海水淡化技术已成为解决淡水资源紧缺的有效途径之一。将贯通型(OTMSF)、带有盐水循环器(MMSF)和带有排热段(CMSF)的3种不同结构的多级闪蒸(Multi-stage flash,MSF)海水淡化装置分别与水电联产进行集成,并建立集成系统的数学模型,以最大经济效益为优化目标,探讨各操作参数和结构参数对集成系统性能的影响。结果表明,产水量一定时,3种集成系统的经济效益均随闪蒸级数的增大呈现出先增大后减小的变化趋势,而发电量则均出现下降的趋势。产水量Md增大时,CMSF和OTMSF系统的总经济效益均增大,且OTMSF的总经济效益高于CMSF;MMSF的经济效益明显低于前两种,其变化趋势是先升高后下降。
Desalination technology has become an effective solution to the shortage of freshwater resources. Three types of multi-stage flash (MSF) seawater desalination units, each of which is connected to a co-generation (OTMSF), a saltwater circulator (MMSF) and a three- And set up a mathematical model of the integrated system, the maximum economic efficiency as the optimization goal, to explore the various operating parameters and structural parameters of the integrated system performance. The results show that when the water production is constant, the economic benefits of the three integrated systems increase first and then decrease with the increase of flashover series, while the power generation all show a downward trend. When Md increases, the total economic benefits of CMSF and OTMSF systems increase, and the total economic benefits of OTMSF are higher than that of CMSF. The economic benefits of MMSF are obviously lower than those of the former two, and the trend is that MMSF and OTMSF firstly increase and then decrease.
