Have pressure opening and closing valve, cooling device, the first compressor and the first kinetic pump, first branch be sequentially connected pressure opening and closing valve,
It is connect after cooling device, the first compressor and the first kinetic pump with storage tank, second branch is equipped with valve block, the second compressor
With the second kinetic pump, second branch is connect after being sequentially connected valve block, the second compressor and the second kinetic pump with outer defeated pipe network.
Preferably, in the reuse means of above-mentioned LNG storage tank, first kinetic pump, the second kinetic pump are low
Temperature pump.
Preferably, in the reuse means of above-mentioned LNG storage tank, circulating coolant is equipped in the cooling device.
Preferably, in the reuse means of above-mentioned LNG storage tank, the circulating coolant is N2 and C1-C5.
Preferably, in the reuse means of above-mentioned LNG storage tank, second compressor is low temperature oilless reciprocating pressure
Contracting machine.
Preferably, in the reuse means of above-mentioned LNG storage tank, the valve block is butterfly valve, and the butterfly valve is equipped with row
Cheng Kaiguan.
Compared with the prior art, the advantages of the utility model are:

A little attached drawings obtain other attached drawings.
Fig. 1 show the principle schematic diagram of the reuse means of LNG storage tank in the utility model specific embodiment.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Detailed description, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole implementation
Example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work
The every other embodiment obtained, fall within the protection scope of the utility model.
Join shown in Fig. 1, the reuse means of the LNG storage tank in the present embodiment, including LNG storage tank 1, storage tank 1 is close to top
Side wall is equipped with escape pipe 2, and escape pipe 2 is equipped with the first branch 3 and the second branch 4, and the first branch 3 is equipped with pressure switch
Valve 12, cooling device 5, the first compressor 6 and the first kinetic pump 7, the first branch 3 are sequentially connected pressure opening and closing valve 12, cooling dress
It is connect after setting the 5, first compressor 6 and the first kinetic pump 7 with storage tank 1, the second branch 4 is equipped with valve block 8,9 and of the second compressor
Second kinetic pump 10, the second branch 4 connect after being sequentially connected valve block 8, the second compressor 9 and the second kinetic pump 10 with outer defeated pipe network
It connects.
Further, the first kinetic pump 7, the second kinetic pump 10 are cryogenic pump.
Further, circulating coolant 501 is equipped in cooling device 5.
Further, circulating coolant 501 is N2 and C1-C5.
Further, the second compressor 9 is low temperature oilless reciprocating compressor.
Further, valve block 8 is butterfly valve, and butterfly valve 8 is equipped with travel switch 11.
In the technical scheme, multiple approach solution BOG gas discharges are arranged in the reuse means of LNG storage tank simultaneously
Problem, on the one hand recycling forms LNG, and on the other hand directly conversion forms available fuel and reasonable employment, overall structure letter
It is single at low cost, it improves recovery efficiency and later maintenance is simple, while guaranteeing when one of maintenance of equipment, BOG can continue
Normal recycling.
It is as follows that principle is embodied:
When the intracorporal pressure of tank reaches certain limit, pressure opening and closing valve automatically opens and starts production LNG that BOG liquefies
And be recovered into storage tank, when pressure is excessive or has demand, travel switch control butterfly valve can be regulated and controled and enable Article 2 recycling
