안 FRP Denitrification Tower is a specialized gas treatment system designed to remove nitrogen oxides (NOₓ) from industrial exhaust gases using chemical absorption or catalytic reduction. These towers are constructed from 유리섬유 강화 플라스틱(FRP) for their outstanding corrosion resistance, structural integrity, and long-term durability in chemically aggressive environments.
제품 성능 소개
Denitrification towers are essential in steel manufacturing, waste incineration, power plants, fertilizer production, chemical synthesis, and other industries where NO and NO₂ gases are generated. These towers play a vital role in achieving environmental compliance with national and international NOₓ emission regulations, including EPA, EU standards, 그리고 local air quality management laws.
Depending on the process, denitrification towers may operate through wet scrubbing, selective catalytic reduction (SCR), 또는 selective non-catalytic reduction (SNCR) mechanisms. FRP is particularly suited to wet scrubbing applications where acidic or oxidizing solutions such as H₂O₂, NaOH, 또는 KMnO₄ are used to neutralize NOₓ.
주요 특징들
-
부식 저항: Handles oxidizing, acidic, and alkaline environments with superior durability.
-
High Removal Efficiency: Up to 95–98% NOₓ removal with optimized reagent dosing and tower design.
-
Custom Engineered: Designed per emission load, gas flow rate, and temperature for optimal treatment.
-
경량 구조: Easier handling and reduced installation cost vs. metal alternatives.
-
Long Service Life: FRP life expectancy ranges from 15 to 25 years with minimal maintenance.
Working Principle (Wet Scrubbing)
-
Exhaust gas enters the lower inlet of the tower.
-
Liquid oxidizing agent (e.g., NaClO₂, H₂O₂, or KMnO₄) is sprayed downward through spray nozzles.
-
The NO and NO₂ are absorbed and oxidized into HNO₃ 또는 NO₃⁻ compounds in the packing section.
-
Cleaned gas passes through the mist eliminator and exits through the exhaust stack.
-
Absorbent liquid is recirculated via a chemical-resistant pump.
Typical Applications
-
Waste incineration plants
-
Chemical fertilizer production
-
Nitric acid production units
-
Steel mills and foundries
-
Glass manufacturing
-
Thermal power generation
-
Pharmaceutical plants

자주하는 질문
질문 :
What is an FRP Purification Tower?
ㅏ :
An FRP Purification Tower is a vertical or horizontal tower system made of Fiberglass Reinforced Plastic (FRP) used to purify and treat industrial exhaust gases by removing harmful contaminants such as acid fumes, alkaline vapors, ammonia, chlorine, sulfur compounds, and odors. It operates using wet scrubbing, chemical absorption, or other neutralization methods.
질문 :
What gases can an FRP Purification Tower remove?
ㅏ :
Acidic gases: HCl, H₂SO₄ mist, SO₂, Cl₂ Alkaline gases: NH₃ Organic compounds: VOCs (when combined with bio or carbon filters) Corrosive vapors: HF, HBr, NOₓ Odorous gases: H₂S, mercaptans
질문 :
Why use FRP instead of steel or PVC?
ㅏ :
Excellent corrosion resistance Longer service life (15–25 years) Resistant to acids, alkalis, oxidants, and saltwater Lightweight and easy to install Lower maintenance costs Suitable for outdoor and marine environments
질문 :
How does an FRP Purification Tower work?
ㅏ :
Polluted gas enters the tower through the inlet. The gas passes upward (countercurrent) through scrubbing media. A liquid (usually water or a chemical solution) is sprayed downward. Pollutants are absorbed or neutralized in the scrubbing section. Clean air exits through the demister and stack.
