Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that described herein
Specific embodiment only in order to explain the present invention, is not intended to limit the present invention.
First embodiment of the invention discloses a kind of desulphurization fume baffle door, as it is shown in figure 1, this baffle door includes one
Housing 1, described housing are stainless steel material, are coated with sulfur corrosion resistant material outside it；At least one axle being arranged on housing
2, when described axle 2 has multiple, it is uniformly distributed along housing 1 between each axle 2；The baffle plate 3 being fixed on axle 2.Described axle head has close
Packing material, by the gap sealing between axle 2 and framework, described airtight and watertight padding material is politef, for damper vanes
The sealing of axle head, prevents smoke spillage.This filler is corrosion-resistant, wear-resisting, self-lubricating, and coefficient of friction is little, good sealing effect.
There is on described axle 2 aperture of multiple equidistant distribution, the penetrating centrage through axle 2 of described aperture, described gear
Plate 3 is rectangular, and rectangle long limit centerline direction has a perforation, and described penetration hole diameter is equal or slightly larger than the diameter of described axle 2,
Described axle 2 can be through the perforation of described baffle plate 3.It is distributed in the perforation of described baffle plate 3 and the aperture position pair on described axle 2
The hole, location answered, when described axle 2 is through the perforation of described baffle plate 3, aperture thereon is corresponding with the hole, location on baffle plate 3.Often
A pair aperture and hole, location are fixed by a screw and nut, the diameter of described screw and hole, described location and the internal diameter of aperture
Equal.So, baffle plate 3 can be fixed with axle 2.
Seeing accompanying drawing 2, at least one end of described axle 2 stretches out after housing 1, and extension is equipped with rocking bar 4.Each axle 2
Rocking bar 4 between there is connecting rod 5, connecting rod 2 by each axle interconnection and realize the linkage of each axle.
Equipped with intake valve, intake valve on the air inlet flange sealing air conducting mouth at described baffle door housing 1 top
Control bar connection sealing air cock drive link 4 and pass through rocking arm after being fixed on the bearing with spherical outside surface of usheing to seat at baffle door housing 1 top
It is connected with connecting rod.Linkage and blade (i.e. baffle plate 3) have good synchronicity.Mechanical linkage is understood due to the existence of sideshake
There is closing not dead phenomenon.
The framework of gas baffle uses integral die or shaped steel to make, and has good strength and stiffness.Protection screen is tied
Structure is considered as eliminating the inconsistent phenomenon of inside and outside change in size that internal-external temperature difference causes.
In the implementation below of the present invention, improved for blade.
First, all damper vanes use streamlined design, and SR is little.Blade is formed around nickel alloy and seals
Sheet, when baffle door is closed, is passed through and reaches the sealing air of 500Pa than maximum pressure in flue residing for baffle plate, reaches to cut off medium
Purpose.
Alternatively, simple mechanical linkage sealing is used can to there is gap increasing, leaf between use a period of time rear blade
The problems such as sheet dislocation, thus cause sealing effectiveness to be deteriorated, therefore, the present invention proposes a kind of improved plan.
As it is shown on figure 3, be provided with sealing strip on two blades, along being provided with the first sealing strip 31 on blade 31,
32 times edges of blade are provided with the second sealing strip 32.Described sealing strip is all in sector, and resilientiy stretchable.So, when sealing,
Two sealing strips extrude mutually, have reached sealing effectiveness, and meanwhile, because using sector structure, sealing strip is occurring elastic deformation
Relatively urine can play sealing function, and the most easily restores to the original state after blade separates.
In order to further reach sealing effectiveness, leaf production is become multi-layer compound structure.As shown in Figure 4, described blade
For three-decker, innermost layer 311 is iron material, has an intermediate layer 312 outside described innermost layer 311, and described intermediate layer 312 is
Carbon steel material, described intermediate layer 312 is coated with innermost layer 311 completely, and outermost layer 313 is corrosion resisting stainless steel material, and outermost layer 313 is complete
Full cladding intermediate layer 312.Corrosion resisting stainless steel is selected to do the outermost layer of blade face panel material, the available sealing air not heated.This
Time, the corrosion of acid condensed fluid produced by baffle plate and smoke contacts surface is undertaken by corrosion resistant plate.In view of outermost layer corrosion resistant
Erosion stainless steel material can produce the most unavoidably and come off or be corroded, and therefore intermediate layer uses ordinary carbon steel to make panel
Material, uses temperature to exceed the sealing air of water dew point, it can be ensured that Non-water-cooled lime set produces at air outlet and baffle blades surface.
It is further preferable that see Fig. 4, it is respectively arranged with cavity 314 at the two ends of described innermost layer, in described cavity 314
Having an electric magnet 315, the electromagnet pole between upper and lower two blades is contrary.When blade needs Guan Bi, described electric magnet
All opening, under the attraction of electric magnet, each blade can produce and attract up and down so that produce mutually pulling force between each blade, so
Its sealing effectiveness can be improved further.It will be clear to one skilled in the art that the electric power system of electric magnet can be arranged on
Outside baffle door.The hollow pipe of a placement wire can be offered on the shaft, one end of described hollow pipe can by a hole with
Described baffle plate (blade) is connected, and the wire of described electric magnet can extend to the outside of axle 2 through described hole along conduit, with confession
Electricity system connects.
The present invention can reach following useful technique effect: the flue gas desulfurization Double-layer blind formula baffle door that the present invention provides
Using single shaft to drive double multiple damper structure, twi-tier blade medium design has fan-shaped sealing strip, by least above flue gas pressure
The sealing air of power 1000Pa is passed through baffle plate, makes to be formed between dual-layered baffle plate to seal air barrier, blocks passing through of flue gas stream.
Baffle door hull outside is designed with linkage, makes each blade of baffle plate open and close in shutter streamlined way, open after optimizing design
Open or close synchronization, it is achieved integration operation.Blade good rigidly, stable and reliable operation, be passed through between blade have certain pressure and
After the sealing air of flow, can effectively completely cut off flue gas stream before and after blade, so that flapper door seal efficiency is 100%.Baffle door
Rotate flexibly under ensureing working condition, without bite phenomenon.Baffle design streamlining structure, can fully reduce the resistance to air-flow
Power.Blade uses composite layered structure, can improve its strength and stiffness.Gas baffle door is carried further by the principle of electric magnet
High sealing effectiveness.
Described above illustrate and describes the preferred embodiments of the present invention, as previously mentioned, it should be understood that the present invention not office
Be limited to form disclosed herein, be not to be taken as the eliminating to other embodiments, and can be used for other combinations various, amendment and
Environment, and can be changed by above-mentioned teaching or the technology of association area or knowledge in invention contemplated scope described herein
Dynamic.And the change that those skilled in the art are carried out and change are without departing from the spirit and scope of the present invention, the most all should be appended by the present invention
In scope of the claims.
