The utility model provides a device for the function of both aquaculture and seawater desalination in the South China Sea, which comprises a POLYWAVE slope, a breeding room, a pool, a water turbine, a filter tube, a freshwater collection room and a vacuum pump. Using the rich wave resources and complex wave conditions in the South China Sea, the device moves up and waves over the POLYWAVE slope through waves and enters a pool to obtain potential energy. Then using the rotation of the hydraulic turbine and the mechanical transmission of the crank connecting rod, the potential energy is converted into the kinetic energy of the vacuum pump, and the vacuum pump is driven to work. The large pressure difference is produced inside and outside the filter tube, and the seawater desalination is realized. The breaking effect when the waves climb high and the bubbles generated by the air volume when the waves impact the slit are raised to the aquaculture water body. Gas transmission provides high quality aquaculture environment. The utility model combines the wave energy industry with the fishing industry. In solving the shortage of freshwater resources in the South China Sea, the development of fishery is taken into consideration and the social, economic and environmental benefits are achieved.
【技术实现步骤摘要】
一种适用于南海的兼具养殖和海水淡化功能的装置
本技术涉及海水淡化领域,尤其涉及一种适用于南海的兼具养殖和海水淡化功能的装置。技术背景淡水资源匮乏已经成为威胁人类生存的严重问题。我国虽然水资源总量大,居世界第六位,但人均占有量仅为世界的四分之一,居第121位。长久以来,沿海城市及岛屿均面临供水严重不足的问题,淡水资源的缺乏在一定程度上制约着我国社会和经济的发展。利用我国丰富的海水资源,通过海水淡化技术,将海水提纯为淡水,以满足沿海城市及岛屿对淡水资源的需求,是解决我国沿海地区淡水资源匮乏问题的一项重要举措。反渗透海水淡化法作为海水淡化的主要方法之一,是目前最具经济价值和社会效益的淡水制备方法。其利用选择透过性膜两侧水体的渗透压差,将水分子与盐分以及其他杂质进行分离,从而得到淡水,达到海水淡化的目的。传统的反渗透海水淡化装置需依靠电力驱动高压泵工作,其运行成本较高,尤其是在离岸海岛,代价更大。若能采取一定措施降低反渗透海水淡化对电能的依赖,即可有效降低海水淡化的成本,提升反渗透海水淡化方法的推广性,增强海水淡化的经济和社会价值。南海是新生代热带海洋,是中国三大边缘 ...
