摘要:
选取某石化企业的双塔设备作为研究对象,将现场实测与流固耦合计算相结合进行振动分析,其中稳定塔高33 m,分馏塔高24 m,塔内气相介质为天然气,液相为烯烃.采用风速风向仪对塔设备上游的风速风向进行测量,用电阻式应变片测量稳定塔的轴向应变,用磁电式振动传感器测量塔设备振动速度和位移,得到了在内、外流动载荷作用下双塔设备的动态响应和固有频率.结果表明:该文所采用的流固耦合计算方法可有效评估塔设备的振动情况,为多塔设备的安全运行提供参考.
Abstract:
In this study,the on-site measurement and fluid-solid coupling calculation are performed for a chemical twin-tower with heights of 33 m and 24 m in a petrochemical company to analysis its vibration.The gas phase medium is natural gas and the liquid phase medium is olefin.The anemometer is used to measure the wind speed and direction upstream of the equipment,the resistance strain gauges are used to measure the axial strain of the stabilizing tower,the magnetoelectric vibration sensors are used to measure the vibrating speed and displacement of the twin-tower.Dynamic response and natural frequency of twin-tower under internal and external flow loads are obtained.The result shows that the fluid-structure coupling calculation method used in this paper can effectively evaluate the vibration and provide a reference for the safe operation of the multi-tower equipment.
