具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
下面参考附图描述本公开实施例的熔盐储热装置100。如图1至图3所示，根据本公开实施例的熔盐储热装置100包括多个熔盐储箱1、多个溢流管2、循环管3、换热器4和循环泵5。
熔盐储箱1适于存储熔盐，每个熔盐储箱1具有溢流口11和位于溢流口11下方的熔盐进口12。多个熔盐储箱1沿上下方向排布，相邻两个熔盐储箱1中位于上方一者的溢流口11与相邻两个熔盐储箱1中位于下方一者的熔盐进口12相连，以适于熔盐储箱1内的熔盐可溢流至其下方的熔盐储箱1。任意相邻两个熔盐储箱1通过对应的溢流管2相连，且溢流管2的一端与对应的溢流口11连通，另一端与对应的熔盐进口12连通。
循环管3的进口31与多个熔盐储箱1中位于最下方一者的溢流口11相连，循环管3的出口32与多个熔盐储箱1中位于最上方一者的熔盐进口12相连。换热器4设在循环管3上以适于与循环管3内的熔盐换热。循环泵5设于循环管3或溢流管2，循环泵5适于驱动熔盐循环流动。
根据本公开实施例的熔盐储热装置100通过设置多个适于存储熔盐的熔盐储箱1，从而可提高熔盐储热装置100的熔盐存储量，进而可提高熔盐储热装置100的储热能力。且多个熔盐储箱1沿上下方向排布，相邻两个熔盐储箱1中位于上方一者的溢流口11与相邻两个熔盐储箱1中位于下方一者的熔盐进口12相连，以适于熔盐储箱1内的熔盐可溢流至其下方的熔盐储箱1。由此，在循环泵5驱动熔盐循环流动并与换热器4换热后，熔盐通过循环管3的出口32进入多个熔盐储箱1中位于最上方一者并与最上方的熔盐储箱1内的熔 盐进行换热。随着最上方的熔盐储箱1内的熔盐逐渐增多，最上方的熔盐储箱1的溢流口11将溢流出一部分熔盐并在重力的作用下通过溢流管2流动至与最上方的熔盐储箱1相邻的熔盐储箱1内并与该熔盐储箱1内的熔盐换热。在循环泵5持续的工作中，相邻两个熔盐储箱1中位于上方的一者内的熔盐逐渐增多后，可通过相邻两个熔盐储箱1中位于上方的一者的溢流口11溢流出一部分熔盐至相邻两个熔盐储箱1中位于下方的一者内并与相邻两个熔盐储箱1中位于下方的一者内的熔盐进行换热。也就是说，多个沿上下方向排布的熔盐储箱1可通过溢流口11将相邻两个熔盐储箱1中位于上方的一者内的熔盐输送至相邻两个熔盐储箱1中位于下方的一者内并进行换热。从而使得多个沿上下方向排布的熔盐储箱1之间输送熔盐较为方便且节约能源，进而使得熔盐储热装置100即可扩大熔盐存储量的基础上设置条件简单，节约生产成本。
因此，根据本公开实施例的熔盐储热装置100具有便于扩大熔盐存储量、便于设置和节约成本的优点。
如图1至图3所示，根据本公开实施例的熔盐储热装置100包括多个熔盐储箱1、多个溢流管2、循环管3、换热器4和循环泵5。
多个熔盐储箱1沿上下方向排布，熔盐储箱1适于存储熔盐，熔盐储箱1的数量至少为2个，以便提高熔盐储热装置100的熔盐存储量。每个熔盐储箱1具有溢流口11和位于溢流口11下方的熔盐进口12，且熔盐储箱1的顶部为敞口，由此可使得熔盐储箱1内的气压与外界一致，从而便于熔盐储箱1内的熔盐从溢流口11向外溢流。上下方向如图1和图2中的箭头所示。例如，多个熔盐储箱1中的每一者包括底板13和与底板13相连的第一侧板14、第二侧板15、第三侧板16和第四侧板17，第一侧板14和第三侧板16相对设置，第二侧板15和第四侧板17相对设置。
如图2所示，在一些实施例中，每个熔盐储箱1的溢流口11设在靠近熔盐储箱1的上边缘位置，每个熔盐储箱1的熔盐出口设在靠近熔盐储箱1的下边缘位置。由此可使得每个熔盐储箱1可存储较多的熔盐，从而增加熔盐储热装置100熔盐存储量。
