[0014] An integrated oxygen generation system according to an embodiment of this utility model has at least the following beneficial effects:

[0015] (1) This system integrates core equipment such as an air compressor, refrigerated dryer, filter device, air-oxygen separator, air storage tank, oxygen storage tank, and oxygen booster into a single chassis, with a cleverly designed internal structure. This highly integrated design significantly reduces the space occupied by the equipment. Compared with traditional oxygen generation systems, the footprint can be reduced by 10 to 20 times. Taking a 10 cubic meter / h oxygen generation device as an example, the footprint of this invention is only 2 square meters, while traditional molecular sieve oxygen generation systems require at least 40 square meters of installation space.

[0016] (2) By optimizing the airflow path through the air compressor inlet (i.e., the second air inlet), the second compartment, and the first air inlet, this system effectively reduces the noise level of the air compressor during operation.

[0032] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0033] Reference Figure 1-7The integrated oxygen generation system provided by this utility model mainly includes a complete chassis. Each side of the chassis is equipped with a cover to facilitate the operation and maintenance of the system. The following key components are installed inside the chassis: an air compressor, a refrigerated dryer, a filter device, an air-oxygen separator 1, an air storage tank 2, an oxygen storage tank 3, and an oxygen booster device. The main function of the air storage tank 2 is to store the high-pressure gas generated by the air compressor and ensure a stable and continuous pressure supply to the air-oxygen separator 1. The oxygen storage tank 3 is responsible for storing the oxygen separated by the air-oxygen separator 1 and ensuring a stable and reliable oxygen source for the oxygen booster device. The refrigerated dryer is responsible for cooling the high-temperature air generated by the air compressor, effectively removing moisture from the air and ensuring the dry operation of the system. The air compressor is responsible for providing the necessary high-pressure air to the system. The filter device is used to purify impurities, water, and oil from the compressed air, ensuring that the air quality entering the air-oxygen separator meets the requirements, thereby improving the efficiency and service life of oxygen separation. The chassis is divided into a first storage compartment and a second storage compartment in different locations. The first storage compartment is equipped with a first base 4 and a second base 5. An air-oxygen separator 1 is mounted on the first base 4, while an air storage tank 2 and an oxygen storage tank 3 are mounted on the second base 5. A first support plate 6 is located above the second base 5, and an oxygen booster device is mounted on the first support plate 6. The second storage compartment is further divided into a first partition chamber and a second partition chamber 10. A second support plate 7 is located in the middle of the first partition chamber. An air compressor can be installed in the upper partition chamber 8 of the second support plate 7, while a freeze dryer is installed in the lower partition chamber 9. A filter device can be installed in the second partition chamber 10. The upper cover of the second storage compartment has a first heat dissipation vent 11 and a first air inlet vent 12. The first heat dissipation vent 11 faces the air compressor to ensure that the heat generated by the compressor during operation can be dissipated in a timely manner. The first air inlet vent 12 faces the filter device, allowing fresh air to enter the chassis. A second air inlet 13, facing the air compressor, is provided between the first and second compartments 10 to further enhance airflow within the chassis. During system operation, fresh air can enter the chassis from the first air inlet 12, then enter the first compartment through the second air inlet 13, and blow directly onto the air compressor. This effectively reduces the temperature of the air compressor head, oil, and compressed air, achieving a cooling effect. The hot air from the compressor is finally discharged through the first heat dissipation exhaust vent 11, forming a highly efficient closed-loop airflow. Furthermore, the duct design between the second compartment 10 and the first air inlet 12 not only effectively reduces the operating noise of the air compressor but also provides secondary cooling for the connecting pipes between the air compressor and the moisture filter in the filter unit.

