摘要
中国能源以煤炭为主,煤炭燃烧产生的烟气中含有大量的SO2,对大气环境造成严重污染,并在我国局部地区形成酸雨,严重危害生态环境及人民健康。文章通过对常用湿式脱硫工艺的研究比较,肯定了钠-钙双碱法烟气脱硫工艺的优越性。详细介绍了钠-钙双碱法烟气脱硫系统的脱硫原理、工艺特点以及与传统湿法脱硫工艺相比的优点。同时指出了双碱法脱硫工艺需解决的问题。
China's coal-based energy sources, coal combustion process produces flue gas what contains large amounts of coal combustion, cause serious pollution to the atmospheric environment, and the formation of acid rain in some areas in China, seriously endangering the ecological environment and people's health. In the paper, by comparison used wet desulfurization process, substantiate the Na-Ca double process flue gas desulphurization technology was superior. And introduced the desulfurizing mechanism,technological features and desulfurizing effect of Na-Ca double base process. Also pointed out that the problems need to be addressed of the Na-Ca double process flue gas desulphurization technology.
