以双搅拌釜为实验设备，研究了烟气脱硫过程中硫酸钠、硫酸镁和腐殖酸钠对石灰石的促溶作用。结果表明，分别采用3种不同添加剂时，ph值等随脱硫反应时间的变化规律类似；与非强化石灰石脱硫过程对比，在相同ph值下，3种添加剂均使石灰石颗粒体积占初始体积的分率rp减小，即均能促进石灰石的溶解，改善浆液的传质性能。通过理论分析，导出了rp与浆液ph值之间的关系式，该方程能很好地关联双搅拌釜实验数据。

向石灰石脱硫浆液中添加硫酸钠可提高脱硫率。以旋流板塔为吸收器,测定了钠强化石灰石湿式烟气脱硫过程的脱硫率、ph值等随脱硫反应时间的变化情况，对不同ph值范围内的石灰石溶解速率等进行了分析。在与工业操作温度相近的条件下,测定了不同塔板数时的脱硫率和塔压降,计算了平均单板效率。结果表明，增加塔板数，脱硫率提高,而平均单板效率减小，实验条件下，塔板数由1增加到4，液气比为4l/m3时脱硫率由25.5%提高到48.6%,而平均单板效率则由25.5%下降到15.3 % 。得出了平均单板效率与塔板数之间的关系式。

the flow field of gas and liquid in a ф150mm rotating-stream-tray (rst) scrubber is simulated by using computational fluid dynamic (cfd) method. the simulation is based on the two-equation rng k-ε turbulence model, eulerian multiphase model, and a real-shape 3d model with a huge number of meshes. the simulation results include detailed information about velocity, pressure, volume fraction and so on. some features of the flow field are obtained: liquid is atomized in a thin annular zone; a high velocity air zone prevents water drops at the bottom from flying towards the wall; the pressure varies sharply at the end of blades and so on. the results will be helpful for structure optimization and engineering design.
