▎ 摘　　要

NOVELTY - The tank has a tank main body provided with an outer tank and an inner tank. The outer tank is arranged on a base. A top part of the tank main body is formed with a first air outlet. The base is formed with a second air outlet that is connected with the tank main body. A support saddle is fixed on an inner wall of the outer tank. The inner tank is installed at an inner part of the outer tank. A hollow middle layer is formed between the outer tank and the inner tank. The hollow intermediate layer is filled with a silicon dioxide aerogel layer, where the inner tank is made of 06Ni9DR steel. The outer tank is formed with a graphene oxide reinforced concrete structure that is doped with 0.03% to 0.06% of oxidized graphene. USE - Liquefied natural gas storage tank. ADVANTAGE - The graphene oxide reinforced concrete structure has high strength, high electrical conductivity and high thermal conductivity so as to improve strength, durability and bearing capacity of the outer tank. The hollow intermediate layer is filled with the silicon dioxide aerogel layer with low density, high porosity, low thermal conductivity and low refractive index so as to reduce weight of the tank main body with better fireproof effect. The tank is environment-friendly, and has high-effective heat insulation material. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a liquefied natural gas storage tank.
