The utility model provides a system for dust and NOx minimum discharge under high temperature can realize the dust under the high concentration dusty environment, NOx's minimum discharge, simultaneously can high -efficient desorption SO2, SO3, HCl, HF, and the area of whole system is little, operating power consumption low, nos wastewater discharge, the environment index advanced person. It is including in proper order by economizer, fluidized bed reactor, cyclone, ammonia injection grid, denitration gas wash tower, air heater, draught fan and the chimney of flue intercommunication to and desulfurizer supply system and ammonia supply system, upper reaches flue is connected to fluidized bed reactor's gas access, and solid inlet port connects the output of desulfurizer supply system, and cyclone's air inlet is connected to the exhanst gas outlet, grey storehouse goes out the solid inlet port that grey device was connected to fluidized bed reactor in the middle of cyclone's the grey antilinear of row, ammonia injection grid arranges in the flue that the ammonia supply system is connected to its input. |
