Abstract
Dispositif permettant le décolmatage à contre-courant de filtres de forme plate (poches) en utilisant un système d'induction circulaire. B. Il comprend un injecteur circulaire travaillant dans un col d'induction également circulaire. Une pièce de transformation permet de transmettre l'impulsion sur une poche plate. C. L'installation peut être utilisée dans tous les domaines de filtration des gaz.
