Abstract
A device for filtering hot, dust-laden gases with filter tubes (2) accommodated in a closed housing (1) that contains both a dirty-gas section and a clean-gas section and consisting of hollow structures (9) that have at least one exit that communicates with the clean-gas section and are otherwise closed, characterized in that the edge (11) around the exit from each tube constitutes a base and rests subject to the weight of the tube against a counterpart in the clean-gas section such that the weight of the tube and the difference between the pressure of the gas in the dirty-gas section and that of the gas in the clean-gas section act parallel.
