The number of the transition pipes is 3-5.
The number of the guide plates is 3-4.
The guide plate comprises a first plate and a second plate, one side of the first plate is butted with one side of the second plate, an opening is formed in the other side of the first plate and the second plate, the opening direction is consistent with the flaring direction of the bell-mouth section, and the opening angle between the first plate and the second plate is 40-60 degrees.
The oxygen ring pipe is externally connected with an oxygen inlet pipe.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses before oxygen gets into the air pipe, through a plurality of guide plates, be the turbulent flow at the diffusion of horn mouth section, oxygen passes through the transition pipe of equipartition and the air mixing in the air pipe is even, and efficiency when can improving the hot-blast furnace burning reduces gas consumption, reaches energy saving and emission reduction effect.