[0034] Furthermore, the side cover of the second storage compartment is equipped with a third air inlet 14, which faces the freeze dryer to provide necessary fresh air to the freeze dryer. Simultaneously, the upper cover of the first storage compartment is equipped with a second heat dissipation exhaust vent 15, which faces the air-oxygen separator 1, ensuring that the heat generated by the air-oxygen separator during operation can be dissipated in a timely manner. To further optimize the system's heat dissipation performance, a removable partition 16 is provided between the first compartment and the first storage compartment. The partition 16 has a mounting hole 17 for installing heat dissipation equipment (such as a cooling fan). Specifically, the installed heat dissipation equipment is designed to face the freeze dryer to more effectively reduce its temperature. During system operation, fresh air can enter the first compartment from the third air inlet 14 and blow directly onto the freeze dryer, providing the necessary cooling effect. Subsequently, this fresh air, propelled by the heat dissipation equipment, is delivered to the air-oxygen separator 1, further helping to reduce its temperature. Finally, the hot air is discharged from the casing through the second heat dissipation exhaust vent 15, forming an efficient closed-loop airflow. This process not only effectively cools the compressor and heat sink of the freeze dryer, but also ensures that the temperature inside the air-oxygen separator 1 is maintained within the ideal range of 30-40 degrees Celsius, thereby improving the stability and performance of the entire system. Notably, the partition 16 effectively isolates the first compartment from the first storage compartment, preventing hot air blown from the heat dissipation equipment to the air-oxygen separator 1 from flowing back to the freeze dryer, ensuring unidirectional heat flow and improving the system's heat dissipation efficiency. When the heat dissipation equipment needs to be disassembled or repaired, the partition 16 can be easily removed, providing sufficient operating space for personnel and simplifying the maintenance workflow.

[0035] It is worth noting that in traditional molecular sieve oxygen generation systems, the control of the air compressor and the oxygen generation system are often independent. This results in up to 80% of the energy consumption during the molecular sieve oxygen generation process being concentrated in the air compression stage. In this embodiment, by employing the latest neodymium-titanium inverter technology to drive the air compressor, the power consumption of the air compressor can be significantly reduced, thereby achieving a high degree of energy saving. By introducing neodymium-titanium inverter technology, not only can the operation of the air compressor be controlled more effectively, but its working state can also be flexibly adjusted according to actual needs, thus avoiding unnecessary energy waste.

[0036] In some feasible embodiments, the outer wall of the chassis is equipped with a touch screen 18 and a brake button 19 to meet the user's needs for system monitoring and emergency operation. The touch screen 18, as a human-machine interface, can be closely connected to the system's PLC controller, displaying key control parameters of the oxygen generation system in real time. These parameters include at least oxygen purity, temperature, flow rate, and pressure, providing users with a comprehensive and intuitive monitoring experience. When the system detects any abnormality in these control parameters, the user can respond quickly by pressing the brake button 19. The brake button 19 is designed to handle emergencies; once pressed, it immediately cuts off the system's power supply, effectively preventing potential safety hazards and ensuring the safety of personnel and equipment. The coordinated operation of the touch screen 18 and brake button 19 not only improves the system's monitorability and operability but also significantly enhances its safety and reliability.

[0037] In some feasible embodiments, the air-oxygen separator 1 mainly consists of a first molecular sieve adsorption tower 20 and a second molecular sieve adsorption tower 21. These two towers serve as containers filled with molecular sieves, achieving the separation of oxygen from the air through the adsorption characteristics of the molecular sieves. Specifically, the first molecular sieve adsorption tower 20 and the second molecular sieve adsorption tower 21 alternately perform adsorption operations, thereby effectively separating oxygen from the air and producing high-purity oxygen with a purity of up to 93% ± 3%. In this embodiment, in the application scenario of the oxygen booster device, the initial pressure of the oxygen separated from the first molecular sieve adsorption tower 20 and the second molecular sieve adsorption tower 21 is typically in the range of 0.4-0.5 MPa. However, for certain special applications, the pressure of the oxygen can be further increased to 0.8-1.0 MPa by the booster device to meet higher usage requirements.

[0038] In some feasible embodiments, to enhance the flexibility and controllability of the system, both the first molecular sieve adsorption tower 20 and the second molecular sieve adsorption tower 21 are equipped with a balancing valve mounting base 22 and a solenoid valve mounting base 23. The design of these mounting bases not only facilitates the installation and connection of the balancing valve and the solenoid valve, but also improves the stability and reliability of the entire air-oxygen separation system.

[0039] It is worth noting that the second compartment 10 serves as both a mounting box for the filter device and a silencer and cooling box for the air compressor. Specifically, the presence of the second compartment 10 is crucial for reducing the noise of the air compressor. Without the noise reduction treatment provided by the second compartment 10, the air compressor would directly draw in fresh air from the outside environment without passing through the buffer and filtration of the first air intake vent 12 and the second compartment 10, resulting in very loud operating noise. In particular, when the second air intake vent 13 is designed as a hollow mesh, without the sound insulation effect of the second compartment 10, the operating noise of the air compressor would be more easily transmitted directly to the external environment, causing unnecessary disturbance to the surrounding environment and personnel. Therefore, the second compartment 10 not only provides installation space for the filter device but also effectively reduces the operating noise of the air compressor and provides it with the necessary cooling environment.