相邻两个熔盐储箱1中位于上方一者的溢流口11与相邻两个熔盐储箱1中位于下方一者的熔盐进口12相连，以适于熔盐储箱1内的熔盐可溢流至其下方的熔盐储箱1。任意相邻两个熔盐储箱1通过对应的溢流管2相连，且溢流管2的一端与对应的溢流口11连通，另一端与对应的熔盐进口12连通。具体地，溢流管2的一端(上端)与相邻两个熔盐储箱1中位于上方一者的溢流口11相连，溢流管2的另一端(下端)与相邻两个熔盐储箱1中位于下方一者的熔盐进口12相连。由此可使得相邻两个熔盐储箱1中位于上方一者内在持续注入熔盐后，相邻两个熔盐储箱1中位于上方一者可通过其上的溢流口11将一部分熔盐通过溢流管2溢流至相邻两个熔盐储箱1中位于下方一者内。
循环管3的进口31与多个熔盐储箱1中位于最下方一者的溢流口11相连，循环管3的出口32与多个熔盐储箱1中位于最上方一者的熔盐进口12相连。换热器4设在循环管3上以适于与循环管3内的熔盐换热。循环泵5设于循环管3或溢流管2，循环泵5适于驱动熔盐循环流动。由此，可使得在循环泵5的作用下多个熔盐储箱1中位于最下方一者内的熔盐进入循环管3内并与换热器换热后输送至最上方的熔盐储箱1内进行换热。
在一些实施例中，循环泵5设于循环管3，且循环泵5位于换热器4和最下方熔盐储箱1之间。从而便于快速将多个熔盐储箱1中位于最下方一者内的熔盐输送至循环管3内与换热器4进行换热，进而提高换热效率。
如图1和图2所示，在一些实施例中，每个熔盐储箱1包括多个溢流口11和多个熔盐进口12，多个溢流口11沿着熔盐储箱1的周向间隔排布，多个熔盐进口12沿着熔盐储箱1的周向间隔排布。多个溢流口11和多个熔盐进口12便于相邻两个熔盐储箱1之间可根据实际情况去设置溢流管2的位置和数量。具体地，溢流管2与相邻两个熔盐储箱1同一侧的溢流口11和熔盐进口12相连，可便于溢流管2的安装。当需要提高相邻两个熔盐储箱1之间熔盐的流动速度时，可增加相邻两个熔盐储箱1之间的溢流管的数量。例如，每个熔盐储箱1的溢流口11和熔盐进口12均为4个，第一侧板14、第二侧板15、第三侧板16和第四侧板17中的每一者均设有一个溢流口11和熔盐进口12，相邻两个熔盐储箱1之间设有两个溢流管2以便提高溢流速度。
如图1所示，在一些实施例中，多个溢流管2包括多个第一溢流管21和多个第二溢流管22，多个第一溢流管21设在多个熔盐储箱1的一侧，多个第二溢流管22设在多个熔盐储箱1的另一侧，且多个第一溢流管21和多个第二溢流管22沿着熔盐的流动方向一一交替排布。也就是说，在熔盐的流动方向上，多个溢流管2交替设置在熔盐储箱1的边侧，从而可使得溢流管2不会相互影响。例如，在熔盐的流动方向上，第一个溢流管2(第一溢流管21)设在熔盐储箱1的右侧，第二个溢流管2(第二溢流管22)可设在熔盐储箱1的左侧，第三个溢流管2(第一溢流管21)可设在熔盐储箱1的右侧或前后侧。左右方向和前后方向如图1和图2中的箭头所示。
在一些实施例中，循环管3的进口31与对应的熔盐储箱1的溢流口11可拆卸地相连，循环管3的出口32与对应的熔盐储箱1的熔盐进口12可拆卸地相连。由此，在需要对熔盐储热装置100的熔盐储量进行扩增时，可在原有的多个熔盐储箱1的上方和下方增加熔盐储箱1后，使得循环管3的进口31与增加后的多个熔盐储箱1中位于最下方一者的溢流口11相连，循环管3的出口32与增加后的多个熔盐储箱1中位于最上方一者的熔盐进口12相连。。具体地，在原有的多个熔盐储箱1的上方新增有熔盐储箱1时，循环管3的出口32与增加后的位于最上方的熔盐储箱1相连，在原有的多个熔盐储箱1的下方新增有熔 盐储箱1时，循环管3的进口31与增加后的位于最下方的熔盐储箱1相连。
