AI Technical Summary

Technical Problem

Existing thermal power flue coolers have difficulties in disassembly and cleaning and leakage, resulting in waste of heat energy and reduced cooling efficiency.

Method used

A thermal power flue cooler is designed, adopting multiple water circuit circulation methods. Through the circulating water pump and cooling shell structure, the staggered setting of cooling pipes and multiple sets of circulating water circuits are realized to avoid overall failure caused by leakage of single cooling pipes, and to clean it in the normal working state of the boiler.

Benefits of technology

It effectively avoids the failure of the cooler caused by the leakage of the cooling pipe, improves energy utilization efficiency, reduces heat energy waste, and avoids frequent disassembly and cleaning, realizing online cleaning.
