针对管式太阳能蒸馏苦咸水淡化装置产水率低的问题,提出了一种多效管式太阳能苦咸水淡化装置.文章介绍了淡化装置的构造和运行原理,提出了两种强化管式太阳能苦咸水淡化装置内部传热传质效能的方法,测试了装置在定功率和定温度运行条件下蒸发温度、冷凝温度和产水量的变化,研究了对其第二效套筒风冷和水冷条件下,装置淡水产量随运行温度变化的规律.研究结果表明:在输入功率为335 W时,装置的性能系数达到1.37;当加热温度为80℃,对装置套筒进行风冷强化时,淡水产量为1.248 kg/h,比无风冷时的装置淡水产量增加了82.5%;当对装置套筒进行水冷强化时,淡水产量为1.556 kg/h,是无水冷时的装置淡水产量的2.28倍.%Considering the low productivity of tubular solar brackish water desalination system, this paper presents a novel multi-effect tubular solar brackish water desalination system. The structure and working principle of the device are introduced. Two methods of improving the heat and mass transfer performance of device are put forward. The evaporation and condensation temperature and distillation rate under both constant operation temperature and constant heating power conditions are experimental tested. Meanwhile,the productivity under air cooling and water cooling on the outer pipe with the heating temperature are investigated. The results indicate that the Gain Output Rate(GOR)of the system can reach 1.37 at the input power of 335 W. When the operating temperature of the device is 80 ℃,the yield of the system under air cooling is 1.248 kg/h, which is more than that under no air cooling by 82.5%. The productivity of the system under water cooling is 1.555 kg/h,which is 2.28 times more than that of the system under no water cooling.
