Simulation of Consequences of Hydrogen Leakage Explosion Accident in High-pressure Hydrogen Storage Tank Under the Influence of Atmospheric Environment
In order to study the danger of hydrogen leakage and explosion of high-pressure hydrogen storage tanks under the influence of atmospheric environmental factors,taking the assumption that a high-pressure hydrogen storage tank of a certain enterprise has a hydrogen leakage and explosion accident as the research background,the ALOHA software is used to simulate the dynamic change law of the hydrogen cloud explosion threat area with changes in atmospheric stability,wind speed,temperature and humidity.The simulation results show that firstly,the more stable the weather,the greater the risk of hydrogen cloud explosion.Secondly,the smaller the wind speed,the greater the risk of hydrogen cloud explosion.Thirdly,temperature has few impact on hydrogen cloud explosion risk,and lastly humidity as a factor does not affect the risk of hydrogen cloud explosion.The research results have important guiding significance for the prevention,emergency evacuation and rescue of hydrogen leakage and explosion accidents in high-pressure hydrogen storage tanks.
