新型船用海水淡化装置的设计研究

针对目前市场上普遍使用的船用分离式板式造水机外壳体积大、成本高等问题,提出一种新型海水淡化装置。该装置通过换热板片的结构优化以及流道合理设计,摒弃原有装置厚重的铜制外壳,大大缩减装置体积、降低生产成本,安装维护更加方便。计算分析表明,新装置结构合理可靠,造水比、单位热耗率、单位淡水能耗等热力学性能指标均明显优于传统分离式造水机。该文借助ANSYS Workbench平台对新型海水淡化装置总体结构进行了力学性能仿真与分析,进一步验证了文中所设计的新型海水淡化装置的合理性与可靠性。

Design of New Marine Sea-Water Desalination Plant

A new sea-water desalination plant is developed according to the problems of large shell volume and high cost of the marine separating-plate type fresh water generator which is nowadays widely used in industry.The heavy copper shell is abandoned through the structural optimization of the heat exchange plate and reasonable design of the flow-path,resulting in the great reduction of the plant volume and production cost,as well as convenient installation and maintenance.The calculation and analysis indicate that the structure of the new plant is reasonable and reliable with the better thermodynamic properties,such as water production ratio,unit heat consumption and unit freshwater energy consumption,than those of the traditional separating-plate type fresh water generator.The mechanical properties of the new seawater desalination plant are simulated and analyzed by using the ANSYS Workbench Platform to further prove its rationality and reliability.
