Analysis of Reasons for Blockage in the Tail Gas Pipeline of Activated Carbon Desulfurization and Sulfuric Sulphuric Acid Production
During the operation of the activated carbon desulfurization and denitrification sulphuric acid production system in Hansteel company,it is difficult to detect the gradual blockage of the sulphuric acid production tail gas pipeline,resulting in poor flow of tail gas and system pressure suppression,which seriously restricts the normal production of activated carbon desulfurization and denitrification.By checking the tail gas pipeline section by section,the location of the blockage was determined and the hardened material was analyzed.The cause of the blockage was ultimately determined,and the reasons for the blockage were analyzed from the aspects of sulphuric acid production operation,sulphuric acid concentration meter distortion,sintering production,and online maintenance.In production,it is necessary to strictly monitor the changes in various parameters and the above influencing factors during the operation of the system to ensure the normal and stable operation of the sulphuric acid production system.
