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

Storage tank with pliable and tough bottom
Preamble according to claim can be known, the present invention relates to a kind of application low temperature storage tank aboard ship.
Low temperature storage tank has very exacting requirements for leakage.If storage tank receives the influence of live load, leakage will produce, and the tension force that produces also can cause the material production crackle of storage tank.Live load possibly also possibly produce owing to the dynamic deflection of supporting construction because the direct load on the storage tank produces.Low temperature storage tank is because bigger temperature traverse also is easy to generate great deflection, and these problems should solve to avoid on storage tank, producing high load capacity as much as possible.Utilize as far as possible to greatest extent effective volume with suitable storage tank subregion is set in case subsequent use with safeguard it also is very important, therefore when design storage tanks, must consider these problems.Sometimes, it also is very important that the zone above the storage tank can be utilized, that is, storage tank should be installed in the for example below on deck through equipment as much as possible.
There is the low temperature storage tank of a lot of types to solve above-mentioned most defective and deficiency now through different tank design and support.
According to the characteristic described in the 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.
The support of storage tank can absorb a small amount of live load that produces on the storage tank among the present invention, and has reached deflection and because the effective ways of the deflection that temperature traverse produces on a kind of absorptive substrate.And the storage tank subregion through suitable can well utilize effective volume, has also provided the possibility that storage facilities is set on the deck on storage tank top in the technical scheme of the present invention.
Storage tank of the present invention comprises the cylindrical tank skin 1 and horizontal base 2 of vertical setting, and cylindrical tank skin 1 has top board 7.Storage tank is supported by the cylindrical skirt 9 that is arranged between storage tank top board 7 and the 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 with transverse force from storage tank, and annular or polygon skirt section 4 are delivered to infrabasal plate 5 with transverse force again.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 then is delivered to ring-shaped skirt 4 through gimbal 3.
If necessary, the bracket 11 that radially is provided with can be installed by the crossover position place between the horizontal base 2 of the cylindrical tank skin 1 of storage tank and storage tank.The transmission that bracket 11 can be designed to from cylindrical tank skin 1 to the power of horizontal base 2 provides a buffering.Support 12 on bracket 11 and the cylindrical tank skin 1 links to each other with the support 13 on the horizontal base 2.
In addition, gimbal 3 is provided with ring-shaped skirt 14, and ring-shaped skirt 14 has constituted the device of collecting the cryogenic liquid that possibly reveal from storage tank.A material layer 15 also can be set 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 last isolation layer 6, and skirt section 8 has constituted second device of collecting the cryogenic liquid that possibly reveal.
Vertical type low temperature storage tank among the present invention has cylindrical outer shape, can not only effectively utilize self capacity of storage tank, can also utilize effective volume fully.

Claims (3)

1. one kind with aboard ship low temperature storage tank, storage tank be arranged between two substrates or deck (5,10) and with two substrates or deck (5; 10) connect, it is characterized in that storage tank comprises a horizontal base (2); Horizontal base (2) links to each other with cylindrical tank skin (1); Base (2) extends out to annular or polygon skirt section (4) from the tank skin (1) with gimbal (3), and annular or polygon skirt section (4) link to each other with infrabasal plate (5), and base (2) is arranged on the 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, and 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 last isolation layer (6).
3. storage tank according to claim 1 is characterized in that, with the contacted bracket of support (12,13) (11) horizontal base (2) and tank skin (1) is linked together.
