Simulation method and system for online detection of hydrogen leakage

Abstract

The invention relates to a simulation method and a stimulation system used for online detection of hydrogen leakage. The method comprises the steps of: detecting hydrogen storage and hydrogen concentration around a transmitting device in real time; when the hydrogen concentration detected is more than the set threshold value, determining the size and the shape of a crack through a panoramic camera and forming an initial boundary condition to perform system simulation so as to simulate composition of air around the current device and provide distribution situation and flow direction of hydrogen; and with the combination of material attributes of the device, estimating development situation of the crack by calculating a simulation program. The system comprises a cluster simulation computer, a sensor connected with the cluster simulation computer and used for detecting the hydrogen concentration, and the panoramic camera for detecting the crack. The method and the system can be used to position the crack rapidly in real time and provide data such as distribution concentration and flow direction of hydrogen in a field through high speed simulation, so that the method and the system are suitable for remote disaster detection to guide field rescue operation. The method and the system have better practical value and wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of gas detection, and more precisely relates to a simulation method and system for on-line detection of hydrogen leakage. Background technique [0002] The impact of the energy crisis has gradually penetrated into all aspects of human life. The exploration of new energy is attracting more and more researchers from all over the world to invest in it. Hydrogen, fuel cell wind energy, solar energy, etc. are regarded as important energy development directions in the new century. All countries have invested a lot of manpower and material resources to develop related new energy equipment. A "fourth scientific and technological revolution" that takes new energy as an opportunity is being hit. [0003] Hydrogen is clean and efficient, and it is an important alternative energy source to traditional fossil fuels. However, the road to hydrogen application is not smooth. Hydrogen is flammable, explosive, highly dange...

AI Technical Summary

Problems solved by technology

Hydrogen is flammable, explosive, highly dangerous, colorless, odorless, and inconvenient to observe. When a leak occurs, the concentration of hydrogen on site is unpredictable, and it is difficult to assess the overall degree of danger with a limited number of probes

In addition, the presence of hydrogen will also affect the physical properties of hydrogen storage materials, which will also increase the difficulty of its application.
