Abstract
The utility model relates to a compound inductive upper smoke arrestment hood of a converter for secondary smoke arrestment, wherein a smoke induction casing is connected to the lower side wall of the middle section of the smoke exhaust pipe body, a door-shaped gap is arranged at the bottom end of the front surface of the smoke induction casing, an enclosed knot mobile falling curtain is arranged on the wall body of the smoke induction casing at the top end of the door-shaped gap, flow guiding plates with circular arc shaped sections are arranged between the smoke exhaust pipe body and the inner and outer walls of the smoke induction casing, the central angle of the circular arc is smaller than or equal to 90 degrees, the edges of the bottom end parts of the flow guiding plate are parallel to the bottom end edge of the smoke induction casing, the flow guiding plates are arranged on the two sides of the central line of the enclosed knot mobile falling curtain, the top end of the flow guiding plate on the left side of the central line of the enclosed knot mobile falling curtain points to a smoke exhaust port at the left end of the smoke exhaust pipe body, and the top end of the flow guiding plate on the right side of the central line of the enclosed knot mobile falling curtain points to a smoke exhaust port on the right end of the smoke exhaust pipe body. The utility model is capable of arresting about 95 % of the smoke produced in the process of smelting. Since the hood body is not required to be opened when the molten iron watering, feeding, fettling and temperature measuring and sampling are being carried out, the operating sight of the operator and craneman is not affected.
Description
Technical field
The utility model relates to a kind of capturing device that is used for the steel-making converter secondary smoke, and especially a kind of converter secondary smoke captures with inhaling smoke collection cover on the co-induction.
Background technology
Tradition captures petticoat pipe and can only capture and smelt about 80% of whole process flue gas, captures weak effect, and hot metal charging, reinforced, fettling, thermometric sampling etc. may all need to open cover body, and it is thin to capture cover body, mostly is water-cooling structure, and maintenance workload is big.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of can capture smelt the whole process flue gas about 95%, need not to open the converter secondary smoke capture of cover body with inhaling smoke collection cover on the co-induction when capturing operation such as effective, hot metal charging, reinforced, fettling, thermometric sampling.
The technical scheme that provides according to the utility model, described converter secondary smoke captures with inhaling smoke collection cover on the co-induction, comprise horizontal smoke exhaust pipe body, the stage casing lower wall of smoke exhaust pipe body connects the smoke guide shell body, offer a shape breach in smoke guide shell body front surface bottom, be provided with on the smoke guide shell body wall body of door shape breach apical position that movable joint is moving holds court from behind a screen, between smoke exhaust pipe body and smoke guide shell inside and outside wall body, be provided with section and be circular-arc flow deflector, the central angle of described circular arc is less than or equal to 90 °, the bottom of flow deflector and smoke guide shell body bottom side edge are along concordant, the flow deflector branch is located at the both sides of the moving center line of holding court from behind a screen of movable joint, and the left end smoke outlet of smoke exhaust pipe body is pointed on the moving flow deflector top of holding court from behind a screen the longitudinal midline left side of movable joint, and the right-hand member smoke outlet of smoke exhaust pipe body is pointed on the flow deflector top on the moving longitudinal midline right side of holding court from behind a screen of movable joint.
Between the inside and outside wall of smoke exhaust pipe body and smoke guide shell body, be provided with supporting tube.The moving bottom of holding court from behind a screen of movable joint is higher than a shape breach bottom.
The utlity model has to capture and smelt about 95% of whole process flue gas, captures effectively, hot metal charging, feed in raw material, need not to open cover body during operation such as fettling and thermometric sampling, do not influence operative employee, craneman's operation sight line.
