工业源VOCs减排过程与阀门密封的研究

Research on the Process of VOCs Emission Reduction from Industrial Sources and Valve Seal

根据《中华人民共和国大气污染防治法》的指引精神,分析当前大气污染现状和近几年大气环境治理的效果;诠释当前VOCs减排政策规划和十三五期间的减排目标,研究工业排放对大气环境的影响;探讨工业排放源流体设备的无组织排放特点;介绍阀门主要泄漏点的逸散特征,研究填料密封形式和低逸散技术、阀门中腔密封元件的设计选型、以及阀座密封结构特性与材料应用;解读国际成熟的工业VOCs排放标准和实验鉴证程序。

According to the guiding spirit of the Law of the People's Republic of China on Prevention and Control of Air Pollution,this paper analyzes the current situation of air pollution and the effect of air pollution control in recent years,annotates the current VOCs emission reduction task plan and the emission reduction targets during the 13th Five-Year Plan,studies the impact of industrial emissions on the atmospheric environment.This paper discusses the characteristics of fugitive emission of valves used in fluid equipment,which is one of the industrial pollutant emission sources.This paper introduces the emission characteristics of the main leakage points of the valve,studies the packing seal form and fugitive emission technology,the design and selection of the sealing element in the valve cavity and the sealing structure characteristics and material application of the valve seat;This paper interprets the internationally mature industrial VOCs emission standards and experimental verification procedures.
