Abstract

L'INVENTION CONCERNE UN PROCEDE ET UN APPAREIL POUR DEBARRASSER UN GAZ D'UNE MATIERE SOLIDE FINEMENT DIVISEE. POUR ELIMINER UNE MATIERE SOLIDE FINEMENT DIVISEE ENTRAINEE PAR UN GAZ, ON FAIT PASSER LE GAZ DE DEPART TRANSVERSALEMENT A UN LIT MOBILE DE MATIERE PRESENTANT UNE FAIBLE CONDUCTIVITE ELECTRIQUE ET ON DISPOSE DANS LE LIT MOBILE UN ELEMENT CONDUCTEUR DE L'ELECTRICITE AUQUEL EST APPLIQUEE UNE TENSION COMPRISE ENTRE ENVIRON 2000 ET 50000VOLTS, LEDIT ELEMENT ETANT DIMENSIONNE ET CONFIGURE DE FACON QU'IL NE GENE PAS LE DEPLACEMENT DU LIT OU LA CIRCULATION DU GAZ DE DEPART A TRAVERS LUI. APPLICATION A L'EPURATION D'UN GAZ CHAUD.THE INVENTION CONCERNS A METHOD AND AN APPARATUS FOR CLEARING A GAS FROM A FINALLY DIVIDED SOLID MATERIAL. TO ELIMINATE A FINALLY DIVIDED SOLID MATERIAL DRIVEN BY A GAS, THE STARTING GAS IS TRANSVERSALLY TRANSFERRED TO A MOBILE BED OF MATERIAL PRESENT A LOW ELECTRIC CONDUCTIVITY AND A CONDUCTIVE ELEMENT OF ELECTRICITY IS APPLIED IN THE MOBILE BED. BETWEEN APPROXIMATELY 2000 AND 50,000VOLTS, THIS ELEMENT BEING SIZED AND CONFIGURED SO THAT IT DOES NOT GENERATE THE MOVEMENT OF THE BED OR THE FLOW OF THE STARTING GAS THROUGH IT. APPLICATION TO THE PURIFICATION OF HOT GAS.
