摘　　要：基于化学吸收法,首先深度分析了旋流流场及其对反应过程的强化原理,为旋流脱碳反应器传质特性提供理论依据。再通过分析三种脱碳强化方式对旋流器脱碳效率和气相总传质系数的影响,认为逆流和错流气液接触方式具有极大的技术经济性和工程化水平。此外,吸收剂的选择和操作条件的优化直接决定了旋流设备使用寿命、脱除效率及投资成本,因此高吸收速率、高吸收容量、低再生能耗的复合型吸收剂成为提高分离效率的重要研究方向。Based on the chemical absorption method, the vortex flow field and its strengthening principle for the reaction process were analyzed in this paper and a theoretical basis for the mass transfer characteristics of the cyclone decarbonization reactor was provided. By analyzing the effects of three decarburization strengthening methods on the decarburization efficiency of the cyclone and the total mass transfer coefficient of the gas phase, it was concluded that the countercurrent and crossflow gas-liquid contact modes have great technical and engineering levels. In addition, the choice of absorbent and the optimization of operating conditions directly determine the service life, removal efficiency and investment cost of the cyclone equipment. Therefore, the composite absorbent with high absorption rate, high absorption capacity and low regeneration energy consumption has become an important research direction to improve separation efficiency.
