Abstract
ESTA INVENCION SE REFIERE A UNA CUBA DE PRECIPITACION PERFECCIONADA PARA SU UTILIZACION EN LA PRECIPITACION DE ALUMINA EN EL PROCESO BAYER. ESTA INVENCION CONSTA DE UN TANQUE CON FONDO Y PAREDES QUE DEFINEN UN VOLUMEN INTERIOR PARA CONTENER UN FLUIDO. EL TANQUE TIENE MONTADO EN SU INTERIOR UN TUBO DE DESCARGA QUE INCLUYE LOS ELEMENTOS PARA HACER CIRCULAR EL FLUIDO, UNA COLUMNA CILINDRICA QUE TIENE UNOS EXTREMOS PRIMARIOS Y SECUNDARIOS, UNA ENTRADA DE FLUIDO EN DICHO EXTREMO PRIMARIO Y UN NUMERO DE PATAS CON ABERTURAS ADYACENTES A DICHOS EXTREMOS SECUNDARIOS. EL TUBO DE DESCARGA TAMBIEN DISPONE DE UN INTERCAMBIADOR DE CALOR QUE INCLUYE UNA DIVERSIDAD DE ELEMENTOS DEL INTERCAMBIADOR DE CALOR QUE ESTAN DISPUESTOS RADIALMENTE EN EL INTERIOR DE LA COLUMNA CILINDRICA DEL TUBO DE DESCARGA. CUANDO UN LODO QUE CONTIENE PARTICULAS ABRASIVAS SE HACE CIRCULAR A TRAVES DEL TUBO DE DESCARGA, DICHAS PARTICULAS LIMPIAN LA SUPERFICIE DEL INTERCAMBIADOR PARA PREVENIR LA ACUMULACION DE PARTICULAS EN LA SUPERFICIE DEL INTERCAMBIADOR DE CALOR.
