Description
Technical Field
The invention relates to the technical field of equipment for transporting and storing low-temperature liquid, in particular to a three-face corner area arrangement structure of a film type enclosure system.
Background
In transporting a gas such as natural gas or ethane gas, it is common to cool the gas to a low temperature and transport the liquefied gas for more economical long-distance transportation. The volume of the liquefied gas is greatly reduced, and the transportation cost is reduced. The liquefied cryogenic liquid is stored and transported by a special cryogenic liquid cargo storage tank.
In the current shipbuilding industry, cryogenic liquid cargo containment systems are primarily concerned with the manufacturing of LNG vessels. For LNG vessels, the international bulk transport liquefied gas vessel construction and equipment regulations (IGC regulations) define 4 broad classes of containment systems, type a, type B, type C and thin film containment systems, respectively. The thin film type enclosure system is widely applied due to the advantages of high cabin capacity utilization rate, good heat preservation performance, small wind resistance area and the like.
The existing thin film containment system technology mainly comprises Mark III type and NO 96 type, which are both from French GTT company. However, for the NO 96 type, as the main insulating modules and the secondary insulating modules are overlapped up and down, gaps between the main insulating modules and gaps between the secondary insulating modules are directly communicated to the ship body structure, and heat insulation materials such as glass wool are uniformly distributed at the gaps, but larger heat leakage exists at the gaps; for Mark III type, as the main layer insulating module, the secondary layer insulating module and the secondary layer film are mutually fixed and adhered into a whole through glue, and are fixed on the ship body structure through epoxy resin, the relative movement between the main layer insulating module and the secondary layer insulating module is limited, and the whole ship body movement resistance and liquid cargo sloshing resistance are poor; in addition, due to the fact that a large amount of glue is used, the construction period is long, and due to the fact that requirements on construction environment (humidity and temperature) and working procedures are strict, the period of the ship is prolonged.
