Customize Anodically Protected For Acid Cooler
Jiangsu Carpe Diem Ocean Equipment Co., Ltd. specializes in manufacturing durable heat transfer steel equipment designed to withstand extreme conditions. The Anode Protection Sulfuric Acid Cooler represents their flagship solution for industrial acid processing applications.
Technical Overview
While appearing as a standard shell-and-tube heat exchanger, this equipment incorporates advanced engineering specifically designed to manage heat in highly corrosive sulfuric acid environments. It effectively cools 93% to 99% sulfuric acid used in drying and absorption processes within contact plants. Standard equipment rapidly deteriorates in these conditions, making anodic protection technology essential for longevity.
Operating Principle
The system utilizes anodic protection technology, maintaining steel components at a precise electrical potential within the "passive zone" to prevent corrosion. This requires three key components: cathode assemblies (either rod-style through the unit or pin-style in nozzles), reference electrodes for monitoring, and a potentiostat controlling DC current.
  • Protective Barrier Formation: Applied DC current initiates the formation of an invisible oxide film that covers all acid-exposed surfaces, reducing corrosion rates by orders of magnitude.
  • Continuous Monitoring: The system constantly monitors the potential between steel and electrodes, making immediate adjustments to maintain the optimal passive zone and prevent both active corrosion and transpassive conditions.
  • Robust Construction: Heavy-duty rod baffles provide dual functionality—preventing tube vibration while enhancing heat transfer efficiency.
Key Benefits
  • Superior Corrosion Resistance: Anodic protection enables stainless steel to perform reliably in environments where it would normally deteriorate rapidly.
  • Durable Protective Film: The stable oxide layer provides continuous protection without degradation, preventing metal erosion.
  • Enhanced Heat Transfer: Optimized turbulent flow and efficient heat exchange surfaces maximize thermal performance while minimizing energy loss.
  • Reliable Operation: Consistent performance with remote monitoring capabilities reduces unexpected shutdowns and maintenance issues.
  • High Temperature Capability: Safe operation at 160°C and higher allows for effective waste heat recovery and improved process efficiency.
