Abstract (en)

[origin: WO0040763A1] The preliminary cleaning stage of a dust extraction installation for blast furnace gas consists of a large-size cyclone (10) which comprises a vertical pressurized tank (14). A blast furnace gas line (12) arriving from the blast furnace is connected to an axial delivery device (34, 26, 28, 50) situated at the upper end of the pressurized tank (14). The delivery device (34, 26, 28, 50) is configured such that it introduces the blast furnace gas into the pressurized tank (14) in an axial direction. A swirl device (58) with guide vanes (66) is positioned below the axial delivery device (34, 26, 28, 50) and causes the blast furnace gas which is axially introduced into the pressurized tank (14) to swirl about the axis (30) of said pressurized tank (14).
