Description
Technical Field
The utility model relates to a dull and stereotyped deformation piece prosthetic devices of metal especially relates to a hydrogen storage container dull and stereotyped deformation piece electromagnetic pulse prosthetic devices of metal.
Background
The fuel cell using hydrogen as fuel is the best means to relieve energy pressure and realize the harmony of economic development and environment, and thus drives the vigorous development of the hydrogen energy industry. With the continuous temperature rise of the global fuel cell industry, the hydrogen fuel cell automobile as the most representative field of hydrogen energy application will inevitably put higher requirements on the vehicle-mounted hydrogen storage technology. The vehicle-mounted hydrogen storage technology is directly related to the endurance, cost and safety of the fuel cell automobile. At present, domestic hydrogen storage devices mainly comprise the following devices:
1. liquefying to store hydrogen, and cooling the hydrogen to-253 ℃ to liquefy the hydrogen. The liquid hydrogen storage mode has the largest mass energy density and is a light and compact mode. However, the hydrogen liquefaction cost is high, the energy loss is large (the energy required by the hydrogen liquefaction is 30 percent of the heat generated by the combustion of the liquefied hydrogen), and the cover-type vent pipe has evaporation loss. The liquid hydrogen storage process was first used in aerospace, but requires excellent thermal insulation to prevent the liquid hydrogen from boiling off and vaporizing, resulting in a very large liquid storage tank.
2. Hydrogen storage by adsorption, c.cartetis and w.peschka, were the first two students who proposed that hydrogen could be stored by adsorption in activated carbon under cryogenic conditions. They proposed that cryogenic adsorption processes could be considered for large hydrogen storage applications and investigated to obtain a hydrogen storage system at temperatures of-195 c and-208 c,adjustable shrinkage cavityAdsorption isotherms of hydrogen on various activated carbons at pressures of 0-4.15 MPa: when the pressure is 4.2MPa, the adsorption capacity of hydrogen on the activated carbon can reach 6.8 wt% and 8.2 wt% respectively, and when the pressure is equal to 0.2MPa, the adsorption capacity is 4.2 wt% and 5.2 wt%. The wear-resistant pipeline has a unique lattice arrangement structure in the carbon nano material, so that the hydrogen storage quantity of the wear-resistant pipeline is greatly higher than that of the traditional adsorption hydrogen storage material. The carbon nanotubes produce plates with a beveled shape with a layer spacing of 0.337um and a kinetic diameter of molecular hydrogen of 0.289um, so the carbon nanotubes can be used to adsorb hydrogen. In addition, since the hydrogen bonding between the laminates is weak, the hydrogen gas can be released by expansion when the pressure is reduced. In the year of 1998,t-shaped filterThe university of Qinghua began research in the field of hydrogen storage materials, and tests found that: at normal temperature,end socketThe carbon nano tube has high hydrogen absorption speed which can be finished within 3-4 hours, the hydrogen discharge can be finished within 0.5-1 hour, and the hydrogen storage capacity reaches 9.9 Wt%. However, there is a distance for the use of carbon nanotubes as a commercial hydrogen storage material, and the technology for mass production of carbon nanotubes is not yet mature and expensive, and further research on hydrogen storage mechanism, structure control and chemical modification is required.
3. The compressed hydrogen storage mode is to store hydrogen in a high-pressure container in a compressed gas state and can be used at normal temperature. The pressure adopted by the existing compression hydrogen storage mode is generally not more than 35MPa, but the hydrogen storage pressure of a hydrogen storage tank arranged on a hydrogen fuel cell power car of 'hydrogen power No. 3' is up to 70 MPa.
The metal compound hydrogen storage and absorption hydrogen storage of the buffer tube of the pressure gauge have the defects of low gas charging and discharging speed and small hydrogen storage capacity, a huge cooling system and an excellent heat insulating material are required for liquefied hydrogen storage, and a compression hydrogen storage mode is a feasible hydrogen storage method at present.
In the design industry application process, above-mentioned three kinds of hydrogen storage device all need the outside protection casing that sets up, and the protection casing takes place to warp because of external force after, need repair the protection casing and have had traditional plate repair technology mainly to have: the method comprises the following steps of carrying out a manual forming process by using a hand hammer, a top iron and other manual operation tools, wherein the specific implementation mode is that a hammer is used for beating the deformed surface of a metal plate manually, and the deformed area is slightly close to the top iron to achieve the repairing effect, but the defect that the surface of the plate is wrinkled or scratched to influence the repairing effect is overcome; the other method is that the metal surface is locally heated by a metal hot working process and then is processed and repaired; and a shaping process of filling the surface with a filler. However, the traditional mechanical repair process has the problems of low efficiency, long manual repair time, limited repair capability and incapability of repairing metal plates with large deformation or thick thickness, scratches can be generated on the surface of a workpiece and the surface is in mechanical contact when the workpiece is extruded and repaired by mechanical force, the mechanical force cannot be accurately controlled, and even secondary damage can be generated on metal arches. Meanwhile, the traditional repairing process has the defect that the plane smoothness of the plate is reduced after the plate is repaired, so that the appearance is influenced. Therefore, an electromagnetic pulse repairing device capable of rapidly and efficiently repairing the flat deformation piece of the shell of the hydrogen storage container is urgently needed.
