Abstract

Dispositif de filtration d'air ambiant passif comprenant une chambre en forme de boîte, une entrée de vent, un ensemble de plaques perforées, des pièces d'accélérateur réglables, des plaques de collecteur réglables, et une sortie de vent. Les plaques perforées sont inclinées et supportées vers le haut de la chambre et inclinées vers l'intérieur le long de la direction du vent entrant provenant l'entrée de vent. Les pièces d'accélérateur sont positionnées sur chaque plaque perforée et sont positionnées adjacentes à une perforation formée sur la plaque perforé.. Les plaques de collecteur sont positionnées verticalement le long de la surface des plaques perforées. Des particules provenant du vent entrant soufflant à travers l'entrée de vent entrent en contact avec chaque plaque perforée et sont accélérées le long de chaque pièce d'accélérateur afin d'entrer en contact et d'être collectées sur chaque plaque collectrice. Les particules collectées sont transférées par l'intermédiaire des perforations à une section inférieure de la chambre par l'intermédiaire de la gravité et l'air exempt de particules est extrait de la sortie de vent.
