A device for additional cleaning of dustladen medium, which to some extent has already been cleaned in an electrostatic presipitator.

摘要

An arrangement for further cleansing a dustladen medium which has already been cleansed to some extent in an electrostatic precipitator (1). Part of the medium cleansed in the precipitator is arranged to be removed therefrom through a duct (10) for recirculation in the precipitator and/or for further cleansing in a separate cleaning unit intended herefor. Arranged in the outwardly sloping lower part of the outlet section, as seen in the flow direction, is one or more openable outlets, wherewith the removed part of the medium flow can be taken out through the outlet intermittently over periods of time during which high dust concentrations prevail and/or are expected to prevail.
