Description
Technical field
The utility model relates to flue gas processing devices more particularly to a kind of electric furnace flue gas to trap roof cover.
Background technique
Electric furnace is in smelting process, and furnace charge moment under arcing is heated and melts, the iron atom for being evaporated out
And the oxygen in the carbon and atmosphere in scrap iron and steel forms the oxide and carbon dioxide of a certain amount of iron, under the action of hot pressing,
It overflows in the place such as the gap of these dust between the gap and bell and furnace body between electrode and bell.If to electric arc furnaces flue dust
Effective control measure are not taken, will seriously pollute workshop and plant environment, influence the health of worker and surrounding resident.
Currently, flue gas trapping mode used by domestic improvement electric furnace steel making flue gas mainly has " four holes+roof cover " and " half
Enclosed hood " or " enclosed hood ".The electric furnace that they are applied to common power has preferable trapping effect, but still has several drawbacks
Place, wherein the trapping effect of roof cover is poor, and energy consumption is high；Although half-sealed cover and enclosed hood trapping effect are preferable, to charging
It can not be trapped with the secondary flue gas of operating conditions situation such as tappings.If being applied to uhp electric arc furnace and using carbonyl spray gun, molten iron
The electric furnace of the new processes such as hot charging is then since electric furnace flue gas temperature increases, exhaust gas volumn increases, and shortcoming is more prominent, roof cover
Effect can further decline；Half-sealed cover and enclosed hood are then difficult to adapt to the problem that flue-gas temperature is excessively high and exhaust gas volumn is excessive.Such as
Fruit is solved with the method for improving processing air quantity, it is clear that is uneconomic.Meanwhile half-sealed cover and enclosed hood be in charging, two
Secondary flue gas still can not trap.
+ four hole of roof cover (while closing and smelting area's workshop), the paved set scheme of this form can both trap each work of electric furnace
The flue gas that generates under the conditions of condition does not influence smelting process, and can improve furnace top equipment operating condition, has very big superiority.But
Be, it have it is clearly disadvantageous, as dedusting energy consumption is high；It smelts area's flue gas in workshop to diffuse, dustfall content is big on table, blast-furnace man and row
Lathe work environment is not improved well.
Utility model content
The applicant is directed to disadvantage mentioned above, has carried out Improvement, provides a kind of electric furnace flue gas trapping roof cover.
Technical solution used by the utility model is as follows:
A kind of electric furnace flue gas traps roof cover, the left and right deflector including electric furnace two sides are arranged in, and is arranged on the electric furnace
Overhead traveling crane, overhead traveling crane connect electric furnace charging bell, are located above overhead traveling crane right above electric furnace and roof cover is arranged, the interior setting of the roof cover is equal
Fabric swatch, and smoking pipeline is connected above roof cover, roof cover is located at the high central negative pressure in the intermediate low periphery of setting below uniform board
Adjustment disk, the center negative pressure adjustment disk are connect with the lifting driver part on roof cover, the roof cover arranged on left and right sides difference
Left and right side is set and rotates wing plate, the steel ladle of tapping is arranged in lower section on front side of electric furnace, rotation wing plate in setting front side on front side of roof cover.
As a further improvement of the above technical scheme:
The lifting driver part is that driving cylinder can drive cylinder.
The beneficial effects of the utility model are as follows: the electric furnace flue gas traps roof cover, it can not only trap electric furnace steel making
The flue gas of overall process is smelted, flue gas when including charging, tapping improves flue gas trapping efficiency, and does not influence smelting process, behaviour
Make and repairs, less influence overhead traveling crane operation, and interior smoke evacuation can be cooperated while trapping flue gas.

Specific embodiment
With reference to the accompanying drawing, illustrate the specific embodiment of the present embodiment
As shown in Figure 1 to Figure 3, the present embodiment electric furnace flue gas trap roof cover, including be arranged in 1 two sides of electric furnace a left side,
Right deflector 2,3, is arranged overhead traveling crane 4 on electric furnace 1, and overhead traveling crane 4 connects electric furnace and charges bell 41, and 4 top of overhead traveling crane is located at right above electric furnace 1
Roof cover 5 is set, uniform board 51 is set in roof cover 5, and connect smoking pipeline 52 above roof cover 5, roof cover 5 is located at uniformly distributed
The high central negative pressure adjustment disk 53 in intermediate low periphery is set below plate 51, negative pressure region is effectively extended out, most by 5 suction of roof cover
Strong part can be expanded by central compression to surrounding and be held together cigarette range, reduce the diffusion of 1 flue gas of electric furnace；Core negative pressuren zone has simultaneously
Effect decline forms three-dimensional ring and inhales effect so that negative pressuren zone is closer to gold tobacco control area, and changes suction airstream direction, will
The cigarette ability of holding together of roof cover 5 extends out extension comprehensively by traditional horizontal direction change to vertical direction, and negative pressure area expands significantly
Greatly, so that roof cover 5 into cigarette speed faster, central negative pressure adjustment disk 53 is connect with the lifting driver part 6 on roof cover 5, rise
Dropping driving part 6 is driving cylinder meeting drive cylinder, and left and right side rotation wing plate 71,72 is respectively set in 5 arranged on left and right sides of roof cover,
The steel ladle 8 of tapping is arranged in 1 front side lower section of electric furnace, and setting front side rotates wing plate 73 on front side of roof cover 5.
Electric furnace flue gas trapping roof cover in use, electric furnace 1 when being smelted, the left and right side rotation wing plate 71,
72 and front side rotation wing plate 73 be in closed state, and at this time lifting driver part 6 driving end be in stretching state, central negative pressure
Adjustment disk 53 is in extreme lower position, and flue gas, when electric furnace 1 carries out input and output material, left and right side rotary wings can be trapped by roof cover 5
Plate 71,72 and front side rotation wing plate 73 are in the open state, and expand roof cover 5 catches gas face, and lifting driver part 6 is driven at this time
Moved end is in contraction state, and central negative pressure adjustment disk 53 is in extreme higher position, can by roof cover 5 trap flue dust, at this time in
Centre negative pressure adjustment disk 53 is located at 4 top of overhead traveling crane, does not influence the movement charging of overhead traveling crane 4.
Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model
Range is referring to claim, and without prejudice to the basic structure of the utility model, the utility model can make any shape
The modification of formula.
