Bimetal low-temperature film storage cabin for storing liquefied natural gas

Abstract

The invention discloses a bimetal low-temperature film storage cabin for storing liquefied natural gas. Metal film plates are used for replacing existing films, the dependence on the films of specialequipment is reduced, global supply is achieved, the metal film plates are used for replacing the existing films, the application of low-temperature-resistant glue in field construction is reduced, alarge number of workshop pre-insulating plates are greatly used, the field workload is reduced, and the construction progress is accelerated. Besides, generally mature automatic welding and manual welding work is adopted for the metal film plates, so that the workload is reduced, the safety of the low-temperature film storage cabin is improved, the limitation of the cargo cabin on free liquid level loading of liquid cargoes is reduced, and the application and time consumption of the low-temperature-resistant glue in the construction process are reduced; and a mature and safe bimetal film platewelding design manner and an environment-friendly manner of prefabricating foaming insulation panels in advance are adopted, so that the construction workload is reduced, the construction period is shortened, the equipment safety is improved, and the concept of 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 bimetal low-temperature thin-film storage cabin for storing liquefied natural gas. Background technique [0002] Liquefied natural gas (LNG) has always been the preferred energy alternative to petroleum 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. Since the methane pioneer METHANEPIONEEER began its test operation in 1959, the wor...

Problems solved by technology

[0005] The present invention provides a bimetallic low-temperature thin-film storage cabin for storage of liquefied natural gas, which solves the problem that the prior art has a relatively high dependence on the original storage cabin thin-film form, and the manufacturing cost of the thin-film is relatively high and the supply is extremely limited. There is a large amount of work on site, and the amount of glue used is relatively large. The secondary insulating layers are all glued together, and the safety performance is poor. The butt joint of the main shielding film and the welding of the main shielding layer all consume a lot of man-hours. question
