Abstract

PROCEDE ET APPAREIL POUR SEPARER UNE MATIERE EN PARTICULES D'UN FLUIDE. LE PROCEDE ET L'APPAREIL DE L'INVENTION IMPLIQUENT LE PASSAGE D'UNE DISPERSION D'UNE MATIERE EN PARTICULES DANS UN FLUIDE A TRAVERS UN MODULE TUBULAIRE SOLIDE POREUX 1 QUI PEUT RETENIR LA MATIERE EN PARTICULES MAIS PERMET LE PASSAGE DU FLUIDE. LE PROCEDE ET L'APPAREIL DECRITS SONT SPECIALEMENT UTILES POUR LAVER ETOU AJUSTER LA CONCENTRATION DE MATIERES EN PARTICULES AYANT UNE DISTRIBUTION GRANULOMETRIQUE COMPRISE ENTRE ENVIRON 0,1 ET 50M DISPERSEES DANS DES FLUIDES PAR RECYCLAGE DE LA DISPERSION A TRAVERS LE MODULE TUBULAIRE POREUX AYANT UN DIAMETRE DE PORES COMPRIS ENTRE ENVIRON 0,5 ET 5M JUSQU'A CE QUE LA CONCENTRATION DE LA MATIERE EN PARTICULES DISPERSEES AUGMENTE JUSQU'A ATTEINDRE UNE VALEUR PREDETERMINEE.
