海水浓度差发电
electric power of ocean energy from concentration gradients
约有300亿kw,可供利用的大约有26亿kw,其中中国可以开发利用的估计有1亿kw。 海水浓度差发电有渗透压法、渗析电池法和燕汽压差法等几种不同类型. (l)渗透压法:利用浓度不同溶液之间的渗透压差发电。这种方法必须通过半透膜才能实现。 (2)渗析电池法:利用不同浓度溶液之间的电位差发电。又称浓淡电池法。这种方法必须使用两种不同的膜,即阴离子交换膜与阳离子交换膜才能实现。 (3)蒸汽压差法:利用不同浓度溶液之间饱和燕汽压的不同来发电。 世界上最早提出利用浓度差发电的是以色列科学家洛布(L,b),时间是1973年。以后,美国、瑞典、日本等国相继开始了这方面的研究,并制成了实验发电装里.中国于1979年开始这方面的研究,1981年发表第一篇研究论文,1985年7月14日在西安采用半渗透膜研制成首台干涸盐湖浓度差实验室发电装t并发电。半渗透膜面积为14 mZ。试验中溶剂(淡水)向溶剂(浓盐水)渗透,溶液水柱升高10m,水轮机发电机组电功率为0.9一1.ZW。 从各国浓度差发电的研究中可以看出,首先开发并用于发电的浓度差能,是高浓度盐水与淡水之间的高品位能源。hO一shu,nongdueho fad一on海水浓度差发电(electrie power of oceanenergy from eoneentration gradients)利用海水浓度差能发电。不同浓度的溶液之间所存在的化学潜能,称为浓度差能。海水与河水之间的浓度差能,称为海水浓度差能. 据有关专家估计,世界各河流区域的浓度差能t
