Abstract
The utility model provides a kind of anti-slurries retention structure of power plant boiler discharge flue, and comprise flue, non-metal expansion joint and deflector, this flue is interconnected to constitute by the tube coupling that multiple diameter is identical; This non-metal expansion joint to be arranged between adjacent tube coupling and to connect adjacent tube coupling; This deflector to be arranged in flue and to be positioned at the bottom of the vertical direction of non-metal expansion joint inner surface, and the bottom of the area covering non-metal expansion joint of deflector after installing.Deflector of the present utility model can prevent from being entered in the U-shaped structure of non-metal expansion joint by the lime stone slurry flow through bottom non-metal expansion joint, and does not affect normal damping and the drawing effect of non-metal expansion joint.
Description
Technical field
The utility model relates to field of boilers, particularly relates to a kind of anti-slurries retention structure of power plant boiler discharge flue.
Background technology
In pipeline connects, often adopt non-metal expansion joint to be used as connecting the connector of adjacent channel, its material of non-metal expansion joint is mainly fabric, rubber, exotic material etc., the vibrations that energy air blower of compensating, airduct run and pipe deforming.In the flue gas desulphurization system of thermal power plant, the extrusome of non-metal expansion joint extensive use is covering, and being formed by the silicon rubber of function admirable or the MULTILAYER COMPOSITE such as high silica polytetrafluoroethylene (PTFE) and alkali-free glass silk floss, is a kind of high-strength sealing composite.It, while absorption swell increment, also can prevent the seepage of gas leakage and rainwater.
But in use, because non-metal expansion joint exists the buffer structure of a U-shaped, cause the lime stone slurry flowed out with flue gas can remain in non-metal expansion joint place, adds additional the bearing capacity of non-metal expansion joint, and after long-play, the slurries retained can produce certain corrosion to non-metal expansion joint, non-metal expansion joint can be made to pull and tear, thus reduce the service life of non-metal expansion joint under the vibrations that operational outfit produces.
Utility model content
An object of the present utility model is the anti-slurries retention structure that will provide a kind of power plant boiler discharge flue.To reach the performance neither affecting non-metal expansion joint in flue, the object of lime stone slurry can not be retained again in non-metal expansion joint.
Especially, the utility model provides a kind of anti-slurries retention structure of power plant boiler discharge flue, it is characterized in that comprising:
Flue, the tube coupling identical by multiple diameter is interconnected to constitute;
Non-metal expansion joint, to be arranged between adjacent described tube coupling and to connect adjacent described tube coupling;
Deflector, to be arranged in described flue and to be positioned at the bottom of the vertical direction of described non-metal expansion joint inner surface, and the bottom of non-metal expansion joint described in the area covering of described deflector after installing.
Further, described tube coupling is circular or oval, and described deflector is the arc corresponding with described tube coupling cross sectional shape and the center of circle overlaps with the center of circle of described non-metal expansion joint.
Further, described tube coupling is rectangular tube, and described deflector is the U-board corresponding with described tube coupling cross sectional shape.
Further, described deflector enters one end and described non-metal expansion joint or described tube coupling near flue gas and fixes, and to enter one end away from described flue gas be movable end.
Deflector of the present utility model can prevent from being entered in the U-shaped structure of non-metal expansion joint by the lime stone slurry flow through bottom non-metal expansion joint, and does not affect normal damping and the drawing effect of non-metal expansion joint.Deflector of the present utility model can adopt nonmetallic materials to make equally, to reach etch-proof object.
According to hereafter by reference to the accompanying drawings to the detailed description of the utility model specific embodiment, those skilled in the art will understand above-mentioned and other objects, advantage and feature of the present utility model more.
Accompanying drawing explanation
Hereinafter describe specific embodiments more of the present utility model with reference to the accompanying drawings by way of example, and not by way of limitation in detail.Reference numeral identical in accompanying drawing denotes same or similar parts or part.It should be appreciated by those skilled in the art that these accompanying drawings may not be drawn in proportion.In accompanying drawing:
Fig. 1 is the anti-slurries retention structure schematic diagram according to the utility model embodiment;
Fig. 2 is the deflector structure schematic diagram according to the utility model embodiment;
Fig. 3 is the deflector structure schematic diagram according to another embodiment of the utility model.
Detailed description of the invention
As shown in Figure 1, anti-slurries retention structure of the present utility model can comprise flue 10, non-metal expansion joint 20 and deflector 30 in general manner, and this flue 10 is for discharging the flue gas after vulcanizing treatment, and the tube coupling 11 identical by multiple diameter is interconnected to constitute.This non-metal expansion joint 20 to be arranged between adjacent tube coupling 11 and to connect adjacent tube coupling 11, to reduce or to slow down the vibrations between tube coupling 11.This deflector 30 is arranged on the inner surface of non-metal expansion joint 20 and is positioned at the bottom of the vertical direction of non-metal expansion joint 20, and the bottom of area covering non-metal expansion joint axial length of deflector 30 after installing, to accept by the lime stone slurry flow through in flue 10, make it can not contact with non-metal expansion joint 20, and then prevent lime stone slurry to be deposited in the U-shaped structure of non-metal expansion joint 20.
Deflector 30 in the utility model can adopt elastomeric material to make, to improve its corrosion resistant performance.Deflector 30 adopts to seal with the axial two ends of non-metal expansion joint 20 and contacts.Axial two ends bottom the axial two ends of deflector 30 and non-metal expansion joint 20 can be fixed in this embodiment, enter to prevent lime stone slurry, because deflector 30 adopts elastomeric material, the normal function of non-metal expansion joint 20 therefore can not be affected with non-metal expansion joint 20 deform in same pace.
In another embodiment, this deflector 30 can by enter one end and non-metal expansion joint 20 or tube coupling 11 is fixed near flue gas, and deflector 30 to enter one end away from flue gas be movable end, deflector 30 centre after fixing covers on non-metal expansion joint 20.When non-metal expansion joint 20 stretches, the deflector 30 that one end is fixed can keep covering state with the stretching of non-metal expansion joint 20, and lime stone slurry can not be made to enter the U-shaped structure of non-metal expansion joint 20.Concrete fixed form can adopt gluing or that screw is fixing mode.
Further, as shown in Figure 2, when the tube coupling 11 forming flue 10 is circular or oval, this deflector 30 can be the arc corresponding with tube coupling 11 cross sectional shape and the center of circle overlaps with the center of circle of non-metal expansion joint 20.As shown in Figure 3, when the tube coupling 11 forming flue 10 is rectangular tube, this deflector 30 is the U-board corresponding with tube coupling 11 cross sectional shape.By above-mentioned deflector 30 structure matched, the contact relation of itself and non-metal expansion joint 20 can be improved.
So far, those skilled in the art will recognize that, although multiple exemplary embodiment of the present utility model is illustrate and described herein detailed, but, when not departing from the utility model spirit and scope, still can directly determine or derive other modification many or amendment of meeting the utility model principle according to content disclosed in the utility model.Therefore, scope of the present utility model should be understood and regard as and cover all these other modification or amendments.
