Description

Technical Field

[0001] This utility model relates to the field of natural gas compressors, specifically to a natural gas compressor with good noise reduction effect. Background Technology

[0002] Natural gas compressors are core equipment in the natural gas industry, mainly used to increase gas pressure for efficient storage, transportation, or processing. Natural gas compressors compress the volume of natural gas through mechanical work, increasing its pressure and temperature significantly.

[0003] A search revealed CN215762148U, a gas compressor designed for easy installation. The compressor comprises a base with multiple detachable support seats at its top. Each support seat has a slot on its upper surface. Bearings are located on the upper and lower inner walls of the support seats. A round rod is attached to the inner ring of the upper and lower bearings. One end of a pull rope is wound around the outer wall of the round rod, with the other end extending out of the support seat. A support plate is inserted into the support seat. A spring is located on the outer wall of the support plate, with a spring seat at the other end. An insert block is located on the outer side of the spring seat, with its outer end extending into the slot. The compressor body is located above the base. This device effectively facilitates quick installation and disassembly of the gas compressor, making operation simpler and more convenient, better meeting practical usage needs.

[0004] Existing natural gas compressors, due to a lack of effective noise reduction, emit a certain amount of noise during operation. This noise pollution leads to complaints from nearby residents and limits their overall use. Furthermore, the natural gas compressors in the aforementioned comparative case also lack effective noise reduction capabilities. Over time, the transmission of noise will increase the probability of damage to internal components of the natural gas compressor, thereby affecting its service life.

[0005] Therefore, it is necessary to invent a natural gas compressor with good noise reduction to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a natural gas compressor with good noise reduction effect. Through the synergistic effect of a multi-stage noise reduction structure, including a first noise reduction cover, a second noise reduction cover, a noise reduction plate, sound-absorbing glass wool, micro-perforations, sound-absorbing panels, sound-absorbing cotton strips, and a high-temperature resistant sound insulation sleeve, it can significantly absorb and reduce the noise emitted by the natural gas compressor body during operation. Moreover, the overall noise is controllable, making it suitable for noise-sensitive areas such as hospitals and residential areas, thus broadening the application range of natural gas compressor bodies. At the same time, the good noise reduction effect of the natural gas compressor also reduces the probability of damage to internal components due to noise transmission, thereby extending the overall service life of the natural gas compressor. This addresses the problem in existing technologies where the lack of good noise reduction during the operation of natural gas compressors leads to a certain amount of noise, causing pollution and complaints from surrounding residents, thus limiting the overall application range. Furthermore, the natural gas compressors in the aforementioned comparative cases also lack good noise reduction capabilities, and with long-term use, the transmission of noise increases the probability of damage to internal components, thereby affecting the service life of the natural gas compressor.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a natural gas compressor with good noise reduction effect, including a body support for placing the natural gas compressor;

[0008] A natural gas compressor body is fixedly installed above a body support for compressing natural gas. An exhaust pipe is fixedly installed above the natural gas compressor body. A first noise reduction cover is fitted on the outside of the natural gas compressor body. A double-ended bolt passes through the external thread of the first noise reduction cover. The other end of the double-ended bolt is threaded to a second noise reduction cover.

[0009] An inner frame is fixedly installed on both sides inside the first noise reduction cover and the second noise reduction cover. It is used to connect and install the noise reduction plate. Sound-absorbing glass wool is fixedly installed inside the noise reduction plate. Micro-perforations are opened on the outside of the noise reduction plate.

[0010] The sound-absorbing panel is set on the back of the noise reduction plate for secondary noise reduction. The sound-absorbing panel is fixedly installed with sound-absorbing cotton strips on the outside, and the exhaust pipe is covered with a high-temperature sound insulation sleeve. The inside of the high-temperature sound insulation sleeve is covered with a sound-absorbing coating.

[0011] Preferably, the first noise reduction cover and the second noise reduction cover are threadedly connected, and the inner frame is symmetrically arranged with respect to the central axis of the second noise reduction cover.

[0012] Preferably, the number of micro-perforations is set to multiple, and the multiple micro-perforations are distributed at equal intervals on the reduction plate.

