Description

Technical Field

[0001] This application relates to the technical field of oil-gas separation systems, and in particular to an oil-gas separator tank for marine compressors. Background Technology

[0002] Currently, ship compressors generate a large amount of oil-containing gas during operation. If these gases are not effectively separated, they will not only pollute the compressed air, but also lead to a large consumption of lubricating oil and accelerated equipment wear. The shipbuilding industry has increasingly stringent requirements for compressed air quality, especially on ocean-going vessels and naval ships, where the cleanliness of compressed air is directly related to the reliability and service life of the equipment.

[0003] In related technologies, an oil-gas separator tank includes a tank body, an inlet pipe installed on the outer side of the tank body, an outlet pipe installed on the upper surface of the tank body, and a drain pipe on the lower surface. The inlet pipe is used to inject oil-containing gas discharged from the oil-gas compressor. Several baffles for changing the airflow direction are fixed in the vertical direction on the inner wall of the tank body. The baffles can separate oil and gas by changing the direction of the oil-containing gas flow and using the inertial force of the oil-containing gas to hit the baffle or the wall surface. The separated gas can be discharged from the outlet pipe after being purified by the vertical baffle. Under normal circumstances, oil will accumulate in the lower part of the tank body, and when it accumulates to a certain extent, the oil can be discharged through the drain pipe. Under normal circumstances, during the ship's operation, the oil-gas separator tank will shake with the vibration of the hull.

[0004] In the aforementioned technologies, the oil-gas separator tank shakes due to the ship's turbulence during navigation. When a large amount of oil accumulates in the tank after separation, the inertia generated by the shaking causes the oil to violently slosh and splash everywhere. More seriously, the splashed oil may flow back through pipes and be diverted to other equipment. Once the oil enters these devices, it can easily cause equipment failure or even damage, thus significantly negatively impacting the overall performance and operational reliability of the ship's equipment, indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide an oil-gas separator tank for marine compressors, which solves the problem in the above-mentioned related technologies that the oil-gas separator tank causes oil to slosh and splash during the ship's operation, and then flows to other equipment, causing other equipment to malfunction.

[0006] The oil-gas separator tank for a marine compressor provided in this application adopts the following technical solution:

[0007] A marine compressor oil-gas separator tank includes a tank body installed in a horizontal direction and a fixing plate for supporting the tank body. An air inlet pipe and a first air outlet pipe are respectively fixed on two opposite sides of the upper part of the tank body, and a sewage pipe is fixed on the lower part of the tank body.

[0008] Several staggered isolation plates are fixedly installed on the inner wall of the tank along the vertical direction, and several isolation holes are evenly opened on the isolation plates; a folding plate located below the opening of the first gas outlet pipe is fixedly installed on the inner wall of the tank, and the folding plate is used to prevent oily gas from being directly discharged from the first gas outlet pipe.

[0009] By adopting the above technical solutions, the horizontally installed tank, combined with a fixing plate, has a stable structure and can well adapt to the swaying environment during ship navigation. The air inlet pipe and the first air outlet pipe are set opposite each other, which facilitates the full flow of gas in the tank, extends the separation path, and improves the oil-gas separation effect. The staggered installation of the isolation plate with isolation holes can buffer the impact force, reduce the swaying amplitude, and make the oil evenly distributed to balance the pressure in the tank and avoid sudden changes in local pressure. The oil on the isolation plate slowly sinks and accumulates in the lower part of the tank. When it accumulates to a certain extent, it can be discharged through the drain pipe. The folding plate below the opening of the first air outlet pipe can effectively block the direct discharge of oily gas, ensuring that the discharged gas is cleaner and ensuring the stable operation of the ship's related equipment.

[0010] Optionally, a second vent pipe is fixedly provided on the upper surface of the tank, and a bent pipe is fixedly provided on the inner wall of the tank and is fixedly connected and communicated with the opening edge of the second vent pipe. The bent pipe is bent toward the upper surface of the tank.

[0011] By adopting the above technical solution, the bent pipe bends towards the upper surface of the tank and connects to the second vent pipe, which can change the gas discharge path. When the oily gas rises to the upper part of the tank, the bent structure can further buffer the airflow, allowing oil droplets and other impurities in the gas more time to separate from the gas, reducing the amount of oil discharged with the gas from the second vent pipe, and improving the oil-gas separation effect.

[0012] Optionally, an air outlet is provided on the outer side of the tank away from the fixed plate, and an inclined baffle is fixed on the inner wall of the tank below the air outlet. The inclined baffle is used to prevent unseparated oil and gas from being discharged directly from the air outlet.

