Abstract

L'invention concerne un filtre à précouche pour liquides. Ce filtre comporte plusieurs éléments filtrants allongés et amovibles. Une extrémité de chaque élément filtrant est supportée par un tube faisant saillie vers le haut d'une plaque à tubes. Chaque élément filtrant est relié de manière amovible au tube par un mécanisme permettant à une attache élastique de se verrouiller sous des épaulements lorsque l'élément filtrant est poussé vers le bas. Cette attache élastique est dégagée par rotation de l'élément filtrant sur un quart de tour. Un joint coulissant s'oppose à toute fuite entre les éléments filtrants et leurs tubes de support. Domaine d'application : filtration de l'eau pour centrales thermiques.
