Description

太阳能光热发电系统
本申请要求申请日为2018年01月11日、申请号为201810026166.9、名称为“一种渔光互补的槽式太阳能光热发电系统”的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本公开涉及新能源技术领域，例如涉及一种太阳能光热发电系统。
背景技术
随着社会的发展和进步，一些地区，人口越来越多，土地需求越来越大，土地的价格节节攀升，太阳能电站安装所需的土地成为了问题。
养殖渔业，又称水产养殖，是指在岸上由人工所开的鱼塘中，养殖鱼类或各种海鲜，以供食用。有些种类的鱼不喜欢阳光所以养殖的时候需要在鱼塘上搭建遮阳板，为鱼避光。
发明内容
本公开提供一种太阳能光热发电系统，能够进行渔光互补，节能环保。
一种渔光互补的槽式太阳能光热发电系统，包括：并排设置的多个水塘，相邻的两个所述水塘之间设置有安装区；多个聚光集热装置，多个所述聚光集热装置均布于所述水塘四周；以及储热装置，架设于所述安装区内。
附图说明
图1是一实施例中储热装置的结构示意图；
图2是一实施例中聚光集热装置的结构示意图；
图3是一实施例中太阳能光热发电系统的水塘的分布示意图。
具体实施方式
本实施例提供一种不占用土地面积，且可为鱼塘起到遮阳避光的作用的一种渔光互补的太阳能分布式发电系统。渔光互补是通过合理地布局，在鱼塘内设置反射镜组件，养鱼的同时进行发电，从而使得渔民水产、电力双丰收。相关技术中，“渔光互补”条件下水产养殖存在的主要问题是晶硅太阳能电池板遮档阳光，造成水温偏低，会对水产的正常生长有一定的影响。此外，渔光互补多用光伏发电，但是存在光伏发电并网难，且会对环境造成污染。
结合图1至图3所示，本实施例提供了一种渔光互补的槽式太阳能光热发电系统，包括多个水塘100及多个聚光集热装置1，多个水塘100并排设置，多个聚 光集热装置1均布于所述水塘100四周，储热装置2架设于相邻所述水塘100之间的安装区101内。
本实施例中，所述储热装置2包括集热场21、换热器22、第一介质储存装置23、第二介质储存装置24及蒸气发生器25，集热场21由多个熔盐罐20组合而成，换热器22与所述集热场21并联，第一介质储存装置23和第二介质储存装置24均与所述换热器22相连接，蒸气发生器25与所述换热器22并联，所述蒸气发生器25与外部负载30相连接，所述外部负载30包括供暖装置3和发电装置4，供暖装置3和发电装置4均与所述蒸气发生器25相连接，所述发电装置4设置为与所述蒸气发生器25相连接的汽轮发电机，所述汽轮发电机的排水口通过给水泵41与所述蒸气发生器25贯通连接。
上述实施例中，当阳光充足时，从集热场21来的部分载热流体与从第二介质储存装置24来的熔盐进入换热器22中进行热交换，熔盐升温后进入第一介质储存装置23储存起来。载热流体则重回集热场21进行吸热升温。阳光不足时，第一介质储存装置23内的熔盐作为载热流体流入换热器22，反加热温度较低的载热流体，熔盐降温后被打入熔盐罐20中，以此得到循环利用。
本实施例中，所述聚光集热装置1包括地桩11、支撑架12、斜梁13、槽式反射镜14及定位梁15。其中，地桩11安装于所述水塘100水底，支撑架12垂直紧固于所述地桩11顶部，斜梁13倾斜枢接于所述支撑架12顶部，槽式反射镜14架设于所述斜梁13上表面，定位梁15设置于所述斜梁13下底面，所述定位梁15沿周向均布有多个定位孔151，所述定位孔151与所述支撑架12上的安装孔122通过定位销40相连接，所述斜梁13的下底面设置有转轴(图中未示出)，所述转轴与所述支撑架12的枢接块121两侧壁的轴孔(图中未示出)相配合，所述槽式反射镜14呈弧形设置。
采用上述结构设计的聚光集热装置1能够通过改变定位梁15上的定位孔151与支撑架12上的安装孔122的装配位置，进而改变槽式反射镜14的反光角度，以此优化聚光集热装置1的光照效率，进而有效提升储热装置2的能量转换效率。
本公开包括多个水塘100、多个聚光集热装置1及多个聚光集热装置1，多个水塘100并排设置，多个聚光集热装置1均布于所述水塘100四周，储热装置2架设于相邻所述水塘100之间的安装区101内。上述结构设计，能够通过多个聚光集热装置的设置，为水塘100中的水产品提供一定区域的避光场所，同时，还能够通过储热装置对太阳能的转化，为外部装置提供源源不断的清洁能源。
