Blast furnace blower device

Abstract

A blast furnace blower device includes a body, a flow guidance structure and a cooling module. The body is hollow inside. The body includes an inlet area, an outlet nozzle area, and a fuel nozzle area. The fuel nozzle area is located between the outlet nozzle area and the inlet area, and a channel is formed from the inlet area to the outlet nozzle area. The flow guidance structure is deployed continuously or discontinuously along an inner wall of the body. The flow guidance structure is located between the fuel nozzle area and the outlet nozzle area. The flow guidance structure has a nozzle distance range along an axial direction of the body to the outlet nozzle area. The cooling module is located outside the body.

         2 . The blast furnace blower device according to  claim 1 , wherein a range of the nozzle distance range is between 1/2L and 1/6L, and L is a length of the body. 
     
     
         3 . The blast furnace blower device according to  claim 2 , wherein the nozzle distance range is between 20% and 50% of the range. 
     
     
         4 . The blast furnace blower device according to  claim 1 , wherein the flow guidance structure protrudes from the inner wall of the body. 
     
     
         5 . The blast furnace blower device according to  claim 1 , wherein the flow guidance structure is integrally formed with the inner wall of the body or is disposed separately. 
     
     
         6 . The blast furnace blower device according to  claim 1 , wherein a nozzle angle is provided between the fuel nozzle area and the body. 
     
     
         7 . The blast furnace blower device according to  claim 6 , wherein a range of the nozzle angle is between 0 degrees and 60 degrees. 
     
     
         8 . The blast furnace blower device according to  claim 7 , wherein the nozzle angle is degrees. 
     
     
         9 . The blast furnace blower device according to  claim 1 , further comprising:
 a powder introduction component connected within the body.   
     
     
         10 . The blast furnace blower device according to  claim 1 , wherein the inlet area is used for introducing an oxygen, and the fuel nozzle area is used for directing a methane into the channel. 
     
     
         11 . The blast furnace blower device according to  claim 1 , wherein the fuel nozzle area is a nozzle orifice of the body, and the nozzle orifice is connected to a fuel pipe. 
     
     
         12 . The blast furnace blower device according to  claim 1 , wherein the flow guidance structure is an annular groove surrounding the body. 
     
     
         13 . The blast furnace blower device according to  claim 12 , wherein the annular groove has a round corner. 
     
     
         14 . The blast furnace blower device according to  claim 1 , wherein the flow guidance structure has a flow guidance depth, and the flow guidance depth is formed by recessing a peripheral surface of the body. 
     
     
         15 . The blast furnace blower device according to  claim 1 , wherein an interval range of the flow guidance depth is between 0.05D and 0.2D, and D is the pipe diameter of the body.
