RTO

Zeolite Concentrator Rotor (RTO System)

Overview

The Zeolite Concentrator Rotor System is an advanced and highly efficient environmental protection equipment designed for treating large-volume, low-concentration Volatile Organic Compound (VOC) exhaust gases.

By combining continuous adsorption and desorption technology with a Regenerative Thermal Oxidizer (RTO), the system concentrates dilute exhaust gas into a high-concentration stream before destruction. This process significantly reduces overall energy consumption and operational costs.

How It Works

The core of the system is a continuously rotating wheel honeycomb-structured with hydrophobic zeolite adsorbents. The process operates in three continuous zones:

1. Adsorption Zone: Large volumes of low-concentration VOC gas pass through the rotor. The zeolite honeycomb adsorbs the VOCs, allowing clean, purified air to be safely discharged into the atmosphere.
2. Desorption Zone: A small volume of hot air (approx. 180°C–220°C) strips the adsorbed VOCs from the rotor, concentrating the exhaust gas by a ratio of 10:1 to 30:1.
3. Cooling Zone: The desorbed sector is cooled down by ambient air to restore its adsorption capacity for the next cycle.

Key Features & Advantages

• High Purification Efficiency: Achieves VOC removal rates of up to 95%+ with stable continuous operation.
• Significant Energy Savings: High concentration ratios drastically reduce the airflow entering the RTO, cutting auxiliary fuel consumption by up to 80%–90%.
• Incombustible & Safe: Uses inorganic hydrophobic zeolite, which is non-flammable, safe, and highly durable.
• Compact Footprint: High space utilization compared to traditional carbon bed adsorbers.
• Long Service Life: Resistant to high desorption temperatures and minimal performance degradation over time.

Typical Applications

• Surface Coating & Painting: Automotive, aerospace, shipyards, and heavy machinery industries.
• Printing & Packaging: Gravure printing, flexible packaging, and film coating.
• Electronics & Semiconductors: Display panels, PCB manufacturing, and semiconductor assembly.
• Chemical & Pharmaceutical: Resin synthesis, solvent recovery, and process vent purification.
