AI Technical Summary

⚠Technical Problem

During the operation of existing heat exchangers, solid suspended particulate matter in the flue gas is prone to deposit on the inner or outer surface of the heat exchange tubes, forming a dust layer. This leads to increased heat transfer resistance and flow resistance, affecting heat exchange efficiency and system energy consumption.

⚗Method used

The heat-conducting particles pass through the heat-conducting pipe under gravity and rub against its outer wall to clean up the smoke and dust. Combined with filter screen screening and scraper to remove attached dust, the rotating mechanism achieves self-cleaning. The heat exchange efficiency is improved through the recycling and screening effect of the heat-conducting particles.

🎯Benefits of technology

It effectively cleans the dust and fumes on the surface of the heat pipe, ensuring direct contact between the high-temperature flue gas and the heat pipe, improving the heat exchange effect, solving the problems of heat transfer efficiency reduction and increased flow resistance caused by ash accumulation, and realizing the system's self-cleaning and high energy efficiency.
