近日，动力厂协同相关部门，经周密部署与艰苦奋战，安全、高效地完成了1#、2#环集烟气风机及附属设备设施拆除任务。此次拆除工作是动力厂展现技术攻坚、变废为宝，践行“极致降本”理念的一次成功实践。

动力厂1#、2#环集烟气风机及附属设备设施自硫酸新环集系统建成后停用至今，风机系统虽已与硫酸主烟气系统隔离断开，但其烟气管道、钢结构平台、电缆桥架等设备设施常年露天暴晒雨淋，腐蚀严重，存在安全风险，须进行拆除作业。此次拆除工作面临巨大挑战：悬于10米高空、直径分别达3.2米和2.5米、总长约70米的庞大烟气管道，以及作业区域紧邻氧气、生产水等重要管线的复杂环境，使得常规方法难以适用。项目团队迎难而上，以技术创新破局，针对超高超大管道的安全解体，创新采用“模块化切割+定位吊装”工艺，通过精确计算重心、设计分段切割线，并利用大型吊车配合手拉葫芦进行多点微调，实现了巨型管段在狭小空间内的稳定切割与精准吊运，有效规避了对邻近运行管道的任何潜在干扰，成功攻克高空高危区域大型构件拆除的核心难题。本次拆除工作共完成DN2500大型烟管破坏性拆除70余米，回收各类线缆500余米。

与此同时动力厂深植“极致降本”意识，对拆解的每一块钢板、每一段电缆、每一件可用备件进行细致筛选、分类与评估，拆除的大量钢材、电缆桥架组件及部分设备部件经专业修复或巧妙改造后，将重新服务于其他生产环节，实现变“废”为宝。
