摘要:

为提高吸附捕获烟气CO₂的吸脱附率,在分析了吸脱附各影响因素和吸脱附过程热效应的基础上,设计并提出在吸附器外设置套管的套管式吸附器,建立套管式吸附器的数学模型并进行求解,模拟计算了套管内通入不同温度水时,吸附器的吸附量和脱附率.研究结果表明,本文提出的套管式吸附器能够强化吸附捕获烟气中的CO₂.

Abstract:

Tube-in-tube type adsorber was designed and proposed based on analyzing various influencing factors as well as heat effect in the process of adsorption and desorption. And then its mathematical model was established and solved. Finally, the adsorbing capacity and desorption rate of adsorber were simulated at the condition of different temperatures of water bubbled into it. Results showed that tube-in-tube type adsorber could enhance carbon dioxide adsorption and capture from flue gas, which are helpful for potential engineering application.
