The fused salt storage tank of this embodiment, its main structure layer 2 is used for bearing mechanical stress, wearing layer 5 is used for bearing thermal stress, the expansion gap 10 of wearing layer 5 configuration is in order to eliminate high temperature thermal stress heating expansion, and give main structure layer 2 with static pressure, thermal stress transmission through adiabatic connecting piece 4, thereby reduced main structure layer 2, wearing layer 5 demand to the material, need not use expensive nickel base alloy in order to reach the heat-retaining demand, reduced the cost of fused salt storage tank.

Wherein, wearing layer 5 has partial stress to transmit for main structure layer 2 through second heat preservation 3 when expansion deformation, therefore second heat preservation 3 still need to have certain structural strength when having better heat preservation performance, and compressive strength needs to be higher than 10MPa usually, can adopt nanometer insulation material. The temperature of the outer wall of the second insulating layer 3 is not higher than 400 ℃, the main structure layer 2 still has good strength below 400 ℃, and can be made of carbon steel materials, and the heat insulation connecting piece 4 is made of materials with high strength and low heat conductivity coefficient.
In some embodiments, the wear layer 5 comprises a plurality of wear units, at least one of which is fixed to the primary structural layer 2 by an insulating joint 4, wherein the expansion gaps 10 are arranged between adjacent wear units.
In some embodiments, the wear layer 5 comprises a plurality of wear units, each of which is fixed to the main structure layer 2 by a thermal insulation connector 4, wherein the expansion gaps 10 are disposed between adjacent wear units.

The wear-resistant unit close to the bottom of the tank body bears larger static pressure, so that the expansion gap 10 is ensured to be gradually closed along with the increase of the height of the particles, and the particles are prevented from blocking the expansion gap 10. The expansion gap 10 is designed such that its thickness t is not greater than the minimum particle diameter of the particles.

In some embodiments, the bottom 7 of the molten salt storage tank is constructed in a conical structure, so that impact loss caused by falling of unloading particles on the top of the tank can be reduced, and the storage tank can be effectively emptied. Wherein, jar body bottom 7 includes firebrick layer 72 and storage tank diapire 71, and firebrick layer 72 structure is the toper structure, has both had the heat preservation function, also can regard as storage tank bottom basis to bear the load, and storage tank diapire 71 is fixed in firebrick layer 72 top.

The tank top 6 comprises a tank top inner wall 61 and a third insulating layer 62, and the third insulating layer 62 is fixed above the tank top inner wall 61. The third insulating layer 62 can be made of high-performance light insulating materials to reduce the weight of the tank top; the third insulating layer 62 may have a single-layer structure or a double-layer structure, and is not limited herein.
Further, the expansion gap 10 is arranged between the wear-resistant layer 5 and the tank bottom 7, and the expansion gap 10 is arranged between the wear-resistant layer 5 and the tank top 6.
