摘要
介绍了我国目前大气氟污染的现状及治理措施。针对煤烟型氟污染问题 ,在总结已有治理方法的基础上 ,进行了在煤燃烧过程中添加除氟剂的干法除氟技术试验。试验结果表明 ,已开发的几种除氟剂可达到 4 5 %～ 75 %的除氟率。同时 ,除氟剂还具有一定的脱硫作用 ,脱硫率最高可达 70 %。
Status quo of fluorine pollution in atmosphere, as well as it’s prevention and control measures taken in China at present have been described. Directing against the problem of smoke form fluorine pollution, a dry method for fluorine-eliminating technology during combustion of coal has been put forward on the basis of summarizing methods taken at present. The said method adds fluorine-absorbing agents in the combustion process of coal. Results of test show that the fluorine-eliminating efficency of several developed fluorine-absorbing agents to be about 45～75%. In addition, the said agents have also the function of desulfurization, the max. efficiency of desulfuration being about 70%.
