建立了错流中空纤维膜液体除湿组件的二维传热、传质数学模型,引入研究传质过程质量积耗散的湿阻来衡量溶液除湿过程中水分传递的不可逆性。通过分析膜法除湿组件中除湿与传热耦合的湿空气水分传递过程,得到了热湿传递过程中传质的阻力表达式。通过一个典型设计实例,得出了可以降低中空纤维膜除湿组件不可逆传质损失的管长、根数、管间距、排列方式等设计参数。 A two-dimensional mathematical model of heat transfer and mass transfer of cross-flow hollow fiber membrane dehumidification module was established. The wet resistance of mass transfer dissipation was introduced to measure the irreversibility of moisture transfer in solution dehumidification process. By analyzing the moisture transfer process of moisture in the dehumidification module coupled with dehumidification and heat transfer, the resistance expression of mass transfer in the process of heat and moisture transfer was obtained. Through a typical design example, the design parameters such as tube length, root number, tube spacing and arrangement method, which can reduce the irreversible mass loss of the hollow fiber membrane dehumidification module, are obtained.
