Abstract

Filtre pour épuration d'un courant gazeux par rétention d'une substance qui y est présente sous forme de particules atomiques ou moléculaires, comprenant une cavité entourée d'une enveloppe étanche aux gaz et destinée à être traversée par le courant gazeux, cette cavité contenant une matière filtrante qui assure la rétention desdites particules par interaction avec celles-ci Selon l'invention, la matière filtrante comporte des passages pour l'écoulement du courant gazeux qui épousent la forme de structures géométrique ordonnées, et la longueur l et le diamètre hydraulique deff sont dimensionnés de manière à rendre maximal le produit l/deff .St' (nombre de Stanton). Application notamment à l'équipement des réacteurs nucléaires refroidis par gaz.Filter for purifying a gas stream by retaining a substance which is present therein in the form of atomic or molecular particles, comprising a cavity surrounded by a gas-tight envelope and intended to be traversed by the gas stream, this cavity containing a filter material which ensures the retention of said particles by interaction with them According to the invention, the filter material comprises passages for the flow of the gas stream which follow the shape of ordered geometric structures, and the length l and the hydraulic diameter deff are dimensioned in such a way as to maximize the product l / deff .St '(Stanton number). Application in particular to the equipment of gas-cooled nuclear reactors.
