    Zeolite Rotor RTO Waste Gas Treatment Equipment: Technical Analysis and Industry Application Guide

    I. Technical Principles and Core Advantages

1. Zeolite Rotor Concentration Technology
   • Working Principle: Utilizes the adsorption-desorption characteristics of hydrophobic zeolite molecular sieves to concentrate large-volume, low-concentration VOCs waste gas into small-volume, high-concentration waste gas. The rotor is divided into adsorption, desorption, and cooling zones, achieving continuous operation through rotation.
   • Technical Advantages:
     • High-Efficiency Concentration: Concentration ratio can reach 10-40 times, significantly reducing the scale of subsequent treatment equipment.
     • Temperature and Humidity Resistance: Zeolite material can withstand temperatures above 200°C and relative humidity up to 90%, adapting to complex working conditions.
     • Long Lifespan: Zeolite module lifespan typically reaches 8-10 years, with low maintenance costs.
     • Anti-Clogging Design: For particulate matter such as paint mist, large-pore zeolite or pre-stage multi-level filtration (e.g., G4+F7 two-stage dry filters) is adopted.
2. RTO Thermal Oxidation Technology
   • Working Principle: Recovers heat through ceramic regenerative beds, heating the waste gas to 760-850°C, oxidizing VOCs into CO₂ and H₂O.
   • Technical Advantages:
     • High Purification Efficiency: VOCs removal rate ≥95%, meeting strict emission standards.
     • High Heat Recovery Efficiency: Regenerative bed heat recovery rate can reach over 95%, reducing energy consumption.
     • Self-Sustaining Combustion: When treating high-concentration waste gas, little or no auxiliary fuel is required.
3. Combined Process Synergy
• Energy Consumption Reduced by 40-60%: After the zeolite rotor concentrates the waste gas, the RTO treatment scale is reduced, and the RTO high-temperature flue gas can be used for rotor desorption, achieving thermal energy recycling.
• Improved Stability: The rotor's buffering effect stabilizes waste gas concentration fluctuations, providing stable inlet conditions for the RTO.
• Strong Adaptability: Capable of treating various VOCs such as benzene series, esters, and ketones, unaffected by changes in composition.

II. Industry Application Scenarios and Cases
