Description

Technical Field

[0001] The utility model relates to the field of pressure relief of pressure vessels, in particular to an automatic noise reduction device for relief of pressure in high-pressure vessels. Background Art

[0002] In industrial production and laboratory applications, high-pressure vessels are widely used to store and process gases or liquids. During the depressurization process of high-pressure vessels, that is, the pressure release process, if appropriate control measures are not taken, a series of problems will arise: the rapidly released high-pressure gas will rub against the exhaust pipe wall, and the high pressure difference will cause the gas to expand rapidly, generating strong airflow dynamic noise. This noise not only interferes with the working environment, but also may cause hearing damage to workers who are exposed to this environment for a long time. High-speed airflow has a large kinetic energy, which may cause physical harm to people around the exhaust port and cause impact damage to the equipment. In addition, the rapid release of gas may also cause a sudden drop in the ambient temperature, causing condensation or even ice on the surface of the equipment, affecting the normal operation of the equipment, and may trigger more serious production safety accidents. Rapidly discharged gas may also have adverse effects on the surrounding environment. For example, when the gas contains harmful components, uncontrolled discharge may pose a threat to the surrounding environment and personnel health.

[0003] To address these problems, existing solutions include using simple mufflers or increasing the complexity of the exhaust pipe to disperse the airflow, but these methods are often limited in effect and cannot simultaneously solve the problems of noise reduction, safety risks, environmental protection, and energy utilization. Therefore, it is particularly necessary to develop a new type of automatic noise reduction device for depressurizing high-pressure vessels that can effectively meet the above challenges.

[0026] The utility model is described in detail below in conjunction with the accompanying drawings.

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] Embodiment 1

[0029] In this embodiment, if Figure 1 , 2 As shown, an automatic noise reduction device for depressurizing a high-pressure container comprises: an exhaust pipe 1, a connector 2 and a rotating air pipe 3, wherein the connector 2 is used to connect the exhaust pipe 1 and the high-pressure container, and the rotating air pipe 3 can be rotatably and tightly sleeved on the outside of the exhaust pipe 1, and matching exhaust holes 4 are evenly arranged on the surfaces of the exhaust pipe 1 and the rotating air pipe 3.

[0030] When the rotating air pipe 3 rotates, its exhaust hole 4 is opened and closed with the exhaust hole 4 of the exhaust pipe 1. When in the "0" position, the exhaust holes 4 are completely staggered to achieve sealing without air leakage. After rotation, the positions of the exhaust holes 4 can be completely matched, and each exhaust hole 4 is connected to realize the exhaust function.

[0031] The design of the device makes full use of the interaction between the exhaust pipe 1 and the rotating air pipe 3, and realizes uniform gas discharge through the matching exhaust hole 4. The exhaust pipe 1 is tightly connected to the high-pressure container through the connector 2 to ensure effective gas transmission. The rotating air pipe 3 is rotatably sleeved on the outside of the exhaust pipe 1, and its design allows the exhaust hole 4 to be opened and closed by the motor 6, thereby adjusting the exhaust volume and speed, and effectively reducing the noise when the pressure is released.

[0032] Furthermore, the rotating air pipe 3 is connected to a motor 6 for driving the rotating air pipe 3 to rotate relative to the exhaust pipe 1;

[0033] Furthermore, it also includes a control system 5, and the motor 6 is electrically connected to the control system 5, and the control system 5 controls the operation of the motor 6; the introduction of the motor 6 enables the rotation of the air pipe 3 to be precisely controlled, and the rotation of the relative exhaust pipe 1 is directed by the control system 5 as needed. This design not only improves the flexibility and convenience of operation, but also can be dynamically adjusted according to the actual working pressure and noise level, so as to achieve more precise control of the depressurization process.

