AI Technical Summary
⚠Technical Problem
In existing technologies, a large amount of ammonia needs to be sprayed when mixing with flue gas, resulting in waste of excess ammonia and low mixing efficiency.
⚗Method used
An ammonia spraying device is adopted, which includes a pressure pump, an ammonia water collection unit, a flue gas delivery pipe, an ammonia water primary atomization unit, and an ammonia water secondary atomization unit. Excess ammonia water is collected by the collection seat and atomized again in the ammonia water secondary atomization unit to improve the mixing efficiency.
🎯Benefits of technology
This effectively avoids ammonia waste, increases the number of ammonia spraying sessions, improves the mixing efficiency of ammonia and flue gas, and achieves a more efficient denitrification effect.
