Chimney anti-corrosion repair construction method based on steel inner cylinder and fluororubber lining system
The invention relates to the technical field of chimney corrosion prevention, in particular to a chimney corrosion prevention and repair construction method based on a steel inner cylinder and a fluororubber lining system, the mode of combining the steel inner cylinder and the fluororubber lining system is adopted, and the chimney is good in corrosion resistance, good in thermal aging resistance and capable of keeping good elasticity after having a thermal load; the applicable operating temperature range is wide, the temperature shock resistance is high, the construction period is short, the construction is simpler, the construction quality control is scientific and concise, and the later maintenance construction is convenient. The problems that in the existing thermal power generation process, due to the fact that a wet desulphurization technology corrodes a chimney, according to an existing scheme, the welding position is prone to being corroded, the construction period is long, the cost is high, or brick joints need to be completely filled with adhesives, and the airflow impact resistance of the surfaces of foam glass bricks is weak are solved.
本发明涉及烟囱防腐技术领域，具体涉及是基于钢内筒和氟橡胶内衬体系的烟囱防腐修复施工方法，采用钢内筒和氟橡胶内衬体系相结合的方式，耐腐蚀性能好，具有良好的抗热老化性能，带热负荷后能保持良好的弹性；适用运行温度范围广，抗温度骤变性强，施工工期短，施工较简单，施工质量控制科学、简洁，后期维护施工方便。解决了现在热力发电过程中，针对湿法脱硫工艺对烟囱存在腐蚀，现有方案易在焊接处产生腐蚀，且工期长成本高，或者是砖缝间需要完全填满胶粘剂，并且泡沫玻璃砖表面耐气流冲击性偏弱的问题。
