Description
Technical field
The utility model is related to the technical fields of LNG transport vehicle parts, especially a kind of that there is liquid medium to remove stage makeup and costume certainly
The LNG tank vehicle set.
Background technology
LNG is the abbreviation of liquefied natural gas (liquefied natural gas), liquefied natural gas carrier vehicle abbreviation LNG
Transport vehicle.Most important tool of the LNG tank vehicle as LNG land transports has been obtained because it is with very strong flexibility and economy
To widely applying.LNG basins (refrigerated storage tank) are the component parts of LNG transport vehicles, belong to the storage facilities LNG storages of LNG
The particularity of tank：The LNG basins of large capacity, due to being to work in the state of ultralow temperature (- 162 DEG C), with other oil
Chemical storage tank ratio has its particularity.Simultaneously in operation since the LNG of storage is in fluidized state, when outside heat invades
When, or impact, atmospheric pressure when due to filling variation, all the LNG of storage will be made persistently to be gasificated as gas, in running thus
It must take into consideration the storage control of pressure inside the tank, the extraction of gasifying gas, processing and refrigeration cold insulation etc..In addition, the safety of LNG basins
Valve, liquid level meter, thermometer, inlet/outlet pipe the first-class associate member of telescoping connection also have to it is low temperature resistant.The safety device of basin is low
Under temperature, low pressure, it is also necessary to can reliably start.LNG from air source is transported to by road tanker or tank container vehicle and uses gas
After the LNG supply stations of city, tank car storage tank is boosted into 0.6MPa (or by station using the air temperature type boosting gasifier on tank car
The supercharging gasifier of unloading being arranged boosts to tank container vehicle).Pressure of storage tank is down to about 0.4MPa simultaneously, makes tank car
LNG in tank car is discharged into supply station storage tank by the pressure difference that about 0.2MPa is formed between LNG storage tank using this pressure difference.It unloads knot
Shu Shi recycles the natural gas in tank car by unloading deck vapor delivery line.Due to there was only the pressure of 0.2MPa between tank car and LNG storage tank
Difference so that long time is needed when unloading, and each pipeline is various, fall into disarray is extremely inconvenient in construction.
Utility model content
The purpose of this utility model is to provide a kind of overcome the deficiencies in the prior art, simple in structure, easy to use to unload
The LNG tank vehicle that time is short, pipe-line layout reasonably has liquid medium dumping device.
To achieve the goals above, the technological means that the utility model is taken is：
LNG tank vehicle with liquid medium dumping device, including tank car ontology, key are：Further include being fixed on tank car
The high pressure dumping device of rear body, high pressure dumping device include that pressure piping, heat riser and gas phase pipeline, pressure piping are set
It sets in the side of tank car body tail section and is connected to the inside of tank car ontology, gas phase pipeline is arranged in the another of tank car body tail section
Side is simultaneously connected to by heat riser with pressure piping, and the end of gas phase pipeline is connected to the inside of tank car ontology, and tank car ontology exists
The centre of pressure piping and gas phase pipeline is provided with liquid phase pipeline.
The heat riser is the parallel cartridges of multiple-layer horizontal setting, each horizontally disposed pipeline of layer and its phase up and down
Adjacent pipeline all makes its longitudinal S-shaped setting by bend pipe connection, and multi-disc heat exchange is densely covered on the parallel cartridges of heat riser
Fin.
The heat riser is connected to pressure piping by bellows, and the lateral wall of bellows is provided with protective layer.
The heat riser is fixed on the lower section of tank car body tail section by fixed border.
The fixed border includes former and later two baffles, and angle iron bracket is fixed between former and later two baffles, is risen
The parallel cartridges of warm device are fixed on by " several " font fixing sleeve and fixing bolt above angle iron bracket, fixed border and tank car
The junction of ontology is fixed with reinforcing plate, and the bottom of the baffle and tank car ontology of reinforcing plate and fixed border is fixed into right angle trigonometry
Shape structure.
The utility model has the beneficial effects that：Due to being provided with pressure piping, heat riser and gas phase pipeline, when in tank car
LNG stream go out to heat riser, make from liquid gasification to become gas since temperature raises, then enter tank from gas phase pipeline
Car improves the pressure inside tank car so that the pressure in tank car can increase to 1.4MPa, in the feelings that pipeline diameter is constant
Under condition, the flow rate of liquid of LNG is improved, shortens the time of unloading, and the pipe-line layout of tank car body tail section is designed from new, from
Side to the other side is respectively pressure piping, liquid phase pipeline and gas phase pipeline, and when construction is more convenient.
