Description

Technical Field

[0001] This application belongs to the field of marine engineering technology, and further relates to marine skid equipment testing technology, specifically providing an auxiliary device and method for testing the air pressure of containers used in marine skids. Background Technology

[0002] Pressure vessels on marine skids are an essential component of the platform, responsible for storing and transporting oil. To ensure safety and reduce risks, the strength, sealing, and safety of the pressure vessels must be verified during manufacturing. Pressure testing is a crucial step in this process. After the pressure test is completed, the high-pressure gas inside the pressure vessel must be released into the external environment. During this process, the rapid expansion and pressure release of the gas will generate high-frequency noise (reaching 100-200 dB) at the gas outlet of the pressure vessel. This high-frequency noise not only affects the working environment of the marine skid but also poses a threat to the health and safety of the pressure testing personnel.

[0003] In addition, high-pressure gas (or compressed gas) is generally supplied by a compressor. Due to the complexity of the marine environment, the compressed gas may contain impurities such as water and particulate matter before entering the pressure vessel. If it is not treated in advance, the compressed gas containing impurities will cause a certain degree of damage to the pressure vessel. Therefore, in order to avoid defects such as corrosion and blockage to the vessel, it is necessary to clean the pressure vessel thoroughly after pressurization. Summary of the Invention

[0022] <First Embodiment> This embodiment provides an auxiliary device for detecting the air pressure of a container used in marine skids. Figure 1 A schematic diagram of the layout of the air pressure detection auxiliary equipment is shown. Figure 2 right Figure 1 The circle I in the image is enlarged. Figure 3 This is a structural schematic diagram of the auxiliary device from another perspective. Figure 4 This is a side view of the auxiliary device. (Example) Figures 1 to 4 As shown, the auxiliary device is installed on the base plate 1 of the marine skid. During the process of pressure detection of the pressure vessel 2 on the marine skid, the auxiliary device is used to perform pressure stabilization and filtration of the compressed gas injected into the pressure vessel 2, and to perform noise reduction of the high-pressure gas discharged from the pressure vessel 2.

[0023] Specifically, refer to Figures 1 to 4 The auxiliary equipment includes a pressure stabilizing device 3, a filtering device 4, and a silencer 5. The air inlet of the pressure stabilizing device 3 is connected to the air outlet of the compressor (not shown in the figure) to stabilize the pressure of the compressed gas input from the compressor. The filtering device 4 is connected to the air outlet of the pressure stabilizing device 3 and the air inlet of the pressure vessel 2 on the marine skid to filter and dry the compressed gas flowing in from the pressure stabilizing device 3 and to allow the filtered compressed gas to flow into the pressure vessel 2. The silencer 5 is connected to the air outlet of the pressure vessel 2 and is connected to the external atmospheric environment to silence the gas flowing out from the pressure vessel 2.

[0024] Further, refer to Figures 1 to 4The core component of the pressure stabilizing device 3 is a pressure stabilizing tank 31 with a large volume. The pressure stabilizing tank 31 is preferably made of a high-pressure resistant metal material and can be fixed to the base plate 1 of the marine skid by a bracket, base or other optional fixing method. Preferably, a first valve 34 is provided at the connection between the pressure stabilizing tank 31 and the compressor outlet to control the opening or closing of the gas passage between the compressor and the pressure stabilizing tank 31, or to adjust the airflow velocity from the compressor into the pressure stabilizing tank 31. When the first valve 34 is open, compressed air enters the pressure stabilizing tank 31 through a thinner pipe. Since the cross-sectional area of ​​the air inlet pipe is much smaller than that of the pressure stabilizing tank 31, the cross-sectional area through which the gas flows increases sharply, thereby greatly reducing the flow velocity of the high-pressure gas and effectively achieving the pressure stabilizing effect.

[0025] It should be noted that this embodiment does not limit whether the pressure stabilizing device 3 includes the first valve 34. In some optional implementations, this valve that controls the gas passage between the compressor and the pressure stabilizing device 3 can also be set at the outlet of the compressor.

