设计一种由平板太阳集热器和海水淡化单元组成的多效同轴竖管降膜蒸发式太阳能海水淡化装置。研究装置的能量流动情况,并在实际天气条件下对装置进行性能测试,给出该装置的产水量和运行温度随运行时间、辐照度的变化曲线。结果表明,装置在实际天气条件下,日产水量最高达到9.92 kg,最大产水速率为2.0 kg/h,是一种理想的太阳能海水淡化器。
A multi-effect coaxial vertical tube falling film evaporative solar desalination unit consisting of a flat-panel solar collector and a desalination unit is designed. The energy flow of the device is studied. The performance of the device is tested under actual weather conditions. The curves of water production and operating temperature of the device with the running time and irradiance are given. The results show that under actual weather conditions, the device can produce up to 9.92 kg of water per day and the maximum water production rate of 2.0 kg / h, which is an ideal solar desalination device.
