Description

Technical Field

[0001] This utility model relates to the field of silencer technology, and in particular to a hybrid silencer. Background Technology

[0002] Diesel generator sets consist of many systems, with the exhaust system being a major component. The muffler within the exhaust system is a crucial noise reduction element, effectively lowering the generator set's exhaust noise. The muffler can be installed in different ways depending on the application environment, with top-mounted installation being a commonly used method.

[0003] In practical applications, sometimes the size of the muffler is limited during installation. Achieving good noise reduction under such limited size is a technical problem that needs to be solved. Therefore, it is necessary to design new silencers. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, a hybrid silencer is proposed.

[0005] The specific technical solution is as follows: A hybrid silencer; mainly comprising: a housing; The interior of the box is divided into a first column and a second column. The first column is divided into four spaces: space one, space three, space five and space seven. The second column is divided into three spaces: space two, space four and space six. Spaces two and five are filled with a first sound-absorbing material. Smoke can be vented between spaces one and three, between spaces two and one, but not between spaces two and four. Smoke can be vented between spaces three and four, but not between spaces three and five. Smoke can be vented between spaces four and six, between spaces five and six, between spaces six and seven, and between spaces five and seven.

[0006] The aforementioned hybrid silencer also has the following feature: the first space is provided with a first inlet and outlet for exhaust smoke, and the seventh space is provided with a second inlet and outlet for exhaust smoke.

[0007] The aforementioned hybrid silencer also has the following feature: the inlet and outlet directions of the first inlet and outlet are arranged parallel to the column direction, and the inlet and outlet directions of the second inlet and outlet are arranged intersecting with the column direction.

[0008] The aforementioned hybrid silencer also features that both the first inlet and the second inlet are equipped with mounting flanges.

[0009] The aforementioned hybrid silencer also has the following characteristics: the first space and the second space are aligned at both ends in the direction of the smoke exhaust flow; the third space and the fourth space are aligned at both ends in the direction of the smoke exhaust flow; and the combined length of the fifth space and the seventh space is aligned at both ends in the direction of the smoke exhaust flow of the sixth space.

[0010] The aforementioned hybrid silencer also features the following characteristics: the sides of spaces three, four, and six that overlap with the housing are all provided with a second sound-absorbing material, and the sides of spaces one and seven that overlap with the housing are also provided with the second sound-absorbing material.

[0011] The aforementioned hybrid silencer also features the following characteristics: a partition 1 is provided between space 1 and space 2; a partition 1 is provided between space 1 and space 3; a partition 3 is provided between space 3 and space 4; a partition 4 is provided between space 3 and space 5; a partition 5 is provided between space 2 and space 4; a partition 6 is provided between space 4 and space 6; and a partition 7 is provided between space 5 and space 7.

[0012] The aforementioned hybrid silencer also features that the fifth and fourth partitions are configured as sealing plates.

[0013] The aforementioned hybrid silencer also has the following features: a partition 8 is provided between space 5 and space 7 together and space 6; or a partition 9 is provided between space 5 and space 6, and a partition 10 is provided between space 6 and space 7.

[0014] The aforementioned hybrid silencer also features that partition 1, partition 5, partition 3, partition 4, partition 6, partition 8, partition 9, partition 10, and partition 7 are all provided with through holes.

[0015] The positive effects of the above technical solution are: This utility model provides a hybrid muffler that effectively reduces engine exhaust noise by changing different exhaust paths. It achieves good noise reduction effect under the condition of limited size, and can reduce exhaust noise by 30-35 decibels.

[0016] Specifically, when the generator set is running, the exhaust gas from the engine enters space one of the muffler. After passing through space one, part of the noise is absorbed by space two. Then the exhaust gas enters space three, where it is blocked by the sound absorption of space five. After that, the exhaust gas turns to space four, and the noise is also attenuated during the path change. Finally, the exhaust gas enters space six, where some of the noise is absorbed by space five. The exhaust gas hits the end wall, changes its route, and absorbs some more noise. Finally, the exhaust gas is discharged from space seven. Attached Figure Description

[0023] Optionally, the box can be a cuboid structure.

[0024] The interior of the box is divided into a first column and a second column. The first column is divided into four spaces: Space 1, Space 3, Space 5, and Space 7. The second column is divided into three spaces: Space 2, Space 4, and Space 6. The space 2 and the space 5 are filled with a first sound-absorbing material 11. Smoke can be vented between the space 1 and the space 3. Smoke can be vented between the space 2 and the space 1. Smoke cannot be vented between the space 2 and the space 4. Smoke can be vented between the space 3 and the space 4. Smoke cannot be vented between the space 3 and the space 5. Smoke can be vented between the space 4 and the space 6. Smoke can be vented between the space 5 and the space 6. Smoke can be vented between the space 6 and the space 7. Smoke can be vented between the space 5 and the space 7.