[0026] To more precisely control the pressure of the compressed gas flowing from the pressure stabilizing tank 31 to the pressure vessel 2, such as... Figures 1 to 4 As shown, in some preferred embodiments, a pressure measuring module 32 is also installed on the pressure stabilizing tank 31. The pressure measuring module 32 may be a digital or analog pressure gauge, used to measure the pressure inside the pressure stabilizing tank 31 in real time.

[0027] Furthermore, as compressed gas continuously enters the pressure stabilizing tank 31, the gas flow rate decreases and the gas pressure gradually increases to a stable high-pressure state. Therefore, the moisture contained in the gas in the pressure stabilizing tank 31 will continuously condense and settle to the bottom of the pressure stabilizing tank 31. For this reason, in some preferred embodiments, such as... Figure 2 , Figure 4 As shown, the bottom of the pressure stabilizing tank 31 is constructed as a concave shape with a low center and a high periphery to facilitate the collection of condensed liquid. Furthermore, a liquid discharge valve 33 is provided at the bottom of the pressure stabilizing tank 31. The liquid discharge valve 33 can discharge the liquid accumulated at the bottom of the pressure stabilizing tank 31 out of the tank by discharging it at regular or irregular intervals, thereby achieving the effect of initially removing moisture from the compressed gas while stabilizing the pressure of the compressed gas.

[0028] The compressed gas, after being regulated, enters the filter 4 through the pipe 35 connecting the outlet of the pressure regulated device 3 and the inlet of the filter 4, so as to further filter out various impurities contained therein.

[0029] Figure 5 The filter device 4 is shown in cross-section, and the cut line is... Figure 4 Middle AA line, for reference Figures 1 to 5The filter device 4 includes a filter housing 41 and an adsorption filter material 42 disposed inside the filter housing 41.

[0030] Specifically, the filter housing 41 can be made of materials with good strength and corrosion resistance (such as corrosion-resistant metal materials such as stainless steel, or composite materials such as carbon fiber) known to those skilled in the art. It is fixed to the substrate 1 of the marine skid by means of brackets, bases, etc. The adsorption filter material 42 can be honeycomb silicone blocks, which are filled in the filter housing 41. Utilizing the porous structure of silicone, it can efficiently adsorb residual moisture in compressed gas, as well as particulate matter larger than 0.5 micrometers.

[0031] The air outlet of the filter housing 41 is connected to the air inlet of the pressure vessel 2, for reference. Figures 1 to 4 Multiple air ports are provided on the tank body 21 of pressure vessel 2, for example... Figure 1 The first air port 221, the second air port 222, and the third air port 223 in the pressure vessel can be selected as appropriate as an air inlet, air outlet, or a bidirectional air port that can both inlet and outlet, depending on the specific application requirements during the use and testing of the pressure vessel. For example, in Figures 1 to 4 In the process, the air outlet of the filter box 41 is connected to the first air port 221 of the pressure vessel 2 via a flexible hose 23 (symbolically represented by a curve), indicating that the first air port 221 will serve as the air inlet of the pressure vessel during air pressure detection. In some other optional implementations, other air ports can also be selected as the air inlet. Therefore, in this application, there is no limitation on the air inlet or outlet of the pressure vessel.

[0032] Furthermore, in some preferred implementations, such as Figure 3 and Figure 5 As shown, a second valve 43 is also provided at the air outlet of the filter housing 41 to control the air supply to the pressure vessel 2 or to stop the air supply to the pressure vessel 2. Of course, similar to the first valve 34, this valve that controls whether to supply air to the pressure vessel 2 can also be set at the air inlet of the pressure vessel 2.

[0033] In this embodiment, the auxiliary equipment, through the mutually cooperating pressure stabilizing device 3 and filter device 4, can effectively stabilize the gas pressure entering the pressure vessel 2 and ensure the dryness and cleanliness of the compressed gas entering the pressure vessel 2.

