The utility model discloses LNG storage system places onshore, and the LNG output system is placed on water, the last branch pipe that is provided with of LNG conveying system, the filling of LNG fuel -power boats and ships in the time of can satisfying big water -level fluctuation.

Description

Adapt to the LNG filling apparatus of Large Water drop
Technical field
The utility model is related to LNG filling apparatus, and in particular to a kind of LNG filling apparatus of adaptation Large Water drop.
Background technology
Natural gas is a kind of widely used clean energy resource in the world today, and LNG (liquefied natural gas) is through place by natural gas After reason, and -160 DEG C or so storing liquid products are cooled to, its volume is 1/600 under gaseous state, had in storage, transport bright Aobvious advantage.
At present, China's natural gas market is fast-developing, and the shared ratio in energy supply of natural gas increases sharply, naturally Gas supply problem, LNG supply problems particularly waterborne are increasingly highlighted, therefore the construction of LNG filling stations (filling landing stage) urgently adds Speed.
The domestic general more method that LNG filling is carried out to ship ship filling, bank station are filled to ship for tank car and Wholesale ship-to-ship fills three kinds.Tank car is docked on harbour to ship filling usually tank car and LNG fuel ships is filled;Bank station pair Usually fixation means are filled by pipeline to LNG fuel ships on the bank for ship filling;Wholesale ship-to-ship filling is usually by LNG Storage, filling facility and supporting power supply, fire fighting device be each provided on the LNG landing stages on navigation channel, by landing stage to LNG fuel Ship is filled.
Do not accounted in above-mentioned three kinds conventional LNG charging methods when the height of water is larger, the distant situation of offshore.If A kind of LNG charging methods for being adapted to the distant situation of Large Water drop, offshore of meter, can enrich carries out LNG to ship The mode of filling, advances the construction of LNG filling stations.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of LNG of adaptation Large Water drop Filling apparatus, it efficiently solves the LNG fuels and energies ship filling in the case of Large Water drop, offshore are distant.
To achieve the above object, a kind of LNG filling apparatus for adapting to Large Water drop designed by the utility model, described LNG filling apparatus include installing LNG storage tank on the coast, and the LNG storage tank is connected with LNG pump, and the LNG pump is connected with setting Vacuum tube on ramp, the vacuum tube other end is connected with flexible pipe access bridge and landing stage in turn, and the middle-end of the vacuum tube connects Bye-pass vacuum tube is connected with, the bye-pass vacuum tube other end is connected with flexible pipe access bridge and landing stage in turn.
Further, Subzero valve is installed on the vacuum tube and the vacuum tube at bye-pass vacuum tube junction two ends.
Yet further, bye-pass Subzero valve is installed on the bye-pass vacuum tube.
LNG storage tank and LNG pump composition LNG storage systems on the bank, it is used to store LNG, and is provided to LNG induction systems LNG。
Vacuum tube, Subzero valve, bye-pass vacuum tube and bye-pass Subzero valve composition LNG induction systems, it is used for defeated Can adjust accordingly to meet LNG fuel ship filling demand when sending LNG and SEA LEVEL VARIATION.
Flexible pipe access bridge and the landing stage containing filling arm constitute LNG output systems, and it is used to export LNG, to LNG fuels and energies Ship is filled.
LNG induction systems are connected with LNG storage systems and LNG output systems respectively by being provided with the pipeline of in-line relief valve Connect;LNG storage systems mainly include handling, storage and supporting power supply, fire-fighting, the control shore-based LNG station of facility of LNG Area;LNG output systems are filling landing stage/buoyancy tank waterborne, do not carry out LNG storages, only set the filling such as LNG filling guns, filling arm and set Apply.
When SEA LEVEL VARIATION is larger, LNG output systems change with SEA LEVEL VARIATION, and branch is set in LNG induction systems Pipe is segmented, and when water level rises to certain altitude, closes existing interface and intends interface isolating valve, then adjusts LNG outputs System position, makes interface in LNG output systems be connected with the branch pipe valve of correspondence position in LNG induction systems, so as to realize water LNG output systems remain able to normal work during the change of position.
The beneficial effects of the utility model:
The utility model LNG stocking systems are placed on the coast, and LNG output systems are placed on the water, are set in LNG induction systems Branch pipe is equipped with, the filling of LNG fuels and energy ships when disclosure satisfy that Large Water changes.
Brief description of the drawings
Fig. 1 is the LNG filling apparatus schematic diagrames of adaptation Large Water drop of the present utility model.
In figure:LNG storage tank 1, LNG pump 2, vacuum tube 3, Subzero valve 4, landing stage 5, bye-pass vacuum tube 6, bye-pass low temperature Valve 7, flexible pipe access bridge 8.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so as to art technology Personnel understand.
As shown in Figure 1:The LNG filling apparatus of Large Water drop are adapted to, the LNG filling apparatus include installing on the coast LNG storage tank 1, LNG storage tank 1 is connected with LNG pump 2, and LNG pump 2 is connected with the vacuum tube 3 being arranged on ramp, the other end of vacuum tube 3 It is connected with flexible pipe access bridge 8 and landing stage 5 in turn, the middle-end of vacuum tube 3 is communicated with bye-pass vacuum tube 6, and bye-pass vacuum tube 6 is another End is connected with flexible pipe access bridge 8 and landing stage 5 in turn.
Subzero valve 4 is installed on vacuum tube 3 and the vacuum tube 6 at the junction two ends of bye-pass vacuum tube 6.Bye-pass vacuum Bye-pass Subzero valve 7 is installed on pipe 6.
Charging method is carried out using above-mentioned LNG filling apparatus:
Vacuum tube 3 is entered by LNG pump 2 from LNG storage tank 1, it is dynamic to LNG fuel after flexible pipe access bridge 8 and landing stage 5 Power ship is filled, when water level rises to certain altitude, the Subzero valve 4 and Subzero valve 5 closed on vacuum tube 3, the section LNG nitrogen displacements in pipeline, then adjust the position of landing stage 5 and flexible pipe access bridge 8, make its with bye-pass vacuum tube 6 on Correspondence valve connection, after the completion of connection, opens Subzero valve 4 and bye-pass Subzero valve 7, so as to realize can during SEA LEVEL VARIATION Bio-occlusion LNG fuels and energy ships are filled, otherwise when water level is reduced.
Other unspecified parts are prior art.Although above-described embodiment is made that detailed to the utility model Description, but it is only a part of embodiment of the utility model, and rather than whole embodiments, people can also be according to this implementation Example obtains other embodiment under the premise of without creativeness, and these embodiments belong to the utility model protection domain.
