Abstract
A liquefied natural gas storage tank with an excessive filling prevention device belongs to a low-temperature liquid device and is mainly formed by connecting an outer shell, an inner shell, a heat insulation material, a filling opening, an extraction opening, a safety device and the like, wherein the inner shell is divided into a main cavity and an auxiliary cavity, the auxiliary cavity is positioned at one end of the inner shell, the volume of the auxiliary cavity is 5-10% of the total volume of the inner shell, and the top and the bottom of the auxiliary cavity are respectively provided with a small hole communicated with the main cavity; compared with similar products at home and abroad, the utility model has the advantages of reliable measures for preventing excessive filling, safe storage of liquefied natural gas and the like.
Description
One, technical field: the utility model relates to a kind of cryogenic liquide device, especially a kind of liquefied natural gas (LNG) tank with anti-overfilling device.
Two, background technique: domestic and international existing cryogenic liquid storage tank, promptly store the storage tank of cryogenic liquides such as liquid nitrogen, liquid oxygen, liquid hydrogen, liquid argon and LNG Liquefied natural gas, its anti-overfilling measure generally has two kinds.A kind of method is by observing the demonstration of level meter, when storage tank liquid-level meter shows that tank level has reached maximum and allows to fill liquid level, stops to fill.The deficiency that this method exists is that it is excessive that tank level is filled when malfunctioning or operator can not find in time that tank level has reached maximum and allows to fill liquid level when level meter.Another kind of measure is that storage tank is provided with relief valve, and the extraction mouth of this valve is located at the storage tank maximum and allows to fill the liquid level place.The deficiency that this method exists is must open relief valve could to judge whether storage tank fills excessive.
Three, summary of the invention: the purpose of this utility model is to overcome the prior art above shortcomings, and a kind of liquefied natural gas (LNG) tank with anti-overfilling device is provided.The purpose of this utility model is to realize like this, it is by shell, inner casing, thermoinsulation material, explosion-proof device, fill mouth, safety valve, atmospheric valve, main chamber, auxilliary chamber, aperture, the extraction mouth is formed by connecting, liquefied natural gas (LNG) tank is provided with shell and inner casing, between shell and the inner casing thermoinsulation material is arranged; Explosion-proof device is installed on the shell; Inner casing is set to main chamber and auxilliary chamber, and there is interlayer the centre; Be installed with in the main chamber and fill mouth and extraction mouth, and on the gas phase pipeline of main chamber, safety valve and atmospheric valve are installed; Auxilliary chamber is positioned at an end of inner casing, and volume is 5～10% of an inner casing total measurement (volume), and its top and bottom have aperture to communicate with main chamber respectively.
Filling by LNG Liquefied natural gas of LNG Liquefied natural gas fills cause for gossip now.When filling LNG Liquefied natural gas, the liquid level of main chamber raises very fast, because the aperture of the aperture that auxilliary chamber links to each other with main chamber is very little, the liquid level of auxilliary chamber raises very slow.When the liquid level of main chamber is increased to the top when filling mouthful position, increase owing to fill resistance, fill flow and reduce rapidly, have electrical signal to pass to pump motor this moment, makes the pump stall, stop to fill, thereby it is excessive to have prevented that liquefied natural gas (LNG) tank from filling.This moment, the liquid level of auxilliary chamber was still very low, because the liquid level of main chamber is full of, the LNG Liquefied natural gas in the main chamber flows to auxilliary chamber gradually by following aperture, and is consistent up to the liquid level of main chamber and auxilliary chamber.When using LNG Liquefied natural gas, the liquid level of main chamber reduces, and the liquid level of auxilliary chamber decreases, because the speed that LNG Liquefied natural gas is discharged is slower, the speed that the liquid level of auxilliary chamber and main chamber descends is basic identical, has guaranteed that LNG Liquefied natural gas can use up in the storage tank.
This product is compared with similar products at home and abroad, has advantages such as anti-overfilling measure is reliable, LNG Liquefied natural gas storage safe.
Four, description of drawings: accompanying drawing is the liquefied natural gas (LNG) tank structural representation
Among the figure: 1, shell 2, inner casing 3, thermoinsulation material 4, explosion-proof device 5, fill mouthfuls 6, safety valve 7, atmospheric valve 8, main chamber 9, auxilliary chamber 10, aperture 11, extract out mouthful.
Five, embodiment: in above accompanying drawing, liquefied natural gas (LNG) tank is provided with shell 1 and inner casing 2, between shell 1 and the inner casing 2 thermoinsulation material 3 is arranged; Explosion-proof device 4 is installed on the shell 1; Inner casing 2 is set to main chamber 8 and auxilliary chamber 9, and there is interlayer the centre; Be installed with in the main chamber 8 and fill mouth 5 and extraction mouth 11, and safety valve 6 and atmospheric valve 7 are installed on the gas phase pipeline of main chamber 8; Auxilliary chamber 9 is positioned at an end of inner casing 2, and volume is 5～10% of inner casing 2 total measurement (volume)s, and its top and bottom have aperture 10 to communicate with main chamber 8 respectively.
