Industry Overview
Stamping coke oven flue gas is generated during the coking production process, with complex components containing pollutants such as tar, dust, SO ₂, NOx, and VOCs.
Governance difficulties
Difficulties in the treatment of coke oven flue gas
Viscous impurities are prone to adhere, causing catalyst poisoning, pipeline blockage, and high equipment failure rate.
The flue gas temperature is 180-300 ℃, which is lower than the traditional SCR denitrification requirements and requires additional heating, resulting in high energy consumption.
The coal loading and coke pushing process is prone to the release of smoke and dust, and is prone to acid dew point corrosion and "blue smoke" problems, resulting in poor stability when meeting standards.
Process Route and Technical Description
This route is customized for the high viscosity and narrow temperature window of coking flue gas, which can achieve ultra-low emissions of multiple pollutants. The core process is as follows:
02
Initial effect pre-processing stage
Intercept large tar particles, use specialized filtering materials to prevent catalyst blockage and poisoning, and reduce subsequent loads.
02
SDS dry desulfurization stage
Spray ultra-fine sodium bicarbonate, with a desulfurization efficiency of ≥ 95%, completely dry without wastewater, to avoid acid dew point corrosion.
02
Medium-low Temperature SCR DeNOₓ Stage
The wide temperature anti poisoning catalyst is suitable for 180-300 ℃, with a denitrification efficiency of ≥ 90%, without the need for additional heating, reducing energy consumption.
02
Efficient dust removal and deep purification stage
Bag type dust removal efficiency ≥ 99.9%, can be equipped with wet electrostatic precipitator to remove VOCs and fine particles, eliminating "blue smoke".
