A kind of multi-functional LNG bottle group fills one sled
Technical field
The utility model belongs to LNG filing provision technical field, particularly relates to a kind of multi-functional LNG bottle group and fills one sled.
Background technique
Along with the development of globalization of World Economics; the status expanding day of rock gas in energy resource structure; the novel environment friendly energy of 21 century; accelerate to utilize rock gas and city gas gasification to uplifting the people's living standard; reduce pollution of atmosphere, strengthen environmental protection, improve city grade; improve the investment climate, have positive effect.Clean as one, the efficient emerging energy of LNG, obtains and applies comparatively widely.Along with the development of China LNG automobile industry, its advantage highlights day by day, but due to LNG gas station website fixing at present few, can not meet the actual demand of LNG refueling, and function singleness.In addition, the channelization of city gas supply is the inexorable trend of urban development, but when pipeline network of fuel gas in city construction can not get the ample supply of upstream source of the gas unit, especially the area of gas supply is badly in need of when building vaporizing station and still not possessing corresponding conditions in city, will bring inconvenience to residential quarters or user.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of multi-functional LNG bottle group simple and compact for structure, that design science is reasonable, with low cost, esy to use, safe and reliable to fill one sled, can effectively by several functions skid in a shipping container, floor space is little, not only can give refueling but also can resident's air feed be given, practical.
The technical solution adopted in the utility model is:
A kind of multi-functional LNG bottle group fills one sled, it is characterized in that: comprise chassis, be arranged on the low temperature immersed pump on described chassis, low temperature steel cylinder, bus dump, empty warm vaporizer, LNG filling machine, water-bath type electric heater, pressure regulation metering system and control system, the outlet of described low temperature immersed pump by described bus dump respectively with described low temperature steel cylinder, described LNG filling machine connects, described sky temperature vaporizer is connected with described low temperature steel cylinder by described bus dump, described water-bath type electric heater, described sky temperature vaporizer, described pressure regulation metering system connects successively, on the support frame of described set-up of control system above described sky temperature vaporizer, described low temperature immersed pump, described low temperature steel cylinder, described sky temperature vaporizer, described LNG filling machine, described pressure regulation metering system is provided with valve each other.
Further, described pressure regulation metering system comprises flowmeter, piping filter and decompression regulating valve, connects successively between described decompression regulating valve, described piping filter, described flowmeter.
Further, the base of described low temperature steel cylinder is arranged with electronic scale, for judging the number of liquid in low temperature steel cylinder.
Further, when the LNG in described low temperature steel cylinder uses up, can directly from the outside in transfer of cryogenic steel cylinder and sled empty low temperature steel cylinder exchange and use, simple to operation.
The beneficial effects of the utility model are: the utility model both can realize being filled in low temperature steel cylinder by low temperature immersed pump by LNG, also by being filled in low temperature steel cylinder by LNG after empty temperature vaporizer vaporization supercharging, can decrease the frequency of utilization of immersed pump; LNG can be flowed to filling machine and low temperature steel cylinder by the utility model simultaneously, realizes the function of unloading and aerating is synchronous; By sky temperature vaporizer and pressure regulation metering system, the pressure required for pressure regulation to user, then supplies user and uses, when temperature is lower in the winter time, first can pass through water-bath type electric heater, through sky temperature vaporizer and pressure regulation metering system, then supply user and use; The utility model is simple and compact for structure, design science is reasonable, have and different fill function, realization is unloaded synchronous with aerating, there is pressure regulation metering function simultaneously, not only can give refueling but also can realize for resident, with low cost, esy to use, safe and reliable, can air feed on the spot, air feed is convenient, flexible, has vast potential for future development.
