Optimization of SCR Denitration Reactors' Flow Field Uniformity and Design of Its Splitters

摘要

Based on CFD (Computational Fluid Dynamics), the internal flow of SCR(Selective Catalytic Reduction) denitrification column is simulated. With the application of standard k-ε two equation model and porous media model, the velocity field of smoke movement is represented. The influence rules deflector put on smoke movement can be concluded from the numerical simulation. Therefore, with adjusting the optimum combination scheme of multi splitters, the velocity deviation coefficient of first-layer catalyst is decreased to 15%.
