摘　　要：采用全新工艺流程,设计了一种新型双效气液并流吸收塔,塔内安装有改进型立体旋液式塔板。分别以空气、空气-水作为研究体系进行实验,考察了不同操作参数与塔板结构参数下双效气液并流吸收塔的干塔压降、湿塔压降以及立体旋液式塔板的干板压降、湿板压降,明确了双效气液并流吸收塔的操作参数范围。实验结果表明:立体旋液式塔板单板干板压降及湿板压降分别控制在70 Pa,180 Pa以内。在一效、二效各逆向安装3块塔板,全塔共完全安装6块塔板时,全塔压降最大,但是干塔压降及湿塔压降可分别控制在2 400 Pa,2 800 Pa以内,双效气液并流吸收塔与立体旋液式式塔板的组合在能耗及操作弹性方面优势明显。By means of a novel process,a new type of double-effect gas-liquid cocurrent flow absorption column was designed,inside which an improved stereoscopic and swirl tray was installed. Using air and air-water as experimental research systems,respectively,the dry and wet pressure drops of the new absorption column and the stereoscopic and swirl tray were examined under different operating parameters and tray structural parameters,determining the operating parameters for this new absorption column. Experimental results show that dry and wet pressure drops of a single stereoscopic and swirl tray are controlled at 70 Pa and 180 Pa respectively. The largest whole column pressure drop is achieved when three trays are reversely installed at the first and second effects respectively,i. e. in total,six trays are installed in the column,whereas the dry and wet pressure drops of the column are controlled within 2 400 Pa and 2 800 Pa respectively. This combination of the new absorption column and the improved tray gives significant advantages in operating flexibility and energy consumption.
