The utility model discloses a
flue gas denitration device, which relates to the technical field of
flue gas denitration and comprises a treatment tank, a
liquid storage tank and a liquid collecting cover, the liquid collecting cover is fixedly mounted in the treatment tank, a plurality of liquid spraying pipes are arranged at the bottom of the
liquid storage cover, vent holes are formed between two liquid spraying pipes in a row of liquid spraying pipes, and the
liquid storage tank is fixedly mounted on the treatment tank; the interior of the
liquid storage tank is divided into two cavities for containing a denitration
ammonia water solution and water through a partition plate, the liquid collection cover is fixedly connected with a first liquid guide
pipe and a second liquid guide
pipe, and the first liquid guide
pipe and the second liquid guide pipe both penetrate through the treatment tank and extend into the two cavities of the
liquid storage tank correspondingly; the technical problems that the interior of an existing
flue gas denitration device is inconvenient to clean, the denitration efficiency is affected for a long time,
smoke and an
ammonia water solution are not prone to being in full contact, the
reaction speed is low, and the purification effect is poor are effectively solved.
