Description
Technical field
The present invention relates to iron and steel enterprise's steel-making converter secondary flue gas purification facility, relate in particular to a kind of steel-making buffer-type converter secondary flue gas capturing device.
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, each iron and steel enterprise all has higher requirement to plant area's environmental protection.
At present traditional steel-making converter secondary flue gas capturing device can not be efficiently, low consumption catch the flue gas producing in converter production process, caused to a certain extent the pollution of steelshop and atmospheric environment, the while has also consumed a large amount of energy.
In order to improve collection efficiency, generally adopt at present the method that improves system dust removing air quantity both at home and abroad.Although improved to a certain extent the collection efficiency of converter secondary flue gas, improve systematic air flow, corresponding dust removal installation capacity must expand, and not only causes investment of equipment to increase, and working cost also increases greatly, does not meet the related request that national energy-saving reduces discharging.At present, trapping converter secondary flue gas how efficient, low consumption has become a domestic and international ubiquitous difficult problem.
Find by a large amount of research and practice, a large amount of secondary flue gas is by the gap escape between crane crossbeam and secondary flue gas fume trap cover, and this gap is to prevent in crane crossbeam moving process and the secondary flue gas fume trap cover safe distance arranging that bumps.
Summary of the invention
The present invention is mainly for the existing above-mentioned technical problem of prior art, and a kind of buffer-type converter secondary flue gas capturing device of efficient, low consumption is provided.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of buffer-type converter secondary flue gas capturing device, comprises the effuser, the bolster that are provided with gas collection mouth; Described effuser is by elastomeric element and bolster mechanical connection, and the opening of effuser is aimed at converter mouth.
Further, bolster is similar to the opening external form of effuser, bolster is fastened on effuser, cover part opening, make remaining opening aim at converter mouth, connect bolster and effuser by elastomeric element, when elastomeric element deforms, bolster makes effuser port area become large or dwindle simultaneously.
Further, the movable header board that bolster is inverted L shape; Described effuser is rectangle chamber, on bottom surface, rectangle chamber and a side, is respectively equipped with a mouth, and two mouths constitute jointly opening, and the two ends in rectangle chamber are communicated with airduct respectively; Described movable header board covers the mouth on side, rectangle chamber on one side, and movable header board the other side is fixedly connected with rectangle chamber end face by spring.
Further, on the item face of rectangle chamber, be also provided with retaining plate, spring one end is connected with retaining plate, and the other end is connected with one side of movable header board.
Further, movable header board and rectangle chamber end face touching position are provided with railroad.
The invention has the advantages that, in the time that crane crossbeam arrives working position, bolster can fully block the space between crane crossbeam and effuser, and from then on passage is excessive to stop secondary flue gas.Prove through a large amount of research and practices, secondary flue gas is mainly by the space escape (bump with the header board of dust excluding hood body for preventing in crane crossbeam moving process, stay certain safe distance) between crane crossbeam and the header board of dust excluding hood body.When crane crossbeam shakes or when error displacement and bolster produce collision, bolster is squeezed under the effect of spring, kicking motion backward, not affect the normal work of crane.In the time that crane crossbeam leaves movable header board, under the effect of spring, the position before movable header board can be returned to and be extruded.
Accompanying drawing explanation
The A-A sectional view that accompanying drawing 2 is Fig. 1.
The B-B sectional view that accompanying drawing 3 is Fig. 1.
The dust excluding hood body construction schematic diagram that accompanying drawing 4 is buffer-type converter secondary flue gas capturing device of the present invention.
In figure: the movable header board of 1-, 2-rectangle chamber, 3-railroad, 4-telescoping side plate, 5-coupling device, 6-spring, 7-bolster, 8-airduct, 9-crane crossbeam, 10-iron ladle, 11-converter.
Embodiment
In Fig. 1,2,3,4, a kind of buffer-type converter secondary flue gas capturing device, comprises the effuser, the bolster that are provided with gas collection mouth; Bolster is the movable header board 1 of inverted L shape; Described effuser is rectangle chamber 2, on 2 bottom surfaces, rectangle chamber and a side, is respectively equipped with a mouth, and two mouths constitute jointly opening, and the two ends in rectangle chamber 2 are communicated with airduct 8 respectively; Movable header board 1 covers the mouth on 2 sides, rectangle chamber on one side, make the mouth on bottom surface can aim at the fire door of converter 11, movable header board 1 the other side is by one end of coupling device 5 linking springs 6, the other end of spring 6 is fixedly connected with the retaining plate 7 of rectangle chamber 2 end faces, movable header board 1 is provided with railroad 3 with rectangle chamber 2 end face touching positions, when movable header board 1 slides with respect to rectangle chamber 2 end faces, guarantee that movable header board 1 straight line line is moving simultaneously and be not offset to reduce resistance.
Principle of work: under normal operation, in the time that crane crossbeam 9 arrives predetermined work position, movable header board 1 just in time contacts and do not collide with crane crossbeam 9.
When crane crossbeam 9 is because shaking or when error displacement and movable header board 1 bump, bolster is squeezed under the effect of spring 6, kicking motion backward, not affect the normal work of crane crossbeam 9, in the first embodiment, railroad 3 can reduce the resistance of motion of movable header board 1 and keep movable header board 1 translational motion not to be offset.
Now, converter 11 has tilted to state in Fig. 2, when iron ladle 10 tilted to start toward 11 times of falling molten iron of converter, will produce a large amount of high-temperature flue gas, now aim at the opening of converter 11 fire doors, airduct 8 is taken cigarette away (dust excluding hood body keeps motionless when in running order), because the bolster of dust excluding hood body tightly contacts with crane crossbeam 9 under the effect of spring 6, effectively block the main escape route of secondary flue gas, improved greatly the collection efficiency of secondary flue gas; In the time that crane crossbeam 9 leaves movable header board 1, under the effect of spring 6, the position before movable header board 1 can be returned to and be extruded.Telescoping side plate 4 is along with the motion of movable header board 1 can launch or shrink.
Above-described embodiment is only not used in and limits the scope of the invention for the present invention 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 present invention, for example, adjust the quantity of spring 6, adopt multi-form buffer gear (being spring 6 in this example), adopt multi-form telescoping side plate 4, movable header board 1 adopts the unit of different quantities to combine (being 5 unit in this example) spring that each unit is corresponding to differ and be decided to be one, be likely two, or more.These equivalent form of values fall within the application's appended claims limited range equally.
