The vaporizer 500 is also connected by breather pipe 600 with the air inlet of each tank car.
In embodiment of the present utility model, when an at least tank car, which is parked in tank car, parks position 100, pass through connection of unloading
Tank car is connected by pipe 400 with LNG storage tank 200, and is connected tank car with vaporizer 300 by vaporizing connecting tube 500.Now, beat
The first valve 410 and the second valve 510 are opened, it is 5 to keep the opening ratio of the first valve 410 and the second valve 510:1~10:1, just
It is that most liquified natural gas is to have flowed to LNG storage tank, and the liquified natural gas of only sub-fraction flows to vaporizer 300 and entered
It is back to after row vaporization in the tank body of tank car and Quick-unloading is aided in air pressure.So, the liquified natural gas in the tank body of tank car exists
Under itself hydraulic pressure and under the air pressure of the natural gas of vaporization, Quick-unloading can be realized.
For example, being provided with 5 tank cars parks position 100, be designated as respectively the first tank car parks position, the second tank car parks position,
Three tank cars park position, the 4th tank car parks position and the 5th tank car parks position.When the first tank car parks position, the second tank car parks position,
3rd tank car parks position, the 4th tank car parks position and the 5th tank car is parked to correspond on position and all parked tank car, and tank car is with unloading
After the completion of connecting tube 400, vaporization connecting tube 500 are all connected with, 510,5 tank cars of the first valve 410 and the second valve can be opened
Start to unload.It is that itself natural gas is carried out that first tank car, which parks the gaseous natural gas source that tank body in the tank car parked on position is passed through,
Natural gas after liquified natural gas is vaporized in natural gas after vaporization, or the tank body of other 4 tank cars, that is, it is more
Liquified natural gas in individual tank car can flow to the tank body of wherein any one or more tank cars after vaporizer 300 is vaporized
In.According to it was verified that after this path by adding vaporizer 300, liquified natural gas is from tank car through connection of unloading
When pipe 400 flows to LNG storage tank 200, the speed that liquid level declines in tank body is 1m/s.
When it is implemented, in the tank car Quick-unloading system, the arrival end of first valve 410 is additionally provided with pressure
Power inductor（It is not shown）.It can detect whether connecting tube 400 of unloading has connected with the tank body of tank car in real time by pressure sensor
Connect, so after completing to connect, technical ability is opened the first valve 410 and unloaded.Pressure inductor serves carrying for valve opening door
Show the effect of device, avoid connection and do not complete the situation for being switched on valve, avoid liquid LNG leakage.Specifically, the pressure
Model PT500-500, PT500-501, PT500-502, PT500-503 or PT500-504 of power inductor.
