Background technique
Hydrogen Energy is considered to the important secondary energy of new century with outstanding advantages such as its transformation efficiency height, products of combustion cleaning and purposes variations.It is the important component part of hydrogen economy that the economical and efficient of economic scale hydrogen manufacturing, safe and reliable transmission ﹠ distribution hydrogen, hydrogen is used.Wherein, economic, efficient, safe hydrogen storage technology is the key that practicability is moved towards in the Hydrogen Energy utilization, become international research focus, " National Program for Medium-to Long-term Scientific and Technological Development (2006-2020) " of China also classifies it as the important development direction.
In order to satisfy the practical requirement in the actual production life, present existing hydrogen storage technology, comprise high-pressure hydrogen storing, liquid hydrogen accumulating, hydride hydrogen-storing, complex metal hydride storage hydrogen, active carbon cryogenic absorption storage hydrogen, CNT storage hydrogen, liquid organic hydride Chu Qing etc., none can satisfy actual hydrogen storage content fully and require index.
At present, the storage hydrogen mode that is most possibly applied in a large number on the practical fields such as hydrogen energy automobile is high-pressure hydrogen storing and hydride hydrogen-storing.Wherein, hydrogen storage structure is simple owing to having for high-pressure hydrogen storing, quality hydrogen-storage density height, fill with outstanding advantages such as mass rate of emission are fast and enjoy attention, but, because danger that the High Pressure Hydrogen device is potential and people exist the psychology of high pressure hydrogen is feared, the popularization on a large scale of this class storage mode at present still is subjected to great resistance.On the other hand, though hydride hydrogen-storing has the good advantage of Security, also exist the low and speed for hydrogen absorbing and releasing of weight hydrogen-storage density to control comparatively shortcoming such as complexity at present.
Because hydrogen bearing alloy is inhaled and to be put the hydrogen process and have remarkable thermal effect, heat release when inhaling hydrogen, and absorbing heat when putting hydrogen, and suction, thermal discharge are very big, so the structural design of metal hydride hydrogen storage unit is answered in the assurance device smoothness of effectively heat exchange and flow hydrogen gas.The thermal conductivity of hydrogen-bearing alloy powder is generally lower, for the temperature conductivity that improves hydrogen-bearing alloy powder bed body and the heat exchange inside and outside the reinforced device, generally, in hydrogen-bearing alloy powder, add a certain proportion of Heat Conduction Material simultaneously by have the heat exchanger components of a fixed structure in the device positioned inside.Chinese patent ZL 200620045788.1 provides a kind of coil exchanger that utilizes, when filling hydrogen, lower the temperature, the device that heats during release hydrogen, but this device is provided with heat exchange pipeline has very big installation, difficulty of processing, and in use complicated heat exchange structure also can reduce the Security of hydrogen-storing device.Chinese patent utility model patent ZL200520127709.1 does not have effective means by reaching finned between reservoir vessel and the frame shell between the reservoir vessel but hydrogen is put in heating.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes deficiency of the prior art, and a kind of heat self-balancing metal hydride hydrogen storage device is provided.
For solving the problems of the technologies described above, solution provided by the invention is:

Beneficial effect of the present invention is:
The present invention has avoided installing complicated heat exchanger, heat exchange pipeline and external water temperature adjusting and heating equipment in hydrogen storage vessel, avoided installing the risk that built-in pressure piping causes, and the recycling heat that adds hot hydrogen has reached energy-conservation, efficient, purpose of safety.
Description of drawings
Fig. 1 is the heat self-balancing metal hydride hydrogen storage device schematic representation.
Fig. 2 is an accumulation of heat capsule structure schematic representation
Reference character is: hydrogen outlet 1, hydrogen storage vessel flange end socket 2, flange end socket junction surface 3, accumulation of heat capsule 4, support 5, hydrogen storage metal powder 6, ventilative stock column 7, heat-conducting metal shell 8, modified paraffin 9,10 thermal insulation layers.
Embodiment
The invention will be further described below with reference to accompanying drawing and example.
A kind of heat self-balancing metal hydride hydrogen storage device is provided, comprises a hydrogen storage vessel, the wall of hydrogen storage vessel is that metal or composite material are made, its outer wrap the thermal insulation layer 10 of thermoinsulation material carry out exchange heat to prevent internal tank and outside.The inside of described hydrogen storage vessel is provided with some hollow ventilative stock columns 7, and ventilative stock column 7 is fixing by support 5, and support 5 is connected on the hydrogen storage vessel inwall.
On the wall of ventilative stock column 7 air hole is set, its inside is filled with the mixture of hydrogen storage metal powder 6 and accumulation of heat capsule 4, hydrogen storage metal powder 6 mixes by specific volume ratio with accumulation of heat capsule 4, this ratio should be required according to the heat self-balancing of hydrogen storage metal powder amount of stored heat difference, need satisfy the accumulation of heat capsule has enough amount of stored heat, and possesses certain allowance.Accumulation of heat capsule 4 and hydrogen storage metal powder 6 are mixed, just can guarantee between the two, to have enough big area of contact and higher heat transfer efficiency.The overall dimensions of accumulation of heat capsule 4 (diameter or length) is no more than 1/5 with the ratio of stock column diameter, and the size of capsule is more little, and its area of contact is big more, and the heat exchange effect will be good more.
Described accumulation of heat capsule 4 has the shell that aluminium or copper are equipped with, and has certain intensity, can avoid mixing with hydrogen bearing alloy after paraffin (or other heat storage medium) melted by heat, has a strong impact on the suction hydrogen meter area and the hydrogen sucking function of hydrogen bearing alloy; Heat storage medium modified paraffin 9 is filled in its inside, can certainly select other heat storage medium for use.
The present invention proposes the notion of heat self-balancing, by in hydrogen storage material, sneaking into the capsule that specific surface area is big, modified paraffin (or other heat storage medium) composite phase-change material of good effect of heat exchange is made by a certain percentage, the heat of being emitted when utilizing this material absorption hydrogen bearing alloy to inhale hydrogen, and when putting hydrogen, this heat is offered hydrogen bearing alloy, realize that hydrogen bearing alloy is inhaled, the temperature when putting hydrogen is controlled and energy balance.
The present invention adopts the hydrogen-storing device that (20MPa is following) metal hydride and pressure storage hydrogen combine under the mesolow, comprehensive two kinds of storage hydrogen modes advantage separately, thereby under the situation that guarantees safety, can improve hydrogen storage density to a great extent again, in the hope of the economy that realizes hydrogen, efficient, safe storage.
In addition at the hydrogen storage vessel of movable type, for metal powder granulates and capsule are kept in touch, and be unlikely to take place tangible segregation phenomenon at the volley, so need design and installation support and ventilative module exterior package, according to the difference of pressure rating, different designs is arranged, accompanying drawing 1 is depicted as the structural representation of pressure when relatively low, wherein the material of ventilative stock column 7 can prevent that particle from exposing, but can guarantee that hydrogen sees through.
At last, it is also to be noted that what more than enumerate only is specific embodiments of the invention.Obviously, the invention is not restricted to above embodiment, many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
