摘要
以吸收瓶为实验装置研究了几种碱性废渣的脱硫容量。实验结果表明 ,电石渣、碱渣、废大理石和石灰石的脱硫容量分别为 0 85、0 75 ,0 6 2和 0 5 8gSO2 g脱硫剂。旋流板塔试验主要参数对脱硫率的影响结果表明 ,入塔浆液pH值越大 ,液气比L G越大 ,脱硫率η也越高 ;入塔SO2 浓度y0 越高 ,脱硫率η越低。模拟工业试验结果表明 ,对电石渣和碱渣 ,控制浆液pH >7,L G =2～ 3L m3时 ,η可达 6 5 %以上 ;对废大理石和石灰石 ,控制浆液pH为 6 5 ,L G =4～6L m3时 ,η可达 6 0 %以上。从以上结果来看 ,作为脱硫剂 ,电石渣脱硫效果最好 ,碱渣次之 ,最后是废大理石和石灰石。
The desulfurization capacity of several alkaline waste slags was studied in absorber bottle.The results showed that the desulfurization capability of carbide slag,alkaline slag,waste marble and limestone was 0.85,0.75,0.62 and 0.58 g SO 2/g desulphurizer respectively.Main parameters affecting SO 2 removal efficiency in a rotating stream tray using the alkaline waste slags showed that SO 2 removal efficiency increases with inlet slurry pH value and liquid/gas ratio and decreases with inlet SO 2 concentration.The SO 2 removal efficiency can reach more than 65% when pH>7 and L/G=2～3 L/m 3 for carbide slag and alkaline slag,and more than 60% when pH=6.5 and L/G=4～6 L/m 3 for waste marble and limestonc.From the results,the order of good desulphurizer was carbide slag,alkaline slag,limestone and waste marble.Carbide slag and alkaline slag have a better application potential.