[0034] Figure 6 The left side shows the internal structure of the silencing device 5 in this embodiment, and the right side shows a magnified view of a portion of the structure of circle II. For clarity, the front box structure is omitted.

[0035] refer to Figures 1 to 4 as well as Figure 6The silencing device 5 includes a silencing housing 51 and silencing material disposed inside the silencing housing 51. The silencing housing 51 can be formed by several vertical and horizontal baffles and fixed to the base plate 1 of the marine skid by a bracket, base, or other structure. Preferably, these baffles can be made of materials with certain strength and good sound-absorbing performance, such as polymer materials like polypropylene (PP) and polyvinyl chloride (PVC), or corrosion-resistant metal materials like stainless steel. To enhance the noise reduction effect, a sound-absorbing layer such as sponge can also be applied to its inner surface.

[0036] The air inlet of the silencer 51 is connected to the air outlet of the pressure vessel 2, and several exhaust holes 511 are opened on its top. The sound-absorbing material is placed inside the silencer 51. After the pressure of the pressure vessel 2 is tested, the gas flows out from the air outlet of the pressure vessel 2 and enters the silencer 51. After being silenced by the sound-absorbing material, it is discharged into the outside atmosphere through the exhaust holes 511 of the silencer 51.

[0037] like Figure 5 As shown, in this embodiment, the sound-absorbing material includes multiple layers of spaced sound-absorbing plates 52. The sound-absorbing plates 52 can be made of silicone sheets. First, the silicone sheets are cut according to the internal cross-sectional shape of the sound-absorbing box 51. Then, multiple through holes 521 are opened on them to form a honeycomb-shaped sound-absorbing structure. Finally, multiple sound-absorbing plates 52 are fixedly installed inside the sound-absorbing box 51 at certain intervals, thus completing the installation of the sound-absorbing material. During the exhaust process of the gas in the pressure vessel 2, the high-pressure gas flowing out of the pressure vessel 2 passes through the honeycomb-shaped sound-absorbing structure of the multiple layers of sound-absorbing plates in sequence, which can effectively reduce the noise of the exhaust gas.

[0038] See Figures 1 to 4 In some preferred embodiments of this example, a turbine fan 6 is also provided between the outlet of the pressure vessel 2 and the inlet of the silencer 5 to reduce the pressure and speed of the gas flowing out of the pressure vessel 2.

[0039] Specifically, such as Figure 2 As shown, the air inlet of the turbine fan 6 is connected to the second air port 222 of the pressure vessel 2 (in this embodiment, the second air port 222 serves as the air outlet of the pressure vessel 2) via a hose 23, and the air outlet is connected to the air inlet of the silencer 5 via a pipe 64. The turbine fan 6 is composed of a volute 61, a first impeller (not shown in the figure) disposed inside the volute 61, and a second impeller 62 disposed outside the volute 61. Both the first impeller and the second impeller 62 include a number of blades distributed circumferentially. Their rotation axes are fixedly connected coaxially and can be rotatably connected to the volute 61 via bearings.

[0040] When the pressure vessel 2 is venting, the gas flowing out of its interior passes through the volute 61 of the turbine fan 6, which drives the first impeller inside to rotate and drives the second impeller 62 outside to rotate synchronously. This converts the energy of the gas flow into the kinetic energy of the impeller rotation. Through this energy conversion process, the gas pressure and flow rate entering the silencer box 51 can be effectively reduced, thereby further improving the noise reduction effect on the gas discharged from the pressure vessel 2.

[0041] Preferably, a third valve 63 is provided at the air inlet of the turbine fan 6 to control the exhaust operation from the pressure vessel 2, or to stop the exhaust from the pressure vessel 2. Similarly, similar to the first valve 34, this valve controlling whether to exhaust from the pressure vessel 2 can also be provided at the air outlet of the pressure vessel 2.

