Title (EN) PLEATED MULTILAYER FILTER FOR PULSED OPERATION
(FR) FILTRE MULTICOUCHE PLISSÉ POUR FONCTIONNEMENT PULSÉ
Abstract:
(EN) The invention relates to a pulse filter (100; 110) having two stage filters (101, 102; 113, 114), each having filtering properties different from each other. The first stage filter (101; 113), through which the fluid flow to be cleaned passes first, is arranged to filter coarser materials and the second stage filter (102; 114) is arranged to filter finer substance from the fluid flow. The first (101; 113) and second stage filter (102; 114) are formed as separate pleated structures, which are optionally a distance forming an air gap (103; 115) away from each other.
(FR) L'invention concerne un filtre à impulsions (100; 110) comprenant deux filtres à étage (101, 102; 113, 114) présentant chacun des propriétés de filtrage différentes les unes des autres. Le premier filtre à étage (101; 113) à travers lequel l'écoulement de fluide a nettoyé passe en premier, est agencé pour filtrer des matières plus grossières et le second filtre à étage (102; 114) est agencé pour filtrer une substance plus fine à partir du flux de fluide. Le premier filtre à étage (101; 113) et le second filtre à étage (102; 114) sont formés sous la forme de structures plissées séparées, qui sont éventuellement une distance formant un espace d'air (103; 115) à l'opposé l'une de l'autre.
