Description

Technical Field

[0001] This application relates to the field of air compression station technology, and in particular to a gas compression component and integrated gas station. Background Technology

[0002] Gas compression systems are indispensable basic equipment in modern industrial manufacturing, widely used in the production and supply of industrial gases such as compressed air, oxygen, and nitrogen. In industries such as automobile manufacturing, electronic assembly, food processing, textile machinery, and chemical processes, compressed gases serve as power sources, process media, or control gas sources, and the stability, purity, and energy efficiency of their supply directly affect the operating efficiency of production systems and product quality.

[0003] Traditional gas compression systems typically consist of multiple independent components connected by pipelines, including compressed gas production components, an oil-gas separator (oil-gas tank), a compressed gas cooling component, a dehydration device, and a gas storage tank. The oil-gas separator often employs a vertical structure. This vertical oil-gas tank is usually arranged side-by-side with the compressor main unit (compressor head), motor, and other compressed gas production components, connected via external pipelines. While the vertical design utilizes vertical space to some extent, the separate installation of the compressor main unit and the vertical oil-gas tank, coupled with the required piping and fittings, results in the system occupying a significant amount of horizontal space, hindering miniaturization and compact layout.

[0004] Therefore, there is an urgent need for a new gas compression component design that can fundamentally optimize the spatial layout problem. Utility Model Content

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the first air inlet includes a first straight pipe and a second straight pipe; the first straight pipe passes through the tank body and is sealed to the tank body by the outer wall, and one end of the first straight pipe in the cavity is closed, while the other end is open and forms the air inlet end of the first air inlet; the second straight pipe is located on the upper side of the cavity, one end of the second straight pipe is connected to the first straight pipe, and the other end extends toward the oil removal tank, and the air outlet extends into the oil removal tank from the opening of the oil removal tank, and the air outlet direction points to the bottom of the oil removal tank, and there is a gap between the second straight pipe and the first straight pipe at the connection point and the closed end of the first straight pipe.

This, along with the connecting pipes between the vertical oil-gas tank and the compressed gas production component, results in a larger horizontal space occupation in the separate installation structure.

[0022] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] See Figure 1-12 In order to overcome the problem that the traditional gas compression system has a separate installation method for the compressed gas production component and the vertical oil and gas tank, and the connection requires pipes and fittings, which causes the system to occupy a lot of space in the horizontal plane and is not conducive to the miniaturization and compact layout of the equipment, this application discloses a gas compression component 10 and an integrated gas station 20.

[0025] On the one hand, such as Figure 3 As shown, this application discloses a gas compression assembly 10, which can be used for the production of compressed gas, such as for the production of compressed air in an industrial manufacturing system.

[0026] In the embodiments of this disclosure, such as Figure 3 As shown, this gas compression assembly 10 includes a compressed gas production assembly 200 and a horizontal oil-gas tank 300. The compressed gas production assembly 200 includes a compressor head 202 (such as the main unit of an air compressor, model DLG15AA, from Taitian Group) for producing compressed gas and a motor 201 (such as a permanent magnet synchronous motor 201) for driving the compressor head 202. The horizontal oil-gas tank 300 has mounting feet 321 on its lower side and a mounting bracket 320 on its upper side. The compressor head 202 is connected to the mounting bracket 320, and the motor 201 is connected to the compressor head 202. The compressed gas production assembly 200 produces the required gas. Since the compressor head 202 of the compressed gas production assembly 200 requires lubricating oil during operation, the compressed gas produced by the compressor head 202 is a mixture of gas and oil. Therefore, the horizontal oil-gas tank 300 is used for the primary purification of the compressed gas.

[0027] The compressor head 202 is responsible for producing compressed gas, and the motor 201 drives the compressor head 202. The horizontal oil and gas tank 300 is supported on the ground or other dedicated installation location by mounting feet 321, and is connected to the compressor head 202 through mounting brackets 320 to form an integral structure. The compressor head 202 is directly fixed to the mounting brackets 320, and the motor 201 is connected to the compressor head 202, realizing the integration of power transmission and gas compression.

