Description

Technical Field

[0001] The utility model relates to the technical field of electric furnace purification, in particular to an electric furnace fume purification device. Background Art

[0002] When processing and refining metal parts or steel, electric furnaces are often used for processing. During the operation of the electric furnace, a certain mixture of smoke, gas and impurities will be produced. This mixture cannot be discharged directly. On the one hand, the mixture has a high heat content and is easy to injure workers accidentally. On the other hand, because the mixture contains substances that pollute the environment, it needs to be processed through dust removal and other processes before it can be discharged to prevent air pollution.

[0003] When processing, most flue gases must pass through a preheating tank and then enter a cooling and settling chamber. After the cooling and settling chamber, a water-cooled wall must be set up to cool down. The cooling measures of the entire system are cumbersome and the operation is extremely dangerous. Finally, the flue gas temperature at the water-cooled wall outlet is 350-450°C. Conventional cyclone dust collectors and other dust collectors cannot meet the dust emission standards in the flue gas, and the filter material of the high-temperature bag dust collector cannot meet the operating temperature. Even if the flue gas temperature is reduced to below 200°C, the working efficiency is low. For this reason, an electric furnace flue gas purification device is proposed. Utility Model Content
