A CAS-OB dedusting device, which belongs to the technical field of metallurgical dedusting, and consists of a lower dust collector hood (1), a CAS hood lifting opening (2), a CAS hood (3), an upper dust collector hood (4), a dust absorbing opening (5), a dust absorbing opening (6), a mixed channel (7), an air seal (8), a blanking pipe (9) and an OB gun (10), wherein the lower dust collector hood (1) is arranged at the lower part of the operating platform, the upper and the lower parts of the CAS hood lifting opening (2) are mounted on the upper dust collector hood (4) and the lower dust collector hood (1) respectively, and dust absorbing openings are formed on both the upper part of the upper dust collector hood (4) and the mixed channel (7), and the air seal (8) is mounted on the mixed channel (7). The utility model has the advantages that fume produced in processing molten steel can be effectively collected, and the fume enters the upper dust collector hood through the CAS hood lifting opening on the operating platform, and as the dust absorbing openings are arranged on the top part of the dust collector hoods, the fume and dust can be conveyed to the purification system by utilizing fully the characteristic of the fume that the fume moves upward.
Description
Technical field
The utility model belongs to metallurgical dedusting field, and a kind of CAS-OB cleaning apparatus particularly is provided, and is used for the CAS-OB stove and handles molten steel process high-effective dust-removing, is applicable to the CAS-OB stove dedusting of metallurgy industry.
Background technology
Existing CAS-OB furnace foundation does not originally have dedusting, and part adopts the dedusting of tremie pipe top, because the dust suction bore is subjected to the restriction of CAS cover, flue dust does not have collecting hood, and dust removing effects is very poor.A hello a large amount of flue gas that operation produces that fall preceding deslagging of CAS cover and later stage can't be collected purification, consequently handle and smolder in the molten steel process seriously, and the influence operation also pollutes environment in the time of seriously.
Summary of the invention
The purpose of this utility model is to provide a kind of CAS-OB cleaning apparatus, adopts two suction ports, has solved the problems referred to above; To handle the flue gas that produces in the molten steel process by the suction port at dust gathering arrester and top up and down and siphon away and purify, with the protection environment, the raising economic and social benefit.
The utility model is by following dust gathering arrester, and CAS covers companionway, the CAS cover, and last dust gathering arrester, suction port, suction port, the hybrid channel, sealing gland, tremie pipe and OB rifle are formed; Following dust gathering arrester is installed in the bottom of service platform, the CAS companionway install dust gathering arrester and following dust gathering arrester up and down respectively, on the top and hybrid channel of last dust gathering arrester (OB rifle and blanking are shared) open suction port simultaneously; (OB rifle and blanking are shared) installation sealing gland on the hybrid channel.
The bottom of service platform ladle mouth over against the zone install under dust gathering arrester, the horizontal direction section is rounded vertically than the high 300-500mm in ladle upper edge for following dust gathering arrester following, diameter is than the big 100-500mm of ladle back cut diameter.
Service platform CAS cover companionway internal diameter guarantees that than the big 600-1000mm of CAS cover external diameter the flue gas of dust gathering arrester collection can enter dust gathering arrester smoothly down.
Last dust gathering arrester is the rounding tubular, and high 1-2m covers the companionway that CAS covers; The top suction port diameter 500-1000mm of last dust gathering arrester, hybrid channel suction port diameter 400-800mm.
The outside diameter of passage 400-800mm of OB rifle, tremie pipe external diameter 300-500mm.
Suction port of the utility model is on the hoist trunk of OB rifle.In addition, dust gathering arrester of next installation on CAS furnace operating platform is collected back top suction port by last dust gathering arrester with flue gas and is entered purification system.Last dust gathering arrester is split type, can keep in repair tremie pipe after taking flange apart.Enter purification system, effective purification of realization flue dust after by last dust gathering arrester and play dust gathering arrester flue gas being collected.To handle the flue gas that produces in the molten steel process by the suction port at last dust gathering arrester and play dust gathering arrester and top and siphon away and purify, to protect environment, the raising economic and social benefit.
Advantage of the present utility model is, the flue gas that the molten steel treating processes produces can effectively be collected, and flue gas covers the dust gathering arrester that companionway enters top by the CAS on the service platform, and suction port is at the top of dust gathering arrester, make full use of the characteristic that flue gas moves upward, flue dust is sent into purification system.
Description of drawings
Fig. 1 is a structural representation of the present utility model.Wherein, following dust gathering arrester 1, CAS covers companionway 2, CAS cover 3, last dust gathering arrester 4, suction port 5, suction port 6, hybrid channel 7, sealing gland 8, tremie pipe 9, OB rifle 10.
Embodiment
Below in conjunction with accompanying drawing concrete enforcement of the present utility model is elaborated.
As shown in the figure, novel C AS-OB cleaning apparatus described in the utility model is by following dust gathering arrester 1, and CAS covers companionway 2, CAS cover 3, and last dust gathering arrester 4, suction port 5, suction port 6, hybrid channel 7, sealing gland 8, tremie pipe 9 and OB rifle 10 combine.
Specifically, following dust gathering arrester is installed in the bottom of service platform, and the horizontal direction section is rounded vertically than the high 300-500mm in ladle upper edge for dust gathering arrester following, and diameter is than the big 100-500mm of ladle back cut diameter.Service platform CAS cover companionway internal diameter guarantees that than the big 600-1000mm of CAS cover external diameter the flue gas of dust gathering arrester collection can enter dust gathering arrester smoothly down.Last dust gathering arrester is the rounding tubular, and high 1-2m covers the companionway that CAS covers.Suction port is opened at the top of last dust gathering arrester, diameter 500-1000mm.OB rifle outside diameter of passage 400-800mm, tremie pipe external diameter 300-500mm.Sealing gland is sealed the flue gas in the hybrid channel, prevents that it is by OB rifle passage with filling tube is suitable for reading outwards emerges.
Following dust gathering arrester, CAS cover companionway and go up dust gathering arrester inside thermal insulation material all is installed, two suction ports are worked simultaneously, guarantee that flue dust that each stage of each position produces all is collected to enter purification system, reach good dust removing effects.
