Acid Fume Scrubber Tower

Our Acid Fume Scrubber Tower for electroplating is a complete exhaust gas treatment system designed to capture and neutralize hazardous airborne contaminants. This wet scrubber system removes acid mists, chrome mist, and VOCs with up to 98% efficiency — ensuring your facility meets OSHA and local environmental standards.

The exhaust gas treatment equipment is engineered for continuous operation in aggressive chemical environments, constructed from corrosion-resistant PP or PVC materials. It is a mandatory component of any responsible plating exhaust system.

How Wet Scrubbing Works

The plating exhaust scrubber uses a counter-current flow design for maximum gas-liquid contact:

Wet Scrubbing Process:

Fumes are captured by hoods at each process tank

Exhaust fans draw fumes through PP/PVC ductwork

Fumes enter the scrubber tower from the bottom

Scrubbing liquid (alkali solution for acid mists) is sprayed from the top

Fumes rise through packed bed media, contacting scrubbing liquid

Contaminants are absorbed / neutralized by chemical reaction

Cleaned gas passes through mist eliminator and is exhausted

Reaction for Acid Mist (H₂SO₄) with NaOH Scrubber: H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O

Typical Scrubber Components:

Key Specifications

The chrome mist scrubber includes a special mesh pad mist eliminator specifically designed to capture fine chromic acid droplets — a requirement for hexavalent chrome plating lines.

Key Advantages

✔ High Efficiency Air Pollution Control (up to 99%)
✔ Corrosion-Resistant PP / PVC / FRP Structure
✔ Automatic pH Dosing & Monitoring System
✔ Low Maintenance Design (no internal moving parts)
✔ Energy Efficient Packed Tower Design
✔ Compact Vertical Footprint Saves Space
✔ Continuous 24/7 Industrial Operation
✔ Compliance with Environmental Regulations

Applications

Our electroplating fume scrubber is used for:

Acid mists: HCl, H₂SO₄, HNO₃ from pickling, activation, and acid plating baths

Chrome mist: Hexavalent and trivalent chrome plating lines

Cyanide gases: Alkaline cyanide plating (requires specialized oxidation scrubbing)

Nitrous fumes: Chemical polishing and stripping operations

Heated baths: Steam and vapor from hot process tanks

The wet scrubber for plating lines is typically located outside the facility, with ductwork connecting each tank hood to the central scrubber. A booster fan may be required for long duct runs.
