Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA PREPARACION DE FOSFATOS DE METALES ALCALINOS. SE SOMETEN A ATOMIZACION SOLUCIONES O SUSPENSIONES DE FOSFATOS DE METALES ALCALINOS EN UNA TORRE (1) MEDIANTE POR LO MENOS UNA BOQUILLA A TRAVES DE UNA ZONA DE LLAMAS GENERADA POR UNA CORONA DE QUEMADORES (11). EL DISPOSITIVO CONSTA DE LA MENCIONADA TORRE DE ATOMIZACION (1) CERRADA CON UNA TAPA (2), ESTANDO ATRAVESADA DICHA TAPA POR UN TUBO DE APORTACION (5) DE SOLUCION COMUNICADO CON UNA DISPOSICION DE ATOMIZACION Y ESTANDO ATRAVESADA TAMBIEN LA TAPA POR VARIOS QUEMADORES (11) DISPUESTOS CONCENTRICAMENTE EN TORNO AL TUBO DE APORTACION DE SOLUCION. CONSTA ASIMISMO DE UN TUBO DE ALIMENTACION (15) Y AL MENOS UNA CABEZA DE ATOMIZACION (12) EN CUYA SUPERFICIE HORIZONTAL ESTAN EMPOTRADAS VARIAS BOQUILLAS PARA UNA SOLA SUBSTANCIA. EN EL TUBO DE APORTACION DE SOLUCION SE ENCUENTRA AL MENOS UNA BOMBA (7) DE ACRECENTAMIENTO DE LA PRESION.
