Acid Gas Treatment for Photovoltaic Manufacturing For Suzhou Ates Sunshine Power Technology
Challenge:
Suzhou Ates Sunshine Power, a leading NASDAQ-listed photovoltaic manufacturer, required a reliable solution to treat acid gas exhaust generated during solar cell production. Key requirements included:
• Handling complex acid mist composition (HF, HNO?, H?SO?) with strict emission limits
• Ensuring long-term stability with minimal maintenance in continuous production environment
• Integrating seamlessly with existing PECVD and wet process lines
• Meeting both national GB16297-1996 standards and internal environmental compliance targets
Our Solution:
Chaori Environmental designed a customized FRP purification tower (CRBF series) tailored to photovoltaic industry exhaust characteristics.
Key features include:
• Proprietary spray system with low-pressure, high-flow spiral nozzles for optimal gas-liquid contact and zero clogging
• Custom PP packing with enhanced dispersion performance for efficient pollutant absorption
• High-efficiency mist eliminator to prevent liquid carryover and ensure clean discharge
• Corrosion-resistant FRP construction engineered for long service life in harsh chemical environments
• Automated control system with pH/ORP monitoring for consistent compliance and optimized operation
Results:
The system was engineered to deliver:
• Stable acid mist removal performance meeting GB16297-1996 Class II standards
• Low-maintenance operation with non-clogging nozzle design and accessible service points
• Compact footprint suitable for space-constrained PV facilities
• Reliable long-term operation supporting 24/7 production schedules
