Description

Technical Field

[0001] The invention relates to the technical field of pipeline noise reduction, and in particular to a gas pipeline silencer. Background Art

[0002] Pipelines are the main carrier for natural gas transportation. During the pipeline transportation process, when the flow state of natural gas changes suddenly, it will produce obvious noise, which will pose a serious threat to the physical and mental safety of operators. Therefore, silencers are usually installed on the compressor or intake and exhaust systems on the pipeline to reduce the noise when natural gas flows through these devices.

[0003] At present, most of the silencers on the market that are specifically used for pipeline noise reduction do not have filtering functions. Impurities carried in natural gas can easily clog the small holes in the silencer, making the noise reduction effect of the silencer worse and increasing the cost and difficulty of subsequent maintenance. Summary of the invention

A gas filter assembly and a silencer are sequentially spaced in an inner cavity of the silencer from one end close to the air intake pipe section to the other end.

[0007] The beneficial effects of the present invention are: simple and reasonable structural design, capable of effectively filtering natural gas impurities while reducing noise, avoiding clogging of silencer components, having good noise reduction effect and low maintenance cost.

[0012] The beneficial effect of adopting the above further solution is that the silencer is reasonably designed, and the gas expands when entering the muffler cavity with a variable diameter, effectively reducing the energy carried by the gas.

[0013] Furthermore, a sound-absorbing layer is provided on the inner surface of the sound-absorbing cavity.

[0014] The beneficial effect of adopting the above further solution is that the energy absorption and sound reduction effect of the sound-absorbing chamber can be improved.

[0015] Furthermore, the sound-absorbing layer is sound-absorbing cotton.

[0016] The beneficial effect of adopting the above further solution is good noise reduction effect.

[0017] Furthermore, the muffler is a cylindrical structure, and the air intake pipe section and the exhaust pipe section are coaxially connected to the middle of the two ends thereof.

[0019] Furthermore, a pipe opening at one end of the air inlet pipe section extends inwardly into the muffler, and a diverter is connected to the pipe opening of this section.

[0020] The beneficial effect of adopting the above further solution is that the gas entering the muffler is dispersed, so that the gas enters the muffler evenly and is fully contacted with the gas filter component for filtration.

[0032] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] Example: Figures 1 to 3 As shown, the gas pipeline silencer device of this embodiment includes a silencer 1, which is horizontally arranged, one end of which is connected to an air intake pipe section 11, and the other end is connected to an exhaust pipe section 12. In the inner cavity of the silencer 1, a gas filter assembly 2 and a silencer 3 are sequentially spaced from one end close to the air intake pipe section 11 to the other end.

[0034] The silencing process is as follows:

[0035] Natural gas enters the silencer 1 from the air inlet pipe section 11, and then flows through the gas filter component 2. During this process, impurities carried by the natural gas will also be filtered and adsorbed by the gas filter component 2. After the impurities are removed, the natural gas passes through the silencer 3 to reduce the energy carried by the gas and eliminate noise. Finally, the natural gas is discharged through the exhaust pipe. The structural design of the entire device is simple and reasonable. It can effectively filter natural gas impurities while reducing noise, avoid clogging of silencer components, have good noise reduction effect, and have low maintenance costs.

[0036] As a preferred embodiment, the gas filter assembly 2 is a filter plate with holes, the edge of the filter plate is sealed and connected to the inner wall of the muffler, and the filter plate is evenly distributed with a plurality of tortuous flow channels penetrating therethrough at both ends.

[0037] In this embodiment, the filter plate is made of a filter material as a whole, or is filled with filter fillers. When natural gas flows through the gas filter assembly 2, the natural gas can pass through the flow channel of the filter plate or through the filter material (filter plate body). The gas will collide with the filter material, and the impurities carried will also be adsorbed by the filter material, with a good adsorption effect. The tortuous flow channel can reduce the energy of the gas when passing through the gas filter assembly 2, and the passing time is also increased, thereby improving the filtering effect.

[0038] As a preferred embodiment, Figure 2 As shown, the muffler 3 is a muffler plate, the edge of which is sealed and connected to the inner wall of the muffler tube 1, and the muffler plate is evenly distributed with a plurality of muffler cavities 31 penetrating therethrough at both ends, and the longitudinal cross-sectional area of ​​the muffler cavity 31 gradually increases from both ends to the middle.

