Abstract

UN SISTEMA DE ESTERILIZACION DE AGUA POR RAYOS ULTRAVIOLETAS COMPRENDE UNA CAMARA DE TRATAMIENTO ALARGADA (10) QUE TIENE UNA LAMPARA DE ULTRAVIOLETA AXIAL (14) DISPUESTA PARA EMITIR LUZ CON UNA LONGITUD DE ONDA DE ENTRE 245 Y 265 NM. LA TEMPERATURA DE LA PARTE EXTERIOR DE LA LAMPARA (14) SE MANTIENE EN UN NIVEL CONSTANTE MEDIANTE UN VENTILADOR Y/O UN CALENTADOR, QUE SON CONTROLADOS POR SENSORES DE TEMPERATURA (21, 22). UN MICROPROCESADOR (28) CALCULA LA DOSIS DE RADIACION SUMINISTRADA AL AGUA A PARTIR DEL PRODUCTO DE LA INTENSIDAD DE LOS RAYOS ULTRAVIOLETA Y DEL TIEMPO DE EXPOSICION. LA INTENSIDAD DE LOS RAYOS ULTRAVIOLETAS SE MIDEN UTILIZANDO UNA CABEZA DE UN FOTODETECTOR (23) MONTADA EN EL LADO DE LA CAMARA (10). LA CABEZA DEL FOTODETECTOR (23) COMPRENDE UN FOTODIODO DE VACIO DE DESVIACION INVERSA QUE ACTUA COMO SENSOR PARA LA LUZ UV EN LA LONGITUD DE ONDA DE ENTRE 245 Y 265 NM.
