Abstract
A kind of high box bellows structure air cooling wall fire grate, belongs to air cooling wall fire grate field.Including outer panel, column, cold air layer, bellows, grate surface and air compartment；The column side connects outer panel, and another upper lateral part connection cold air layer side, lower part connection bellows side, air compartment and grate surface is arranged in the bellows other side.The utility model bellows top is provided with associated logical cold air layer, a wind part in this way in bellows is blown on grate surface, to carry out reactive combustion with the coal on fire grate segment, another part blows to cold air layer, the heat absorption that furnace wall part is distributed, hot wind is converted to by cold wind, and burner hearth is finally blown into as First air, to reduce thermal loss, boiler efficiency is improved.
Description
Technical field
The utility model is related to air cooling wall fire grate field more particularly to a kind of high box bellows structure air cooling wall fire grates.
Background technology
Fire grate is the component banked up solid fuel in boiler or industrial furnace and be effective burning.Entirely fire grate includes mainly
Two parts of frame and fire grate segment, fire grate segment usually cylinder iron manufacture, and keep necessary ventilation gaps after assembling between piece and piece,
And toward contact, the draft chamber that can adjust air quantity is set below in fire grate, so that air enters fuel bed burning by gap,
Lime-ash after burning-up is manually or mechanical means is discharged.Current fire grate have fixed, mobile, reciprocating, oscillatory type and under
The fire grate that the types such as feeding formula, wherein fixed type grate use is exactly fixed, and coal is placed on fire grate, is passed through from fire grate lower section
Air makes coal combustion, fire grate segment be generally strip or plate, and burner hearth or combustion chamber bottom are fixedly mounted on by the frame of surrounding
Portion.It can only periodically by hand firing and slag tap on this fire grate, so operation labor intensity is big, burning economic effect is also poor,
Be adapted only to the stove such as evaporation capacity of low capacity 0.5 ton/when Industrial Boiler below.Fixed type grate stove is broadly divided into handwarmer
With spreader stoker boiler two types, handwarmer is manually-operated fixed grate grate furnace；Spreader stoker boiler essentially refers to spreader feeder
With a kind of combination of fixed grate.And be furnace brickwork inside existing high box-shaped structure fire grate, lower part is bellows, when work,
It is blown on grate surface again in wind to air compartment in bellows, to carry out reactive combustion with the coal on fire grate segment, works as boiler operatiopn
When the heat that is given out by furnace brickwork just pass to outer panel and dissipate, to waste the energy, reduce boiler effect
Rate.
Utility model content
To solve heat transfer that existing high box-shaped structure fire grate is given out in boiler operatiopn by furnace brickwork to outer
Side plate dissipates, and to waste of energy, the problem of reducing boiler efficiency, the utility model provides a kind of high box bellows structure
Air cooling wall fire grate.
To achieve the above object, the technical solution adopted in the utility model is：A kind of high box bellows structure air cooling wall fire grate,
Including outer panel, column, cold air layer, bellows, grate surface and air compartment；The column side connects outer panel, another upper lateral part
Cold air layer side, lower part connection bellows side are connected, air compartment and grate surface is arranged in the bellows other side.
Further, the cold air layer is connect with bellows, and access is provided between cold air layer and bellows.
Further, it is provided with access between the bellows and air compartment.
Further, the grate surface lower part connects air compartment, and access is provided between grate surface and air compartment.
Further, the cold air layer other side connects furnace wall.
Further, the grate surface connects furnace wall.
Further, it is provided with fire grate segment on the grate surface, fuel is provided on fire grate segment.
Further, the cold air layer setting access connects burner hearth.
The utility model has the beneficial effects that：Bellows top is provided with associated logical cold air layer, in such bellows
A wind part blow on grate surface, to carry out reactive combustion with the coal on fire grate segment, another part blows to cold air layer, will
The heat absorption that furnace wall part distributes, hot wind is converted to by cold wind, and burner hearth is finally blown into as First air, to reduce heat
Loss, improves boiler efficiency.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
1. outer panel in figure, 2. columns, 3. cold air layers, 4. bellows, 5. furnace walls, 6. grate surfaces, 7. air compartments.
Specific implementation mode
A kind of high box bellows structure air cooling wall fire grate, including outer panel 1, column 2, cold air layer 3, bellows 4, grate surface 6
With air compartment 7；2 side of the column connects outer panel 1, and 3 side of another upper lateral part connection cold air layer, lower part connect bellows 4 one
Air compartment 7 and grate surface 6 is arranged in side, 4 other side of bellows.
3 other side of the cold air layer connects furnace wall 5.
The cold air layer 3 is connect with bellows 4, and access is provided between cold air layer 3 and bellows 4, one in bellows 4
Divide wind to enter the heat absorption that cold air layer 3 distributes furnace wall 5, hot wind is converted to by cold wind.
It is provided with access between the bellows 4 and air compartment 7.
6 lower part of the grate surface connects air compartment 7, and access, the part in bellows 4 are provided between grate surface 6 and air compartment 7
Wind reaches grate surface 6 by air compartment 7.
The grate surface 6 connects furnace wall 5.
It is provided with fire grate segment on the grate surface 6, fuel is provided on fire grate segment, reaches the wind and fire grate segment of grate surface 6
On fuel carry out reactive combustion.
The cold air layer 3 is arranged access and connects burner hearth, and hot wind is finally blown into burner hearth as First air.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
It is confined to this, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