[0028] This gas compression assembly 10 directly connects the compressor head 202 to the horizontal oil-gas tank 300, avoiding the traditional vertical oil-gas tank and separate installation structure where the compressed gas production assembly is placed on one side and the vertical oil-gas tank on the other side, along with the connecting pipes between the vertical oil-gas tank and the compressed gas production assembly. This avoids the large space occupation in the horizontal plane of the separate installation structure. This gas compression assembly 10, by adopting a longitudinally integrated design of the compressed gas production assembly 200 and the horizontal oil-gas tank 300, achieves a compact layout, reducing overall size and weight, and particularly reducing the space required in the horizontal plane, facilitating miniaturization (such as the micro KC2 model). Furthermore, the mounting bracket 320 and support feet provide stable support, simplifying the installation process and improving system reliability and maintenance convenience.

[0029] In the embodiments of this disclosure, such as Figure 3 As shown, the machine head 202 has an exhaust port 203 and an oil return port 204. The horizontal oil-gas tank 300 includes a tank body 301, an oil stripping groove 303, an isolation groove 305, a first air inlet 308, a first air outlet 314, and an oil outlet 318. Mounting feet 321 and mounting supports 320 are fixedly mounted on the tank body 301. The tank body 301 has an internal cavity 302, which is horizontally positioned along its length; for example, during use, the length of the cavity 302 is kept horizontal. The oil stripping groove 303 is located on the upper side of one end of the cavity 302, with its opening facing the other end. The isolation groove 305 is located on the upper side of the cavity 302, and its opening direction is the same as that of the oil stripping groove 303. The first air inlet 308 is located on the tank body 301, and the air outlet of the first air inlet 308 points towards the oil removal tank 303. The first air outlet 314 is located on the tank body 301, and the air inlet end of the first air outlet 314 is connected to the isolation tank 305. The oil outlet 318 is located on the tank body 301, and the oil inlet end of the oil outlet 318 extends to the lower side of the cavity 302. During installation, the machine head 202 is mounted on the mounting bracket 320, and the exhaust port 203 needs to be connected to the first air inlet 308. At the same time, the oil return port 204 is connected to the oil outlet 318.

[0030] During use, the tank 301 (cavity 302) is placed horizontally. Generally, a certain amount of oil is stored in the cavity 302. This oil is mainly used for lubrication of the compressed air production mechanism of the compressed gas production component 200. The amount of lubricating oil exceeds the oil inlet end of the oil outlet 318. First, the compressed gas produced by the working head 202 flows out from the exhaust port 203 and then is introduced into the cavity 302 from the first air inlet 308. This causes the compressed gas to impact the oil removal tank 303 at high speed as it flows into the cavity 302 from the first air inlet 308. The impact of the compressed gas on the oil removal tank 303 causes the compressed gas to turn and disperse at high speed. Due to the high density of the oil and the viscosity of the oil on the inner wall of the oil removal tank 303, the oil droplets or oil mist in the compressed gas are quickly separated from the compressed gas. The separated oil sinks naturally to the bottom area of ​​the cavity 302 due to gravity, while the compressed gas flows to the isolation tank 305. First, the isolation tank 305 further captures residual oil droplets and oil mist. The separated and purified gas is discharged from the gas outlet, while the separated oil flows out from the oil outlet 318 under the pressure of the gas pressure and is cooled and circulated to the compressed gas production assembly 200. The oil outlet 318 extends to the lower side of the cavity 302, thereby ensuring that oil is taken from the bottom of the cavity 302 and preventing air from escaping from the oil outlet 318.

[0031] The special design of the horizontal oil-gas tank 300 enables efficient oil-gas separation, reduces the oil content in compressed gas, and features a compact structural design that facilitates the miniaturization of the oil-gas separation device and saves installation space required for application. In particular, by placing the compressed gas production component 200 on top of the horizontal oil-gas tank 300, the planar space occupied by the compressed gas production component 200 and the horizontal oil-gas tank 300 when they are installed separately is greatly reduced.

