This invention relates to the field of flue gas purification technology, and discloses a denitrification system and method. The system includes a flue gas duct, a recovery device, a temperature control device, and a denitrification device, with the flue gas duct connected sequentially to each device. The flue gas duct is used to introduce the flue gas to be denitrated; the recovery device is used to recover moisture from the flue gas; the temperature control device is used to regulate the temperature of the flue gas; and the denitrification device is used to separate nitrogen oxides from the flue gas. This invention removes moisture from the flue gas beforehand through the recovery device, avoiding the adverse effects of moisture on the denitrification catalyst; the temperature control device regulates the flue gas to a suitable reaction temperature, improving denitrification efficiency; and the denitrification device catalytically reduces nitrogen oxides, achieving efficient and stable denitrification treatment. The entire system has a compact structure and a reasonable process, effectively avoiding ammonia escape and equipment blockage problems in traditional ammonia-based denitrification methods while achieving efficient denitrification, offering advantages such as energy saving, environmental protection, and stable operation.
