摘要：

The mechanism and process of sintering flue gas desulfurization by steel slag were investigated in bubbling tower made up organic glass with a diameter of 80mm and a height of 300mm, which is a kind of simplified good gas-liquid mass transfer equipment. The effects of various operating parameters, i. e., steel slag particle size, slurry concentration, import sulfur dioxide concentration, pH value and flue gas flow were systematically investigated in the experiments. The most optimal experimental conditions for sintering flue gas desulfurization was found that when the temperature is normal temperature, steel slag particle size is greater than 200 mesh size, slurry concentration is greater than 4%, imports SO2 concentration is less than 2 000mg/m3, flue gas flow is less than 0.06m3/h, initial pH value is more than 7, the SO2 removal efficiency could achieve 80% above. The mechanism of sintering flue gas desulfurization by steel slag was explored by comparative analysis of XRD and XRF date of steel slag before and after desulfurization. Steel slag as desulfurization agent and treating wastes with wastes can be achieved, the industrial waste can be changed in to resource and the costs can be reduced. © 2017, The Editorial Board of Journal of Basic Science and Engineering.
