Abstract:
(EN) An ammonia injection amount control method and apparatus for an activated carbon desulfurization and denitration system. The method comprises: obtaining inlet flue gas state data, outlet flue gas state data, a value of temperature and pressure compensated inlet flue gas flow, and ammonia diluting air flow; calculating a first ammonia injection amount correction value according to a preset first calculation model on the basis of the inlet flue gas state data, the outlet flue gas state data, the value of temperature and pressure compensated inlet flue gas flow, the ammonia diluting air flow, and a preset parameter; and calculating a first ammonia injection amount target value corresponding to the first ammonia injection amount correction value according to a preset second calculation model. Also disclosed is an ammonia injection amount control apparatus for an activated carbon desulfurization and denitration system.
(FR) L'invention concerne également un procédé et un appareil de commande de quantité d'injection d'ammoniac pour un système de désulfuration et de dénitration de charbon actif. Le procédé comprend les étapes consistant à : obtenir des données d'état de gaz de carneau d'entrée, des données d'état de gaz de carneau de sortie, une valeur de température et un flux de gaz de carneau d'entrée compensé en pression, et un flux d'air de dilution d'ammoniac; calculer une première valeur de correction de quantité d'injection d'ammoniac selon un premier modèle de calcul prédéfini sur la base des données d'état de gaz de carneau d'entrée, les données d'état de gaz de carneau de sortie, la valeur de température et le flux de gaz de carneau d'entrée compensé en pression, le flux d'air de dilution d'ammoniac, et un paramètre prédéfini; et calculer une première valeur cible de quantité d'injection d'ammoniac correspondant à la première valeur de correction de quantité d'injection d'ammoniac selon un second modèle de calcul prédéfini. L'invention concerne également un appareil de commande de quantité d'injection d'ammoniac pour un système de désulfuration et de dénitration de charbon actif.
(ZH) 一种活性炭脱硫脱硝系统的喷氨量控制方法和装置。方法包括:获取入口烟气状态数据、出口烟气状态数据、入口烟气流量经温压补偿后的值和氨稀释空气流量;依据入口烟气状态数据、出口烟气状态数据、入口烟气流量经温压补偿后的值、氨稀释空气流量和预设参数,按照预设第一计算模型,计算第一喷氨量修正值;按照预设第二计算模型,计算与第一喷氨量修正值相对应的第一喷氨量目标值。还包括活性炭脱硫脱硝系统的喷氨量控制装置。
