Description

Technical Field

[0001] This utility model relates to the field of expansion joint technology, specifically to a desulfurization-specific fluororubber integrated vulcanized skin. Background Technology

[0002] In various circulating fluidized bed boilers, gas turbine waste heat boilers, and industries such as chemical, power generation, cement, papermaking, and high-rise buildings, deformation occurs between equipment, between equipment and pipelines, and between pipelines due to thermal expansion and contraction. Corrosion-resistant non-metallic compensators, i.e., non-metallic expansion joints, are usually used to compensate for displacement, absorb vibration, and reduce noise. They are mainly made of high-temperature resistant materials such as fiber fabrics and rubber to compensate for the vibration of fans and ducts and the deformation of pipelines.

[0003] Existing non-metallic expansion joints are made of silicone rubber and fiberglass cloth. They have poor resistance to strong corrosion from chemicals such as sulfides, cyanides, acids, alkalis, and nitrates in the flue gas and dust emitted from the above systems. They are easily damaged, have poor sealing performance, poor structural strength, are easy to break, and have poor temperature resistance, resulting in a short service life and a low removal rate of harmful substances, which can lead to environmental pollution. Utility Model Content

[0004] In response to the shortcomings of existing technologies, the purpose of this utility model is to provide a desulfurization-specific fluororubber integrated vulcanized skin, which has a simple and reliable structure and features high strength, corrosion resistance, and high temperature resistance.

[0005] The technical solution adopted by this utility model is: a desulfurization-specific fluororubber integrated vulcanized skin, including a composite skin and skin plates located at both ends of the composite skin; both skin plates are provided with a composite part on the side near the composite skin, and the composite part is provided with a number of spaced composite holes, so that the composite part has a hollow structure; the composite skin includes a number of fluororubber layers, and an aramid fabric layer is provided between two adjacent fluororubber layers; the fluororubber layers at both ends of the composite skin are pressed onto the front and rear surfaces of the composite part.

[0006] In this technical solution, the two ends of the composite structure are pressed onto the composite part of the skin plate. The composite structure is made of multiple layers of fluororubber, and there is also an aramid cloth layer between adjacent fluororubber layers. The composite structure of each layer significantly improves the structural strength, corrosion resistance and high temperature resistance of the expansion joint, and its service life is longer.

[0007] Preferably, the composite holes in the upper and lower rows of the composite part are arranged in an alternating pattern.

[0008] Preferably, the outermost fluororubber layer of the composite skin is coated with a fire-retardant paint layer.

[0009] Preferably, the composite skin undergoes overall vulcanization treatment.

[0010] Preferably, the skin panel is a 2205 stainless steel plate layer.

[0011] The beneficial effects of this utility model are as follows: The composite skin in this utility model adopts a multi-layer structure, and the skin plate is fixed to the composite skin by pressing through the composite part. The hollow structure of the composite part ensures the firmness of the entire structure after the composite. The composite structure of each layer significantly improves the structural strength, corrosion resistance and high temperature resistance of the expansion joint, and its service life is longer. It can be widely used in desulfurization equipment in industries such as power, chemical, and metallurgy, promotes the reliability upgrade of environmental protection equipment, has significant economic and social benefits, and has high practical value.

[0016] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0017] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0018] like Figure 1 and Figure 2As shown in the figure, a specific embodiment of this utility model provides a desulfurization-specific fluororubber integrated vulcanized skin, including a composite skin 200 and skin plates 100 located at both ends of the composite skin 200; both skin plates 100 are provided with a composite part 110 on the side near the composite skin 200, and the composite part 110 is provided with a plurality of spaced composite holes 111, so that the composite part 110 has a hollow structure; the composite skin 200 includes a plurality of fluororubber layers 210, and an aramid fabric layer 220 is provided between two adjacent fluororubber layers 210; the fluororubber layers 210 at both ends of the composite skin 200 are pressed onto the front and rear surfaces of the composite part 110.

[0019] like Figure 1 and Figure 2 As shown, through the above configuration, in this embodiment, the end of the skin plate 100 near the composite skin 200 is pressed together with the multi-layer composite skin 200 via the composite part 110. The composite skin 200 uses multiple layers of fluororubber, and there is also an aramid cloth layer 220 between adjacent fluororubber layers 210. The composite structure of each layer significantly improves the structural strength, corrosion resistance, and high-temperature capability of the expansion joint, resulting in a longer service life. The composite skin 200 uses multiple layers of fluororubber 210 pressed together. The molecular structure of fluororubber material is stable and can resist the erosion of strong corrosive media such as sulfur dioxide (SO2), hydrogen sulfide (H2S), and chloride ions (Cl-) in the desulfurization environment. Its acid and alkali corrosion resistance is significantly improved compared with traditional rubber skin. The aramid cloth layer 220 sandwiched between adjacent fluororubber layers 210 significantly improves the overall tear resistance of the skin and inhibits the creep deformation of the fluororubber layer 210 under high pressure conditions.

[0020] like Figure 1 and Figure 2 As shown, in order to ensure the stability of the composite connection between the skin panel 100 and the composite skin 200, the composite part 110 is provided with a number of spaced composite holes 111, so that the composite part 110 has a hollow structure. The composite holes 111 reduce the overall weight of the skin panel 100 while maintaining mechanical strength through the hole structure. At the same time, they ensure the contact area after the skin structure is pressed together, improve the structural strength after composite, and prevent the composite skin 200 from falling off from the skin panel 100.

[0021] like Figure 1 and Figure 2 As shown, the outermost fluororubber layer 210200 of the composite skin 200 is coated with a fire-retardant paint layer. The fire-retardant paint (such as an organosilicon flame-retardant coating) applied to the outermost fluororubber layer 210200 of the composite skin 200 can delay the spread of combustion and reduce the risk of fire in the desulfurization system in the event of accidental open flame contact. It also reduces dust adhesion in the flue gas, facilitating regular cleaning and maintenance.

[0022] like Figure 1 and Figure 2As shown, the composite skin 200 undergoes integral vulcanization treatment. Through this treatment, the fluororubber layer 210 and the aramid fabric layer 220 form chemical bonds, avoiding the delamination risk of traditional composite processes and ensuring structural stability under flue gas scouring and equipment vibration. In practical applications, the skin plate 100 is made of 2205 stainless steel. While providing rigid support, the skin plate 100, together with the fluororubber skin, forms a "rigid-flexible" system, adapting to thermal expansion and contraction during equipment start-up and shutdown.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model 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. 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 utility model, and they should all be covered within the scope of the claims and specification of this utility model.
