摘　　要：以某660 MW燃煤机组烟气脱硝装置为背景,采用CFD(Computational Fluid Dynamics)仿真手段对其整流器的优化设计问题进行了研究。即给定可能的烟气和颗粒流动方向(角度),针对整流器高度、分层结构对整流效果的影响进行数值仿真。研究表明,双层错位式结构对于烟气与颗粒均有更好的整流效果。此外,还针对不同层高的双层错位式整流器进行了组合仿真,寻优得到了双层错位式整流器的最佳设计。Via CFD(Computational Fluid Dynamics) simulations,the straightener of a 660MW coal-fired power plant SCR-DeNOx facility is investigated on its structure optimization.Given possible directions(angles) of flue gas and particles,simulation is conducted focusing on the influence of height and layer structure concering the straighten effect.Simulation results show that the Two-Layer Straightener with displacement has better straighten effect on both flue gas and particles.In addition,the height of Two-Layer Straightener with displacement is optimized through simulations and the best design of this structure is obtained.
