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.
