AI Technical Summary

Technical Problem

Existing multi-layer plate heat recovery heat exchangers are difficult to clean when used, as impurities adhering to the outer surface of the heat exchange plates cannot be effectively transferred, reducing heat exchange quality and making them less practical.

Method used

A multi-layer plate heat recovery heat exchanger including a cleaning mechanism, a heat exchange mechanism, and a buffer mechanism was designed. The heat exchange plates are flushed by a high-pressure water pump and a high-pressure nozzle, and the flow of heat exchange fluid is buffered by a movable plate and a buffer spring structure to achieve self-cleaning and buffering effects.

Benefits of technology

It effectively reduces the impact of impurities on the outer surface of the heat exchange plate on heat transfer, improves heat exchange efficiency, and extends the service life of the equipment.
