Description

Technical Field

[0001] This invention relates to the field of heat dissipation and noise reduction technology for high-temperature pipelines, and more specifically to a vibration reduction, ventilation and noise reduction system for high-temperature pipelines. Background Technology

[0002] In industrial production, pipelines typically suffer from the "three highs" problem: high temperature, high pressure, and high noise. Currently, existing technologies for addressing these issues cannot simultaneously solve both heat dissipation and noise reduction. For pipelines with strict heat dissipation requirements, there are currently no effective noise reduction measures. These pipelines often have noise levels exceeding 115 dB(A), exhibiting broadband characteristics, which seriously affects the physical and mental health of employees and the normal lives of surrounding residents. For pipelines without strict temperature requirements, they can be divided into two categories: First, when the pipeline temperature does not exceed 400℃, a noise reduction structure combining ultrafine centrifugal glass wool and color-coated steel plates can generally be used. Second, when the pipeline temperature exceeds 400℃, a noise reduction structure combining aluminum silicate wool and color-coated steel plates can generally be used. In both types of noise reduction structures, ultrafine centrifugal glass wool or aluminum silicate wool primarily function as sound absorbers, while color-coated steel plates primarily function as sound insulators. Therefore, these two noise reduction structures only reduce noise and cannot achieve heat dissipation.

[0003] Furthermore, in high-temperature, high-pressure, and high-noise pipelines, the flow of the medium inside causes surge problems. In normal-temperature pipelines, dampers are usually attached to the outer wall to address surge and achieve vibration reduction. Although the dampers are made of flame-retardant materials, they are not non-combustible and therefore cannot be used in high-temperature pipelines. The lack of high-temperature resistant vibration damping devices severely limits the noise reduction effect of these high-temperature, high-pressure, and high-noise pipelines.

[0004] In conclusion, how to simultaneously achieve heat dissipation and noise reduction for pipelines subjected to high temperature, high pressure, and high noise has become a pressing technical problem that needs to be solved. Summary of the Invention

[0012] Preferably, the central heat dissipation and noise reduction module includes a detachable heat dissipation and noise reduction module located at the weld of the original pipeline. The detachable heat dissipation and noise reduction module is configured to be directly detached from the heat dissipation and noise reduction device and to be directly installed into the heat dissipation and noise reduction device.

[0013] Preferably, the first heat dissipation and noise reduction module includes a first sound-absorbing ventilation cavity that serves as part of the ventilation and heat dissipation channel for airflow passage, and first sound-absorbing components for noise reduction respectively disposed on both sides of the first sound-absorbing ventilation cavity.

The middle heat dissipation and noise reduction module includes a middle sound-absorbing ventilation cavity that serves as part of the ventilation and heat dissipation channel for airflow passage, and a middle sound-absorbing component for noise reduction disposed on the side of the middle sound-absorbing ventilation cavity away from the original duct.

Furthermore, a sound-absorbing component is installed on the side of the ventilation and heat dissipation channel away from the original pipeline. This component absorbs and reduces the noise generated by the pipeline; moreover, because the sound-absorbing component is positioned away from the original pipeline relative to the ventilation and heat dissipation channel, it avoids the problem of poor heat dissipation caused by direct contact between the sound-absorbing component and the original pipeline.

[0029] It should also be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0030] All terms used in this invention have the same meaning as understood by one of ordinary skill in the art to which this invention pertains, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.

[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0032] This invention addresses the problem of simultaneously achieving noise reduction and heat dissipation in high-temperature, high-pressure, and high-noise pipelines, providing a vibration reduction, ventilation, and noise reduction system for high-temperature pipelines. (Refer to...) Figure 1 The vibration reduction and ventilation noise reduction system includes: a heat dissipation and noise reduction device, which can be configured to be wrapped around the outer wall of the original pipe 7. The heat dissipation and noise reduction device has a ventilation and heat dissipation channel 6 and a sound-absorbing component located on the side of the ventilation and heat dissipation channel 6 away from the original pipe 7. The ventilation and heat dissipation channel 6 can reduce the temperature of the original pipe 7 through gas flow, and the sound-absorbing component can reduce the noise of the original pipe 7.

