Converter is formed around converter enclosed hood, and the side of converter is rotationally provided with a shape iron making petticoat pipe, door shape iron making
The height of petticoat pipe is converter open top when converter turns to the angle for receiving molten iron to side, and the lower section of converter is along transport
The direction of advance of the ladle trolley of ladle is rotationally provided with tapping petticoat pipe and petticoat pipe of slagging tap successively, and roof smelts petticoat pipe and is located at and turns
Stove turns to vertical converter open top when smelting position.
Described converter secondary flue gas capturing device, it is characterized in that：Door shape iron making petticoat pipe, tap petticoat pipe and slag tap petticoat pipe this
Three is right-angled trapezium, and, at 45 °~60 °, the straight waist of this three is designed with rotating for the oblique waist of this three and the angle on base long
Tapping petticoat pipe and slag tap located at outside and the opening of oblique Lumbar nearly converter on axle, the base long of the right-angled trapezium of door shape iron making petticoat pipe
The base long of the right-angled trapezium of both petticoat pipes is located at top and the nearly ladle of oblique Lumbar.
When the utility model is used, converter enclosed hood implements daily masking to converter；When converter to charging across inclining connecing
During the molten iron toppled over by ladle, door shape iron making petticoat pipe close under to upright position, topple over the flue gas that is produced during molten iron from door shape iron making
Petticoat pipe and roof charging petticoat pipe discharge；Converter receives and turn to after molten iron the vertical position that smelts and start steel-making, is produced in smelting process
Raw flue gas smelts petticoat pipe discharge from roof；After the completion of smelting, now ladle is transported to converter lower section, while tapping petticoat pipe and to go out
Slag petticoat pipe all turns to horizontal level, and converter is rotated again topples over molten steel to ladle, topples over the flue gas that is produced during molten steel from tapping
Petticoat pipe is discharged, and after molten steel is toppled over and finished, is excluded the flue gas produced during slag and is discharged from petticoat pipe of slagging tap.As door shape iron making petticoat pipe, go out
Steel petticoat pipe and petticoat pipe this three of slagging tap all using right-angled trapezium, can more effectively, thoroughly collect flue gas.
The utility model is the improvement to steelwork converter secondary flue gas capturing device, and period is produced according to different process,
Different petticoat pipes are taken to combine, the flue gas that different parts are produced during to converter smelting is trapped, can be by the trapping of converter gas
Efficiency brings up to more than 95%.
The beneficial effects of the utility model are：Simple structure, easy for installation, catch rate is high, safety and environmental protection.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
The utility model is further illustrated below by way of specific embodiment.
Embodiment 1
A kind of converter secondary flue gas capturing device, including converter 11, ladle 12, converter enclosed hood 1, door shape iron making petticoat pipe 2,
Tapping petticoat pipe 3, petticoat pipe 4, roof of slagging tap charging petticoat pipe 5 and roof smelt petticoat pipe 6, as shown in figure 1, concrete structure is：
Converter 11 is rotatably arranged in converter bay 13, and across 14 located at the side of converter bay 13, ladle 12 passes through ladle for charging
Chassis is located at charging on 14；
Converter 11 is formed around converter enclosed hood 1, and the side of converter 11 is rotationally provided with a shape iron making petticoat pipe 2, door
The height of shape iron making petticoat pipe 2 is the top of the opening of converter 11 when converter 11 turns to the angle for receiving molten iron to side, converter 11
