Description

Technical Field

[0001] This invention relates to the field of exhaust gas pipelines, and more particularly to a fiberglass pipe for collecting exhaust gas with flame-retardant and anti-static properties. Background Technology

[0002] The design and management of pipelines for the collection and transportation of organic waste gas are crucial to ensuring the safe and efficient operation of waste gas treatment systems. The design of pipelines for the collection and transportation of organic waste gas requires a focus on material selection, that is, selecting corrosion-resistant and high-temperature-resistant materials based on the characteristics of the waste gas, such as stainless steel or special plastics. However, during the transportation of organic waste gas, static electricity is easily generated by friction, so anti-static design and optimization of the pipelines are also necessary.

[0003] For example, CN202420570492.7 proposes an antistatic fiberglass pipe, which includes a base layer, a corrosion-resistant layer, a heat insulation layer, and a UV-resistant layer. Conductive fiber layers are bonded to both the inner and outer sides of the base layer, and conductive wires are filled within the base layer. These conductive wires are connected to the conductive fibers on both sides. Several conductive connectors are disposed on the outer side of the conductive fiber layers. The corrosion-resistant layer is located outside the conductive fibers and covers the portion of each conductive connector that contacts the conductive fibers. This antistatic fiberglass pipe, through the cooperation of conductive fibers and conductive connectors, conducts the charge on the inner wall of the pipe to the outside, preventing charge accumulation on the inner wall and potential accidents. It also utilizes the chemical corrosion resistance of the conductive fiber layer to reduce corrosion of the inner wall of the pipe and the frequency of replacement. However, the method of connecting the base layer with conductive wires is difficult and does not completely solve the aforementioned problems.

[0004] The present invention can discharge static electricity through the conductive layer, thereby reducing the static electricity generated during the transportation of organic waste gas. Summary of the Invention

[0005] Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a fiberglass pipe for collecting waste gas with flame-retardant and anti-static properties, solving the problem of static electricity generation during the transportation of organic waste gas.

[0006] Technical solution To achieve the above objectives, the present invention is implemented through the following technical solution: a fiberglass pipe for collecting waste gas with flame retardant and antistatic functions, comprising a pipe body, wherein the pipe body comprises an outer pipe layer, a conductive layer and an inner pipe layer, the conductive layer covering the surface of the inner pipe layer, and the outer pipe layer covering the outer surface of the conductive layer.

[0007] Furthermore, the outer tube layer can be made of resin of different types and specifications.

[0008] Furthermore, the conductive layer can be made of conductive copper wire or conductive tungsten wire, and there are two conductive wires used in the conductive layer. The conductive copper wire or conductive tungsten wire on both sides is connected to the pipe body joint or fitting interface and connected to the external grounding point of the pipe. The inner pipe layer is connected to the external grounding point through conductive copper wire or conductive tungsten wire.

[0009] Furthermore, the inner tube layer is a graphite layer tube structure mixed with resin.

[0010] Furthermore, an isolation layer is provided between the outer tube layer and the conductive layer.

[0011] Furthermore, the insulating layer is a tubular structure woven from glass fibers.

[0012] Furthermore, the outer tube layer is provided with support wires, which are fiber ropes, and at least one support wire is spirally arranged in the outer tube layer.

[0013] Furthermore, the support wire is a metal wire, and at least two support wires are arranged in parallel in the outer tube layer, located on both sides of the outer tube layer.

[0014] Furthermore, the tube body is corrugated, but the interior of the inner tube layer is straight.

[0015] Beneficial effects The present invention has the following beneficial effects: (1) The inner tube layer is a graphite layer tube structure mixed with resin, which allows the graphite to be stably fixed in the innermost part of the entire tube body, thus avoiding corrosion. It also allows the graphite to conduct electricity, which facilitates the elimination of static electricity generated during the transportation of waste gas.

[0016] (2) By setting up pipe body docking or pipe fitting docking interface, the conductive copper wire or conductive tungsten wire on both sides is connected and connected to the external grounding point of the pipeline. The inner pipe layer is connected to the external grounding point through conductive copper wire or conductor tungsten wire, thus achieving the effect of ensuring the safety of pipeline transportation.

[0017] (3) By using resins of different types and specifications as the outer tube layer, the configuration can be adapted to different types of waste gas to be transported, thus avoiding the risk of corrosion of the outer tube layer.

[0018] (4) The insulating layer is made of a tubular structure woven from glass fiber, which makes the insulating layer and the resin of the outer tube layer fit tightly together. Due to the electrical insulation of the glass fiber, the influence of external static electricity on the transport of exhaust gas is isolated, and the glass fiber and the conductive layer form a layered structure, so that the outer tube layer can be better separated during the grounding process of the conductive layer, which facilitates the grounding operation.

