Abstract

EL OBJETIVO DE ESTE INVENTO ES UN METODO PARA EL TRATAMIENTO FOTOCATALITICO DE MEZCLAS ACUOSAS DE SUSTANCIAS CONTAMINANTES. DICHO METODO CONSISTE EN SOMETER TALES MEZCLAS A IRRADIACION, EN PRESENCIA DE DIOXIDO DE TITANIO, MIENTRAS ESTAN CIRCULANDO DENTRO DEL REACTOR (A), FORMADO POR UN ESPACIO HUECO DE NO MAS DE 5 CM DE ESPESOR, CUYA PARED INTERIOR ES LA PARED DE UNA LAMPARA (C), QUE EMITE POR LO MENOS UNA FRACCION DE SU RADIACION CON UNA LONGITUD DE ONDA MENOR DE 400 NM. EN ESTE REACTOR NO HAY REVESTIMIENTO REFRIGERADOR ENTRE LA LAMPARA Y LA MEZCLA DE REACCION, PERO EL CONTROL DE LA TEMPERATURA SE REALIZA POR MEDIO DE LA CIRCULACION DE LA MEZCLA DE REACCION DENTRO DEL REACTOR.
