Title (EN) MOUTH OF A HOOD FOR SUCKING UP FINE PARTICLES, AND LASER DEVICE FOR ABLATING A SURFACE LAYER OF A WALL COMPRISING SUCH A HOOD
(FR) EMBOUCHURE D'AVALOIR D'ASPIRATION DE PARTICULES FINES ET DISPOSITIF D'ABLATION LASER D'UNE COUCHE SUPERFICIELLE D'UNE PAROI COMPRENANT UN TEL AVALOIR
Abstract:
(EN) The invention relates to a hood for sucking up fine particles, comprising: an air intake mouth (30) comprising a crest (3b) intended to be placed close to a wall (2) or to emit fine particles, the crest (3b) defining an internal portion (31) of the hood and an external portion (32); and a suction outlet (5) intended to suck up the fine particles. The hood is characterized in that the mouth (3b) further includes an external lip (40) extending towards the suction outlet (5) and having a leading edge (41) located on the same side as the outlet (5) in relation to the crest (3b), so that, when the hood is in operation, the sucked-up air (8) undergoes no separation at the lip (40) and that an air separation zone is located only in the internal portion (31) of the hood.
(FR) L'invention concerne un avaloir d'aspiration de particules fines, comprenant : une embouchure (30) d'entrée d'air comportant une crête (3b) destinée à être disposée à proximité d'une paroi (2) pouvant émettre des particules fines, la crête (3b) définissant une partie interne (31) de l'avaloir et une partie externe (32); et une sortie d'aspiration (5) destinée à aspirer les particules fines. L'avaloir est caractérisé en ce que l'embouchure (3b) comporte en outre une lèvre (40) externe s'étendant vers la sortie d'aspiration (5) et comportant un bord (41) d'attaque situé du même côté que la sortie (5) par rapport à la crête (3b), de sorte que, lorsque l'avaloir est en fonctionnement, l'air (8) aspiré ne subit aucun décollement au niveau de la lèvre (40) et qu'une zone de décollement de l'air ne se situe qu'en partie interne (31) de l'avaloir.
