Abstract
BF gas bag filter cleaning technology is an important technical innovation for energy saving, emission reducing and clean production for modern blast furnace. It can reduce significantly the fresh water consumption during iron making process and reduce environmental pollution. It has become the development direction of modern BF iron making technology. This paper explain the process flow and technical principle of BF gas dry bag filter cleaning, Introduce the research and application on dry bag filter cleaning technology of BF gas for 5500m3 blast furnace at Shougang Jingtang. The totally dry type low pressure pulse bag filter cleaning technology of gas self-developed has been applied successfully in 5500m3 blast furnace, and standby wet type gas cleaning system has been cancelled. Several key technologies have been developed including gas temperature control, anti-corrosion of pipe, measuring of dust content in gas, dense phase pneumatic transportation of collected dust etc. The totally dry gas bag cleaning technology has reached internationally advanced level.
