Abstract
The present invention discloses a liquid hydrogen nondestructive storage system based on low-temperature refrigerator. It includes the following several portions: liquid hydrogen storage tank, steam outlet pipe, hydrogen gas heat-exchanger, low-temperature refrigerator and liquid reflux pipe. Said invention also provides the connection mode of all the above-mentioned portions.
Description
Technical field
The present invention relates to a kind of lossless system for storing liquid hydrogen, be applicable to the long term storage of liquid hydrogen in storage tank based on Cryo Refrigerator.
Background technique
Hydrogen Energy will be the important energy source of 21 century.As one of main storing mode of hydrogen, liquid hydrogen has great application prospect.Liquid hydrogen storing unit mass storage hydrogen density and unit bodies repertory hydrogen density height, near the practicability target call, and in the contour sciemtifec and technical sphere acquisition extensive use of space flight department.Compare with high pressure hydrogen with hydrogen bearing alloy, under identical storage weight, the volume minimum that liquid hydrogen stores, container weight and gross weight are also minimum.The major defect of liquid hydrogen storing is because liquid hydrogen evaporates the heat leakage problem that causes, and the device structure complexity, and it is higher that liquid hydrogen is produced cost, and safety technique is more complicated also.
During liquid hydrogen stored, the heat leakage problem was particularly outstanding.The liquid hydrogen boiling point is very low and the latent heat of vaporization is little, and heat is easy to be infiltrated and caused liquid hydrogen boiling vaporization and lose by the external world.The storage tank that short time stores liquid hydrogen is uncovered, allows a small amount of evaporation to keep low temperature.Even but adopting the vacuum insulation storage tank, liquid hydrogen also is difficult to long-time the storage.Because the heat leakage problem is inevitable, always have the liquid hydrogen gasification in the liquid hydrogen storage process, cause the storage tank internal pressure constantly to increase.When pressure is increased to certain value, just must starts safety valve and discharge hydrogen, thereby cause the waste of the energy.Simultaneously, hydrogen is inflammable and explosive, handles vaporized gas and need set up auxiliary safety measure.In addition, the direct discharging of hydrogen also may damage environment.
Cryo Refrigerator has moved towards commercialization and practicability gradually.G-M refrigerator, sterlin refrigerator, vascular refrigerator all can reach liquid hydrogen temperature, and at the 20K warm area certain refrigerating capacity are arranged, and can be used for the hydrogen that liquefies.
Summary of the invention
The purpose of this invention is to provide a kind of lossless system for storing liquid hydrogen based on Cryo Refrigerator.Utilize the hydrogen again condensation recovery of Cryo Refrigerator with evaporation, the heat leakage of compensation storage tank, thus can prolong the emptying cycle of storage tank or the long-term harmless storage of realization liquid hydrogen.
It comprises liquid hydrogen storage tank, steam introduction pipe, hydrogen heat exchanger, Cryo Refrigerator, liquid return pipeline, liquid hydrogen storage tank top is provided with steam introduction pipe, liquid return pipeline, hydrogen heat exchanger two ends join with steam introduction pipe, liquid return pipeline respectively, and hydrogen heat exchanger top is connected with the cool end heat exchanger of Cryo Refrigerator.
The present invention has avoided the waste of hydrogen energy source with the hydrogen condensation recovery again of evaporating owing to leakage heat in the liquid hydrogen storage tank.And this system uses equipment such as conventional liquid hydrogen storage tank, can transform easily on original storage tank, invest little, simple in structure, easy to operate, economic benefit is high, can be widely used in the liquid hydrogen storage tank of large, medium and small scale.
Description of drawings
Accompanying drawing is based on the lossless system for storing liquid hydrogen structural representation of Cryo Refrigerator, among the figure: liquid hydrogen storage tank 1, steam introduction pipe 2, hydrogen heat exchanger 3, Cryo Refrigerator 4, liquid return pipeline 5.
Embodiment
As shown in drawings, lossless system for storing liquid hydrogen based on Cryo Refrigerator comprises liquid hydrogen storage tank 1, steam introduction pipe 2, hydrogen heat exchanger 3, Cryo Refrigerator 4, liquid return pipeline 5, liquid hydrogen storage tank 1 top is provided with steam introduction pipe 2, liquid return pipeline 5, hydrogen heat exchanger 3 two ends join with steam introduction pipe 2, liquid return pipeline 5 respectively, and hydrogen heat exchanger 3 tops are connected with the cool end heat exchanger of Cryo Refrigerator 4.
Described Cryo Refrigerator 4 is vascular refrigerator, sterlin refrigerator or GM refrigerator.Hydrogen heat exchanger 3 is the finned cryogenic heat exchanger of compact type, compact type vertical row tubular type cryogenic heat exchanger or compact type coil pipe type cryogenic heat exchanger.The liquid hydrogen storage tank is large, medium and small conventional storage tank
The condensate recovery system again of evaporation hydrogen in the liquid hydrogen storage tank of the present invention, the hydrogen of evaporation is drawn by the storage tank top in the liquid hydrogen storage tank, through the steam introduction pipe hydrogen heat exchanger of flowing through, cool end heat exchanger by Cryo Refrigerator is condensed into liquid, get back to the liquid hydrogen storage tank through the liquid return pipeline again, thereby circulation is reclaimed in the condensation again of having finished evaporation hydrogen.
Embodiment 1
In the present embodiment, liquid hydrogen storage tank 1 is small-sized liquid hydrogen storage tank, and evaporation hydrogen condensation again institute chilling requirement is not higher than the refrigerating capacity that Cryo Refrigerator 4 is had at the liquid hydrogen warm area.The work of design separate unit refrigerator, can make in the storage tank evaporation hydrogen all again condensation reclaim, avoided the emptying of hydrogen, thereby realized long-term harmless storage of liquid hydrogen.
In the present embodiment, liquid hydrogen storage tank 1 is medium-sized or large-scale liquid hydrogen storage tank, and the evaporation hydrogen all institute of condensation again chilling requirement is higher than the refrigerating capacity that Cryo Refrigerator 4 is had at the liquid hydrogen warm area.If the work of design separate unit refrigerator can reduce evaporation of liquid rate in the storage tank, reduce storage tank pressure, thereby can prolong the emptying cycle of hydrogen.If many refrigerators of design are worked simultaneously, make the refrigerating capacity of refrigerator can reach the evaporation hydrogen required whole colds of condensation again, so just can solve the heat leakage problem of liquid hydrogen storage tank, the harmless storage of liquid hydrogen of realizing big-and-middle-sized storage tank so that the liquid hydrogen relative evaporation vanishing that stores.
