Standard template for storage structure and liquefied natural gas storage structure

Abstract

The invention discloses a storage structure for storing liquefied natural gas and a standard template for forming a shielding film, the storage structure comprises a supporting plate, an insulating plate and the shielding film, the shielding film is made of the standard template, the supporting plate is connected with the insulating plate and the shielding film, the insulating plate is fixed on the supporting plate, and the insulating plate is formed by splicing a plurality of standard modules. An existing film is replaced with a steel film plate, dependence on a special equipment film is reduced, global supply is achieved, the working hours of glue bonding, waiting and drying on site are reduced, welding work familiar to a shipyard is changed, and the workload is reduced; and partial prefabrication can be performed before the ship is closed, so that the construction period is shortened.

Description

[0001] This application is a divisional application of an invention patent application with an application date of November 6, 2020, an application number of 202011229787.0, and a title of "a shielding device for metal cryogenic film tanks for storage of liquefied natural gas". technical field [0002] The present invention relates to the technical field of liquefied natural gas (LNG) cryogenic storage devices, in particular to a storage structure for storing liquefied natural gas. Background technique [0003] 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, especi...

Problems solved by technology

[0006] However, the existing storage tanks for storing liquefied natural gas have the following problems: (1) The existing technology relies heavily on the original storage tank film form, and the production cost of the film is relatively high and the supply is extremely limited , the workload of the existing technology site is relatively large, the amount of glue used is relatively large, the secondary insulating layers are all glued together, the safety performance is poor, and the butt joint of the main shielding film and the welding of the main shielding layer all consume a lot of man-hours; (2) The construction period of the existing technology is relatively long, and due to strict requirements on the construction environment (humidity and temperature) and process, the delivery date of the whole ship is delayed
