Description

Technical Field

[0001] The invention relates to the discharge inspection of a ship air compressor and an air bottle, and in particular to an oil-gas separator for discharging compressed air of a ship. Background Art

[0002] Air compressors and air bottles on ships are key equipment to ensure the supply of compressed air, and they play a vital role in the daily operation of ships. However, when these devices are discharging, the gas discharged contains a high oil content, making the discharging process extremely difficult. This situation not only affects the normal operation of the air bottle, but also causes serious corrosion problems inside the air bottle. Since the air bottle is a pressure vessel, once rust occurs, the measured value of its wall thickness may exceed the safety standard, which in turn affects the storage and use efficiency of compressed air.

[0003] In order to solve this problem, crew members usually check the discharge of air compressors and air bottles regularly. However, during the discharge process, due to the presence of medium-pressure gas in the pipeline, manual discharge often encounters the situation where high-pressure gas splashes out oil and gas containing oil. This oil and gas not only pollutes the environment of the engine room, but also poses a threat to the safety of the crew. During the discharge process, oil and gas sometimes splash to every corner of the engine room, or even directly spray to the operating crew, which not only brings an additional burden to the cleaning work of the engine room, but also may cause potential harm to the health of the crew. Therefore, how to effectively solve the problem of oil content in the discharge of air compressors and air bottles and reduce pollution to the environment and personnel has become an important issue that needs to be solved in ship maintenance.

[0004] Aiming at the problems that it is difficult to separate oil and gas when the ship's compressed air is discharged from the air compressor and the air bottle, and the oil in the compressed air cannot be discharged in time, resulting in the oil and gas directly entering the discharge pipe and easily clogging the pipeline, the present invention designs a flexible oil and gas separator specially used for ship compressed air discharge, which solves the problems of difficult discharge and collection of air compressors and air bottles.

[0023] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0024] In order to fully understand the present invention, detailed steps and detailed structures will be proposed in the following description to illustrate the technical solution of the present invention. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0025] Reference Figure 1-2 As shown, the present invention provides an oil-gas separator for ship compressed air discharge, comprising a hollow separator cylinder 1, a discharge injection port 5 is provided on one side of the separator cylinder 1, and a discharge output port 6 is provided at the bottom of the separator cylinder 1 below the discharge injection port 5. The discharge injection port 5 is connected to the ship compressed air bottle through a discharge pipeline, and the discharge output port 6 is connected to the dirty oil tank through a discharge pipeline. The discharge injection port 5 and the discharge output port 6 are both provided with flanges 51 and 61 for connecting the discharge pipeline, and sealing gaskets are provided on the end faces of the flanges 51 and 61 to ensure the sealing of the connection.

[0026] A multi-layer orifice plate separator 4 is provided inside the separator cylinder 1, which is higher than the discharge injection port 5. The multi-layer orifice plate separator 4 is composed of multiple layers of stainless steel orifice plates stacked at intervals. The multiple layers of stainless steel orifice plates are fixedly connected by connecting pieces, and the upper and lower stainless steel orifice plates are both distributed with air holes staggered in the vertical direction. A discharge cover plate 2 is installed on the top of the separator cylinder 1, and a gas discharge gap 8 is provided between the discharge cover plate 2 and the upper end surface of the separator cylinder 1.

[0027] The present invention utilizes a traditional mesh separation filter to separate the oil and gas in the discharge pipeline, and discharges the filtered and separated oil into the dirty oil tank on the ship. It is designed to be a marine compressed air separator that can quickly separate the oil and gas and quickly discharge the oil. In this way, there is no need to trouble the crew on board to frequently observe and manually discharge the oil. It is convenient and flexible to install, and can also achieve the purpose of quickly separating the oil and gas.

[0028] The discharge cover plate 2 is a pressure cap that is buckled on the top of the separator cylinder 1. The discharge cover plate 2 is provided with a top plate and a side plate 21 arranged around the edge of the top plate. Four first angle steel brackets 7 are fixed at equal angles along the circumferential direction on the side wall of the separator cylinder 1. Four second angle steel brackets 3 corresponding to the positions of the first angle steel brackets 7 are fixed on the side plate 21. The second angle steel brackets 3 are fixedly connected with the first angle steel brackets 7 by screws to fix the discharge cover plate 2 on the separator cylinder 1. The first angle steel bracket 7 is provided with a waist-shaped hole in the vertical direction, and the height of the discharge cover plate 2 relative to the separator cylinder 1 can be appropriately adjusted, thereby adjusting the opening size of the gas discharge gap 8 to adapt to the release of different pressures. The lower side of the side plate 21 is higher than the top surface of the separator cylinder 1. With the help of the downward side plate 21 of the discharge cover plate 2, on the one hand, the gas is ejected downward (the dotted arrow in the figure is the flow direction of the gas, and the solid arrow is the flow direction of the oil), and at the same time, the gas is discharged along a circuitous path to avoid harm to the crew.

[0029] In an optional embodiment, the apertures of the stainless steel orifice plates of different layers are the same, so that the same specifications can be selected for each layer of stainless steel orifice plates, thereby reducing costs. In other optional embodiments, in the design of the separator cylinder 1, the apertures of the upper and lower layers of stainless steel orifice plates are designed to be gradually reduced from bottom to top. This design causes the resistance encountered by the oil as it flows upward through each layer of orifice plates to gradually increase. As the aperture gradually decreases, the resistance to the passage of the oil will become greater and greater, thereby effectively preventing the oil from spraying out of the separator cylinder 1. This design of gradually reducing the aperture not only improves the separation efficiency, but also ensures the safe operation of the entire system.

