Description
Technical field
The utility model relates to gasification pressure regulation field, to gasify voltage-regulating system in particular to a kind of gas station LNG.
Background technique
LNG tank car is the means of existing transport LNG, transports LNG to LNG supply station from area of origin.Need first LNG tank car to be unloaded liquid to LNG storage tank at unloading deck in the technological process of tradition LNG vaporizing station, again the LNG in LNG storage tank is gasified, unload after operating, also to have a surplus in tank car liquid residual air, a wherein part can be extracted and recycle, but recovering effect is unsatisfactory, profit is not significantly improved.There is the problem that increment gas price is high current gas company, and therefore the profit margin of gas station is very limited.
Combustion gas is popularized in the life of masses, when not reaching balance with gas and air feed, the source of the gas of pipeline is nervous, and the pressure of pipe network sharply declines naturally, thus cause gas station compressor normally to start, need to wait until that sufficient combustion gas arrives, when ductwork pressure is replied normal, gas station could normally run, thus, the work of gas station and the life of people are brought inconvenience, economically, causes certain economic loss.
Summary of the invention
The utility model aims to provide a kind of gas station LNG and to gasify voltage-regulating system, the problem that during to solve that profit margin reduces, CNG source of the gas is under-supply, gas station can not normally run.
A kind of gas station LNG gasifies voltage-regulating system, and comprise LNG tank car, described LNG tank car is in series with gasification installation, pressure governor and flowmeter successively by pipeline, and described flowmeter is connected with CNG compressor, and described CNG compressor connects CNG air cylinder group.
Further, described gasification installation comprises empty temperature vaporizer and water-bath heater.
Further, described LNG tank car connects described sky temperature vaporizer, and described sky temperature vaporizer connects water-bath heater, and described water-bath heater connects pressure governor.
It can thus be appreciated that, the utility model has the advantage of: the utility model structure is simple, by being provided with gasification installation, the liquid phase gas gasification of LNG tank car is become gaseous gas, improves the economic benefit of CNG gas station, and when source of the gas is nervous, emergent CNG source of the gas is provided, ensures that gas station normally runs.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Embodiment
The problem that gas station profit reduces in order to solve, CNG source of the gas affect the operation of CNG gas station time under-supply, now provides a kind of gas station LNG to gasify voltage-regulating system.
Below in conjunction with the accompanying drawing in the utility model, be clearly and completely described the technological scheme in the utility model, obviously, that described is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, belongs to the scope of the utility model protection.
As shown in Figure 1, a kind of gas station LNG gasifies voltage-regulating system, comprise LNG tank car 1, described LNG tank car 1 is in series with gasification installation, pressure governor 4 and flowmeter 5 successively by pipeline, and described flowmeter 5 is connected with CNG compressor 6, and described CNG compressor 6 connects CNG air cylinder group 7, described gasification installation comprises empty temperature vaporizer 2 and water-bath heater 3, described LNG tank car 1 connects described sky temperature vaporizer 2, and described sky temperature vaporizer 2 connects water-bath heater 3, and described water-bath heater 3 connects pressure governor 5.
Below list preferred embodiment of the present utility model, to understand advantage of the present utility model better:
Embodiment one:
After LNG tank car 1 completes and unloads liquid, pressure in tank car is generally 0.2MPa-0.6MPa, liquid residual air more than tank car is extracted, until when tank car internal pressure is 0.1MPa, stopping is bled, can utilize empty temperature vaporizer 2 and water-bath heater 3 that liquid residual air more than tank car is carried out gasification operation, the LNG of low temperature enters empty temperature vaporizer 2, with be converted into gaseous natural gas after air heat-exchange and raised temperature, also very low from sky temperature vaporizer 2 natural gas temperature out, need to be heated up by water-bath heater 3, through pressure governor 4, pressure regulation is carried out to the complete combustion gas of gasification, by flowmeter 5 before the combustion gas of pressure regulation enters CNG compressor 6, gas quantity can be counted, CNG compressor 6 shortens CNG into gas pressure, enter CNG air cylinder group 7, sell again.The remaining liquid residual air that this kind of mode makes gas station can reclaim tank car is as best one can sold, and profit is high, improves the economic benefit of LNG gas station;
Embodiment two:
Due to the problem that gas company's ubiquity increment gas price is high, when LNG price differential height, LNG can be bought, LNG tank car 1 connects overhead temperature vaporizer 2 and water-bath heater 3, the LNG of tank car is gasified, the LNG of low temperature enters empty temperature vaporizer 2, with be converted into gaseous natural gas after air heat-exchange and raised temperature, also very low from sky temperature vaporizer 2 natural gas temperature out, need to be heated up by water-bath heater 3, through pressure governor 4, pressure regulation is carried out to the complete combustion gas of gasification, by flowmeter 5 before the combustion gas of pressure regulation enters CNG compressor 6, gas quantity can be counted, CNG compressor 6 shortens CNG into gas pressure, enter CNG air cylinder group 7, use as increment gas, because LNG price differential is higher, improve profit margin,
Embodiment three:
When CNG source of the gas is nervous, the pressure of grid can sharply decline, when gas station inner compressor cannot start, LNG tank car 1 connects empty temperature vaporizer 2 and water-bath heater 3, the LNG of tank car is gasified, the LNG of low temperature enters empty temperature vaporizer 2, with be converted into gaseous natural gas after air heat-exchange and raised temperature, also very low from sky temperature vaporizer 2 natural gas temperature out, need to be heated up by water-bath heater 3, through pressure governor 4, pressure regulation is carried out to the complete combustion gas of gasification, by flowmeter 5 before the combustion gas of pressure regulation enters CNG compressor 6, gas quantity can be counted, CNG compressor 6 shortens CNG into gas pressure, enter CNG air cylinder group 7, can be used as supplementary source of the gas, compressor is normally worked, ensure the normal operation of gas station, reduce economic loss.
From the above, advantage of the present utility model has: the utility model structure is simple, by being provided with gasification installation, the liquid phase gas gasification of LNG tank car is become gaseous gas, improve the economic benefit of CNG gas station, and when source of the gas is nervous, provide emergent CNG source of the gas, ensure that gas station normally runs, reduce economic loss.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
