不锈钢除尘灰煤基氢冶金资源化工业实验研究
Industrial Test Research on Stainless Steel Dust with Coal-based Hydrogen Metallurgy for Recycling Purpose
摘要
Abstract
The self-developed coal-based hydrogen metallurgical technology and coal-based hydrogen metallurgical rotary kiln industrial test device were used to carry out the industrial test on stainless steel dust with coal-based hydrogen metallurgy in the rotary kiln for harmless and recycling purpose.The metallization ratio of nickel,iron,and chromium are 100%,91.24%and 86.18%,respectively,at the conditions of hydrogen metallurgical reduction temperature of 1 250℃and the time in the kiln of about 3 h,and all the produced materials of which the indexes are lower than the standard limit of extraction toxicity identification.Thermodynamic analysis was carried out for coal-based hydrogen metallurgy process on stainless steel dust.It forms a harmless and recycling process package for stainless steel dust,including coal-based hydrogen metallurgical rotary kiln which is the core technology,dry cooling,dry magnetic separation,gravity jig separation and other main processes.关键词
