AI Technical Summary
Technical Problem
In existing technologies, the cooling efficiency of urea nozzles under high-temperature environments has limited room for improvement and cannot meet normal cooling requirements.
Method used
The spray gun nozzle is connected to the surrounding cooling pipe by a thread. High-pressure coolant is introduced through the gap between the external and internal locking threads and the pressurized liquid delivery pipeline to form atomized cooling water to cool the spray gun pipe and the spray gun nozzle.
Benefits of technology
It improves cooling efficiency, avoids affecting combustion inside the furnace, and enhances the cooling effect.

Abstract
This utility model discloses a urea nozzle cooling device, relating to the field of material conveying equipment technology. It includes a spray gun connecting pipe and a spray gun nozzle, with the nozzle fixedly connected to the pipe. A surrounding cooling pipe is sleeved around both the pipe and nozzle, and an inner locking thread is provided on the inner side of the cooling pipe. By providing an outer locking thread and an inner locking thread, the nozzle and the surrounding cooling pipe are threaded together. Because there is a gap between the outer and inner locking threads, when pressurized coolant is injected into the flow chamber through the pressurized liquid conveying pipeline, it is output along the connection between the surrounding cooling pipe and the nozzle. The flowing water independently cools the parts of the spray gun connecting pipe and nozzle near the furnace body. Furthermore, because the cooling water is under pressure when passing through the gap between the outer and inner locking threads, the cooling water injected into the furnace will atomize under pressure. Compared to existing technologies, this improves cooling efficiency without affecting combustion within the furnace.
