摘要：

In this paper, in order to optimize the denitrification efficiency and equipment structure of selective catalytic reduction (SCR) flue gas denitrification technology, a mathematical model of the internal flow field of SCR system was established according to the principle of fluid mechanics. The ICEM software was used to complete the grid generation, to process boundary conditions and to create the 3d models. The Simple algorithm is adopted for the coupling of speed and pressure. The flow in the reactor is turbulent flow and is simulated by standard K - e model. The main conclusions can be summarized as follows: (1) Through the construction and calculation of the flow field model of the denitration system, the optimized SCR denitration reactor model and its performance distribution characteristics were obtained. (2) In the SCR denitration reactor installed with the porosity type nozzle, the pressure distribution at the inlet changed little and was more uniform, and the nozzle of porosity type can effectively prevent ash accumulation and blockage and improve the uniformity of distribution.
