Background technique
Current, the whole world faces the comprehensive challenge of the energy and environment.Aspect the technological means selection of the emission compliance of orthodox car, people still face many difficult problems, for example, and the aspects such as technical approach of How to choose reprocessing.
SCR (Selective Catalytic Reduction) catalyzed conversion reduction technique is traditional post-processing technology.The essence of traditional SCR technology of this employing liquid area is to utilize urea at high temperature to decomposite ammonia, reacts under the comprehensive function of catalyzer and temperature as ammonia and the NOX in the engine exhaust of reducing agent, generates nontoxic N under the desirable operating mode
2And H
2O, thus reach the purpose of purification.
Traditional SCR has lot of advantages, for example, can have 50 ~ 85% NOX removal efficient in the scope of delivery temperature 250 ~ 550oC, and can effectively reduce the emission level of PM; Traditional SCR can easily satisfy Europe 4 and Europe 5 levels, also has the potentiality that reach Europe 6 levels; Reach at present traditional SCR technology that adopt in Europe 4, the fuel oil consumption of motor can reduce by 3 ~ 6%; Traditional SCR catalyzer does not contain precious metal, and is more relatively low than cost; Traditional SCR is to the quality of fuel oil for vehicles, and particularly Sulpher content is insensitive.Based on above analysis, traditional SCR post-processing technology also relatively is fit to vehicle condition and the fuel oil for vehicles situation of China.
If apply traditional vehicle-mounted SCR post-processing technology in China, must resolve carrier, catalyzer, carbamide reducing agent and add the dosage of supply network, carbamide reducing agent, the vital technological difficulties such as atomized spray, SCR catalyzer conversion efficiency, ammonia amount of leakage and system matches of carbamide reducing agent.
