Abstract

A cryogenic tank for a vessel is disclosed, wherein the tank is placed between and connected with two decks or fundaments (5, 10). The tank that comprises a horizontal base (2) to which a cylindrical wall (1) is connected. The base (2) ranges outside the wall (1) with a horizontal ring (3) to a circular or polygonal skirt (4) which is connected to the lower fundament (5). The base (2) rests on insulation (6) that carry load.

Description

There is the storage tank of flexible lower portion
Known according to the preamble of claim, the present invention relates to a kind of application low temperature storage tank aboard ship.
Low temperature storage tank has very strict requirement for leakage.If storage tank is subject to the impact of live load, leakage will produce, and the tension force producing also can cause the material production crackle of storage tank.Live load may produce due to the direct load on storage tank, also may be because the dynamic deflection of supporting construction produces.Low temperature storage tank is because larger temperature traverse also easily produces great deflection, and these problems should solve to avoid to produce on storage tank high load capacity as much as possible.Utilize as far as possible to greatest extent effective volume and suitable storage tank subregion is set so as for subsequent use and safeguard be also very important, therefore in the time of design storage tanks, must consider these problems.Sometimes, it is also very important that the region above storage tank can be utilized, that is, storage tank should be arranged on the below on for example deck as much as possible by equipment.
There is now very eurypalynous low temperature storage tank to solve above-mentioned most defect and deficiency by different tank design and support.
According to the feature described in claim, storage tank of the present invention has been realized above-mentioned purpose.
Fig. 1 is the longitudinal diagram of low temperature storage tank of the present invention, and Fig. 2 is the detail drawing of storage tank column part and storage tank planar base connection location.
In the present invention, the support of storage tank can absorb a small amount of live load producing on storage tank, and has reached deflection and because the effective ways of the deflection that temperature traverse produces in a kind of absorptive substrate.And, by suitable storage tank subregion, can well utilize effective volume, in technical scheme of the present invention, also provide the possibility that storage facilities is set on the deck on storage tank top.
Storage tank of the present invention comprises cylindrical tank skin 1 and the horizontal base 2 of vertical setting, and cylindrical tank skin 1 has top board 7.Storage tank is supported by the cylindrical skirt 9 being arranged between storage tank top board 7 and upper substrate 10.
The bottom of storage tank is supported by load-bearing isolation layer 6, so that tank bottom is left infrabasal plate 5.6 transmission of load-bearing isolation layer are from the longitudinal force of storage tank.Gimbal 3 is delivered to annular or polygon skirt section 4 by transverse force from storage tank, and annular or polygon skirt section 4 are delivered to transverse force again infrabasal plate 5.Gimbal 3 in the vertical directions are soft, so that can on average be disperseed and be delivered to load-bearing isolation layer 6 from the longitudinal force of storage tank, transverse force is delivered to ring-shaped skirt 4 by gimbal 3.
If necessary, the bracket 11 radially arranging can be installed by the crossover position place between the cylindrical tank skin 1 of storage tank and the horizontal base 2 of storage tank.Bracket 11 can design to become provides a buffering from cylindrical tank skin 1 to the transmission of the power of horizontal base 2.Bracket 11 is connected with the support 13 on horizontal base 2 with the support 12 on cylindrical tank skin 1.
In addition, be provided with ring-shaped skirt 14 in gimbal 3, ring-shaped skirt 14 has formed the device of collecting the cryogenic liquid that may reveal from storage tank.A material layer 15 also can be set and accept the barrier of cryogenic liquid as other one deck, material layer 15 is arranged between two isolation layers, and material layer 15 extends outwardly into skirt section 8 from upper isolation layer 6, skirt section 8 has formed the second device of collecting the cryogenic liquid that may reveal.
Vertical type low temperature storage tank in the present invention, has cylindrical outer shape, can not only effectively utilize self capacity of storage tank, can also utilize fully effective volume.

Claims (3)

1. one kind with low temperature storage tank aboard ship, storage tank is arranged on two substrates (5, 10) between and with two substrates (5, 10) connect, described two substrates (5, 10) comprise upper substrate (10) and infrabasal plate (5), it is characterized in that, storage tank comprises a horizontal base (2), horizontal base (2) is connected with cylindrical tank skin (1), base (2) extends out to annular or polygon skirt section (4) from having the tank skin (1) of gimbal (3), annular or polygon skirt section (4) are connected with infrabasal plate (5), base (2) is arranged on load-bearing isolation layer (6).
2. storage tank according to claim 1, it is characterized in that, load-bearing isolation layer (6) comprises two flat seams that are stacked together, load-bearing isolation layer (6) has the intermediate layer of material (15) of accepting cryogenic liquid, and intermediate layer of material (15) extends out to skirt section (8) from upper isolation layer (6).
