Abstract

L'invention concerne un appareil de système de récupération, de traitement et de conversion de gaz d'échappement, comprenant : une cartouche de gaz d'échappement (1), un incinérateur (2), un réacteur R-200 (3), un refroidisseur (5), un réacteur R-500 (6), une cartouche de stockage d'acide sulfurique (7), un condenseur C-300 (9), une chambre de combustion (16), et un réservoir de drainage d'eau (20). L'incinérateur (2) est disposé sur un côté de la cartouche de gaz d'échappement (1). Le réacteur R-200 (3) est disposé sur un côté de l'incinérateur (2). Un conduit (10) est disposé à une extrémité du réacteur R-200 (3). Le condensateur C-300 (9) est disposé sur un côté du réacteur R-200 (3). Le refroidisseur (5) est disposé sur un côté du condenseur C-300 (9). Un ventilateur de condenseur C-300 (4) est disposé au niveau d'une partie inférieure du condenseur C-300 (9). Le réacteur R-500 (6) est disposé sur un côté du refroidisseur (5). Le gaz d'échappement contenant du H2S est d'abord traité à haute température et est oxydé avec de l'oxygène pour former du SO2 gazeux et de l'eau. Le gaz SO2 est ensuite oxydé davantage en présence d'un catalyseur, tel que le platine, pour former un gaz SO3. La réaction est facile et hautement efficace, empêchant le problème de production de divers sous-produits contenant du soufre. Le gaz SO3 se lie à la vapeur d'eau et est condensé en acide sulfurique au cours d'un processus de refroidissement. De plus, une partie du gaz résiduaire qui est condensée peut être en outre catalysée en H2SO4, ce qui empêche le problème de pollution environnementale provoquée par le gaz résiduaire résiduel.
