Description
Technical Field
The invention belongs to the technical field of hydrogen energy storage, and particularly relates to a metal hydride hydrogen storage tank with a spiral structure.
Background
At present, with the aggravation of energy crisis and the enhancement of environmental awareness, the utilization of hydrogen energy is receiving more and more extensive attention, wherein the storage of hydrogen is one of the main technical bottlenecks in the practical process of hydrogen energy.
The prior art has three main practical hydrogen storage methods: high pressure vessel hydrogen storage (e.g., steel cylinder), cryogenic liquid hydrogen storage tank (cryogenic dewar), and metal hydride solid state hydrogen storage. The metal hydride solid-state hydrogen storage technology realizes the storage of hydrogen by utilizing the reaction of hydrogen and hydrogen storage alloy, has the advantages of high hydrogen storage density, low pressure, good safety, high hydrogen purity and the like compared with other hydrogen storage modes, and is an important direction for the development of the hydrogen storage technology.
However, the current metal hydride solid-state hydrogen storage technology has the following technical bottlenecks:
1) the hydrogen storage alloy is pulverized to influence the heat transfer performance of the hydrogen storage tank. The hydrogen storage alloy generates a large amount of heat when absorbing hydrogen, and absorbs a large amount of heat from the outside when releasing hydrogen, while the temperature seriously affects the hydrogen absorbing/releasing rate of the hydrogen storage alloy; in addition, the hydrogen storage alloy can generate violent lattice expansion/contraction in the hydrogen absorption/desorption process, so that the hydrogen storage alloy is pulverized, and the pulverized hydrogen storage alloy causes extremely poor heat transfer performance (the effective heat conductivity of the hydrogen storage alloy is about 1W/m/K) of the hydrogen storage alloy, so that the heat transfer of a hydrogen storage alloy powder bed body in the metal hydride hydrogen storage tank is one of the main factors influencing the performance of the hydrogen storage tank.
2) The local aggregation of the hydrogen storage alloy powder is liable to cause a safety accident of the hydrogen storage tank. Under the action of the expansion/contraction and gravity of the hydrogen storage alloy, the hydrogen storage alloy powder can be gradually settled, so that the hydrogen storage alloy powder is gathered at certain parts in the hydrogen storage tank, the gathered hydrogen storage alloy can exert great stress on the tank body during hydrogen absorption and expansion, the tank body is excessively plastically deformed or even broken, and safety accidents are caused.
In order to prevent the above problems, the first requirement is to improve the heat exchange performance of the hydrogen storage alloy powder bed body to ensure the rapid hydrogen absorption/desorption of the metal hydride hydrogen storage tank; secondly, the local aggregation of the hydrogen storage alloy powder in the hydrogen storage tank is prevented, so that the hydrogen storage alloy powder is uniformly distributed in the tank body, the excessive deformation of the tank body caused by overlarge stress is prevented, and the use safety and the service life are ensured.
