In, heating boiler is pulverized-coal fired boiler, and using coal dust as fuel, the lime-ash after coal dust firing is mainly oxide, such as CaO, SiO2、
Al2O3Deng, lime-ash is in powdery in most cases, or with the presence of small clinker, coalescence can occur after contacting with water for lime-ash, still
It is floated on the water surface since density is small.With continued reference to Fig. 1, submerged slag conveyor 3, submerged slag conveyor are provided with below heating boiler
3 include the chains 32 that fill the shell 31 of liquid and be arranged in shell 31, is provided with scraper plate on chain 32, in the present embodiment,
Liquid in shell 31 is water, and cost is relatively low, convenient for obtaining.The other end of deslagging device extend into the water surface hereinafter, on the one hand right
Deslagging device is sealed, and cold wind is avoided to enter in the burner hearth of heating boiler, influences the working efficiency of heating boiler, another party
Face makes lime-ash contact and cool down with water.
Specifically, the slag removal of heating boiler are as follows: the lime-ash generated after the coal dust firing in heating boiler burner hearth is fallen
Enter into dry bottom hopper 4, the lime-ash in subsequent dry bottom hopper 4 is entered in shell 31 by deslagging device, and lime-ash coagulates after contacting with water
And it is finally taken out of outside submerged slag conveyor 3 by the scraper plate that chain 32 drives.
Fig. 2 is the front view of the deslagging device of heating boiler provided in this embodiment.Referring to Fig. 2, present embodiments provide
A kind of deslagging device, the deslagging device include slag dropping tube 1 and stirring structure 2.Wherein, 1 one end of slag dropping tube is slagged tap with taper
Mouthful, the other end is connected to the dry bottom hopper 4 of heating boiler, and the direction of dry bottom hopper 4 is directed toward gradually in the cross-sectional area edge of taper slag notch
Reduce.Rabbling mechanism 2 is set in taper slag notch, and part-structure is located at the water surface in submerged slag conveyor 3 hereinafter, can incite somebody to action
Lime-ash in taper slag notch is stirred to the water surface hereinafter, so that lime-ash is taken out of outside submerged slag conveyor 3 by scraper plate.
Specifically, rabbling mechanism 2 includes impeller 21, what impeller 21 can rotate is set in taper slag notch, and leaf
The part-structure of wheel 21 is located at the water surface or less.It can specifically, being provided between two opposite inner walls of taper slag notch
The shaft of rotation, impeller 21 are set in shaft.Since the chain 32 of scraper slag removing machine 3 drives scraper plate movement to carry out scraping slag, because
The flowing of water in this shell 31 can be rotated with impeller 21, and the rotation of impeller 21 can be to the lime-ash in taper slag notch
It is stirred, coalescence after preventing more lime-ash from mixing with water is piled into hard " grey slag plate ", while will swim on the water surface
Lime-ash be stirred to the water surface or less and taken away by scraper plate, prevent lime-ash from blocking slag dropping tube 1, improve slagging-off efficiency.
In addition, rabbling mechanism 2 further includes rocking handle 22, rocking handle 22 is located at the outside of taper slag notch, and is connected to shaft, makes
Obtaining operator can be rotated by 22 impeller 21 of rocking handle.Since the flowing velocity of the water in scraper slag removing machine 3 has
Limit can accelerate the velocity of rotation of impeller 21 by rocking handle 22 when needing quickly slagging-off, to accelerate mixing speed, so that cone
Lime-ash in shape slag notch is quickly discharged.
Specifically, slag dropping tube 1 includes tubular body 11, tapered portion 12 and dilatation portion 13.Wherein, in the present embodiment,
Tubular body 11 is cylindrical structure, and one end is connected to dry bottom hopper 4, and the other end is connected to tapered portion 12, and tubular body 11 uses
Cylindrical structure is not present slag dead angle, can reduce lime-ash in the attachment of 11 inner wall of tubular body, but the present embodiment is to tubulose
The structure of ontology 11 is without being limited thereto, and tubular body 11 can also be prismatic structures.
Above-mentioned tapered portion 12 is the conical structure matched with tubular body 11, convenient for tapered portion 12 and tubular body 11
Be connected and fixed, when tubular body 11 be prismatic structures when, corresponding tapered portion 12 be pyramid-shaped structures.Tapered portion 12 it is small
Diameter end is connected to tubular body 11, and the bigger diameter end of tapered portion 12 is connected to dilatation portion 13, forms above-mentioned taper inside tapered portion 12
Slag notch, taper slag notch can increase the contact area of lime-ash and water, enable lime-ash and water Rapid contact and coalescence, with
It is discharged afterwards by the stirring of impeller 21 by scraper slag removing machine 3, lime-ash is avoided to block slag dropping tube 1.
At work, the part-structure in dilatation portion 13 extend into the water surface hereinafter, carrying out to slag dropping tube 1 close to the deslagging device
Envelope, in the present embodiment, the cross-sectional area in dilatation portion 13 are equal to the maximum cross-section area of tapered portion 12, can not only guarantee lime-ash
There is biggish contact area with water, and the amount of the open ended lime-ash of slag dropping tube 1 can be further increased, when heating boiler
Working strength increases, and when the grey quantity of slag of generation increases, dilatation portion 13 can temporarily store a certain amount of lime-ash, avoids the grey quantity of slag prominent
So increasing may cause the problem of slag dropping tube 1 blocks.
In addition, in the present embodiment, inspection hole 121 is offered in tapered portion 12, inspection can be opened or closed by being additionally provided with
Look into the door body in hole 121.The case where lime-ash inside taper slag notch can be observed by inspection hole 121, can if lime-ash accumulation is excessive
Accelerate the velocity of rotation of impeller 21 by rocking handle 22, to reinforce stirring action, so that lime-ash is quickly arranged by submerged slag conveyor 3
Out.In addition, can also be cleaned to the lime-ash adhered on impeller 21 by inspection hole 121, avoid 21 weight of impeller increase and
It can not be rotated under the drive of water flow, improve slagging-off speed.
In addition, remaining heat evaporates moisture in lime-ash when lime-ash drops on the water surface, vapor is fallen with subsequent
Lower lime-ash mixing is attached on the inner wall of slag dropping tube 1, it is also possible to and cause slag dropping tube 1 to block, it, can by being set to tapered portion 12
Greatly reduce the amount of the vapor entered in tubular body 11, to avoid adhering to more ash on the inner wall of tubular body 11
Slag, and the lime-ash being attached on 12 inner wall of tapered portion is mixed with vapor, other tools (such as scoop etc.) can be used and pass through
Above-mentioned 121 abate of inspection hole, so that slag dropping tube 1 be avoided to block.
Heating boiler provided in this embodiment can be improved slagging-off speed by using above-mentioned deslagging device, guarantee heating
Normal operation of boiler.
