Three-Acid Mist Wet Scrubber System | Corrosion-Resistant PP Waste Gas Purification Tower for Aluminum Anodizing, Complete Gas Collection & Neutralization Equipment

Aluminum anodizing workshops generate corrosive three-acid mist during degreasing, caustic etching, hard anodizing and electrolytic coloring:

1. Corrode overhead cranes, rectifiers, chillers and workshop steel frames, shortening equipment service life;
2. Harm operator respiratory health, fail factory environmental audits;
3. Unprocessed acid exhaust leads to heavy fines and production suspension.

MEIAL three-acid mist scrubber delivers full-cycle closed gas disposal to resolve all above risks.

1. Gas Capture: Air hoods collect acid mist above all process tanks;
2. Pressurized Convey: Fan pushes polluted gas into scrubber tower;
3. Primary Spray Layer: Sodium hydroxide circulation liquid neutralizes most acid fume;
4. Secondary Packed Spray: Enhanced gas-liquid contact for deep purification;
5. Gravity Mist Eliminator Block Separate residual liquid droplets;
6. Clean Exhaust: Qualified gas discharged through high exhaust stack.

Circulation tank separately adds sodium hydroxide & soda ash for sustained neutralization performance.

1. Two-Stage Countercurrent Spray, Ultra-High Purification Rate

   Double-layer packing structure extends gas-liquid contact time, fully neutralize sulfuric, hydrochloric and hydrofluoric mixed mist, stable purification rate above 95%, easily pass local environmental monitoring.

2. Full PP Corrosion-Resistant Construction for Long Service Life

   Tower, duct, valves and pumps all adopt acid-proof PP/UPVC materials, resistant to long-term three-acid fume erosion, no rust or leakage, far longer service than carbon steel scrubbers.

3. Separated Gravity Mist Removal, Prevent Fan Corrosion

   Independent baffle demisting chamber intercept liquid droplets carried by exhaust gas, avoid mist entering blower to extend fan service cycle and cut maintenance cost.

4. Recyclable Circulating Liquid, Low Chemical Consumption

   Closed circulation water loop reduces water waste; segmented alkali dosing design balances neutralization effect and soda consumption, lower daily operation expense.

5. Modular Assembly, Flexible Layout Matching All Lines

   Split tower modules, customizable air volume and pipeline layout, fit compact manual labs and large full-auto oxidation plants without large civil reconstruction.

6. Full Set Supporting with MEIAL Surface Treatment Equipment

   Perfectly matched with anodizing rectifier, overhead crane, chiller, pure water machine and wastewater treatment system; one-stop whole workshop environmental solution delivery.

• Supporting lines: Manual anodizing line, mini lab oxidation line, automatic horizontal / vertical anodizing & electrophoresis production line;
• End users: Architectural aluminum profile factories, new energy auto alloy parts workshops, 3C hardware anodizing plants, magnesium alloy micro-arc oxidation factories.
