| titleOfInvention | A kind of cement kiln flue gas desulphurization system and method |
| abstract | A kind of cement kiln flue gas desulphurization system and method, including tank used for storing ammonia, delivery pump, ejecting gun, cement decomposing furnace, cement kiln precalcining system and automatic control system, cement kiln precalcining system includes multistage preheater, the tank used for storing ammonia is connected to by delivery pump with ejecting gun, and the spray site of ejecting gun is located at the exit of second level preheater windspout barrel.The method of the desulfurization, the ammonium hydroxide including one, configuration 15%-25%；Two, real-time detection SO 2 Concentration, according to SO in flue gas 2 Concentration is calculated, the amount of injection of adjustment ammonium hydroxide by automatic control system；Three, according to the ammonia water spray amount being calculated in step 2, ammonium hydroxide is injected in cement kiln precalcining system after injecting jet rifle after delivery pump is pressurized, injection is located at the exit of cement kiln second level preheater windspout barrel.For inventive desulfurization efficiency up to 95% or more, desulfuration efficiency is high, and ratio of ammonia-sulfur is 2~2.5, and operating cost is low. |
