Abstract

A tubular collector for precipitating electrically loaded aerosols from a gas stream stands vertically in a gas stream duct. The stream flows upwards in the section. The tubular collector includes at least one group of pipe bundle which extends at the most over the internal width of the duct and including at least one dimensionally stable pipe bundle whose lower side or side that faces the flow rests on a grating or perforated metal sheet connected to an electric reference potential. At least the top side or side away from the stream of a group of pipe bundles is uniformly sprayed with rinsing liquid. The pipes of a group of pipe bundles are held apart by spacers so that the stream flows over their outer and inner sides. The pipes of a group of pipe bundles are identical and have different adjustment heights. The pipes have such a length that at least when a turbulent flow enters one pipe, a laminar gas stream is formed downstream.
