Abstract

SE PRESENTAN UN DISPOSITIVO Y UN METODO DE CONTROL DE LAS EMISIONES PARA TRATAR LOS GASES DE ESCAPE Y REDUCIR LOS CONTAMINANTES GASEOSOS QUE CONTIENEN. EL DISPOSITIVO INCLUYE UNA CAMARA DE TRATAMIENTO (12) A TRAVES DE LA CUAL PASAN LOS GASES DE ESCAPE. DENTRO DE LA CAMARA HAY COLOCADAS UNA PRIMERA Y UNA SEGUNDA PANTALLAS METALICAS (18, 20) DISPUESTAS A UNA DISTANCIA PREDETERMINADA UNA DE LA OTRA. ENTRE LAS PANTALLAS HAY COLOCADA UNA SECCION DE UN SUSTRATO QUIMICO (19). SE APLICA UNA TENSION AL LADO DE LA PRIMERA PANTALLA (18) CON, POR EJEMPLO, UN DISPOSITIVO DE ELECTRODO (24). HAY UN CIRCUITO TEMPORIZADOR (38) PARA EXCITAR POR IMPULSOS LA TENSION A UN RITMO DE LOS IMPULSOS PREDETERMINADO. SE PUEDE COLOCAR UN DISPOSITIVO SENSIBLE A LA TEMPERATURA (42) ENTRE LA CAMARA DE TRATAMIENTO (12) Y EL CIRCUITO TEMPORIZADOR (80) PARA QUE LA TENSION EXCITADA POR IMPULSOS SOLO SEA SUMINISTRADA A LA PANTALLA (18) DENTRO DE UNA GAMA DE TEMPERATURAS PREDETERMINADA.
