Abstract

DISPOSITIVO PARA OBTENCION DE ACIDO FOSFORICO. CONSTA DE LOS SIGUIENTES ELEMENTOS: 1. UNA CUBA ADICIONAL CERRADA EN LA QUE SE INTRODUCE DE MANERA CONTINUA Y CON BARRIDO DE AIRE LA MEZCLA DE REACCION QUE SALE DEL REACTOR, APLICANDOLE UN GRADIENTE NEGATIVO DE TEMPERATURA DE 8 -+ 2. C ANTES DE REINTRODUCIRLA EN LA ZONA DE REACCION DEL REACTOR CLASICO. LA CUBA ADICIONAL FUNCIONA COMO CUBA DE TRITURACION COMPLEMENTARIA. LA INTRODUCCION DE MATERIALES EN LA CUBA ADICIONAL SE EFECTUA POR REBOSE DEL REACTOR PRINCIPAL ASI COMO POR EL FONDO. LA AGITACION EN LA CUBA SE EFECTUA POR MEDIO DE UN AGITADOR DE DOBLE TURBINA.
