摘要
天然气具有无色无味、可燃易爆的特性,一般情况下泄漏时难以被及时察觉,严重威胁了燃气管道系统的安全运行,加臭剂加注技术通过赋予天然气警示性气味成为保障输配安全的核心环节。为此,系统梳理了城市天然气加臭剂加注技术发展现状,聚焦分析了新兴天然气加臭剂加注技术的原理、特征和应用情况,最后展望了未来天然气加臭技术的发展方向。研究结果表明:①现有天然气加臭剂加注技术由于加注方式落后的缘故,燃气加臭易发生末端浓度不达标的情况;②在现有天然气加臭剂加注方式基础上,新型天然气加臭剂加注技术通过优化加臭剂加注方式确保了加臭剂与燃气容易混合;③伴随着物联网、大数据和人工智能等技术的发展,新型天然气加臭剂加注技术可确保天然气加臭效果达标。结论认为:①未来天然气加臭剂加注技术将朝着精准、自动化以及环保的方向发展,并与自动控制、物联网、大数据、人工智能等新兴技术深度融合,为天然气行业高质量发展提供有力支撑。②相关企业应综合权衡技术特点,选择适宜方案;科研机构应加强研发和前瞻布局,推动天然气加臭剂加注技术的创新突破和产业化应用,确保城市燃气系统的安全高效运行。
Natural gas,with colorless,odorless,flammable and explosive properties,can be hardly detected in time in the case of leakage,which seriously threatens the safe operation of gas pipeline systems.The odorant injection technology serves as the core link to ensure safe transportation and distribution by imparting a warning odor to natural gas.In this paper,the development status of city gas odorant injection technologies is systematically reviewed,the principles,characteristics and applications of emerging natural gas odorant injection technologies are mainly analyzed,and the development direction of natural gas odorization technologies are predicted.The following results are obtained.First,due to outdated injection methods,the existing natural gas odorant injection technology is prone to result in substandard end concentration of gas odorant.Second,the new natural gas odorant injection technology ensures easy mixing of odorant with gas by optimizing the odorant injection method of the existing natural gas odorant injection method.Third,with the development of technologies such as Internet of Things,big data and artificial intelligence,the new natural gas odorant injection technology can ensure that the effect of natural gas odorization meets the standard.In conclusion,the future natural gas odorant injection technology will develop towards precision,automation and environmental protection,and will be deeply integrated with emerging technologies such as automatic control,Internet of Things,big data and artificial intelligence,to provide a strong support for the high-quality development of the natural gas industry.Moreover,relevant enterprises should comprehensively weigh the technical characteristics and select appropriate solutions,and research institutions should strengthen research&development and forward-looking layout,and promote innovative breakthroughs and industrial applications of natural gas odorant injection technologies,so as to ensure the safe and efficient operation of urban gas systems.
