A diverter device including primary and secondary straight-line duct sections (1, 6) having a tubular quadrangular cross-section, wherein the inlet (7) of the second section (6) is located in a wall (10) of the primary section (1), a quadrangular blade is pivotably mounted in the primary section (1) via one edge (28) thereof between a position in which it seals the inlet (7) of the second section (6), i.e. an open position enabling communication with a primary air flow circuit, and a position in which the blade (27a) seals off the primary air flow circuit and diverts the incoming gas flow into the secondary section (6), as well as a connecting rod assembly (39) controlling the blade (27). The blade comprises a machined quadrangular annular bearing surface (35) engageable with a machined seat (6a) at the upstream end of the secondary section (6), and the blade (27) is pivotably mounted with limited radial clearance relative to the transverse pivot axis (XX). The device is particularly useful in facilities for processing flue gases from electrolytic cells for aluminium production. |
