Application

  • lectroplating Shops: Cyanide & Chromic acid mist control
  • Chemical Plants: HCl/Cl₂ gas neutralization
  • Pharmaceutical Labs: Solvent VOC abatement
  • Emergency Venting: Rapid response to toxic fumes

Working Princple

  1. Gas Intake & Distribution
    • Corrosive fumes enter through FRP ducting (velocity: 1.2-1.5m/s).
  2. Two-Stage Neutralization
    • Stage 1 (Alkaline): NaOH solution (5%-10%) neutralizes acid gases.
    • Stage 2 (Acidic): H₂SO₄ solution (3%-5%) captures alkaline gases.
  3. Enhanced Mass Transfer
    • PP Pall Ring Packing (surface area: 200m²/m³) extends gas-liquid contact to 3-5s.
  4. Mist Elimination
    • Chevron Demister removes 99% droplets (outlet moisture <50mg/Nm³).

Features

  • ✅ Smart Operation
  • Real-time pH monitoring (±0.1) with PLC-controlled dosing, reducing chemical waste by 20%.
  • ✅ Extreme Durability
  • PTFE-lined FRP structure (thickness: 8mm), resistant to 260°F and pH 0-14.
  • ✅ Scalable Design
  • Stackable modules for high-concentration fumes (up to 50,000ppm).
  • ✅ Energy Efficiency
  • Low-pressure drop design (<800Pa) cuts fan power consumption by 35%.
