Abstract

一种物理储存能量的方式,为解决目前能量储存方式的效率低下,占用空间和污染等问题,本发明是采用将气态空气压缩致冷成液态空气进行能量储存,在需要释放能量时再将液体空气受热汽化释放能量,这样可以高效、无污染、占用空间小地储存能量,可以用于峰谷能量调剂。

Description

液气储能
技术领域
本发明涉及一种能量保存方式,尤其是物理储存能量的方式。
背景技术
目前的能量储存方式有化学方式,但会带来化学污染。采用水位扬高储能,但因为抽水机和发电机的能量转化效率都只接近50%,这样会使最终储存效率不到25%,而且占用物理空间很大。
发明内容
本发明的任务是设计一种可以高效、无污染、空间小的能量储存方式。
本发明是采用将气态空气压缩致冷成液态空气进行能量储存,在需要释放能量时再将液体空气受热汽化释放能量。
由于空气资源的免费性,成本低;气体液化压缩比为1∶800-1500,能量储存密度高;空气的液体和气体转化,无化学污染;储存释放过程简易,转化率提高到40%左右。
具体实施方式
在进行气体压缩时,需要边降温边压缩,这样液化速度就可以加快。而在进行释放能量时,需要充分吸收利用外界热量,这样转化率会有所提高。
另外,一般液态气体在常温下压力为44-50标准气压,为方便储存和降低储存成本,可以将液气储存罐深埋在140-180米深处,这样就可以平衡大部分内外压力。
在气体液化过程中,需要多级压缩才能实施气体液化,可以结合高压气体自蒸发致冷等多种手段提高压缩效率。
