[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] like Figure 1 As shown, this application embodiment provides a wall-penetrating pipe anti-abrasion device, including a protective plate 100 and a filling layer 400; a plurality of protective plates 100 are arranged to form a protective groove, which is used to cover the wall-penetrating pipe 200, and the filling layer 400 is disposed in the protective groove to fill the gap between the protective groove and the wall-penetrating pipe 200.

[0028] That is, the present invention provides that by forming an anti-slip groove on the outside of the through-wall pipe 200 by the protective plate 100 and sealing it with a filling layer 400, the through-wall pipe 200 is protected, which solves the technical problem in the prior art that the through-wall pipe 200 exposed to the complex flue gas dynamics environment of the boiler room is susceptible to coupled damage from sulfuric acid dew point corrosion and ash particle erosion and wear, thus ensuring the long-term operation of the equipment.

[0029] Specifically, the protective plate 100 can be a rectangular plate made of plastic or wood, which is spliced ​​together using bolts, wires, and other connectors to form a protective groove. The protective groove is rectangular in shape and covers the outside of the through-wall pipe 200. The filling layer 400 is placed inside the protective groove and can be made of wear-resistant and fire-resistant plastic to fill the gap between the protective groove and the through-wall pipe 200, wrapping the through-wall pipe 200 and protecting it.

[0030] Furthermore, the anti-abrasion device for through-wall pipes also includes supporting steel bars 300; several supporting steel bars 300 are set in the protective groove, the supporting steel bars 300 are used to connect with the wall, and the protective plate 100 is connected to the supporting steel bars 300.

[0031] Specifically, one end of the supporting steel bar 300 is welded to the wall near the through-wall pipe 200, thereby fixing it to the wall. In this embodiment, multiple supporting steel bars 300 are provided, some of which are connected to the top wall near the through-wall pipe 200, and others are connected to the side wall near the through-wall pipe 200, thus forming a mesh-like square frame. The protective plate 100 is fixed to the supporting steel bar 300 by bolts or wires. Thus, the strength of the through-wall pipe anti-corrosion device can be improved by using the supporting steel bar 300.

[0032] Furthermore, the anti-abrasion device for through-wall pipes also includes a support mesh; the support mesh is installed inside the protective groove and is connected to the support steel bars 300.

[0033] Specifically, in this embodiment, the support mesh is set as a wire mesh, which is placed between the gaps of the support reinforcing bars 300 and connected to the support reinforcing bars 300, thereby further improving the strength of the through-wall pipe anti-corrosion device.

[0034] Furthermore, the filling layer 400 is made of wear-resistant, fire-resistant, and plastic.

[0035] Specifically, the filling layer 400 is made of wear-resistant and fire-resistant plastic, an amorphous refractory material composed of 70%–80% granular and powdered materials, 10%–25% plastic clay and other binders, and an appropriate amount of plasticizer. It is inexpensive and easy to construct and install.

[0036] Furthermore, the anti-abrasion device for the through-wall pipe also includes a protective tile; the protective tile is installed over the through-wall pipe 200.

[0037] Specifically, the protective tile is shaped like the pipe, wrapping around the through-wall pipe 200 and installed inside the filling layer 400. The protective tile can be made of 316L stainless steel, thereby improving the protection of the through-wall pipe 200.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
