  • Device for mounting filter bags in a filtering chamber
    Patent number: 5271752
    Abstract: A device for mounting vertical bag-shaped filter elements (15) in a filtering chamber in a filtering installation for cleaning contaminated gases which are conducted into the filtering chamber to be filtered by the bag-shaped filter elements and conducted, via the bag openings, to a chamber for clean gas which is located above and separate from the filtering chamber and from which the gases are discharged from the filtering installation, comprises a horizontal, lower tubular element (1) and a horizontal, upper tubular element (4) which extends along the lower tubular element (1) to which it is connected. The lower tubular element (1) forms a clean-gas chamber and has a series of first through holes (10) in its lower tube-wall portion (2b). The bag-shaped filter elements (15) can be mounted on the lower tubular element (1) with the bag openings opposite to the first holes (10).
