摘要
针对管式太阳能海水淡化装置淡水产量较低的问题,提出一种新的具有回热功能的竖管式太阳能海水淡化装置,通过建立装置内部传热传质关系,得到竖管式太阳能海水淡化装置理论淡水产量预测计算方法,分别对单效和两效淡化装置在回热和非回热运行条件下,定温运行工况时的淡水产量、进料海水温度等进行试验研究。结果表明,运行温度为80℃,两效淡化装置在回热运行条件下,淡水产量比非回热运行条件时增加13.32%,单效淡化装置在回热运行条件下,淡水产量比非回热运行条件时增加32.83%,进料海水温度明显升高,装置淡水产量试验测试值与理论计算值趋势一致,吻合度较好。
This paper presents a novel vertical tubular solar seawater desalination device with heat recovery,with anaim to overcome the major drawbacks of lower productivity of tubular solar seawater desalination device.The heat andmass transfer process within the device is illustrated and the prediction of water production is derived.An experimentalinvestigation was carried out to study the water yield and the feed water temperature of the single-effect and double-effectdevices under heat recovery and non heat recovery process,respectively.The results indicated that when the operatingtemperature is 80 ℃,the water yield of the double-effect device under heat recovery process is 13.32% higher than thatof the device under non heat recovery process.In addition,the water yield of the single-effect device under heat recoveryprocess is 32.83% higher than that of the device under non heat recovery process.The feed water temperature of thedevices can be enhanced obviously.The numerical results have been calculated and a consistent agreement with theexperimental results.
