Abstract
The invention discloses a kind of boiler superheater tube panel fixed structure, including some groups of pipe clamps, every superheater tube matches somebody with somebody unification group pipe clamp, every group of pipe clamp includes two intermediate plates, the inwall of intermediate plate is in cabochon, and fitted with the outer peripheral face of superheater tube wall, connect and be integrally formed from beginning to end between the adjacent clips of the same side, and it is respectively provided with screw in junction, bolt is set in screw, the intermediate plate for being located at superheater tube both sides respectively is connected so as to which superheater be clamped by bolt attaching nut, and pipe clamp, bolt and nut are made of exotic material.Above-mentioned setting allows formation face between superheater pipe clamp and superheater tube to contact, and superheater tube folder fixed form can at least be alleviated or avoid and concentrated wear be occurred between clamp road, and prevents stagger arrangement and cause superheater tube screen to deform and hang burnt.
Description
Technical field
The present invention relates to boiler power station technical field, and in particular to a kind of boiler superheater tube panel fixed structure.
Background technology
Superheater is as the important component in boiler, and it mainly does function by increasing vapor (steam) temperature with increase steam
Power, so as to improve power plant's thermodynamic efficiency.
Superheater of the prior art is unreasonable due to fixation, often occurs superheater tube stagger arrangement and causes superheater tube screen
Deformation and extension are burnt.Pipe clamp come off cause superheater tube screen outside smoke-shock and steam inside impact in the presence of and and pipe clamp
Occur to rock relatively, so as to cause tube panel to wear and tear.
It is combed plate pipe clamp to design in the prior art most, and the contact between the pipe clamp and superheater tube is linear contact lay, is led
Cause pipeline still can occur partial contact rubbing between pipe clamp in the case of weak vibrations and finishing superheater pipeline is occurred part
Abrasion, its concentrated wear depth can be normally reached 2mm, and superheater pipeline wall thickness is relatively thin in itself, so the mistake after being worn
Hot device pipeline may result in the leakage of boiler finishing superheater.
The content of the invention
The technical problem to be solved in the present invention is to solve above-mentioned the deficiencies in the prior art to reduce superheater tube mill there is provided one kind
The boiler superheater tube panel fixed structure of damage.
In order to solve above-mentioned the deficiencies in the prior art, the technical solution adopted by the present invention is：A kind of boiler superheater tube panel
Fixed structure, including some groups of pipe clamps, every superheater tube match somebody with somebody unification group pipe clamp, and every group of pipe clamp includes two intermediate plates, intermediate plate
Inwall is in cabochon, and is fitted with the outer peripheral face of superheater tube wall, the connection and one from beginning to end between the adjacent clips of the same side
It is body formed, and be respectively provided with junction in screw, screw bolt is set, bolt attaching nut will be located at superheater tube two respectively
The intermediate plate of side is connected to clamp in superheater, and pipe clamp, bolt and nut are made of exotic material.
Further, the outer wall of the intermediate plate also be in cabochon, and with inwall and superheater tube it is concentric set.
Further, what the bolt and intermediate plate were linked to be direct-connected is vertically arranged.
Further, the pipe clamp is made using Integral melting molding.
Further, it is provided with respectively between the intermediate plate end of same superheater tube both sides between 1.5~2.5mm
Gap.
From above-mentioned technical proposal it can be seen that the present invention has advantages below：Above-mentioned setting allow superheater pipe clamp with
Face contact is formed between superheater tube, superheater tube folder fixed form can at least be alleviated or avoid and be sent out between clamp road
Raw concentrated wear, and prevent stagger arrangement and cause superheater tube screen to deform and hang burnt；Preset clearance is set, bolt can be facilitated
Regulation, and bending can be facilitated in the intermediate plate of cabochon, so that superheater tube of preferably fitting, by superheater pipe clamp
Tightly.
Brief description of the drawings
Fig. 1 is the present invention and superheater tube scheme of installation front view；
Fig. 2 is the present invention and superheater tube scheme of installation top view；
Fig. 3 is structural representation of the invention.
Embodiment
The embodiment of the present invention is elaborated below in conjunction with accompanying drawing.
As shown in Fig. 1,2 or 3, boiler superheater tube panel fixed structure of the invention, including some groups of pipe clamps, every mistake
Hot device pipe matches somebody with somebody unification group pipe clamp, and every group of pipe clamp includes two intermediate plates 1, and the inwall of intermediate plate is in cabochon, and with the wall of superheater tube 2
Outer peripheral face is fitted, and is connected and is integrally formed from beginning to end between the adjacent clips of the same side, hot investment casting, material are touched using Integral melting
Matter uses high temperature resistant 2520, and is respectively provided with setting bolt 4 in screw 3, screw 3 in junction, and the attaching nut of bolt 4 will respectively
Intermediate plate positioned at the pipe both sides of superheater 2 is connected to clamp in superheater, and bolt 4 and nut 5 use heat-resistance stainless steel
Material.
Above-mentioned setting allows formation face between superheater pipe clamp and superheater tube to contact, the clamping fixed side of the superheater tube
Formula can at least be alleviated or avoid and concentrated wear be occurred between clamp road, and prevents stagger arrangement and cause superheater tube screen
Deformation and extension are burnt.
The outer wall of the intermediate plate also be in cabochon, and with inwall and superheater tube it is concentric set.Bolt and intermediate plate
What is be linked to be direct-connected is vertically arranged.The pipe clamp moulds the intermediate plate end made and be located at same superheater tube both sides respectively using Integral melting
1.5~2.5mm gap is provided between portion.Preset clearance is set, the regulation of bolt can be facilitated, and can in the intermediate plate of cabochon
To facilitate bending, so that superheater tube of preferably fitting, superheater tube is clamped.
The typical method of embodiments of the present invention is described in detail above in association with accompanying drawing, still, the present invention is not limited to
Detail in above-mentioned embodiment, in the range of the technology design of the present invention, can be carried out to technical scheme
A variety of simple variants, these simple variants belong to protection scope of the present invention.
