Transport vehicle two.There are multiple drawbacks for existing liquid charging system:
1, it before filling pump startup needs that it is pre-chilled, needs to consume partially liq；
2, filling pump is low temperature slewing device, and operation, maintenance, maintenance work amount are big；
3, filling process can not be measured accurately；
4, exist in filling process and risk liquid risk.
Summary of the invention
In order to solve the problems, such as described in background technique, the utility model provides a kind of quick charging device of cryogenic liquid, is
A kind of simple, safe, easy to maintain low-temperature liquid filling device can be without using dynamic while quickly filling cryogenic liquid
Power slewing simplifies charging system equipment, reduces filling process power consumption, conveniently fills and regular job.
In order to achieve the above object, the utility model is implemented with the following technical solutions:
A kind of quick charging device of cryogenic liquid, the pressure-bearing including being connected by cryogenic piping fill tank, liquid vaporization
Device and fill tank inlet valve, vaporizer outlets valve, vaporizer inlet valve and liquid filling valve；Pressure-bearing fills tank entrance by filling
Tank inlet valve is connected with liquid storage groove, and outlet is connected by liquid filling valve with the interface that fills for transporting tank car, liquid vaporizer
Both ends pass through vaporizer outlets valve respectively, vaporizer inlet valve is connected with the top and bottom that pressure-bearing fills tank.
It fills tank upper end in pressure-bearing and is additionally provided with to fill and tank safety valve and fill tank blow valve.
Tapping valve is additionally provided on the pipeline filled between tank inlet valve and liquid storage groove that pressure-bearing fills tank entrance.
The pressure-bearing fills tank height lower than 2 meters of liquid storage groove height or more.
Compared with prior art, the utility model has the beneficial effects that
1, the utility model, which uses, quantitatively to fill cryogenic liquid in advance with the tank that fills of pressure-bearing, to vehicle into
When row is filling, since the vaporization volume ratio of liquid gas is very big, with liquid vaporizer to quantity of fluid vapour few in pressure-bearing tank
Change makes pressure-bearing tank boost rapidly (such as vaporization of liquid oxygen volume ratio 1:800), and the dynamic rotations equipment such as no cryogenic pump, reduction fills
The power consumption of process；Equipment operation is simple, and daily maintenance is convenient；Filling process is safely, conveniently；
2, before the utility model transport tank car reaches, tank can be filled to pressure-bearing in advance and carries out prefilled and boosting, conveying trough
Vehicle can be directly connected to fill pipeline and start charging operation after reaching, save the charging operation time；
4, the utility model can control according to liquid cryogen shell capacity and fill the prefilled amount of liquid of tank to pressure-bearing in advance,
The actual volume of tank can be filled according to pressure-bearing by, which filling, realizes accurate metering, filling process safe and convenient, prevents from filling and emits liquid.
Detailed description of the invention
Fig. 1 is the quick charging device structure connection figure of cryogenic liquid of the utility model.
Wherein: 1- pressure-bearing fills tank 2- liquid vaporizer 3- transport tank car 4- liquid storage groove 5- liquid storage groove 6- and fills
Tinning inlet valve 7- tapping valve 8- pipe network equalizer valve 9- vaporizer outlets valve 10- vaporizer inlet valve 11- fills tank safety
Valve 12- fills tank blow valve 13- liquid filling valve.
Specific embodiment
Specific embodiment provided by the utility model is described in detail below.
As shown in Figure 1, a kind of quick charging device of cryogenic liquid, the pressure-bearing including being connected by cryogenic piping fill tank
1, it liquid vaporizer 2 and tank inlet valve 6, pipe network equalizer valve 8, vaporizer outlets valve 9, vaporizer inlet valve 10 and liquid is filled fills
Fill valve 13；Pressure-bearing fills 1 entrance of tank and is connected by filling tank inlet valve 6 with liquid storage groove 4, outlet by liquid filling valve 13 with
Transport tank car 3 fill interface be connected, 2 both ends of liquid vaporizer pass through respectively vaporizer outlets valve 9, vaporizer inlet valve 10 with
The top and bottom that pressure-bearing fills tank 1 are connected；Pressure-bearing fills 1 upper end of tank can also be by pipe network equalizer valve 8 and gas pipeline network
It is connected.
Tapping valve 7 is additionally provided on the pipeline filled between tank inlet valve 6 and liquid storage groove 4 that pressure-bearing fills 1 entrance of tank.
It fills 1 upper end of tank in pressure-bearing and is additionally provided with to fill and tank safety valve 11 and fill tank blow valve 12.
The pressure-bearing fills 1 height of tank lower than 42 meters of height of liquid storage groove or more.
Specific filling process are as follows:
1, the pressure that liquid storage groove 4 is formed using difference in height to pressure-bearing fill tank 1 quickly, quantitatively fill cryogenic liquid；
2, pressure-bearing fills after tank 1 fills liquid, closes the connection valve 5 and 6 that pressure-bearing fills tank 1 Yu liquid storage groove 4,
It is vaporized boosting by opening liquid vaporizer 2 later, if there is gas pipeline network at scene, can also be connected by gas pipeline network
8 pairs of pressure-bearings of port valve door fill the boosting of tank 1；
Since the vaporization volume ratio of liquid gas is very big, such as the vaporization volume ratio of liquid oxygen is 1:800, thus, it is only required to will
Pressure-bearing fills being vaporized for liquid oxygen very little ratio < 1% in tank 1, it can promotes pressure inside the tank.Simultaneously as vaporization
Liquid fraction it is few, thermal loss when vaporization is also seldom, suitable with the heat lost using cryogenic pump scheme.
3, pressure-bearing fill 1 pressure of tank reach setting pressure after, using pressure-bearing fill tank 1 and transport 3 pressure difference of tank car, will hold
Pressure fills cryogenic liquid in tank 1 and is sent in transport tank car 3, starts to transport 3 charging operation of tank car.
Above embodiments are implemented under premised on technical solutions of the utility model, give detailed embodiment
With specific operating process, but the protection scope of the utility model is not limited to the above embodiments.Side used in above-described embodiment
Method is conventional method unless otherwise instructed.
