Description

Technical Field

[0001] This utility model relates to the field of silencer technology, and in particular to a silencer that combines a small hole and a sound flow. Background Technology

[0002] In numerous industrial sectors, including light industry, chemical industry, petrochemical industry, coal chemical industry, fine chemical industry, pharmaceutical chemical industry, and daily chemical industry, compressed air, nitrogen, oxygen, hydrogen, helium, and syngas from chemical plants are widely used. During the application of these gases, large quantities of waste gas are frequently generated that require venting. However, the emission of these waste gases produces significant noise, adversely affecting the surrounding environment and people. To reduce this venting noise, silencers are commonly used in industry to reduce noise in exhaust pipes.

[0003] Currently, there are many types of mufflers on the market, with various internal structures designed to meet different pressure and exhaust volume requirements. These mufflers primarily achieve noise reduction by absorbing, reflecting, or interfering with sound waves through changes in their internal structure. Common muffler structures include resistive mufflers, reactive mufflers, and composite mufflers that combine both.

[0004] However, with existing technology, when dealing with large flow rates and high pressures of gas, the airflow distribution inside the silencer is often uneven, resulting in poor noise reduction in certain areas and severe gas flow deviation, which in turn generates significant noise and vibration. Utility Model Content

[0005] The purpose of this invention is to provide a silencer that combines a small hole with a sound flow, which solves the problem that in the prior art, when dealing with large flow and high pressure gases, the airflow distribution inside the silencer is often uneven, resulting in poor noise reduction effect in some areas, serious gas flow deviation, and thus generating greater noise and vibration.

[0006] To achieve the above objectives, this utility model provides a small-hole and sound flow combined silencer, including an outer cylinder, a bottom sealing plate, a drain pipe, a silencer cylinder, an elliptical perforated end cap, an internal flow divider, and an outlet flow divider. The bottom sealing plate is fixedly connected to the outer cylinder and located below it. The drain pipe is fixedly connected to the bottom sealing plate and located below it. The silencer cylinder is fixedly connected to the bottom sealing plate and located above it. The elliptical perforated end cap is fixedly connected to the silencer cylinder. Located above the silencer, the silencer and the elliptical perforated head have a plurality of evenly distributed round holes on their surfaces. The internal diverter is located in the middle section of the outer cylinder, and the outlet diverter is located above the outer cylinder. The outlet diverter includes two first steel plates and a wire mesh. The two first steel plates are fixedly connected to the outer cylinder and located at the upper end of the outer cylinder. Both first steel plates are S-shaped. The wire mesh is fixedly connected to the two first steel plates and located above the two first steel plates.

[0007] The internal diverter includes two second steel plates, which are fixedly connected to the outer cylinder and disposed inside the outer cylinder. The two second steel plates are arranged in a cross shape.

The outer sound flow silencer assembly is fixedly connected to the outer cylinder and is disposed inside the outer cylinder. The two ends of the inner sound flow silencer assembly are fixedly connected to the first steel plate and the second steel plate respectively, and are located between the first steel plate and the second steel plate.

[0009] The small hole and sound flow combined silencer also includes an air inlet pipe and a flange. The air inlet pipe is fixedly connected to the bottom sealing plate and is located below the bottom sealing plate. The flange is fixedly connected to the air inlet pipe and is located below the air inlet pipe.

The elliptical perforated end cap cooperates with the silencer and performs initial diversion through the circular holes on the cylinder wall, dispersing the high-flow, high-pressure airflow into multiple small streams, reducing the airflow speed and directionality, thereby reducing airflow impact and noise. After being silenced, the gas is evenly divided into four streams through the two first steel plates and the airflow direction is changed to avoid vibration and flow deviation caused by straight inflow and outflow.