[0033] Through the above technical solution, the vibration reduction, ventilation, and noise reduction system for high-temperature pipelines provided by this invention encloses a heat dissipation and noise reduction device on the outer wall of the original pipeline. This device includes a ventilation and heat dissipation channel and a sound-absorbing component. Air can be introduced into the ventilation and heat dissipation channel, and the airflow carries away the heat from the pipeline, thereby achieving heat dissipation. Furthermore, a sound-absorbing component is installed on the side of the ventilation and heat dissipation channel away from the original pipeline. This component absorbs and reduces the noise generated by the pipeline. Simultaneously, because the sound-absorbing component is positioned away from the original pipeline relative to the ventilation and heat dissipation channel, the problem of reduced heat dissipation effect due to direct contact between the sound-absorbing component and the original pipeline is avoided.

[0034] In some optional embodiments of the present invention, the sound-absorbing component may include a sound-absorbing bag and a metal sound-insulating plate, and the sound-absorbing bag and the metal sound-insulating plate work together to achieve the effect of reducing noise.

[0035] Preferably, the sound-absorbing assembly may include a perforated metal sound-absorbing plate, a sound-absorbing package, and a metal sound-insulating plate arranged sequentially along a direction away from the ventilation and heat dissipation channel 6. The perforated metal sound-absorbing plate has multiple holes to allow noise to pass through; the sound-absorbing package absorbs at least partially the noise passing through the holes; and the metal sound-insulating plate isolates the noise passing through the sound-absorbing package. The perforated metal sound-absorbing plate can also support the sound-absorbing package and the metal sound-insulating plate, ensuring the overall structure of the heat dissipation and noise reduction device is stable.

[0036] Preferably, the perforation rate of the metal perforated sound-absorbing panel is not less than 25%, so that noise entering the ventilation and heat dissipation channel 6 can enter the sound-absorbing component and achieve the purpose of noise reduction through the absorption effect of the sound-absorbing package and the sound insulation effect of the metal sound insulation panel.

[0037] In addition, the sound-absorbing component also includes a hydrophobic glass cloth disposed on the side of the sound-absorbing package near the metal perforated sound-absorbing plate. The hydrophobic glass cloth can protect the sound-absorbing package. For example, the hydrophobic glass cloth can prevent water vapor in the ventilation and heat dissipation channel 6 from being absorbed by the sound-absorbing package, thereby reducing the sound absorption effect of the sound-absorbing package.

[0038] Preferably, the vibration reduction, ventilation and noise reduction system for high-temperature pipelines provided by the present invention further includes a metal vibration damping strip disposed on the side of the heat dissipation and noise reduction device close to the original pipeline 7. The metal vibration damping strip can reduce the vibration of the original pipeline 7 and is also resistant to high temperature, making it suitable for high-temperature pipelines.

[0039] Additionally, refer to Figures 1-5 The heat dissipation and noise reduction device may include a first heat dissipation and noise reduction module 1 and a middle heat dissipation and noise reduction module. There are two first heat dissipation and noise reduction modules 1, which are respectively located at both ends of the original pipe 7. The middle heat dissipation and noise reduction module is located between the two first heat dissipation and noise reduction modules 1 to enclose the original pipe 7. The heat dissipation and noise reduction device is formed by assembling multiple first heat dissipation and noise reduction modules 1 and middle heat dissipation and noise reduction modules, which makes the heat dissipation and noise reduction device easier to disassemble, install, and maintain.

[0040] Of course, both ends of the first heat dissipation and noise reduction module 1 can be planes, and both ends of the middle heat dissipation and noise reduction module can also be planes.

Alternatively, preferably, refer to Figure 1 and Figure 2 One end of the first heat dissipation and noise reduction module 1 has a stepped surface, and the end of the middle heat dissipation and noise reduction module connected to one end of the first heat dissipation and noise reduction module 1 has a corresponding stepped surface. The first heat dissipation and noise reduction module 1 and the middle heat dissipation and noise reduction module are connected by a stepped surface connection, thereby enhancing the stability and sealing of the connection between the first heat dissipation and noise reduction module 1 and the middle heat dissipation and noise reduction module, and improving the heat dissipation and noise reduction effect of the heat dissipation and noise reduction device.

[0061] Preferably, refer to Figure 1 The widths of the first sound-absorbing ventilation cavity 1-7 and the middle sound-absorbing ventilation cavity are equal to allow for stable airflow within the ventilation and heat dissipation channel 6. Specifically, the middle sound-absorbing ventilation cavity includes a second sound-absorbing ventilation cavity 2-7, a third sound-absorbing ventilation cavity 3-7, and a fourth sound-absorbing ventilation cavity 4-7. Therefore, the widths of the first sound-absorbing ventilation cavity 1-7, the second sound-absorbing ventilation cavity 2-7, the third sound-absorbing ventilation cavity 3-7, and the fourth sound-absorbing ventilation cavity 4-7 are equal, preferably 50-100 mm.

