Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA FLOTACION. LA MEZCLA A SEPARAR SE INTRODUCE EN UNA CELDA DE FLOTACION, DONDE SE TRATA CON GAS, PREFERENTEMENTE AIRE, MEDIANTE UNA TOBERA. EN EL EJE DEL CHORRO PROPULSOR SE DISPONE UN ELEMENTO DE DEFLEXION EN FORMA CONICA, DE ANGULO COMPRENDIDO ENTRE 90 Y 120 GRADOS. MODIFICANDO LA DISTANCIA ENTRE EL ELEMENTO DEFLECTOR Y LA CARCASA SE VARIA EL COMPORTAMIENTO A SUCCION DE LA TOBERA Y LA ENERGIA CINETICA DEL CHORRO LIBRE. EL SOLIDO FLOTANTE SE ACUMULA EN LA COBERTURA INCLINADA Y ES EXTRAIDO AUTOMATICAMENTE AL SER IMPULSADO DESDE ABAJO POR LA ESPUMA. DE ESPECIAL APLICACION EN LA PURIFICACION DE AGUAS RESIDUALES EN LAS INDUSTRIAS QUIMICAS.