[0013] Preferably, the high-temperature resistant sound insulation sleeve and the sound-absorbing coating are tightly bonded together, and the material of the sound-absorbing coating is aluminum oxide.

[0014] Preferably, the external thread of the first noise reduction cover is through a fastening bolt, and the front end of the fastening bolt is threaded to a heat sink bracket, and heat sink fins are fixedly installed inside the heat sink bracket.

[0015] Preferably, the number of heat dissipation fins is set to multiple, and the multiple heat dissipation fins are distributed at equal intervals on the heat dissipation frame.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] This utility model includes a first noise reduction cover, a second noise reduction cover, noise reduction plates, sound-absorbing glass wool, micro-perforations, sound-absorbing panels, sound-absorbing cotton strips, and a high-temperature resistant sound insulation sleeve. When using this natural gas compressor, because the compressor body is covered by the first and second noise reduction covers, when the compressor body emits noise, the noise reduction plates on both sides first reduce the high frequency of the noise through multiple micro-perforations on the outside. Then, the sound-absorbing glass wool inside the noise reduction plates further reduces the noise. The noise reduced by the noise reduction plates is then transmitted to the sound-absorbing panels, where it is absorbed by multiple wave-designed sound-absorbing cotton strips through a gradual change in acoustic resistance. Furthermore, the exhaust pipe outside the natural gas compressor body is also fitted with a high-temperature resistant sound insulation sleeve, which can further reduce noise transmission, thereby enabling the natural gas compressor to achieve a good noise reduction effect. With this combination, the multi-stage noise reduction structure works together to significantly absorb and reduce the noise generated by the operation of the natural gas compressor body. Moreover, the overall noise is controllable, making it suitable for noise-sensitive areas such as hospitals and residential areas, thus broadening the application range of the natural gas compressor body. At the same time, the natural gas compressor with a good noise reduction effect also reduces the probability of damage to internal components due to noise transmission, thereby extending the overall service life of the natural gas compressor.

[0018] This utility model is equipped with a first noise reduction cover, a second noise reduction cover, fastening bolts, a heat dissipation frame, and heat dissipation fins. When using this natural gas compressor, since the first and second noise reduction covers are fitted on the outside of the natural gas compressor body for noise reduction, heat dissipation frames and heat dissipation fins can be installed on the first and second noise reduction covers. In this way, multiple heat dissipation fins can assist in the rapid dissipation of the internal temperature of the natural gas compressor body and the inside of the first and second noise reduction covers, thereby ensuring the normal operation of the natural gas compressor. In this way, the heat dissipation fins can also have a sound-absorbing function through the arrangement of multiple heat dissipation fins, and enhance the noise reduction effect on the outside of the first and second noise reduction covers.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5 The natural gas compressor shown has good noise reduction effect, including a body support 1 for placing the natural gas compressor;

[0029] The natural gas compressor body 2 is fixedly installed above the body support 1 for natural gas compression, and an exhaust pipe 3 is fixedly installed above the natural gas compressor body 2. A first noise reduction cover 4 is fitted on the outside of the natural gas compressor body 2. A double-ended bolt 5 passes through the external thread of the first noise reduction cover 4, and a second noise reduction cover 6 is threaded to the other end of the double-ended bolt 5.

[0030] The inner frame 7 is fixedly installed on both sides inside the first noise reduction cover 4 and the second noise reduction cover 6. It is used to connect and install the noise reduction plate 8. The noise reduction plate 8 is fixedly installed with sound-absorbing glass wool 9 inside. The exterior of the noise reduction plate 8 is provided with micro-perforations 10.

