Description
Technical field
The present invention relates to a kind of dust arrester, particularly relate to a kind of smelting converter flue dust dust arrester installation.
Background technology
To smelting converter produce flue dust process reclaim, prior art is all adopt bag collection or cyclone dust removal, also has to reach better effect, also coupling flue dust spraying and sprinkling evaporation dedusting.As: on July 18th, 2007, disclosed in Chinese utility model patent Authorization Notice No. CN2924453Y, a kind of furnace dust spraying-evaporating-cooling cloth-bag dust-removing device is made up of air-introduced machine, sack cleaner and spraying and sprinkling evaporation cooler, is connected in series between air-introduced machine, sack cleaner and spraying and sprinkling evaporation cooler.But this structure is used for smelting converter, the tail gas handled by spraying and sprinkling evaporation cooler, containing a large amount of water vapour, is easy to blocking cloth bag and other are joined after entering sack cleaner, cause duster system to lose efficacy, cloth bag consumption is large; The water content of raw materials for metallurgy own is large simultaneously, and when beginning blow-on is smelted, converter dust moisture vapor is many, and along with the process of smelting procedure advances, flue dust moisture vapor is by how many, and therefore the duty of spraying and sprinkling evaporation cooler is also extremely unstable.
Summary of the invention
The invention provides a kind of smelting converter flue dust dust arrester installation that can be applicable to the change of flue dust moisture vapor, can produce expeditiously.
The present invention adopts following technical scheme:
A kind of smelting converter flue dust dust arrester installation, is made up of dust gathering arrester, sack cleaner, spray deduster and air-introduced machine; Dust gathering arrester is placed in above smelting converter exhaust opening; Dust gathering arrester, sack cleaner, to be connected between two by the first airduct, the second airduct, the 3rd airduct successively between spray deduster and air-introduced machine; The horizontal segment position of the first airduct that described dust gathering arrester is connected with sack cleaner also arranges a triplet commutation device, and the smoke subchannel of this triplet commutation device is parallel on the second airduct that sack cleaner is connected with spray deduster through bypass airduct.
Described triplet commutation device is made up of fume inlet passage, smoke main channel and smoke subchannel, and fume inlet passage is communicated with being switched respectively by a two-way motor-driven valve sheet in valve body between smoke main channel or smoke subchannel; Also humidity sensor is established in fume inlet passage, the detection signal of humidity sensor drives through control circuit and connects bidirectional electric valve block, switch fume inlet passage when making the smoke moisture of fume inlet passage large to communicate with smoke subchannel, smoke moisture hour switches fume inlet passage and communicates with smoke main channel.
During smelting converter blow-on of the present invention, because large the produced high-temperature smoke of the water content of raw materials for metallurgy own is under the effect of air-introduced machine, collected by dust gathering arrester and enter the first airduct, switch turnover cigarette passage through triplet commutation device, then enter spray deduster collect flue dust through bypass airduct, the second airduct.When smelting converter intensification melting reaction is stablized, high-temperature smoke water content declines; The detection signal of humidity sensor drives through control circuit and connects bidirectional electric valve block, switches fume inlet passage and communicates with smoke main channel; Now, collected by dust gathering arrester and enter the first airduct, enter sack cleaner and gather dust, remaining cigarette discharged by sack cleaner, then enters spray deduster through the second airduct and collect flue dust further.
Compared with prior art, tool of the present invention has the following advantages:
1. apply the present invention to administer smelting converter high-temperature smoke, its discharge can reach 50mg/Nm
3below;
2. during bypass blow-on produce the large high-temperature smoke of water content, make cloth bag not produce dew condensation phenomenon, reduce resistance, reduce power consumption, general reduce power about 30%, and sack cleaner is lightened the burden, and decrease the investment of sack cleaner;
3. system can regulate selection to enter spray deduster and sack cleaner according to the moisture content of high-temperature smoke automatically.

Fig. 1 is suction type structural representation of the present invention.
Reference numeral is: 1 dust gathering arrester; 2 sack cleaners; 3 spray dedusters; 4 air-introduced machines; 5 smelting converters; 6 first airducts; 7 second airducts; 8 the 3rd airducts; 9 triplet commutation devices; 10 bypass airducts; 11 bidirectional electric valve blocks.
Detailed description of the invention
With reference to Fig. 1, a kind of smelting converter flue dust dust arrester installation, is made up of dust gathering arrester 1, sack cleaner 2, spray deduster 3 and air-introduced machine 4, and dust gathering arrester 1 is placed in above smelting converter 5 exhaust opening; Dust gathering arrester 1, sack cleaner 2, to be connected between two by the first airduct 6, second airduct 7, the 3rd airduct 8 successively between spray deduster 3 and air-introduced machine 4; The first airduct 6 horizontal segment position that described dust gathering arrester 1 is connected with sack cleaner 2 also arranges a triplet commutation device 9, and the smoke subchannel of this triplet commutation device 9 is parallel on the second airduct 7 that sack cleaner 2 is connected with spray deduster 3 through bypass airduct 10.Described triplet commutation device 9 is made up of fume inlet passage, smoke main channel and smoke subchannel, and fume inlet passage is communicated with being switched respectively by a two-way motor-driven valve sheet 11 in valve body between smoke main channel or smoke subchannel; Also humidity sensor is established in fume inlet passage, the detection signal of humidity sensor drives through control circuit and connects bidirectional electric valve block 11, switch fume inlet passage when making the smoke moisture of fume inlet passage large to communicate with smoke subchannel, smoke moisture hour switches fume inlet passage and communicates with smoke main channel.
During smelting converter 5 blow-on, because large the produced high-temperature smoke of the water content of raw materials for metallurgy own is under the effect of air-introduced machine 4, collected by dust gathering arrester 1 and enter the first airduct 6, switch turnover cigarette passage through triplet commutation device 9, then enter spray deduster 3 through bypass airduct 10, second airduct 7 and collect flue dust.When smelting converter 5 heat up melting reaction stablize time, high-temperature smoke water content decline; The detection signal of humidity sensor drives through control circuit and connects bidirectional electric valve block 11, switches fume inlet passage and communicates with smoke main channel; Now, collected by dust gathering arrester 1 and enter the first airduct 6, enter sack cleaner 2 and gather dust, remaining cigarette discharged by sack cleaner 2, then enters spray deduster 3 through the second airduct 7 and collect flue dust further.