[0040] In some feasible embodiments, the filter device consists of a moisture filter, a main duct filter, and a particulate filter (also known as a precision filter). In the system's piping connections, the exhaust port of the air compressor is first connected to the moisture filter, and then sequentially connected to the main duct filter. The outlet of the main duct filter is connected to the inlet of the refrigerated dryer, and the outlet of the refrigerated dryer is then connected to the inlet of the particulate filter, whose outlet is connected to the air receiver tank 2.

[0041] Furthermore, the air storage tank 2 is not only connected to the air-oxygen separator 1, but also connected to the oxygen storage tank 3 through the air-oxygen separator 1. The oxygen storage tank 3 can serve as the oxygen source for the oxygen booster device, providing it with a stable oxygen supply. It is worth noting that the oxygen storage tank 3, in addition to being connected to the oxygen booster device, also has the flexibility to connect to the main pipeline or an external oxygen storage tank. If connected to an oxygen booster device, this device can also be selectively connected to the main pipeline or an external oxygen storage tank. In this embodiment, through the stepless pressure regulation function of the air compressor, the air storage tank 2 can be directly connected to the air-oxygen separator 1 without the need for an intermediate pressure reducing device. Compared with traditional molecular sieve oxygen generation systems, this avoids the problem of inconsistent pressure adjustment caused by pressure reducing devices, thereby ensuring the stability of oxygen production and the accuracy of oxygen purity during operation of each machine.

[0042] In addition, to further enhance the intelligence and stability of the system, a first pressure sensor is installed inside the air tank 2. When the first pressure sensor detects that the pressure value inside the air tank 2 exceeds a preset value, the air compressor can automatically adjust its output pressure to ensure the safe and stable operation of the system.

[0043] In some feasible embodiments, a second pressure sensor is installed inside the oxygen storage tank 3 to monitor the oxygen pressure in the tank in real time. Simultaneously, a third pressure sensor is installed on the outlet pipe of the oxygen booster device, which monitors the oxygen pressure after the booster operation in real time. When the second pressure sensor detects that the pressure inside the oxygen storage tank 3 reaches or exceeds the preset start-up pressure of the oxygen booster device, the device automatically starts and performs the booster operation. During this process, the third pressure sensor continuously monitors and records the boosted oxygen pressure to ensure its stability and safety. Through the coordinated operation of the second and third pressure sensors, the system can precisely control the pressure inside the oxygen storage tank and automatically activate the booster device when needed to meet the oxygen pressure requirements of different application scenarios.

[0044] In some feasible embodiments, the second storage compartment is further divided into a third partitioned compartment, which can be further subdivided into a detection chamber 24 and a control chamber 25. The detection chamber 24 is equipped with an oxygen purity detector and a dew point temperature detector, which can be used to monitor the oxygen purity and dew point temperature in the oxygen storage tank 3 in real time. Both the oxygen purity detector and the dew point temperature detector are electrically connected to the touchscreen 18, ensuring that the user can obtain the detection data in real time and make corresponding operational adjustments. To effectively dissipate the oxygen generated during the detection process, the upper cover of the detection chamber 24 is equipped with a third heat dissipation vent 26.

[0045] In some feasible embodiments, the control room 25 is equipped with a distribution box, controller, and frequency converter for power distribution, logic control, and frequency conversion regulation of the system. A fourth air intake vent 27 and a fourth exhaust vent 28 are respectively installed on the two side covers of the control room 25. The fourth exhaust vent 28 faces the air compressor 19 to more effectively utilize the waste heat from the air compressor for cooling. Furthermore, to enhance the system's heat dissipation, a cooling fan is installed on the first exhaust vent 11. During system operation, fresh air enters the control room 25 through the fourth air intake vent 27, carrying away the heat generated by the equipment, and is exhausted into the vicinity of the air compressor 19 through the fourth exhaust vent 28. Subsequently, this hot air is further heated by the waste heat from the air compressor 19 and finally exhausted outside the system through the cooling fan at the first exhaust vent 11, thus achieving effective heat dissipation and circulation for the entire system.

