Abstract

Dispositivo para la eliminación catalítica de una sustancia tóxica (NOx) contenida en el gas de escape (A) de una instalación de combustión, como por ejemplo una central térmica que funcione con combustible fósil o un motor de combustión interna, con un canal de escape de gas (8) para la conducción del gas de escape (A), con un dispositivo (10) de introducción por tobera, que está previsto para la introducción de un agente de reacción (R) en el gas de escape (A) en un espacio (4) de introducción por tobera (8) del canal (8) de escape de gas, y con un catalizador (16, 18) montado en el canal de escape de gas (8), estando configurados como silenciador el espacio (4) de introducción por tobera y un espacio de mezcla (6) situado en su caso a continuación y que está previsto para mezclar el agente de reacción (R) con el gas de escape, caracterizado porque en la dirección de paso del gas de escape (A) está situado un dispositivo mezclador (24, 26) antes ydespués del espacio (4) de introducción por tobera, y porque la distancia entre ambos dispositivos mezcladores (24, 26) está adaptada a la frecuencia del sonido que se desea amortiguar en el gas de escape (A). (Figuras 2 y 5).
