Industry Overview
The flue gas from steel kilns is generated in various smelting processes, with large emissions, high temperatures, complex compositions, containing metal dust, harmful gases, and waste heat resources. It is the main source of pollution in the steel industry.
Governance difficulties
Difficulties in the treatment of steel metallurgical flue gas
Large emissions
The annual exhaust emissions of large enterprises can reach billions of cubic meters.
Large temperature fluctuations
The exhaust gas temperature can reach 800-1600 ℃, with significant differences between different processes.
High concentration of pollutants
Containing fine metal oxide smoke and dust, SO ₂ NOx、 Heavy metals, dioxins, and other harmful substances.
Unorganized emissions are high
The flue gas from processes such as iron tapping and slag tapping in blast furnaces is intermittent, and it is difficult to control the escape.
High value of resource utilization
High temperature waste gas, converter gas, and iron powder dust can all be recycled and reused.
Process Route and Technical Description
Adapt to the high dust, high sulfur, and temperature fluctuation characteristics of sintering flue gas to achieve ultra-low emissions of multiple pollutants. Core process:
02
Preprocessing stage
Gravity settling+rapid cooling heat exchange, intercepting large particle dust, cooling to 180-280 ℃ to adapt to SCR reaction, reducing subsequent load.
02
High temperature dust removal stage
High temperature electrostatic precipitator removes over 90% of metal oxide dust, avoiding catalyst wear and blockage, and extending lifespan by 30%.
02
SCR denitration stage
Anti poisoning wide temperature catalyst reduces NOx at 180-280 ℃, with a denitrification rate of ≥ 90%, and is suitable for fluctuations in sintering conditions.
02
Semi dry desulfurization stage
Spray hydrated lime and SO ₂ reaction, desulfurization ≥ 95%, completely dry without wastewater, avoiding acid dew point corrosion.
02
Deep purification stage
Bag filter intercepts particulate matter and by-products, with a dust removal efficiency of ≥ 99.9%. It can be equipped with wet electrostatic precipitator to further remove dioxins and fine particulate matter, ensuring stable compliance.
