Abstract

La présente invention concerne un appareil de filtration de métal qui, tout en étant dépourvu d'une structure complexe, permet de nettoyer de manière aisée et uniforme de multiples tubes en céramique. Une paire de panneaux latéraux (10, 11) sont disposés dans un récipient unitaire (2). Les multiples tubes allongés en céramique (13) sont fixés entre la paire de panneaux latéraux (10, 11). Le fond du récipient unitaire (2) situé sous les tubes en céramique (13) est fixé à une plaque d'injection de gaz (15) dotée d'une multitude d'ouvertures d'injection de gaz (16). Le fait d'injecter de l'argon par les ouvertures d'injection de gaz (16) de la plaque d'injection de gaz (15) permet de retirer les inclusions qui ont adhéré à la couche superficielle des tubes en céramique (13) sur le fond du récipient unitaire (2).