[0039] In this embodiment, when the gas flows through the silencer plate, it enters the silencer cavity 31 on the silencer plate. Since the silencer cavity 31 is small at both ends and large in the middle, the gas will expand in the silencer cavity 31, reducing the energy carried by the gas, thereby achieving the purpose of silencing and noise reduction. The design is simple and reasonable, and the silencing and noise reduction effect is good.

[0040] As a preferred embodiment, a sound-absorbing layer 32 is provided on the inner surface of the sound-absorbing cavity 31 .

[0041] In this embodiment, when the natural gas passes through the muffler chamber 31 , the muffler layer 32 on the wall of the muffler chamber 31 absorbs the noise generated by the natural gas, further improving the muffler effect of the muffler 3 .

[0042] As a preferred implementation, the sound-absorbing layer 32 is sound-absorbing cotton.

[0043] In this embodiment, the sound-absorbing cotton has a good attraction effect.

[0044] As a preferred embodiment, the muffler 1 is a cylindrical structure, and the air intake pipe section 11 and the exhaust pipe section 12 are coaxially connected to the middle of the two ends thereof.

[0045] In this embodiment, the entire silencer has a regular and beautiful appearance and is easy to produce and process.

[0046] As a preferred embodiment, one end of the air inlet pipe section 11 extends inwardly into the muffler 1, and a diverter 4 is connected to the end of the pipe section.

[0047] In this embodiment, when natural gas enters the muffler 1 through the air intake pipe section 11, when passing through the diverter 4, the gas enters the muffler 1 in a diffused and uniform manner due to the blocking effect of the diverter 4 on the airflow, which to a certain extent reduces the energy of the natural gas airflow. At the same time, it can prevent a relatively concentrated airflow from entering the muffler 1 and impacting other internal components, that is, it plays a role in unloading energy.

[0048] As a preferred embodiment, the diverter 4 includes a diverter cover 41 with one end open, the open end of the diverter cover 41 is sealed and connected to one end of the air intake pipe section 11, and a plurality of diverter branches 42 connected to the interior are evenly spaced on the bottom wall and the outer periphery of the diverter cover 41.

[0049] In this embodiment, when natural gas enters the muffler 1 through the air intake pipe section 11, when passing through the diverter hood 41, the gas quickly diffuses from the center to the edge due to the blocking effect of the diverter hood 41 on the airflow, and evenly enters the muffler 1 through multiple diverter branches 42, so that the gas can fully contact and filter with the gas filter assembly 2 after entering the muffler 1.

[0050] As a preferred embodiment, the air intake pipe section 11 and the exhaust pipe section 12 are respectively connected with support components 5 for improving the vibration inside the entire muffler device under airflow conditions.

[0051] In this embodiment, the support assembly 5 can provide good support for the entire device and can also improve the vibration caused by airflow passing through the device.

[0052] As a preferred embodiment, Figure 3As shown, the support assembly 5 includes a first protective layer 51 and a second protective layer 52 respectively wrapped around the outside of the intake pipe section 11 and the exhaust pipe section 12 from the inside to the outside, and a hoop 53 clamped on the outside of the second protective layer 52, the lower end of the hoop 53 is connected to a vertical connecting rod 54, and the lower end of the connecting rod 54 is provided with a deformable first bottom plate 55 and a non-deformable second bottom plate 56 from top to bottom, the first protective layer 51 and the second protective layer 52 are respectively a polyurethane foam plastic layer and a fireproof material layer, and when in use, the second bottom plate 56 is connected and fixed to other carriers.

[0053] The first protective layer 51 makes the connection between the hoop 53 and the corresponding pipe section tighter, and the second protective layer 52 is flame retardant, isolating the possible temperature rise at the connection caused by the relative movement between the hoop 53 and the pipe section, thereby improving safety performance.

[0054] In this embodiment, the first bottom plate 55 is deformable, and can dissipate energy and eliminate vibration generated by the device when air flows through the device, thereby reducing the amplitude of the vibration.

[0055] In the above embodiment, the hoop member 53 is composed of two semicircular hoops, which are respectively clamped on both sides of the corresponding pipe section, and the two ends of the two hoops are respectively connected by bolts passing through the two hoops, so that the hoop member 53 is stably and firmly clamped outside the corresponding pipe section, and the two joints of the hoop member 53 are respectively distributed up and down, and the upper end of the connecting rod 54 is clamped between the clamps at the lower ends of the two hoops (that is, the connection between the two ends), and the bolts there pass through the connecting rod 54.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