如图2和图3所示，根据本公开实施例的熔盐储热装置100包括分流器6，分流器6设在熔盐储箱1内的底部，分流器6具有分流腔以及多个与分流腔连通的分流孔63，分流孔63开设在分流器6的顶部，分流器6的进口构成熔盐储箱1的熔盐进口12。由此，可使得进入熔盐首先进入分流器6的分流腔内，然后通过多个与分流腔连通的分流孔63与熔盐储箱1内的熔盐换热，多个与分流腔连通的分流孔63可使得熔盐换热更加均匀，以便提高换热效率。
在一些实施例中，分流器6包括多个第一分流管61和多个第二分流管62，多个第一分流管61和多个第二分流管62中的每一者设有分流孔63。多个第一分流管61沿着熔盐储箱1的长度方向并行间隔排布，多个第二分流管62沿着熔盐储箱1的宽度方向并行间隔排布，每个第一分流管61均与多个第二分流管62连通。由此可使得熔盐通过多个第一分流管61和多个第二分流管62的顶部的分流孔63均匀地与熔盐储箱1内的熔盐换热。
在一些实施例中，至少部分第一分流管61的端部延伸至熔盐储箱1的外侧并形成熔盐进口12，至少部分第二分流管62的端部延伸至熔盐储箱1的外侧并形成熔盐进口12。从而便于熔盐进入分流器6(第一分流管61和第二分流管62)内。例如，多个第一分流管61和多个第二分流管62设在底板13上，多个第一分流管61沿着左右方向并行间隔排布，多个第二分流管62沿着前后方向并行间隔排布，位于中间的一个第一分流管61的两个端部延伸至熔盐储箱1(第二侧板15和第四侧板17)的外侧并形成熔盐进口12，位于中间位置的一个第二分流管62的两个端部延伸至熔盐储箱1的外侧(第一侧板14和第三侧板16)并形成熔盐进口12。
如图1所示，在一个具体地实施例中，多个熔盐储箱1包括由下至上依次设置的第一熔盐储箱101，第二熔盐储箱102，第三熔盐储箱103，第四熔盐储箱104。循环管3的进口31与第一熔盐储箱101的溢流口11相连，循环管3的出口32与第四熔盐储箱104的熔盐进口12相连。从而可使得第一熔盐储箱101内的熔盐在循环泵5的作用下进入循环管3内并与换热器换热后输送至第四熔盐储箱104内进行换热。
蓄热时，低温熔盐由第一熔盐储箱101的溢流接口8流出，在循环泵5的作用下，循环管3内的熔盐可与换热器4吸热升温。之后，高温熔盐由循环管3引入第四熔盐储箱104的熔盐进口12，高温熔盐进入第四熔盐储箱104的分流器6后，由分流孔63均匀流出，在第四熔盐储箱104的内形成由下到上、温度由高到低的温度分层，且高温区逐渐上移。当高温熔盐由第四熔盐储箱104上的溢流接口8流出后，受重力作用经溢流管2流入第三熔盐储箱103的熔盐进口12，并再次经历上述第四熔盐储箱104中的换热、流动过程。直至多个熔盐储箱1的第一熔盐储箱101中全部熔盐温度达标即完成蓄热过程。
释热时，高温熔盐由第一熔盐储箱101的溢流口11流出，在循环泵5的作用下，循环管3内的熔盐可与换热器4放热降温。之后，低温熔盐由循环管3引入第四熔盐储箱104的熔盐进口12，低温熔盐进入第四熔盐储箱104的分流器6后，由分流孔63均匀流出，在D层敞口熔盐储箱1内形成由下到上、温度由低到高的温度分层，且低温区逐渐上移。当低温熔盐由第四熔盐储箱104的溢流口11流出后，受重力作用经溢流管2流入第三熔盐储箱103的熔盐进口12，并再次经历上述第四熔盐储箱104中的换热、流动过程。直至多个熔盐储箱1的第一熔盐储箱101中全部熔盐降温至目标值即完成释热过程。
本公开的实施例还提出了一种熔盐储热系统，包括根据本公开实施例的熔盐储热装置100。
