Abstract:At present, the number of domestic factories is increasing,resulting in higher and higher requirements for the environment. In view of the current domestic factory flue gas problem, many domestic experts have studied the technology of flue gas desulfurization and denitration, and gradually improved the stability of flue gas desulfurization and denitration technology, provided certain basic conditions for environmental protection, and provided a guarantee for the sustainable development of enterprises. This paper discusses the development status of desulfurization and denitration technology, analyzes common technologies, and finally puts forward relevant strategies for energy conservation and environmental protection of desulfurization and denitration technology from various angles, providing a certain basis for improving the operation efficiency of thermal power plants and paying attention to environmental protection.

1煙气脱硫脱硝技术的发展现状
目前排污高效的技术就是湿法烟气脱硫脱硝技术,这项技术的原理是首先将烟气输送到scr设备当中,通过设备中的催化剂利用化学反应,将一氧化氮转换成氮气,然后将烟道中的气体输送到改质器中,有害的二氧化硫气体会在催化剂的作用下转换成一氧化硫,气体经过冷凝器的过滤冷凝,与冷凝水进行结合,就会产生浓度较高的硫酸,避免给火电厂造成影响,因此采用湿法技术可以明显提高脱硫脱硝的效果,并且可以保证整体工作的稳定性和安全性,但是相对于其他脱硫脱硝的技术来说,此方法的成本较高,并且过滤后产生的浓硫酸不易存储,易对设备造成腐蚀,还易造成泄漏等,所以该项技术在国内没有得到广泛的应用。……
