| 摘 要： | 引 言迄今为止 ,旋转填充床 (ＲａｔａｔｉｎｇＰａｃｋｅｄＢｅｄ ,ＲＰＢ)用于模拟烟气的脱硫吸收 (包括物理吸收和化学吸收 )已经有了较多的研究 ,ＲＰＢ中ＳＯ2 物理吸收的传质模型已有报道[1～ 3] ,但有关化学吸收的数学模型还属鲜见 .在数学上描述ＲＰＢ中ＳＯ2 化学吸收的传质 -反应特征 ,必须考虑物质传递和化学反应两个方面的影响因素以及这两种因素间的相互关系 .描述气 -液相之间的物质传递过程有不同的传质模型[4 ,5] ,如双膜理论、Ｈｉｇｂｉｅ渗透理论、Ｄａｎｃｋｗｅｒｔｓ表面更新理论和湍流传质理论等 ,但用之于处理具体…

| Abstract: | In this paper the rotating packed bed, a new type of absorber, which has high mass-transfer characteristic by means of centrifugal field instead of gravity field, is used to study on stimulated flue gas desulfurization. Based on experimental data,a model of mass-transfer and reaction of the sulfur dioxide chemical absorption in the rotating packed bed reactor is proposed according to the film-theory. It can be used to predict the performance of the total absorption rate and the enhancement factor of the sulfur dioxide and oxygen simultaneous absorption in the rotating packed bed reactor.The prediction of the model is consistent with the experimental result varying operating conditions, and the relative error between experimental result and predicted result is below 12%. Some interesting potential projects of simultaneous absorption of sulfur dioxide and oxygen in the rotating packed bed reactor are also discussed. |
