Abstract

Procédé de fabrication d'un filtre destiné à épurer un courant gazeux par rétention d'une substance qui y est présente sous la forme de particules atomiques ou moleculaires. Le procédé selon l'invention consiste à choisir la longueur 1 de la matière filtrante et le diamètre libre effectif (deff ) ainsi que la nature même de la matière filtrante de manière à ce que le coefficient de perméabilité delta (1, t) conserve pendant toute la durée de service prévue pour le filtre une valeur prédéterminée delta (1,t) = e**-De, le symbole De désignant le nombre de Von der Decken. Application notamment à la fabrication de filtres destinés à l'équipement des réacteurs nucléaires refroidis par gaz.A method of manufacturing a filter intended to purify a gas stream by retaining a substance present therein in the form of atomic or molecular particles. The method according to the invention consists in choosing the length 1 of the filtering material and the effective free diameter (deff) as well as the nature of the filtering material so that the permeability coefficient delta (1, t) remains the entire service life provided for the filter a predetermined value delta (1, t) = e ** - De, the symbol De designating the Von der Decken number. Application in particular to the manufacture of filters intended for the equipment of gas-cooled nuclear reactors.
