带肋片多效管式海水淡化装置的实验研究

EXPERIMENTAL STUDY OF MULTI-EFFECT TUBULAR DESALINATION STILL WITH FINS

设计一种带肋片多效管式海水淡化装置并利用模拟热源对装置进行实验研究。实验中对系统稳态产水性能进行测试,给出系统在不同运行温度、压力下的产水速率和性能系数。实验结果表明:装置小时产水量随运行温度升高而增大,80℃时小时产水量为0.59 kg/h;对装置进行抽真空后装置的小时产水量增加明显,在运行温度为70℃压力为0.31 k Pa时,小时产水量最大为1.19 kg/h;装置的性能系数最高达1.5,定功率运行10 h,产水量最高为8.58 kg。

A multi-effect tubular desalination still with fins was designed and a simulated heat source was used in the experimental research. The water production performance in steady status was tested in the experiment so as to figure out the water yield and performance coefficients in different temperatures and pressures. The results show that the water yield per hour increases as the temperature rises, reaching 0.59 kg/h when the temperature is 80℃; The water yield per hour has a significant increase after vacuumizing the still, reaching 1.19 kg/h when the temperature is 70℃ and the pressure is 0.31 kPa; and that the maximum performance coefficient is about 1.5 and the maximum water yield is 8.58 kg when the still runs for 10 hours at a fixed power.
