In this work, the absorption performance of SO₂ into calcium-based solution was studied in a rotating packed bed (RPB). Experiments were carried out to examine the effect of various operating parameters on the desulfurization efficiency, such as absorbent pH value, gravity level of RPB, gas-liquid ratio, gas treatment amount and inlet SO₂ concentration. It was found that the SO₂ removal efficiency increased with the increasing of absorbent pH value and RPB gravity level, and decreased with the increasing of the gas-liquid ratio and inlet SO₂ concentration. SO₂ removal efficiency was about 88% for the metal packing and 82% for the plastic packing under the optimal operating conditions when the SO₂ inlet concentration was 900 mg/m³. Moreover, volumetric mass transfer coefficient (K_Ga) in RPB of this absorption process was calculated. It was found that K_Ga was 7.83–19.34 s⁻¹ in RPB, almost 1 order of magnitude higher than that in packed tower and impinging stream gas-liquid reactor.

在这项工作中，在旋转填充床（RPB）中研究了SO ₂在钙基溶液中的吸收性能。进行实验以检验各种操作参数对脱硫效率的影响，例如吸收剂的pH值，RPB的重力水平，气液比，气体处理量和入口SO ₂浓度。结果表明，随着吸收剂pH值和RPB比重的增加，SO _2的去除效率增加；随着气液比和进口SO ₂浓度的增加，SO _2的去除效率降低。在最佳操作条件下，当SO填充时，金属填充物的SO ₂去除效率约为88％，塑料填充物的SO ₂去除效率约为82％。₂入口浓度为900 mg / m ³。另外，算出该吸收工序的RPB中的体积传质系数（K _G a）。结果发现，RPB中的K _g a为7.83-19.34 s ^-1，比填料塔和撞击流气液反应器的K _G a高近1个数量级。
