冶金粉尘硫容量的实验研究

Study on the sulfur capacit of metallurgical dusts

在25-650温度范围内测定了由Fe 、Ca、 Zn 、Mn等氧化物组成的高炉冶金粉尘脱除H_2S的硫容量，结果表明，反应温度驵成对高炉冶金粉尘硫容量有较大影响，在25-650范围内，硫容量增加：当温度低于350时，CA,Zn,Mn氧化物对冶金粉尘硫容量起主要作用 ，且碳的存在于提高治金粉尘对H_2S的吸附能力，可适度提高冶金粉尘硫容量；温度大于350时，氧化物对冶金粉尘硫容是起主要作用，碳含量对冶金粉尘硫容量的影响较小，高炉 冶金粉尘脱流主要受Fe氧化物脱硫反应及H_2S氧化物脱硫反应及H_2S在冶金粉中的扩散影响，

Sulfur capacity of metallurgical dusts was meaeured im temperature from 25.tp 650.The experimental ueaults show that sulrur capacity of metallurgical affected ocides of zinc,calcium and mangaoese when temperature is less tham350.Its desulfurization ability is decided by iron oxides when temperaturs is higher than350.Carbon content has apositive effect on letallurgical dusts desulfuriaztion ability when telperature iv less than 350.this effect may be invalid then temperature is greater than350 as desulfurization is decided by chemical reaction and H_2Sdiffusion metallurgical dusts under this condition ,
