| 摘 要： | 在SCR工艺中,氨和烟气的混合程度由烟道中的流动工况来决定。实验研究因为设备尺寸的原因而受到限制。将计算流体力学软件(CFD软件)引入到SCR系统的设计中,利用计算机的运算功能对SCR系统烟道内的流动情况进行模拟。通过模拟,对SCR反应器及其连接烟道的速度、压力、氨浓度分布进行分析,以优化烟道和反应器的设计,使烟气和氨的分布最均匀,并使进出口的压差最小,从而完善了SCR系统设计。

| Abstract: | In the selective catalytic reduction (SCR) process,the mixing uniformity of ammonia and flue gas is determined by the flowing state.Because of the limitation in dimension of experimental equipment,the Computational Fluid Dynamic (CFD) software is used to simulate the flowing state of flue gas in design of SCR system.Through simulation,the velocity,pressure,concentration distribution in the reactor and its connecting ducts in SCR system are analyzed and their designs are optimized.The uniform distribution of... |
