摘要：

Experimental and analytical studies of CO2 absorption performance are carried out in a gas-liquid two-phase flow atomizer on the basis of a gas diffusion model. The gas-liquid two-phase flow atomizer with high spray efficiency and low power consumption has been applied to CO2 absorption. Experiments for the CO2 absorption were conducted in an isolated room and the results showed that, the mist sprayed by the improved atomizer can effectively reduce the CO2 concentration. Furthermore, a CO2 diffusion model was developed to predict the absorption process. This model was validated through a comparison between calculation and experiment. Comparison results showed that the proposed model could predict the time-variations of CO2 concentration well in the test room.
