Description

Technical Field

[0001] The utility model relates to an integrated anti-corrosion corrugated pipe. Background Art

[0002] At present, the suspension beams of the tube bundles of boiler equipment (superheater, evaporator and economizer) are designed as hollow structures to prevent overheating and extension of service life of the beam body, so as to facilitate ventilation and cooling. The sealing structure at the penetration of the suspension beam through the wall is particularly important, which not only needs to ensure complete sealing (especially for positive pressure flue gas), but also needs to consider thermal expansion. At present, a corrugated pipe structure is generally adopted. However, since the ordinary corrugated pipe has no heat insulation layer, the high-temperature corrosive flue gas condenses into corrosive liquid in the corrugated pipe, resulting in corrosion and perforation of the corrugated pipe and flue gas leakage. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the defects of the prior art and provide an integrated anti-corrosion corrugated pipe, which is provided with an external heat insulation layer, and the corrugated pipe is in a hot wall state, so that the flue gas is not easy to condense, and the service life of the corrugated pipe is greatly improved.

[0004] The technical scheme for realizing the above purpose is: an integrated anti-corrosion corrugated pipe, which comprises a corrugated pipe body and two end connecting pipes. The two ends of the inner wall of the corrugated pipe body are connected to the two end connecting pipes in a one-to-one correspondence manner. An insulation layer integrally formed with the corrugated pipe body is arranged outside the corrugated pipe body, and a protective layer is arranged outside the insulation layer.

[0005] For the above integrated anti-corrosion corrugated pipe, one end connecting pipe is welded to the furnace wall plate, and the other end connecting pipe is welded to the suspension beam.

[0006] The integrated anti-corrosion corrugated pipe of the utility model is provided with an external heat insulation layer, and the corrugated pipe is in a hot wall state, so that the flue gas is not easy to condense, and the service life of the corrugated pipe is greatly improved. Description of the Drawings

[0007] Figure 1 It is a schematic structural diagram of the integrated anti-corrosion corrugated pipe of the utility model. Detailed Embodiment

[0008] In order to enable those skilled in the art in this technical field to better understand the technical scheme of the utility model, the following describes its detailed embodiment with reference to the drawings:

[0009] Please refer to Figure 1 , the best embodiment of the utility model, an integrated anti-corrosion corrugated pipe, which comprises a corrugated pipe body 2 and two end connecting pipes 1. The two ends of the inner wall of the corrugated pipe body 2 are connected to the two end connecting pipes 1 in a one-to-one correspondence manner. An insulation layer 3 integrally formed with the corrugated pipe body 2 is arranged outside the corrugated pipe body 2, and a protective layer 4 is arranged outside the insulation layer 3.

[0010] The integral anti-corrosion bellows of the present utility model is applicable to the sealing between the wall-piercing part of the support and suspension beam in the boiler equipment and the furnace wall plate. During use, one of the end connecting pipes 1 is welded to the furnace wall plate, and the other end connecting pipe 1 is welded to the support and suspension beam. It is simple and easy to construct, and convenient for maintenance and replacement. Since the heat insulation layer 3 integrally formed with the bellows body 2 is arranged outside the bellows body, the bellows body is in a hot wall state, and the flue gas is not easily condensed, greatly improving the service life of the bellows.

[0011] For the integral anti-corrosion bellows of the present utility model, the size of the bellows can be customized according to the size of the support and suspension beam.

[0012] In summary, for the integral anti-corrosion bellows of the present utility model, an external heat insulation layer is added, the bellows is in a hot wall state, and the flue gas is not easily condensed, greatly improving the service life of the bellows.

[0013] Those of ordinary skill in the art in this technical field should recognize that the above embodiments are only used to illustrate the present utility model and are not used to limit the present utility model. As long as within the scope of the substantial spirit of the present utility model, the changes and modifications to the above-described embodiments will fall within the scope of the claims of the present utility model.
