Research on High Efficiency Utilization System of Distillation Furnace Waste Heat Based on Multi stage Heat Exchange and Dynamic Dust Removal

In response to the problems of low flue gas purification efficiency and incomplete waste heat recovery in traditional distillation furnace waste heat utilization systems, this paper designs a waste heat utilization device that integrates dynamic dust removal and two-stage heat exchange. Through theoretical analysis and engineering practice verification, the system can achieve a flue gas dust removal rate of ≥98%, increase the waste heat recovery rate to 82%, and significantly reduce industrial energy consumption and pollution emissions.
