Zusammenfassung: | The utility model discloses a deNOx systems is united to cement kiln SNCR -SCR flue gas, including set up in the SNCR denitrification facility at the flue gas upper reaches with set up in the SCR denitrification facility in flue gas low reaches, SNCR and SCR deNOx systems sharing reductant preparation system and reductant supply control system, SNCR deNOx systems reductant injection apparatus arrange the A department on upper portion in the cement dore furnace or uptake shaft's B department, make full use of high temperature flue gas makes in reductant and the flue gas NOx take place the denitrogenation to react, SCR deNOx systems reductant injection apparatus arranges in the C1 on kiln tail pre -heater upper portion and the C department on the uptake shaft between the C2 level whirlwind section of thick bamboo. Adopted this kind of injection apparatus arrangement form economization current SNCR -SCR unite reductant pyrolysis or evaporation equipment among the deNOx systems, optimized injection system, simplified denitration technology, reduced investment cost. |
