Embodiment approach

[0030] As a preferred embodiment of the present invention, the surface of the embedded metal plate 2 is welded with an insulating plate to fix studs 4, and the studs are selected from M8-M16, and each embedded metal plate 2 is welded with 6-12 studs for Fix the thermal insulation board 5.

[0031] As a preferred embodiment of the present invention, the back of the thermal insulation board 5 is leveled with the concrete outer tank and the bottom plate 1 by coating resin glue, and the coating thickness of the resin glue is 3-50mm.

[0032] As a preferred embodiment of the present invention, the said pre-embedded metal plate 2 should undergo a corresponding tensile test in the concrete outer tank and the bottom plate 1 .

[0033] As a preferred embodiment of the present invention, the insulating plate fixing stud 4 is fixed on the embedded metal plate 2 by resistance welding or manual welding, and the fixing method should be subjected to a corresponding tensile test.

[0034] Th...

Embodiment 1

[0037] Concrete outer tank and bottom plate 1 need to build construction platform scaffolding design: in the process of construction, it is necessary to design a complete set of modular scaffolding, and provide corresponding working platforms and storage platforms, and the strength and safety performance of the design are balanced. Specification requirements must be met.

[0038]Before pouring the concrete outer tank and the bottom plate 1, it is necessary to fix the pre-embedded metal plate 2, fix it in the concrete steel skeleton, fix the anchor bolt 3 on one side of the concrete, and make sure that the side of the plate is flush with the inner wall of the tank. The levelness and verticality meet certain requirements, and the allowable deviation of the basic positioning cannot exceed ±20mm. After the measurement and inspection, the pouring of the outer concrete tank and the bottom plate can be carried out.

Embodiment 2

[0040] The installation of the moisture-proof isolation layer 6: in consideration of keeping the interlayer airtight, preventing gas outside the tank from entering the space of the insulation layer of the inner tank, and at the same time, after LNG leaks into the insulation layer of the inner tank of the film, it can isolate and prevent it from leaking to the outside through the concrete, It is necessary to install the moisture-proof isolation layer 6 after the concrete outer tank and the inner wall of the bottom plate 1 are completed. Considering the airtightness of the embedded metal plate 2, the concrete outer tank and the inner wall of the bottom plate 1, the coating of the moisture-proof isolation layer should be carried out after the fixing studs 4 are installed.

[0041] The moisture-proof isolation layer 6 can be sprayed with epoxy glue, and an adhesion test is required to ensure that the glue is complete and does not fall off, and has reliable airtightness. Or you can...

Abstract

The invention discloses a fixed installation mode of an insulating plate of a low-temperature thin-film land storage tank for liquefied natural gas storage. A concrete outer tank and bottom plate, an embedded metal plate, anchor bolts, insulating plate fixing studs, a heat preservation insulating plate and a damp-proof isolation layer are included. The embedded metal plate is pre-laid and installed during the construction period of the concrete outer tank and bottom plate, the damp-proof isolation layer is installed on the inner surface of the concrete outer tank and bottom plate, the insulating plate fixing studs are installed on the embedded metal plate through a resistance welding machine, and the back face of the heat preservation insulating plate is coated with resin glue; and the heat preservation insulating plate is fixedly arranged on the inner wall of the concrete outer tank and bottom plate through the insulating plate fixing studs. The installation mode that expansion bolts are installed by drilling holes in the concrete and a bottom plate is replaced, the safety of the low-temperature thin-film storage tank is improved through the design, the construction workload is reduced, the construction period is shortened, the equipment safety is improved, and the concept of green and environmental protection can be achieved.

Description

technical field [0001] The invention relates to the technical field of liquefied natural gas (LNG) low-temperature storage devices, in particular to a fixed installation method for an insulating plate of a low-temperature thin-film land storage tank used for storage of liquefied natural gas. Background technique [0002] Liquefied natural gas (LNG) has always been the preferred energy source for oil replacement due to its advantages of greenness, environmental protection and high efficiency, and has become one of the fastest-growing energy industries in the world. With the rapid development of my country's economy and the continuous improvement of environmental governance requirements, the application and development of LNG has attracted more and more attention from all parties, especially in the case of frequent haze weather, the importance of LNG has become increasingly prominent. This has led to the rapid growth of society's demand for clean energy. One of the key directi...
