Description

一种太阳能空气制水发电系统
技术领域
本发明属于制水机技术领域，涉及一种空气制水系统，具体地说涉及一种太阳能空气制水发电系统。
背景技术
水是生命之源，也是人身体的重要组成要素，从全球范围讲，水是连接所有生态系统的纽带，水在自然环境中对于生物和人类的生存来说有着决定性的意义，也是经济发展、社会进步不可缺少的重要自然资源。但随着工业化进程不断推进、气候变化，水的问题变得复杂多变，尤其是水资源紧缺、水污染严重、水环境恶化，人类对水资源的需求以惊人的速度扩大，但同时不断有干净的水资源被污染，世界水论坛提供的联合国水资源世界评估报告显示，全世界每天约有200吨垃圾倒进河流、湖泊和小溪，每升废水会污染8升淡水，缺水已直接威胁到人类的生存和发展。
如何解决世界性缺水问题，不少国家科学家对此不懈研究，试图找到最适合的方法治水，比如从化学实验室通过化学反应制水，或通过高科技手段将海水淡化提取水。上述方法中，化学方法制水存在成本高、风险大的问题，而海水淡化装置结构复杂，水运输成本较高。
为解决这些问题，科研人员逐渐关注到一般不易察觉的事物—空气，并逐渐对空气制水进行开发，由于地面的水分蒸发到空气中使得空气也含有一定水分，尤其是在许多南方地区，降雨量丰富、空气湿度较大，空气中含有大量水分，如能将这些水分加以充分利用，将会极大缓解各种灾难地区、野外、偏远地区以及淡水资源匮乏地区缺少饮用水的问题，可以直接打破地域性的限制，只要有空气即可制得水源。目前已有的一些空气制水装置通常采用电力作为能源，不够节能环保，对于电力紧缺的地方应用较受限制，并且现有空气制水装置功能较为单一，仅能够制水，对于电力紧缺的地区和野外，难以保障能源来源。
发明内容
为此，本发明所要解决的技术问题在于现有空气制水装置通常由电力驱动，不够节能环保，且不利于电力紧缺的区域或也外使用，从而提出一种集制水与发电功能的利用太阳光的太阳能空气制水发电系统。

（1）光热过程：太阳光经过以特定角度设置的定光镜被反射到集热装置2上，太阳光的热能将集热装置2中的工质（如水）加热使之变为蒸汽，水蒸汽进入蓄热装置3后进行热交换，热交换完成后的工质再次变为液体，被加热泵5输送回集热装置2，完成一个加热循环，蓄热装置3同时将部分热能储存以使后续无阳光时可持续用于后续发电、制水，热交换后的热工质。
（2）发电过程：在蓄热装置3中将经软化处理的水加热成为水蒸汽，蒸汽的热能一部分供给汽轮机7，一部分供给制冷装置12，供给汽轮机7的蒸汽热能带动汽轮机7工作，进而由汽轮机7带动发电机运转进行发电，发电得到的电能经过稳压装置9的整流、滤波和稳压作用后进入蓄电装置10，进行蓄能，以保证在没有阳光的情况下不影响持续供电，同时电流经逆变器11转换为交流电后一部分用于系统自身供电，一部分并入电网用于产生收益。
（3）制水过程：制冷装置12在蓄热装置3产生的蒸汽驱动下产生冷量，冷量由冷媒水带进冷凝制水装置13，进行冷凝制水，经过热交换后的冷媒水由循环泵输送回制冷装置12，完成一个循环。空气在引风装置15的作用下被引入散热装置14，遇冷，凝结为水珠被收集到冷凝制水装置13中，冷凝制水装置13中的水大部分进入水质净化装置中依次经过4级过滤和紫外杀菌后可以直接饮用，少部分水进入冷却循环单元作为循环冷却水损耗补充。而且冷凝装置4产生的冷空气进入到散热装置14中后，在散热装置14 中进行热交换，降低散热装置14中的水温，散热装置14内的冷却后的水进入冷却循环单元后由可以降低冷却循环单元内水的温度，实现了能量的综合利用。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
