FRP Washing Tower

FRP Washing Tower is a typical wet‑type industrial exhaust gas washing and purification unit manufactured from fiberglass‑reinforced plastic.Also known as FRP scrubbing tower,it applies liquid washing to absorb,dissolve and neutralize corrosive industrial exhaust.Thanks to outstanding acid‑alkali resistance of FRP material,the tower works reliably under harsh corrosive conditions where metal equipment would quickly corrode.It is widely used to treat acid mist,alkali fume,soluble toxic gas,malodorous gas and fine dust,helping factories achieve qualified exhaust discharge and meet environmental protection requirements.

Contaminated waste gas is pulled into the bottom section of FRP washing tower by induced draft fan and flows upward.Circulating washing liquid with corresponding chemical agents is pumped to multi‑layer spray pipelines and atomized into fine droplets via special nozzles.Most FRP washing towers adopt counter‑current layout:exhaust gas rises while washing liquid falls down.Internally installed packing creates large specific surface area,so gas and liquid can contact sufficiently.Harmful gas components are dissolved into washing liquid or neutralized through chemical reaction.Fine dust and aerosol are captured by liquid droplets and washed down to the bottom tank.

After repeated washing and absorption,treated gas passes through high‑efficiency mist eliminator at tower top.The mist eliminator traps entrained water droplets and water mist,preventing liquid carry‑over and white smoke at exhaust outlet.Clean gas is discharged up to standard.Washing liquid flows back to the sump tank for sedimentation,pH adjustment and filtration.Treated liquid can circulate for continuous washing,which saves water consumption.Operators only need to replenish water and discharge waste liquid periodically according to working conditions.

The biggest highlight of FRP Washing Tower lies in material performance.Different from carbon steel and stainless steel towers vulnerable to acid‑base corrosion,FRP composite material resists acid,alkali,salt and many chemical media.Tower body is formed by integral winding process,seamless and leak‑free,with high mechanical strength,wind‑resistance and anti‑aging capability.Under normal operating environment,service life can reach more than 15 years,cutting long‑term maintenance and replacement costs significantly.Light‑weight FRP structure reduces foundation load,transportation cost and installation difficulty.

This washing tower possesses many practical advantages.Simple and reasonable internal structure supports 24‑hour continuous operation.Pollutant removal efficiency for soluble corrosive gas can reach 90%‑90%.Internal components including packing,nozzles and mist eliminator can be adjusted according to exhaust composition.It can also serve as pre‑treatment equipment for follow‑up VOC treatment systems to cool hot flue gas and remove dust and acid impurities.Daily operation mainly includes monitoring liquid level and pH value,so maintenance workload is low.

It should be noted that FRP washing tower is suitable for water‑soluble pollutants,and has limited effect on insoluble organic components.Waste liquid produced during operation must be handled properly to avoid secondary pollution.

FRP Washing Tower is widely deployed in electroplating workshops,chemical plants,pharmaceutical factories,printing and dyeing facilities,smelting sites,waste disposal and metal surface‑treatment industries.For corrosive waste‑gas washing scenarios,it is a mature,cost‑effective and reliable environmental‑protection device for modern green manufacturing.
