AI Technical Summary
In existing technologies, the high-temperature flue gas generated during the activated carbon carbonization process is not recycled for waste heat, resulting in low energy utilization and heat recovery rates.
A waste heat recovery and treatment device for high-temperature flue gas from activated carbon carbonization is designed. Through multiple heat exchange tanks and flue gas treatment towers arranged in sequence, heat exchange is carried out using heat exchange tubes to recover and treat the waste heat in the high-temperature flue gas. The flue gas finally enters the flue gas treatment tower for further treatment.
It has achieved effective recovery and treatment of waste heat from flue gas, improved energy utilization and heat recovery rate, and significantly enhanced flue gas treatment effect.
