Description
Technical field
The invention belongs to liquefied natural gas (referred to as LNG) containment system, particularly a kind of film prismatic LNG of flat board half is gone along with sb. to guard him
System.
Background technology
LNG containment systems at present, the self-supporting of mill heavy industry (IHI) exploitation is particularly the most similarly broadcast by Japanese Ishikawa island
Formula prismatic Type B (SPB) containment system.The containment system inside cabin is formed by stainless steel or Welded, set in cabin swash bulkhead,
Stiffener and horizontal side plate, it can effectively eliminate rocking for internal liquid.Wrapped up outside nacelle by prefabricated polyurethane heat insulation.
Inside cabin is supported with hull by the support block being fixed on hull.Pass through the wedge-shaped slot on a chock and hull at the top of inside cabin
Carry out spacing, prevent inside cabin from belowdecks moving.Gap is left between inside cabin and hull, convenient to check inside cabin, bottom is covered with secondary
Shielding, for accepting the LNG flowed out when inside cabin leaks.
The maximum advantage of self supporting type prismatic Type B containment system is by setting some structures to eliminate internal liquid in cabin
Rock and make the loading of liquid goods unrestricted.But the volume in a part of cabin can be so sacrificed, inside cabin internal structure is complicated.
And it is spacing to inside cabin progress only by the chock at the top of inside cabin, inside cabin and hull can be caused in this position stress concentration.
The content of the invention
It is an object of the invention to overcome above-mentioned prior art deficiency, there is provided a kind of film prismatic LNG containment systems of flat board half,
Described flat board refers to that its inside cabin tank is welded by the regular aluminum of shape or steel plateform, and half film refers to its containment system
Secondary shielding only needs portion envelops without with fully wrapped around inside cabin tank, and prismatic refers to the containment system monnolithic case to be regular similar
In prismatic polygon column structure, the containment system have plot ratio is bigger, weight is lighter, the influence to Ship Structure more
The advantages of small.
The technical solution of the present invention is as follows：
A kind of film prismatic LNG containment systems of flat board half, its feature be to include inside cabin tank, thermal insulation layer, outside steel frame and
Common support thing, the inside of described inside cabin tank only have the stiffener of support housing, and described inside cabin tank outer wrapping is complete described
Directly it is landed in after thermal insulation layer in the secondary shielding in hull, described steel frame forms the part in described hull, described
Inside cabin tank top and surrounding be connected by common support thing with described steel frame, described common support thing has longitudinal shifting
Dynamic, transverse shifting and rotate 3 frees degree around own axes.
Described inside cabin tank is by aluminium alloy or nickel steel welding manufacture.
The material of described thermal insulation layer is polyurethane.
The material of described steel frame is identical with the construction material of hull.
Construction, installation, insulation and the test of the described film prismatic LNG containment systems of flat board half are carried out outside hull,
Entirety hangs in hull and assembled afterwards.
A kind of patented common support thing that connects through of steelframe and the inside cabin tank of aluminum (refers to patent
US7896188B2,2011.05.01；US8430263B2,2013.04.30；CN101674976B, 2013.11.20) realize, permit
Perhaps the expansion of inside cabin tank, shrink, while by liquid and rock load and be transferred directly to Ship Structure, maintenance system is not loaded limit
System, will not also be influenceed by rocking.
The technique effect of the present invention is as follows：
The inside cabin tank of the film prismatic LNG containment systems of flat board half of the present invention is flexible tank, and the inside only support of inside cabin tank is outer
The stiffener of shell, no supernumerary structure, compared with existing SPB types LNG containment systems, the structure of inside cabin tank is simpler, expends
Man-hour is less, and weight is lighter, and internal capacity rate is bigger.
Existing SPB types LNG containment systems merely by the chock at top come to containment system carry out it is spacing, severe
Stress concentration is easily formed to corresponding hull position in the case of sea situation, and LNG containment systems of the present invention are by inside cabin tank
The equally distributed common support thing of surrounding carrys out spacing and fixed containment system, and described common support thing vertically moves, be horizontal
3 frees degree are rotated to movement and around own axes.This device can fully absorb liquid goods and rock caused impact.Load
Distribution is more uniform, is influenceed to caused by the structure of hull smaller.
LNG containment systems of the present invention, have that plot ratio is bigger, weight is lighter and that influence to Ship Structure is smaller is excellent
Point.
