, a rod-shaped high-voltage electrode coupled at one end to the high-voltage grid has a free end projecting centrically into the one opening.
