[0002] The basic production process of iron and steel smelting is to smelt iron ore raw materials into pig iron in the iron smelting furnace, then use pig iron as raw material to smelt steel by different methods, and then cast into steel ingots or continuous casting slabs. However, in the process of iron and steel smelting, Produces more polluting gases, but these polluting gases carry a large amount of heat energy. Traditional steel pollution reduction devices can only achieve a single emission reduction function, but cannot convert and utilize waste heat. Therefore, it is urgent to provide A steel pollution reduction device that can save energy and reduce emissions and can convert and utilize waste heat to achieve rational utilization of resources
