Description
Technical Field
The utility model relates to the technical field of superheaters, in particular to a device for improving working conditions of a fin tube of a superheater.
Background
The fin tube designed according to the traditional superheater structure is extremely easy to cause bending damage of fins on the fin tube due to vibration of the fin tube and influence the heat exchange effect of the fin tube in production operation; the fin tube vibration is further increased along with bending damage of the fin, and the joint welding seam of the fin tube and the equipment shell is damaged and the safe operation of the equipment is affected.
Therefore, it is necessary to invent a device for improving the operation of the superheater finned tubes.
Disclosure of Invention
The utility model provides a device for improving the working condition of a fin tube of a superheater, which is characterized in that through holes are uniformly formed in a tube plate for installing the fin tube, the device also comprises a support plate welded on the inner side of the through holes of the tube plate, and the top of the support plate is arranged at the bottom of the fin tube so as to solve the problem that the fin on the fin tube is easily bent and damaged due to the vibration of the fin tube and influence the heat exchange effect of the fin tube; the fin tube vibration is further increased along with the bending damage of the fin, and the problem that the connecting welding seam between the fin tube and the equipment shell is damaged and the safe operation of the equipment is affected is further caused.
In order to achieve the above object, the present utility model provides the following technical solutions: the utility model provides an improve device of superheater finned tube operating mode, includes the tube sheet, evenly set up the through-hole installation finned tube on the tube sheet, still include the through-hole inboard welding at the tube sheet have the backup pad, the backup pad top sets up in the finned tube bottom.
Preferably, the width of the supporting plate is larger than the thickness of the supporting plate, the supporting plate is arc-shaped, and the circle center of the supporting plate is the same as the circle center of the finned tube.
The beneficial effects of the utility model are as follows: the structure is simple, the design is reasonable, the design can adapt to the characteristic of large vibration under the working condition of the fin tube of the vertical superheater, and the problems of large vibration, easiness in bending of the fin tube and poor heat exchange effect of the fin tube under the working condition of the conventional fin tube of the vertical superheater can be solved; meanwhile, the device has the characteristic of simple installation and disassembly.

Detailed Description
The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present utility model only, and are not intended to limit the present utility model.
Referring to fig. 1-6, the device for improving working conditions of the fin tube of the superheater provided by the utility model comprises a tube plate 1, wherein through holes are uniformly formed in the tube plate 1 for installing the fin tube 3, and the device further comprises a support plate 2 welded on the inner side of the through holes of the tube plate 1, the top of the support plate 2 is arranged at the bottom of the fin tube 3, the width of the support plate 2 is larger than the thickness of the support plate 2, the support plate 2 is arc-shaped, and the circle center of the support plate 2 is identical with the circle center of the fin tube 3;
the lower bottom surface of the support plate 2 is welded with the tube plate 1, the finned tube 3 is directly arranged on the support plate 2 and cannot be welded with the support plate 2 to ensure that the finned tube 3 is heated and freely expands in a telescopic manner under working conditions, the support area of the finned tube 3 is increased through the support plate 1 when the finned tube 3 is in working conditions, the stress condition of fins of the finned tube 1 is improved, the fins are prevented from being bent and damaged, and meanwhile, the installation precision of the support plate 1 and the tube plate 1 is improved, and the installation requirement of the finned tube 1 is met; when the superheater finned tube is in working condition, the vibration of the finned tube 3 is limited by the supporting plate 1, and meanwhile, the stress condition of the fins of the finned tube 1 is improved because the supporting area is increased, so that the fins of the finned tube 1 are prevented from being bent and damaged under the working condition;
the application process of the utility model is as follows: those skilled in the art uniformly set up the through-hole on tube sheet 1, weld backup pad 2 in the through-hole inboard of tube sheet 1, insert the fin tube 3 of superheater in the through-hole of tube sheet 1 again, fin tube 3 bottom contact backup pad 2 top.
The above description is of the preferred embodiments of the present utility model, and any person skilled in the art may modify the present utility model or make modifications to the present utility model with the technical solutions described above. Therefore, any simple modification or equivalent made according to the technical solution of the present utility model falls within the scope of the protection claimed by the present utility model.
