Abstract

LA INVENCION SE REFIERE A UN METODO PARA PREPARAR SOLUCIONES QUE CONTIENEN ACIDO FOSFORICO; SEGUN EL METODO, LA SOLUCION SE TRANSFORMA EN SOLIDO MEDIANTE INCORPORACION DE UN COMPUESTO DE ALUMINIO. ESTE SOLIDO ES FACIL DE ELIMINAR, PUES NO ES SOLUBLE EN AGUA. EL METODO ES PARTICULARMENTE ADECUADO PARA PREPARAR SOLUCIONES QUE CONTIENEN ACIDO FOSFORICO PROCEDENTES DEL TRATAMIENTO DE METALES. LA INVENCION TAMBIEN SE REFIERE A UN DISPOSITIVO (10) PARA APLICAR EL METODO QUE CONSTA DE UN TUBO MEZCLADOR (12) CON UN EJE LONGITUDINAL (M), UNA ENTRADA (14) Y UNA SALIDA (16). EN UNA ZONA CENTRAL SE ABREN AL MENOS DOS BOQUILLAS DE ALIMENTACION DE LIQUIDO (18 Y 20) SOBRE LA ENTRADA (14) DEL TUBO DE MEZCLA Y EN RELACION CON SU SECCION TRANSVERSAL. TAMBIEN SE ABRE EN LA ENTRADA (14) DEL TUBO MEZCLADOR AL MENOS UNA BOQUILLA DE ALIMENTACION DE GAS (22) DISPUESTA RADIALMENTE POR EL EXTERIOR DE LAS BOQUILLAS DE ALIMENTACION DE LIQUIDO (18 Y 20). EL EJE LONGITUDINAL (G) DE CADA BOQUILLA DE ALIMENTACION DE GAS (22) ESTA INCLINADO HACIA EL EJE LONGITUDINAL CENTRAL (M) DE FORMA QUE DICHOS EJES NO SE CORTAN. EL ANGULO ENTRE CADA EJE LONGITUDINAL (G) Y EL EJE LONGITUDINAL CENTRAL (M) ES DE AL MENOS 5 .