[0032] In the embodiments of this disclosure, such as Figure 7 and Figure 8As shown, the tank body 301 is generally a cylindrical tank, and a detachable end cap 329 is provided at one end to facilitate access to the cavity 302 during routine maintenance by opening the end cap 329. Simultaneously, a horizontal baffle 304 is provided inside the tank body 301. The horizontal baffle 304 is located at one end of the cavity 302, for example, at the end opposite to the end cap 329, with the horizontal baffle 304 horizontally positioned so that three sides of the horizontal baffle 304 are welded and fixed to the inner wall of the cavity 302, thereby creating an oil removal groove 303 on the upper side of the end of the cavity 302. Meanwhile, an L-shaped baffle 306 is provided inside the tank body 301. The L-shaped baffle 306 is located on the upper side of the cavity 302, with one section of the L-shaped baffle 306 placed horizontally and the other section extending upward, so that the remaining side edges of the L-shaped baffle 306, except for the side near the opening of the isolation groove 305, respectively contact the inner wall of the cavity 302 and are welded and fixed to the inner wall of the cavity 302, thereby separating the isolation groove 305 through the L-shaped baffle 306.

[0033] Compressed gas is guided and impacts the wall of the oil removal tank 303 for oil-gas separation. An L-shaped baffle 306 is positioned on the upper side of the cavity 302, forming an isolation groove 305 through horizontal and vertical sections. Gas must flow around this groove to enter, extending its path, promoting oil droplet settling, and connecting the outlet to the isolation groove 305 to ensure that only separated gas is discharged. This design is simple in structure, easy to manufacture, and enhances the efficiency and stability of oil-gas separation. Furthermore, the L-shaped baffle 306 provides additional separation space, reducing oil mist carryover after compressed gas separation.

[0034] In some implementations, such as Figure 8 As shown, the isolation groove 305 and the oil removal groove 303 are respectively disposed at both ends of the cavity 302. A partition plate 307 is disposed in the middle of the cavity 302. The thickness direction of the partition plate 307 is perpendicular to the length direction of the cavity 302. The two lateral sides of the partition plate 307 are sealed to the inner wall of the cavity 302, and the partition plate 307 has through channels on its upper and lower sides. The through channels can be formed by ensuring that the upper and lower sides of the partition plate do not contact the inner wall of the cavity 302; or they can be formed by slotting (drilling) the upper and lower sides of the partition plate.

[0035] A partition plate 307 is located in the middle of the cavity 302, with its thickness direction perpendicular to the length direction of the cavity 302. It is sealed on both sides laterally and has channels on both the upper and lower sides. When gas flows through the partition plate 307, it forms eddies or decelerates. Oil droplets and oil mist sink due to inertia impacting the surface of the partition plate 307, while the gas continues to flow through the upper and lower channels, achieving multi-stage separation. This extends the airflow path, increases the separation time, and further improves the compressed gas purification effect. At the same time, the partition plate 307 has a simple structure and does not add excessive resistance, thus improving overall separation performance at a low cost.

[0036] In some implementations, such as Figure 8 As shown, the oil outlet 318, connected to the return oil port 204, has a downward extension section 319 on the tank body 301. The oil inlet of the oil outlet 318 is located at the lower end of the extension section 319, close to the bottom of the cavity 302. This allows the separated oil to be collected from the lowest point of the cavity 302, avoiding gas contamination or the influence of oil level fluctuations. Simultaneously, the upper end of the extension section 319 can be above the liquid level inside the cavity 302, preventing oil from flowing into the oil outlet 318 by gravity. Instead, the air pressure inside the cavity 302 forces the separated oil outwards. This further ensures thorough oil collection, reduces the risk of gas leakage, and features a simple structure and convenient maintenance.

[0037] In the embodiments of this disclosure, such as Figure 8 and Figure 9 As shown, the first air inlet 308 includes an L-shaped air inlet pipe 309. One section of the air inlet pipe 309 is located on the upper side of the cavity 302, and the outlet end of the air inlet pipe 309 extends into the oil-removing tank 303 from the opening of the oil-removing tank 303, with the outlet direction pointing towards the bottom of the oil-removing tank 303, i.e., towards the side of the oil-removing tank 303 opposite to the opening. The other section of the air inlet pipe 309 extends outward from the tank body 301 and is fixedly connected to the tank body 301. This better constrains the flow direction of the compressed gas when it enters the cavity 302, ensuring that the compressed gas can impact the oil-removing tank 303 in a better manner, thereby ensuring the oil-gas separation effect.

