摘要
高能耗和高投资一直是阻碍反渗透海水淡化技术大范围推广应用的主要原因。为了促进反渗透海水淡化技术尤其是中小型反渗透海水淡化装置的推广应用,文章就一种10 t/d高效节能反渗透海水淡化装置进行了中试试验研究。由于采用了新研制的差动式能量回收装置,中试装置产出每吨淡水高压能耗只有3.6kW h,不考虑高压泵及电机自身损耗的影响时每吨淡水能耗为2.3kW h-2.7kW h,装置能耗得到显著降低,余压能量回收效率达到97%。装置产水流量稳定,产水质量较好,电导率可达290μS/cm。
High energy - consumption and high investment have been the main causes embarrassing the development of the reverse osmosis seawater desalination （SWRO） technology. To promote the popularization and application of the reverse osmosis seawater desalination technology especially the medium or small type SWRO device, this paper studies a 10t/d high - performance and energy - saving SWRO device. The RO body energy - consumption of the pilot device is only 3.6kWh per cubic meter freshwater, and the energy consumption is 2.3kWh - 2.7kWh per cubic meter freshwater if the efficiency of high - pressure pump and electric motor is 100%. And remaining energy recovery efficiency of the device reaches 97%. The output freshwater flux of the pilot device is steady, and the quality of the output freshwater whose conductivity is 290μS/cm is better.
