MOUTH OF A HOOD FOR SUCKING UP FINE PARTICLES, AND LASER DEVICE FOR ABLATING A SURFACE LAYER OF A WALL COMPRISING SUCH A HOOD |
摘要 |
The invention relates to a hood for sucking up fine particles, comprising: an air intake mouth comprising a crest intended to be placed close to a wall or to emit fine particles, the crest defining an internal portion of the hood and an external portion; and a suction outlet intended to suck up the fine particles. The hood is characterized in that the mouth further includes an external lip extending towards the suction outlet and having a leading edge located on the same side as the outlet in relation to the crest, so that, when the hood is in operation, the sucked-up air undergoes no separation at the lip and that an air separation zone is located only in the internal portion of the hood. |
