一、高炉大型化与烟尘治理近代化的高炉生产迄今已有一个多世纪了,但高炉出铁场的烟尘污染一直未引起重视,自进入六十年代国际性的消除“公害”运动蓬勃发展后,高炉出铁场的烟尘治理才被提到日程表上来。然而治理进展极不平衡而且缓慢,至七十年代初,工业发达国家的高炉向大型化发展,随之其孪生的出铁场烟尘污染更显突出,成为急待解决的新课题。当前,环境保护排放标准日益严格,出铁场的烟尘治理设施已成为高炉生产必不可少的设施。这是因为: First, large-scale blast furnace and dust control Modern blast furnace production so far for more than a century, but the blast furnace slag smoke pollution has been paid no attention, since the sixties into the international elimination of “public nuisance” movement booming , Blast furnace tundra dust control was mentioned on the calendar. However, the progress of governance was extremely unbalanced and slow. By the early 1970s, the blast furnace industry in developed industrialized countries was becoming more and more large-scale, and the dust pollution from its twinning ironworks became even more prominent. This has become a new issue that needs urgent solution. At present, the emission standards for environmental protection are becoming increasingly stringent. The facilities for dust control at the ironworks have become an indispensable facility for blast furnace production. This is because:
