Abstract

A filter arrangement for purifying waste gases from aluminum electrolytic cells, in particular from tanks of this kind provided with precooked anodes, comprising means for adding alumina to the gas stream for the chemical sorption of the gaseous fluorides and a filter for following bag from which the separated powder and alumina are recirculated to the electrolytic cells, characterized in that in front of said means for adding alumina and the bag filter an electric filter is arranged which in the selection of the filter length, the gas velocity and electric voltage thereof is adapted to give a selective separation of only heavy metal compounds, in particular iron, and of the possible carbon-containing powder.
