As shown in Figure 2, in the present embodiment, basin 1 comprises outer container 10 and inner container 11, has mezzanine space between inner container 11 and outer container 10.Basin 1 also comprises top liquid inlet pipe 13, bottom liquid inlet pipe 12 and gas phase pipe 14.Wherein the top in inner container 11 is stretched in one end of top liquid inlet pipe 13, one end of bottom liquid inlet pipe 12 is stretched into inner container 11 inside and extends to bottom it, one end of gas phase pipe 14 is communicated in the tip portion of inner container 11 inside, and the other end is communicated in the gas returning port 31 of unloading of tank car.In addition, in order to make basin 1 preserve LNG maximum capacity, in the present embodiment, basin 1 volume is 54m 3, meeting in state's laws basis for establishing, making the capacity of basin 1 reach maximization, improve storage efficiency, improve Economy.
As shown in Figure 2, in the present embodiment, pump pond 40 is arranged in the mezzanine space between inner container 11 and outer container 10, and outer container 10 outside is stretched out in the upper end portion in pump pond 40, and pump pond 40 and inner container 11 pass through pipeline communication.Specifically, being communicated with pump pond 40 with the pipeline of inner container 11 is bottom drain pipe 15, and bottom this, drain pipe 15 is communicated with bottom and the pump pond 40 of inner container 11, but not as limit.In addition, immersed pump 41 is arranged in pump pond 40, and immersed pump 41 is lower than the height of inner container 11 bottom surface, but not as limit.The structure of this kind of band pump basin, compared with existing gas station, without the need to before use immersed pump, precooling is carried out to it, in present embodiment, because immersed pump 41 and pump pond 40 are arranged at inner container 11 with the mezzanine space of outer container 10, it can be made unanimously to keep lower temperature, make this skid-mounted gas filling station without the need to namely liquid status to be unloaded can be entered fast to immersed pump precooling, significantly improve the speed that gas station comes into operation, improve the working efficiency of unloading and to car bottle liquid feeding further.
As shown in Figure 2, in the present embodiment, pressurized machine 5 has supercharging muffler 50 and supercharging liquid-phase tube 51.One end of supercharging muffler 50 is communicated in gas returning port 31 of unloading.In addition, supercharging muffler 50 is also communicated in the gas phase pipe 14 of basin 1, that is, it is communicated with inner container 11 by gas phase pipe 14.One end of supercharging liquid-phase tube 51 is communicated in boost port 30 of unloading, and in addition, supercharging liquid-phase tube 51 is also communicated in immersed pump 41, same, and above connectivity structure also realizes by existing valve and associated conduit, but not as limit.
As shown in Figure 2, each filling machine 2 all has filling machine muffler 20 and filling machine liquid-phase tube 21.Filling machine muffler 20, by the supporting pipeline 7 of connection one, is communicated with top liquid inlet pipe 13 and bottom liquid inlet pipe 12.Filling machine liquid-phase tube 21, by connection one drain pipe 8, is communicated with supercharging liquid-phase tube 51 and immersed pump 41.Above connectivity structure realizes by existing valve and associated conduit, but not as limit.
In addition, as shown in Figure 2, supporting pipeline 7 is communicated with by a balance tube 78 with between drain pipe 8.In order to the liquid backflow that will residue in after filling machine 2 pairs of car bottle liquid feedings in drain pipe 8 and filling machine liquid-phase tube 21 to inner container 11.
As shown in Figure 2, safe diffusion system 6 comprise safety diffuse pipeline 60, heater 61 and blow-down pipe 62.Heater 61 diffuses pipeline 60 by safety and is communicated in gas phase pipe 14, that is, be communicated in inner container 11 by gas phase pipe 14, in order to emptying gas after the heating when basin 1 pressure reaches opening pressure of safety valve.Heater 61 can select EAG (Escape Air Gas) heater 61, but not as limit.Blow-down pipe 62 is communicated with heater 61, in order to discharge the emptying gas after heater via 61 heating.
In the present embodiment, this skid-mounted gas filling station carries out in the factory assembling and debugs, be transported to job site afterwards to be fixed on the ground by securing parts such as such as fixing bolts or on working platform, can come into operation immediately, its major function that can realize is, carries out supercharging, unloads and carry out liquid feeding to car bottle to tank car.
In the present embodiment, before unloading, if tank car internal pressure is less than or equal to basin 1 pressure, by the setting of pressurized machine 5 and associated pipe, supercharging is carried out to tank car.Be specially, after tank car enters, liquid in tank car enters pressurized machine 5 by boost port 30 of unloading by supercharging liquid-phase tube 51, pressurized machine 5 is gasificated as gas to this heating liquid supercharging, this gas is got back in tank car by supercharging muffler 50 by gas returning port 31 of unloading afterwards, make the pressure in the storage tank of tank car be greater than the pressure of basin 1, namely complete the supercharging to tank car.After completing tank car supercharging, or when tank car internal pressure has originally been greater than basin 1 internal pressure, the liquid in tank car enters in inner container 11 by liquid phase mouth 32 of unloading by top liquid inlet pipe 13 and bottom liquid inlet pipe 12 equably, namely realizes the function of unloading.
When to car bottle liquid feeding, need the pressure adjusting car bottle inside equally, that is, need the pressure adjusting of car bottle inside to the pressure being less than basin 1.Specifically, after car bottle is communicated with filling machine 2, the gas in car bottle is entered in inner container 11 by filling machine muffler 20, reaches the function to car bottle pressure release, to make the liquid in basin 1 pass more readily filling machine 2 enter car bottle.In addition, when basin 1 internal pressure is lower than respective standard, such as, during lower than 0.4MPa, need further to basin 1 supercharging, now can open supercharging liquid-phase tube 51, utilize immersed pump 41 that liquid in inner container 11 is pumped into pressurized machine 5 by supercharging liquid-phase tube 51, pressurized machine 5 pairs of liquid carry out supercharging gasification for after gas, and gas gets back to content wherein by supercharging muffler 50 by gas phase pipe 14 again.After car bottle internal pressure is less than basin 1 pressure, can start to carry out liquid feeding to car bottle.Specifically, the supercharging liquid-phase tube 51 opened before closedown, the liquid afterwards in inner container 11 is pumped in filling machine 2 by drain pipe 8 by immersed pump 41, then is filled with car bottle by filling machine 2, completes the liquid feeding to car bottle.In addition, after car bottle liquid feeding, open balance tube 78, the liquid remained in pipeline is got back in inner container 11 via balance tube 78.
In addition, when basin 1 internal pressure is too high, need to carry out pressure release to basin 1.That is, the gas in inner container 11 enters safe diffusion system 6 by gas phase pipe 14 and discharges.Specifically, when inner container 11 overpressure of basin 1, pressurized gas in inner container 11 diffuse pipeline 60 by gas phase pipe 14 by safety and enter heater 61, and these gases discharge emptying by blow-down pipe 62 after being heated by heater 61, namely complete the pressure release to basin 1.
Though exemplary embodiment describe skid-mounted gas filling station of the present invention with reference to several, should be understood that term used be illustrate and illustrative, and not restrictive.Its design or essence is not departed from because the present invention can specifically implement in a variety of forms, therefore, above-described embodiment is not limited to any aforesaid details, and explain widely in the design that should limit in claim of enclosing and scope, therefore the whole change fallen in claim or its equivalent scope and remodeling all should be claim of enclosing and contained.
