[0002] A blast furnace is a device used for ironmaking. It is shaped like a tall tower with a lining and refractory materials inside. The role of the blast furnace in ironmaking is to charge raw materials such as iron ore, coal, and coke into the furnace, and reduce the iron oxides in them into iron through high-temperature heating. This process involves multiple steps and systems, including a charging system, a feeding system, an air supply system, a gas dust removal system, an iron slag treatment system, and a blowing system, which work together to ensure the continuity and efficiency of the ironmaking process. For this purpose, a flow-adjustable pneumatic atomizing water dust removal device for use in front of a blast furnace is proposed.
