Description
Technical field
The present invention relates to thermal power generating technology field, more particularly to a kind of boiler hot First air pipeline elevator arrangement.
Background technology
In thermal power plant, heat primary air pipeline is the pipeline for providing coal dust drying medium and combustion air, heat primary air
Pipeline uniform force, piping have very important effect safely to safe operation of power plant.In conventional art, export in air preheater
It is all to be connected using non-metal compensator at heat primary air pipe joint, for compensating the displacement of air preheater interface, but compensator
Setting can increase the blind flange force of pipeline, the suspension and support above compensator is arranged and is difficult to shadow of the blind flange force to compensator is completely eliminated
Ring, the compensator for interface occur is drawn bad phenomenon, when serious, affect the safe operation of unit.
Content of the invention
Based on this, for the problems referred to above, the present invention proposes a kind of boiler hot First air pipeline elevator arrangement, can eliminate
Blind flange force at air preheater heat primary air pipe joint, can share interface stress and solve compensator herein and be drawn bad wind
Danger.
Its technical scheme is as follows：
A kind of boiler hot First air pipeline elevator arrangement, including heat primary air pipeline and bracing frame；The heat is once
Wind pipeline includes air preheater heat primary air interface, channel bend section, pipeline vertical section and the pipe outlet for being sequentially connected setting；Institute
State channel bend section and flexible suspension is provided with, and the pipeline vertical section is provided with Three-D compensator and combination suspension bracket, described
Flexible suspension and combination suspension bracket are all connected to support frame as described above.
Air preheater heat primary air interface eliminates compensator, by having an area of section air preheater heat primary air interface transitions to circle
Shape heat primary air pipe section, and the channel bend section in the heat primary air pipeline is provided with flexible suspension, also in channel bend
Rigidity and spring assembly suspension bracket are provided with pipeline vertical section after section, between the combination suspension bracket, are provided with Three-D compensator absorption
The axially and radially displacement of heat primary air pipeline.
When heat primary air pipeline is in cold conditions, the setting of Three-D compensator will not produce blind flange force, now combine suspension bracket
Bear self weight of pipeline and combination suspension bracket make a concerted effort；When heat primary air pipeline is in hot, due to the setting of Three-D compensator,
Blind flange force upwards is produced at channel bend section, and now combination suspension bracket can be used to balance this blind flange force, make piping stress balance, separately
The deadweight of heat primary air pipeline can also be shared by outer spring suspension bracket, and combination suspension bracket lower support limits top on buckstay
Pipeline vertical section displacement expands downwards, and blind flange force is caused entirely by spring hanger and combination suspension bracket by suspension bracket absorption is combined
Piping uniform force, and blind flange force effect is eliminated, while without the need for arranging compensator, pipeline in air preheater heat primary air interface
Blind flange force upwards is also eliminated at elbow section, is thoroughly solved interface compensator and is drawn bad risk, improve heat once
The security of wind pipeline, so as to improve the security reliability of unit operation.
Below its further technical scheme is illustrated：
Further, the pipeline exit is additionally provided with fixed mount, and the fixed mount is connected to support frame as described above.Pass through
Fixed mount is provided with the bottom of pipeline vertical section, can the expansion of restriction conduit and piping further direction of displacement.
Further, the channel bend section includes pipeline the first elbow section being sequentially connected and pipeline the second elbow section,
And the first flexible suspension is provided with the pipeline the first elbow section, the second bullet is provided with the pipeline the second elbow section
Property suspension bracket.Multiple flexible suspensions are correspondingly arranged according to channel bend section elbow structure feature, make piping stress more balanced.
Further, first flexible suspension and the second flexible suspension all include to be set to U-shaped and be sheathed on pipeline
Suspension bracket base, and be respectively symmetrically the spring hanger portion for being connected to the suspension bracket base two ends, the spring hanger portion connection
In support frame as described above.Arrange U-shaped suspension bracket base to be easy to flexible suspension is sheathed on pipeline, symmetrically arranged spring hanger portion makes
Stress evenly supports more stable reliability.
Further, the pipeline vertical section both sides are respectively symmetrically and are provided with a combination suspension bracket, and described in two
Combination suspension bracket is enclosed on the outside of the Three-D compensator.In the same manner, pipeline vertical section both sides are symmetricly set in two combination suspension brackets,
Pipeline stress is made evenly to support more stable.
Further, each described combination suspension bracket includes to be arranged at the rigid support portion on the pipeline vertical section top, institute
State that rigid support portion one end is connected to the pipeline vertical section and the other end is connected to support frame as described above；Also include to be arranged at described
The elastic support portion of the vertical pars infrasegmentalis of pipeline, elastic support portion two ends are all connected to the pipeline vertical section.In heat once
Wind pipeline in cold conditions when, making a concerted effort for self weight of pipeline and elastic support portion is born in the rigid support portion for combining suspension bracket, now elasticity
Cradle portion is in compressive state；When heat primary air pipeline is in hot, due to the setting of Three-D compensator, at channel bend section
Blind flange force upwards is produced, now the rigid support portion failure in combination suspension bracket, elastic support portion stress downwards, balances this blind
Plate power, makes piping stress balance.
Further, described elastic support portion and the rigid support portion of each combination suspension bracket all staggers setting,
And two springy support parts are not symmetricly set on the outside of the Three-D compensator.By elastic support portion and rigid support portion
Stagger setting, so that the two stress point on pipeline is in staggered distribution, it is to avoid the stress at pipeline one is excessive, force balance effect is also more
Good.
Further, the elastic support portion is mutually staggered 90 ° with the rigid support portion and arranges.Two of combination suspension bracket
Misclassification opens 90 ° of settings, makes pipeline and itself stress reach optimum state.
The present invention has following prominent：The form of rigid hanger and spring hanger combination is employed, without the need in sky
Pre- device heat primary air interface arranges compensator, eliminates the blind flange force arranged produced by compensator so that the stress of interface is divided
Carry on a shoulder pole and thoroughly can solve compensator herein and bad risk is drawn, improve unit operation security.