[0046] In some feasible embodiments, the side wall of the second compartment 10 is provided with a first pipe through-hole 29, a second pipe through-hole 30, and an vent valve 31. Both the first pipe through-hole 29 and the vent valve 31 face the air storage tank 2 for pipe connection. The vent valve 31 also functions to connect to the oxygen storage tank 3 to meet the system's needs under different operating conditions. The second pipe through-hole 30 faces the freeze dryer, facilitating pipe connection between the freeze dryer and the second compartment 10. Furthermore, an air compressor exhaust port 32 is provided above the first compartment. Through this exhaust port, the air compressor can be easily connected to the main pipeline filter, thus achieving docking of the air compressor's exhaust with the main pipeline filter.

[0047] In some feasible embodiments, the bottom of the control room 25 is also equipped with a power distribution trough 33, which allows the cables, lines or related components of the power distribution box to be connected and distributed through the power distribution trough 33.

[0048] In some feasible implementations, when multiple integrated oxygen generation systems operate simultaneously, they possess the ability to communicate and coordinate with each other. The system can automatically adjust the number of operating integrated oxygen generation systems based on the oxygen consumption of the terminals by monitoring pipeline flow and oxygen purity in real time, thereby effectively saving energy and reducing operating costs. Furthermore, the production process of integrated oxygen generation systems can adopt a highly integrated and standardized production method. All pipelines are installed and commissioned in the factory and undergo rigorous inspection and testing to ensure that each process meets the prescribed quality standards. This production method allows the equipment to be put into use directly after delivery to the installation site without additional installation and commissioning work. In contrast, traditional molecular sieve oxygen generation systems require the separate procurement of individual components from various equipment manufacturers and the deployment of professional personnel to the site for pipeline installation. Due to inconsistent installation procedures, various problems often arise, leading to project delays and increased investment costs. In addition, the equipment commissioning and connection work of traditional systems also consumes a significant amount of time and effort; the installation and commissioning cycle of a project is typically no less than 10 days. The integrated oxygen generation system in this embodiment achieves standardized and modular production through a unified factory installation process. This eliminates the need for on-site personnel to install each component and pipeline, significantly shortening the project timeline and reducing investment costs. This production method not only improves production efficiency but also ensures consistent and stable product quality.

[0049] It should be noted that this application does not impose strict limitations on the specific shape, structure, and layout of the air intake vents, heat dissipation vents, and other components mentioned in the above embodiments. As long as the design of these components can meet the functional requirements of the system, ensure smooth airflow and good heat dissipation, and facilitate installation and maintenance, they are considered to comply with the requirements of this application.

[0050] The working process of this integrated oxygen generation system is illustrated below with a specific example.

[0051] First, press the system power button on the touchscreen 18. The freeze dryer will start first and enter a stable operating state. Then, the air compressor will start working, producing compressed air at 0.5 to 0.7 MPa. This compressed air will pass sequentially through a moisture filter, a main pipeline filter, the freeze dryer, and a precision filter (also known as the air filtration and drying section), finally flowing into the air storage tank 2. A pressure sensor is installed in the air storage tank 2 to monitor the pressure inside the tank in real time. When the pressure reaches the preset value, the air compressor will automatically adjust its output pressure to maintain stable system pressure. Next, the air-oxygen separator 1 will start, separating oxygen from the compressed air and delivering this oxygen to the oxygen storage tank 3. The oxygen storage tank 3 is also equipped with a pressure sensor and is connected to a pipeline to an oxygen purity detection device and a dew point temperature detection device. If the detected oxygen purity or dew point temperature does not meet the qualified standards, the system will issue an alarm. When the oxygen pressure in the oxygen storage tank 3 reaches the set value, the system will enter standby mode. If the pressure drops below the set start pressure, the air-oxygen separator will restart to replenish oxygen. If the system is connected to an oxygen booster, that device will also have a set start-up pressure. When the pressure in oxygen storage tank 3 reaches this set value, the oxygen booster will start and begin pressurization. A pressure sensor is also installed at the outlet pipe of the oxygen booster to monitor the pressurized oxygen pressure in real time. When the pressure in the main pipeline or external storage tank reaches the set value, the oxygen booster will stop working and enter standby mode. If the pressure drops below the set start-up value again, the oxygen booster will automatically restart and begin pressurization.
