摘要
文章运用了数值模拟的方式对影响SCR催化器转化效率的部分参数进行了仿真。结果表明:SCR催化器最佳反应温度范围在180~560℃,不同尿素喷射量对转化效率有一定的影响,过少或过多尿素喷射量都会造成二次污染。安装混合器后转化效率均有10%左右的提高。
The article uses numerical simulation to simulate some parameters that affect the conversion efficiency of the SCR catalytic converter,and verifies the accuracy of the model.The optimal reaction temperature range of SCR catalyst is 180~560℃.Different urea injection quantity has certain influence on conversion efficiency.Too little or too much urea injection will cause secondary pollution.After installing the mixer,the conversion efficiency is increased by about 10%.