[0042] The auxiliary equipment for pressure testing of containers on marine skids provided in this embodiment, through the reasonable setting of gas pressure stabilization, filtration and noise reduction structures, can achieve a high-purity, constant-pressure supply of compressed gas when performing pressure testing on pressure containers on marine skids, and effectively reduce the noise of gas discharged from pressure containers after the test, avoiding the adverse effects of noise on the marine skid environment and personnel.

[0043] <Second Embodiment> This embodiment provides an auxiliary device for detecting the air pressure of a container used in marine skids. Figure 7 The left side shows the deployment of this auxiliary equipment on the marine skid. Figure 7 The right side shows a magnified view of circle III; Figure 8 , Figure 9 , Figure 10 These are the side view, top view, and front view of the auxiliary equipment, respectively.

[0044] The main difference between the auxiliary equipment provided in this embodiment and the first embodiment is that the filter device 4 and the silencer device 5 in the first embodiment are combined into one. That is, in this embodiment, the filter device and the silencer device are constructed as a filter and silencer part 7.

[0045] Figure 11 The internal structure of the filter silencer 7 is further shown (the front box structure is hidden). Figure 12 This is a top view of the filter silencer 7. Figure 13 The left side shows the front view of the filter silencing unit 7, and the right side shows the side view of the filter silencing unit 7. In all the above figures, to clearly show the internal details, some vertical baffles on the outside of the enclosure have been omitted, and structures that cannot be directly seen are depicted with dashed lines.

[0046] refer to Figures 11 to 13In this embodiment, the filter and noise reduction section 7 has a box-shaped outer wall 76 formed by several horizontal baffles and vertical baffles, and inside it, an internal box structure is further separated.

[0047] Specifically, such as Figure 11 As shown, the first housing 71 is formed by the horizontal baffle 771, the vertical baffle 772, and the outer wall in contact with these baffles. The first housing 71 is provided with a filter and noise reduction structure, which combines the adsorption and filtering materials and the noise reduction material in the first embodiment. That is, during the inflation process of the pressure vessel 2, the filter and noise reduction structure adsorbs and filters the moisture and impurities in the compressed gas, and during the exhaust process of the pressure vessel 2, the filter and noise reduction structure reduces noise.

[0048] Preferably, the filtration and noise reduction structure comprises a plurality of filtration and noise reduction plates 711 spaced apart inside the first housing 71, each filtration and noise reduction plate having a plurality of filtration and noise reduction holes 7110 arranged in a honeycomb pattern. The material, manufacturing method, and arrangement of the filtration and noise reduction plates 711 can be found in the description of the noise reduction plate 52 in the first embodiment. Furthermore, the material, manufacturing method, and arrangement of the housing structure of the filtration and noise reduction section 7 can be found in the description of the filtration housing 41 and the noise reduction housing 51 in the first embodiment, and will not be repeated here.

[0049] Since the first chamber 71 integrates the dual functions of filtration and noise reduction, the gas exhibits different entry and exit methods and flow directions inside the pressure vessel 2 at different stages of the gas pressure test. Therefore, the air ports connecting the first chamber 71 to the outside are all bidirectional air ports.

[0050] Specifically, refer to Figures 11 to 13 Two bidirectional air ports are provided on the first housing 71, namely the first bidirectional air port 73 and the second bidirectional air port 74. The first bidirectional air port 73 is used to allow compressed gas that has been regulated by the pressure stabilizing device 3 to flow into the first housing 71, and to allow gas that has been silenced by the filter and silencer structure to flow out of the first housing 71. The second bidirectional air port 74 is used to allow compressed gas that has been adsorbed and filtered by the filter and silencer structure to flow into the pressure vessel 2, and to allow gas flowing out of the pressure vessel 2 to flow into the first housing 71.

