摘　　要：介绍了钠碱法烟气脱硫技术中副产物资源化利用情况。通过对钠碱法脱硫反应副产物的特性、应用前景及生产技术的研究,提出可行性的资源化利用方法。依托现有的150 kt/a亚硫酸钠生产系统,根据市场需求选择相应工艺生产亚硫酸氢钠、焦亚硫酸钠、硫代硫酸钠等亚硫酸盐类产品,既可实现冶炼烟气的高效治理,又可避免亚硫酸钠、硫酸单一产品的滞销,产品多样化,提高系统的整体经济性。Resource utilization of flue gas desulphurization by-product by natrium-alkali method is introduced. By research of characteristics,application prospect and production technology of reaction by-products,resource utilization methods are proposed. De-pending on existing 150 kt/a sodium sulphite production system, corresponding technolog were selected to produce sulphites productsof sodium hydrogen sulphite,sodium pyrosulphite and hyposulphite according to market requirements,not only realizing efficient man-agement of flue gas, but also avoiding unsalable of single product of sodium hydrogen sulphite and sulphuric acid, rproducts and improving overall economy.
