Embodiment
Below in conjunction with accompanying drawing, further illustrate embodiment of the present utility model.
Referring to Fig. 1-Fig. 3, a kind of Novel steelmaking converter secondary flue gas capturing device, it comprises and is arranged on the air intake resistance adjustable Electrically operated gate 2 of steel, slag transport passage 1 both sides and is arranged on the fume trap cover 3 in converter 8, described fume trap cover 3 is communicated with outside cleaning shaft by airduct 5, and described outside cleaning shaft is connected with extractor fan; Described fume trap cover 3, described air intake resistance adjustable door 2, described converter 8, the iron ladle 7 that is arranged on described converter 8 tops, anti-smoke-box 4 form a space for sealing relatively; Described converter 8 is placed in described anti-smoke-box 4.
In the present embodiment, described fume trap cover 3 comprises front panel 3-1, top board 3-2 and rear panel 3-3, described front panel 3-1, top board 3-2 and rear panel 3-3 are connected to form the hollow cell body that a below has opening in turn, and the two ends of hollow cell body are all connected with described airduct 5.
In order to reach better trapping effect, described front panel 3-1 and rear panel 3-3 are measure-alike, and described opening is over against the dispersal direction of described secondary flue gas.
In order effectively to have reduced the dedusting air quantity of system, described air intake resistance adjustable Electrically operated gate 2 is connected to form by the unit wing plate 2-1 of a plurality of activities, and described unit wing plate 2-1 is connected with transmission rig by rotating shaft, transmission rig drives rotating shaft to rotate, the rotation of rotating shaft realizes the rotation of unit wing plate 2-1, thereby realizes the wild air quantity that single cell wing plate 2-1 controls turnover air intake resistance adjustable Electrically operated gate 2.In the present embodiment, a plurality of unit wing plate can be used as an integral body, then by a rotating shaft, is connected with transmission rig; Each unit wing plate also can connect respectively a rotating shaft, then by the rotation of rotating shaft, is controlled respectively the rotation of each unit wing plate.
