Abstract

La présente invention a pour but de résoudre de manière fondamentale des problèmes de fuite provoqués par une abrasion de parties rotatives d'oxydateurs thermiques régénératifs de type à disque rotatif classiques. L'oxydateur thermique régénératif de la présente invention comprend une chambre de distribution d'admission/échappement d'air ayant des soupapes à fonctionnement cyclique et est configuré de sorte qu'un réservoir de stockage thermique ayant une matière de stockage thermique stockée dans celui-ci soit divisé en sections correspondant au nombre de soupapes. Ainsi, les gaz nocifs sont introduits à travers une section du réservoir de stockage thermique, et les gaz propres obtenus après combustion sont évacués à travers une autre section du réservoir de stockage thermique. De plus, l'alimentation en gaz de purge est réalisée en continu et de manière alternée pour améliorer le rendement d'élimination de contaminants. En conséquence, le rendement d'utilisation de l'oxydateur thermique régénératif est rendu maximal tout en empêchant de manière fondamentale les gaz nocifs avant traitement et des gaz propres après traitement d'être mélangés.