[0025] Optionally, in one specific embodiment, a partition 12 is provided between space 1 and space 2, a partition 2 13 is provided between space 1 and space 3, a partition 34 is provided between space 3 and space 4, a partition 4 35 is provided between space 3 and space 5, a partition 5 24 is provided between space 2 and space 4, a partition 6 46 is provided between space 4 and space 6, and a partition 7 57 is provided between space 5 and space 7.

[0026] The partition 24 and the partition 35 are configured as sealing plates to prevent smoke from passing through.

[0027] Optionally, in one embodiment, a partition 8 567 is provided between the space 5 and the space 7 together and the space 6; or, alternatively, in another embodiment, a partition 9 56 is provided between the space 5 and the space 6, and a partition 10 67 is provided between the space 6 and the space 7.

[0028] Optionally, in this embodiment, partition 12, partition 5 24, partition 3 34, partition 4 35, partition 6 46, partition 8 567, partition 9 56, partition 10 67, and partition 7 57 are all provided with through holes. The partitions with through holes can be perforated plates or mesh plates.

[0029] Optionally, in this embodiment, space 1 is provided with a first inlet / outlet 21 for smoke exhaust, and space 7 is provided with a second inlet / outlet 72 for smoke exhaust. It should be noted that both the first inlet / outlet 21 and the second inlet / outlet 72 are inlets / outlets, serving as both entrances and exits, and can be installed as needed to adapt to various different scenarios.

[0030] Optionally, such as Figure 1 As shown, in one specific embodiment, the entry / exit direction of the first inlet / outlet 21 is parallel to the column direction, and the entry / exit direction of the second inlet / outlet 72 is intersecting the column direction. For example, in this embodiment, the entry / exit direction of the second inlet / outlet 72 is perpendicular to the column direction.

[0031] Preferably, such as Figure 1 As shown, the sides of spaces 3, 4, and 6 that overlap with the enclosure are all provided with a second sound-absorbing material 32. The sides of spaces 1 and 7 that overlap with the enclosure are also provided with the second sound-absorbing material 32. Wherein, as Figure 1 As shown, the sides of space 1 and space 3 that are aligned with each other are also provided with a second sound-absorbing material 32, and the sides of space 7 and space 6 that are aligned with each other are also provided with a second sound-absorbing material 32. Figure 1 As shown, in this embodiment, the first inlet / outlet 21 is provided on the side where space 1 and space 2 are aligned. The size of the side where space 1 and space 2 are aligned is not significantly different from the size of the first inlet / outlet 21. Therefore, no second sound-absorbing material 32 is provided on the side where space 1 and space 2 are aligned. In fact, in other embodiments, the second sound-absorbing material 32 can be provided at a position on the side where space 1 and space 2 are aligned, which is not part of the first inlet / outlet 21. For example... Figure 1As shown, in this embodiment, the second inlet / outlet 72 is provided on the side of space 7 7 that is aligned with space 5 5. Since the dimensions of the side of space 7 7 7 and space 5 5 aligned with the dimensions of the second inlet / outlet 72 are the same, the second sound-absorbing material 32 is not provided on the side of space 7 7 7 and space 5 5 aligned with the second inlet / outlet 72. Optionally, in other embodiments, the second sound-absorbing material 32 can be provided at a position on the side of space 7 7 7 and space 5 5 that is not part of the second inlet / outlet 72. Specifically, a plate structure parallel to the corresponding side can be provided inside the enclosure, and the plate structure has through holes. This design can achieve sound absorption and noise reduction, increasing the sound absorption and noise reduction effect.

[0032] Furthermore, both the first inlet / outlet 21 and the second inlet / outlet 72 are provided with mounting flanges 2172.

[0033] This utility model provides a hybrid silencer 200, which is used as follows: Figure 2 As shown, when the generator set 100 is running, the exhaust gas from the engine 101 enters the muffler space 1. After passing through space 1, part of the noise is absorbed by space 2. Then the exhaust gas enters space 3, where it is blocked by the sound absorption of space 5. After that, the exhaust gas turns to space 4, where the noise is also attenuated during the path change. Finally, the exhaust gas enters space 6, where some of the noise is absorbed by space 5. The exhaust gas hits the end wall, changes its route, and absorbs some more noise. Finally, the exhaust gas enters the external pipe 300 through space 7 and is discharged.

[0034] The present invention provides a hybrid muffler 200, which effectively reduces the exhaust noise of engine 101 by changing different exhaust paths. It achieves a good noise reduction effect under the condition of limited size, and can reduce exhaust noise by 30-35 decibels.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
