摘要

结合Danckwerts的界面更新模型

初步分析了纳米颗粒强化氨水鼓泡吸收过程的机理.改变不同的氨气流量和基液氨水浓度

进行了Al_2O_3纳米颗粒对氨水鼓泡吸收性能的强化实验.实验表明:Al_2O_3纳米颗粒对氨水鼓泡吸收性能具有强化效果:在实验条件下

加纳米颗粒的吸收效果最大可以达到没有加纳米颗粒的1.22倍;在保持其它条件一定时

随着氨气流量增加

溶液吸收率增加

但有效吸收率出现有增大也有减小的不规律特征

而随着基液氨水浓度的增加

有效吸收率增加比较明显.为研制小型氨水吸收式制冷机的鼓泡式吸收器提供参考.

Abstract

From the Danckwerts theoretical surface renewal model of mass transfer

an approach using nanoparticles to enhance ammonia bubble absorption process was examined in this study.In our experiment

the ammonia vapor flow flux and the concentration ratio of bulk ammonia solution were adjusted and their effects on ammonia bubble absorption were explored.The experimental results show that the absorption ratio was significantly increased by adding Al2O3 nanoparticles in the bulk solution

and the effective absorption...
