摘　　要：应用酸碱质子理论,根据质子平衡方程建立了氨法脱硫洗涤液相关离子浓度与pH的相关性模型,并对其影响因素进行了讨论。研究表明:脱硫洗涤液理论计算pH与实测的pH基本吻合。结合实验验证了影响洗涤液pH的硫元素存在形态与脱硫洗涤液pH之间的相图关系,并提出模型修正方法。模型可作为氨法脱硫洗涤液pH的合理计算方法。Through the proton theory,based on proton balance equation,the correlation model of the ammonia desulphurization detergent related ion concentration and pH was established,and the impact factors are discussed.Research showed that pH calculated from this theory fit for the actual measured pH.The phase diagram between sulfur elements effecting the pH of the ammonia desulphurization detergent and pH was obtained with the experimental study,and the modified methods were put forward.The model can be utilized as the reasonable calculation method of ammonia desulphurization detergent pH.
