Abstract

On utilise un filtre de séparation de suspension dans les industries chimiques, alimentaires et agricoles. Dans ledit filtre, un flux continu d'une suspension est orienté vers le bas dans un espace (13) situé entre des éléments filtrants (4), lesquels sont nettoyés simultanément au moyen d'un flux de gaz passant à travers des orifices (15) de tube (14) sous la forme de bulles sur la surface de chacun des éléments filtrants (4), d'un côté de l'écoulement de la suspension, et dans le sens opposé à celui de cet écoulement. Les éléments filtrants (4) se composent de réservoirs creux (8) reliés à un manchon (5) d'extraction de filtrat. Les tubes (14) sont situés dans la partie inférieure des éléments filtrants (4) le long et à proximité de leurs côtés latéraux, de sorte que les bulles sortant des orifices se déplacent le long de la surface des éléments filtrants (4) et nettoyent ces derniers.
