An experimental apparatus of falling film absorption in a vacillating is set up to check the reliability of theoretical model and to have a deep understanding of heat and transfer of practical falling film absorption ; falling film absorption with tfe / nmp solution in a static vertical tube and that in a vacillating tube are investigated respectively 为验证理论模型的可靠性并进一步深入了解实际摇摆降膜吸收过程中热、质传递规律,自建了摇摆振动单管吸收试验台;分别对静止和摇摆状态下tfe / nmp垂直管内降膜吸收进行实验研究。
