Abstract

Ce procédé consiste en la dispersion individuelle de fines particules indépendantes d'un absorbant de type Ca dans un gaz porteur jusqu'à forte concentration par un dispositif diviseur-disperseur auquel le gaz porteur et l'absorbant sont alimentés, les particules de l'absorbant se caractérisant par un diamètre maximum de 10 microns, en l'introduction de l'aérosol à haute concentration ainsi obtenu dans les gaz d'échappement pour l'obtention d'un mélange uniforme et, ensuite, en l'introduction des gaz d'échappement dans un collecteur de poussières.This process consists in the individual dispersion of fine particles independent of an absorbent of type Ca in a carrier gas until high concentration by a divider-disperser device to which the carrier gas and the absorbent are supplied, the particles of the absorbent characterized by a maximum diameter of 10 microns, in the introduction of the high concentration aerosol thus obtained in the exhaust gases to obtain a uniform mixture and, then, in the introduction of the exhaust in a dust collector.
