Abstract

The utility model provides a smoke cleaning, dust extraction and cooling smoke cover of a titanium slag furnace. The smoke cover is characterized in that the smoke cover comprises a cylinder cover (1), smoke evacuation pipes (2), a taper-shaped dust sliding plate (3), a cylinder dust shielding sleeve plate (4), water-cooled curtain pipes (5) and air-cooled annular cavities (6); an annular pipe is connected with horizontal pipes, so a water cooling pipe network formed via the connection of an annular pipe and a horizontal pipe is arranged on the lower side face of an upper cover plate (7) of the cylinder cover and is communicated with the water-cooled curtain pipes (5); and a plurality of air outlets (63) are arranged in a conical cylinder (62) in a distributed manner. During work, air blows across the air outlets (63) in the air-cooled annular cavities (6), so an air curtain cover is formed, and CO gas, smoke and dust are prevented from being diffused outside and allowed to be fully burned; and the gas, the smoke and the dust discharged outwards are cooled by the water cooling pipe network and the water-cooling curtain pipes (5), so effects of smoke cleaning, dust extraction and cooling are achieved, and CO discharge is reduced.

Description

The clean cigarette of titanium slag stove, dedusting, cooling petticoat pipe

Technical field

The utility model relates to smelting equipment.The particularly clean cigarette of titanium slag stove, dedusting, cooling petticoat pipe.

Background technology

The smelting of the Rare Metals Materials such as titanium slag (melting) refining, all can produce the pernicious gases such as the fuel gas such as a large amount of carbon monoxide and carbon dioxide, simultaneously with a large amount of dust.

Traditional titanium slag stove petticoat pipe is semi-enclosed, petticoat pipe consists of cylindrical cap 1 and smoke exhaust pipe 2, petticoat pipe is arranged on body of heater top, this semi-enclosed titanium slag stove petticoat pipe, there is in use following deficiency: the 1st, the fuel gas in flue gas, because anoxic can not get completing combustion, enters in cleaner and easily produces and explode.The 2nd, when flue gas is large, will below cylindrical cap, outwards fill the air contaminated environment.The 3rd, flue-gas temperature is high, has reduced the 30%-50% in service life of cleaner.

Utility model content

The purpose of this utility model is to improve for the shortcoming deficiency of above-mentioned prior art, and the titanium slag stove petticoat pipe of a kind of clean cigarette, dedusting, good cooling effect is provided.

The clean cigarette of the utility model titanium slag stove, dedusting, cooling petticoat pipe, comprise cylindrical cap 1, smoke exhaust pipe 2, taper sliding dust plate 3, cylinder dust-break cage plate 4, water-cooled curtain pipe 5, air-cooled ring cavity 6, the upper end of cylinder dust-break cage plate 4 is welded and fixed and is connected with the upper cover plate 7 of cylindrical cap 1, form the smoke output chamber A of cylinder dust-break cage plate 4 outer shrouds and cylindrical cap 1 interior interannular, the corresponding smoke output chamber A of smoke exhaust pipe 2 distributes and offers connection, on the downside of the upper cover plate 7 of cylindrical cap 1, be provided with the water cooling pipe network that ring pipe 71 and transverse pipe 72 are connected to form, on the bottom of cylindrical cap 1, be welded to connect taper sliding dust plate 3, the water-cooled curtain pipe 5 consisting of some water pipe row examples is set on the medial surface of cylinder dust-break cage plate 4, water-cooled curtain pipe 5 is through taper sliding dust plate 3, the ring pipe of the water cooling pipe network on the upper end of water-cooled curtain pipe 5 and cylindrical cap upper cover plate 7 downsides leads to, the bottom of water-cooled curtain pipe 5 is provided with endless tube 51 each water-cooled curtain pipe 5 is communicated with, in the outside of the water-cooled curtain pipe 5 of taper sliding dust plate 3 downsides, be fixedly connected with ring cylinder 61, between the bottom of this Huan Tong61 bottom and taper sliding dust plate 3, be connected with cone cylinder 62 and form air-cooled ring cavity 6, air-cooled ring cavity 6 is connected air intake by blast pipe 10 with air blast, on cone cylinder 62, be distributed and be provided with some air outlets 63, its blowing forms air curtain,

The clean cigarette of the utility model titanium slag stove, dedusting, cooling petticoat pipe, when titanium slag stove smelting (melting) refining is produced, the flue dust gases such as a large amount of CO that produce in body of heater T, because forming wind curtain type hood cover, air outlet 63 blowings on air-cooled ring cavity 6, and blow in the middle part of body of heater, make CO gas and flue dust can not outwards fill the air diffusion, the large quantity of air being blown into is burnt CO gas fully, central part between body of heater and petticoat pipe forms a flue dust post moving upward simultaneously, when hot dust touches the water cooling pipe network that ring pipe 71 on cylindrical cap upper cover plate 7 downsides and transverse pipe 72 be connected to form, carried out cooling for the first time, then dust carries out baffling and enters smoke output chamber A after by water-cooled curtain pipe 5 under dust-break cage plate 4 effect, dust is further cooling by water-cooled curtain pipe 5.In this course, cooling the falling of flue dust of larger particles, along taper sliding dust plate 3, glide, and taken back in burner hearth and be again smelted by air outlet 63 blowings on air-cooled ring cavity 6, thereby reach clean fume and dust, cooling, flue-gas temperature is low, and CO gas content is few, has effectively prevented that flue gas from entering generation blast in cleaner.
