Abstract

La invención se refiere a un purificador de gas que comprende un medio de filtración con acción fotocatalítica, un sistema para la iluminación UV del medio, un medio de demora o un analizador de un compuesto orgánico volátil, un medio para ajustar automáticamente la velocidad del gas que fluye a través de él o para ajustar la intensidad de la iluminación UV, el ajuste se realiza con base en el tiempo determinado por el medio de demora con base en el contenido del compuesto orgánico volátil analizado por el analizador. La invención también se refiere a un método para la purificación de un gas utilizando un purificador que comprende un medio de filtración con acción fotocatalítica y un sistema para la iluminación UV del medio, de acuerdo con el cual, cuando la concentración de un compuesto en el gas es más alto que un valor V1, el modo de operación del purificador es inferior a la de su modo cuando la concentración del compuesto en el gas es inferior a un valor V2, V2 es inferior o igual a V1. La invención también se refiere a un método para la purificación de un gas utilizando un purificador que comprende un medio de filtración con acción fotocatalítica, un sistema para la iluminación UV del medio, y un medio de demora para controlar el modo del purificador.
