Patent ID: 7682427

Claim:
A tubular collector for precipitating out electrically charged aerosols from a gas stream, comprising: a vertical section of a duct used for guiding the gas stream from a bottom of the duct to a top of the duct; at least one tube bundle group anchored in the section of the duct, the tube bundle group comprising at least one tube bundle that extends across a cross section of the duct and includes an upper end and lower end, wherein at least the lower end is positioned to face the gas stream; a grid, coupled to the at least one tube bundle group, that extends across the cross section of the duct and is further connected to an electric reference potential, wherein at least one tube of the at least one tube bundle conductively contacts the grid to discharge an absorbed electrical charge; and a spraying device mounted centrally above the tube bundle that uniformly sprays a rinsing liquid on at least the upper end of the tube bundle, wherein immediately adjacent tubes in the tube bundle are positioned parallel to one another and at a distances of 0 mm≦s≦D inside relative to each other, with D inside representing the inside diameter of the tubes, and wherein the tubes in the at least one tube bundle group have different adjustment heights.
