AI Technical Summary
In existing industrial exhaust gas denitrification systems, ammonia delivery pipelines are prone to blockage due to crystallization and particulate matter accumulation. Traditional heating devices cannot adapt to changes in operating conditions, resulting in energy waste and partial failures.
By combining multi-segment zoned heating units with temperature sensors, the heating power is dynamically adjusted through real-time monitoring of pipeline temperature, flow rate, and differential pressure. Combined with PID algorithms and differential pressure change rate to determine blockage risk, adaptive control is achieved.
It enables precise control of the temperature throughout the pipeline, reduces energy consumption, prevents blockages, ensures stable system operation, reduces production accidents, and supports maintenance without interrupting production.
