Problems solved by technology

When the low-temperature medium in the inner tank leaks, the hot corner protection structure will shrink greatly under the influence of the low-temperature medium, which will cause very large temperature difference stress

Example Embodiment

[0022] Example

[0023] A double thermal angle protection structure, such as Figure 1 ~ Figure 2 As shown, it is arranged between the inner and outer tanks 1 of the low-temperature storage tank, and includes an upper thermal corner structure and a lower thermal corner structure 12;

[0024] The upper thermal corner structure includes the thermal corner protective wall plate 2, the lower edge plate 13, the upper sliding bottom plate 11, the edge baffle 16 and the flexible sealing layer 15 with a uniform ring tank body design; the lower edge plate 13 is flat, and the thermal corner is protected The wall plate 2 is erected on one end of the lower edge plate 13 close to the outer tank 1. The thermal corner protection wall plate 2 and the lower edge plate 13 are preferably connected by a fixed method such as welding at 90°; the upper sliding bottom plate 11 is laid on the edge of the lower layer The board 13 can be slid freely. Specifically, the upper sliding bottom plate 11 is connected

Abstract

The invention discloses a double hot corner protection structure. The protection structure is arranged between an inner tank and an outer tank of a low-temperature storage tank and comprises an upperhot corner structure and a lower hot corner structure, wherein the upper hot corner structure has excellent elastic shrinkage performance, can guarantee good sealing performance and is not easily damaged, and when a medium in the inner tank leaks and the upper hot corner structure is damaged, the lower hot corner structure is used for bearing low-temperature impact of the leaked medium and is notdamaged, so that double protection at the joint of the tank wall and the tank bottom of the outer tank is realized. The invention further discloses the low-temperature storage tank. A bottom plate ofthe hot corner protection structure is arranged at the lower part of a concrete ring wall, the temperature borne by the bottom plate of the hot corner protection structure under the normal operating condition is increased to some extent, the low-temperature shrinkage amount of the bottom plate under the normal operating condition is reduced, meanwhile, the consumption of the lower hot corner structure is reduced, and the cost is saved; and the low-temperature storage tank solves the problem of low-temperature shrinkage of the hot corner protection structure and has excellent safety and stability.
