Abstract

De fines particules d'un absorbant de type Ca, sont pulvérisées dans des gaz d'échappement, et les particules d'absorbant assimilant les substances acides toxiques des gaz sont récupérées par un collecteur de poussières avec d'autres particules des gaz d'échappement. Les particules recueillies sont réparties par un classificateur en un groupe de grosses particules contenant essentiellement de la suie et en un groupe de fines particules contenant principalement des particules d'absorbant de dimension inférieure à une valeur prédéterminée; seul le dernier groupe étant envoyé dans un réacteur à hydration.Fine particles of a Ca-type absorbent are sprayed into exhaust gases, and particles of absorbent assimilating toxic acid substances from the gases are recovered by a dust collector with other particles of the exhaust gases . The particles collected are divided by a classifier into a group of large particles containing essentially soot and into a group of fine particles containing mainly absorbent particles of dimension smaller than a predetermined value; only the last group being sent to a hydration reactor.
