Description
Technical field
The sealing thermal insulation of boiler is the utility model is related to, more particularly to a kind of flexible sealing for boiler bottom support is protected
Warm device.
Background technology
Gas fired-boiler such as coke-stove gas, blast furnace gas boiler be applied to ironmaking, steel mill, by it in smelting process
Caused coke-stove gas or blast furnace gas are recycled.These Medium and small gas boilers height all in 20-30 rice even
It is higher, the water-cooling wall volumetric expansion from up to down of boiler operatiopn rear hearth, cause water-cooling wall to drive in the generation of water-cooling wall lower header
Bottom offset, and the support furnace wall of boiler bottom can not be movable downwards, will be produced between water-cooling wall and refractory wall very big
Space, gap can leak into part heat smoke.Swelling water is fixed or increased to water-cooling wall lower header by onsite application steel plate at present
Case, the steel plate of fixed dimension can not meet that the basic demand of the uncertain pressure-bearing of water-cooling wall then triggers Plate break, and increase swollen
Swollen water tank adds difficulty of construction because specification volume itself is big, it is necessary to design supporting support body.
The content of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of for the soft of boiler bottom support
Property sealing thermal insulation device.
The utility model is achieved through the following technical solutions：Including water-cooling wall lower header, thermal insulation concrete layer, stove
Wall, it is characterised in that：Comb sealing plate is set on the casing of the water-cooling wall lower header, and the inside edge of the comb sealing plate is set
Put short flexible expansion section to be connected as a single entity, the comb sealing plate and short flexible expansion section are directed around being formed along water-cooling wall lower header
Cavity, sealing band steel is set on the madial wall of the short flexible expansion section bottom, channel-section steel is set on the thermal insulation concrete layer, institute
Sealing band steel insertion channel-section steel to be stated to seal off cavity with extraneous, the water-cooling wall lower header bottom sets long flexible expansion section,
The long flexible expansion section bottom sets sealed bottom plate to support long flexible expansion section, and the sealed bottom plate is fixed on furnace wall
On.
In such scheme, between the short flexible expansion section, comb sealing plate, long flexible expansion section, sealed bottom plate
It is partially filled with insulation material.
In such scheme, the insulation material is alumina silicate fiber felt.
Compared with prior art, its is beneficial for a kind of flexible sealing attemperator for boiler bottom support of the utility model
Effect is：
1. making full use of expansion joint to fully absorb the water-cooling wall of boiler operatiopn rear hearth volumetric expansion amount from up to down, make water
Cold wall free wxpansion；
2. addition sealing plate and channel-section steel solve the sealing problem after bottom support process, avoid air from leaking into burner hearth, subtract
Few boiler exhaust gas heat loss；
3. expansion joint gap reduces radiation loss using insulation material；
4. the present apparatus does not have to design supporting mounting bracket, it is directly mounted on former support furnace wall, reduces construction volume.
Brief description of the drawings
Fig. 1 is a kind of knot of the structural representation of flexible sealing attemperator for boiler bottom support of the utility model
Structure schematic diagram.
In figure：1. water-cooling wall lower header, 2. long flexible expansion sections, 3. alumina silicate fiber felts, 4. sealed bottom plates, 5. combed
Sealing plate, 6. short flexible expansion sections, 7. sealing band steels, 8. channel-section steels, 9. thermal insulation concretes, 10. cavitys, 11. refractory brick, 12. water
Cold wall, 13. furnace walls, 14. spaces.
Embodiment
Protected below in conjunction with the accompanying drawings with the specific embodiment flexible sealing for boiler bottom support a kind of to the utility model
Warm device is further described：
Fig. 1 is a kind of structural representation of spring clearing apparatus for ribbon conveyer of the utility model.In figure, this is soft
Property sealing thermal insulation device, including water-cooling wall lower header, thermal insulation concrete layer, furnace wall, comb is set on the casing of water-cooling wall lower header
Shape sealing plate, the inside edge of comb sealing plate set short flexible expansion section to be connected as a single entity, comb sealing plate and short flexible expansion section
It is directed around forming cavity along water-cooling wall lower header, sealing band steel is set on the madial wall of short flexible expansion section bottom, and insulation mixes
Channel-section steel is set on solidifying soil layer, and sealing band steel insertion channel-section steel seals off cavity with extraneous.Water-cooling wall lower header bottom sets length
Flexible expansion section, long flexible expansion section bottom set sealed bottom plate to support long flexible expansion section, and sealed bottom plate is fixed on
On furnace wall.Insulation material is partially filled between short flexible expansion section, comb sealing plate, long flexible expansion section, sealed bottom plate.
Insulation material is alumina silicate fiber felt.
This flexible sealing attemperator is rational in infrastructure, and water-cooling wall 12 expands from top to bottom after boiler operatiopn, water-cooling wall
Lower header 1, comb sealing plate 5 are from inactive state to bottom offset, and thermal insulation concrete 9, the transfixion of refractory brick 11, are so transporting
Very big space 14 will be produced after row between water-cooling wall 12 and refractory wall 11, part heat smoke is leak at space 14 and enters cavity
10, now short flexible expansion section 6 absorb the displacement from water-cooling wall 12, comb sealing plate 5, sealing band steel 7 and channel-section steel circle 8 by
The extruding three downward to water-cooling wall is sealed, and the heat smoke leak into space 14 is kept off within cavity 10, serves sealing
Effect.The heat that alumina silicate fiber felt 3 is brought to the heat smoke being stored in cavity 10 simultaneously obstructs, and prevents under water-cooling wall
Header 1 is directly radiated by heat smoke, serves the effect of insulation.Water-cooling wall lower header 1 is to after bottom offset, long flexible expansion
Section 2 also absorbs displacement simultaneously, ensures that sealed bottom plate 4 remains to play a part of sealing in former resting position.
This flexible sealing attemperator is ingenious to utilize original furnace binding, solve water-cooling wall and water-cooling wall lower header to
Under all displacements the problem of, prevent because expand limit produce internal stress, cause security incident；Sealing structure solves boiler
Heat loss due to exhaust gas, while insulation material reduces radiation loss, improves the thermal efficiency of boiler.Optimization design of the present invention, structure
Simply, it is simple and direct practical flexible sealing attemperator.
It is described above, only it is preferred embodiment of the present utility model, not the utility model is made any formal
Limitation, although the utility model is disclosed above with preferred embodiment, but be not limited to the utility model, it is any ripe
Know professional and technical personnel, do not departing from the range of technical solutions of the utility model, when the method using the disclosure above and
Technology contents make a little change or are modified to the equivalent embodiment of equivalent variations, as long as being without departing from the utility model technology
The content of scheme, any simple modification made according to the technical essence of the utility model to above example, equivalent variations with
