Zeolite Rotary Concentrator + RTO
Time of issue:
Sep 15,2025
Zeolite Rotor Concentrator + RTO Project for Renowned Automotive OEM
▎Project Background
• Treatment Capacity: 80,000Nm³/h low-concentration exhaust gas (VOCs: 150–300mg/m³)
• Core Challenge: Meeting stringent DB42/1539-2019 standard (non-methane hydrocarbons ≤20mg/m³) for surface coating emissions
▎Technical Solution
· Three-Stage Filtration: G4+F7+F9 dry filters achieve ≥98% particulate removal, extending zeolite rotor lifespan to >8 years
· 20× Concentration: Boosts VOCs to 3,000mg/m³, enabling RTO self-sustaining combustion without auxiliary fuel
· Closed-Loop Thermal System: 95% waste heat recovery for rotor desorption, cutting total energy consumption by 42%
▎Outcomes
· Environmental Compliance: Emission concentration stably ≤15mg/m³ (12-month monitoring), 99.2% VOCs removal
· Economic Benefits: Annual savings of ¥680K in natural gas costs + 1,200 tons steam from waste heat recovery
· Industry Recognition: Awarded 2025 Hubei "Industrial Exhaust Treatment Demonstration Project"
