Abstract

DISPOSITIVO DE DESCONTAMINACION DE SUPERFICIE (3) DE UN MATERIAL (2), EN EL QUE SE FIJA O DISPONE CUALQUIER PARTICULA QUE COMPRENDE COMPONENTES DE CONTAMINANTES DETERMINADOS Y QUE SON OBJETO DE DICHA LIMPIEZA: EL DISPOSITIVO COMPRENDE AL MENOS UN HAZ LASER (1) PULSADO PROYECTADO POR CUALQUIER MEDIO (13, 14) EN DICHA SUPERFICIE (3) Y ELEGIDO EN UNA GAMA DE LONGITUD DE ONDA ULTRAVIOLETA COMPRENDIDA ENTRE 190 Y 360 NANOMETROS; DICHO DISPOSITIVO DE LIMPIEZA COMPRENDE UNA BOCA DE ASPIRACION (9) QUE RODEA DICHO HAZ LASER (1) SEGUN SU EJE XX'' Y TODO EL SISTEMA PERMITA EL DESPLAZAMIENTO DEL CONJUNTO RELATIVAMENTE CON RESPECTO A DICHA SUPERFICIE (3) QUE HAY QUE LIMPIAR SEGUN UN TRAZADO DETERMINADO DE DICHO HAZ LASER (2) PARA TRATAR ESA SUPERFICIE, EXPULSANDO POCO A POCO, DICHAS PARTICULAS ARRANCADAS POR EFECTO DE ABLACION A ESTA SUPERFICIE FORMANDO UN PENACHO (7) POR ENCIMA DE ESTA, EN EL QUE SE CAPTA LA EMISION OPTICA Y SE MIDE LA INTENSIDAD DE FRECUENCIAS DE EMISION OPTICAS DE DICHOS COMPONENTES DE CONTAMINANTES DETERMINADOS. UNA DE LAS APLICACIONES PRINCIPALES ES LA DESCONTAMINACION DE SUPERFICIES DE LOCALES, DE EQUIPOS, DE TUBERIAS, ETC... CONTAMINADAS POR RADIOELEMENTOS O ELEMENTOS QUIMICOS.
