Abstract

DISPOSITIF DE MELANGE D'UN GAZ AVEC DES EAUX USEES. L'EAU EST POMPEE DANS PLUSIEURS CHAMBRES DE MELANGE DANS LESQUELLES LE GAZ EST INJECTE AU DROIT D'UNE SURFACE A DECROCHEMENT DE FACON A FORMER DES COURANTS PARALLELES DE GAZ ET D'EAU. UNE CHAMBRE A PROLONGEMENT CONTIENT LES COURANTS PARALLELES ET L'INTERFACE ENTRE COURANTS DEVIENT INSTABLE CREANT DES TOURBILLONS ET PRODUISANT DES BULLES MINUSCULES QUI SE MELANGENT A L'EAU. LA CHAMBRE EST DIVISEE EN DEUX SECTIONS, LA SECTION LA PLUS ELOIGNEE DE LA SURFACE A DECROCHEMENT DIMINUANT VERS L'INTERIEUR AVEC UNE CONICITE COMPRISE ENTRE 11 ET 22, DE FACON A PERMETTRE UN FONCTIONNEMENT AVEC DES DEBITS D'AIR PLUS ELEVES SANS QUE LES TOURBILLONS FORMANT LES BULLES NE SORTENT DE LA CHAMBRE. APPLICATION AUX DISPOSITIFS D'EPURATION DES EAUX USEES.
