摘要
由于广西某糖厂锅炉烟道气变压吸附塔在设计时没有进行应力和安全性分析,为使糖厂锅炉烟道气浓缩变压吸附系统更好、更安全的运行,采用有限元分析软件ANSYS对变压吸附塔整体进行应力分析、强度校核及疲劳寿命估计。结果发现,吸附与解吸过程中的最大应力分别为125.43和24.13 MPa,结合分析设计(校核)理论,得出糖厂锅炉烟道气浓缩吸附塔在强度、稳定性方面都符合安全要求。设计疲劳寿命大于27年,即在正常操作下,吸附塔还可以再运行20年以上。
Due to the design of pressure swing absorption tower in Guangxi sugar refinery boiler flue gas without stress and safety analysis,in order to make sugar mill boiler flue gas concentration PSA system better and safer operation,adopted ANSYS analysis software on the overall adsorption tower stress analysis,strength check and fatigue life estimation.It is found that the maximum stress in the process of adsorption and desorption is 125.43 and 24.13 MPa respectively.According to the theory of combined analysis and design,the results show that in this paper,the strength and stability of flue gas condensing adsorption tower of the sugar refinery meet security requirement; the design fatigue life is more than 27 years,that is,under the normal operation,the adsorption tower can also run for 20 years.
