摘要

针对已经设计完成的某大型多效蒸发海水淡化系统，分析了在分段等面积温差分配方案条件下，系统变工况运行中的某些热工水力学动态响应特性.研究结果给出了海水侧结垢厚度没有稳定之前，系统各效传热面积利用率以及产水潜力的变化情况；分析了原料海水温度因季节变化而降低，影响到系统正常运行时，应该在补给海水流量上采取的措施.还讨论了补给海水流量对核供热堆功率的跟随特性，给出了对应于反应堆不同功率应采用的最佳补给海水流量.本文报道的研究工作可为大型核供热堆多效蒸发海水淡化系统的安全经济运行提供理论依据.

Abstract

The dynamic response of a designed large capacity VTE-MED nuclear seawater desalination system

with temperature difference distribution scheme with in-section equal area of heat exchanger under unsteady state operating conditions

was explored based on the established mathematical model. The process of specific heat transfer areas increasing with scale deposit in tubes under high top boiling temperature (TBT) was illustrated. The decrease of GOR

and even the termination of normal operation of the system caused by temperature drop of feed brine because of seasonal variation was explored

and corresponding measure of adjusting feed brine flux was proposed. Under different source heat flux

optimal brine feed was selected to obtain the highest GOR. The present work would be helpful for efficient and safe operation of nuclear VTE-MED desalination plant.
