Le dispositif désodorisant selon l'invention comprend : un dispositif de chauffage pour décomposer thermiquement des composants odorants par chauffage d'un gaz résiduaire contenant des composants odorants; un échangeur de chaleur qui est disposé sur un côté du dispositif de chauffage; et un moyen d'écoulement de gaz résiduaire pour permettre au gaz résiduaire de s'écouler à travers le dispositif de chauffage et l'échangeur de chaleur, l'échangeur de chaleur comprenant : un récipient ayant un espace à l'intérieur de celui-ci; une entrée de gaz résiduaire qui est formée sur un côté du récipient; une sortie de gaz résiduaire qui est formée sur l'autre côté du récipient; et un ou plusieurs tubes d'échange de chaleur tubulaires qui sont disposés de façon à s'étendre à l'intérieur du récipient, la sortie étant reliée à une entrée du dispositif de chauffage, une extrémité du tube d'échange de chaleur étant reliée à une sortie du dispositif de chauffage, le moyen d'écoulement de gaz résiduaire étant relié à l'autre extrémité du tube d'échange de chaleur ou à l'entrée de gaz résiduaire, le gaz résiduaire étant introduit dans l'entrée de gaz résiduaire de l'échangeur de chaleur par le moyen d'écoulement de gaz résiduaire et étant déchargé vers la sortie de gaz résiduaire, et le gaz résiduaire déchargé vers la sortie de gaz résiduaire est chauffé par le dispositif de chauffage pour subir une décomposition thermique, puis est déchargé vers l'extérieur à travers le tube d'échange de chaleur.
