Enhancement of Absorption of Injected Gas in New Type Mechanical Stirring Injection Refine Equipment
The bubble disintegration is of great scientific importance in metal refining, In order for further improvement, Research on bubble disintegration and dispersion becomes necessary, The intensification of bubble disintegration experiment that we have done in cold water model by study absorption rate ,The purpose is to research bubble disintegration under difference experimental condition . In this paper, we use mass transfer coefficients stand for absorption rate, we also study utilization rate, we want to research the best experimental condition which can enhance mass transfer coefficients and utilization rate. On the basis of experimental result, Provided a scientific and experimental basis to high-temperature experiment of bubble dispersion and disintegration .Experimental results show:the rate of absorption of CO2 injected in aqueous NaOH solution can be increased greatly by mechanical stirring when the positive-reverse rotation mode is adopted. Dispersion of small bubbles in the liquid is very effective for increasing the absorption rate.