[0034] Furthermore, the control system 5 is electrically connected to a noise detection device 7 for detecting noise emitted by the equipment;

[0035] Furthermore, the control system 5 is electrically connected to a wind pressure detection device 8 for detecting the decompression pressure of the equipment; the control system is connected to the noise detection device 7 and the wind pressure detection device 8 to monitor the noise level and gas pressure in the working environment in real time to ensure that the operation is carried out within a safe range. When the detected noise or pressure exceeds the preset threshold, the control system 5 will automatically adjust the motor 6 to optimize the exhaust area, which not only protects the working environment but also maintains the safe operation of the equipment.

[0036] Furthermore, a multi-layer exhaust box 9 is disposed outside the rotating air pipe 3 ; in this embodiment, a two-layer box 9 is disposed outside the rotating air pipe 3 .

[0037] Furthermore, the surface of the box 9 is provided with uniform pores, and a sound-absorbing cotton 10 is provided inside. The design of the multi-layer exhaust box 9, combined with the sound-absorbing cotton 10 filled inside, further reduces the noise generated during the exhaust process. The uniform pores on the surface of the box 9 ensure the smooth discharge of gas, while reducing the impact of high-speed airflow on the surrounding environment, achieving a high-efficiency noise reduction effect.

[0038] Furthermore, a manual adjustment device 11 is provided at one end of the rotating air pipe 3, and the manual adjustment device 11 is provided with a marking line for marking the relative position of the rotating air pipe 3 and the exhaust pipe 1. The manual adjustment device 11 provides additional convenience for the use of the device, especially when fine adjustment of the exhaust volume is required or intervention is required under special circumstances. The design of the marking line allows the user to intuitively understand the relative position of the rotating air pipe 3 and the exhaust pipe 1, thereby achieving more precise control and adjustment; at the same time, when a fault occurs, it can be manually closed to avoid danger.

[0039] Furthermore, sealing devices are provided at both ends of the exhaust pipe 1 and the rotating air pipe 3; the sealing devices at both ends of the exhaust pipe 1 and the rotating air pipe 3 effectively prevent gas leakage during the high-pressure exhaust process and ensure the sealing performance of the device. This feature is crucial for maintaining a stable working environment and preventing possible dangers and pollution.

[0040] Embodiment 2

[0041] On the basis of the first embodiment, the rotating air pipe 3 and the exhaust pipe 1 are provided with matching spiral grooves and positioning blocks, so that the rotating air pipe 3 and the exhaust pipe 1 can move axially when sliding relative to each other, and the opening of the exhaust hole 4 can be adjusted more efficiently.

[0042] Specific working method: The silencer has the function of automatic noise monitoring, alarm and adjustment. Before the gas is connected to the device, the power supply of the device should be turned on, the noise control value during exhaust should be set on the control module, and the motor 6 should be checked to be at the starting "0" position; the gas that needs to be depressurized is connected to the device to make the gas enter the exhaust pipe 1. At this time, the automatic adjustment button is started on the control module, and the motor 6 starts to rotate forward with a certain step length. The rotating air pipe 3 starts to rotate slowly on the exhaust pipe 1. As the air holes on the exhaust pipe 1 and the air holes on the rotating air pipe 3 are connected, and the ventilation area continues to increase, a large amount of gas begins to be evenly sprayed around and is controlled in the central part of the device. The gas energy is released for the first time, which will generate a lot of noise. At this time, each time the gas passes through a layer of box 9, the energy will be gradually absorbed, and the remaining energy will be released into the larger space of the outer layer. The noise will also decrease layer by layer until it is released into the external environment of the device.

[0043] During the exhaust process, the control module on the top of the device will automatically monitor the noise around the device and the exhaust pressure at the device outlet. When the noise value exceeds the set value, the device will send out an audible and visual alarm signal, and automatically control the motor 6 to drive the rotating air pipe 3 to reduce the total exhaust area, so as to control the noise within a certain range; if the control module automatically monitors that the noise value around the device exceeds the set value, the motor 6 will continue to rotate forward until it rotates to the maximum angle, completely connecting the air holes on the exhaust pipe 1 and the air holes on the rotating air pipe 3, so as to achieve the maximum total exhaust area of ​​the device.

[0044] 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 and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
