Analysis of the causes and diffusion influencing factors of gas pipeline leakage
摘要
Abstract
Through the analysis of the causes and diffusion influencing factors of gas pipeline leakage, preventive measures aimed at gas leakage accidents are proposed, which is of great significance to reduce the risk of fire and explosion hazards. This paper summarizes the reasons for the leakage of the gas pipeline system in terms of human management, equipment and facilities. By establishing the mathematical model of gas leakage, by means of numerical simulation analysis of the leakage process, variation of the concentration field after gas leak is derived from the three aspects of gas leak conditions, gas species and external wind field. In order to prevent the leakage of gas pipeline, some effective measures are proposed according to the leakage diffusion law, including eliminating necessary conditions of explosion, specifying reasonably gas facilities and strengthening gas safety propaganda.关键词
