Particulate material including germanium-containing particulate, such as germanium dioxide (GeO2), is captured from the exhaust stream loop (L) of a glass production system (12) by an exhaust fan (16) in a filtration system employing a baghouse (18) consisting of baghouse modules (20) containing filter bags (21) of a PTFE (polytetrafluoroethylene) filter membrane supported by a PTFE fabric backing and pre-loaded with SiO2 from a SiO2 supply system (30). The captured particulate material is collected from the filtration system by an associated collection system comprising a scrubber fan (22) and scrubber system (24) before exhaust leaves the facility (10) through the exhaust stack (26). The glass produced by the production system (12) consisting of vapor deposition lathes (14) and (28) is selected such that the concentration of germanium in the particulate material collected from the filtration system is at least about 2 % by weight.

La présente invention concerne un procédé de capture de matière particulaire comprenant des particules contenant du germanium, comme du dioxyde de germanium (GeO¿2?), dans un circuit fermé de gaz d'émission (L) d'une installation de production de verre (12). Ladite capture est effectuée, à l'aide d'un ventilateur d'évacuation (16), dans un ensemble de filtres à poches (18) composé de modules (20), contenant chacun des poches (21) faites de toile de PTFE (polytétrafluoroéthylène) recouverte d'une membrane filtre en PTFE, et préchargées de SiO¿2? à partir d'une source de SiO¿2? (30). La matière particulaire capturée est récupérée dans le système de filtres à l'aide d'un système collecteur associé constitué d'un ventilateur d'extraction (22) et d'un laveur de gaz (24) à la sortie duquel les gaz quittent l'installation (10) par la cheminée (26). On choisit le type de verre à produire dans l'installation de production (12), constituée de tours de dépôts par évaporation (14 et 28), de manière à ce que la concentration en germanium dans la matière particulaire, récupérée par l'ensemble de filtration, soit au moins de 2 % en poids environ.