[0013] By adopting the above technical solution, the inclined baffle is set below the gas outlet, which can effectively block insufficiently separated oil and gas. When the oil and gas mixture flows in the tank, the inclined baffle can change its flow direction, increase the residence time of oil and gas separation, and allow impurities such as oil droplets to have more opportunities to separate from the gas, preventing them from being discharged directly from the gas outlet, thus greatly improving the oil and gas separation effect.

[0014] Optionally, an extension plate is fixedly provided on the side edge of the fixing plate away from the tank body in a horizontal direction, and the extension plate is provided with a plurality of fixing through holes.

[0015] By adopting the above technical solution, the equipment can be firmly installed on the ship's hull and other supporting structures using fasteners such as bolts through the fixed through holes, thereby enhancing the firmness and stability of the installation and effectively resisting the swaying and vibration of the ship during navigation.

[0016] Optionally, a support block is provided below the tank body, the bottom surface of the support block is flush with the bottom surface of the fixing plate, and the upper surface of the support block is provided with an arc-shaped notch for the lower part of the tank body to be inserted and fixed.

[0017] By adopting the above technical solution, the bottom surface of the support block is flush with the bottom surface of the fixing plate, which can ensure that the entire oil-gas separator tank is placed stably, avoid shaking due to unevenness, and ensure stable operation of the equipment. The arc-shaped notch on the upper surface is adapted to the lower part of the tank. After being locked in place, it can effectively disperse the pressure brought by the tank and the internal medium, prevent the tank from being deformed or damaged due to excessive local stress, and extend the service life of the tank.

[0018] Optionally, the tank body is provided with a folding ladder on the outside. The folding ladder can be adjusted to a folded or unfolded state. A receiving groove is opened on the vertical outer side of the support block for the folding ladder to be placed in the folded state. The end of the folding ladder near the upper surface of the support block is rotatably connected to the inner wall of the receiving groove. When the folding ladder is in the unfolded state, it is used for users to climb and clean the upper part of the tank body.

[0019] By adopting the above technical solution, the folding ladder can be adjusted to a folded or unfolded state. When not in use, it can be folded and placed into the support block receiving slot, saving space, avoiding obstruction in the limited space on the ship, and reducing the risk of collision damage. When unfolded, it allows users to climb and clean the upper part of the tank, which is convenient for equipment maintenance and ensures its normal operation. The design of being rotatably connected to the support block makes the folding ladder flexible and convenient to operate, without the need for additional complicated installation and disassembly steps.

[0020] Optionally, the folding ladder includes a locking element, a fixed ladder, and a rotating ladder rotatably connected to one side of the fixed ladder. When the fixed ladder and the rotating ladder are rotated to a coaxial state, they are in an unfolded state. The locking element is used to limit and fix the fixed ladder and the rotating ladder in the coaxial state.

[0021] By adopting the above technical solution, after unfolding to the coaxial state, the locking component can quickly limit and fix it, ensuring the stability of the folding ladder, providing users with a safe and reliable climbing passage, and facilitating operations such as cleaning and maintenance of the upper part of the tank.

[0022] Optionally, the locking component includes a locking plate, a first fixing bolt, and a second fixing bolt. One end of the locking plate is detachably connected to the fixed ladder via the first fixing bolt, and the other end of the locking plate is detachably connected to the rotating ladder via the second fixing bolt.

[0023] By adopting the above technical solution, when the folding ladder is unfolded to a coaxial state, the locking plate can be quickly connected to the fixed ladder and the rotating ladder at both ends by bolts, respectively, to achieve stable positioning and ensure climbing safety. When not in use, the locking plate can be removed by unscrewing the bolts, making it convenient to fold and store the folding ladder and saving space.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The horizontally installed tank, equipped with a fixing plate, provides structural stability and adapts well to the swaying environment during ship navigation. The air inlet pipe and the first air outlet pipe are positioned opposite each other, facilitating full gas flow within the tank, extending the separation path, and improving oil-gas separation efficiency. The staggered installation of the baffle plate with isolation holes buffers impact forces, reduces swaying amplitude, and ensures even oil distribution to balance tank pressure and prevent sudden local pressure changes. As oil on the baffle plate slowly sinks, it accumulates at the bottom of the tank and can be discharged through the drain pipe when it reaches a certain level. The folding plate below the opening of the first air outlet pipe effectively prevents the direct discharge of oily gas, ensuring cleaner exhaust gas and guaranteeing the stable operation of ship equipment.

