Example Embodiment
[0024] Example 1
[0025] Such as figure 1 As shown, the material of the thermal insulation layer 2 is a 5 cm thick aluminum silicate fiber blanket, and the strapping method is used for construction on the storage tank 1, and the strapping distance is 20 cm. The structure of the thermal insulation layer 2 has a 10mm circumferential expansion joint, which is filled with aluminum silicate fiber. The thermal insulation layer 2 is laid by multiple layers, staggered seams in the same layer, and laminated layers with inner and outer seams. The surface of each layer is leveled and tightly seamed.
[0026] The material of the reflective layer 3 is a 0.05mm thick smooth aluminum foil, which adopts a high-temperature adhesive and is evenly pasted on the surface of the insulating layer 2.
[0027] 100mm away from the outside of the reflective layer 3, with the center of the tank as the center, set 40×40×3mm angle steel evenly and vertically according to 30°, and then weld the first steel band ...
Example Embodiment
[0029] Example 2
[0030] Such as figure 2 As shown, the material of the thermal insulation layer 2 is 1 cm thick silica aerogel, which is constructed by the strapping method, and the strapping distance is 20 cm. The thermal insulation layer structure has a 10mm circumferential expansion joint, which is filled with aerogel fibers. The thermal insulation layer is laid in multiple layers, staggered seams in the same layer, and laminated layers inside and outside, and tied layer by layer, and the surface of each layer is leveled and tightly seamed.
[0031] The material of the reflective layer 3 is a 0.05mm thick glossy stainless steel foil, using a high-temperature adhesive, and evenly pasted on the surface of the aerogel in advance, and set in the middle of the thermal insulation layer.
[0032] 100mm away from the outer side of the thermal insulation layer, with the center of the tank as the center, set 40×40×3mm angle steel uniformly and vertically according to 45°, and then weld...
