Abstract (en)

[origin: EP0753706A1] The fume extraction system generates a continuous air curtain (F) along a truncated surface surrounding the extraction zone. The air is rotated and diverges as it descends along the surface. The induced fumes rise along a vortex column (F') located in the middle of the zone. The system comprise an upper dome (1) whose top (10) is located on the column axis (XX'). A lower dome (2), with the same axis, has its top displaced along the axis relative to the upper dome and has an opening (20) centred on the axis. A ventilation system (4) is placed on the axis between the tops of the upper and lower domes. The ventilation system comprises turbines for generating radial air in the air guide (3), delimited by the domes, and axial air induction in the zone through the opening. The upper and lower domes are directed downwards and widened so that the air speed vector leaving the guide has a vertical component and two horizontal components. There is a fume filtering system (5,6).
