Description
Technical field
The present invention relates to the metal hydride hydrogen-storing device of a kind of flexible structure, based on solid-state hydrogen storage technology, it is achieved that low-voltage safety hydrogen storage, belong to the storage of hydrogen, transport and supply field.
Background technology
Hydrogen Energy is a kind of generally acknowledged cleaning secondary energy sources, and its research, development and utilization are just being subject to increasingly paying attention to widely.Owing to hydrogen quality is little, in gaseous state under room temperature, inflammable and explosive, there is again during as fuel dispersibility and be interrupted the feature used, therefore the storage of hydrogen is the key issue utilizing Hydrogen Energy on a large scale.Based on the metal hydride hydrogen-storing device of solid-state hydrogen storage technology, being successfully applied to fuel cell, gas chromatograph, hydrogen atomic clock etc. needs the field of high-purity hydrogen source.
The patent that current metal hydride hydrogen-storing device is relevant, its container material all adopts the alloy material such as rustless steel, aluminium alloy, and profile mostly is cylindrical structural, there is the problems such as structure is single, weight is big.Patent of the present invention provides the metal hydride hydrogen-storing device of a kind of flexible structure, and profile is changeable, strong adaptability, lightweight, it is adaptable to the applications such as field analysis, outdoor travel, Pan Shan, military affairs.
Summary of the invention
For problem above, the present invention provides the metal hydride hydrogen-storing device of a kind of flexible structure, the composite using multilamellar forms outer package, this packaging has necessarily pressure, heatproof, gas barrier properties, use platform forces down, delayed little hydrogen bearing alloy, reduce further and use pressure, be furnished with relief valve, it is ensured that the stability that hydrogen storage device uses for a long time.
The technical solution adopted in the present invention is: provide the metal hydride hydrogen-storing device of a kind of flexible structure, there is the outer package that multilayer materials is made, this material has necessarily pressure, heat-resisting and good heat conductivility, and there is excellent air-tightness, guarantee that hydrogen, oxygen, nitrogen, empty gas and water, wet goods cannot pass through, platform is pressed relatively low hydrogen storing alloy powder fill in inside, the air inlet/outlet of hydrogen storage device is equipped with valve, hydrogen can pass through air inlet/outlet and enter inside hydrogen storage device, hydrogen storage device, equipped with relief valve, keeps internal pressure less than setting value.
The multilayer materials that material used by outer package is made up of PET, NY, PE, metal forming etc., this outer package is pressure is not less than 0.2MPa, and heatproof is not less than 50 DEG C.
Metal foil material in multilayer materials is aluminum, copper or alloy, and wherein layer of metal paper tinsel is positioned at innermost layer, and metal forming may be connected to outside hydrogen storage device, is beneficial to the heat exchange that hydrogen storage device is internal and extraneous.
Hydrogen storing alloy powder used is lanthanon hydrogen storage alloy powder or titanium base hydrogen storage alloy powder, inhales hydrogen platform pressure for its 25 DEG C and is not less than 0.2MPa, puts hydrogen platform pressure not higher than 1.0MPa for 25 DEG C.
Safety valve setting pressure used is not less than 0.2MPa, when because of accidental operation, environmental change etc. so that when internal pressure is higher than setting value, relief valve automatically turns on pressure release, and when in hydrogen storage device, pressure is lower than this setting value, relief valve cuts out, make hydrogen storage device and external environment, continue to keep air-tight state.
The invention have the advantages that (1) simple in construction, lightweight, packaging material use lighter composite, greatly reduce the weight of hydrogen storage device.(2) shape variable, may be designed to rectangle, cylinder, elliposoidal, flat build etc., easy to carry.(3) metal foil layer can strengthen the heat exchange of internal material and external environment, the shortcoming that when improving composite as outer package, heat conductivility is not good.(4) using low platform pressing gold, normal use pressure relatively conventional hydrogen storage device product is lower, uses relief valve, makes product low-voltage safety.
