Abstract
A kind of LNG cold recoveries system, including the gas pipeline of LNG storage tank and connection LNG storage tank, the gas pipeline are equipped with air temperature type vaporizer, and the gas pipeline is equipped with heat exchanger in air temperature type vaporizer upstream, and heat exchanger is connected with medium circulation pipeline.The utility model provides a kind of LNG cold recoveries system, and using coolant media and liquefied natural gas heat exchange, coolant media is liquefied by heat exchange cooling, and pipe network after liquefied natural gas vaporization re-heat, recycles the cold of coolant media as the low-temperature receiver of other gases.
Description
Technical field
The utility model belongs to gas cold energy recovery technology field, refers in particular to a kind of LNG cold recoveries system.
Background technology
Hydrogen manufacturing project removes device for producing hydrogen after using liquefied natural gas vaporization, is vaporized in way using air temperature type vaporizer and the external world
Air heat-exchange, about 100 tons of cold is lost in its liquefied natural gas in vain daily.
Utility model content
The purpose of this utility model is to provide a kind of LNG cold recoveries system, using coolant media and liquefied natural gas heat
Exchange, coolant media is liquefied by heat exchange cooling, and pipe network after liquefied natural gas vaporization re-heat, recycles the cold conduct of coolant media
The low-temperature receiver of other gases.
What the purpose of this utility model was realized in：A kind of LNG cold recoveries system, including LNG storage tank and connection LNG
The gas pipeline of storage tank, the gas pipeline are equipped with air temperature type vaporizer, and the gas pipeline is in air temperature type vaporizer upstream
Equipped with heat exchanger, heat exchanger is connected with medium circulation pipeline.
Preferably, the medium circulation pipeline is equipped with compressor and valve.
Preferably, the air temperature type vaporizer downstream is equipped with valve.
Preferably, the gas pipeline connection CNG gas transmission pipeline net works.
Preferably, the medium circulation pipeline is equipped with temperature display, for controlling heat exchanger refrigerant to pass in and out temperature.
Compared with prior art, the beneficial effects of the utility model are:The cold of LNG is recycled by heat exchanger,
So that the operational outfit liquid such as space division air compressor machine, circulator energy consumption declines, energy consumption is saved.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1：
A kind of LNG cold recoveries system, includes the gas pipeline of LNG storage tank and connection LNG storage tank, on the gas pipeline
Equipped with air temperature type vaporizer, the gas pipeline is equipped with heat exchanger in air temperature type vaporizer upstream, and heat exchanger is connected with refrigerant circulation
Pipeline.
Preferably, the medium circulation pipeline is equipped with compressor and valve.
Preferably, the air temperature type vaporizer downstream is equipped with valve.
Preferably, the gas pipeline connection CNG gas transmission pipeline net works.
Preferably, the medium circulation pipeline is equipped with temperature display, for controlling heat exchanger refrigerant to pass in and out temperature.
Liquefied natural gas fades to room temperature hydrogen manufacturing by low temperature, its tank outlet to air temperature type vaporizer middle is increased and is exchanged heat
Device, using coolant media and liquefied natural gas heat exchange, coolant media is liquefied by heat exchange cooling, after liquefied natural gas vaporization re-heat
CNG gas transmission pipeline net works are removed, recycle the cold of coolant media as the low-temperature receiver of other gases.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
Enclose, therefore：The equivalence changes that all structures, shape, principle according to the utility model are done, should all be covered by the protection of the utility model
Within the scope of.
