•GASES LIMPIOS (BR010): Conducto salida a chimenea3.- SISTEMA DOAS IN SITU CROSS STACK: PRINCIPIO DE MEDIDA

Sistema de monitorización en continuo

Su principio de medida se basa en la absorción de la luz que recorre un determinado camino óptico debida a los contaminantes atmosféricos presentes en ese recorrido.

Ley de Lambert-Beer que establece la relaciónentre la cantidad de luz absorbida y el número de moléculas presente en el recorrido de la luz.

•GASES LIMPIOS (BR010): Conducto salida a chimenea3.- SISTEMA DOAS IN SITU CROSS STACK: HUELLA ESPECTRAL

• Para seleccionar la longitud de onda, un disco giratorio (que permite una resolución de 0,4 nm) se coloca frente al fotomultiplicador que detecta la intensidad luminosa, y la convierte en una señal digital que puede ser almacenada en la unidad central.

• El espectro atmosférico medido se usa para obtener el espectro diferencial

• A partir de la correlación múltiple entre el espectro medido y los valores pregrabados: HUELLA ESPECTRAL de los gases atmosféricos que absorben en la misma región del espectro se determinan las concentraciones, que son almacenadas en el ordenador junto a sus desviaciones estándar y niveles de luz.

COMPONENTES PRINCIPALESEMISOR:

Equipado con una lámpara de xenon a alta presión que emite luz en longitudes de onda en el espectro visible, ultravioleta, e infrarrojo y un espejo parabólico que actúa como colimador.

RECEPTOREquipado con un espejo que focaliza la luz recibida hacia una fibra óptica que conduce el haz luminoso hacia una red de difracción ubicada en la Unidad central.

ANALIZADORSistema compuesto por fotodetectores y fotomultiplicadores que permite, junto al software adecuado, evaluar y analizar la perdida de luz debido a la absorción molecular que se produjo en el camino recorrido, y en función de dicha longitud obtener las concentraciones de los elementos atmosféricos deseados.
