Description

Boiler superheater tube panel fixes device

Technical field

The utility model relates to boiler power station technical fields, and in particular to a kind of fixed device of boiler superheater tube panel.

Background technique

Superheater is an important component of boiler, mainly passes through the acting for increasing vapor (steam) temperature to increase steam Ability, to improve power plant's thermodynamic efficiency.

Superheater in the prior art is normally fixed unreasonable, the superheater because of caused by superheater tube stagger arrangement frequent occurrence Tube panel deformation and the problem for hanging coke.Again because superheater is in the higher region of fire box temperature, under high-temperature flue gas disturbance, overheat It can be shaken back and forth between pipe row in device and pipe row, Guan Yuguan, wear tube wall, finally being thinned with tube wall, is easy to produce quick-fried Pipe phenomenon.In addition, pipe clamp in the prior art is usually combed plate pipe clamp, the contact between the pipe clamp and superheater tube connects for line Touching, causes superheater tube that concentrated wear can still occur between pipe clamp in the case where weak vibrations, is also easy to gall tube wall, drop The security performance of low equipment, and repair not only construct it is relatively difficult but also costly.

Problem above is urgently to be resolved.

Utility model content

In view of the deficiency of background technique, the technical problem to be solved by the utility model is to provide can consolidate clamping overheat It device pipe and communicating pipe prevents from it from damaging in long-term use and effectively improves the high boiler superheater tube panel of its service life fixing Device.

To realize the above-mentioned technical purpose, the utility model provides following technical solution:

Boiler superheater tube panel fixes device, including several superheater tubes arranged in parallel, it is characterised in that the mistake It is equipped with a communicating pipe perpendicular with it by hot device pipe, are fixed by pipe clamp the superheater tube and the communicating pipe, The pipe clamp includes a pair of intermediate plate for being symmetrical arranged and mutually fastening, and each intermediate plate has several first arc surfaces and one The outer wall of second arc surface, the corresponding superheater tube of each first arc surface fits, second circular arc Face and the outer wall of the communicating pipe fit.

The superheater tube is alternatively arranged in a criss-cross fashion with the communicating pipe.

The corresponding axle center of first arc surface axle center corresponding with second arc surface is perpendicular.

The outer wall of the intermediate plate has arc surface corresponding with first arc surface and the second arc surface.

The intermediate plate is an integral molding structure.

Two intermediate plates form buckling parts in the side of the communicating pipe, positioned at superheater tube two sides described in same root Gap between two intermediate plates is 2mm.

The pipe clamp is fixedly connected with the superheater tube by positioning round steel.

The utility model has the beneficial effects that more heater tubes of clamping and company normal thereto can be consolidated by pipe clamp Siphunculus, and effectively increase the contact area of heater tube, both communicating pipes between pipe clamp, thus mitigate heater tube be connected to The wear phenomenon occurred in long-term use is managed, is prolonged its service life；Simultaneously, moreover it is possible to effectively prevent because of heater tube, connection There is a phenomenon where the deformation of superheater tube screen caused by stagger arrangement and extension are burnt between pipe；In addition, by being reserved between a pair of of intermediate plate Gap can make intermediate plate be preferably bonded superheater tube, improve the clamping effect to superheater tube and communicating pipe.For existing skill The problems in art, the utility model provide

Specific embodiment

As shown in Figs. 1-5, the fixed device of boiler superheater tube panel, it is described including several superheater tubes 1 arranged in parallel A communicating pipe 2 perpendicular with it is equipped with by superheater tube 1, the effect of communicating pipe 2 is to turn on atmosphere, to prevent from producing in boiler Raw a large amount of steam are overstock in inside, influence security performance.In the present embodiment, the superheater tube 1 and the communicating pipe 2 with The mode of right-angled intersection is alternatively arranged, and the outermost in one group of superheater tube 1 can be set in communicating pipe 2, and setting can also be assigned to exist Between several superheater tubes 2.The superheater tube 1 and the communicating pipe 2 are fixed by pipe clamp, and the pipe clamp includes a pair The intermediate plate 4 for being symmetrical arranged and mutually fastening, each intermediate plate 4 have several first arc surfaces 41 and second arc surface 42, the corresponding axle center of first arc surface 41 axle center corresponding with second arc surface 42 is perpendicular.Each described first The outer wall of the corresponding superheater tube 1 of arc surface 41 fits, and second arc surface 42 is outer with the communicating pipe 2 Wall fits, in this way, realize the face contact between intermediate plate 4 and superheater tube 1, communicating pipe 2, increases contact area, The abrasion for effectively mitigating superheater tube 1, generating in the long-term use communicating pipe 2 prevents it because abrasion ruptures, thus The effectively security performance of enhancing equipment.Meanwhile passing through the position of pipe clamp fixed heater pipe 1 and communicating pipe 2, moreover it is possible to effectively prevent Superheater tube screen deformation and extension are burnt because caused by between heater tube 1, communicating pipe 2 there is a phenomenon where stagger arrangement.

The intermediate plate 4 is an integral molding structure, and each intermediate plate 4 so can be improved using whole precision-investment casting The intensity of intermediate plate 4 guarantees that a pair of of intermediate plate 4 can consolidate and clamps superheater tube 1 and communicating pipe 2.The outer wall of the intermediate plate 4 have with First arc surface 41 and the corresponding arc surface of the second arc surface 42.

Two intermediate plates 4 form buckling parts in the side of the communicating pipe 2, and carry out make-up interlocking by buckling parts, A pair of of intermediate plate 4 is enabled securely to clamp superheater tube 1 and communicating pipe 2 therebetween.Positioned at 1 two sides of superheater tube described in same root Two intermediate plates 4 between gap be 2mm.By the preset clearance between a pair of of intermediate plate 4, intermediate plate 4 can be made preferably It is bonded superheater tube 1, improves the clamping effect to superheater tube 1 and communicating pipe 2.

The pipe clamp is fixedly connected with the superheater tube 1 by positioning round steel 3, further consolidates the position of superheater tube 1 It sets, prevents it from positional shift and stagger arrangement occurring in long-term use, to improve the security performance of equipment.
