Abstract

A dust-collecting electrostatic precipitator in which the collecting plates are constituted from interlocked thin sheet-metal strips with loosely interengaging edges and are suspended at the top from a common carrier, in which stabilization is increased against vibration by providing the lateral edges of the plates with short retaining members in a single horizontal zone or in a plurality of such zones spaced apart vertically from one another. The retaining members are interconnected by a rigid element. The system is particularly suited for tall electrostatic precipitators having a height of, say, 15 meters in which high gas velocities would otherwise cause extensive vibration of the electrode strips.
