| titleOfInvention | Grate-rotary kiln pelletizing flue gas classification denitrification facility |
| abstract | The utility model relates to a grate-rotary kiln pelletizing flue gas hierarchical denitrification facility, prepare the system including the reductant, first order SNCR deNOx systems, second level SCR deNOx systems, third level flue gas governing system, the grate divide into dry one section, dry two-stage section, preheat one section, preheat the two-stage section, it sets up first order SNCR deNOx systems to connect the changeover portion at rotary kiln tail and grate, the reductant atomization that the system was prepared to the reductant is spouted into first order SNCR deNOx systems, set up second level SCR deNOx systems between grate multitube dust remover and backheat fan, its characterized in that: a third-stage flue gas adjusting system is arranged at the preheating section of the chain grate, which is close to the outlets of 1-3 air boxes at the preheating section, and the flue gas outlet of the third-stage flue gas adjusting system is connected with the flue gas inlet of the multi-pipe dust remover. The device provided by the utility model have hierarchical accurate, only carry out denitration treatment to the flue gas that nitrogen oxide concentration is high, have that denitration efficiency is high, the ammonia escape is low, construction investment and running cost are low advantage. |
