AI Technical Summary

Technical Problem

In existing multi-stage shell-and-tube condensers, the flow path of cooling water in the shell side is short and straight, resulting in limited heat exchange contact time with the tubes and affecting condensation efficiency and effect.

Method used

The cooling water flow path is designed in an S-shape. By setting up a flow buffer and a diffuser, the contact time between the cooling water and the tubes is extended, and the steam velocity is evenly distributed through the diffuser to avoid local overheating or insufficient condensation.

Benefits of technology

It improves condensation efficiency and effectiveness, ensures more thorough heat exchange between cooling water and the tubes, evenly distributes steam flow rate, avoids local overheating, and improves the overall performance of the condenser.
