Title
(EN) A FILTER ASSEMBLY HAVING A FILTER ELEMENT AND A SEALING DEVICE
(FR) ENSEMBLE FILTRE COMPRENANT UN ELEMENT FILTRANT ET UN DISPOSITIF D'ETANCHEITE
Abstract
(EN)
The present invention provides a filter assembly in which a ceramic tube filter (9) may be preassembled with first (2) and second (13) sealing elements prior to installation. The preassembled filter assembly has an advantage in that the seal between the ceramic filter and the metal sealing device may be tested in the manufacturing stage prior to installation in the field. Additionally, a tube sheet including filter assemblies according to the present invention may locate the filter assemblies closer together, thus reducing the pitch between the filter elements.
(FR)
La présente invention concerne un ensemble filtre qui est constitué d'un filtre tubulaire en céramique (9) qui peut être préassemblé avec un premier (2) et un second (13) élément d'étanchéité avant installation. L'ensemble filtre préassemblé présente l'avantage résidant dans le fait que le joint entre le filtre céramique et le dispositif d'étanchéité métallique peut être soumis à un essai pendant l'étape de fabrication, avant installation dans le champ d'utilisation. En outre, sur une plaque tubulaire servant à porter des ensembles filtres selon la présente invention, il est possible de placer lesdits ensembles filtres plus près les uns des autres, ce qui réduit la distance séparant les éléments filtrants les uns des autres.
