Abstract

Procédé de traitement d'un gaz chargé de particules gazéifiables ou combustibles consistant à faire passer l'entièreté du gaz à traiter à travers un corps poreux (1) conducteur de l'électricité et de porosité telle qu'il retient les particules, à suivre la perte de charge provoquée par le corps poreux, à interrompre automatiquement, pour une perte de charge déterminée à travers ce dernier, l'amenée de gaz, à mettre automatiquement sous tension le corps poreux pour l'amener à une température déterminée assurant la gazéification ou la combustion des particules qu'il retient, à débarrasser le corps poreux des résidus des particules par un courant gazeux et à rétablir le passage du gaz à traiter à travers le corps poreux et dispositif pour la mise en oeuvre de ce procédé.Process for treating a gas loaded with gasifiable or combustible particles consisting in passing all of the gas to be treated through a porous body (1) conductive of electricity and of porosity such that it retains the particles, to be followed the pressure drop caused by the porous body, to be automatically interrupted, for a determined pressure drop through the latter, the supply of gas, to automatically energize the porous body to bring it to a determined temperature ensuring gasification or the combustion of the particles which it retains, to rid the porous body of the residues of the particles by a gas stream and to restore the passage of the gas to be treated through the porous body and device for the implementation of this process.
