The utility model discloses a kind of ammonia-spraying grid device, including：Multiple spray ammonia main pipes (1), multiple spray ammonia main pipes (1) are disposed in parallel in the same section of flue gas flow direction；Multiple spray ammonia branch pipes, it is connected with spray ammonia main pipe (1), multiple spray-holes are provided with spray ammonia main pipe (1), spray ammonia branch pipe is inserted perpendicularly into spray ammonia main pipe by spray-hole respectively, and ammonia is sprayed to be mixed with flue gas from spray ammonia main pipe by spraying the diffusion of ammonia branch pipe.A kind of ammonia-spraying grid device of the present utility model, ammonia can be effectively facilitated and mixed with the diffusion of flue gas, improve ammonia concentration field distribution, improve reaction efficiency；Mixing ammonia is sprayed from spray ammonia main pipe by spraying ammonia branch pipe, and the positive effect that mixing ammonia is diffused by spraying ammonia branch pipe, the ammonia of ejection be able to can be sufficiently mixed with flue gas by short distance, and ammonia concentration distribution is visibly homogeneous. |
