Research on Vibration Elimination Technology for Online Furnace of Sulfur Recovery Unit
The sulfur recovery device is an important part of the refinery tail gas treatment process,which needs to run smoothly for a long time to ensure that the refinery tail gas emissions meet the environmental protection requirements.In the process gas reheat process of sulfur recovery unit,when the on-line furnace is used to provide the heat source,the on-line furnace,hydrogenation reduction furnace and their related pipelines often produce large vibrations.After analysis,the main cause of the vibration is the"beating vibration phenomenon",that is,a vibration phenomenon formed by the superposition of simple harmonic vibrations in the same direction with little difference in amplitude.The presence of such vibrations not only produces noise that far exceeds the requirements of occupational hygiene,affects the operational flexibility of the plant,but also causes production safety hazards.Therefore,in order for the sulphur recovery unit to operate smoothly for a long period of time and to ensure that the refinery's exhaust emissions meet the standards,such vibrations must be addressed.Combined with the results of on-site vibration measurement and modal analysis of sulfur recovery unit in a refinery,this paper proposes a modification plan for the vibration of the online furnace body of the sulfur recovery unit caused by"beating".This paper mainly introduces the transformation technology of the supporting structure of the large furnace body,and solves the vibration problem of the large online furnace and its related pipelines.
