Three-Stage Pre-Filtration
Primary bag filtration, secondary medium-efficiency filtration and tertiary medium-efficiency filtration protect the zeolite rotor.
Dust Collection System
Zeolite Rotor Concentration and Catalytic Combustion System
This zeolite rotor concentration and catalytic combustion system uses three-stage dry filtration to protect the zeolite rotor concentrator. The VOC concentration system concentrates large-volume, low-concentration exhaust into a smaller, higher-concentration stream before catalytic oxidation.
Main Features
Process and Performance Highlights
Zeolite rotor concentration and catalytic combustion system for concentrating large-volume, low-concentration VOC exhaust before catalytic oxidation.
Zeolite-Rotor Concentration
The vertical rotor concentrates organic exhaust and is designed for continuous rotation at 3–4 revolutions per hour.
Hot-Air Desorption
Approximately 200°C hot air desorbs VOCs before the rotor passes through a cooling zone and returns to adsorption.
Heat-Recovery Catalytic Treatment
The concentrated stream is heated to catalytic light-off temperature, purified into carbon dioxide and water vapor, and passed through heat exchangers for energy recovery.
