Abstract

La présente invention concerne un dispositif (1) de filtration de gaz pour un dispositif de fabrication additive, le dispositif (1) de filtration comprenant une colonne (3) à plateaux (31) adaptée pour la mise en contact d’un gaz (A) à filtrer avec un fluide (B) de filtration, la colonne (3) comprenant : - une première région d’extrémité (32) comprenant une entrée (33) du fluide propre (B1) en phase liquide et une sortie (34) de gaz filtré (A2), - une deuxième région d’extrémité (36) comprenant une entrée (37) de gaz (A1) chargé de particules en suspension et une sortie (38) du fluide (B2) chargé desdites particules en suspension, - une région intermédiaire (39) comprenant des moyens de mise en contact du fluide (B) en phase liquide et du gaz (A), le dispositif (1) comprenant en outre un dispositif de recyclage (53) du fluide (B2) chargé de particules en suspension pour capter les particules en suspension dans le fluide de filtration de sorte à le régénérer en fluide (B1) propre. Figure pour l’abrégé : Fig. 1The present invention relates to a gas filtration device (1) for an additive manufacturing device, the filtration device (1) comprising a column (3) with plates (31) suitable for bringing a gas (A ) to be filtered with a filtration fluid (B), the column (3) comprising: - a first end region (32) comprising an inlet (33) for clean fluid (B1) in the liquid phase and an outlet (34) of filtered gas (A2), - a second end region (36) comprising an inlet (37) for gas (A1) loaded with particles in suspension and an outlet (38) for fluid (B2) loaded with said particles in suspension, - an intermediate region (39) comprising means for bringing the fluid (B) in the liquid phase into contact with the gas (A), the device (1) further comprising a device (53) for recycling the fluid (B2) charged suspended particles to capture the suspended particles in the filtration fluid so as to regenerate it into clean fluid (B1).