[0038] Furthermore, such as Figure 9 As shown, the air inlet pipe 309 includes a first straight pipe 310 and a second straight pipe 311. The first straight pipe 310 passes through the tank body 301 and is sealed to the tank body 301 with its outer wall. One end of the first straight pipe 310 is closed and the other end is open within the cavity 302, serving as the air inlet end of the first air inlet 308. The second straight pipe 311 is located within the cavity 302. One end of the second straight pipe 311 is connected to the first straight pipe 310, and the other end extends towards the oil removal tank 303. There is a distance L between the connection point of the second straight pipe 311 and the closed end of the first straight pipe 310. The outer end of the first straight pipe 310 is connected to an oil and gas input pipe. After the compressed gas enters the first straight pipe 310, it first impacts the closed end of the first straight pipe 310. The cavity between the closed end and the second straight pipe 311 functions as an oil removal tank 303. This extends the number of processing stages in oil-gas separation and further enhances the purification capacity of compressed gas.

[0039] In the embodiments of this disclosure, such as Figure 3As shown, the compressed gas production assembly 200 is directly mounted on the mounting bracket 320. Simultaneously, a first flange 312 can be installed on the outer end of the first straight pipe 310, positioned near the mounting bracket 320, or rigidly connected to the mounting bracket 320. This allows the first flange 312 (first air inlet 308) to directly connect with the exhaust port 203 when the compressor head 202 is mounted on the mounting bracket 320, achieving a more compact installation method. Furthermore, the overall structure is more robust and suitable for small and micro-sized equipment with limited space.

[0040] In some implementations, such as Figure 7 and Figure 8 As shown, an annular groove 313 is provided on the first flange 312 around the air inlet end of the first air inlet 308. This annular groove 313 is used to place an O-ring seal to ensure reliable sealing when the first flange 312 is directly connected to the exhaust port 203 of the machine head 202. In normal operation, the seal at the air inlet end of the oil and gas tank is an asbestos gasket, which is unreliable and needs to be replaced after disassembly. However, the connection of this design structure has high sealing reliability and can be reused, which is convenient for repeated disassembly and assembly during debugging or maintenance.

[0041] In some implementations, such as Figure 7 As shown, an observation hole 322 is provided on the tank body 301, and a transparent observation window 323 is provided on the observation hole 322. The observation hole 322 is generally located above the lower end of the oil outlet 318, for example, in the middle of the tank body 301. The standard for adding oil to the cavity 302 is generally to cover the oil inlet end of the oil outlet 318 and be located in the middle of the transparent observation window 323. This allows operators to directly observe the internal oil-gas separation status and oil level through the observation window, facilitating real-time monitoring and maintenance, and timely detection of abnormalities. This improves operational safety and convenience.

[0042] In some implementations, such as Figure 7 As shown, the tank body 301 is provided with an oil filling hole 324, and a removable plug 325 is provided on the oil filling hole 324. For example, the plug 325 is threadedly connected to the oil filling hole 324 to facilitate removable sealing of the oil filling hole 324. The oil filling hole 324 is generally located on the upper part of the tank body 301. Since the compressed gas production process continuously carries oil, resulting in oil loss, and oil is necessary for lubrication when the compressor head 202 is working, it can be observed through the observation window. When it is found that the oil is insufficient, the plug 325 can be opened to replenish oil into the cavity 302 through the oil filling hole 324.

[0043] In some implementations, such as Figure 7As shown, a drain port 326 is provided at the bottom of the tank 301, and a switch valve 327 is installed on the drain port 326. By placing the drain port 326 at the bottom of the tank 301 and equipping it with a switch valve 327 (such as a ball valve or gate valve), sediment, moisture, or impurities can be periodically discharged. This keeps the inside of the tank 301 clean and prevents blockage and corrosion. The valve is easy to operate, improving system reliability.

