氧化铁浆液脱硫的实验研究与理论分析

THE EXPERIMENTAL STUDY AND THEORETICAL ANALYSIS ON THE DESULFURATION OF Fe_(2)O_(3)-WATER SLURRY

本文实验研究了氧化铁浆液在酸性环境下脱除烟气中的二氧化硫气体。实验在一自制的脱硫塔中进行。通过燃烧液化石油气来产生烟气,将氧化铁的超细粉加入水中作为脱硫介质。实验中研究了二氧化硫初始浓度、水气比对脱硫效率的影响。从实验结果可以看出,脱硫率随着水气比的增加而增大;随二氧化硫的初始浓度的增加,其脱硫率呈降低趋势。在文中同时分析了氧化铁浆液的脱硫机理和此方法脱硫的优点以及目前存在的问题。

The desulfuration characteristics of the Fe2O3-Water Slurry in the acid ambient were investigated in the paper. The experiments were carried out in a self-made tower. The flue gas was got by the combustion of the LPG. The super-micro powder of the Fe2O3 in the water acts as the absorbent. The effect of the initial concentration of SO2 and the ratio of water and flue gas was studied with the experiments. The experimental results show that the desulfuration efficiency increases with the increase of the ratio of water and flue gas and decreases with the initial concentration of SO2. The desulfuration mechanics of the Fe2O3-Water Slurry and the advantages and shortcoming of this method are analyzed in this paper, too.
