AI Technical Summary
The independent operation of the traditional cement kiln bypass ventilation system and the bypass ash washing system results in high equipment redundancy, large floor space, high infrastructure and operation and maintenance costs, and the discharge of high-temperature ash increases system heat consumption and reduces production.
The bypass ventilation system is coupled with the water washing system. Through the combination of decomposition furnace, heat exchanger, dust collector and washing tower, high-temperature flue gas desalination is achieved. Sodium chloride and potassium chloride remain in gaseous state and enter the washing tower for spray water washing, which simplifies system equipment and reduces heat consumption.
The system equipment is simplified, the floor space and operation and maintenance costs are reduced, while the infrastructure and operation costs are reduced, and the deep desalination of flue gas and the resource utilization of ash are achieved.