[0051] Preferably, to ensure that the gas can flow in different directions at different stages of the pressure test, a gas reversing valve 81 is provided between the outlet of the pressure stabilizing device 3 and the first bidirectional air port 73 of the first housing 71. The gas reversing valve 81 has three valve ports: a first valve port 811, a second valve port 812, and a third valve port 813. The first valve port 811 is connected to the outlet of the pressure stabilizing device 3 through a pipe 35, and the second valve port is connected to the first bidirectional air port 73. By manually or automatically switching the gas flow direction inside the reversing valve 81, when the pressure vessel is being pressurized, the gas can be controlled to flow from the first valve port 811 to the second valve port 812 and then into the first housing 71 through the first bidirectional air port 73; when the pressure vessel is being vented, the gas flowing out of the first bidirectional air port 73 of the first housing 71 can be controlled to flow from the second valve port 812 to the third valve port 813.

[0052] Preferably, the filter and silencer section 7 further includes a second housing 72, such as Figures 11 to 13 As shown, the second housing 72 is positioned above the first housing 71. It is also formed by a horizontal baffle 771, a vertical baffle 772, and the outer wall of the filter and silencing section 7. The air inlet 75 of the second housing 72 is connected to the third valve port 813 of the reversing valve 81. Several exhaust holes 721 are also provided on its top. Using the second housing 72, the gas after being silenced by the first housing 71 can be further expanded and depressurized, thereby achieving a better noise reduction effect.

[0053] In this embodiment, preferably, a turbine fan 6 is also provided to depressurize and slow down the gas discharged from the pressure vessel 2.

[0054] In this embodiment, as shown in the first embodiment, the gas can be introduced into the pressure vessel 2 from different gas ports. In addition, preferably, in order to further simplify the pipeline structure, the second bidirectional gas port 74 can be connected to the bidirectional gas port of the pressure vessel through the parallel inlet pipeline 84 and the exhaust pipeline 85.

[0055] Specifically, refer to Figures 7 to 10 One end of the intake pipe 84 and the exhaust pipe 85 are merged into the second bidirectional air port 74 through a three-way structure, and the other end is also merged to form a three-way structure and connected to the first air port 221 of the pressure vessel 2 through a hose 23. At this time, the first air port 221 serves as a bidirectional air port and is used as an intake or exhaust port at different stages of the air pressure test. In addition, a first one-way valve 82 is provided on the intake pipe 84 and a second one-way valve 83 is provided on the exhaust pipe 85 to control the gas flow during the inflation and deflation processes, respectively (in fact, the first one-way valve 82 and the second one-way valve 83 have the same function as the second valve 43 and the third valve 63 in the first embodiment, respectively). At the same time, the turbine fan 6 is installed on the exhaust pipe 85.

[0056] Figure 14 This further illustrates the gas flow direction during intake and exhaust in this implementation. Figure 15 and Figure 16 The diagrams show the flow of gas in the reversing valve 81 and the filter / silencing unit 7 during the inflation and deflation operations, respectively. In the diagrams above, the red line represents the gas flow direction during the inflation operation, and the blue line represents the gas flow direction during the deflation operation.

[0057] As can be seen from the above figures, during the air inflation phase, compressed gas enters the first housing 71 from the lower first bidirectional air port 73 and moves upward. After being adsorbed and filtered by the multi-layer filter and silencer plate 711, it flows out from the upper second bidirectional air port 74. Utilizing the porous structure of the filter and silencer plate 711, residual moisture and particles larger than 0.5 microns in the air can be effectively removed, achieving the purpose of delivering dry, clean, and pressure-stable compressed gas to the pressure vessel 2. In addition, placing the first bidirectional air port below the second bidirectional air port 74 allows impurities in the compressed gas to have their kinetic energy reduced due to gravity during upward movement, making them easier to be adsorbed by the filter and silencer plate 711. During the exhaust phase, the gas discharged from the pressure vessel 2 flows into the first housing 71 from the upper second bidirectional air port 74 and moves downward. After being silenced by the multi-layer filter and silencer plate 711, it flows out from the lower first bidirectional air port 73, and then continues upward into the second housing 72 through the reversing valve 81. After further diffusion and deceleration, it is finally discharged into the external atmosphere through the exhaust port 721.

