研究了在超声波作用下柠檬酸钠溶液的性质对SO2解吸率的影响,探讨了超声场下柠檬酸盐溶液中SO2的解吸机理。结果表明:(1)在柠檬酸钠浓度较低,或者柠檬酸钠溶液初始pH值较低的条件下均能产生较好的解吸效果;(2)少量惰性气体的通入或者表面活性剂的加入能够降低溶液黏度,产生空化效应,从而提高了SO2的解吸率;(3)通过对比实验证明解吸结果与理论分析相吻合,其研究结果为SO2的深度解吸提供了技术思路,也为该项技术的工业放大提供了一定的基础数据.
The effect of the nature of sodium citrate solution on the desorption rate of SO2 under ultrasonic wave was studied. The desorption mechanism of SO2 in citrate solution under ultrasonic field was discussed. The results showed that: (1) better desorption effect was obtained under the condition of low concentration of sodium citrate or low initial pH value of sodium citrate solution; (2) introduction of a small amount of inert gas or surfactant Addition can reduce the viscosity of the solution, resulting in cavitation effect, thereby increasing the desorption rate of SO2; (3) By comparing the experimental results show that the desorption consistent with the theoretical analysis, the results of the study for the depth of desorption of SO2 provides technical ideas, but also for the The technical amplification of the project provides some basic data.
