Description
Technical Field
The utility model belongs to the technical field of substance content detection, and particularly relates to a solid metal hydrogen permeability detection device.
Background
The current environmental problems are increasingly highlighted, and hydrogen is therefore widely welcome as a widely available energy source with high heating value, low pollution. To drive the development of hydrogen energy, many countries have taken strategic actions to expedite the construction of hydrogen storage, transportation and hydrogenation infrastructure. However, while hydrogen is considered an ideal energy source, it still faces some challenges and obstacles in practical use. One of the problems is that atomic hydrogen permeates into the steel during the storage and transportation of hydrogen, so that the concentration of hydrogen in the steel is continuously increased, the toughness of the steel is reduced, the brittleness is increased, the hydrogen embrittlement phenomenon is caused, and sudden serious damage accidents can be caused. Accordingly, there is a need in the industry for a hydrogen permeability detection technique for monitoring and calibrating the rate of hydrogen permeation in steel structures and alerting the equipment to the risk that hydrogen accumulation within the equipment may initiate corrosion damage.
The currently more common method of hydrogen permeation in solid metals is the carrier gas thermal extraction method. The inspector can test the permeated hydrogen content in the metal by changing different hydrogen precipitation heating temperatures, and can also measure the total hydrogen content in the metal, including molecular hydrogen and permeated hydrogen. The carrier gas thermal extraction method carries the separated hydrogen into a thermal conductivity cell or an infrared detection module for testing through inert gas. Because of the higher hydrogen extraction temperatures that can be used, a sample test can be completed in tens of minutes, but approximately 1 hour is required for thermal conductivity cell stabilization before testing. However, the overall efficiency of the method is relatively low, and the price of the thermal conductivity detection pool and the infrared detection module is high, so that the hydrogen detection cost is increased, and the structure of the hydrogen detection device is complex.
The palladium material has high dissolution rate and good selectivity to hydrogen, is widely selected as a gas-sensitive material of a hydrogen sensor, but a pure palladium film is easy to generate hydrogen embrittlement, so that the stability of the sensor is greatly influenced; the hydrogen sensor based on palladium and an alloy system thereof can work at room temperature, has good selectivity, high stability and wide range, and is widely researched and applied. Among them, palladium-gold alloy hydrogen sensitive materials are the most popular hydrogen detection materials in recent years because of their superior properties.
The existing metal hydrogen permeation content detection device is less, and most of gas sensitive elements are of pressure type, semiconductor type and the like, so that the gas sensitive elements are easily influenced by environmental factors in practical application, and the gas sensitive elements are difficult to accord with metal hydrogen permeation detection with complex working conditions such as industrial hydrogen production, hydrogen storage, hydrogen transportation and the like;
Most of the existing hydrogen permeation detection devices detect metal samples, and the detection devices can only be used in laboratory environments and cannot be applied to actual occasions;
The existing hydrogen permeation detection device has low detection sensitivity and cannot reflect the metal hydrogen permeation condition in time.
