中文摘要：

在由使用包含液体的膜的模仿的烟道气体的硫二氧化物的吸收被调查。从柠檬酸盐答案的吸收剂的硫二氧化物解吸附作用的过程被探索。影响煤气阶段，并且硫二氧化物的吸收效率和硫二氧化物的解吸附作用效率上的超声的频率，超声的力量和激动人心的速度的影响上的液体阶段被检验。结果显示吸收效率与增加流动速度和硫二氧化物内容在减少煤气阶段，并且能被增加集中和柠檬酸盐答案的 pH 值改进。在更好的排除效率降低超声的频率结果，这被结束。在使放出使用超声从柠檬酸盐答案的硫二氧化物在一些改进使放出的效率调节，没有改变化学反应的本质。

英文摘要：

The absorption of sulfur dioxide in simulated flue gas by using liquid-containing membrane was investigated.The process of sulfur dioxide desorption from the absorbent of citrate solution was explored.The influence of the gas-phase,and the liquid-phase on absorption efficiency of sulfur dioxide and the influence of ultrasonic frequency,ultrasonic power and stirring speed on desorption efficiency of sulfur dioxide were examined.The results indicate that the absorption efficiency decreases with increasing flow velocity and sulfur dioxide content in gas-phase,and can be improved by increasing the concentration and the pH value of citrate solution.It is concluded that lower ultrasonic frequency results in a better degassing efficiency.The using of ultrasound in desorbing sulfur dioxide from citrate solution improves the desorbing efficiency in the some conditions,without changing the essence of chemical reaction.
