Abstract

L’invention concerne un procédé de collecte et de séparation de particules présentes dans un flux fluidique, ledit procédé comportant notamment les étapes suivantes : Surveillance de la concentration de particules (P) impactées contre une bande (2) de collecte, Actionnement mécanique en translation de la bande (2) par rapport à la buse (3) d'injection des particules, lorsque la concentration de particules présentes dans une zone d'observation sur la bande de collecte dépasse une valeur seuil, Régulation de ladite vitesse de commande de la bande de collecte en fonction de la concentration de particules présentes dans la zone d'observation.
