【摘要】 针对错流塔盘板上存在液位梯度、造成大型塔器气液分布不均的现象,提出了一种穿流全喷射塔板（TST）,并以空气-水和空气-CO₂-水体系为操作介质,对其水力学和传质性能进行了实验研究。实验结果表明,与其他喷射塔板相比,TST具有压降小,漏液和雾沫夹带少的特点。在高板孔动能因子区,TST获得了比New VST更高的传质效率。更多还原

【Abstract】 In order to solve the problem of uneven gas-liquid distribution in large-scale towers caused by the presence of liquid-level gradients on cross-flow tray,a total spray tray（TST） is proposed.Its hydraulic and mass transfer performances are studied experimentally by using air-water and air-CO₂-water systems as operating media. The experimental results show that compared with other spray trays,TST has the characteristics of low pressure drop,low leakage and entrainment.In addition,TST achieves higher mass transfer efficiency in the high kinetic energy factor than New VST.更多还原