[0031] The sound-absorbing panel 11 is set on the back of the noise reduction plate 8 for secondary noise reduction. The sound-absorbing panel 11 is fixedly installed with sound-absorbing cotton strips 12. The exhaust pipe 3 is covered with a high-temperature sound insulation sleeve 13. The inside of the high-temperature sound insulation sleeve 13 is covered with a sound-absorbing coating 14. The high-temperature sound insulation sleeve 13 is also covered on the exhaust pipe 3 outside the natural gas compressor body 2 to further reduce noise transmission, thereby enabling the natural gas compressor to achieve good noise reduction effect.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the first noise reduction cover 4 and the second noise reduction cover 6 are threadedly connected. The inner frame 7 is symmetrically arranged with respect to the central axis of the second noise reduction cover 6. The first noise reduction cover 4 and the second noise reduction cover 6, which are sleeved on the outside of the natural gas compressor body 2, are easy to install and operate, and do not affect the normal use of the internal natural gas compressor. The number of micro-perforations 10 is set to multiple, and the multiple micro-perforations 10 are evenly distributed on the damping plate 8. When the natural gas compressor body 2 emits noise, the damping plates 8 on both sides first reduce the high frequency of the noise through the multiple micro-perforations 10 on the outside, and then the sound-absorbing glass wool 9 inside the damping plate 8 is used for noise reduction.

[0033] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the high-temperature soundproof sleeve 13 and the sound-absorbing coating 14 are tightly bonded together. The material of the sound-absorbing coating 14 is alumina. The exhaust pipe 3 outside the natural gas compressor body 2 is also fitted with a high-temperature soundproof sleeve 13. The high-temperature soundproof sleeve 13 and the sound-absorbing coating 14 can further reduce noise transmission. The external thread of the first noise reduction cover 4 is threaded through by a fastening bolt 15. The front end of the fastening bolt 15 is threaded to a heat sink 16. Heat sink fins 17 are fixedly installed inside the heat sink 16. Multiple heat sink fins 17 can help the internal temperature of the natural gas compressor body 2 and the first noise reduction cover 4 and the second noise reduction cover 6 to dissipate heat quickly. The number of heat sink fins 17 is set to multiple. The multiple heat sink fins 17 are distributed at equal intervals on the heat sink 16. The overall structure of the heat sink fins 17 is simple and easy to operate. If a fault occurs, it is convenient for maintenance personnel to repair or replace it in time without delaying the normal use of the device.

[0034] The working principle of this utility model is as follows: First, when using the natural gas compressor, connect the external power supply and connect the natural gas pipeline to the outside of the natural gas compressor body 2. Then, install the first noise reduction cover 4 and the second noise reduction cover 6 using double-headed bolts 5. When the natural gas compressor body 2 starts up and receives natural gas for compression, the noise emitted by the natural gas compressor body 2 is reduced by the noise reduction plates 8 located on both sides of the first noise reduction cover 4 and the second noise reduction cover 6 through multiple micro-perforations 10 on the outside. Then, the noise is further reduced by the sound-absorbing glass wool 9 inside the noise reduction plate 8. After the noise is reduced by the noise reduction plate 8, it is transmitted to the sound-absorbing plate 11, where it is absorbed by multiple wave-designed sound-absorbing cotton strips 12 through a gradual change in sound resistance. Subsequently, a high-temperature resistant sound insulation sleeve 13 is also installed on the exhaust pipe 3 outside the natural gas compressor body 2 to further reduce noise propagation, thereby achieving a good noise reduction effect for the natural gas compressor. In this way, through the synergistic effect of the multi-stage noise reduction structure, the noise of the natural gas compressor body 2 during operation can be significantly absorbed and reduced. The noise emitted is controlled, and the overall noise level is manageable, making it suitable for noise-sensitive areas such as hospitals and residential areas, thus broadening the application range of the natural gas compressor body 2. Since the first noise reduction cover 4 and the second noise reduction cover 6 are fitted onto the outside of the natural gas compressor body 2 for noise reduction, heat dissipation brackets 16 and heat dissipation fins 17 can be installed on the first noise reduction cover 4 and the second noise reduction cover 6. Multiple heat dissipation fins 17 can assist in the rapid dissipation of the internal temperature of the natural gas compressor body 2 and the first and second noise reduction covers 4 and 6, thereby ensuring the normal operation of the natural gas compressor. Furthermore, while assisting in heat dissipation, the arrangement of multiple heat dissipation fins 17 also provides a noise reduction function, enhancing the noise reduction effect on the outside of the first and second noise reduction covers 4 and 6. Finally, after completing the installation and use of the natural gas compressor according to the above operations, turn off the switch of the natural gas compressor body 2. If it is not used for a long time, simply disconnect the external power supply. This completes the use of the natural gas compressor with good noise reduction effect.
