AI Technical Summary
The existing roasting equipment lacks an effective pretreatment process when treating HW17 surface treatment waste liquid, resulting in insufficient reaction and difficulty in meeting increasingly stringent environmental emission standards.
A roasting device including a waste heat recovery unit, an inclined staggered roasting mesh, spray pipes and spray heads was designed. By pre-treating the waste liquid and recovering the heat from the high-temperature flue gas, the residence time of the waste liquid is extended, improving the roasting effect. The material discharge is controlled by sealing baffles and regulating plates to ensure sealing and stability.
It improves the roasting effect and energy utilization rate, ensures the adequacy and safety of waste liquid treatment, meets environmental emission standards, and reduces energy consumption.
