Industry Overview
The composition of the flue gas from the incineration of agricultural and forestry waste is complex, containing particulate matter, greenhouse gases, volatile carcinogens, etc. It is greatly affected by fuel characteristics, combustion conditions, and meteorological factors, resulting in unstable emissions.
Governance difficulties
Challenges in Flue Gas Treatment for Agricultural and Forestry Waste Incinerators
Unstable flue gas
The fuel composition fluctuates greatly, and the adaptability of conventional equipment is poor.
Difficulty in collection
Wide distribution, strong seasonality, and high difficulty in large-scale processing.
Equipment is prone to malfunction
Tar and alkali metals are prone to corrosion and catalyst poisoning.
Difficulty in resource utilization
Adding chemicals can easily contaminate plant ash, limiting its utilization.
Process Route and Technical Description
Route One
SNCR+SCR Combined DeNOx + Cyclone Dust Collector + SYMFS Semi-Dry Desulfurization + Ultra-High-Efficiency Baghouse Filter with High-Purity Gas Chamber
To address the complex composition of flue gas from agricultural and forestry waste incinerators—which is characterized by high sulfur content and a tendency to produce tar and alkali metals—a combined process comprising “SNCR + SCR synergistic denitrification + cyclone dust collector + SYMFS semi-dry desulfurization + ultra-high-efficiency baghouse filter with a high-purity gas chamber” is employed, balancing high-efficiency purification with stable equipment operation.
02
SNCR (Selective Non Catalytic Reduction) denitrification
Inject urea/ammonia water into the furnace at 850 ℃ -1100 ℃ without the need for catalysts, reducing most nitrogen oxides and reducing subsequent loads.
02
SDS (dry desulfurization)
Spray ultra-fine sodium bicarbonate into the flue, react with acidic gases such as SO ₂ and HCl, efficiently remove acid, and have no wastewater or white smoke problems.
02
Medium high temperature bag filter
High temperature and corrosion-resistant filter bags intercept particulate matter and solid salts, prevent bag sticking during medium to high temperature operation, and achieve a dust removal efficiency of ≥ 99.9%.
02
Selective Catalytic Reduction (SCR) denitration at medium and low temperatures
Using alkali resistant metal catalysts, residual NOx is deeply reduced at 200 ℃ -260 ℃ to ensure ultra-low emissions.
02
Waste heat recovery
After purification, the flue gas enters the waste heat recovery system, where the heat energy is converted into steam or hot water for power generation or heating.
Route Two
SNCR+SCR collaborative denitrification+cyclone dust removal+SYMFS semi dry desulfurization+high clean chamber ultra clean bag dust collector
This process is suitable for the complex smoke characteristics of agricultural and forestry waste, balancing purification efficiency and equipment stability. The core process is as follows:
02
SNCR+SCR synergistic denitrification (efficient removal of NOx)
Spray reducing agent in the furnace at 800 ℃ -1100 ℃, initially reduce NOx with SNCR, and then deeply react with SCR to achieve a denitrification efficiency of over 80%, reducing the amount of catalyst used.
02
Cyclone dust removal (pretreatment and load reduction)
Centrifugal force separates large particle dust, reduces subsequent equipment load, and protects precision equipment at the rear end.
02
SYMFS semi dry desulfurization (efficient acid removal and temperature control)
Spray alkaline absorbent to neutralize acidic gases such as SO ₂ and HCl, accurately control temperature to ensure desulfurization effect, and prevent secondary pollution of wastewater.
02
High purity chamber ultra clean bag dust collector (deeply intercepting particulate matter)
The special filter bag "high clean chamber" structure solves the problems of high smoke viscosity, easy corrosion, and bag sticking, with a dust removal efficiency of over 99.9%, ensuring ultra clean emission of particulate matter.
