Abstract
The utility model discloses a kind of LNG storage tank being provided with supporting post.It comprises LNG storage tank body; Described LNG storage tank body comprises outer tank and is located at the inner canister in described outer tank; Be provided with supporting post in described LNG storage tank, and described supporting post is connected with the dome of described outer tank; Cold insulation material is filled with between the tank skin of described supporting post and described inner canister; Described supporting post is located at the center position of described LNG storage tank.The utility model fills cold insulation material between supporting post and inner canister, and arranges heating equipment in supporting post, enables the supporting post being in cryogenic liquide encirclement for a long time keep normal working.
Description
Technical field
The utility model relates to a kind of LNG storage tank being provided with supporting post, belongs to LNG Liquefied natural gas (LNG) technical field of memory.
Background technique
Current LNG holds in storage tank entirely, there is not the structure of pillar.Due to the large scale development trend of storage tank, the span of dome is increasing.But theoretical proof, the span of dome can not infinitely increase.When tank volume increases further, the span of value will become the major reason of restriction storage tank large scale development.Solving dome across the unlimited problem increased, is one of difficult point of storage tank future development.
Under normal circumstances, post can be arranged in the middle of the building that span is larger to support.But because LNG storage tank belongs to low-temperature (low temperature) vessel, the design method of building with other exists larger difference, therefore, the difficulty increasing supporting post in storage tank is larger.And the requirement of the concrete structure of longspan to construction is higher, increases the difficulty of construction of whole storage tank.
Model utility content
The purpose of this utility model is to provide a kind of LNG storage tank being provided with supporting post, by extension supporting post in tank body, improves the span of value, adds single tank volume, decrease the floor space of LNG storage tank per unit volume, reduce storage tank construction cost.
The LNG storage tank being provided with supporting post provided by the utility model, it comprises LNG storage tank body; Described LNG storage tank body comprises outer tank and is located at the inner canister in described outer tank; Be provided with a supporting post in described LNG storage tank, and described supporting post is connected with the dome of described outer tank; Cold insulation material is filled with between the tank skin of described supporting post and described inner canister.
In described LNG storage tank, described supporting post is located at the center position of described LNG storage tank, for supporting dome, and then increases the span of dome.
In described LNG storage tank, in described supporting post, be provided with heating equipment, remain on normal temperature state to make described supporting post.
In described LNG storage tank, described supporting post is connected with temperature-detecting device, to monitor the temperature variation of described supporting post at any time, ensures that described supporting post (reinforced column) is within normal working temperature scope all the time.
In the utility model LNG storage tank, described supporting post is connected with the dome at top with the cushion cap of bottom, and passes from described inner canister center region; The cold insulation materials such as perlite are filled between described interior tank shell and described supporting post.
The LNG storage tank tool that the utility model is provided with supporting post has the following advantages:
The supporting structure of post is not set in existing storage tank, the maximum span of dome is restricted, and the utility model increases supporting post in storage tank, adds the span of dome, and the volume of storage tank can be made to expand further.Meanwhile, under the condition that equal tank holds, the ratio of height to diameter that supporting post can reduce storage tank is set, reduces storage tank center of gravity, reduce geological process power; Meanwhile, the area in the region that can lay out pile increases, and can increase total bearing capacity of pile foundation.Tank holds to be increased, and can reduce the unit price of storage tank, the cost of investment of storage tank can obtain larger economic benefit, reduce the quantity of storage tank simultaneously, reduces storage tank region floor space.The utility model fills cold insulation material between supporting post and inner canister, and arranges heating equipment in supporting post, enables the supporting post being in cryogenic liquide encirclement for a long time keep normal working.
Accompanying drawing explanation
Fig. 1 is the overall schematic that the utility model is provided with the LNG storage tank of supporting post.
Fig. 2 is the bottom Local map that the utility model is provided with supporting post in the LNG storage tank of supporting post.
In figure, each mark is as follows:
1 supporting post, 2 cold insulation materials, 3 inner canisters, 4 cushion caps, 5 heating equipments, 6 furred ceilings, 7 domes.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further, but the utility model is not limited to following examples.
As shown in Figure 1, for the LNG storage tank being provided with supporting post that the utility model provides, comprise the LNG storage tank body be located on cushion cap 4 (reinforced concrete material), it comprises outer tank (not marking in figure) and is located at the inner canister 3 ((9%Ni steel plate, the top of inner canister 3 is provided with furred ceiling 6) in outer tank.Be provided with a supporting post 1 at the center position of LNG storage tank, it is reinforced concrete material, and supporting post 1 is connected with the dome of outer tank, for supporting dome, increases the span of dome.Cold insulation material 2 (as perlite etc.) is filled with between supporting post 1 and the tank skin of inner canister 1.This cold insulation material principle is similar to the cold insulation between inner canister with storage tank outer tank, to reduce the heat trnasfer in tank between LNG liquid and supporting post.
In order to make supporting post 1 remain on normal temperature state, arrange heating equipment 5 in supporting post 1, this heating equipment 5 makes supporting post 1 namely directly not contact with external environment condition, also can be in normal working temperature for a long time.
In order to ensure that supporting post 1 is within normal working temperature scope all the time, this supporting post 1 is connected with temperature-detecting device (not shown), to monitor the temperature variation of described supporting post 1 at any time.
The utility model is provided with the LNG storage tank of supporting post, owing to there is cold insulation material between supporting post 1 and inner canister 3, and supporting post 1 outer installment heating equipment 5, therefore in precooling with operation, supporting post 1 can not produce excessive deformation due to low temperature.
The utility model is provided with the LNG storage tank of supporting post, and the supporting post 1 due to storage tank is arranged on the central position of storage tank, is therefore rising in the process of top, the stabilizer in dome 7 center portion should be located at outside supporting post 1, and rising in the process of top, should strictly monitor whole process, prevent the accidents such as inclination.
