Fig. 2 is the partial rear view of a preferred embodiment of the box frame of the box gas station of the utility model LNG Liquefied natural gas;
The mark of each parts is following in the accompanying drawing: 1, box frame, 2, casing, 3, venetian blind, 4, door is installed, 5, explosion-proof fan.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1 to Fig. 2, the utility model is embodiment comprise:
The box gas station of a kind of LNG Liquefied natural gas comprises: through basin, immersed pump, pressurized machine and the filling apparatus of process pipe connection.
Said basin, immersed pump, pressurized machine and filling apparatus all are installed in box frame 1 inside through lower frame and are connected through process pipe respectively.Particularly, said box frame 1 inner bottom is set with liner, and the LNG Liquefied natural gas that leaks in the installation process can slowly gasify in liner, has guaranteed good Safety performance.
In the utility model, said liner is processed by stainless steel, and the height of this stainless steel inner lining is 1m ~ 1.5m.Stainless steel inner lining has played the effect of embankment, can not need in the time of field erected like this embankment be set, and makes installation process convenient, has reduced field erected workload, can avoid installing simultaneously the influence that receives weather environment.
In the utility model; Said box frame 1 comprises that common casing or size adopt the shipping container of iso standard design; Installation process is easier; Hoisting process is flexible, Security might as well, can play a good protection to the inner basin of casing 2, immersed pump, pressurized machine, filling apparatus with from pressure piping.
Be easy to produce leakage phenomenon in the gas filling of liquefied natural gas process in the working procedure, and then can threaten the Security of aerating.In the utility model, be provided with an installation door 4 along the left side beam upset in the front of casing 2; Top on two sides, casing 2 front and back is provided with venetian blind 3, is the equi-spaced apart setting between the adjacent venetian blind 3 on the two sides, front and back; Top, left side on two sides, casing 2 front and back is provided with explosion-proof fan 5.
The workflow of the utility model can be divided into the flow process of unloading, LNG filling flow process, standby flow process and transfer saturated flow process, and its detailed process is following:
