[0002] Converter steelmaking uses hot metal, scrap steel, and ferroalloys as the main raw materials. Without relying on external energy, the steelmaking process is completed in the converter by the physical heat of the molten iron itself and the chemical reactions between the components of the molten iron. Converters are divided into acidic and basic according to the refractory materials, and are divided into top blowing, bottom blowing, and side blowing according to the position where the gas is blown into the furnace; they are divided into air converters and oxygen converters according to the type of gas.
[0003] The converter gas recovery system in the steelmaking process generally adopts a dry dust removal process. The process flow is as follows: The high-temperature flue gas during the converter smelting process is first cooled by the vaporization cooling flue and the evaporation cooler and then enters the electrostatic precipitator for fine dust removal; secondly, under the action of the axial flow fan, the flue gas passes through the switching station, the unqualified gas is ignited and discharged through the chimney, and the qualified gas is cooled by the gas cooler and then stored in the converter gas holder. Finally, the converter gas is pressurized by the blower and supplied to users such as sleeve kilns and hot rolling as fuel. However, the above-mentioned converter gas cooler usually directly cools by flowing water, resulting in a small contact area between water and gas, poor cooling effect of the gas, high temperature of the converter gas, and even reaching the 70°C alarm upper limit in summer, reducing the service life of the diaphragm of the converter gas holder; at the same time, the water content of the converter gas is large, exacerbating the corrosion of the gas holder.