Detailed Implementation

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] Please see Figures 1 to 2 This utility model provides a combined silencer with a small hole and sound flow, including an outer cylinder 1, a bottom sealing plate 2, a drain pipe 3, a silencer cylinder 4, an elliptical perforated end cap 5, an internal flow divider 6, and an outlet flow divider 7. The bottom sealing plate 2 is fixedly connected to the outer cylinder 1 and located below it. The drain pipe 3 is fixedly connected to the bottom sealing plate 2 and located below it. The silencer cylinder 4 is fixedly connected to the bottom sealing plate 2 and located above it. The elliptical perforated end cap 5 is fixedly connected to the silencer cylinder 4 and located below it. Above the silencer 4, the silencer 4 and the elliptical perforated end cap 5 are provided with a plurality of evenly distributed round holes 8. The internal diverter 6 is located in the middle section of the outer cylinder 1, and the outlet diverter 7 is located above the outer cylinder 1. The outlet diverter 7 includes two first steel plates 9 and a wire mesh 10. The two first steel plates 9 are fixedly connected to the outer cylinder 1 and are located at the upper end of the outer cylinder 1. Both first steel plates 9 are S-shaped. The wire mesh 10 is fixedly connected to the two first steel plates 9 and is located above the two first steel plates 9.

[0018] In this embodiment, the gas first enters the interior of the silencer 4. The elliptical perforated end cap cooperates with the silencer 4 and performs initial diversion through the circular holes 8 on the cylinder wall, dispersing the high-flow-rate, high-pressure airflow into multiple smaller streams, reducing the airflow speed and directionality, thereby reducing airflow impact and noise. After being silenced, the gas is evenly divided into four streams through the two first steel plates 9 and the airflow direction is changed to avoid vibration and flow deviation caused by straight inflow and outflow. At the same time, the S-shaped design increases the residence time of the gas in the silencer, which helps to further reduce airflow noise.

[0019] Furthermore, the internal diverter 6 includes two second steel plates 11, which are fixedly connected to the outer cylinder 1 and disposed inside the outer cylinder 1. The two second steel plates 11 are arranged in a cross shape.

[0020] In this embodiment, the incoming airflow is evenly divided into four streams, which enter the interior of the outer cylinder 1 respectively. This helps to further reduce the airflow speed and pressure, allowing the airflow to pass through the silencing component more smoothly and improving the silencing efficiency.

[0021] Furthermore, the small hole and sound flow combined silencer also includes an inner sound flow silencing assembly 12 and an outer sound flow silencing assembly 13. The outer sound flow silencing assembly 13 is fixedly connected to the outer cylinder 1 and is disposed inside the outer cylinder 1. The two ends of the inner sound flow silencing assembly 12 are fixedly connected to the first steel plate 9 and the second steel plate 11 respectively, and are located between the first steel plate 9 and the second steel plate 11.

[0022] In this embodiment, the external sound flow silencing assembly 13 is responsible for processing the airflow from the silencer 4 to perform the first stage of silencing, while the internal sound flow silencing assembly 12 receives the airflow after it has been evenly divided by the internal distributor 6 to perform the second stage of more refined silencing. The double-sleeve design increases the airflow channel and the space for laying the silencing cotton, thereby improving the silencing effect.

[0023] Furthermore, the small hole and sound flow combined silencer also includes an air inlet pipe 14 and a flange 15. The air inlet pipe 14 is fixedly connected to the bottom sealing plate 2 and is located below the bottom sealing plate 2. The flange 15 is fixedly connected to the air inlet pipe 14 and is located below the air inlet pipe 14.

[0024] In this embodiment, the flange 15 serves as a connecting component for fixing the muffler to the gas emission pipe, while the air inlet pipe 14 is the channel through which gas enters the muffler, guiding the exhaust gas from the pipe into the interior of the muffler for treatment.

[0025] Furthermore, the combined small hole and sound flow silencer also includes a hanging lug 16, a herringbone rain cover 17, two support plates 18, and two support legs 19. The hanging lug 16 is fixedly connected to the outer cylinder 1 and is located above the outer cylinder 1. The herringbone rain cover 17 is fixedly connected to the outer cylinder 1 and covers the outer cylinder 1. The two support plates 18 are fixedly connected to the outer cylinder 1 and are located on both sides of the outer cylinder 1. The two support legs 19 are respectively fixedly connected to the corresponding support plates 18 and are located below the corresponding support plates 18.

[0026] In this embodiment, the herringbone rain cover 17 is installed on the top of the muffler to protect it from wind and rain, prevent rainwater from directly entering the muffler, protect the internal components from moisture, and extend the service life of the equipment. The support leg 19 is used to fix the muffler to the ground in the area of ​​use to ensure stable operation of the equipment.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model.
