State low-temperature storage tank 101 to connect.When described need liquid feeding until liquid feeding car 103 time, described controller control
Described 3rd electromagnetic valve the 203, the 5th electromagnetic valve 205 and described check valve 210, due to described second
Check valve 210 and the 5th electromagnetic valve 205 on exhaustor 112 are opened, described low-temperature storage tank
With described, 101 treat that liquid feeding car 103 connects with second exhaust pipe 112 by downtake pipe 111, described
Low-temperature storage tank 101 and described treat that liquid feeding car 103 reaches same pressure, in described low-temperature storage tank 101
Liquefied natural gas is flowed to by described second discharging tube 110 and the first discharging tube 109 due to gravitional force
Described treat liquid feeding car 103.
Treat described in the liquefied natural gas in low-temperature storage tank 101 cannot rely on the entrance of described liquefied natural gas
During liquid feeding car 103, controller can control described 6th electromagnetic valve 206 and open, and makes described flash steam
Holding vessel 107 connects with the top of described low-temperature storage tank 101, due to described flash steam holding vessel 107
Internal memory contains substantial amounts of flash steam, and internal pressure is the highest, and flash steam flows in described low-temperature storage tank 101
Top, make the pressure of described tank car 102 raise, by the liquefied natural gas in described tank car 102 from
Treat liquid feeding car 103 described in the bottom press-in of low-temperature storage tank 101, complete liquid feeding.
Controller can also control described 7th electromagnetic valve 207 and the 8th electromagnetic valve 208 is opened, and makes institute
State low-temperature storage tank 101 or described in treat in liquid feeding car 103 flash steam flow into described flash steam and reclaim storage
Device.Concrete, make described flash steam flow into described heater 104 by gas recovery pipe 113, can
To be heated to room temperature, through the heating of heater 104, then it is emitted into surge tank 105, the present embodiment
The volume of middle surge tank 105 treats the volume of automobile-used low-temperature storage tank of liquid feeding car 103, so described in being more than
The flow velocity of flash steam can be increased, make described in treat that the air pressure of automobile-used low-temperature storage tank of liquid feeding car 103 is rapid
Decline, beneficially liquid feeding.Moreover, when opening the 9th electromagnetic valve 209 and compressor 106,
Owing to heater 104, surge tank 105, compressor 106 and described flash steam holding vessel 107 are the most logical
Crossing room temperature pipeline 114 to connect, the flash steam in described surge tank 105 is carried out by described compressor 106
Compression, now the flash steam temperature after compression has certain reduction, is then stored in the storage of described flash steam
Deposit tank 107, in case tank car 102 unload and until liquid feeding car 103 liquid feeding need use flash steam pressurization time
Use.
It is generally less than-100 degrees Celsius due to flash steam, therefore this utility model have employed heating
Flash steam is heated by device 104, then in leaving surge tank 105 in, and described surge tank 105
Then can use low temperature resistant material, and described compressor 106 can also use low temperature
Immersed pump, uses conventional air pump, it is possible to reduce cost.
Described surge tank 105 can also reduce flash steam from heater 104 to described compressor 106
Flow velocity, has the function of temporarily storage, it is possible to make the efficiency of heating surface of described heater 104 improve, keep away
Exempting from heats the best, the flash steam making temperature extremely low enters into described compressor 106, to described compression
Machine 106 causes damage.
A small amount of vaporization is had when the liquefaction in low-temperature storage tank 101 is natural, described after being vaporizated into flash steam
Air pressure in low-temperature storage tank 101 can raise, and described pressure transducer can be by the gas in low-temperature storage tank 101
Pressure value is transferred to described controller by the signal of telecommunication, and the pressure in described low-temperature storage tank 101 reaches to control
During the first threshold that device sets, described controller controls described 7th electromagnetic valve 207 and the 8th electromagnetic valve
208 open, and make the flash steam of vaporization enter described heater 104, and are stored in described flash distillation further
In vapour holding vessel 107.
Contrary, the air pressure in pressure transducer detects described flash steam holding vessel 107 is higher than control
During the Second Threshold that device processed is arranged, controller controls described 4th electromagnetic valve 204 and the 6th electromagnetic valve 206
Open, make the flash steam in described flash steam holding vessel 107 enter from the bottom of described low-temperature storage tank 101
Enter, the liquefied natural gas stored due to the bottom of described low-temperature storage tank 101, the temperature of this liquefied natural gas
Spending extremely low (about-160 degrees Celsius), part flash steam will be liquefied as liquefied natural gas, can subtract
The pressure of little described flash steam holding vessel 107.Described flash steam holding vessel 107 is additionally provided with relief valve
211, when the pressure in described flash steam holding vessel 107 reaches three threshold value that controller sets, and
And the force value of described low-temperature storage tank 101 equally higher than safety value time, described controller controls described peace
Full valve 211 is opened, and reduces the air pressure of described flash steam holding vessel 107, prevents potential safety hazard.
In sum, flash steam of the present utility model reclaims storage device and can will treat the flash distillation of liquid feeding car
Vapour is collected storing；During the liquefied natural gas of tank car is unloaded or treat the liquid feeding process of liquid feeding car
In, utilize the flash steam collected that tank car or low-temperature storage tank are carried out supercharging, make the liquefaction in tank car natural
Gas transmission is to described low-temperature storage tank, or makes to treat liquid feeding described in the LNG transfer person in low-temperature storage tank
Car.During flash steam is collected storing, it is provided with heater, it is possible to first carried out by flash steam
Heating, then it is compressed storage, and avoid use low temperature immersed pump, reduce cost, and
Flash steam can be recycled, reduce environmental pollution.Flash steam holding vessel is provided with peace
, when the pressure of flash steam holding vessel can be prevented further too high, there is potential safety hazard in full valve.
