| Abstract | 海水淡化作为淡水资源的替代与增量技术，对于解决沿海（近海）地区淡水资源短缺起着越来越重要的作用。尤其是在边远海域例如偏远海岛和海上原油开发钻井平台以及大型舰船等地方，由于高能耗和高设备投资在一定程度上影响了中小型海水淡化装置的应用，因此开发一种新型的高效节能的海水淡化装置非常有必要，会有力地促进海洋开发。 本文第一章主要介绍了海水淡化的主要方法、国内外海水淡化的发展和现状以及反渗透海水淡化当今主要的研究方向。第二章主要介绍了反渗透的基本理论和基本知识。第三章具体设计了海水淡化装置，由预处理系统、反渗透系统、能量回收系统三部分设计组成。第四章对建成的海水淡化装置进行了实验研究和分析，得出了一系列的结果和装置运行规律。第五章建立了能量回收装置的数学模型以及效率模型，对其性能进行了研究和评价。 本淡化装置相对于以往的中小型海水淡化装置是一种高效节能的淡化装置，吨水能耗低，投资有很大降低。装置采用了新型差动式能量回收器，相对于以往出现过的能量回收器来说，有效的改善了阀门换向时引起的系统压力波动以及淡水产量波动问题，并且本能量回收器之后不需要再采用增压泵，简化了工艺。淡化装置制水吨水总能耗能达到5kWh/m3，其中总的高压能耗（考虑电机和高压泵自身损耗时）为3.6kWh/m3，其中高压能耗（不考虑电机和高压泵自身损耗时）达到了2.4kWh/m3。 关键词：海水淡化；反渗透；高效节能；能量回收. |
| Other Abstract | As the advanced technology to make freshwater, seawater desalination plays more and more important roles in solving the scarcity of freshwater resource in coastal areas and offshore areas. Especially in the remote sea area such as the remote islands, oil drilling platform in the sea and big warships, high energy consumption and large investment limit the application of medium and small type seawater desalination device. So it is necessary to develop a new type high-efficiency and energy-saving seawater desalination device to boost the ocean development. First of all, the main seawater desalination methods, the development and actuality of seawater desalination in and abroad and the main study aspect of seawater reverse osmosis (SWRO) desalination today are introduced in the first chapter of this thesis. The second chapter is mainly about the basic theory and elementary knowledge of reverse osmosis (RO). Then the 10t/d SWRO device is designed in the third chapter. The design is made up of three parts: pretreatment system, RO system and energy recovery system. We do a series of experiment study and analysis to the SWRO device in the fourth chapter, and get a lot of results and many running rules. In the fifth chapter, we set up the mathematic model of energy recovery device (ERD) and efficiency model, study and evaluate the performance of the ERD. The 10t/d SWRO device is a high-efficiency and energy-saving desalination device relative to other medium and small type SWRO devices, and it is lower investment. The 10t/d SWRO device uses newly-designed differential type ERD, so the pressure and freshwater output fluctuations coming from on-off of the electric valve are eliminated almost. And we needn’t use boosting pump after ERD as the other positive-displacement ERD, so it can simplify the process flow. The total energy consumption for per ton freshwater of the 10t/d SWRO device is about 5 kWh/m3.Thereinto gross high pressure energy consumption (considering the dissipation of the electric motor and high-pressure pump) is 3.6 kWh/m3, and the high pressure energy consumption (not considering the dissipation of the electric motor and high-pressure pump) is only about 2.4 kWh/m3. Keyword: seawater desalination; reverse osmosis (RO); high-efficiency and energy saving; energy recovery device (ERD). |
