Construction Of Src Denitration Intake Pipeline
Posted by: Date:21.Dec.2022
SRC denitrification process
The process design sequence of SCR flue gas denitrification is: boiler - fan - SCR denitrification - emptying. The flue gas is fully mixed with ammonia gas in the pipeline and then flows into the SCR reactor. A flue gas guide baffle is added at the inlet of the SCR reactor to make the gas flow into the SCR reactor evenly distributed, and the flow rate is properly regulated to ensure the catalyst. utilization rate. The position of the reducing agent spray gun and the form of the nozzle are designed according to the layout of the flue, so as to ensure the efficiency and economy of denitrification, and prevent the secondary pollution of equipment and air caused by excessive local ammonia injection. After the flue gas entering the reactor passes through the catalyst, the nitrogen oxides are decomposed and discharged after reaching the standard. Because the catalyst adopts honeycomb mode, the turbulence increases the contact between the mixed gas and the catalyst, and the conversion rate is high, and the excess ammonia gas will stay in the module to participate in the conversion of unreacted tail gas, so the ammonia escape rate is low.
