[0002] As a vital energy production base, hydropower stations have complex internal structures, with pressure vessels being essential, critical equipment. During routine operations and maintenance, these pressure vessels require regular inspections to ensure their safety and reliability. These vessels are filled with high-pressure gas, which often contains a certain amount of oil mist from the compressor's lubricating oil and the hydraulic oil in the speed control system.

[0003] When these pressure vessels are depressurized, the mixed gas inside is directly discharged into the surrounding environment, causing a large amount of oil mist to enter the air in the area. This oil mist is potentially harmful to human health. Long-term inhalation can cause respiratory problems and even affect the physical and mental health of workers. In addition, the spread of oil mist can pollute the surrounding environment and affect the ecological balance.

[0004] At the same time, long-term exposure of peripheral equipment to oil mist can cause a large amount of oil to adhere to the equipment surface. This not only affects the appearance of the equipment, but more importantly, the accumulation of oil can reduce the equipment's heat dissipation efficiency and increase the failure rate, thereby posing a significant risk to the safe and stable operation of the hydropower station. Oil pollution can also accelerate equipment corrosion, shorten its service life, and increase maintenance costs. Utility Model Content

[0021] The present invention will be described in detail below with reference to the accompanying drawings.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is 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 invention and are not intended to limit the present invention.

[0023] A decompression oil mist absorption device, such as Figure 1 As shown, it includes an outer ring plate 2, an inner ring plate 1 is provided inside the outer ring plate 2, and a number of dense holes are provided on the outer ring plate 2 and the inner ring plate 1, and an oil mist absorbing material 5 is provided between the outer ring plate 2 and the inner ring plate 1; the upper part of the inner ring plate 1 and the outer ring plate 2 are jointly covered with an upper cover 3, and the middle part of the upper cover 3 is provided with a preset interface 31, and the preset interface 31 is connected to the interior of the inner ring plate 1; the lower part of the inner ring plate 1 and the outer ring plate 2 are also jointly covered with a lower cover 4.

[0024] Specifically, the design of the outer ring plate 2 and inner ring plate 1 in this solution makes the entire device compact and easy to install in limited spaces, making it particularly suitable for space-constrained industrial environments. The outer ring plate 2 and inner ring plate 1 are equipped with fine-mesh holes. When the oil mist passes through these holes, the airflow is dispersed into many small streams. This dispersion effect ensures that the oil mist does not pass through as a concentrated stream, but rather contacts the absorbent material in the form of multiple small streams. Furthermore, the fine-mesh holes can be designed with an appropriate shape, size, or number depending on the application and the filter medium. The oil mist absorbent material 5 is located between the outer ring plate 2 and inner ring plate 1, forming a filtration system that thoroughly separates and absorbs oil droplets from the oil mist. The design of the upper cover 3 and lower cover 4 ensures a good seal throughout the entire device, preventing oil mist from leaking into the external environment. It also allows for easy replacement and maintenance of the oil mist absorbent material 5, ensuring long-term stable operation of the device. The upper cover 3 and lower cover 4 are fixedly connected to the outer ring plate 2 to prevent it from falling off during the absorption process. Furthermore, the upper cover 3 and the lower cover 4 can be connected to the outer ring plate 2 in a detachable or non-detachable manner, such as interference fit, connection structure, welding, etc. The pre-set interface 31 is connected to the interior of the inner ring plate 1, and the airflow can be directed when the pressure is released, ensuring that the oil mist can fully contact the absorption material, thereby improving the absorption efficiency. This structural design can adapt to the discharge of oil mist with different flow rates and concentrations. By adjusting the size and number of the close-mesh holes and replacing the absorption materials with different properties, it can adapt to various working conditions. Furthermore, the oil mist absorption material 5 can be selected from, but does not include: glass fiber cotton, plant fiber, polypropylene, polyurethane foam, alkyl vinyl polymer, etc.

[0025] As another specific embodiment, the inner ring plate 1 and / or the outer ring plate 2 are in the shape of a ring. The ring design allows the dense mesh holes to be evenly distributed across the entire ring surface, ensuring that the oil mist can evenly contact the absorbent material when entering the absorption device, thereby improving absorption efficiency. At the same time, the circular design has no right angles or sharp corners, which can reduce dead corners in the flow of oil mist, reduce the risk of oil mist accumulation and non-absorption, and make the absorbent material easier to install and replace. In addition to the above embodiments, the inner and outer ring plates 2 and the filter material chambers they form can also be set to different shapes according to the actual space conditions of the application.

[0026] As another specific embodiment, the inner ring plate 1 and the outer ring plate 2 are coaxial. The coaxial design ensures structural symmetry, helps to evenly distribute the oil mist absorbing material 5, ensures the same oil mist absorption effect at each circumferential position, and simplifies the manufacturing process.

[0027] As another specific embodiment, the upper cover 3 and / or lower cover 4 are provided with retaining steps on the facing sides thereof, and the inner ring plate 1 is positioned within the retaining steps. The retaining steps provide precise positioning for the inner ring plate 1, ensuring its correct position within the device and thus maintaining the stability of the overall structure. The design is relatively simple, requiring no complex mating structures, and is therefore easy to manufacture and install.

[0028] In contrast to the previous embodiment, in another specific embodiment, a first annular groove is provided on the facing sides of the upper cover 3 and / or the lower cover 4. The inner diameter of the first annular groove is no larger than the inner diameter of the inner ring plate 1, and the outer diameter of the first annular groove is no smaller than the outer diameter of the inner ring plate 1. The first annular groove can form a tighter sealing interface with the inner ring plate 1, effectively preventing oil mist leakage and improving the cleanliness of the exhaust gas.

[0029] As another specific embodiment, the outer edges of the upper cover 3 and / or lower cover 4 have folded edges on the facing sides. These folded edges serve as guides during assembly, simplifying the assembly process between the cover and the outer ring plate 2. Furthermore, they provide close contact with the outer ring plate 2, helping to improve sealing performance and prevent oil mist leakage.

[0030] In contrast to the previous embodiment, in another specific embodiment, a second annular groove is provided on the facing sides of the upper cover 3 and / or the lower cover 4. The inner diameter of the second annular groove is no larger than the inner diameter of the outer ring plate 2, and the outer diameter of the second annular groove is no smaller than the outer diameter of the outer ring plate 2. The second annular groove can also provide precise positioning for the outer ring plate 2, ensuring that the outer ring plate 2 is in the correct position and maintaining the stability of the device.

[0031] When the inner ring plate is not circular, it must be able to be placed in the limiting step or the first annular groove. Preferably, the inner ring plate has the same shape as the limiting step or the first annular groove. When the outer ring plate is not circular, it must be able to be placed in the folded edge or the second annular groove. Preferably, the outer ring plate has the same shape as the folded edge or the second annular groove.

[0032] A pressure vessel that facilitates the absorption of decompression oil mist comprises a pressure vessel body, a decompression pipeline provided on the pressure vessel body, and a decompression oil mist absorption device as described above disposed at the end of the decompression pipeline. The decompression oil mist absorption device effectively reduces the emission of oil and gas into the external environment during the decompression process, thereby reducing atmospheric pollution, complying with environmental protection requirements, lowering the risk of fire and explosion in the workplace, and ensuring operator safety. Furthermore, the absorption of oil mist prevents oil contamination of the decompression pipeline and the pressure vessel body, ensuring the normal operation and performance of the equipment.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The present invention extends to any new features or any new combinations disclosed in this specification, and any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
