燃气输配中的噪声及其控制方法

Noise in gas transmission and distribution and its control methods

随着城市化进程的发展和工业用气规模的扩大,高压差、大流量的燃气输配设备的应用越来越普及,随之而来的噪声问题也逐渐成为人们关注的焦点,如不加以合理控制,将会对环境和设备造成巨大的危害。针对这一问题,基于国家标准对环境噪声的要求,研究了相关技术资料和行业经验,详细阐述了燃气输配中阀门噪声和管道传输噪声产生的原因和机理。在分析研究的基础上,系统归纳了降低阀门噪声的典型内置消音器和外置消音器,详细总结了降低管道噪声、汇管噪声以及管道附件噪声的多种解决方案。研究结果对类似燃气输配中的噪声的控制提供了借鉴。

With the development pace of urbanization and the expansion of industrial gas usage, the application of gas transmission and distribution equipment with high-pressure differential and large volume flow has become more and more common. The accompanying noise problem has gradually become the focus of people’s attention, and if not properly controlled, will cause huge harm to the environment and equipment. In response to this problem, based on the requirements of relevant national standards for environmental noise, relevant technical materials and industrial experience were studied, and the causes and mechanisms of valve noise and pipeline noise in gas transmission and distribution were expounded in detail. Based on this analysis and research, the typical built-in silencers and external silencers for reducing valve noise are systematically summarized, and various schemes for reducing pipeline noise, pipe manifold noise and pipeline accessory noise are summarized in detail. The research results provide a variety of alternative solutions for noise control in gas transmission and distribution and have strong reference significance for such situation.
