Abstract
Description
Technical Field
[0001] This utility model belongs to the field of static sterile air systems, specifically, it relates to a static sterile air system. Background Technology
[0002] With the continuous development of modern technology, the requirements for air quality are becoming increasingly stringent, especially in industries such as medical, pharmaceutical, and food processing. Currently, various air filtration and purification technologies exist on the market, but they still have some shortcomings in achieving highly efficient sterilization and filtration.
[0003] In existing technologies, many air purification systems employ single or dual filtration methods, commonly including high-efficiency HEPA (particulate air) filters and activated carbon filters. These systems are generally effective at removing most particulate matter and odors from the air. However, to address this issue, some existing systems have introduced highly efficient (ultraviolet) sterilization technology. While this has some effect on disinfection, its effectiveness and applicability are affected by environmental and operational factors. Furthermore, these technologies often cannot achieve continuous, modular air processing.
[0004] In recent years, multi-layer filtration technology has gained attention for its ability to improve air quality through multiple layers of filtration and purification. Some studies and patents have proposed triple or quadruple filtration solutions, but these generally suffer from large equipment size, high surface area, and complex maintenance. For example, some existing multi-layer filtration systems combine mechanical, chemical, and optical methods to attempt to remove harmful substances from the air at different stages. However, the overall effectiveness of these systems remains limited.
[0005] Therefore, a new type of air filtration and sterilization system is needed in advance, capable of ensuring efficient sterilization while achieving more sophisticated design and alarm notifications. A sterilizable sterile air system with a four-stage filtration design can provide a more comprehensive solution to address the shortcomings of existing technologies, thereby continuously improving product quality and safety.

A sterilization shut-off valve 23 is installed on the second pipe 25 to the right of the second pressure monitor 24. All electrical equipment involved in this application can be powered by a storage battery or an external power source.
[0029] like Figure 1 As shown, both the first pipe 17 and the second pipe 25 in this embodiment are curved.
[0030] like Figure 1 As shown, in this embodiment, the first pipe 17 passes through the compressed air intake valve 1 and extends to the upper and lower sides, with the upper end being an air intake port. The compressed air intake valve 1 is fixedly connected to the first pipe 17.
[0031] like Figure 1 As shown, in this embodiment, the first pipe 17 passes through the connection end of the coarse filter 11, the activated carbon filter 12, and the fine filter 13 and extends to the left and right sides, and is fixedly connected to the connection end of the coarse filter 11, the activated carbon filter 12, and the fine filter 13.
[0032] like Figure 1 As shown, in this embodiment, the first pipe 17 passes through the negative pressure regulating valve 14 on both sides, and the first pipe 17 is fixedly connected to the connection end of the precision filter 15.
[0033] like Figure 2 As shown, in this embodiment, the second pipe 25 passes through the steam inlet valve 2 from top to bottom and extends to the upper and lower sides, with the upper end being the steam inlet.
[0034] like Figure 2 As shown in this embodiment, the second pipe 25 extends through the connecting end of the steam dual filter 21 on both sides, and the connecting end of the steam dual filter 21 is fixedly connected to the second pipe 25.

[0036] Example 1:
[0037] Compressed air is controlled via compressed air inlet valve 1 to ensure that air enters the system at appropriate flow and pressure. Compressed air inlet valve 1 has an automatic adjustment function to adapt to different production needs. Air first enters the first coarse filter element 11, which uses high-efficiency fiber material to effectively remove grease and moisture from the compressed air, preventing contamination of subsequent filtration processes. After passing through coarse filter 11, the air enters the second activated carbon filter element 12. At this stage, activated carbon filter 12 effectively adsorbs odors, esters, and aldehydes from the air, further improving air quality and ensuring the requirements of a sterile environment. Air then enters the third fine filter element 13, which uses high-efficiency microporous filter material to filter gaps larger than 1.0 micrometer, ensuring that only clean air enters the next step. The filtered air is then adjusted to the required standard air backup pressure via negative pressure regulating valve 14. This valve has a rapid response capability to adapt to pressure changes during production. The air passes through a final precision filter 15, which uses ultra-high efficiency filtration technology to filter out particles larger than 0.2 microns. This step ensures that the air meets the standard of sterility and is suitable for applications with strict air quality requirements.
[0038] The sterilization mode introduces steam through steam inlet valve 2, which ensures a stable steam flow into the system. The steam first enters a dual steam filter 21, which uses specially designed filter media to ensure the removal of particles larger than 0.2 microns, protecting the efficiency and operation of subsequent equipment. The filtered steam then enters steam pressure reducing valve 22, adjusting the steam pressure to 1 bar to maintain appropriate steam pressure and flow during sterilization. Finally, the steam passes through sterilization shut-off valve 23 into the final precision filter 15. At this stage, the steam temperature reaches 125°C and lasts for 30 minutes, effectively eliminating bacteria and monomers in the air through thermal sterilization, ensuring the air meets stringent standards.
[0039] Furthermore, the entire system is equipped with real-time monitoring equipment to monitor pressure, temperature, and flow rate at each stage, ensuring the system operates in optimal condition. Simultaneously, a feedback mechanism is implemented to automatically adjust operating parameters for each process, guaranteeing that air quality consistently meets requirements. This results in a lower-cost, more efficient, and faster four-stage filtration and sterilization system for sterile air, solving the problems of high cost, low efficiency, complex structure, and susceptibility to secondary pollution inherent in existing air filtration and sterilization systems.
