Abstract (en)

[origin: DE19911850A1] The invention relates to a method for limiting, detecting and sucking off harmful substances by means of extractor devices. The intake flow field of the extractor devices is supported by blowing out. A frontal shear flow that limits the vapour and a transport flow that concentrates the harmful substances at the intake locations are generated by a plurality of blown out streams. In an alternative embodiment, an eddy flow that concentrates the harmful substances, preferably in a spiral manner, is created by a plurality of blown-out streams and by superimposing an annular blowing flow with the intake flow field.
