It send to SCR off-gas treatment sections and carries out primary first-order equation, be then sent to return air mechanism and carry out secondary response, then be delivered to heat exchanger
1, finally it is discharged from exhaust section.
Specifically, air draft mechanism includes main air blower 2, steam trap 3 and exhaust piping 4；Steam trap 3 connects
Between main air blower 2 and exhaust piping 4, exhaust piping 4 is connect with SCR off-gas treatment sections.The exhaust gas of annealed wire is taken out by main air blower 2
It takes and first passes around steam trap 3 for the steam removing in exhaust gas, then enter back into exhaust piping 4, be delivered to from exhaust piping 4
SCR off-gas treatment sections carry out primary first-order equation.
SCR off-gas treatment sections include the first processing pipeline 5, and second processing pipeline 6 and third handle pipeline 7；Wherein,
One processing pipeline 5 is connect with exhaust piping 4, second processing pipeline 6 be connected to the first processing pipeline 5 and third handle pipeline 7 it
Between, third processing pipeline 7 is connect with return air mechanism.Exhaust gas passes through primary first-order equation in the first processing pipeline 5 to third processing pipeline 7
After be delivered to return air mechanism, carry out secondary response.
Return air mechanism includes motor 8, shaft coupling 9, cooler 10, backheat blower 11, intake stack 12 and wind pipe
13；Wherein, one end of shaft coupling 9 is connect with motor 8, and the other end is connect with cooler 10, is in shaft coupling 9 by cooler 10
Bearing cooling, temperature is excessively high and burn out after avoiding bearing from operating for a long time, improves service life.The other end of cooler 10 with
