Description
Technical field
The present invention relates to a kind of sealing device, be specifically related to a kind of sealing device for heated surface at the end of boiler.
Background technology
Heated surface at the end of boiler utilizes working medium in the heat heating surface of high-temperature flue gas, thus reduces exhaust gas temperature, improves pot
Stove combined cycle efficiency, reaches the purpose of energy-conserving and environment-protective.Therefore the excellent sealing of heated surface at the end of boiler is when boiler operatiopn
Play vital effect.
The sealing majority of original structure Fig. 1: existing heated surface at the end of boiler uses shaped steel backplate form, and heating surface surrounding steel protects
Plate surrounds, and acts on boiler body framework, sees detail drawing 2.The form that heating surface uses support beam to coordinate with pipe clamp carries out solid
Fixed, see detail drawing 3.Support beam acts on the steel panel of both sides, offers support beam perforate on steel panel, and heated surface bundle is straight
Section part of horizontal passes before and after's steel panel, then seals with comb plate, comb joint.The most this structure needs in actual production process
Heating surface surrounding steel panel is all carried out perforate, higher to requirement on machining accuracy, otherwise can affect in-site installation.Additionally
The most also being uneconomic, the parts that the composition structure that this back-end surfaces seals needs mainly have: four
Face steel panel, support beam, pipe clamp, comb plate, comb joint, for supporting the framework of surrounding steel panel, steel consumption amount is big.Secondly,
This sealing structure is the most relatively cumbersome when overhauling in the future, need to be opened by front and back's both sides wallboard, finds out after need to overhauling a little again by front
Rear both sides wallboard restores.
Summary of the invention
The invention aims to solve existing boiler tail and seal that the processing capacity existed is big, precision prescribed is high, installation difficulty
Big and that maintenance amount is big problem.And then a kind of sealing device for heated surface at the end of boiler is provided.
The technical scheme is that a kind of sealing device for heated surface at the end of boiler include two horizontal seal backplates,
Support beam, two channel-section steels and multiple pipe clamp, support beam is vertically arranged, and two horizontal seal backplates are horizontally arranged at support beam
Upper and lower, is provided with a channel-section steel outside the end of each horizontal seal backplate, it also includes comb plate, comb joint, and comb plate, comb joint hangs down
Straight being fixed in support beam in support beam and at vertical direction, multiple pipe clamps are fixedly mounted on the most successively near boiler
On the comb plate, comb joint of afterbody heat exchanger tube side, and boiler tail heat exchanger tube may pass through comb plate, comb joint.
The present invention compared with prior art has the effect that
1, the heating surface support beam of the present invention directly serves as boiler tail framework, both ensure that the knot that former boiler heating surface is fixing
Configuration formula, effectively reduces again steel consumption cost.About 1/2nd of original structure steel panel weight.
2, both sides steel panel before and after the present invention cancels, thus exempt heated surface bundle perforate through walls, on the one hand reduce processing
Difficulty, on the one hand can save steel consumption.
3, both sides of the present invention steel panel directly acts in heating surface support beam, exempts in former boiler structure on the steel panel of both sides
Support beam perforate, packaging efficiency improves 30%, it is to avoid affect field erected problem due to machining accuracy.
4, comb plate, comb joint of the present invention welds with pipe clamp monolithic, without opening before and after both sides overall steel backplate during maintenance, and directly will comb
The dismounting of shape plate monolithic i.e. can be taken off overhauling tube panel and carries out maintenance replacing, the most convenient.

Detailed description of the invention
Detailed description of the invention one: combine Fig. 1 to Fig. 6 and illustrate that present embodiment, present embodiment include that two horizontal seal are protected
Plate 1,2, two channel-section steels 3 of support beam and multiple pipe clamp 4, support beam 2 is vertically arranged, two horizontal seal backplate 1 levels
Being arranged on the upper and lower of support beam 2, be provided with a channel-section steel 3 outside the end of each horizontal seal backplate 1, it also wraps
Including comb plate, comb joint 5, comb plate, comb joint 5 is perpendicular to support beam 2 and is fixed in support beam 2 at vertical direction, and multiple pipe clamps 4 are by upper
It is fixedly mounted on successively under on the comb plate, comb joint 5 of boiler tail heat exchanger tube side, and boiler tail heat exchanger tube may pass through comb
Shape plate 5.
Fixing for heating surface support beam as boiler tail framework, is coordinated installation by present embodiment with pipe clamp, reaches fixing and is subject to
The effect of hot side, cancels boiler tail framework in original structure.
The both sides of present embodiment are protected and are directly acted in heating surface support beam, can remove from both sides steel panel in original structure figure
Support beam perforate.
Present embodiment utilize comb plate, comb joint to replace in original structure figure before and after steel panel, directly carry out with pipe clamp and both sides steel panel
Seal weld, steel panel before and after can cancelling in original structure figure, thus exempt backplate perforate one procedure.
Present embodiment comb plate, comb joint monolithic makes, and with pipe clamp welded seal, during maintenance, tube bank can single screen dismounting in the future.
Detailed description of the invention two: combine Fig. 6 and present embodiment is described, the comb plate, comb joint 5 of present embodiment includes the first sheet material
5-1, tri-plate 5-3 and multiple second sheet material 5-2, multiple one or two/half is offered in the lower end of the first sheet material 5-1
Justifying pit 5-1-1, the top and bottom of the second sheet material 5-2 offer multiple 1st/2nd semicircle pit 5-1-2 respectively,
Multiple 1st/3rd semicircle pit 5-1-3, the first sheet material 5-1 and multiple second plate are offered in the upper end of tri-plate 5-3
Material 5-2 is from top to bottom fixedly connected sequentially, and the 1st/1st adjacent semicircle pit 5-1-1 and two or two/half
Circle pit 5-1-2 forms circular hole, the 1st/2nd semicircle pit 5-1-2 and the 1st/3rd semicircle pit after fastening
5-1-3 forms circular hole after fastening.Being arranged such, in cost angle analysis, steel consumption amount and factory, manufacture is former protecting
About 1/2nd of plate structure form, overhaul angle analysis from running in the future, and the tail sealing structure after remodeling, if individually
When changing tube panel, being taken off by the comb plate, comb joint that tube panel is connected and just can be taken off tube panel, changing tube panel before remodeling then needs to protect lateral symmetry
Tube panel is extracted out after taking off by plate entirety again, compares the sealing structure before remodeling, is substantially shorter inspection after tail sealing structure remodeling
Repair the time.Other composition is identical with detailed description of the invention one with annexation.
Detailed description of the invention three: combine Fig. 6 and present embodiment is described, the first sheet material 5-1 and multiple second of present embodiment
