中文摘要:
      针对用于海水淡化和高盐废水处理的机械蒸汽压缩(mechanical vapor compression,MVC)蒸发装置,基于系统和设备的质量平衡、组分平衡、能量平衡和系统自平衡循环的约束条件,建立了计算顺流、并流和逆流三种基本进料流程的MVC蒸发系统自平衡循环运行状态下的热力性能和换热通用模型。计算结果与实际工程测量结果比较显示,模型计算结果可以准确地模拟实际系统的运行结果。给出的模型可用于各种MVC蒸发系统热力过程的分析和设计。
英文摘要:
      Based on the mass, component and energy conservation of the system and equipment, and the constraint conditions of the system self-balance cycle, a general model for calculating the thermodynamic performance and heat exchange of the MVC evaporation system on self-balance cycle operation with three basic feeding patterns of forward flow, parallel flow and counter flow is established. The comparison between the calculation results and the actual engineering measurement results shows that the calculation results of the model can accurately simulate the operation state of the actual system. The model can be used to analyze the thermodynamic process of MVC evaporation systems and design the system and equipment.
