With the continuous acceleration of the urbanization process in China, the urban scale is gradually enlarged, the urban population is continuously increased, and the urban safety problem brought in succession is increasingly prominent. The large-scale storage tank generally stores liquid oxygen, liquid argon, liquid nitrogen, liquid carbon dioxide or liquefied natural gas, belongs to important city life line engineering, and has the advantages of obvious difference in structural form compared with common storage tank facilities, complex structural design and higher safety level requirement.
At present, the design specifications of the super-huge LNG storage tank require the design of impact resistance and explosion resistance on the structure, but the outer concrete tank body is mainly used as a main protective body, so that the super-huge LNG storage tank is unsafe under the action of actual extreme load. Meanwhile, the single-layer tank body is extremely difficult to repair after being damaged, so that huge investment waste can be caused.
For the above reasons, referring to fig. 1 and 2, fig. 1 and 2 show the structure of a storage tank in an embodiment of the present invention, and this embodiment provides a storage tank 200, in which the storage tank 200 can reduce the influence of external impact or explosion and other loads on the inside, and can reduce the influence and diffusion of internal leakage, fire or explosion and other accidents on the outside, so as to reduce the repair cost, and the storage tank 200 includes a tank body 210 and a protective structure 220;
the protective structure 220 is wrapped outside the tank 210, and includes a first protective concrete layer 221, a buffer layer 222 and a second protective concrete layer 223 sequentially arranged from the inside of the tank 210 to the outside of the tank 210.
The working principle of the storage tank 200 is as follows:
the storage tank 200 includes a tank body 210 and a shielding structure 220. The protective structure 220 is wrapped outside the tank 210, and includes a first protective concrete layer 221, a buffer layer 222, and a second protective concrete layer 223 sequentially arranged from inside the tank 210 to outside the tank 210. Due to the arrangement of the tank body 210 and the protective structure 220, the external load and the internal storage pressure are relatively independent, and the protective structure 220 can bear the external load, particularly resist external impact, so as to protect the internal tank body 210. In addition, due to the arrangement mode, the tank body 210 is not impacted from the outside, and in the process of bearing the load, the protective structure 220 plays a role in bearing the load, so even if the protective structure 220 is damaged by the load, the normal work of the tank body 210 is not influenced, and the repairing cost of the storage tank 200 can be reduced. Meanwhile, when accidents such as leakage, fire or explosion happen inside the device, the device can be guaranteed not to influence and diffuse outside. In addition, in the arrangement mode, since the tank 210 is used for bearing the internal storage pressure without bearing the external impact load, and the protection structure 220 is also not required for bearing the internal pressure, the thickness of the tank 210 can be reduced on the premise of meeting the use requirement when the tank 210 is arranged, thereby being beneficial to reducing the manufacturing cost of the storage tank 200.
