Abstract
The utility model relates to a spraying, cooling and dust removal device for a converter and a door-shaped cover. The spraying, cooling and dust removal device comprises a converter, a door-shaped cover, a water and gas supply device, and an automatic control device, wherein a gas-phase nozzle is formed in front of the door-shaped cover and is connected with the water and gas supply device through a water and gas supply pipe; and the water and gas supply device is connected with the automatic control device through a line. When the converter is fed with materials, the automatic spraying control device starts the water and gas supply device after receiving a feeding signal to cool the smoke generated in the feeding process in a spraying manner, thereby achieving primary dust removal, lowering the smoke temperature sucked by a second dust removal system and suppressing dust. The spraying, cooling and dust removal device can reduce the leakage and the radiation degree of high-temperature smoke so as to improve the operation environment and meet the requirement of environmental protection. In addition, the device can improve the smoke trapping efficiency during feeding the converter under the condition of no increasing air quantity of the secondary dust removal system.
Description
Technical field
The utility model relates to the final dusting of metallurgy industry steel mill converter steelmaking, particularly a kind of converter door shape cover spray cooling device for reducing dust.
Background technology
Steel mill's secondary BOF dedusting system mainly is to gather dust discharging after the sack cleaner purifying treatment is up to standard by the door shape cover of being located at top, converter stokehold at present.Because modern steel-making rhythm is accelerated, output increases, and the factors of using such as waste steel quality difference, flue gas when making the converter hot metal charging burns above fire door, like this, the flue-gas temperature that is captured by dust-removal system rises to about about 500 ℃ by 230 ℃, causes original dust-removal system to can't bear burden, causes environmental pollution.
For example 250t～300t converter, traditional final dusting flue gas trapping mark condition air quantity is about 390,000Nm
3/ h (230 ℃), the operating mode air quantity is 720,000m
3/ h.Because above factor, the flue-gas temperature that is captured by dust-removal system rises to about 500 ℃ by 230 ℃, makes former flue gas trapping ability drop (need the operating mode air quantity about 1,100,000m
3/ h), cause flue gas to escape, cause environmental pollution.
The utility model content
In order to improve above traditional final dusting mode, task of the present utility model provides a kind of converter door shape cover spray cooling device for reducing dust, and it has solved, and flue-gas temperature rises the flue gas trapping ability drop in traditional final dusting, cause flue gas to escape, cause environmental pollution problems.
Technical solution of the present utility model is as follows:
A kind of converter door shape cover spray cooling device for reducing dust, it comprises converter and door shape cover, it also comprises water supply and air feeder and automatic control device;
Before the described door shape cover gas phase shower nozzle is housed, the gas phase shower nozzle is connected to by water supply and supply air line and supplies water and air feeder, and supplying water is connected with automatic control device by circuit with air feeder.
Described water supply and air feeder are equipped with water supply main valve and air feed main valve.
On the described water-supply line valve is housed.
On the described supply air line valve is housed.
When converter is reinforced, the spraying automatic control device receives the reinforced signal of converter, start water supply and the flue gas that the reinforced process of converter is produced is adopted the spray pattern cooling with air feeder, to reach the purpose of preliminary depositing dust, reduce the flue-gas temperature that the final dusting system sucks, play certain dust suppression effect simultaneously.
Adopt converter door shape cover spray cooling device for reducing dust of the present utility model; both reduce the temperature of secondary BOF dedusting system flue gas, reduced the final dusting exhaust gas volumn again, and can alleviate the excessive of high-temperature flue gas and radiation degree; improve operating environment, meet requirement on environmental protection.
Converter door shape of the present utility model cover spray cooling device for reducing dust is applicable to that the converter of metallurgical steel mill converts the dedusting in the iron process, both applicable to the final dusting to newly-built converter project, also applicable to the technological transformation to existing secondary BOF dedusting system system.After implementing spray cooling device for reducing dust of the present utility model, can be under the condition that does not increase the final dusting systematic air flow, the flue gas trapping efficient when the raising converter is reinforced.
Description of drawings
Accompanying drawing is the enforcement synoptic diagram of a kind of converter door shape cover spray cooling device for reducing dust of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of converter door shape cover spray cooling device for reducing dust of the present utility model is installed on converter 1 and door shape cover 2, and it mainly is made up of gas phase shower nozzle 3, water supply and air feeder 5, automatic control device 6 and pipeline.
Before gas phase shower nozzle 3 is installed in a shape cover 2.Gas phase shower nozzle 3 is connected to by water supply and supply air line and supplies water and air feeder 5.Supply water and be connected with automatic control device 6 by circuit with air feeder 5.
Water supply is equipped with water supply main valve 52 and air feed main valve 51 with air feeder 5.Penstock is housed on water-supply line, air valve is housed on supply air line.
When converter 1 hot metal charging, send and convert the iron signal, receive by automatic control device 6, automatic control device 6 control water supply and air feeder 5 actions, pressurized air and water are gaseous state with supply air line from gas phase shower nozzle 3 by supplying water and spray.After converting the iron end, converter 1 is sent and is converted the iron end signal, and automatic control device 6 controls are supplied water and air feeder 5 is closed, and finish spray process.
Converter door shape of the present utility model cover spray cooling device for reducing dust is to the technological transformation of existing secondary BOF dedusting system system the time, mainly take: in suitable position, converter stokehold the two-phase atomizer is set, the water supply air demand is controlled by automatic control device.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim conversion, the modification of the foregoing description.
