Abstract
The invention discloses a method for removing dust on a roof of a steel plant, which comprises the following steps: a partition plate is used for separating an iron adding span and an oxygen lance blowing span of the converter; directly connecting a roof dust removal pipeline with the iron adding cross dust collection hood; compiling a special roof dust removal valve control program; starting an accident button such as splashing on a picture of a main control room of the converter, opening all roof dust removal valves of the splashing converter, and closing the roof dust removal valves of other converters; and after a period of time, the roof dedusting valves of all the converters are recovered to be normal. The method aims to provide a novel steel plant roof dedusting method, and the converter accident state is intensively controlled through a roof dedusting system of the steel plant, if: a large amount of smoke dust generated during splashing, slag overflowing, iron spraying and the like is treated in a centralized way through the roof dust removal system, the problem that the use of the dust removal air quantity is uneven is solved, the working efficiency of the roof dust removal system is improved, and the atmospheric quality in a steel-making factory is obviously improved.
Description
Technical field
The present invention relates to metallurgy industry to make steel field of Environment Protection, more particularly in converter generation splash, the slag that overflows, spills the accidents such as iron
When how to reduce atmosphere pollution in factory building, the method for improving steel mill removing roof dust system effectiveness.
Background technology
Steel mill can produce substantial amounts of smoke-dust in converter smelting, although there is secondary dedusting system to reduce dust pollution,
But still some smoke-dust is discharged into air from steel mill roof, especially when converter occurs splash, the slag that overflows, spills the accidents such as iron,
A large amount of smoke-dusts are blown out from steel-making factory building, and traditional removing roof dust system can not purify a large amount of smoke-dusts, and dust pollution is serious.
The removing roof dust system of steel mill, smoke-dust four dissipates elegant caused by converter, it is impossible to centralized collection processing, moreover,
In general removing roof dust systematic air flow disperses, when volume of smoke produces, it is impossible in time siphons away a large amount of ash-laden gas, causes serious
Factory building in atmosphere pollution.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of method of novel steelmaking factory removing roof dust, pass through centralized Control
Steel mill removing roof dust system, concentrate under converter accidents state, such as：Splash, the slag that overflows, a large amount of smoke-dusts caused by when spilling iron etc.
Focused on by removing roof dust system, it is uneven to solve the problems, such as that dedusting air quantity uses, improves the work of removing roof dust system
Make efficiency, hence it is evident that improve the air quality in steel-making factory building.
The method of steel mill removing roof dust of the present invention, comprises the following steps：
Converter iron making across and oxygen rifle blowing across being separated with dividing plate；
Removing roof dust pipeline is directly connected with iron making across dust gathering arrester；
Write machine type roof special for power station dust removing valve control program；
Start " emergency button such as splash " on converter master control room picture, open all removing roof dust valves of splash converter,
Close the removing roof dust valve of other converters；
The removing roof dust valve of all converters is recovered normal after a period of time.
The method of steel mill removing roof dust of the present invention, wherein described a period of time refer to 3 minutes.
The method of steel mill removing roof dust of the present invention, wherein the control program is set as inciting somebody to action farthest during daily converter smelting
The converter oxygen gun at end across removing roof dust valve open, when operating personnel click on " emergency button such as splash " when, control program start,
The removing roof dust valve of other converters is closed, the dust removing valve for only retaining the converter that splash occurs is opened, and the time continues 3 minutes, 3 points
Recover daily smelting state after clock.
The method of steel mill removing roof dust of the present invention, it is to break through conventional thought first, by the air quantity collection of removing roof dust system
Middle use, when generation volume of smoke is excessive, removing roof dust systematic air flow focuses on the converter that splash occurs, and improves removing roof dust system
The efficiency of system；Second, converter iron making is separated across being blown with oxygen rifle across with dividing plate, volume of smoke caused by converter splash obtains
Shunting, can be collected by dust excluding hood respectively, and no longer four dissipate and elegant cause to pollute in factory building；Third, in master control room operation screen
Upper increase " emergency button such as splash ", works out dedicated program, is uniformly coordinated the removing roof dust valve of 15 converters, is easy to post personnel
Operation.
The invention will be further described below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the flow chart of the method for steel mill removing roof dust of the present invention.
Embodiment
As shown in figure 1, the method for steel mill removing roof dust of the present invention, comprises the following steps：
Converter iron making across and oxygen rifle blowing across being separated with dividing plate；
Removing roof dust pipeline is directly connected with iron making across dust gathering arrester；
Write machine type roof special for power station dust removing valve control program；
Start " emergency button such as splash " on converter master control room picture, open all removing roof dust valves of splash converter,
Close the removing roof dust valve of other converters；
The removing roof dust valve of all converters is recovered normal after a period of time.
The method of steel mill removing roof dust of the present invention, wherein described a period of time refer to 3 minutes.
The method of steel mill removing roof dust of the present invention, wherein the control program is set as inciting somebody to action farthest during daily converter smelting
The converter oxygen gun at end across removing roof dust valve open, when operating personnel click on " emergency button such as splash " when, control program start,
The removing roof dust valve of other converters is closed, the dust removing valve for only retaining the converter that splash occurs is opened, and the time continues 3 minutes, 3 points
Recover daily smelting state after clock.
The present invention is uniformly coordinated 15 converter roofs of control using the program of a set of special control removing roof dust system valve
Dust removing valve, increase special " emergency button such as splash " in the terminal of every converter, division board is installed between converter bay, by converter
Iron making across with oxygen rifle blowing across separate, by removing roof dust pipeline directly with converter iron making across dust gathering arrester link together, compile
Write machine type roof special for power station dust removing valve control program, when program setting is daily converter smelting by the converter oxygen gun of distalmost end across roof remove
