Foundation structure for supporting high-temperature molten salt storage tank
The invention relates to the technical field of high-temperature heat storage, in particular to a foundation structure for supporting a high-temperature fused salt storage tank. The foundation structure comprises a concrete foundation layer, a ceramsite layer, a foam glass layer, a calcium silicate layer and a sand cushion layer which are sequentially stacked upwards from the ground. The sand cushion layer is used for making contact with the tank bottom of the high-temperature fused salt storage tank, receiving heat from the tank bottom of the high-temperature fused salt storage tank and conducting the heat downwards. The calcium silicate layer can keep the temperature of the foam glass layer to be lower than the temperature-resistant upper limit value when receiving heat transferred from the sand cushion layer. According to the foundation structure, the heat loss of the foundation structure in the ground direction can be reduced while the cost is not obviously increased, meanwhile, differential settlement is avoided, and the foundation structure is suitable for molten salt materials with the use temperature reaching 650 DEG C or above.
本发明涉及高温储热技术领域，尤其涉及一种用于支承高温熔盐储罐的基础结构。基础结构包括由地面向上依次叠置的砼基础层、陶粒层、泡沫玻璃层、硅酸钙层和砂土垫层。砂土垫层用于与高温熔盐储罐的罐底接触，接收来自高温熔盐储罐的罐底的热量并向下传导。硅酸钙层能够在其接收到砂土垫层传来的热量时，使泡沫玻璃层的温度保持在低于其耐温上限值。本发明的基础结构能够在不显著增加成本的同时，减少基础结构向地面方向的热损失，同时不会发生不均匀沉降，适用于使用温度达到650℃及以上的熔盐材料。
