Industry Overview
The alkali recovery furnace is a core environmentally friendly energy equipment for papermaking, with high temperature and humidity in the flue gas, and characteristic pollutants such as total reduced sulfur.
Governance difficulties
Challenges in Flue Gas Treatment for Alkali Recovery Furnaces
Moisture content exceeding 26%, exhaust temperature ranging from 165 ℃ to 250 ℃.
Containing conventional pollutants and odorous substances such as total reduced sulfur.
High humidity and high temperature flue gas tend to condense when cooled, resulting in the appearance of "big white smoke".
Natural SO ₂ emissions are extremely low and do not require additional desulfurization equipment.
Process Route and Technical Description
Boiler (alkali recovery furnace) → SDS dry desulfurization (baking soda injection) → bag filter (FF) → SCR denitrification reactor → waste heat recovery device → induced draft fan/chimney
02
SDS dry desulfurization (baking soda injection)
Spray ultra-fine sodium bicarbonate and react with SO ₂ for efficient desulfurization, with low temperature drop and no wastewater.
02
Bag filter (FF)
Capture dust and desulfurization by-products, reduce dust content to below 10mg/Nm ³, and protect the catalyst.
02
SCR denitration reactor
Inject reducing agent and convert NOx into harmless substances under the action of medium low temperature catalyst.
02
Waste heat recovery device
Recovering heat energy for heating production, improving energy utilization efficiency, and regulating exhaust temperature.
