[0002] In the production of steel and other materials, smelting furnaces are often needed. Smelting furnaces are mainly used to melt carbon steel, alloy steel, special steel, and can also be used to melt and heat non-ferrous metals such as copper and aluminum. However, during the operation of the smelting furnace, a lot of smoke will be generated. If the smoke is directly discharged, it will pollute the air and is not conducive to energy conservation and emission reduction. Therefore, dust removal is required.

[0003] In the prior art, the tipping smelting furnace needs to adsorb the generated flue gas and smoke dust during the tipping rotation and dumping smelting water processes. However, the existing dust removal system is generally fixed and will not be adjusted immediately with the tipping adjustment of the smelting furnace, resulting in the dust hood opening being tilted, affecting the dust removal efficiency of the flue gas and smoke dust. Therefore, a medium frequency smelting furnace dust removal system is proposed. Utility Model Content
