Background
The gas storage tank is widely used in various industrial fields as a gas storage container, and the hydrogen storage tank is a common hydrogen storage container for hydrogen energy. Hydrogen storage technologies are classified into high pressure gaseous hydrogen storage, liquid hydrogen storage, and solid hydrogen storage. The high-pressure gaseous nitrogen storage is to store the hydrogen to 35MPa or 70MPa under certain conditions in a hydrogen storage bottle, the technology is mature, the cost is low, but the metal liner is easy to generate hydrogen embrittlement with the hydrogen, so that the function of the hydrogen storage bottle is invalid; the liquid hydrogen is stored in the ink storage bottle after the low-temperature liquefying process by utilizing the low-temperature liquid hydrogen storage technology, and the nitrogen storage quantity is high, but the requirements on heat insulation and radiation protection of the hydrogen storage container are high and the liquefying cost is high; the solid hydrogen storage is to store hydrogen gas by utilizing metals such as titanium, zirconium and the like and alloys thereof through physical/chemical action to form hydrogen storage metal.
In order to ensure safe storage of high-pressure hydrogen gas, materials commonly used for hydrogen storage tanks include steel, aluminum, alloy, and plastic. In addition, functional paint is coated on the outer layer of the tank body so as to prolong the service life of the hydrogen storage tank, however, along with the prolonging of the service life and the influence of external environment, the outer part of the tank body is gradually oxidized and forms an oxide skin with a certain thickness, so that the surface of the tank body is in a local convex state, but naturally falls off, and the surface of the tank body is concave.
In order to better ensure the service life of the hydrogen storage tank, staff can also check regularly, but for the oxide skin protruding on the surface of the tank body but not falling off, the staff hardly knows whether the oxidation phenomenon of the oxide skin is formed after the oxidation of the paint on the surface of the tank body or is formed after the oxidation of the tank body, so that whether the hydrogen storage tank can be continuously used or not can not be judged.
