Regenerative Catalytic Oxidation System for VOC Treatment with Automated Process and High-Performance Adsorption Material

Key Features of the System:

1. Fully Automated Process

   • The entire system achieves automated purification and desorption, ensuring no secondary pollution during operation.

2. Two-Stage Dust Filtration

   • A dual-stage pre-filtration system is installed before the adsorption bed, enhancing purification efficiency and extending the adsorption device’s service life.

3. High-Performance Adsorption Material

   • Utilizes specially molded honeycomb activated carbon or zeolite molecular sieves with 8–10 times the density of conventional fiber adsorbents.

   • Capable of adsorbing organic solvents up to 25% of its total weight before regeneration.

   • Benefits: Long service life, low system resistance, and high purification efficiency.

4. Advanced Catalytic Combustion

   • Precious metal catalysts (palladium & platinum) on honeycomb ceramics ensure:

     • Low resistance, high activity, and long lifespan

     • Low decomposition temperature & short desorption preheating time

     • Energy-efficient operation with excellent stability

   • Maintains self-sustained combustion at 2000ppm organic waste gas concentration.

   • Catalytic combustion efficiency exceeds 97% with high conversion rates and stable performance.

5. Waste Heat Recovery for Energy Savings

   • Hot air (from catalytic combustion waste heat) serves as the desorption medium.

   • Concentrated organic waste gas is fed back into the catalytic burner for purification, eliminating additional energy needs and significantly reducing operating costs.

6. PLC Automated Control System

   • Ensures safe, stable, and reliable operation with full automation, including:

     • Automatic catalytic combustion heating

     • Program-controlled desorption process

     • Real-time temperature feedback for precise desorption control
