Description
一种综合利用风能和海水热能的冷热电水多联产*** Cold and hot water multi-generation system for comprehensive utilization of wind energy and seawater heat energy
技术领域 Technical field
本发明涉及于可再生能源的综合利用领域，具体是涉及一种针对岛屿及沿海偏远地 区综合利用风能和海水热能实现冷热电水多联产的独立***。 背景技术 The invention relates to the comprehensive utilization field of renewable energy, and particularly relates to an independent system for comprehensively utilizing wind energy and seawater heat energy to realize multi-generation of cold, heat and water in the remote areas of islands and coastal areas. Background technique
随着人类以及社会的发展， 人类脚步已经踏遍地球上每一个角落， 进入 21 世 纪以来， 经济持续的发展和生活水平不断的提高， 人类对水， 电， 冷， 热的需求量 越来越大， 尤其对于一些偏远地区以及岛屿， 无法在本地区获取资源， 又由于与大 陆的距离， 很难依靠大陆得到生活中所需的水， 电， 热， 冷等生活不可缺少的资源。 同时， 岛屿的供能问题也一直影响着国防边疆岛屿上驻守的战士们的生活质量。 因 此， 只有利用各地区的新能源才能从根本上解决以上问题， 而对于岛屿来说， 一般 拥有丰富的风能资源和海水热能资源。 With the development of human beings and society, human beings have stepped into every corner of the earth. Since the beginning of the 21st century, the continuous development of the economy and the improvement of living standards have increased the demand for water, electricity, cold and heat. Large, especially for some remote areas and islands, it is impossible to obtain resources in the region, and because of the distance from the mainland, it is difficult to rely on the mainland to obtain the indispensable resources for life, electricity, heat, cold and so on. At the same time, the island’s energy supply has also affected the quality of life of the soldiers stationed on the defence frontier islands. Therefore, only by using new energy sources in various regions can the above problems be fundamentally solved, and for islands, there are generally abundant wind energy resources and seawater thermal energy resources.
受全球能源危机和环境恶化的影响， 以风能为代表的新能源开发利用受到大多 数国家的重视， 并纷纷制订了相关的激励政策和措施。 受此影响， 全球风能开发利 用得到迅猛发展。 目前， 全球的风力发电增长速度惊人， 据 BTM统计数据显示 2010 年全球风电累计装机容量达到 199. 5GW。 我国继续保持风电设备生产和风电场开发 快速发展的强劲势头。据中国可再生能源学会风能专业委员会（CWEA)的统计， 2010 年我国除台湾省外其他地区共新增风电装机 12904台，装机容量达 18. 93GW, 自 2009 年后继续保持全球新增装机容量第一的排名。 Affected by the global energy crisis and environmental degradation, the development and utilization of new energy represented by wind energy has been valued by most countries, and relevant incentive policies and measures have been formulated. Affected by this, the development of global wind energy development has been rapidly developed. At present, the global wind power generation growth rate is amazing. According to BTM statistics, the cumulative installed capacity of global wind power in 2010 reached 19.5GW. China continues to maintain the strong momentum of rapid development of wind power equipment production and wind farm development. According to the statistics of the Wind Energy Professional Committee of China Renewable Energy Society (CWEA), in 2010, China added 12,904 wind power installations in other regions except Taiwan Province, with an installed capacity of 18.93 GW. Since 2009, it has continued to maintain new installed capacity worldwide. The first ranking.
然而风能资源存在不稳定性的特点： 风速时常变化， 能量供应不稳定， 具有间 歇性， 波动性， 同时风能发电也存在并网问题， 在一定程度上限制了风力发电的发 展， 因此， 需要将不稳定的风能与储能***联合起来才能有效的利用风资源。 However, wind energy resources are characterized by instability: wind speed changes frequently, energy supply is unstable, intermittent, and volatility. At the same time, wind power generation also has grid connection problems, which limits the development of wind power generation to some extent. Unstable wind energy combined with energy storage systems can make effective use of wind resources.
