摘要:
 研制了一台可用于边远海域的小型高效反渗透海水淡化装置(规模为10t/d),并进行了多工况性能试验研究。定量研究了装置在不同操作压力、操作温度条件下,系统产水量、产水电导率、产水能耗等的运行规律。试验结果表明,装置的操作压力、试验温度对性能影响比较大。操作压力越高,系统产水量越大,产水电导率越低,吨水能耗越低;操作温度越高,系统产水量越大,产水电导率略有提高,吨水能耗下降。当产水量一定时,操作压力与操作温度呈相反方向变化。能量回收装置的使用对降低制水能耗效果明显 ,操作压力为6MPa时,吨水能耗降低58%。
 Develop an efficient small-scale reverse osmosis seawater desalination device(10t/d)used in outlying sea, and do a great deal of experiments in diverse working condition on its performance. Study the output freshwater quantity、the output freshwater conductivity、the energy consumption, etc of the reverse osmosis seawater desalination in fixed quantity. The experiment result indicates that the operating pressure and the operating temperature are the main effect to the reverse osmosis seawater desalination device. The higher the operating pressure, the more the output freshwater quantity, the lower the output freshwater conductivity, the less the energy consumption of per ton freshwater.The higher the operating temperature, the more the output freshwater quantity, the higher the output freshwater conductivity, the less the energy consumption of per ton freshwater.The operating pressure and the operating temperature vary differently in fixed output water quantity. The energy recovery device is very important to energy consumption of per ton freshwater. When the operating pressure is 6MPa, the energy consumption of per ton freshwater can reduce by 58%.
