| 摘 要： | 以逆流旋转填料床为脱硫设备，络合铁为脱硫剂，对模拟气中的H2S进行了脱硫实验研究。考察了气/液流量比、超重力因子、气体流量、H2S入口质量浓度对脱硫率的影响，并对比分析了逆流旋转填料床与错流旋转填料床的脱硫性能。结果表明，相比错流旋转填料床，逆流旋转填料床更适合于低硫尾气的精脱硫，脱硫率可达99%以上。与传统塔式脱硫技术相比，逆流旋转填料床络合铁法脱硫技术脱硫效率高、气/液流量比大、设备体积小，具有工业化应用潜力。

| Abstract: | H2S removal from analog gas by chelated iron was investigated in a counter-current rotating packed bed. The influences of gas-liquid flow ratio, high gravity factor, gas flow rate and mass concentration of H2S in feed gas on H2S removal efficiency were studied. The desulfurization properties of counter-current rotating packed bed and cross-flow rotating packed bed were analysed comparatively. It was illustrated that counter-current rotating packed bed with the H2S removal efficiency of more than 99% was more suitable to fine desulfurization for low-concentration H2S compared with cross-flow rotating packed bed. Compared with the traditional tower equipment for desulfurization, counter-current rotating packed bed desulfurization method showed a potential industrial application due to its great advantages of higher desulfurization efficiency and gas-liquid flow ratio, smaller volume, etc. |
