Description
Overview of Our Environmental Friendly Acid & Alkali Gas Disposal System
Our environmental friendly industrial air scrubber is a high-efficiency wet scrubbing system specifically designed for acid and alkali gas disposal in industrial facilities. With a proven 98.5%+ purification rate, this system effectively removes harmful corrosive pollutants such as HCl, HF, H₂SO₄, NaOH, and ammonia, helping industrial plants meet strict EPA, OSHA, and international emission standards. With over 12 years of manufacturing experience, we have delivered over 750 customized air scrubber systems to clients across 35+ countries, solving air pollution challenges for chemical processing, electroplating, and pharmaceutical industries.
The entire system is constructed using our industrial-grade customized PP plastic sheet for superior corrosion resistance. It integrates seamlessly with our centrifugal blower fan, air scrubber filler, and activated carbon adsorption tower to form a complete waste gas treatment solution. Unlike steel or FRP scrubbers that corrode rapidly, our PP air scrubber delivers 10+ years of reliable service in harsh chemical environments.
According to the U.S. Environmental Protection Agency (EPA), packed-bed wet scrubbers are the most effective and widely used technology for controlling industrial acid and alkali gas emissions, with removal efficiencies exceeding 90% for most corrosive pollutants.

6. Pressure gauge
Core Working Principle of Acid & Alkali Gas Disposal
Our industrial air scrubber uses a counter-current packed bed design, the gold standard for acid and alkali gas treatment:
- Gas Intake: The centrifugal blower draws polluted exhaust gas into the bottom of the scrubber tower, with a check valve preventing backflow.
- Uniform Distribution: The gas flows through a distribution plate, spreading evenly across the entire cross-section of the tower to eliminate channeling.
- Neutralization Reaction: As the gas flows upward through the PP scrubber packing, alkaline or acidic scrubbing solution sprays downward from the top. The large surface area of the packing creates extensive gas-liquid contact, where acid gases react with alkaline solution (or alkali gases react with acidic solution) to form neutral, non-toxic salts.
- Demisting & Discharge: The cleaned gas passes through a high-efficiency demister to remove liquid droplets, then is safely discharged into the atmosphere with pollutant concentrations well below regulatory limits.

Key Advantages of Our Environmental Friendly Air Scrubber
Superior Corrosion Resistance
Constructed entirely from 100% virgin PP material, our air scrubber is completely immune to corrosion from strong acids, alkalis, and salt solutions. As confirmed by the American Plastics Council (APC), polypropylene offers unmatched chemical stability for industrial corrosion control applications, outperforming steel and FRP in harsh chemical environments.
High Purification Efficiency
The optimized counter-current design and high-performance packing ensure thorough gas-liquid contact, delivering a consistent 98.5%+ purification rate. This guarantees your facility meets even the strictest emission standards, eliminating the risk of regulatory fines and community complaints.
Low Operational Costs
Our air scrubber features a low pressure drop design that reduces energy consumption by 20% compared to generic systems. The automatic pH control system minimizes chemical usage, and the modular design simplifies maintenance, reducing your total operational costs by up to 50% over the system’s lifespan.
Environmental Friendly Design
The closed-loop scrubbing system recycles the washing liquid, minimizing water consumption and wastewater discharge. The neutralized byproducts are non-toxic and can be easily treated in standard wastewater facilities, making our system truly environmentally friendly.

Real-World Case Study: Johor Electroplating Plant
In 2024, a large electroplating plant in Johor, Malaysia, contacted our factory to solve a persistent acid gas emission problem. Their existing steel scrubber had corroded completely in just 18 months, resulting in HCl emissions exceeding the local standard by 5 times and a $35,000 regulatory fine.
After a detailed site assessment, our engineering team designed a custom 20,000 m³/h PP air scrubber system with automatic pH control. We delivered and installed the system within 15 days, with minimal disruption to the plant’s production. The results were outstanding:
- HCl emissions dropped from 160 mg/m³ to 8 mg/m³, well below the regulatory limit of 30 mg/m³
- The system has been operating continuously for 12 months with zero signs of corrosion
- The plant reduced their annual air pollution control costs by 65% compared to the previous steel system
- The plant successfully passed the environmental audit and received a green manufacturing certification