[0030] In an optional embodiment, each layer of stainless steel orifice plate is an arched plate with the center bulging upward. The design of this arched plate makes the stainless steel orifice plate have better strength and stability when bearing oil flow pressure, reduces the impact of high-pressure gas on the stainless steel orifice plate, and the arched structure can effectively disperse the pressure and reduce the risk of deformation and damage of the orifice plate. The center of the arched plate bulges upward, and it is also convenient for the oil droplets attached to the lower surface of the arched plate to slide naturally under the action of gravity, which is beneficial to prevent the oil from blocking the through holes of the orifice plate, and further improves the separation efficiency, improves the cleanliness of the stainless steel orifice plate, and reduces the number of cleaning times.

[0031] In some other optional embodiments, the surface of the stainless steel orifice plate can be coated with a layer of special oil-resistant and corrosion-resistant material. This material can be polytetrafluoroethylene PTFE or other coatings to ensure that the orifice plate maintains good oleophobicity during long-term use. The coating can not only improve the durability of the orifice plate, but also reduce the adhesion of oil to the orifice plate, thereby reducing maintenance costs and extending service life.

[0032] In practical applications, the height and diameter of the separator cylinder 1 can also be adjusted according to the characteristics of the oil-gas mixture. For example, for occasions with a large processing volume, the diameter of the cylinder can be increased to meet the larger flow requirements. By flexibly adjusting the size of the cylinder, the separation requirements under different working conditions can be met. In order to further optimize the separation effect, the hole spacing of the orifice plate and the distance between the orifice plates can also be adjusted.

[0033] A pad is provided in the middle of the edge of the upper and lower adjacent stainless steel orifice plates, and a gap is formed between the upper and lower stainless steel orifice plates through the pad. This gap design helps to further promote the separation of the oil-gas mixture. When the oil-water mixture passes through the orifice plate, due to the existence of the gap, the gas under pressure is more likely to pass through the gap between the upper and lower orifice plates, the holes of the stainless steel orifice plates, and finally be released through the gas discharge gap 8 (the gas flow direction is shown by the arrow direction).

[0034] In an optional embodiment, a convex ring 11 for supporting the multi-layer orifice plate separator 4 is provided on the inner wall of the separator cylinder 1, and the convex ring 11 is higher than the discharge injection port 5, and is used to install the multi-layer orifice plate separator 4 in the separator cylinder 1 higher than the discharge injection port 5. In addition, a threaded hole may be provided on the convex ring 11, and a bolt passes through the multi-layer orifice plate separator 4 and is threadedly matched with the threaded hole to fix the separator cylinder 1 in the separator cylinder 1, effectively preventing the high-pressure gas from impacting the multi-layer orifice plate separator 4 to cause shaking and noise.

[0035] In an optional embodiment, the separator cylinder 1 and the discharge cover plate 2 are made of galvanized carbon steel with good corrosion resistance, and an oleophobic coating is provided on the inner wall of the separator cylinder 1 and the discharge cover plate 2 to further improve the durability and separation efficiency of the separator. The oleophobic coating can effectively prevent oil droplets from accumulating on the inner wall, thereby reducing the residence time of the oil-gas mixture in the cylinder and accelerating the separation process. In addition, the oleophobic coating can also reduce the adhesion of oil droplets on the inner wall of the cylinder, making it easier to separate the oil droplets, further improving the separation efficiency.

[0036] The advantages of the present invention are:

[0037] 1. The use of an oil-gas separator can effectively reduce the oil content in the gas discharged during the discharge process of the air compressor and the air bottle, thereby reducing the rust problem inside the air bottle and ensuring the storage and use efficiency of compressed air.

[0038] 2. The oil-gas separator has a simple structure and is easy to operate. It can effectively reduce the danger of manual discharge and avoid the potential harm of oil and gas splashing to the cabin environment and crew health.

[0039] 3. The use of oil-gas separator can reduce the maintenance cost and time loss caused by oil and gas blocking the discharge pipeline, and improve the reliability of ship operation.

[0040] 4. The oil-gas separator of the present invention adopts multi-layer perforated plate separation technology, which can efficiently separate oil and gas and ensure the oil-gas separation effect. At the same time, it adopts modular design, which is convenient for installation, disassembly, and transshipment, and is flexible in operation, and is easy to install and use on ships.

[0041] 5. The separator cylinder and discharge cover are made of galvanized carbon steel and coated with oleophobic coating on the inner wall, which not only improves the corrosion resistance of the equipment but also facilitates cleaning and maintenance.

[0042] 6. Both the discharge injection port and the discharge output port are equipped with flanges and sealing gaskets to ensure the sealing of the discharge process, avoid oil and gas leakage, and ensure the safety of operation.

[0043] 7. By using the oil-gas separator of the present invention, ship maintenance personnel can more conveniently perform the discharge operation of the air compressor and the air bottle, thereby improving work efficiency and reducing maintenance costs.

[0044] In summary, the oil-gas separator of the present invention not only solves the problem of oil content in the discharge of compressed air from ships, but also improves the safety and efficiency of ship operation, and has significant practical value and economic benefits.
