The limestone-gypsum wet desulphurization process was originally adopted in a desulfurization system for sintering flue gas of Iron-making Plant of Baotou Steel and the raw material of desulfurizer was the finely ground limestone powder. In this industrial experiment, the desulfurizer of calcium hydroxide was as the research object and the experimental study on part or all of limestone was replaced by calcium hydroxide was carried out. The experimental results showed that the sulfur dioxide at outlet is discharged with standard level and the consumption of desulfurizer is reduced, but the pH value of seriflux in absorption tower fluctuates greatly with the desulfurizer of calcium hydroxide in the desulphurization system for flue gas of sintering machine, which has greater influences on its long-term stable operations.

包钢炼铁厂某烧结烟气脱硫系统原采用石灰石-石膏湿法脱硫工艺,脱硫剂原料为细磨石灰石粉。此次工业试验以氢氧化钙脱硫剂作为研究对象,进行了氢氧化钙部分替代以及全部替代石灰石的试验研究。结果表明,氢氧化钙脱硫剂用于烧结机烟气脱硫系统,出口二氧化硫达标排放,脱硫剂消耗降低,但吸收塔浆液pH值波动较大,对脱硫系统长期稳定运行影响较大。

包钢炼铁厂某烧结烟气脱硫系统原采用石灰石-石膏湿法脱硫工艺,脱硫剂原料为细磨石灰石粉。此次工业试验以氢氧化钙脱硫剂作为研究对象,进行了氢氧化钙部分替代以及全部替代石灰石的试验研究。结果表明,氢氧化钙脱硫剂用于烧结机烟气脱硫系统,出口二氧化硫达标排放,脱硫剂消耗降低,但吸收塔浆液pH值波动较大,对脱硫系统长期稳定运行影响较大。

The limestone-gypsum wet desulphurization process was originally adopted in a desulfurization system for sintering flue gas of Iron-making Plant of Baotou Steel and the raw material of desulfurizer was the finely ground limestone powder. In this industrial experiment, the desulfurizer of calcium hydroxide was as the research object and the experimental study on part or all of limestone was replaced by calcium hydroxide was carried out. The experimental results showed that the sulfur dioxide at outlet is discharged with standard level and the consumption of desulfurizer is reduced, but the pH value of seriflux in absorption tower fluctuates greatly with the desulfurizer of calcium hydroxide in the desulphurization system for flue gas of sintering machine, which has greater influences on its long-term stable operations.
