Analysis of the Application of Acid Removal System of Blast Furnace Gas Under Dry Dedusting Method
Aiming at the gas corrosion problem appeared in the pipeline after blast fur-nace gas dry dedusting,the paper explores the application state of the blast furnace gas acid removal system on the basis of the existing spray tower with gas cleaning process.By installing additional spray tower with concentrated alkali spray system and applying acid re-moval system such as adding alkali spray in the gas pipeline of hot blast furnace,the pH value of blast furnace gas was raised from 2.3 to 7.0,which solved the problem of corro-sion of the gas pipeline and improved the safety performance of the gas pipeline network.
