Description

Technical Field

[0001] The utility model relates to the field of pressure relief of pressure vessels, and particularly relates to a portable pressure relief device for pressure vessels. Background Art

[0002] In the prior art, the pressure relief process of a pressure vessel usually involves gradually releasing the pressure from a high-pressure state to atmospheric pressure. This process not only requires precise control to avoid damage to the equipment caused by pressure fluctuations, but also needs to ensure the safety of operators and consider environmental protection. The traditional pressure relief methods or devices have the following disadvantages in actual operation:

[0003] During the rapid pressure release process, when the gas passes through a narrow outlet, it will generate sharp and high-decibel sounds, which pose a threat to the hearing health of on-site workers. Long-term exposure to such an environment may lead to occupational hearing damage. Due to its fixed design, the traditional pressure relief device lacks flexibility and cannot quickly adapt to pressure vessels of different shapes and sizes. In emergency situations, such as when it is necessary to quickly reduce the pressure, this rigid design may not provide sufficient safety, increasing the risk of accidents. In addition to noise, the pressure relief process may also be accompanied by the emission of pollutants such as oil mist and dust, which pollute the environment and may cause chronic effects on the surrounding ecosystem and personnel health in the long term. The operation of traditional pressure relief devices often requires professional skills and experience, and the operation steps are complex, requiring multiple people to cooperate to complete. In the absence of professional personnel, incorrect operation may lead to pressure relief failure or exacerbate the above problems. Since traditional pressure relief devices are mostly large-scale fixed equipment, their maintenance and replacement of consumables (such as sound-absorbing materials) often require a professional team, which increases the operating cost, especially in the case of frequent maintenance and replacement of consumables.

[0004] The purpose of the present utility model is to solve the above problems, and provides a portable pressure relief device for pressure vessels. This device adopts a modular design, is easy to assemble and disassemble, and at the same time has efficient sound-absorbing and environmental protection functions, improves the safety and convenience of pressure relief operations, reduces the operation and maintenance costs, and can flexibly adapt to the needs of different application scenarios and pressure vessels.

[0026] The following will describe the present utility model in detail with reference to the accompanying drawings.

[0027] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0028] A portable pressure vessel pressure relief device includes: an internal sound insulation unit 1 and a box body 2. One end of the internal sound insulation unit 1 is provided with a connecting pipe 3 for connecting to a pressure vessel. The connecting pipe 3 is provided with an external thread. The outer diameter of the body of the internal sound insulation unit 1 is greater than the outer diameter of the connecting pipe 3. The box body 2 is provided with bolt holes corresponding to the connecting pipe 3. In the petrochemical industry, it is necessary to regularly release the pressure of various pressure vessels. When using the pressure relief device of the present utility model, the staff can connect the connecting pipe 3 of the internal sound insulation unit 1 to the exhaust port of the pressure vessel through the external thread. Since the outer diameter of the internal sound insulation unit 1 is greater than that of the connecting pipe 3, such a design can make the internal sound insulation unit 1 form a limit and hold the box body 2; this design increases the sound insulation surface area and improves the sound insulation effect. The box body 2 can be fixed to the connecting pipe 3 through the bolt holes, ensuring the stability and sealing of the device;

[0029] The modular design of the device allows for quick assembly and disassembly, facilitating portability and movement. At the same time, the increased outer diameter of the sound insulation unit and the sealed connection of the box body 2 provide efficient noise reduction and improve the working environment.

[0030] Specifically: Screw the bolt holes of the box body 2 into the connecting pipe 3 and press against the boss formed by the internal sound insulation unit 1, and connect the connecting pipe 3 to the high-pressure vessel to complete the pressure relief work.

[0031] Furthermore, one side of the box body 2 opposite to the side provided with bolt holes is provided with a detachable cover plate 4. The design of using a detachable cover plate 4 on the side opposite to the bolt holes. The cover plate 4 is connected to the box body 2 through a hinge and can be quickly opened and closed through a lock or a quick clamp, facilitating inspection, maintenance of the internal sound insulation unit 1 or replacement of the sound insulation material.

[0032] Furthermore, the internal sound insulation unit 1 and the box body 2 are provided with uniform small holes; these small holes can effectively reduce the sound wave energy and achieve a sound insulation effect. At the same time, the distribution and size of the small holes have little impact on the gas flow during the pressure relief process.

[0033] Furthermore, a plurality of boxes 2 are provided; and each box 2 can be used independently, or they can be connected in series according to the actual working pressure and volume requirements to provide pressure relief solutions of different scales.

[0034] Furthermore, the plurality of boxes 2 are of different sizes, and the bolt holes are all sleeved on the connecting pipe 3, with the size increasing from inside to outside; all of its bolt holes can be sleeved on the connecting pipe 3, with the size increasing from inside to outside. The purpose of this design is to enable the device to adapt to pressure vessels of different sizes, and the best sound absorption and pressure relief effects can be achieved through the combination of boxes 2 of different sizes.

[0035] Furthermore, the sound absorption unit and the box 2 are filled with sound absorption cotton. This material can effectively absorb the noise generated during the pressure relief process, and the sound absorption cotton can be a flame-retardant material to ensure safety in use.

[0036] Furthermore, the connecting pipe 3 is provided with a bendable pipe fitting at one end for connecting to the pressure vessel. For example, a flexible metal hose or a jointed metal pipe is used, aiming to adapt to the position of the pressure vessel interface and reduce the need for precise alignment during installation.

[0037] Furthermore, the box 2 is provided with a fixing device 5 for connecting to the ground. The fixing device 5 can include support feet and anchor bolts to ensure that the entire device is stably placed on various working surfaces and prevent displacement caused by vibration or impact.

The pressure gauge can be directly installed on the surface of the box 2 and is designed to be shockproof, so as to monitor the internal pressure change in real time during the pressure relief process, understand whether the internal sound absorption cotton is blocked, and replace it in time.

[0039] Furthermore, a rubber sealing layer is provided at the top of the internal sound absorption unit 1 and the box 2. When the cover plate 4 is closed, this sealing layer can effectively block the internal noise from spreading to the outside and prevent dust and oil mist from leaking; and under the pressing action of the connecting pipe 3, the rubber sealing layers of each layer are squeezed to form a seal.
