摘要:
根据太阳能辐射随时间的变化规律，建立了热水驱动的顺流五效蒸馏/闪蒸太阳能海水淡化系统动态数学模型，并对在太阳能辐射强度为730 W/m2，海水平均温度为25℃条件下，日产淡水量达到10吨的太阳能海水淡化系统进行静态设计计算，确定每效海水蒸馏器设计负荷及结构参数，为太阳能海水淡化系统设计和动态模拟奠定基础。
According to the variation regulation of the solar radiation intensity with time, the dynamic mathematic models of the down-flow five effect distillation/flash desalination system powered by solar energy were developed. Under the design conditions which the solar radiation intensity is 730 W/m2, the brine temperature is 25°C and the desalination capacity is 10 ton per day, the static design calculation for the system had be done and the heat loads and the structure parameters of each distillatory in the system were determined. The results lay the foundations of the design and simulation for the system.
