攀枝花硫-钛-钢联产可行性分析

Analysis on the Feasibility of Co-production of Sulfuric Acid, Titanium Pigment and Iron and Steel in Panzhihua

以攀枝花现有的钢铁和钛白两大产业为基础,以副废资源化利用为目标,提出了"硫-钛-钢"联产的思路,并依次分析了脱硫酸、高炉渣、炼钢炼铁余热、稀钛液、绿矾、红渣等副废在钢铁系统和硫酸法钛白产业中资源化利用的可行性。得出"硫-钛-钢"联产是攀枝花实现铁、硫、钛资源高效利用和清洁生产的较佳生产模式,可以在国内形成绿色产业示范基地。

Aiming at utilizing wastes and by-products, the conception of ＇ co-production of sulfuric acid, titanium pigment and iron and steel＇ is put forward based on the existing iron ＆ steel and titanium pigment industries in Panzhihua, and the feasibility of reutilizing by-products and wastes generated in the two production processes including waste acid, blast furnace slag, ironmaking and steelmaking afterheat, dilute titaniferous solution, copperas, and red slag is analyzed. It can be concluded that the co-production of sulfuric acid, titanium pigment and iron and steel is a good way to realize efficient utilization and clean production of iron, sulfur and titanium resources. It is suggested that a green industry demonstration base be established in Panzhihua.
