FRP Absorption Tower
FRP absorption tower (FRP absorption tower) is an environmental protection treatment equipment made of glass fiber reinforced plastic (FRP), which is widely used in industrial waste gas purification, acid and alkali gas absorption and other scenarios. With its corrosion resistance, high strength and lightweight characteristics, it has become an ideal substitute for traditional metal towers, especially for waste gas treatment in chemical, electroplating, pharmaceutical, metallurgical and other industries.
Performance Parameters
- Treatment efficiency: ≥95% (depending on the composition and concentration of the exhaust gas)
- Temperature range: -40℃~120℃ (can be lined with high temperature resistant resin)
- Compressive strength: ≥300MPa
- Flame retardant grade: V0 (flame retardant resin optional)
- PH applicable range: 1~14
Specifications and models
- Model Processing air volume (m³/h) Diameter (mm) Height (m) Applicable medium
- FRP-1000 1000~5000 800~1200 4~6 Acidic gas (HCl, NOₓ)
- FRP-5000 5000~20000 1500~2500 6~10 Alkaline gas (NH₃)
- FRP-30000 30000~100000 3000~5000 12~18 Composite exhaust gas (SO₂+dust)
Corrosion Resistance
FRP material can withstand strong corrosive media such as acid, alkali, salt and organic solvents, and its service life is more than 15 years, which is much higher than metal materials such as carbon steel and stainless steel.
Lightweight, high strength, stable structure
Adopting glass fiber winding process, the tower body has high strength and strong impact resistance, and its weight is only 1/3 of that of steel tower. It is easy to transport and install, and reduces infrastructure costs.
High-efficiency absorption performance
Multi-stage packing layer design, with high-efficiency spray system, large gas-liquid contact area, absorption efficiency of more than 95%, can treat HCl, SO₂, NH₃ and other waste gases.
Low energy consumption and easy maintenance
Optimized structural design, low resistance, low power of supporting fans, and 20%~30% energy saving in operation.
Modular customization
Customized size, air volume (1000~100000m³/h), medium type (acid/alkali/organic exhaust gas) and installation form (vertical/horizontal) according to customer needs.
Service Life
FRP tower life usually 10-20 years, up to 25 years or more under good conditions. PP tower life: usually 5-10 years, may be shortened to 3-5 years under bad conditions. Poor temperature resistance (0℃~80℃), easy to deform at high temperature. Weak UV resistance, low mechanical strength, easy to brittle
Production Process
- Wrapping: Computer-controlled fiber winding technology is used to ensure uniform wall thickness and no welds on the tower body.
- Lining anti-corrosion layer: Lining vinyl resin + surface felt to form a double anti-corrosion barrier.
- Structural reinforcement: Annular reinforcement ribs are added to the outside of the tower body, and the wind pressure resistance reaches level 12.
- Accessory integration: PP filler, spiral nozzle, demister and other components are integrated in the tower, and air tightness test is carried out before leaving the factory.
Main Uses
- Chemical industry: acid waste gas treatment in chlor-alkali and pesticide production
- Electroplating industry: chromic acid mist, hydrogen cyanide gas absorption
- Metallurgical industry: sintering flue gas desulfurization (SO₂)
- Wastewater treatment plant: odor (H₂S, mercaptan) purification
Application areas
- FRP absorption towers have been successfully applied to:
- Power plant desulfurization system
- Electronics factory pickling line waste gas treatment
- Waste incineration plant tail gas purification
- Laboratory ventilation system
