Problems solved by technology
Furnace soot is solid particles formed by condensation or oxidation in the air of sublimates or steam produced by physical and chemical processes during metal smelting or heating, such as oxygen converter soot, oxygen blowing open hearth furnace soot, electric furnace soot, etc., mainly It is a metal oxide with very fine particles, and most of them are discharged through the chimney with high-temperature flue gas. Since the particles in the dust removal waste from converter steelmaking are relatively large, direct discharge will cause air pollution, and the dust removal waste from converter steelmaking contains a large amount of Iron powder particles, direct discharge causes waste of resources

The invention relates to the technical field of converter steelmaking, specifically to a recycling device for converter steelmaking dedusting waste and an application method thereof. The recycling device for converter steelmaking dedusting waste comprises a closed recycling box body, wherein the recycling box body is communicated with an external water source through a high-pressure spray head fixedly connected to the recycling box body via bolts; a feeding port and a discharging port are formed in the side face of the recycling box body from top to bottom; and an annular magnet is arranged inand fixedly connected with the recycling box body. By using the device, converter steelmaking dedusting waste particles in the converter steelmaking dedusting waste can be removed and are prevented from being directly discharged into the atmosphere to cause atmospheric pollution; meanwhile, iron powder particles in the converter steelmaking dedusting waste can be recycled, so resource waste is reduced; and dedusting water can be recycled, so water resources are saved.
Description
technical field [0001] The invention belongs to the technical field of converter steelmaking, and specifically relates to a converter steelmaking dust removal waste recycling device and a use method. Background technique [0002] Converter steelmaking uses molten iron, scrap steel, and ferroalloy as the main raw materials. The steelmaking process is completed in the converter by the physical heat of the molten iron itself and the heat generated by the chemical reaction between the components of the molten iron without the aid of external energy. According to the refractory material, the converter is divided into acidic and alkaline; according to the position where the gas is blown into the furnace, there are top blowing, bottom blowing and side blowing; according to the type of gas, it is divided into air converter and oxygen converter. Basic oxygen top-blown and top-bottom compound-blown converters are currently the most commonly used steelmaking equipment due to their fast...
