Abstract

Procédé et dispositif de captage de polluants, grâce auxquels on réalise, à l'aide de premiers moyens d'aspiration, un ou plusieurs écoulements, dits écoulements primaires, d'air pollué de la zone d'émission vers lesdits moyens d'aspiration en vue d'assurer son épuration. On crée, à l'aide de seconds moyens d'aspiration, un ou plusieurs écoulements, dits écoulements secondaires, de l'air propre ou peu pollué d'au moins une zone adjacente à la zone d'émission, vers lesdits seconds moyens d'aspiration, ces écoulements secondaires étant réalisés au voisinage du ou des écoulements primaires, afin de limiter le volume de l'espace où l'air pollué est capté directement par les premiers moyens d'aspiration dans la zone d'émission. Principales applications : postes de travail dégageant de la poussière.
