Description
Technical field
The present invention relates to a kind of fuel cell cogeneration, in particular, relate to a kind of fuel cell cogeneration that is applicable to and entirely twine hydrogen storage cylinder with little volume hydrogen aluminum alloy inner container carbon fiber.
Background technique
Be accompanied by improving constantly standby power supply continued power time and the requirement of environmental friendliness degree, Another application field-the standby power system of fuel cell cogeneration technology, obtain too increasing practical application, and become the important development direction of present spare international power supply new technology.In the North America, Europe and Japanese, fuel cell has begun to replace conventional batteries as the standby power supply of electronic component, wireless transmission tower and other important communication facilities.Along with the development of national economy, China also increases day by day to the demand of standby power supply, such as the standby power supply of some particular department such as mobile communication base station, military affairs, government, bank, needs to be equipped with technical and good economy performance and eco-friendly standby power supply.Fuel cell exhaust only have water, be zero to pollute to environment, its industrialization and application meeting play a protective role to the ecotope of China, its reliability and stability have great significance for national security.
Yet promote the commercial application of fuel cell cogeneration, the storage hydrogen problem that how can better solve fuel cell just seems particularly important.High-pressure hydrogen storage cylinder has the advantages such as hydrogen storage vessel is simple in structure, the energy consumption of compression hydrogen preparation is less, filling speed is fast, has become the major way of Hydrogen Energy accumulating.Up to now, domestic application about fuel cell cogeneration in the demonstrative project of especially distributed fuel cell cogeneration system, generally is to adopt on-the-spot formula fuel reforming hydrogen producing technology or with general steel cylinder storage of hydrogen.But all there is certain defective in this dual mode, and the former can exert an influence to the Security of fuel cell power generation process owing to relate to High Temperature High Pressure in the fuel reforming process, and the on-the-spot hydrogen that generates can't store; And the latter so that hydrogen storage content only is 1wt.%, can causes and need change frequently gas cylinder in the power generation process, thereby make distributed fuel cell system management process complicated because common steel cylinder quality is heavier.Therefore, develop the high-pressure hydrogen storage cylinder that is applicable to fuel cell cogeneration with characteristics such as lightweight, little volume, high endurances and have urgency.
Summary of the invention
The present invention is directed to the technical problem that exists in the above-mentioned prior art, provide a kind of fuel cell cogeneration entirely to twine hydrogen storage cylinder with aluminum alloy inner container carbon fiber, this hydrogen storage cylinder has large, corrosion-resistant, the not quick-fried first leakage of volume to weight ratio, working pressure fatigue life cycle advantage how.
For achieving the above object, below the technical solution adopted in the present invention:
A kind of fuel cell cogeneration twines hydrogen storage cylinder entirely with the aluminum liner carbon fiber; mainly consisted of by aluminum liner, carbon fiber winding layer and glass fibre protective layer; aluminum liner bottle neck place is the internal thread sealing configuration; on the drum surface of described aluminum liner, alternately twine circumferential winding layer and spiral winding layer; consistent with the spiral winding direction of inner bag oval calotte afterbody, shoulder and the cylinder section of the smooth seamless link of bottleneck and continuously; described winding layer is by the carbon fiber winding layer of tension force control and insulating varnish, twines on the outer surface more described glass fibre protective layer.
Described aluminum liner internal diameter 190mm totally is length 560mm, and wherein cylinder section length is 410mm; End socket place, two ends oval calotte rise is 63mm, and it is that M18, length are the smooth and smooth seamless link of ellipsoid of bottleneck of 24mm that an end contains internal thread, and the selection of this size can be avoided producing the flexing phenomenon at the interior regional area that is connected with cylindrical shell of depressing.Internal container cylinder figure thickness is 3mm, and end socket place thickness is 5mm, stack shell and end socket rounding off.
The design of hydrogen storage cylinder Filament Wound Composite laying scheme and check realize by CADWIND software and ANSYS finite element analysis software respectively among the present invention.Following hypothesis is arranged in modeling process: namely the fiber distributed throughout of gas cylinder is even, and is simultaneously stressed continuous; Inner bag is thin-walled pressure vessel, only seals when gas cylinder uses, and prevents gas permeation, and load is born by continuous fiber; Gas cylinder intensity is all born by fiber, and matrix resin only plays the transmitted load effect, and the resin fracture elongation is enough high, and resin destroys after the fiber breakage.The equal strength that gas cylinder is realized principal direction of stress by reasonable laying quantity and the order of rational hoop and screw fiber.Its concrete canoe is: on the drum surface of aluminum liner, alternately twine circumferential winding layer and spiral winding layer, and consistent with the spiral winding direction of inner bag oval calotte afterbody, shoulder and the cylinder section of the smooth seamless link of bottleneck and continuously, stacking sequence is
This formula represents: 4 layers of hoop twine+2 layers of hoops winding of+4 layers of hoops winding of+4 helical layers winding+4 helical layers winding+2 helical layers and twine+2 layers of hoops winding.
Hydrogen storage cylinder is after carbon fiber winding is complete among the present invention, and twining the glass fiber compound material layer at outer surface is protective layer, and its stacking sequence is that 1 helical layer twines+1 layer of hoop winding.
After the hydrogen storage cylinder manufacturing processing, utilize the determined autofrettage pressure of modeling and simulating among the present invention, namely 58MPa carries out " self-tightening " to the hydrogen storage cylinder after the moulding and processes." self-tightening " is a kind of processing technology of utilizing the material elastoplasticity, giving full play to the strength of materials.After selecting suitable tension force to carry out the superpressure processing, plastic deformation appears in liner material, and outer layer fiber is in the resiliently deformable stage, and the plastic deformation of inner bag can not be eliminated after unloading, produces compressive stress, tensile stress occurs at layer of fibers accordingly.When gas cylinder loaded again, compressive residual stress will be pressed in the tensile stress that produces in the inner bag in the partial offset, thereby improved incipient yield pressure and the anti-fatigue performance of gas cylinder.
Hydrogen storage cylinder disclosed in this invention, mainly be that development for existing hydrogen storage cylinder focuses mostly in the present situation of the automobile-used hydrogen storage cylinder of large volume, develop a kind ofly leak first greatly, corrosion-resistant, not quick-fried for fuel cell cogeneration provides small-sized, lightweight, the volume to weight ratio of hydrogen fuel, store hydrogen gas cylinder that the working pressure fatigue life cycle is many.
