Description

Be used for device at ship supporting storage bin
Technical field
The present invention relates to a kind ofly be used for the particularly device of the independent storage bin of LNG of blue gas in ship supporting according to claim 1 as described in the preamble being used for, and a kind of double-valve type (bilobe) forbay that is particularly suitable for said apparatus.
Background technology
For in the ship seagoing ship transport liquefied gases of merely hitting particularly, multiple solution is arranged traditionally.All relate in all cases be used in low temperature or refrigerant fluid gasification container in ship with respect to ship shell thermal insulation, set up being connected of this container and ship shell simultaneously, the following acceleration/accel of 1.5g that this connection holds out against cargo-carring load and occurs under steam.Except that whole storage bin, thin metal storage bin and half thin metal storage bin (Semi-Membrantank), also use blue gas independence storage bin, this independent storage bin itself does not promptly rely on ship structure ground mechanically stable.Also have or not the branch of pressing case and forbay at this, wherein do not have and press the temperature of the blue gas in the case low especially naturally.
At this, liquefied natural gas (LNG) proposes special requirement to structure, because its temperature is lower than common technical blue gas.
Built the ship with the described types of devices of beginning that is used for transport liquefied gases, wherein storage bin is columnar, and with its longitudinal axis along ship vertically, once in a while also along laterally placing.At this, be fixed on the pedestal on the ship shell and be complementary with the cylindrical shape storage bin, roughly arc saddle forms structural unit, and thermal insulation layer is arranged between saddle and the storage bin.Be guaranteed not vertically move relatively on storage bin in two saddles, but on another saddle, can be along the longitudinal movement, thereby can not produce thermal stress in the vertical with respect to this saddle.Because store box-shaped sealed/form fit is arranged in saddle (formschl ü ssig), so this storage bin is maintained fixed transverse to end wise.But the point of the bottommost in the saddle appears in the thermal contraction on this direction, therefore very big thermal stress also do not occur with regard to this respect.
Very big thermal stress is inappropriate for so-called double-valve type storage bin, and this double-valve type storage bin has two parallel, shapes of incision cylinder wherein each other.This double-valve type storage bin has used a period of time, because it has more effectively utilized boat space than cylindrical shape storage bin, has kept the advantage aspect mechanical stability simultaneously.For supporting double-valve type storage bin in ship, used the device aforementioned structure mode, that have the common saddle that is used for two storage bin halfbodies.Corresponding to the storage bin shape, these saddles have two along laterally interconnective arc design of storage bin.Here, thermal contraction in the horizontal occurs on the saddle vertex in the middle of saddle, and the result produces thermal stress.If the higher relatively blue gas of boiling point ethene (-100 ℃ approximately of gas-filling temperatures) for example, this can also accept.As the lower temperature that in liquefied natural gas, is occurred under, described known structure is restricted, or rather because the temperature of self and additionally because the big thermal expansion coefficient of the storage bin material that must use for the refrigerant fluid gasification.
Summary of the invention
The objective of the invention is to, create a kind of device that starts described type, this device not only is suitable for columnar, and is suitable for the double-valve type storage bin, and described storage bin should be loaded particularly LNG of blue gas low temperature, that what is called is freezing.
According to the present invention, above-mentioned purpose realizes that by the device of describing its feature with claim 1 wherein preferred embodiment is provided by dependent claims.Double-valve type forbay that match especially with device according to the present invention, according to the present invention is described its feature by claim 10.
In device according to the present invention, pedestal and saddle are not to form a structural unit.But both are separated from each other and have two planes that are parallel to each other, the corresponding same flat thermal insulation layer of existence between described two planes.On this thermal insulation layer or also have in the two-piece design of thermal insulation layer at two flat interfaces, can be on all directions in described thermal insulation layer inside, that is straight in and transverse to the storage bin end wise carry out relative motion with the compensation thermal stress, thereby the function of this structure no longer depends on the shape of cross section of storage bin, and, also no longer depend on the minimum temperature of blue gas because stress is not to be received but to be reduced.Therefore, device according to the present invention is particularly suitable for supporting the double-valve type storage bin that is used to transport LNG.
Thermal insulation layer according to device of the present invention is preferably made by resistance to compression, shear-stable material, so that this thermal insulation layer can not only hold out against the load of the storage bin of being loaded, and can hold out against the friction force that causes when causing relative motion by the temperature difference.Described material can be a polymer plastic.But preferably can use known laminated plate material/(resin) veneer sheet.Thermal insulation layer can be arranged on the upside of pedestal securely or the downside of the saddle that set on.Under the situation of two-piece type thermal insulation layer, a part is arranged on the upside of pedestal securely, and another part is arranged on the downside of the saddle that is set securely, and the relative motion between two parts occurs on the described two-part flat interface in the thermal insulation layer thus.
According to the present invention, first alternative form is favourable, and each thermal insulation layer is arranged on the upside of its pedestal securely in this alternative form, makes that the relative motion between saddle and the pedestal occurs on the downside of saddle.Its structure is the simplest.
In this design, the fixing best structure with claim 4 of storage bin in ship carried out, to avoid mobile, wherein floor (Steg) prevent the saddle downside and be fixed between the thermal insulation layer on the pedestal respectively transverse to the slip of the longitudinal extension of described floor.At this, the selection of floor and arrange that nature selects like this, make thermal stress reduce unrestricted.Thus, a kind of favourable layout is drawn by claim 5 and 6.At least one floor that laterally extends on saddle along storage bin prevents that storage bin is at this saddle upper edge longitudinal movement.And on other saddle, do not have the floor of horizontal expansion, therefore reducing the necessary relative motion of stress can longitudinally take place there.According to claim 6, the floor of longitudinal extension is fixing storage bin in the horizontal, but allows to take place in the horizontal with respect to its bilateral symmetry ground for reducing the essential relative motion of thermal stress here.If storage bin is parallel to ship vertically (common and preferred arrangement form) with its longitudinal axis, then the floor of longitudinal extension should be positioned at the horizontal centre of ship just, thereby storage bin remains on middle its balance position that also therefore do not disturb of ship under the situation of all possible expansion or contraction.
Prevent that storage bin from preferably designing according to claim 7 from the holding device that pedestal lifts during waviness at sea.This holding device is arranged on the horizontal middle place of ship equally.This has the following advantages with respect to the arrangement form on the storage bin both sides that can imagine, promptly can be owing to recessed slightly not the arching upward and between storage bin and ship shell clip takes place of the hull bottom that takes place really in when unloading when storage bin unloads.
Certainly, in a ship, can support a plurality of storage bins by means of device according to the present invention respectively.Thus, common, known standard is depended in the design of ship.Equally, under the situation of needs, also can load the storage bin of supporting with other liquid dielectric such as chemical, to guarantee to utilize economically ship according to the present invention.
