Abstract: De-dusting of gases is carried out in an apparatus containing a granular-bed filter, the pourable granular filter medium flowing downward through the bed. The apparatus comprises a vessel of rectangular cross-section with a vertical side wall (4) extending from the top to the bottom. A partition (5), arranged parallel to the side wall (4), extends from the upper end of the vessel into the interior of the vessel. The remaining three side walls of the vessel extend - at least starting from a level corresponding to the lower end of the partition (5), taperingly downward to the outlet (9). The partition (5) is supported by the two walls adjacent to the vertical wall and forms, together with these and with the talus (7) of the filter medium, which arises at the lower end of the partition, a chamber (3) into which the inlet (2) for the gas to be purified opens. At the inlet (10) for the filter medium, located at the upper end of the partition, a further talus (12) of the filter medium forms, defining a collecting chamber (16), in which the outlet (17) for the purified gas is located.

Abstract: A flange coupling for joining together ends of multi-layer apparatus sections or pipeling sections, in which corrosive and hot gases are handled, each section consisting of an inner lining of glass which is resistant to thermal shock, or of quartz, the inner lining being surrounded by an outer metal jacket, the interspace between the outer jacket and the lining being packed with a heat-insulating material which supports the inner lining. The coupling comprises refractory bricks provided between the lining of a section and the outer jacket at the end portions of said lining, said bricks surrounding without touching the entire surface of the lining at said ends portions thereof. One end of the lining terminates inwardly of the end of the corresponding refractory brick. Flange means are provided for coupling together the adjacent ends of the jackets of two adjacent sections.
