Abstract

La présente invention concerne une structure utilisant de la glace sèche pour le nettoyage en ligne d'un conduit d'air, comprenant un mécanisme de rampement, un mécanisme de buse, un boîtier de commande électrique (80) et un réservoir de stockage de glace sèche (90). Le réservoir de stockage de glace sèche (90) est relié au mécanisme de buse par l'intermédiaire d'un tuyau de distribution de glace sèche (91). Le boîtier de commande électrique (80) est utilisé pour commander le mouvement vers l'avant et vers l'arrière du mécanisme de rampement, et démarrer et arrêter le mécanisme de buse. Le mécanisme de rampement est utilisé pour transporter le mécanisme de buse et pour ramper dans le conduit d'air, de telle sorte que le conduit d'air est nettoyé par le mécanisme de buse. La structure utilisant de la glace sèche pour le nettoyage en ligne d'un conduit d'air se déplace dans le conduit d'air au moyen du mécanisme de rampement, et tout en rampant, pulvérise de la glace sèche sur la paroi interne du conduit d'air au moyen du mécanisme de buse. La glace sèche rend un contact fort avec la fumée et le goudron sur la paroi interne du conduit d'air sous pression normale ; et par conséquent, sublime de façon à provoquer une congélation et une expansion rapides, de telle sorte que la fumée et le goudron gèlent instantanément jusqu'à ce que la fumée et le goudron deviennent cassants, se brisent après la mise en barre, et sont ensuite soufflés par l'intermédiaire de l'air comprimé. L'invention facilite le décapage rapide de la fumée et du goudron de la paroi interne du conduit d'air, et évite les inconvénients et les déchets résultant du remplacement régulier des conduits d'air dans une usine de tabac.
