【摘要】 利用高温管式炉和烟气分析仪对4种工业碱基废弃物和1种石灰石固硫过程进行了试验研究,并利用压汞仪和X-射线衍射仪对废弃物的孔结构和固硫产物进行了研究。结果表明:白泥和电石渣在800~1100℃时对低温硫和高温硫都具有较强捕获能力,固硫性能较好;盐泥和赤泥在800~900℃时能够有效的捕获低温硫,固硫性能较好,当温度升至1000℃后其固硫性能变差。废弃物具有良好的微观结构,有利于颗粒内部固硫反应的进行。综合上述,工业碱基废弃物具有良好的固硫性能。更多还原

【Abstract】 The desulphurization characteristics of industry alkaline wastes and limestone were studied by means of flue gas analyzer and the high temperature tube reactor.Pore structure and desulphurization product characteristic were investigated respectively by mercury porosimeter and X-ray diffractometer.The result shows that white clay and carbide slag could effectual capture the release of sulfur at 800～1100℃.Salt slurry and red mud could effectual capture the release of sulfur at first stage at 800～900 ℃.But when the experimental temperature rise to 1 000 ℃,the sulfur capture abilities of them depress.Wastes represent good pore structure characteristics.This makes the sulfation reaction goes further.To sum up,wastes have good sulfur capture ability.更多还原
