COLLECTOR STAGE OF AN ELECTROSTATIC SEPARATOR FOR CLEANING FLUE GAS CREATED IN COMBUSTION PROCESSES, AND METHOD FOR OPERATING THE SAME

摘要

The collector stage of an electrostatic separator for cleaning flue gas created in combustion processes comprises a collector stage, having at least one collector pipe in which an at least single-coil brush is rotatably supported. The brush comprises a central rod or pipe placed coaxially to the collector pipe, on the outer lateral region of said rod or pipe brush wires being placed at a radial distance to the coil axis, which contact at the free end thereof the interior wall of the collector pipe in a grazing manner such that particles are brushed away upon the rotation of the brush toward the interior wall of the collector pipe. The collector pipe and the brush are connected to a common electric reference potential.
