高炉煤气系统腐蚀分析及喷淋洗涤系统应用

Analysis of Corrosion of Blast Furnace Gas System and Application of Spray Scrubber System

干法除尘逐渐取代湿法除尘在高炉煤气除尘中被大力推广,但是高炉煤气中的酸性成分对煤气系统的腐蚀成为高炉煤气干法除尘推广过程中无法回避的问题。概述了高炉煤气系统腐蚀的危害及原因,提出了应对煤气系统腐蚀的措施,最后重点介绍了高炉煤气喷淋洗涤系统的工作原理,并根据运行过程中发现的问题提出了有效的改进措施,为今后解决高炉煤气系统腐蚀提供参考。

Dry de-dusting is gradually replacing wet de-dusting in blast furnace gas de-dusting,but the corrosion of the gas system by acidic components in blast furnace gas has become a problem that cannot be avoided in the process of promoting dry de-dusting of blast furnace gas.This article outlines the hazards and causes of blast furnace gas system corrosion,puts forward measures to cope with gas system corrosion,and finally focuses on the working principle of blast furnace gas spray scrubber system,proposes effective improve⁃ment measures based on the problems found in the operation process,which provides refer⁃ence for solving blast furnace gas system corrosion in the future.
