摘　　要：莱钢4#265m2烧结机烧结烟气脱硫系统采用有机胺吸附解吸工艺,系统由烟气净化及SO2吸收、吸附液再生、胺吸附液过滤净化等工序组成,通过从环冷机引出废热,经再沸器后排放,解决了烟气温度低且波动大的问题;增加除氯站,除去吸收剂中富集的氯离子;采用自清洗空气过滤器等保证产品酸的品质。改进后系统运行稳定,烟气入口SO2含量<1300mg/m3,出口SO2含量<100mg/m3,脱硫率>92%。The desulphurization of sintering flue-gas from No.4 265 m^2 sintering machine in Laiwu Steel adopted organic amine adsorption and desorption process. The system consisted of fume gas cleaning, SO, absorbing, adsorption solution reclaiming and the filtration and cleaning of amine adsorption solution etc. The waste heat from cooling machine discharged through the reboiler, resolving the problems of low flue-gas temperature and fluctuation. Adding Cl exenterated equipment removed enriehed chloride ions in the absorber. Air filter ensured H2SO4 quality. After improvement, the system run steadily, the SOs content of flue-gas at entry and exit were less than 1 300 mg/m^3 and 100 mg/m^3 and the rate of desulphurization was more than 92%.