[0044] In some implementations, such as Figure 4 and Figure 5 As shown, a safety valve 328 is also installed on the tank 301. By installing the safety valve 328 on the tank 301, it automatically opens when the internal pressure exceeds a set value, releasing excess gas and preventing excessive pressure. Thus, the safety valve 328 on the tank 301 provides overpressure protection, preventing the tank 301 from exploding or being damaged. This ensures that the horizontal oil and gas tank 300 meets safety standards and guarantees long-term stable operation of the equipment.

[0045] On the other hand, with the development of industrial automation and the increasing demands for efficient production space utilization, the market demand for compact, highly integrated, and easy-to-install small gas compression components 10 is growing. Especially in space-constrained applications, such as small workshops, laboratories, mobile repair stations, or pneumatic units integrated into large equipment, traditional distributed designs that occupy large areas of planar space are no longer sufficient. Therefore, such as Figure 1-3 and Figure 12 As shown, this application also discloses a gas compression assembly 10, which is mainly used for the production of compressed air.

[0046] In the embodiments of this disclosure, such as Figure 1-3 and Figure 12 As shown, an integrated gas station 20 includes the aforementioned gas compression assembly 10, as well as a housing 100, a compressed gas cooling assembly 400, a gas storage tank 500, and a dehydration device 600. The gas compression assembly 10, the compressed gas cooling assembly 400, the gas storage tank 500, and the dehydration device 600 are all housed within the housing 100. This integrated gas station 20 saves space through its highly integrated design, making the gas station compact, easy to move, and easy to install. The housing 100 provides protection and environmental isolation, suitable for small industrial sites or mobile applications. Process optimization ensures continuous gas processing, improving production efficiency and gas quality.

[0047] The dehydration device 600 can typically be either a freeze dryer or a desiccant dryer, but to facilitate the miniaturization of this integrated gas station 20, the dehydration device 600 is preferably a desiccant dryer.

[0048] In the embodiments of this disclosure, such as Figure 1As shown, an air outlet 102 is provided on the top 101 of the housing 100. The compressed gas cooling assembly 400 is air-cooled. Figure 3 and Figure 12 As shown, the compressed gas cooling assembly 400 includes a heat exchanger 401 and a fan 404. The heat exchanger 401 is provided with an oil cooling passage 402 and a gas cooling passage 403. The heat exchanger 401 is located at the air outlet 102, and the fan 404 is located on one side of the heat exchanger 401. The fan 404 forces air to flow through the heat exchanger 401 and out of the air outlet 102. Typically, the heat exchanger 401 is located at the air outlet 102, and the fan 404 is located on the side of the heat exchanger 401 away from the air outlet 102, thereby dissipating heat by blowing air through the fan 404.

[0049] In some implementations, based on the above scheme, such as Figure 2 and, Figure 3 as well as Figure 12 As shown, the dehydration device 600, the gas storage tank 500, and the gas compression assembly 10 are all installed on the bottom of the housing 100. The dehydration device 600 is a desiccant dryer, and the dehydration device 600 and the gas storage tank 500 are located on the same side inside the housing 100. The gas compression assembly 10 is then located on the other side inside the housing 100, with the length of the horizontal oil-gas tank 300 parallel to the arrangement direction of the dehydration device 600 and the gas storage tank 500. The compressed gas cooling assembly 400 is positioned directly above the dehydration device 600, the gas storage tank 500, and the gas compression assembly 10, thus forming a highly integrated, rationally laid out, and compact miniature integrated gas station 20. The fan 404 blows air outwards, enabling the heat exchanger 401 to exchange heat and dissipate heat, and also creates a pressure difference between the inside and outside of the housing 100, prompting outside air to enter the housing 100 for heat dissipation.

