Abstract

Une tour de récupération de chaleur perdue de gaz de combustion multifonctionnelle intégrée, qui est utilisée pour la récupération et l'utilisation de chaleur perdue de gaz de combustion provenant de fours dans des centrales électriques de cogénération. Le gaz de combustion pénètre dans un corps de tour de récupération (3) à partir d'une entrée de gaz de combustion, passe à travers une couche de pulvérisation de désulfuration (5), puis s'écoule de façon régulière à travers un distributeur de gaz de combustion (7) vers une couche de pulvérisation de désulfuration (8). Un désembueur (9) est disposé au-dessus de la couche de pulvérisation de désulfuration (8), et un orifice d'échappement relié à un tuyau de gaz de combustion s'étendant dans une cheminée (25) est disposé au-dessus du désembueur (9). La tour de récupération de chaleur perdue est également reliée à un échangeur de chaleur à plaques (30), ce qui réduit la température de l'eau de pulvérisation en circulation entrant dans la tour de récupération de chaleur perdue. L'eau de retour provenant d'un réseau de chauffage est chauffée par l'échangeur de chaleur à plaques (30) puis entre dans un dispositif de chauffage de réseau de chauffage pour un chauffage supplémentaire, et est envoyée au réseau de chauffage lors de l'atteinte des exigences de fonctionnement. La tour de récupération de chaleur perdue de gaz de combustion multifonctionnelle intégrée peut simultanément effectuer une dénitrification, une désulfuration, une élimination de poussière et une récupération de condensat sur un gaz de combustion, ce qui permet d'économiser de l'espace de sol et de réduire les coûts d'investissement et d'exploitation.
