Industry Overview
Floues from non-ferrous metal furnaces refer to the exhaust gases generated during high-temperature smelting processes—such as drying, roasting, smelting, blowing, and refining—of non-ferrous metals (e.g., copper, lead, zinc, nickel, and aluminum). These flues are characterized by their complex composition, high temperature, high dust content, and corrosiveness; if not properly treated, they can pose serious hazards to the environment and human health.

Challenges in Flue Gas Treatment for Non-Ferrous Metal Furnaces
The flue gas temperature is 1000-1200 ℃, containing high concentrations of conductive smoke and acidic corrosive substances.
Temperature changes and load fluctuations can easily cause catalyst poisoning and filter bag sticking.
The collaborative removal of multiple pollutants requires high requirements, and the cost of renovating small and medium-sized kilns is high.
Start stop and material replacement are prone to dust spillage and have poor adaptability to general processes.
Process Route and Technical Description
This route is suitable for the extreme high temperature flue gas of 550 ℃ in non-ferrous smelting, and can achieve deep purification of multiple pollutants in synergy. The core process is:
02
Rapid cooling and temperature reduction
Spray water on the 550 ℃ flue gas for rapid cooling to 200 ℃ to avoid dioxin synthesis and remove large particles of dust.
02
SDS dry desulfurization
Spray ultra-fine sodium bicarbonate into the flue, achieve desulfurization of ≥ 90%, and have no wastewater in a completely dry state.
02
Bag dust removal
High temperature resistant filter bag interception, dust removal ≥ 99.9%, protecting subsequent devices.
02
Activated carbon adsorption
Deeply adsorb organic pollutants such as heavy metals and dioxins.
02
Low temperature SCR denitrification
Anti poisoning catalyst reduces NOx at 180-280 ℃, with a denitrification rate of ≥ 85% and stable compliance with standards.
