摘　　要：从理论和实验两方面研究了支撑熔盐膜法烟气脱硫新技术。采用非平衡态热力学建立了ＳＯ_２传质的数学模型，并用电子计算机进行求解；考察了电流密度、气相中ＳＯ_２浓度、阴极室气体流量等因素对ＳＯ_２传质的影响。实验结果与理论解相符合。The sulfur dioxide removal from flue gas was investigated using a supported molten salt membrane.The mathematical model of SO2 transfer in the membrane was established with the use of non-equilibrium thermodynamics theory and calculated on an electronic computer.The experimental quantities,such as the electric current density,the concentration of SO2 and the gas flow rate in cathode compartment were tested.The experimental results were in good agree ment with the model.
