火电厂烟气脱硫脱硝一体化技术探析

Analysis on Integrated Technology of Flue Gas Desulfurization and Denitrification in Thermal Power Plants

现阶段我国的电能绝大部分还是通过火力发电而获得,火电厂用来发电而使用的燃料还是煤炭,众所周知煤炭内含有大量的硫元素与氮元素,硫元素与氮元素经过燃烧之后发生化学反应生成SO2气体与多种氮氧化物。SO2本身就是有害的气体。如果不对这些物质进行处理而直接将烟气排放,必然会对人民群众与生态环境造成非常严重的伤害。所以对于烟气中所含有的SO2气体以及氮氧化物进行处理已经成为现阶段我国火电厂所必须要面对的问题,对火电厂产生的烟气进行脱硫脱硝处理可以有效保护生态环境,降低污染情况。随着经济及科技的高速发展,人们对于生态环境的保护越来越重视,怎样可以有效地进行火电厂烟气脱硫脱硝的处理,已经成为众多业内相关工作人员最重要的一项研究项目。本文对现阶段我国火电厂烟气脱硫脱硝一体化处理技术的相关原理进行简单的讨论,对比得出烟气脱硫脱硝一体化技术所存在的一些优势,希望可以为从事火电厂烟气脱硫脱硝工作的相关人员提供一定的帮助。

At present, most of China’s electricity is still obtained through thermal power generation. The fuel used by thermal power plants to generate electricity is still coal. It is known that coal contains a lot of sulfur and nitrogen, and sulfur and nitrogen are burned. The chemical reaction produces sulfur dioxide gas and various nitrogen oxides. Sulfur dioxide itself is a toxic gas that can cause serious damage to the human body. If these materials are not treated and directly emitted from the flue gas, it will inevitably cause serious harm to the people and the ecological environment. Therefore, the treatment of sulfur dioxide gas and nitrogen oxides contained in flue gas has become a problem that must be faced in China’s thermal power plants at present. Desulfurization and denitrification of flue gas generated by thermal power plants can effectively protect the ecology. The environment reduces pollution. With the rapid development of economic science and technology, people pay more and more attention to the protection of ecological environment. How to effectively treat flue gas desulfurization and denitrification in thermal power plants has become one of the most important research projects of many relevant staff in the industry. According to the relevant principles of the integrated treatment technology of flue gas desulfurization and denitrification in China’s thermal power plants at present, this paper compares some advantages of flue gas desulfurization and denitrification integration technology, and hopes to be engaged in thermal power plant flue gas. The relevant staff of the desulfurization and denitrification work will provide some help in the future work.
