Dangerous Gas Leakage And Diffusion Simulation And Countermeasures

Dangerous gases are widely present in modern production and people’s daily lives.Once improperly used or maintained,they can easily cause leaks,leading to major accidents such as fire,explosion,burns,poisoning,and suffocation,which seriously endanger people’s health and asset safety.In order to understand the law of dangerous gas leakage and diffusion more comprehensively and formulate corresponding preventive and countermeasures,this paper conducted a numerical simulation study on dangerous gas leakage and diffusion.The thesis mainly studies from three aspects.First,this thesis analyzes the research progress of domestic and foreign researchers on gas leakage and diffusion,and at the same time carries out the hazard identification of dangerous gases,and summarizes the characteristics of gas leakage and the influencing factors of the diffusion concentration distribution.Secondly,the numerical simulation software Pyrosim and Fluent are used as computing platforms to simulate the heat radiation distribution of the fire in the natural gas storage tank area under different wind speeds and the concentration distribution of chlorine gas under different wind speeds,leak speeds,and leak heights The results are consistent with the theory of leakage and diffusion,and the theoretical calculations can be used to calculate the safe distance for firefighters to rescue disasters in the event of a natural gas leak.According to the process of chlorine gas invading the human body,the gas cloud concentration and radius table at different distances from the downwind direction are calculated and the dangerous area is calculated.Classification,and finally,put forward the prevention and response measures of dangerous gas leakage accidents.