[0058] By utilizing the mutually cooperating filter silencer and reversing valve, the same filter silencer structure is used in the same housing to achieve both filtration and noise reduction effects, effectively reducing the complexity of auxiliary equipment and the limited space occupied on the marine skid. Furthermore, by utilizing the vertical positional relationship between the first bidirectional air port 73 and the second bidirectional air port 74, the impurities contained in the compressed gas can be effectively degraded rapidly under their own gravity during the filtration stage, thereby further improving the filtration effect.

[0059] Figure 17 The structure of the filter silencing plate 711 is shown. Considering that the filter silencing structure composed of the multi-layer filter silencing plate 711 plays different roles in different stages of air pressure testing, its structure can be further optimized.

[0060] Specifically, in some preferred embodiments, such as Figure 18 , Figure 19 As shown in the cross-sectional view, the aperture of the filter noise reduction holes 7110 on the upper surface of each filter noise reduction plate 711 is... Smaller than its aperture on the lower surface The diameter of the entire filter silencer hole 7110 gradually decreases from bottom to top, presenting a frustum-shaped structure. By using this type of filter silencer hole 7110, the adsorption and filtration effect can be further improved by using the inclined cone surface during the air pumping process, and the effect of layer-by-layer diffusion pressure reduction and noise reduction can be formed during the exhaust process.

[0061] Furthermore, in some other preferred embodiments, the aperture of the filter silencing holes on each filter silencing plate may be larger than the aperture of the filter silencing holes on the filter silencing plate above it. Specifically, for example... Figure 20 As shown, the aperture of the filter noise reduction hole 7110-1 in the bottommost filter noise reduction plate 711-1 is... The filter noise reduction holes 7110-2 of the filter noise reduction plate 711-2 have a diameter of [missing information]. The filter silencer plate 711-3 located at the top has filter silencer holes 7110-3 with a diameter of [missing information]. ,and Therefore, it is also possible to achieve [something related to] ... Figure 18 , Figure 19 The implementation method is similar to the dual effect.

[0062] It should be noted that when the filter silencer uses, such as Figure 20 When using the structure shown, the density of the filter and noise reduction holes in each layer can be increased layer by layer to ensure that the overall airflow cross-section of each layer is approximately equal. Alternatively, it is also possible to... Figure 18 and Figure 20 The implementation method combines the following: the aperture between each layer gradually decreases from bottom to top, while the aperture of each layer also gradually decreases from bottom to top.

[0063] <Third Embodiment> This embodiment provides a method for detecting air pressure, referencing... Figure 21 The method includes the following steps: Step S1: Inject compressed gas into the pressure container on the marine skid. Before the compressed gas is injected into the pressure container, it is stabilized and filtered by the marine skid's container pressure detection auxiliary equipment. Step S2: After the air pressure in the pressure vessel reaches the detection condition, the air pressure of the pressure vessel is tested. Step S3: After completing the air pressure test, the gas in the pressure vessel is discharged to the outside atmosphere. Before the gas in the pressure vessel is discharged to the outside atmosphere, it is silenced by the container air pressure test auxiliary equipment on the marine skid.

[0064] Specifically, in step S1, compressed gas is injected into the pressure vessel by a compressor, and the pressure stabilization, filtration and drying treatments are performed on the marine skid container pressure detection auxiliary equipment provided in the first or second embodiment of this application before the compressed gas is injected into the pressure vessel. In step S3, the marine skid container pressure detection auxiliary equipment provided in the first or second embodiment of this application can also be used to perform noise reduction treatment on the gas discharged from the pressure vessel.

[0065] Furthermore, in step S2, various pressure detection devices and methods known to those skilled in the art can be used, such as pressure detection of pressure vessels, for example, measuring pressure changes inside the pressure vessel using a pressure sensor, or determining the location of a leak by detecting noise accompanying gas leakage on the surface of the pressure vessel. This application does not limit the means used for pressure vessel pressure detection.

[0066] The specific embodiments of this application have been described in detail above. For those skilled in the art, several improvements and modifications can be made to this application without departing from the principle of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