[0026] 2. The bottom surface of the support block is flush with the bottom surface of the fixing plate, which ensures that the entire oil-gas separator tank is placed stably and avoids shaking due to unevenness, thus ensuring stable operation of the equipment. The arc-shaped notch on the upper surface is adapted to the lower part of the tank. After being locked in place, it can effectively disperse the pressure brought by the tank and the internal medium, prevent the tank from being deformed or damaged due to excessive local stress, and extend the service life of the tank.

[0034] The present application will be further described in detail below with reference to all the accompanying drawings.

[0035] Example 1:

[0036] Reference Figure 1 and Figure 2 A marine compressor oil-gas separator tank includes a tank body 1 installed in a horizontal direction and a fixing plate 2 for supporting the tank body 1. The tank body is made of stainless steel. An air inlet pipe 11 and a first air outlet pipe 12 are integrally formed on both sides of the upper surface of the tank body 1. A sewage pipe 13 is integrally formed on the lower part of the tank body 1. Three staggered isolation plates 3 are fixed to the inner wall of the tank body 1 by welding in a vertical direction. A plurality of isolation holes 31 are evenly opened on the isolation plates 3.

[0037] During operation, oily gas flows into the spacious tank 1 through the inlet pipe 11, where the flow rate decreases. The oil sinks to the bottom of the tank due to inertia, and the gas impacts the baffle plate or tank wall due to inertial force, achieving efficient oil-gas separation. The separated gas is discharged through the first outlet pipe 12 and the outlet 14. If too much oil accumulates and sloshes, the isolation holes 31 on the isolation plate 3 can buffer the impact force, reduce the sloshing amplitude, and make the oil evenly distributed to balance the pressure inside the tank and avoid sudden changes in local pressure. Most of the oil accumulates in the lower part of the tank 1, and when it accumulates to a certain extent, it can be discharged through the drain pipe 13.

[0038] Reference Figure 1 Two fixing plates 2 are fixedly installed at the bottom of the tank body 1 by welding. Both fixing plates 2 are made of stainless steel. An extension plate 21 is integrally formed on the side edge of the fixing plate 2 away from the tank body 1 in the horizontal direction. Several fixing through holes 211 are evenly opened on the extension plate 21. The extension plate 21 can better support the structure of the tank body 1. After the bolts pass through the fixing through holes 211, the tank body 1 can be installed more stably on the ship.

[0039] Reference Figure 2 The upper surface of the tank body 1 is provided with an air outlet 14 and a second air outlet pipe 15 is fixed by welding. A folding plate 4 located below the opening of the first air outlet pipe 12 is fixed by welding on the inner wall of the tank body 1. The folding plate 4 is used to prevent oily gas from being directly discharged from the first air outlet pipe 12. An inclined baffle 5 located below the air outlet 14 is fixed by welding on the inner wall of the tank body 1. The inclined baffle 5 is used to prevent unseparated oily gas from being directly discharged from the air outlet 14.

[0040] A bent pipe 151 is fixed on the inner wall of the tank body 1, which is integrally formed with and connected to the opening edge of the second vent pipe 15. The bent pipe 151 bends towards the upper surface of the tank body 1. Since the bent pipe 151 is close to the upper surface of the oil inside the tank body 1, the bent pipe 151 can not only reduce the sloshing amplitude of the oil, but also reduce the gas flow resistance through the appropriate bending angle and curvature. This can better guide the separated gas to the second vent pipe 15 and reduce the turbulent flow of gas in the tank body 1.

[0041] The implementation principle of this application embodiment is as follows:

[0042] During operation, oily gas flows into the spacious tank 1 through the inlet pipe 11, reducing its flow rate. The oil sinks to the bottom of the tank due to inertia, while the gas impacts the baffle plate or tank wall, achieving efficient oil-gas separation. The separated gas is discharged through the first outlet pipe 12, the second outlet pipe 15, and the outlet 14. If excessive oil accumulates and sloshing occurs, the isolation holes 31 on the isolation plate 3 buffer the impact, reduce the sloshing amplitude, ensure even oil distribution, balance the tank pressure, and prevent sudden local pressure changes. If too much oil accumulates in the isolation holes 31, it will drip down to the bottom of the tank 1 and accumulate. Once a certain amount is reached, the oil can be discharged through the drain pipe 13.

[0043] The upper surface of the tank body 1 is provided with a second vent pipe 15 and matching structures such as a folding plate 4 and an inclined baffle 5, which can prevent direct discharge of oil and gas; and the bending pipe 151 can reduce the gas flow resistance by using appropriate bending angle and curvature, thereby better guiding the separated gas to the second vent pipe 15; and the fixing through hole 211 on the extension plate 21 of the fixing plate 2 facilitates the stable installation of the tank body 1, ensuring efficient oil and gas separation and stable operation.

