摘　　要：基于以废治污、保护环境的目的,选取了7种含碱固体废弃物作为流化床燃煤脱硫剂,利用热重分析技术对含碱工业废弃物及其复合脱硫剂的硫化反应特性进行了实验研究。结果表明,碱渣、盐泥、赤泥在850℃左右具有较好的脱硫特性;白泥和电石渣,最佳脱硫反应温度介于900℃～1 000℃之间,具有较好的高温脱硫性能;白泥、电石渣和石灰石中加入赤泥添加剂后,虽然脱硫效率有不同程度的提高,但最佳脱硫温度下降;白泥、电石渣与碱渣、盐泥复合后,烧结加重,有效离子利用率降低。Based on the purpose of waste governance pollution and protecting environment,desulfuration performance of alkaline industry wastes and Composite desulfurization agents were studied by thermo-gravimetric analysis technology.It can be found that alkali slag,red mud and salt slurry have better desulfurization performance at 850 ℃,white clay and carbide sludge,whose best desulfurization reaction temperature ranged from 900 ℃ to 1 000 ℃,have good high-temperature desulfurization performance.Desulfurization performance of limestone,white clay and carbide sludge are improved when added into red mud,but their best desulfurization reaction temperature drop.Alkaline slurry and salt slurry exacerbated sinter of white clay and carbide slag,which make desulfurization result of white clay and carbide slag reducted.
