Abstract

The application discloses novel low temperature storage tank glass steel outer jacket composite construction follows low temperature storage tank surface by supreme heat preservation, composite bed and the glass steel outer jacket of including in proper order down, the heat preservation is formed by polyurethane foam, the composite bed comprises frivolous leakproofness material. The utility model provides a novel low temperature storage tank glass steel outer jacket composite construction satisfies under the glass steel outer jacket function, and the relative independent shrink of low temperature jar body soft heat preservation and stereoplasm glass steel outer jacket avoids extrusion fracture, heat preservation inefficacy. The composite layer can also continuously maintain the steam shielding function after the surface layer glass fiber reinforced plastic cracks, reduce the maintenance frequency and delay the maintenance period.

Description

Novel low temperature storage tank glass steel outer jacket composite construction

Technical Field

The utility model relates to a novel low temperature storage tank glass steel outer jacket composite construction, this structure are applicable to and adopt glass steel as cryogenic liquid cargo hold heat preservation outer jacket field, have higher requirement to the fracture and the later stage non-maintaining that the low temperature jar body/heat preservation/outer jacket shrinkage ratio inconsistent brought.

Background

In the prior art, the ultra-low temperature cryogenic liquid cargo tank usually adopts polyurethane, polyisocyanate, polystyrene and the like as heat insulation materials to control the temperature and the pressure of liquid cargo in the tank. The heat insulation material is soft, can not isolate water vapor and sunlight radiation for a long time, and can not meet severe working conditions at sea. Therefore, a special glass fiber reinforced plastic outer protective layer is arranged outside the heat-insulating layer, and the requirements of mechanical performance and steam shielding performance are met.

At present, a glass fiber reinforced plastic outer protection layer adopted by the low-temperature liquefaction tank cabin heat preservation is directly arranged on the heat preservation surface of the liquid cargo cabin in a hand brushing or spraying mode. After the glass fiber reinforced plastic is cured, the glass fiber reinforced plastic and the soft insulating layer are tightly combined because the resin is adhered. After the low-temperature liquid cargo is filled, certain tank body shrinkage deformation can be caused, the shrinkage ratios of the tank body steel, the soft heat insulation layer and the hard glass fiber reinforced plastic outer protection layer are inconsistent, and the heat insulation layer drives the glass fiber reinforced plastic to shrink, extrude, deform and even crack, so that the phenomenon of heat insulation failure occurs.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel low temperature storage tank glass steel outer jacket composite construction to overcome not enough among the prior art.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a novel low temperature storage tank glass steel outer jacket composite construction, includes heat preservation, composite bed and glass steel outer jacket along the low temperature storage tank surface by supreme down in proper order, the heat preservation is formed by polyurethane foam, the composite bed comprises frivolous leakproofness material.

Preferably, the composite layer is a thin mastic layer.

Preferably, the composite layer is a plastic film.

Preferably, the composite layer is an aluminum foil.

Preferably, the composite layer is aluminum foil fiberglass cloth.

Compared with the prior art, the novel low-temperature storage tank glass fiber reinforced plastic outer protection layer composite structure has the advantages that the low-temperature tank body/soft heat insulation layer and the hard glass fiber reinforced plastic outer protection layer contract relatively and independently under the condition that the function of the glass fiber reinforced plastic outer protection layer is met, and extrusion cracking and heat insulation failure are avoided. The composite layer can also continuously maintain the steam shielding function after the surface layer glass fiber reinforced plastic cracks, reduce the maintenance frequency and delay the maintenance period.
