某钢吸收塔火灾后的可靠性鉴定

Reliability identification of a steel absorption tower after fire

某电厂脱硫吸收塔塔内发生火灾,灾后钢筒壁发生较大的局部变形,塔内支撑梁等附属结构也受到了火烧影响,严重影响了结构的安全使用.为探明现结构的可靠性,本文基于三维扫描技术,对筒壁变形进行了全面检测,介绍了火灾后钢吸收塔的主要检测方法和鉴定程序,提出了进一步的研究方向,为其他相似工程提供参考.

In the case of fire in a absorption tower,a large local depression deformation occurred after fire disaster;and the supporting beam in the tower were also affected,so as to seriously affect the safety and use of the structure.Based on the 3 D scanning technology,the deformations of steel tower are identified.This paper describes the process and results of safety identification of the absorption tewer.Finally,same further research direction is put forward.
