The utility model discloses an ammonia injection grid device for SCR deNOx systems and system thereof. The ammonia injection grid device includes the ammonia injection grid body, still includes inside cavity and confined ammonia deconcentrator, the ammonia injection grid body set up in the inside of ammonia deconcentrator, just be provided with the trompil that is suitable for the ammonia diffusion on the lateral wall of ammonia deconcentrator. This system sets up the SCR deNOx systems in the boiler flue for the ammonia injection grid device. Through the device and system solve among the prior art ammonia injection grid and static mixer occupation space big, it is limited to mix the distance, for increase mix high apart from investment cost, ammonia injection grid's jet orifice block up because of urea system ammonia technology and the resistance big, the female branch pipe of managing of ammonia injection grid is numerous, the difficult scheduling problem of designing and constructing. |
