Description

Technical Field

[0001] This utility model relates to the field of marine exhaust equipment technology, and in particular to a novel wet silencer exhaust pipe. Background Technology

[0002] A silencer exhaust pipe is a device that reduces exhaust noise through a special structural design. It utilizes the principles of sound wave interference, absorption, and reflection to weaken the noise generated by the exhaust airflow. While reducing noise pollution, it is necessary to balance exhaust resistance to avoid affecting the power performance of the equipment. It is used in the exhaust equipment of ships.

[0003] Shipboard wet muffler exhaust pipes achieve noise reduction by mixing high-temperature exhaust gas with water. Because ship engines have high power and extremely strong exhaust noise, and are often located near residential areas and sensitive waters, strict noise control is required. Water can quickly absorb sound wave energy, while cooling high-temperature exhaust gas, reducing infrared radiation, and preventing exhaust gas from directly impacting the air and generating even greater noise.

[0004] When exhaust pipes discharge gas, the high-speed gas flow generates significant noise, affecting the surrounding environment and people's work and life. In existing technologies, wet exhaust pipes are used to reduce airflow impact by mixing gas and water, which can effectively reduce noise during gas discharge and improve noise pollution. However, in actual use, the gas-liquid contact within the wet exhaust pipe is insufficient, resulting in some gas not fully reacting with water, affecting the purification effect. This can also cause noise to be generated again due to local airflow turbulence, failing to effectively achieve the ideal noise reduction and purification effect. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel wet-type silencer exhaust pipe, which aims to improve the problem that insufficient gas-liquid contact in the existing wet exhaust pipe leads to some gas not fully interacting with water, affecting the purification effect, and causing noise to be generated again due to local airflow turbulence, thus failing to effectively achieve the ideal silencer and purification effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 3 , Figure 4 and Figure 5 An embodiment of this utility model is provided: a novel wet silencer exhaust pipe, including a housing 1, a cap 2 is provided on the right side of the housing 1, a mixing mechanism 3 is provided on the right side of the cap 2, the mixing mechanism 3 is used to mix gas and water, and a silencer mechanism 4 is provided on the inner side of the housing 1, the silencer mechanism 4 is used to silence the gas when it is discharged.

[0034] The mixing mechanism 3 includes a housing 31, the interior of which is used to mix water and gas. The outer wall of the housing 31 is fixedly connected to the inner side of the end cap 2. A support ring 33 is fixedly connected to the inner side of the housing 31, connecting the housing 31 and the air inlet pipe 32. The air inlet pipe 32 is fixedly connected to the inner side of the support ring 33, extending out of the housing 31 on the right side. A hinge 34 is fixedly connected to the top left side of the housing 31, securing the exhaust baffle 35. When the exhaust baffle 35 is impacted by gas, it will open. The bottom of the hinge 34 is fixedly connected to the exhaust baffle 35. The top of the chassis 31 is provided with a water inlet assembly 36, which includes a water inlet pipe 361. The water inlet pipe 361 is connected to the top of the chassis 31. When gas is introduced, water enters the chassis 31 from the water inlet pipe 361 and mixes with the gas. The bottom of the water inlet pipe 361 is fixedly connected to the top of the chassis 31. The top of the chassis 31 is provided with a top hole 362.

[0035] The bottom of the chassis 31 is provided with a water outlet assembly 37, which includes an elbow plate 371. The elbow plate 371 fixes the water outlet pipe 372 at the bottom. The top of the elbow plate 371 is fixedly connected to the bottom of the chassis 31. The right side of the end cap 2 is fixedly connected to the water outlet pipe 372. Excess water is discharged from the water outlet pipe 372. The right side of the air inlet pipe 32 is provided with a connecting assembly 38, which includes an exhaust flange 381. The exhaust flange 381 is used to connect to an external exhaust pipe. The inner side of the exhaust flange 381 is fixedly connected to the right side of the outer wall of the air inlet pipe 32. The right side of the exhaust flange 381 has multiple connecting holes 382, ​​which facilitate the connection of fasteners.

[0036] A fixing component 39 is provided on the right side of the housing 1. The fixing component 39 includes a first docking flange 391, the inner side of which is fixedly connected to the right side of the outer wall of the housing 1. A second docking flange 392 is fixedly connected to the left side of the outer wall of the end cap 2. Fastening components 310 are provided on both the left and right sides of the fixing component 39. The fastening components 310 include multiple bolts 3101, which pass through the first docking flange 391 and the second docking flange 392, fixing the housing 1 and the end cap 2 together. Nuts 3102 are then used to tighten the bolts 3101. 1. The left side of multiple bolts 3101 is threaded to the right side of the mating flange 392. Multiple nuts 3102 are fixedly connected to the left side of multiple bolts 3101. The mixing mechanism 3 also includes multiple fixing blocks 311. The right side of multiple fixing blocks 311 is fixedly connected to the left side of the support ring 33. The adjacent fixing blocks 311 are fixedly connected to the left side of the outer wall of the air inlet pipe 32. The multiple fixing blocks 311 are all chamfered. The fixing blocks 311 strengthen the lateral connection between the air inlet pipe 32 and the support ring 33.

[0037] Specifically, the chassis 31 provides a closed mixing space for water and gas, ensuring that water and gas are fully in contact and mixed inside. The support ring 33 reinforces the connection between the chassis 31 and the air inlet pipe 32, enhancing the stability of the connection and preventing the air inlet pipe 32 from shaking or loosening when gas is introduced. The air inlet pipe 32 serves as a gas delivery channel, stably introducing external gas into the chassis 31 to provide a gas source for the mixing process. The hinge 34 provides a pivot point for the exhaust baffle 35, allowing the exhaust baffle 35 to open and close flexibly. When the gas pressure inside the chassis 31 is too high, the exhaust baffle 35 will be opened by the gas impact, timely venting the gas and balancing the gas pressure inside the chassis 31.

