摘　　要：提出一种新型横管式太阳能苦咸水淡化装置,介绍装置的工作原理,通过建立装置内传热传质关系,得到单效及两效横管式太阳能苦咸水淡化装置的淡水产量预测值。用电加热管代替太阳能集热系统,对单效和两效装置在稳态运行时测点温度变化和产水速率进行测试。结果表明:两个装置稳态运行时,蒸汽主要在套管内上部进行凝结,产水速率均随加热温度的升高而增大,两效淡化装置在加热温度为80℃时的淡水产量为0.728 kg/h,是单效装置的2.1倍,实验测试值与理论计算值随温度变化趋势一致,两效淡化装置性能系数可达1.67。A novel horizontal tubular style solar brackish water desalination device was presented. The structure characteristics and working principle of the unit were introduced. The internal heat and mass transfer mechanism of the device were analyzed, the semi-empirical expression of the water yield was given. In addition, the water yield and temperature variation of the single-effect and double-effect devices were tested with an electric heater to simulate solar collector under the fixed heating temperature condition, respectively. The results show that the most condensation takes place on the upper side of the tubular shell. The water yield increases with the increase of heating temperature. When the heating temperature is 80 ~C, the water yield rate of the double-effect device can reach 0.725 kg/h. It is increased by 2.1 times compared with that of the single-effect device. Then the theoretical results are compared with the experimental results, and it is found that the trend of theoretical water yield rate is consistent with the experimental results. The GOR of the double-effect device working under environmental pressure can reach to 1.67.
