Abstract
Provided is a liquefied natural gas storage tank belonging to a low temperature liquid storage and transportation device. The utility model comprises an outer shell and an inner shell which are connected together. The inner shell is provided with a filling port and an out-drawing port of the liquefied natural gas. Thermal insulation materials are arranged between the inner shell and the outer shell. The outer shell is provided with an anti-explosion device. The inner shell is provided with a security valve and an atmospheric valve. A metal tube with a good thermal conduction performance and a small weight is arranged in the inner shell. The metal tube is arranged vertically and goes through the whole storage tank. The upper end of the metal tube is welded on the upper end of the inner wall of the storage tank. The lower end is hanged in the air. The upper end of the metal tube is opened with small holes which are interlinked with the air vent of the storage tank. Compared with similar products in domestic and abroad, the utility model possesses the advantages of a low speed of transportation tank boosting, little evaporating loss, safety and reliability etc. in a static state.
Description
One, technical field: the utility model relates to a kind of cryogenic liquide storage and transportation apparatus, especially liquefied natural gas (LNG) tank.
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, be generally double layer construction, thermoinsulation material is arranged between the inside and outside shell.This cryogenic liquid storage tank is when static state, owing to continue to absorb heat from the external world, the cryogenic liquide temperature raises in the storage tank.But because of the heat that storage tank unit internal surface area absorbs basic identical, and the density of storage tank upper gaseous phase is much smaller than the density of bottom liquid phase, thereby the temperature of storage tank gas phase is higher than the temperature of bottom liquid phase, make the pressure of storage tank be higher than the saturation pressure of cryogenic liquide under liquidus temperature, it is too fast to cause storage tank to boost, shorten the holding time of cryogenic liquide, caused the too much loss of cryogenic liquide, and brought potential safety hazard thus.
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 is provided.The purpose of this utility model is achieved in that it is by shell, inner casing, thermoinsulation material, explosion-proof device, fills mouth, safety valve, atmospheric valve, metal tube, aperture, extraction mouth and be formed by connecting, liquefied natural gas (LNG) tank is provided with shell and inner casing, and thermoinsulation material is arranged in the middle of shell and the inner casing; Explosion-proof device is installed on the shell, LNG Liquefied natural gas is being set on the inner casing is filling mouth and extract mouth out, and on the gas phase pipeline of inner casing, safety valve and atmospheric valve are being installed; Metal tube is welded on the inwall upper end of storage tank inner casing, and sky is revolved in the lower end, and the upper end of metal tube has aperture and communicates with the storage tank gas phase, and metal tube is good heat-transfer, lightweight particulate metal material.
When liquefied natural gas (LNG) tank is used, the LNG Liquefied natural gas of uniform temperature, pressure is housed in the liquid phase inner casing, filling by filling cause for gossip of LNG Liquefied natural gas is existing, extracts out by extracting cause for gossip out existing.Because inner casing inside is provided with good heat-transfer, lightweight metal tube, and this metal tube makes the gas phase temperature of LNG Liquefied natural gas identical with liquidus temperature all the time through the gas-liquid two-phase of storage tank, and promptly LNG Liquefied natural gas is in saturation state all the time.So, owing to importing into of external heat, the temperature of LNG Liquefied natural gas slowly raises, and its saturation pressure and then raises.Because of gas-liquid two-phase is in saturation state always, greatly reduce the rate of rise of liquefied natural gas (LNG) tank, increased the storage time of LNG Liquefied natural gas, reduced the evaporating loss of LNG Liquefied natural gas.
Advantages such as this product is compared with similar products at home and abroad, and the storage tank rate of rise is slow when having static state, evaporating loss is few, safe and reliable.
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, metal tube 9, extract out mouthful, 10, aperture.
Five, embodiment: in above accompanying drawing, liquefied natural gas (LNG) tank is provided with shell 1 and inner casing 2, in the middle of shell 1 and the inner casing 2 thermoinsulation material 3 is arranged; Explosion-proof device 4 is installed on the shell 1; LNG Liquefied natural gas is being set on the inner casing 2 is filling mouth 5 and extract mouth 9 out, and safety valve 6 and atmospheric valve 7 are being installed on the gas phase pipeline of inner casing 2; Metal tube 8 is welded on the inwall upper end of storage tank inner casing, and sky is revolved in the lower end, and the upper end of metal tube 8 has aperture 10 and communicates with the storage tank gas phase, and metal tube 8 is good heat-transfer, lightweight particulate metal material.