[0038] The water inlet pipe 361 serves as a water supply channel, introducing water into the chassis 31 simultaneously with the gas flow, allowing the water and gas to meet and mix within the chassis 31. The top hole 362 provides fitting space for the installation of the water inlet pipe 361, ensuring that the water inlet pipe 361 can be securely installed on the top of the chassis 31. The elbow plate 371 supports and fixes the connection between the water outlet pipe 372 and the chassis 31, enhancing the structural stability of the water outlet pipe 372 and preventing it from loosening due to water flow impact during drainage. The water outlet pipe 372 can promptly drain excess water mixed within the chassis 31, preventing water accumulation within the chassis 31. The exhaust flange 381 provides an interface for connecting the air inlet pipe 32 to the external exhaust pipe, enabling precise docking. The connection hole 382 allows fasteners to pass through, fixing the exhaust flange 381 to the external exhaust pipe and ensuring no leakage occurs during gas delivery.

[0039] The first docking flange 391 and the second docking flange 392 cooperate with each other to provide a reliable connection structure for the connection between the housing 1 and the end cap 2, enabling them to be accurately docked. The bolt 3101 passes through the first docking flange 391 and the second docking flange 392 to tightly fix the housing 1 and the end cap 2 together, preventing them from separating during use. The nut 3102 cooperates with the bolt 3101 to lock it in place, preventing the bolt 3101 from loosening under vibration and ensuring the stability of the connection between the housing 1 and the end cap 2. The fixing block 311 strengthens the lateral connection between the air inlet pipe 32 and the support ring 33, improving the structural strength of the connection and preventing the air inlet pipe 32 from deforming and breaking due to stress during long-term use.

[0040] Reference Figure 1 , Figure 2 and Figure 3 The silencing mechanism 4 includes a horn cover 41, which is a conical shell with an opening in the middle. Gas is discharged from the opening of the horn cover 41. The outer wall of the horn cover 41 is fixedly connected to the inner side of the housing 1. A water outlet 42 is opened at the bottom of the inner side of the horn cover 41, and some water flows out from the water outlet 42. An exhaust pipe 43 is fixedly connected to the bottom left side of the housing 1. Gas is discharged from the exhaust pipe 43 after passing through the horn cover 41. An exhaust flange 44 is fixedly connected to the bottom of the outer wall of the exhaust pipe 43. The exhaust flange 44 facilitates connection to external pipes.

[0041] Specifically, the horn cover 41 is a conical shell with an opening in the middle, allowing gas to be discharged from the opening and the conical structure to disperse the airflow and reduce noise. The outer wall of the horn cover 41 is fixedly connected to the inner side of the housing 1, providing installation support for itself. The water outlet 42 is opened at the bottom inner side of the horn cover 41, allowing some water to flow out and preventing it from accumulating inside the horn cover 41. The air outlet pipe 43 is fixedly connected to the bottom left side of the housing 1, allowing the gas after passing through the horn cover 41 to be discharged. The air outlet flange 44 is fixedly connected to the bottom outer wall of the air outlet pipe 43, allowing it to be connected to an external pipe to achieve gas discharge.

[0042] Working principle: The housing 1 and the end cap 2 are aligned and connected by connecting flange 1 391 and connecting flange 2 392. Bolt 3101 is passed through the reserved holes of connecting flange 1 391 and connecting flange 2 392. Nut 3102 is threaded onto the left side of bolt 3101 and tightened to achieve a fixed connection between housing 1 and end cap 2. The air inlet pipe 32 is connected to the external exhaust pipe through exhaust flange 381. Fasteners are passed through the connection hole 382 on the right side of exhaust flange 381 and locked to ensure that the gas delivery channel is sealed and stable.

[0043] Install and fix the water inlet pipe 361 through the top hole 362 on the top of the chassis 31 and connect it to the external water supply equipment. At the same time, connect the air outlet flange 44 at the bottom of the air outlet pipe 43 to the external subsequent pipeline to complete the pipeline assembly. External gas enters the inside of the chassis 31 through the air inlet pipe 32, and water is simultaneously introduced into the chassis 31 through the water inlet pipe 361. Water and gas are fully contacted and mixed inside the chassis 31.

[0044] If the gas pressure inside the casing 31 is too high, the gas impacts the exhaust baffle 35, causing the exhaust baffle 35 to rotate around the hinge 34 and open, releasing excess gas to balance the internal gas pressure. After the pressure is restored, the exhaust baffle 35 resets and closes. Excess water generated during the mixing process is discharged through the water outlet pipe 372. The elbow plate 371 provides stable support for the water outlet pipe 372, preventing the water flow from impacting and causing the water outlet pipe 372 to loosen. Afterward, the mixed gas enters the horn cover 41 inside the casing 1. The conical structure of the horn cover 41 disperses the airflow and reduces the noise during gas flow. Some water droplets carried in the gas flow out through the water outlet hole 42 at the bottom inside the horn cover 41, preventing water from accumulating inside the horn cover 41 and affecting the noise reduction effect. The gas that has undergone noise reduction treatment is discharged from the opening of the horn cover 41, enters the exhaust pipe 43, and then is introduced into the external subsequent pipeline through the exhaust flange 44.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
