背景技术 Background technique
传统吸收塔多采用气液逆流的传质方式，这种传质方式为了达到吸收的目的，需要根据烟气浓度、吸收效果设计塔高、塔径。虽然传质效果好，但是大规模的吸收过程需要很高的设备塔高与宽的设备塔径才能达到吸收要求，因此设备的工程量很大，建造、改造与拆卸都会耗费大量物力财力。 Traditional absorption towers mostly adopt the mass transfer method of gas-liquid countercurrent. In order to achieve the purpose of absorption in this mass transfer method, the tower height and tower diameter need to be designed according to the flue gas concentration and absorption effect. Although the mass transfer effect is good, the large-scale absorption process requires a high equipment tower height and a wide equipment tower diameter to meet the absorption requirements. Therefore, the equipment requires a large amount of engineering, and construction, transformation and dismantling will consume a lot of material and financial resources.
传统吸收塔受困于为满足吸收效果需要进行大工程量的设备建造，塔高与塔径的设计都有很高要求；同时传统吸收塔只能针对相对固定流量的气体进行设计，如果实际运行过程中流体流量无法达到设计要求或者超出设计要求都会影响吸收效率，且不易做出设备上的调整。 The traditional absorption tower is trapped in the construction of a large amount of equipment to meet the absorption effect, and the design of the tower height and tower diameter has high requirements; at the same time, the traditional absorption tower can only be designed for a relatively fixed flow rate of gas. If the actual operation The fluid flow rate in the process cannot meet the design requirements or exceed the design requirements will affect the absorption efficiency, and it is not easy to make adjustments on the equipment.
