Description
Technical field
The utility model relates to a kind of LNG storage tank, is specifically related to a kind of special-shaped self-support type LNG storage tank being applicable to concrete caisson.
Background technique
LNG Liquefied natural gas (LNG) is that when being cooled to-162 DEG C of low temperature at ambient pressure by rock gas, rock gas changes liquid state into by gaseous state, and volume is about with amount rock gas volume 1/600, and density is about 450kg/m
3.LNG is colourless, tasteless, nontoxic and non-corrosiveness.
LNG is usually by professional traffic ship, and by the mode of sea-freight, by liquefaction, factory is transported to LNG receiving station, is stored in LNG storage tank, after gasifying, by Cemented filling to user again.In LNG Industry Chain, the storage of LNG is a very important link.
In European norm EN14620, GB GB/T26978, the common pot of Large LNG storage tank has singly to be held tank, double volume tank, entirely holds tank, several pot of film tank.There are some researches show, along with the increase of tank volume, above-mentioned pot unit volume storage tank construction cost is all on a declining curve, and scale effect is more obvious.The increase that storage tank maximization economic advantages are mainly reflected in tank appearance can improve land use capability and reduce storage tank BOG relative evaporation more.In addition along with the increase of LNG industrial chain cargo ship ship appearance, the increase of quantity and LNG increase the increase of receiving station's quantity newly, also need the LNG storage tank of more volume supporting with it.In general, maximization (160,000 sides, the above storage tank of 200,000 side) is current Large LNG Tank Capacity development trend place.But specification limits construction technologies such as the restriction of primary tank wall panel thickness, large volume welding and brings bottleneck to the large scale development of above-mentioned existing pot.
List land at present holds the self-supporting storage tanks such as tank, double volume tank, full appearance tank and can't directly be applied on marine LNG storage facility.Namely allow to application, because above three kinds of storage tanks are all flat cylinder modes, and offshore floating type or gravity type LNG storage organization are generally square box shapes, if be installed on wherein, can cause larger space waste.
Model utility content
The purpose of this utility model is to provide a kind of special-shaped self-support type LNG storage tank being applicable to concrete caisson, solves existing LNG storage tank and is not suitable for the problem that sea stores and space waste is larger; The static pressure of liquid goods and kinetic pressure can be passed to hull or concrete caisson by the special-shaped self-support type LNG storage tank that the utility model provides, and reduce the stress of tank body.
Special-shaped self-support type LNG storage tank for concrete caisson provided by the utility model, the LNG storage tank of the side's of comprising bodily form;
The bottom of described LNG storage tank is provided with several supporting posts, is provided with spacing described in several between supporting post.
In described special-shaped self-support type LNG storage tank, the height of described supporting post is 0.5 meter ~ 1.0 meters; By described supporting post, described special-shaped self-support type LNG storage tank is erected in concrete caisson, avoids LNG storage tank and contacts with the direct of concrete caisson, to reduce the low temperature of LNG storage tank to the impact of the performance of concrete caisson; Simultaneously owing to being provided with spacing between described supporting post, thus between the bottom of LNG storage tank and the bottom of concrete storage tank, define the space that several gases circulate, scattering and disappearing of the cold of LNG storage tank transmission can be improved further, to reduce the impact on concrete caisson performance, improve the working life of concrete caisson.
In described special-shaped self-support type LNG storage tank, by the storage tank body side of the being arranged to bodily form, compared to existing circle tube tank body, there is the advantage that space availability ratio is large.
In described special-shaped self-support type LNG storage tank, described supporting post is made up of wood veneer square, and because wood veneer square compares the cryophylactic performance of concrete pillar more by force, the ability of buffering is also stronger, lower the destruction of low temperature to concrete caisson with this, increase the working life of concrete caisson.
In described special-shaped self-support type LNG storage tank, the inner side of the wallboard of the inner canister of described LNG storage tank is provided with several stiffening rings, and outside is provided with several and strengthens fin.
In described special-shaped self-support type LNG storage tank, described reinforcement fin comprises hoop and strengthens fin and longitudinal reinforced rib sheet, and described hoop strengthens fin and several compartments of described longitudinal reinforced rib sheet formation arranged in a crossed manner.
In described special-shaped self-support type LNG storage tank, be provided with cold insulation block in described compartment, described cold insulation block is formed article, directly can be embedded in the described compartment of fin formation, shorten the duration of fill insulant material.Further, described cold insulation block can make the reliability of total strengthen, and there will not be the problem of traditional bulk thermal insulation material generation loss accident.
In described special-shaped self-support type LNG storage tank, be filled with glass fibre and/or pearlife in described cold insulation block, described cold insulation block is wound around some layers of thermoinsulation material outward.
In described special-shaped self-support type LNG storage tank, be provided with the dividing plate axially arranged along it in the cavity of described LNG storage tank, described dividing plate can reduce the rolling of tank inside LNG.
In described special-shaped self-support type LNG storage tank, the corner of described LNG storage tank is round and smooth setting, decreases the phenomenon that stress is concentrated.
The utility model abnormity self-support type LNG storage tank tool has the following advantages:
Due to the setting of supporting post, the utility model abnormity self-support type LNG storage tank is not directly contacted with concrete caisson, so LNG storage tank is expanded with heat and contract with cold, the static stress and distortion produced can not act on concrete caisson, improves the usability of concrete caisson.
Accompanying drawing explanation
Fig. 1 is the sectional drawing of the utility model abnormity self-support type LNG storage tank.
In figure, each mark is as follows:
