Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a special dust removal device for a fully enclosed electric furnace. Background Art

[0002] With the development of industrial production, when treating the exhaust gas from a fully enclosed electric furnace, special dust removal equipment for the fully enclosed electric furnace is needed;

[0003] Among them, the "online dust removal equipment for waste gas specially used for electric furnaces" disclosed by publication number "CN217391920U" has solved the various drawbacks of existing dust removal equipment that produces a large amount of dust during the production process. After further searching, it was found that the "bag-type dust removal equipment specially used for flue gas treatment of large electric furnaces" disclosed by publication number "CN208340408U" has effectively solved the technical drawbacks such as the filtration effect and gas flow rate greatly reduced when the dust on the surface of the filter bag continues to increase through the technical structure setting of the baffle with an arrow-shaped structure. However, in actual use, the dust removal equipment with similar structure still has many defects, such as: the existing equipment is not convenient for centralized treatment of the treated dust, and it is not convenient for purification of harmful gases in the flue gas, so it is necessary to design a fully enclosed dust removal equipment for electric furnaces.
