Abstract

Filtre à éléments multiples. A l'intérieur d'un cadre approprié 2 l'on dispose de façon jointive des tubes 1 fermés aux deux bouts, faits en papier-filtre, puis on immerge le bas de l'ensemble dans une résine durcissable. Après durcissement l'on découpe dans la partie durcie 6 une tranche d'épaisseur juste suffisante pour dégager l'extrémité inférieure des tubes qui peuvent ainsi recevoir le milieu à filtrer. On peut raidir les tubes en les remplissant de mousse de polyuréthane perméable; on peut les rendre moins cassants en le pré-imprégant sur une petite hauteur à l'aide de latex. Filtration des gaz.
