Description
Technical field
This utility model relates to water-tight equipment technical field, is specially a kind of soot blower positive seal device.
Background technology
In coal-burning boiler unit, commonly used steam sootblower is removed on boiler furnace, superheater, reheater and economizer
Dust stratification and slagging scorification, it is possible to be used for removing the dust stratification of furnace roof and tubular air preheater.During steam soot blowing, soot blower rifle
Manage whole stroke and pass boiler setting, abrasion or bite do not occur, between gun barrel and boiler setting for ensureing that gun barrel gives a present to passing in and out
There is certain gap.In boiler operatiopn, owing to being affected by working conditions change, burner hearth can produce pressure-fired, causes boiler to fly
Ash sprays from gun barrel gap location through walls, causes substantial amounts of flying dust to pollute environment.Additionally the reciprocating motion of soot blower gun barrel also can be taken
Band flying dust, causes soot blower gun barrel bite and other faults, increases plant maintenance workload.Simultaneously as soot blower gun barrel with
There is certain gap between boiler setting, this gap makes Air Leakage Into Boilers situation aggravate so that blower fan is exerted oneself increase, simultaneously because of
Boiler oxygen-excess combustion can cause coking, reduces boiler efficiency, in order to solve these problems, therefore, it is proposed that a kind of soot blowing
Device positive seal device.
Utility model content
The purpose of this utility model is to provide a kind of soot blower positive seal device, to solve to carry in above-mentioned background technology
The problem gone out.
For achieving the above object, this utility model following technical scheme of offer: a kind of soot blower positive seal device, including
Soot blower gun barrel body, malleation wall case, air delivery apparatus and sealing air pipe, described soot blower gun barrel body interior is cylindrical
Cavity structure, and soot blower gun barrel body both sides are provided with malleation wall case, are provided with air delivery apparatus, institute inside described malleation wall case
State air delivery apparatus to include annular seal space, seal pipe and sealing air pipe, inside described air delivery apparatus, be provided with annular seal space, described
Being provided with sealing pipe inside annular seal space, described sealing air pipe is internal with annular seal space to be connected.
Preferably, described air delivery apparatus uses cast steel structure cast alloy material to make, described air delivery apparatus
Sealing surface use line style seal structure.
Preferably, described sealing pipe uses high temperature resistant synthetic material.
Preferably, described soot blower gun barrel body uses floating type subdivision structure.
Compared with prior art, the beneficial effects of the utility model are: this steam sootblower positive seal device, use two
Level seal form, produces Tiny pore wall, thus is effectively prevented stove between its air delivery apparatus and soot blower gun barrel, burner hearth
The leakage of thorax flying dust, air delivery apparatus can rock with gun barrel reliably and slide simultaneously, seals the most effectively, overall structure letter
Single, easy to use, low cost.
Accompanying drawing explanation
Fig. 1 is this utility model one soot blower positive seal apparatus structure schematic diagram.
In figure: 1 soot blower gun barrel body, 2 malleation wall casees, 3 air delivery apparatus, 31 annular seal spaces, 32 sealing pipes, 4 sealings
Airduct.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, a kind of technical scheme of this utility model offer: a kind of soot blower positive seal device, including soot blowing
Device gun barrel body 1, malleation wall case 2, air delivery apparatus 3 and sealing air pipe 4, described soot blower gun barrel body 1 is internal is cylinder
Shape cavity structure, and soot blower gun barrel body 1 both sides are provided with malleation wall case 2, described malleation wall case 2 is internal is provided with air delivery dress
Putting 3, described air delivery apparatus 3 includes annular seal space 31, seals pipe 32 and sealing air pipe 4, and described air delivery apparatus 3 is internal to be set
Having annular seal space 31, the internal sealing pipe 32 that is provided with of described annular seal space 31, described sealing air pipe 4 is internal with annular seal space 31 to be connected.
This utility model improves and advantage is: this soot blower positive seal device, uses steel by air delivery apparatus 3
Structure cast alloy material is made, and sealing surface uses linear sealing to seal, so that air delivery apparatus 3 has slip merit
Can, and the least with soot blower gun barrel body 1 gap, the advantage with automatic capturing, both can ensure that sealing, it is also possible to subtract
Few soot blower gun barrel body wear amount, uses high temperature resistant synthetic material by sealing tube body 1, is effectively protected soot blower rifle
Tube body 1, thus avoid owing to the reciprocating motion of soot blower gun barrel body 1 causes gun barrel to wear and tear, the soot blower gun barrel brought
The economic loss that body 1 is changed, uses floating type subdivision structure by soot blower gun barrel body 1, has more thoroughly administered soot blower
Gun barrel body 1 seal box leak out ash problem.
This utility model, by using malleation to dredge gas collecting mode, makes full use of sealing air pipe 4 and sealing air is sent into sealing
In chamber 31, it is achieved sealing between soot blower gun barrel body and furnace body, soot blower gun barrel body 1 Seal Design is divided into two-stage close
Envelope: one-level is air current sealed for sealing, and there are gap between air delivery apparatus 3 and soot blower gun barrel body 1, and sealing air passes through
Air delivery apparatus 3 make to be formed between air delivery apparatus 3 with ash device gun barrel body 1 together with malleation air current sealed, thus effectively
Prevent burner hearth pressure-fired leakage spray ash；Two grades is employing 2 road annular seal spaces in air delivery apparatus, and the chamber of sealing air is main
Wanting sealing area, after this chamber is passed through sealing air, soot blower barrel closure wind does not leaks, and then prevents burner hearth hot blast to outside
Environment leaks, it is achieved that sealing purpose.Air delivery apparatus 3 can rock with soot blower gun barrel body and slide reliably, seals
The most effectively.
Embodiment the most of the present utility model, for the ordinary skill in the art,
It is appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, repair
Changing, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
