Abstract

L'INVENTION CONCERNE LA NEUTRALISATION ET LE REFROIDISSEMENT DES GAZ ACIDES CHAUDS. AVANT NEUTRALISATION DU GAZ, CELUI-CI PENETRE DANS UN CYCLONE FORMANT UN COURANT SPIRALE ASCENDANT DE GAZ, SI BIEN QUE LES GROSSES PARTICULES SONT SEPAREES ET SE CONCENTRENT SUR LA PAROI DU CYCLONE SOUS L'ACTION DES FORCES CENTRIFUGES. LE COURANT ASCENDANT DE GAZ EST ALORS AU CONTACT D'UNE PULVERISATION ASCENDANTE D'UN LIQUIDE DE NEUTRALISATION. LE PRODUIT OBTENU PEUT ENSUITE ETRE TRAITE AFIN QUE LES PETITES PARTICULES ET LE SEL PRODUIT SOIENT RETIRES. APPLICATION A L'EPURATION DES EFFLUENTS GAZEUX ACIDES.THE INVENTION CONCERNS THE NEUTRALIZATION AND COOLING OF HOT ACID GASES. BEFORE THE NEUTRALIZATION OF THE GAS, THE GAS PENETS IN A CYCLONE FORMING AN UPWARD GAS SPIRAL CURRENT, SO THAT THE LARGE PARTICLES ARE SEPARATED AND CONCENTRATE ON THE CYCLONE WALL UNDER THE ACTION OF THE CENTRIFUGAL FORCES. THE UPFLOW OF GAS IS THEN IN CONTACT WITH AN UPFLOWING SPRAY OF A NEUTRALIZING LIQUID. THE PRODUCT OBTAINED CAN THEN BE PROCESSED SO THAT THE SMALL PARTICLES AND THE SALT PRODUCED ARE REMOVED. APPLICATION TO THE PURIFICATION OF ACIDIC GAS EFFLUENTS.
