Abstract

LA PRESENTE INVENTION CONCERNE LE TRAITEMENT DES LIQUIDES PAR FLOTTATION. ELLE PROPOSE UNE CELLULE DE FLOTTATION AVEC UNE CUVE VERTICALE, UN DISPOSITIF POUR PRODUIRE DES BULLES DANS LA CUVE, UN SYSTEME D'EVACUATION DE MATIERES SOLIDES, DANS LAQUELLE LA CUVE EST PARTAGEE PAR UNE CLOISON INCLINEE EN DEUX CHAMBRES QUI COMMUNIQUENT AU NIVEAU DE LA PARTIE HAUTE DE LA CLOISON, LA CHAMBRE BASSE DANS LAQUELLE SONT FOURNIES LES BULLES ETANT MUNIE D'AU MOINS UNE CANALISATION D'AMENEE DE LIQUIDE A TRAITER, LA CHAMBRE HAUTE ETANT MUNIE D'AU MOINS UNE CANALISATION D'EXTRACTION DE LIQUIDE CLARIFIE QUI PREND NAISSANCE A UN NIVEAU INFERIEUR A CELUI DE LA COMMUNICATION ENTRE LES DEUX CHAMBRES. LA PRESENTE INVENTION EST UTILISEE POUR CLARIFIER DES LIQUIDES CHARGES ET POUR EPAISSIR LES BOUES RASSEMBLEES EN SURFACE ET CONSTITUEES PAR LES DECHETS CHARGEANT INITIALEMENT CES LIQUIDES.THE PRESENT INVENTION CONCERNS THE TREATMENT OF LIQUIDS BY FLOTATION. IT OFFERS A FLOTATION CELL WITH A VERTICAL TANK, A DEVICE FOR PRODUCING BUBBLES IN THE TANK, A SOLID MATERIAL EVACUATION SYSTEM, IN WHICH THE TANK IS SHARED BY AN INCLINED BULKHEAD IN TWO ROOMS THAT COMMUNICATE AT THE LEVEL OF THE PART HIGH OF THE BULKHEAD, THE LOW CHAMBER IN WHICH THE BUBBLES ARE PROVIDED IS EQUIPPED WITH AT LEAST ONE PIPING FOR DELIVERY OF LIQUID TO BE TREATED, THE UPPER CHAMBER IS EQUIPPED WITH AT LEAST ONE PIPE FOR EXTRACTING CLARIFIED LIQUID WHICH IS PROVIDED AT A LEVEL LOWER THAN THAT OF THE COMMUNICATION BETWEEN THE TWO BEDROOMS. THE PRESENT INVENTION IS USED TO CLARIFY CHARGED LIQUIDS AND TO THICKEN THE SLUDGE GATHERED ON THE SURFACE AND CONSTITUTED BY WASTE INITIALLY CHARGING THESE LIQUIDS.