[0044] Example 2:

[0045] Reference Figure 3 The difference between this embodiment and Embodiment 1 is that a support block 6 is fixed below the tank body 1, and the support block 6 is made of stainless steel; the bottom surface of the support block 6 is flush with the bottom surface of the fixing plate 2, and the upper surface of the support block 6 is provided with an arc-shaped notch 61 for the lower part of the tank body 1 to be inserted and fixed.

[0046] Reference Figure 3 and Figure 4 The tank body 1 is provided with a folding ladder 7 on its exterior. The folding ladder 7 can be adjusted to a folded or unfolded state. The support block 6 has a receiving groove 62 on its vertical outer surface for the folding ladder 7 to be placed in the folded state. When the folding ladder 7 is in the unfolded state, it is used for users to climb and clean the upper part of the tank body 1.

[0047] When cleaning operations are required on the surface of tank 1, the staff can first adjust the folding ladder 7 to the unfolded state and then place it at an angle on the ground; then, the staff can climb up the ladder and use a high-pressure water gun and cleaning brush to thoroughly clean the surface of tank 1.

[0048] Reference Figure 4 and Figure 5 The folding ladder 7 includes a locking member 71, a fixed ladder 72, and a rotating ladder 73 rotatably connected to one side of the fixed ladder 72. When the fixed ladder 72 and the rotating ladder 73 are rotated to the coaxial state, they are in the unfolded state. At this time, the length of the folding ladder 7 reaches its maximum, making it convenient for users to climb.

[0049] The end of the fixed ladder 72 furthest from the rotating ladder 73 is rotatably connected to the inner wall of the receiving groove 62 via a pivot 74; this connection method facilitates the flexible storage and unfolding of the fixed ladder 72, and the operation is simple and quick.

[0050] When the fixed ladder 72 and the rotating ladder 73 are rotated to a coaxial state, the locking member 71 can quickly limit and fix them, ensuring that the folding ladder 7 remains stable in the unfolded state and will not shake or fold during use.

[0051] Reference Figure 5 The locking component 71 includes a locking plate 711, a first fixing bolt 712 and a second fixing bolt 713. One end of the locking plate 711 is detachably connected to the fixed ladder 72 via the first fixing bolt 712, and the other end of the locking plate 711 is detachably connected to the rotating ladder 73 via the second fixing bolt 713.

[0052] The locking plate 711 has a first through hole 7111 and a second through hole 7112 at its two ends. The fixed ladder 72 has a first screw hole 721 on its outer side near the rotating ladder 73. The rotating ladder 73 has a second screw hole 731 on its outer side near the fixed ladder 72. The first fixing bolt 712 can be screwed into the first screw hole 721 after passing through the first through hole 7111. Similarly, the second fixing bolt 713 can be screwed into the second screw hole 731 after passing through the second through hole 7112.

[0053] The surfaces of the first fixing bolt 712 and the second fixing bolt 713 are both treated with rust prevention, and have good wear resistance and corrosion resistance. At the same time, in order to facilitate the use of operators during installation and disassembly, the first fixing bolt 712 and the second fixing bolt 713 are both wing bolts.

[0054] The implementation principle of this application embodiment is as follows:

[0055] On the supporting structure of the tank body 1, a support block 6 is welded to the bottom of the tank body 1. Its bottom surface is flush with the fixed plate 2, and its upper surface has an arc-shaped notch 61 that fits the lower part of the tank body 1. It can firmly hold the tank body 1, effectively disperse pressure, and ensure stable operation of the equipment. The tank body 1 is equipped with a foldable ladder 7. The side of the support block 6 is provided with a receiving groove 62. The foldable ladder 7 can be stored in it after folding, saving space and avoiding interference.

[0056] The folding ladder 7 consists of a fixed ladder 72, a rotating ladder 73, and a locking component 71. The rotating ladder 73 and the fixed ladder 72 are rotated to the same axis to unfold, reaching their maximum length, which facilitates users to climb the upper part of the tank 1 for cleaning. The locking component 71 connects and fixes the locking plate 711 to the fixed ladder 72 and the rotating ladder 73 through the first and second fixing bolts 713 to ensure the stability of the unfolded state. The bolts are rust-proofed and have a butterfly design, which makes them easy to disassemble and assemble by hand, improving the stability of equipment operation and ease of use.