[0019] (5) By providing support wires in the outer tube layer, the toughness and strength of the outer tube layer are improved, while giving the outer tube layer the plasticity to bend.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1 - Figure 5 The present invention provides a technical solution comprising a tube body 1, wherein the tube body 1 comprises an outer tube layer 103, a conductive layer 102 and an inner tube layer 103, the conductive layer 102 covering the surface of the inner tube layer 103, and the outer tube layer 103 covering the outer surface of the conductive layer 102.

[0025] In this invention, the outer tube layer 103 can be made of resin of different types and specifications; More specifically, by using resins of different types and specifications, the configuration can be adapted to the different types of waste gas being transported in the application, thus avoiding the risk of corrosion of the outer pipe layer 103.

[0026] In this invention, the metal wire used in the conductive layer 102 can be a conductive copper wire or a conductive tungsten wire, and the number of metal wires used in the conductive layer 102 is two. The conductive copper wires or conductive tungsten wires on both sides are connected to the pipe body 1 at the butt joint or pipe fitting interface and connected to the external grounding point of the pipe. The inner pipe layer 103 is connected to the external grounding point through the conductive copper wire or the conductive tungsten wire. More specifically, by setting up a pipe body 1 docking or fitting docking interface to connect the conductive copper wires or conductive tungsten wires on both sides and connecting them to the external grounding point of the pipeline, and by setting up an inner pipe layer 103 to connect to the external grounding point through conductive copper wires or conductive tungsten wires, the effect of ensuring the safety of pipeline transportation is achieved.

[0027] In this invention, the inner tube layer 103 is a graphite layer tube structure mixed with resin; More specifically, by setting the inner tube layer 103 to a graphite layer tube structure mixed with resin, the graphite can be stably fixed on the outermost part of the entire tube body 1, which can prevent corrosion and also give full play to the conductivity of graphite, making it easy to eliminate static electricity generated during the transportation of exhaust gas.

[0028] like Figure 2 As shown, in this invention, an isolation layer 104 is provided between the outer tube layer 103 and the conductive layer 102; More specifically, the isolation layer 104 is a tubular structure woven from glass fiber. Due to the uneven texture produced by the weaving, the isolation layer 104 is tightly bonded to the resin of the outer tube layer 103. Due to the electrical insulation of the glass fiber, it isolates the influence of external static electricity on the exhaust gas transport and forms a layered structure between the glass fiber and the conductive layer 102. This allows for better separation of the outer tube layer 103 during the grounding process of the conductive layer 102, facilitating the grounding operation.

[0029] In this invention, the outer tube layer 103 is provided with support wires 2; More specifically, the support wire 2 is a fiber rope or a metal wire.

[0030] When the support wire 2 is a fiber rope, such as Figure 2 As shown, at least one support wire 2 is spirally arranged in the outer tube layer 103 to improve the toughness and strength of the outer tube layer 103; When the support wire 2 is a metal wire, such as Figure 3 As shown, at least two support wires 2 are arranged in parallel in the outer tube layer 103, located on both sides of the outer tube layer 103, which improves the toughness and strength of the outer tube layer 103 while giving the outer tube layer 103 bendable plasticity.

[0031] like Figure 4 As shown, in this invention, the tube body 1 is corrugated, and the outer tube layer 103, conductive layer 102, inner tube layer 103, isolation layer 104 and support wire 2 are corrugated accordingly. The two ends of the tube body 1 are flat openings for easy connection. More specifically, the corrugated structure of the tube body 1 improves its flexibility.

[0032] Better, such as Figure 5 As shown, the tube body 1 is corrugated, but the interior of the inner tube layer 103 is straight. More specifically, the corrugated structure of the tube body 1 improves the flexibility of the tube body 1, while the straight tube shape inside the inner tube layer 103 makes the internal exhaust gas transport smoother and reduces the static electricity generated by exhaust gas collision and friction.

[0033] In summary, this flame-retardant and anti-static high-concentration organic waste gas collection fiberglass pipe, by setting the inner pipe layer 103 as a graphite layer pipe structure mixed with resin, allows the graphite to be stably fixed inside the entire pipe body 1, preventing corrosion and also utilizing the conductivity of graphite to facilitate the elimination of static electricity generated during waste gas transportation. By setting the pipe body 1 to connect the conductive copper wires or conductive tungsten wires on both sides to the external grounding point, and by setting the inner pipe layer 103 to be connected to the external grounding point through conductive copper wires or conductive tungsten wires, the safety of pipeline transportation is ensured. By using different types and specifications of resin as the outer pipe layer 103, the configuration can be adapted to the different types of waste gas being transported, avoiding the risk of corrosion of the outer pipe layer 103. This solves the problems mentioned in the background technology.
