摘　　要：为了改善选择性催化还原(SCR)脱硝反应器内烟气与氨气的混合效果,提出3种导流板布置方案,应用数值模拟方法分析了导流板布置方式对SCR反应器内烟气流场与氨浓度分布的影响。分析结果表明:不同的导流板布置方式对烟气与氨气混合效果具有重要影响,采用3块导流板不均匀布置的方案具有最佳的混合效果。In order to improve the mixing effect of the flue gas and ammonia in SCR（ selective catalytic reduc- tion） denitration reactor, three layout methods for deflectors are proposed. A numerical simulation has been applied for the study on the field of flue gas and ammonia distribution under different layout methods of deflectors in the SCR reactor. The results show that different layout types of flow deflectors have important influence on the mixing of flue gas and ammonia,and program 3 has the best mixing results.
