AI Technical Summary
Technical Problem
In existing SCR denitrification systems, the mixing effect between ammonia and flue gas is poor, resulting in incomplete reaction and weakening the denitrification efficiency of the system.
Method used
It adopts a two-stage mixer structure, including an ammonia injection grid module and a wind cap nozzle, as well as a mixer module. The mixing uniformity of ammonia and flue gas is improved through primary and secondary mixing. The modular design can be adapted to different working conditions.
Benefits of technology
It improves the mixing efficiency and uniformity of ammonia and flue gas, ensuring the denitrification effect of the SCR denitrification system, and is applicable to different flue gas ammonia injection denitrification retrofit projects.

Abstract
本申请公开了一种用于SCR脱硝的喷氨混合装置，属于烟气环保脱硝装置技术领域。通过在用于SCR脱硝的喷氨混合装置中设置两级混合器结构，也即是配合的喷氨格栅模块和风帽式喷嘴组成一级混合结构，混合器模块组成二级混合结构，使得烟气与氨气混合气体的混合距离短，混合效率高。并且整体采用模块化设计，通过喷氨格栅模块与混合器模块的层级对应关系，实现精准的氨气分布与混合效果，能够适用于不同工况的烟道喷氨脱硝改造工程。在实际应用中，SCR脱硝系统可采用上述模块化设计，沿烟道深度方向分区布置，可灵活调节模块数量以适应不同机组烟气量变化需求。
