The implementation principle of the refractory hood in the embodiment of the application is as follows: when the flue gas needs to be guided to move through the flue, the flue gas is guided between the two refractory wall bodies 1 and the water cooling pipe 2, and then cooling water is introduced into the water cooling pipe 2. Therefore, in the process that the flue gas moves in the flue, the cooling pipe can continuously cool the flue gas.
After the flue gas flows into the flue, the flue gas can drive the fan blades 41 to rotate, and the fan blades 41 can drive the flue gas with lower temperature, which is close to one side of the cooling pipe, to move downwards in the rotating process, so that the flue gas with higher temperature below can move upwards to cool; on the other hand, the fan blades 41 rotate to drive the plurality of moving pipes 43 to move back and forth so as to accelerate the cooling water in the water cooling pipe 2, so that the water cooling pipe 2 can keep a lower temperature continuously so as to realize the cooling process of the flue gas in the flue.
And because the temperature of the water-cooled tube 2 is lower, and the surface of the water-cooled tube 2 is smoother than that of the refractory wall 1, dust and impurities in the smoke are difficult to adhere to the water-cooled tube 2, and therefore the occurrence of damage phenomenon of the top of the smoke hood due to erosion in the long-time use process is reduced.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
