Development and Challenges of Heat Exchange Technology in the Coking Industry:

1. Comparison of Traditional Heat Exchanger Types:

   • Shell and Tube Heat Exchangers: Simple structure and strong pressure resistance, suitable for high-temperature and high-pressure conditions. However, they have low heat exchange efficiency, are prone to fouling, and have high maintenance costs. Commonly used in chemical production equipment.

   • Spiral Plate Heat Exchangers: Compact size and high heat exchange efficiency. However, they are non-repairable, have poor pressure resistance, and are susceptible to fouling from medium impurities. Their use in the coking industry is gradually decreasing.

   • Plate Heat Exchangers: Efficient and compact, suitable for clean media. However, they have narrow flow channels, are prone to clogging, and the cost of wide flow channel modifications is high.

2. Innovative Solution: Coaxial Heat Exchanger

   • Technical Highlights:

     • Spiral flow channel design achieves countercurrent heat exchange, improving efficiency by over 30%.
     • Self-cleaning capability through turbulent flow that scours the tube walls, reducing fouling risks.
     • High-pressure adaptability supports complex operating conditions, extending equipment lifespan.

     • 

   • Application Scenarios: Ideal for new projects or upgrading existing equipment.
