Technical Background
The emission of flue gas in the steel production process is mainly concentrated in the sintering process, with sintering plants accounting for more than half of the total emissions from steel enterprises. Sintering flue gas contains a large amount of pollutants such as particulate matter, SO2, NOx, heavy metals, and dioxins, posing severe environmental pollution. Therefore, to reduce sintering machine exhaust emissions and control pollution, sintering flue gas recirculation technology has gradually emerged and gained widespread application.
Technical Principle
Sintering flue gas recirculation technology is an energy-saving and emission-reduction method that involves recycling a portion of the heat-carrying gas emitted during the sintering process back to the sintering strand after the igniter for reuse. Its working principle utilizes a recirculation system to reintroduce some of the hot flue gas generated during production back into the sintering process, thereby reducing the emission of polluting gases. This technology recycles and utilizes the waste heat from sintering flue gas, enhancing the thermal efficiency of sintering, reducing fuel consumption, and simultaneously decreasing the volume of flue gas emitted from sintering production, which lowers the treatment load on flue gas purification facilities.
Technical Characteristics
Energy Saving and Emission Reduction: By recycling and utilizing the waste heat from sintering flue gas, fuel consumption is reduced, and pollutant emissions are decreased, achieving the effects of energy saving and emission reduction.
Increased Production: The heat and combustible components in the recirculated flue gas are effectively utilized, improving the thermal efficiency of the sintering process, thereby increasing sinter production.
Reduced Energy Consumption: Due to the utilization of recirculated flue gas, the introduction of fresh air is reduced, lowering the exhaust load and energy consumption of the sintering machine.
Flexible Regulation and Control: Sintering flue gas recirculation technology allows for flexible regulation and control of the quantity and temperature of the recirculated flue gas according to production needs, meeting different production requirements.
