以内径72 mm的玻璃吸收塔为主体,分别采用Mellapack-250X型金属孔板波纹规整填料以及Dg16塑料阶梯环散堆填料作为传质媒介。以水-SO2作为研究体系,结合气液逆流接触吸收试验对比分析气液并流接触时填料层压降的情况,并分别考察了气相动能因子F和液气比L/V对填料吸收塔气液并流接触时填料层压降的影响。填料层压降随着气相动能因子F的增大呈指数型增长,随着液气比的增加而升高,并流操作时的影响相对逆流操作时变化幅度较小。通过试验结果拟合出相应压降的关联式,为进一步的工艺设计与优化提供相关依据与理论指导。
The inner diameter of 72 mm glass absorber as the main body, respectively, using Mellapack-250X corrugated metal plate corrugated structured packing and Dg16 plastic ladder loop packing as a mass transfer media. Taking water-SO2 as the researching system, the gas-liquid countercurrent contact absorption test was used to compare the pressure drop of the packed bed during the gas-liquid co-current contact. The effect of gas phase kinetic energy factor F and liquid gas ratio L / V on the packing absorber gas Effect of pressure drop on the packing layer when liquid is in cocurrent contact. The packing pressure drop increases exponentially with the increase of kinetic energy factor F of the gas phase, and increases with the increase of the liquid-gas ratio. The effect of the cocurrent operation is smaller when compared with the countercurrent operation. The correlation of pressure drop is fitted out through the test results to provide relevant basis and theoretical guidance for further process design and optimization.
