Description
Technical field
The utility model relates to three flue-gas cleaning devices of iron and steel enterprise's steel-making converter, relates in particular to three smoke gathering devices of a kind of novel induction type converter.
Background technology
As everyone knows, protection of the environment is the fundamental state policy that must adhere to for a long time, and under the brute force promotion of national policy and the supervision of public opinion, the environmental protection of Jun Dui plant area of each iron and steel enterprise has proposed requirements at the higher level.
The trapping effect of at present traditional steel-making converter secondary flue gas capturing device is unsatisfactory, and a large amount of flue gases can not trap and escape, and have caused the pollution of steelshop and atmospheric environment.
In order to address this problem, domestic and international generally employing is set up three times, roof flue gas dust collecting system the flue gas of escaping is trapped.But the flue gas that is not trapped by secondary flue gas capturing device and escape, in uphill process, constantly entrainments the air of surrounding, and be subject to the impact of crossflow and structures, constantly, to surrounding diffusion, finally form very large exhaust gas volumn.For these flue gases that spread apart of good trapping, not only need to make the cover open area of removing roof dust cover large, and the air quantity that third dedusting system needs is also very large, so not only cause initial cost to increase, and third dedusting systematic running cost is also very high.
Therefore, we need to design three smoke gathering devices of converter of a kind of efficient, low consumption.
Utility model content
Technical problem to be solved in the utility model is to provide three smoke gathering devices of converter of a kind of efficient, low consumption.
The technical scheme that the utility model adopts is: three smoke gathering devices of a kind of novel induction type converter, it comprises the Induced fan that is arranged on converter secondary flue gas capturing device top, the top of described Induced fan is provided with removing roof dust cover, and described removing roof dust cover is provided with the induced exhaust being connected with outside cleaning shaft.
Closer, described Induced fan has a plurality of, is multirow and/or multiple row and arranges.
Closer, described removing roof dust cover is positioned on the roof of power house, and described Induced fan is positioned at power house.
Closer, described removing roof dust cover comprises the swash plate that leans forward, top board, rear panel and two side plates; Described induced exhaust is positioned on top board.
The angle of swash plate and the horizontal direction of leaning forward closer, is 30 °-60 °.
In the utility model, described Induced fan can induce the high-temperature flue gas escaping to concentrate and move upward along set track, effectively suppressing high-temperature flue gas spreads to surrounding, reduce the amount of entrainmenting of flue gas simultaneously, make movement locus and the exhaust gas volumn of flue gas controlled, and final induction enter in removing roof dust cover by induced exhaust the outside cleaning shaft of high-temperature flue gas suction.So not only can reduce the size of removing roof dust cover, corresponding weight also lightens, the air quantity that simultaneously makes outside dust removal process is corresponding reducing also, when improving three flue gas trapping rates, initial cost reduces, working cost is corresponding reducing also, realizes the object of efficient, the low consumption of three smoke gathering devices of converter.Induced fan be installed on removing roof dust cover under, facilitate high-temperature flue gas trapping.Induced fan can be used in combination, and is also for better by flue gas trapping.
The beneficial effects of the utility model are:
1, Induced fan can induce the flue gas escaping to concentrate and move upward along set track, effectively suppresses flue gas and spreads to surrounding, reduces the amount of entrainmenting of flue gas simultaneously, makes the movement locus of flue gas controlled, and final induction enters removing roof dust cover;
2, the size of removing roof dust cover and weight all reduce, and have reduced cost of investment;
3, the air quantity of dust-removal system is reduced, when improving three flue gas trapping rates, initial cost reduces, and working cost also reduces, and has realized that three flue gas trappings are efficient, low consumption object;
4, the utility model is simple in structure, on almost not impact of process for making, is applicable to newly-built and transformation project, can effectively reduce investment and shorten the transformation cycle.
Accompanying drawing explanation
Fig. 1 is the side-looking structural representation of an embodiment of three smoke gathering devices of novel induction type converter.
Fig. 2 is the perspective view of three smoke gathering devices of novel induction type converter.
In figure: 1, Induced fan, 2, removing roof dust cover, 2-1, the swash plate that leans forward, 2-2, top board, 2-3, rear panel, 2-4, side plate, 3, induced exhaust, 4, power house, 5, converter secondary flue gas capturing device, 6, iron ladle, 7, converter.
Embodiment
Below in conjunction with accompanying drawing, further illustrate embodiment of the present utility model.
Referring to Fig. 1 and Fig. 2, three smoke gathering devices of a kind of novel induction type converter, it comprises the Induced fan 1 that is arranged on converter secondary flue gas capturing device 3 tops, directly over described Induced fan 1, be provided with removing roof dust cover 2, described removing roof dust cover 2 comprises the swash plate 2-1 that leans forward, top board 2-2, rear panel 2-3 and two side plate 2-4; Described top board 2-2 is provided with the induced exhaust 3 being connected with outside cleaning shaft.
In the present embodiment, described removing roof dust cover 2 is positioned on the roof of power house 4, and described Induced fan 1 is positioned at power house 4.The angle of described lean forward swash plate 2-1 and horizontal direction is 45 °.
In order to reach better trapping effect, in the present embodiment, described Induced fan 1 has 3, is a line and arranges.Certainly, we can establish a plurality of Induced fans 1 according to actual needs, and allow a plurality of Induced fans 1 be multirow and/or multiple row arrangement, to reach better flue gas trapping effect.
When the work of converter hot metal charging starts, converter 7 tilts to state in Fig. 1, when iron ladle 6 tilts to start, toward 7 while falling molten iron of converter, will produce a large amount of high-temperature flue gas.Converter secondary flue gas capturing device 5 exhausting of starting working now, because collection efficiency is limited, a large amount of flue gases is escaped and is moved upward.Now Induced fan 1 is in opened condition, induce a large amount of flue gases to move upward from Induced fan 1, effectively suppressing flue gas spreads to surrounding, reduce the amount of entrainmenting of flue gas simultaneously, make the movement locus of flue gas controlled, and finally induction enters removing roof dust cover 2, removing roof dust cover 2 is installed on the roof of power house 4, and be connected with induced exhaust 3, induced exhaust 3 is connected with outside cleaning shaft.
Inducing action due to Induced fan 1, the amount of entrainmenting of flue gas reduces, trend to surrounding diffusion has also been subject to inhibition, the air quantity of third dedusting system reduces, when improving three flue gas trapping rates, initial cost reduces, and working cost also reduces, and has realized the object of efficient, the low consumption of three smoke gathering devices.
Should be understood that above-described embodiment is only not used in restriction scope of the present utility model for the utility model is described.In addition should understand, after having read the content of the present invention's instruction, those skilled in the art can make various changes or modifications the utility model, for example, adjust quantity and the spread pattern (being a line three row in this example) of Induced fan 1, adjust the installation site of Induced fan 1, adopt other forms of apparatus for deivation, size and the installation site of adjusting removing roof dust cover 2, these equivalent form of values fall within the utility model appended claims limited range equally.
