Exhaust gases from crushing-drying, electrolyte, and pyrolysis enter TO furnace through separate pipelines. After combustion, they undergo rapid cooling, bag dust removal, multi-stage neutralization spraying (2-4 stages), and wet electrostatic precipitation before being discharged with high-altitude make-up air.
1. Large-air-volume TO furnace design ensures waste gas residence time exceeds 2 seconds, enabling stable and thorough treatment. The chamber uses corundum material for corrosion resistance;
2. TO furnace exhaust immediately contacts atomized liquid water in the quenching tower, rapidly reducing flue gas temperature to prevent re-formation of dioxins;
3. Electrolyte (liquid/gas) from the crushing-drying process serves as fuel, saving natural gas consumption (nearly no need for supplementary natural gas during continuous stable operation);
4. Wet electrostatic precipitator captures mist droplets and other pollutants in flue gas, preventing white fog in exhaust and fluoride entrainment that could cause emission exceedances.
