Abstract
The utility model relates to an air equalizing and dust removing device for a boiler with a reciprocating grate. An air delivery pipe is arranged on the side surface of a machine body and is communicated with air chambers through air inlet cylinders. The bottom of each air chamber forms an inclining shape along an air inlet direction. One end of each air chamber near to each air inlet cylinder is a lower end. An ash removing auger is arranged along the inclining bottom of the air chamber. The cross sections of the air chambers are gradually changed from large to small along the flow direction of airflows. The air pressure of the air chambers is even. The volume (particularly the height) of the boiler is greatly reduced.
Description
The utility model relates to a kind of equal wind, ash handling equipment of boiler, is specially adapted to the reciprocating-grate boiler of one-sided air-supply.
The reciprocating-grate boiler combustion process has blockiness, during burning, the middle part is different with the air capacity that two ends need, thereby generally all adopt zoned air, it is the independent air compartment that is divided into several mutual isolation under the fire grate, each air compartment can be regulated air quantity on demand, has solved the problem of vertical reasonable wind distribution.But still exist the inhomogeneities of width along fire grate (promptly horizontal) air-supply, also can cause on the grate burning inhomogeneous.Particularly during single admission, owing to after the air-flow of the fair speed that enters from a side enters air compartment, cause the fire grate cross air dispatching inhomogeneous because of axial flow velocity reduces gradually.Boiler combustion efficiency is had a significant impact.For addressing this problem, the 70-71 page or leaf of " miniature boiler design and repacking " (second edition) book that science tech publishing house (1989) publishes has proposed a solution.Promptly in that " wind scoop formula air compartment is arranged below the reciprocal grate, and air enters wind scoop formula air compartment through air register, and air register is along the fire grate lateral arrangement, and air can be very even along the horizontal distribution of fire grate like this." air channel, system storehouse of " cross section is very big " need be set below air compartment in this scheme, the volume (particularly height) of boiler is increased.Complicated integral structure makes troubles also for the air compartment ash disposal.
The utility model is the improvement to prior art, its objective is to reciprocating-grate boiler provides a kind of reasonable wind distribution, and is simple in structure, can obviously reduce boiler height and ash disposal all wind, ash handling equipment easily.
The equal wind of reciprocating-grate boiler described in the utility model, ash handling equipment adopt following technical scheme to realize.
The equal wind of reciprocating-grate boiler described in the utility model, ash handling equipment comprise ajutage, air intake tube, body, ash disposal auger and remove ash pipe, and the regulating gate of air intake tube, it is characterized in that:
A, ajutage are communicated with each air compartment by the air intake tube in the side of body.
The bottom of B, each air compartment is skewed along the air intake direction, and an end of nearly air intake tube is a low side.
C, ash disposal auger are installed along the tilting bottom of air compartment.
The equal wind of aforesaid reciprocating-grate boiler, ash handling equipment, when boiler operatiopn, air blast is sent wind to each air intake tube by ajutage and is sent into each air compartment again.Enter the coal seam by each air compartment again through the fire grate slit to the fire grate bottom at last and participate in burning.In above-mentioned equal wind, ash handling equipment, each air compartment is low skewed of nearly air intake tube end along the cross section of air intake direction, the sectional area of whole air compartment gradually changes along the air current flow direction is descending, make that the air compartment blast is even, realized the laterally even air distribution of fire grate, the air-supply of fire grate vertical partition then can be regulated on demand by the regulating gate of air funnel.So structure has reached the purpose of reasonable wind distribution.
In addition, the ash disposal auger is installed along the air compartment tilting bottom, has guaranteed the air compartment space effectively, and the ash that falls falls into the tube of ash disposal auger from the top of auger, guided to outside the air compartment by auger again.At last the dust stratification unification is removed.Reached effective.The purpose of ash disposal easily.
The equal wind of above-mentioned reciprocating-grate boiler, ash handling equipment are owing to the varied cross section of utilizing auger and air compartment to form realizes equal wind, do not need heavy in section isobaric air channel, and air blast and ajutage greatly reduce boiler volume (particularly height) all in the side of equal wind apparatus, and structure obtains simplifying.
As mentioned above, the utility model has reached its intended purposes.
Below in conjunction with embodiment the utility model is further described.
Fig. 1～Fig. 3 is the utility model embodiment schematic diagram.
Fig. 1 is a vertical view, and Fig. 2 is that A-A analyses and observe promptly along the fire grate longitdinal cross-section diagram, and Fig. 3 is that the B-B cutaway view is promptly along the fire grate cross-sectional view.
Among the figure: (1) is ajutage, and (2) are the air intake tubes, and (3) are bodies, and (4) are air compartments, and (5) are the ash disposal augers, and (6) are reciprocal grates, and (7) are the regulating gates of air intake tube (2), and this regulating gate is in order to solve vertically the problem of air distribution on demand.
Aforesaid body (3) can be whole product, then installs easily, and can be the part of boiler foundation also, during installation relevant parts are assembled up, then can more effectively reduce boiler height.
Claims (1)
1, a kind of equal wind, ash handling equipment of reciprocating-grate boiler comprise it is characterized in that the regulating gate (7) of ajutage (1), air intake tube (2), body (3), ash disposal auger (5) and air intake tube (2):
A, ajutage (1) are communicated with each air compartment (4) by air intake tube (2) in the side of body (3),
The bottom of B, each air compartment (4) is skewed along the air intake direction, and an end of nearly air intake tube (2) is a low side,
C, ash disposal auger (5) are installed along the tilting bottom of air compartment (4).
