摘　　要：介绍了脱硫新工艺除脱硫外还能进行脱碳。这个工艺包含SO2氧化、吸收、中和、结晶等工序及CO2的吸收、碳化过程,所有工序均在碳化窑中进行。此脱硫新工艺的原料来源非常的广泛,使用工业废料电石渣代替石灰石作为SO2和CO2的吸收剂。工艺的脱硫效率和脱碳效率均能达到99%,将脱硫和制砖结为一体,具有极高的应用价值和环境效益。A new process of flue gas desulfurizafion is introduced, and its mechanism of desulfurization and decarburization, and SO2 removal efficiency are presented. Some points of this process and the environment benefits are also summarized. All reactions, including oxidation, absorption of SO2, gypsum crystallization and carbonization, absorption of CO2, are completed in the brick kiln. Finally, both desulfurization and decarburization efficiency are as high as 99%. In comparison with other methods of desulfurization, this process combines desulfurization and carbon brick making, which can bring in highly commercial value.
