Abstract

Procédé de filtrage d'un courant de gaz chargé de très fines particules solides, microniques ou submicroniques. On effectue le filtrage sur des parois filtrantes en tissu, et l'on injecte dans ledit courant de gaz des particules auxiliaires nettement plus grosses, propres à constituer une pré-couche filtrante sur lesdites parois, une partie au moins des poussières recueillies dans la trémie du filtre étant recyclée. Principales applications : installations émettant des particules tres fines, par exemple installation de décriquage ou d'oxycoupage.