[0050] pass Figure 3 and Figure 12 In contrast, based on the fact that the dehydration device 600, the gas storage tank 500, and the gas compression assembly 10 are all installed on the bottom of the housing 100, the dehydration device 600 is a desiccant, and the dehydration device 600 and the gas storage tank 500 are located on the same side inside the housing 100, and the gas compression assembly 10 is located on the other side inside the housing 100, with the length of the horizontal oil-gas tank 300 parallel to the arrangement direction of the dehydration device 600 and the gas storage tank 500, regardless of any changes in the design details of the compressed gas cooling assembly 400 and the horizontal oil-gas tank 300, or any differences in the layout of the gas and oil pipelines, the integrated gas station 20 of this application can be easy to maintain, i.e., convenient for the internal gas and oil pipeline layout, and has sufficient maintenance and operation space, while maintaining the advantages of compact structure, high integration, and convenient installation.

[0051] Furthermore, such as Figure 3 As shown, the oil path between the oil return port 204 and the oil outlet 318 passes through the oil cooling passage 402, thereby cooling the oil in the compressed gas production assembly 200 through the compressed gas cooling assembly 400. Simultaneously, the gas cooling passage 403 is connected in series to the first gas outlet 314 to cool the compressed gas through the compressed gas cooling assembly 400.

[0052] Furthermore, such as Figure 7 and Figure 8 As shown, a second flange 317 can also be provided on the first air outlet 314 to facilitate the installation of the mounting bracket 700 via the second flange 317, such as... Figure 3 As shown, a first filter 701 and a second filter 702 are installed via a mounting bracket 700. The first filter 701 is connected in series in the oil path between the oil return port 204 and the oil outlet 318 to filter solid impurities in the oil. The second filter 702 is connected in series in the first air outlet 314 to filter oil, water, and solid particles from the compressed gas flowing out of the first air outlet 314.

[0053] like Figure 8 As shown, a transition pipe 315 with a larger internal diameter (larger than the diameter of the inlet end of the first air outlet 314) is provided between the second flange 317 of the first air outlet 314 and the air inlet end. The inner diameter of the transition pipe 315 is generally set to 4 times the diameter of the inlet end of the first air inlet 308, thereby forming a buffer cavity 316 between the air inlet end and the second flange 317. The buffer cavity 316 can slow down the upward flow velocity of the compressed gas at this location, reduce the flow velocity, and prevent the flow velocity from being too high and carrying the bottom of the cavity 302 out together. In addition, the buffer cavity 316 can also obstruct the rising oil mist or oil droplets at this location, playing a role in filtration and purification.

[0054] Furthermore, such as Figure 3 As shown, when the gas compression assembly 10 is installed at the bottom of the housing 100, a shock-absorbing pad 205 is provided between the mounting support 321 and the bottom of the housing 100.

[0055] Among them, such as Figure 4-6 As shown, the gas storage tank 500 is provided with a second air inlet 503 and a second air outlet 504, and the annular guide groove 501 inside the gas storage tank 500 is as follows: Figure 6As shown, the annular guide channel 501 is attached to and surrounds the inner wall of the air storage tank 500. The lower side of the guide channel 501 is open. The second air inlet 503 is connected to the annular guide channel 501, and the air intake direction into the guide channel 501 is tangent to the guide channel 501. The second air outlet 504 is located above the annular guide channel 501. The second air inlet 503 is used to connect to the dewatering device 600 through a pipeline to introduce the dewatered and purified compressed air into the air storage tank 500 for buffering. The second air outlet 504 is typically used to connect to external air-using equipment.

[0056] In some implementations, such as Figure 4 and 5 As shown, the housing 100 is equipped with two gas storage tanks 500, and the two gas storage tanks 500 are connected in series to achieve capacity expansion and multi-stage filtration.

[0057] In some implementations, such as Figure 5 and Figure 6 As shown, the bottom of the gas storage tank 500 is provided with a drain outlet 505 for draining accumulated water (liquid), and the drain outlet 505 is provided with a discharge valve 506 for controlling the switch. Furthermore, a transparent observation port 507 for observing the internal liquid accumulation can also be provided at the lower end of the gas storage tank 500. Furthermore, the gas storage tank 500 is also provided with a pressure gauge 508 for monitoring internal air pressure, and a safety valve 328 to ensure internal pressure safety.

