【摘要】 本文针对选择性催化还原法烟气脱硝系统进行不同导流板设置和喷氨面设置的流场模拟,以求得最佳SCR系统的设计。本文根据某电厂SCR系统的运行参数,使用GAMBIT构造几何模型并划分网格,在FLUENT中进行数值计算。研究重点在于对脱硝系统内不同的导流板设置进行流场的优化,并且对现行喷氨面设置进行验证。研究结果对脱硝系统内的导流板、喷氨面设计和改进提供了参考。更多还原

【Abstract】 It simulated the flow fields of different Deflectors setting and sprayed ammonia surfaces in selective catalytic reduction system,in order to obtain the best SCR system design.It based on operating parameters of one thermal plant SCR system,and construct geometric models and divided into grids in GAMBIT,and then numerical simulation in FLUENT. Research had focused on the deflectors setting to optimize flow field,and to validate the spray ammonia surfaces setting in SCR.The results provided references for design and improvements of deflectors and spray ammonia surfaces in the denitrification system.更多还原