[0062] Preferably, refer to Figures 1-5The first sound-absorbing ventilation cavity 1-7 and the middle sound-absorbing ventilation cavity extend along the original duct 7, and are provided with axial ventilation openings that allow gas to flow through the first sound-absorbing ventilation cavity 1-7 and the middle sound-absorbing ventilation cavity. Specifically, along the extension direction of the original duct 7, the first metal bending member 1-4-1, the third metal bending member 1-5, the third metal bending member 2-4, the fourth metal bending member 2-5, the fifth metal bending member 3-4, the sixth metal bending member 3-5, the seventh metal bending member 4-4, and the eighth metal bending member 4-5 are respectively provided with the following ventilation openings: the first ventilation opening 1-4-1, the third ventilation opening 1-5-2, the fifth ventilation opening 2-4-2, the sixth ventilation opening 2-5-1, the seventh ventilation opening 3-4-1, the ninth ventilation opening 3-5-2, the tenth ventilation opening 4-4-1, and the eleventh ventilation opening 4-5-1, so as to allow air to flow smoothly into and out of the ventilation and heat dissipation channel 6, thereby achieving heat dissipation and cooling of the original duct 7.

[0063] Preferably, refer to Figures 1-4 At the connection between the first sound-absorbing ventilation cavity 1-7 and the middle sound-absorbing ventilation cavity, a radial ventilation opening is provided along the direction perpendicular to the extension of the original pipe 7. Specifically, along the direction perpendicular to the extension of the original pipe 7, a second ventilation opening 1-5-1, a fourth ventilation opening 2-4-1, and an eighth ventilation opening 3-5-1 are respectively provided on the second metal bending member 1-5, the third metal bending member 2-4, and the sixth metal bending member 3-5. When only axial ventilation openings are provided, the airflow channel in the ventilation and heat dissipation channel 6 near the connection between the first sound-absorbing ventilation cavity 1-7 and the middle sound-absorbing ventilation cavity will be narrowed, causing the airflow near the connection to be disturbed. Therefore, by providing a radial ventilation opening at the connection between the first sound-absorbing ventilation cavity 1-7 and the middle sound-absorbing ventilation cavity, the airflow in the ventilation and heat dissipation channel 6 can be kept at a constant speed. The airflow velocity in the ventilation and heat dissipation channel 6 is preferably 5-10 m / s.

[0064] It should be noted that no sound-absorbing components are installed on the side of the central sound-absorbing ventilation cavity closest to the original duct 7. This allows the heat carried by the original duct 7 to directly enter the central sound-absorbing ventilation cavity, maximizing its heat dissipation effect. The first heat dissipation and noise reduction modules 1, located at both ends of the original duct 7, have first sound-absorbing components installed on both sides of their first sound-absorbing ventilation cavities 1-7, preventing a large amount of noise from being discharged through the beginning and end of the ventilation and heat dissipation channel 6. Therefore, by installing first sound-absorbing components on both sides of the first sound-absorbing ventilation cavities 1-7, and only installing the central sound-absorbing component on the side of the central sound-absorbing ventilation cavity furthest from the original duct 7, heat dissipation and noise reduction are balanced to the greatest extent possible.

[0065] In addition, in this invention, the metal sound insulation board, the metal perforated sound absorption board, the metal bending parts and the metal vibration damping belt are all made of metal materials, which have the characteristics of high temperature resistance, enabling the heat dissipation and noise reduction device to operate stably in high temperature environment and extending the service life of the heat dissipation and noise reduction device.

[0066] Preferably, the heat dissipation and noise reduction device further includes sound-insulating sealing strips 5 respectively disposed at the connection gaps between the first heat dissipation and noise reduction module 1 and the middle heat dissipation and noise reduction module. Specifically, sound-insulating sealing strips 5 are provided at the connection gaps between the first heat dissipation and noise reduction module 1, the second heat dissipation and noise reduction module 2, the third heat dissipation and noise reduction module 3, and the detachable heat dissipation and noise reduction module 4, thereby further improving the sealing performance of the heat dissipation and noise reduction device and ultimately improving the heat dissipation and noise reduction performance of the vibration reduction and ventilation noise reduction system of the present invention. The sound-insulating sealing strips can be made of EPDM sealing tape, and the preferred specifications (width × thickness) are 30 × 3 mm.

[0067] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the inventive concept, various simple modifications can be made to the technical solutions of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
