Abstract

Pour conformer des séparateurs classiques, dans lesquels des granulés (4) sont séparés de l'air porteur (3), également comme dépoussiéreur, on introduit non seulement un gaz ionisé (34) dans le récipient de granulés (9) pour neutraliser la charge électrique des particules de poussières (11) chargées électriquement, comme d'habitude jusqu'à présent, mais on introduit en plus un élément de capture (8) en matériau électriquement conducteur ou on le prévoit sous la forme d'une partie de la paroi du récipient de granulés (9), tandis que le reste de la paroi du récipient de granulés (9) doit autant que possible être en un matériau antistatique et également électriquement non conducteur. Avantageusement, le coulisseau inférieur (27) de fermeture du récipient de granulés est utilisé comme élément de capture qui est pour cette raison de préférence en métal et doit en outre être mis à la terre de sorte les particules de poussière pourvue d'une charge statique se fixent sur lui et sont transportées mécaniquement de façon simple en direction de la sortie d'air également prévue dans le coulisseau de blocage ou sont arrachées dans cette direction par l'air d'aspiration qui s'écoule à cet endroit. En outre, les particules de poussière (11) en suspension libre dans l'espace sont aspirées par une autre sortie d'air (20) prévue dans la zone supérieure du récipient de granulés (9).
