摘要
喷雾法是一种高效的气液传质技术,在化学吸收法捕集CO_(2)领域引起了广泛关注。系统回顾了影响喷雾塔气液流动过程中的因素,讨论了喷雾的形成与分布机制,总结了气液流量、气液流向等操作条件对塔内气液流动特性和传质效率的影响,并对比了提高CO_(2)捕集性能的不同喷雾方案,还讨论了数值模拟方法以预测喷雾塔的吸收性能。未来,需要对喷雾塔的设计与优化方案进行深入研究,以推动高效、低能耗的CO_(2)喷雾捕集系统的开发与应用。
The spray method is an efficient gas-liquid mass transfer technology that has attracted widespread attention in the field of CO_(2) capture via chemical absorption.This paper systematically reviews the factors influencing the gas-liquid flow process in spray columns and discusses the formation and distribution mechanisms of the spray.The effects of gas flow rate,gas-liquid flow direction,and other operational conditions on the gas-liquid flow characteristics and mass transfer efficiency within the tower are summarized.Different spray configurations that enhance CO_(2) capture performance are compared.Additionally,this paper discusses numerical modeling methods to predict the absorption performance of spray towers.In the future,further research on the design and optimization of spray towers is required to advance the development and application of efficient,low-energy CO_(2) spray capture systems.
