Anti-Corrosion PP PTFE PVDF Plastic Chevron Vane Mist Eliminator for Strong Acid Scrubbing, FGD & High Liquid Load Gas-Liquid Separation
Plastic Chevron Mist Eliminator Product Description
Plastic Chevron Mist Eliminator is a corrosion-proof gas-liquid separation device engineered for the most aggressive chemical environments. Constructed entirely from formed PP, PTFE, PVDF, or FRP vanes arranged in a precise zigzag pattern, it separates entrained liquid droplets from gas streams through inertial impaction. As the gas flows through the tortuous vane path, the heavier liquid droplets cannot follow the rapid directional changes and strike the vane walls, where they coalesce and drain downward via integrated collection pockets. Its all-plastic construction provides absolute immunity to acids (including hydrofluoric acid and aqua regia), strong alkalis, and chlorinated solvents—making it the essential solution for acid pickling lines, wet chlorine drying towers, FGD scrubbers, and semiconductor-grade chemical processes where stainless steel or alloy demisters would be destroyed in days or weeks.
Product Highlights
- Universal Corrosion Resistance: All-plastic construction in PP, PTFE, or PVDF resists every acid, alkali, and solvent, including HF, boiling sulfuric acid, and wet chlorine gas—ensuring maintenance-free service in conditions that rapidly destroy metal demisters.
- Extremely High Liquid Handling Capacity: The open zigzag vane design handles liquid loads exceeding 100 m³/m²·h, making it 5–10 times more tolerant of heavy liquid loads compared to wire mesh mist eliminators.
- Anti-Clogging & Self-Cleaning: Wide vane spacing (20–50mm) and smooth non-stick plastic surfaces prevent blockage from solids, slurries, or scaling fluids, ensuring reliable operation in fouling-prone processes.
- Low Pressure Drop: The streamlined vane geometry with integrated liquid pockets creates minimal flow resistance, typically 40–180 Pa, reducing fan power consumption and operating costs.
- Lightweight & Easy Installation: Weighing only 1/10 to 1/5 of equivalent metal vane packs, plastic chevron assemblies are easy to handle, cut, and install, with reduced structural load on the vessel.
- Double-Pocket Anti-Re-Entrainment Design: Each vane is equipped with collection hooks or pockets that capture separated liquid and channel it away, preventing droplet re-entrainment even at high gas velocities.