从长远角度来看， 发展海水淡化， 不论从经济上， 还是从环境上都更加可行。 海水淡化水源稳定、 清洁， 产水成本逐渐降低， 已经受到越来越多国家， 尤其是干 旱缺水国家的重视。 事实上， 世界范围的普遍缺水已经使海水淡化技术从中东的沙 漠地区扩展到全球的主要沿海城市， 并形成了海水淡化水的生产销售和海水淡化设 备制造两大产业。 因此， 海水淡化作为开发新水源的一种技术已经确定无疑地成了 全世界的必然趋势。 然而， 海水淡化耗能多， 大力发展便宜的可再生能源并用于海
水淡化将是解决海水淡化高成本的重要途径。 In the long run, the development of desalination is more feasible, both economically and environmentally. The desalination water source is stable and clean, and the cost of water production is gradually decreasing. It has been paid more and more attention by countries, especially those with drought and water shortage. In fact, the widespread shortage of water around the world has enabled desalination technology to expand from the desert regions of the Middle East to the major coastal cities around the world, and has formed two major industries: production and sales of desalinated water and desalination equipment manufacturing. Therefore, desalination as a technology to develop new water sources has definitely become an inevitable trend in the world. However, desalination consumes more energy, vigorously develops cheap renewable energy and uses it in the sea. Water desalination will be an important way to solve the high cost of seawater desalination.
海水淡化方法按照分离过程分类， 可分为热过程和膜过程两类。 热过程是利用 热能使海水蒸发， 再通过水蒸汽的冷凝得到淡水。 热过程有多级闪蒸（(Multi stage Flash, MSF)、 多效蒸熘（（Multi Effect Distillation, ME)、 蒸汽压缩（vapor Compression, VC)等； 膜过程则是利用分离膜对水和盐的选择透过性， 将盐分截留 或移走， 得到淡水的方法。 膜过程有反渗透法（（Reverse Osmosis, R0)、 和电渗析 ((Electro DialysisED)等。 目前比较常用的海水淡化方法主要有多级闪蒸 (Multi-Stage Flash, MSF) 、 低温多效蒸熘 (Multiple Effect Distillation, MED) 和反渗透法 （Reverse Osmosis, R0) 等 3种， 其中反渗透法海水淡化技术因 其能耗低、 ***安装维护相对简单等优点， 以及反渗透膜元件在材料、 结构等方面 不断取得突破， 反渗透海水淡化技术近几十年来取得了飞跃发展， 使得反渗透技术 己经成为海水淡化、 苦咸水淡化、 纯水和超纯水制备最经济的手段， 目前已得到了 广泛的应用。 The desalination method is classified according to the separation process and can be divided into two types: thermal process and membrane process. The thermal process uses heat to evaporate seawater and then obtain fresh water by condensation of water vapor. The thermal process has multi-stage flash (MSF), Multi Effect Distillation (ME), vapor compression (VC), etc.; the membrane process uses a separation membrane for water and salt. The choice of permeability, interception or removal of salt, to obtain fresh water. The membrane process has reverse Osmosis (R0), and electrodialysis (Electro DialysisED). Currently more commonly used seawater desalination methods There are three types of Multi-Stage Flash (MSF), Multiple Effect Distillation (MED) and Reverse Osmosis (R0), among which the reverse osmosis seawater desalination technology The advantages of low consumption, relatively simple installation and maintenance, and breakthroughs in materials and structures of reverse osmosis membrane elements have made rapid progress in reverse osmosis desalination technology, which has made reverse osmosis technology become desalination. The most economical means of brackish water desalination, pure water and ultrapure water preparation has been widely used.
地源热泵利用土壤或水体温度冬季为 12-22°C， 温度比环境空气温度高， 热泵循环 的蒸发温度提高， 能效比也提高； 土壤或水体温度夏季为 18-32°C， 温度比环境空气温 度低， 制冷***冷凝温度降低， 使得冷却效果好于风冷式和冷却塔式， 机组效率大大提 高， 可以节约 30-40%的供热制冷空调的运行费用， 1KW的电能可以得到 4KW以上的热 量或 5KW以上冷量。 因此将地源热泵用于岛屿具有很好的发展前景。 发明内容 The ground source heat pump uses the soil or water body temperature to be 12-22 ° C in winter, the temperature is higher than the ambient air temperature, the evaporation temperature of the heat pump cycle is increased, and the energy efficiency ratio is also improved; the soil or water body temperature is 18-32 ° C in summer, and the temperature is higher than the environment. The air temperature is low, the condensing temperature of the refrigeration system is reduced, so that the cooling effect is better than that of the air-cooled and cooling towers. The efficiency of the unit is greatly improved, and the operating cost of the heating and cooling air conditioner can be saved by 30-40%. The electric energy of 1KW can be more than 4KW. The heat or the amount of cold above 5KW. Therefore, the use of ground source heat pumps for islands has a good development prospect. Summary of the invention
