The PVC Wet Scrubber is a high-performance air pollution control system engineered for aggressive industrial exhaust containing acidic gases, chlorine (Cl₂), hydrogen chloride (HCl), and other corrosive contaminants. Constructed entirely from rigid Polyvinyl Chloride (PVC) , this scrubber offers exceptional chemical resistance, making it the ideal choice for chemical processing, electroplating, pharmaceutical, and metal finishing industries where standard materials fail prematurely .
Unlike carbon steel or FRP alternatives, PVC provides inherent resistance to a wide range of acids, alkalis, and oxidizing agents, ensuring decades of reliable service in the harshest environments .
Why Choose PVC Wet Scrubber?
| Feature | Benefit |
|---|---|
| Superior Chemical Resistance | PVC withstands attack from hydrochloric acid, sulfuric acid, chlorine gas, and caustic solutions—materials that rapidly corrode metal equipment |
| Lightweight Construction | Easier to install and support compared to metal towers, reducing structural requirements |
| Cost-Effective | Lower material and fabrication costs than stainless steel or exotic alloys |
| Seamless Welded Joints | Heat-welded construction ensures leak-proof integrity for zero fugitive emissions |
| Low Maintenance | Non-corroding surfaces resist scaling and buildup, minimizing cleaning requirements |
PVC Wet Scrubber Working Principle
The PVC wet scrubber operates on the principle of gas-liquid absorption to remove pollutants from industrial exhaust streams :
Gas Inlet: Contaminated exhaust gas enters the bottom of the scrubber tower through a tangential or bottom inlet.
Packed Bed Contact: The gas rises through a packed bed of PP Pall rings or multi-faceted hollow spheres , which creates maximum surface area for gas-liquid contact –.
Counter-Current Scrubbing: Scrubbing liquid (water, caustic solution, or chemical reagent) is sprayed from the top and flows downward, contacting the rising gas stream. Pollutants are absorbed, neutralized, or chemically reacted with the liquid
Mist Elimination: Clean gas passes through a PVC demister pad or chevron mist eliminator to remove entrained droplets before discharge.
Liquid Recirculation: Scrubbing liquid collects in the integrated tank at the bottom and is recirculated by a corrosion-resistant pump, minimizing water and chemical consumption .
