The utility model discloses an internal contraction shape circular cone expands liquid ammonia NH3 spray set, nozzle are the form that tightly connects the circular cone diffuser behind the circular cone contraction section. The utility model discloses rational in infrastructure, along the circular cone shape diffusion when reinforcing liquid ammonia NH3 jets out from the nozzle, overcome high air current in the flue, high negative pressure, about from about, in the all -round no dead angle degree of depth and the flue gas nitrogen oxide NOx advancing the mixture, reach the reduction and does not participate in the possibility that the liquid ammonia NH3 of reaction escaped to improve denitrification facility efficiency. |
