Abstract

L'invention concerne les dispositifs d'épuration des gaz d'échappement un dispositif d'épuration dans lequel les Elle se rapporte à un dispositif d'épuration dans lequel les gaz sont déviés radialement par des trous de la tuyauterie d'entrée et viennent frapper un garnissage formé de toile métallique ou de métal déployé, dans une première chambre annulaire, avec absorption de particules de plomb; les gaz passent alors dans une chambre qui leur donne un mouvement tourbillonnaire puis pénètrent dans un conduit convergent qui est limité par un garnissage poreux, si bien que d'autres particules de plomb sont séparées par un effet centrifuge, la composante tourbillonnaire du courant gazeux étant alors supprimée avant évacuation par une tuyauterie de sortie. Application à l'épuration des gaz d'échappement des moteurs à combustion interne.
