AI Technical Summary
[0003]一方面，烟气与氨气混合效率低，常因烟气局部堆积、氨气喷射分散不均，导致二者无法充分接触，进而造成氮氧化物还原不彻底，脱硝效率难以稳定达标；另一方面，气流输送过程中，若流速控制不当，易对装置内壁产生冲击磨损，且高速气流会加剧催化剂颗粒损耗，缩短设备与催化剂使用寿命，增加运维成本，同时也难以适应工况波动，影响整体运行稳定性，亟需优化结构设计以突破上述瓶颈，对此有必要提出烟气脱硝装置
[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: By synchronously driving two sets of fan blades with a single drive motor, a highly efficient collaborative operation mechanism is formed: the fan blades in the feed pipe can actively draw in the flue gas and transport it to the hemispherical collector. After being blocked by the spherical head fixing seat, the flue gas is evenly dispersed, avoiding local accumulation; the fan blades in the fixed cavity accurately draw in ammonia gas and inject it directionally into the collector area through the through hole; the two are quickly and fully mixed here, completely solving the problem of uneven mixing of flue gas and ammonia gas in traditional devices; after the mixed flue gas enters the box, it can fully and fully contact the catalyst, greatly improving the nitrogen oxide reduction efficiency and ensuring that the emission flue gas stably meets the standards; at the same time, the smooth airflow conveying and mixing process can reduce the impact and wear on the inner wall of the equipment, and also avoid the high-speed airflow from damaging the catalyst, effectively extending the service life of the equipment and catalyst, and ensuring the stable operation of the device under different operating conditions.
