Heat exchange process:
High-temperature fluid (such as steam) flows in the shell side, while low-temperature fluid (such as liquid) flows in the tube side.
Heat is conducted through the wall of the bayonet tube (including both the outer and inner tubes), causing the temperature of the fluid in the tube side to rise, thus achieving heat exchange.
Turbulence-enhanced heat transfer:
The special structure of the bayonet tube induces complex flow patterns within the tube, such as increased turbulence, effectively reducing thermal resistance and enhancing the heat transfer coefficient.
Compared to traditional straight-tube heat exchangers, it can enhance heat transfer efficiency by 30%-50% and achieve significant heat transfer with a relatively small temperature difference.
Anti-scaling performance:
The flow state of fluid inside the bayonet tube makes it difficult for dirt to deposit on the tube wall, making it particularly suitable for handling fluids prone to scaling (such as aqueous solutions containing impurities or high-concentration solute fluids).
The anti-scaling performance reduces the frequency of cleaning and lowers maintenance costs.
