AI Technical Summary

Technical Problem

Existing plate heat exchangers are prone to blockage during seawater desalination due to the accumulation of suspended solids and the precipitation and crystallization of calcium and magnesium ions, which affects heat exchange efficiency and equipment stability.

Method used

The system uses a liquid guide plate and a baffle ring to form a vortex to separate fine particles, a gas convection port to remove air bubbles, a compressor to dilute the seawater ion concentration, and an ultrasonic cleaning head to emit high-frequency sound waves to remove scale. The spacing between the plates is adjusted by a rolling wheel to create a water hammer effect to assist cleaning.

Benefits of technology

It effectively prevents scaling and clogging, improves heat transfer efficiency, reduces system energy consumption, ensures stable equipment operation, and has a cleaning efficiency higher than chemical cleaning.