[0058] In one implementation, such as Figure 10 As shown, the integrated gas station 20 comprises a gas compression assembly 10, a compressed gas cooling assembly 400, a dehydration device 600 (such as a freeze dryer or desiccant), and a gas storage tank 500, all connected sequentially via pipelines. The gas compression assembly 10 produces compressed gas, which is then cooled by the compressed gas cooling assembly 400, dehydrated by the dehydration device 600, and temporarily stored in the gas storage tank 500. This scientifically designed compressed gas production process ensures that the compressed gas is dehydrated after cooling, improving dehydration efficiency and ensuring stable overall system operation. This solution achieves efficient compressed air production and processing, meeting the needs of miniaturized gas stations while reducing energy consumption and maintenance costs.

[0059] After being purified by the dewatering device 600, the compressed air enters the storage tank 500 through the second air inlet 503 and is sprayed at high speed into the annular guide channel 501. The guide channel 501 is axially arranged with an open lower side, and the second air inlet 503 is tangentially connected to the guide channel 501, thus causing the gas to enter the guide channel 501 tangentially and generate a swirling flow. Firstly, the centrifugal flow of the compressed air generates centrifugal force, further separating moisture and particulate matter from the gas. The guide channel 501 guides the airflow to prolong the residence time, improving the separation effect. Secondly, the viscosity of oil, water, and solid impurities on the inner side of the guide channel 501 promotes the purification effect of centrifugal separation. Furthermore, by positioning the second air outlet 504 higher than the guide channel 501, the gas leaves the storage tank 500 with an upward flow, causing water mist or oil mist in the compressed gas to condense and settle during this upward process, thus preventing water mist, oil mist, or solid impurities from flowing out of the storage tank 500 through the second air outlet 504. An annular baffle 502 can be further installed in the inner ring of the guide channel 501 on the side away from the inner wall of the gas storage tank 500. This annular baffle 502 prevents the compressed gas from carrying oil mist, water mist, or solid impurities upwards. This enhances the impurity removal capability of the gas storage tank 500, resulting in a compact structure while ensuring the quality of gas usage.

[0060] In another implementation, such as Figure 3 and Figure 11 As shown, the gas compression assembly 10, compressed gas cooling assembly 400, gas storage tank 500 and dehydration device 600 of this integrated gas station 20 are connected in sequence by pipelines so that compressed gas is produced by the gas compression assembly 10, cooled by the compressed gas cooling assembly 400, temporarily stored by the gas storage tank 500, and dehydrated by the dehydration device 600 when the compressed gas flows out of the gas storage tank 500 and enters the dehydration device 600.

[0061] The unique feature is that the compressed gas produced by the gas compression assembly 10 is at a high temperature. After being cooled by the compressed gas cooling assembly 400, a large amount of oil and water will be released. When the gas flow enters the gas storage tank 500, it will separate and settle to the bottom of the gas storage tank 500, thus achieving a purification and dehydration effect through the gas storage tank 500. Especially after the annular guide groove 501 is set in the gas storage tank 500, the purification effect of water and oil removal is further improved and guaranteed. The water removal device 600 (such as a freeze dryer or desiccant) can purify and dry the compressed gas to a higher standard.

[0062] However, before the compressed gas enters the dehydration device 600, most of the oil, water, and solid impurities in the compressed gas are removed by the gas storage tank 500. This reduces the workload of the dehydration device 600 and may even lower its configuration requirements. Furthermore, the compressed gas only passes through the dehydration device 600 before being used downstream, reducing unnecessary usage frequency and extending the service life of the dehydration device 600.

[0063] This gas compression assembly 10 and integrated gas station 20 vertically integrate the compressed gas production assembly 200 with the horizontal oil-gas tank 300, and optimize the internal flow channels and separation structure to create a novel gas compression system. This provides an effective solution for space-constrained applications where traditional decentralized designs occupying large areas of planar space are no longer sufficient. This not only significantly reduces the overall footprint of the equipment but also improves oil-gas separation efficiency and system reliability through structural innovation, meeting the core requirements of modern industry for compact, efficient, and easy-to-maintain compressed air systems.

[0064] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
