Description
Technical field
The utility model relates to LNG filing provision field, specifically a tank one pump two machine LNG filling station.
Background technique
Conventional LNG filling station build the place of natural gas line process in, and directly get gas from natural gas line, rock gas, through the technique such as desulfurization, dehydration, enters compressor and compresses, and then enters gas selling machine to vehicle aerating.This kind of filling station is comparatively strong to gas distributing system dependence, must build the place of natural gas line process in, cause cost high, and floor space is large, and the construction period is long.
Summary of the invention
The tank one pump two machine LNG filling station that not enough for above-mentioned prior art, the utility model provides a kind of and takes up an area less, safety, maintenance are easy to assembly, cost-saving.
The tank one pump two machine LNG filling station that the utility model provides is achieved through the following technical solutions:
One tank one pump two machine LNG filling station, comprise LNG pump sled 1, LNG storage tank connection sled 2, low-temperature storage tank 3, LNG vaporizer prying body 4, LNG liquid addition machine (5a, 5b), control cabinet 6, it is characterized in that: LNG pump sled 1 is connected sled 2 by metallic hose with LNG storage tank and connects, LNG storage tank is connected sled 2 and is connected with low-temperature storage tank 3 and LNG vaporizer prying body 4 respectively by metallic hose, and LNG pump sled 1 is connected with LNG liquid addition machine (5a, 5b) respectively by metallic hose.
Described LNG vaporizer prying body 4 is integral type structure, comprises EAG heater 41 and pressurized machine 42, is arranged on below low-temperature storage tank.
Described low-temperature storage tank 3 is horizontal cylinder shape cryogenic vacuum powder isolation storage tank, and long 14 meters of tank, external diameter 3 meters, volume is 60 cubic metres, net weight 28.5 tons.
The beneficial effects of the utility model are:
1. adopt skid-mounted structure, do not rely on gas distributing system, maneuverability, take up an area few, only need deliver LNG as source of the gas with LNG tank car, applied widely.
2, do not need natural gas purification equipment and air compressor in complete equipment, greatly reduce auxiliary facility, not only saved equipment manufacturing cost, and shortened the construction period.
3, increase storage tank and connect sled, and pipeline to be optimized, to safeguard easy to assembly, more safe, environmental protection, low energy consumption.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: LNG pump sled 1, LNG storage tank connect sled 2, low-temperature storage tank 3, LNG vaporizer prying body 4, EAG heater 41, pressurized machine 42, LNG liquid addition machine (5a, 5b), control cabinet 6, LNG tank car 7.
Embodiment
A tank one pump two machine LNG filling station as shown in Figure 1, comprise LNG pump sled 1, LNG storage tank connection sled 2, low-temperature storage tank 3, LNG vaporizer prying body 4, LNG liquid addition machine (5a, 5b), control cabinet 6, it is characterized in that: LNG pump sled 1 is connected sled 2 by metallic hose with LNG storage tank and connects, LNG storage tank is connected sled 2 and is connected with low-temperature storage tank 3 and LNG vaporizer prying body 4 respectively by metallic hose, and LNG pump sled 1 is connected with LNG liquid addition machine (5a, 5b) respectively by metallic hose.LNG vaporizer prying body 4 is integral type structure, comprises EAG heater 41 and pressurized machine 42, is arranged on below low-temperature storage tank.Low-temperature storage tank 3 is horizontal cylinder shape cryogenic vacuum powder isolation storage tank, and long 14 meters of tank, external diameter 3 meters, volume is 60 cubic metres, net weight 28.5 tons.
To unload flow process: after LNG tank car 7 arrives at a station, pressurized machine 42 pairs of tank car 7 storage tanks are utilized to boost, after making to form certain pressure reduction between LNG tank car 7 and low-temperature storage tank 3, the LNG in LNG tank car 7 unloads in inbound interior low-temperature storage tank 3 by the liquid pipeline that unloads between opening vehicle, tank.Also can select to start the immersed pump in LNG pump sled 1, the LNG in LNG tank car 7 be unloaded in inbound interior low-temperature storage tank 3 and store.
Automobile liquid feeding flow process: the saturated LNG in low-temperature storage tank 3 passes through liquid feeding rifle on liquid filler (5a, 5b) to automobile liquid feeding afterwards by the metering of the immersed pump pressurization in LNG pump sled 1 and liquid filler (5a, 5b).
