袋進(jìn)袋出BIBO的制作關(guān)鍵點在哪里？
袋進(jìn)袋出（Bag-In/Bag-Out，簡稱 BIBO）是一種用于高效空氣過濾器的更換技術(shù)，它允許在不接觸污染物的情況下安全地更換過濾器。這種技術(shù)特別適用于需要高安全性和防止污染擴(kuò)散的環(huán)境，如生物安全實驗室、醫(yī)院隔離病房、制藥和化工行業(yè)等。
工作原理：
1. 袋進(jìn)：新的高效空氣過濾器在安裝前被放置在一個特殊的保護(hù)袋內(nèi)。這個袋子通常由PVC或其他耐用材料制成，能夠密封并防止污染物逸出。
2. 安裝：將裝有新過濾器的保護(hù)袋通過BIBO接口送入過濾器箱體內(nèi)部，并將新過濾器安裝到位。
3. 袋出：當(dāng)需要更換過濾器時，使用保護(hù)袋將使用過的過濾器包裹起來，然后從箱體中取出。這樣可以確保在整個更換過程中，污染物被完全隔離，不會接觸到外部環(huán)境。
主要特點：
- 安全性：BIBO系統(tǒng)提供了一個安全的更換方法，防止了污染物的擴(kuò)散和操作人員的暴露。
- 氣密性：系統(tǒng)設(shè)計保證了與外界環(huán)境的完全隔離，確保了高氣密性。
- 維護(hù)簡便：通過使用保護(hù)袋，簡化了過濾器的更換過程，減少了維護(hù)時間和成本。
- 適用性廣：適用于多種需要高安全性的場合，如生物安全實驗室、醫(yī)療設(shè)施、制藥和化工行業(yè)等。
應(yīng)用場景：
- 生物安全實驗室：用于控制高致病性病原體的擴(kuò)散。
- 醫(yī)院隔離病房：用于防止傳染性病原體通過空氣傳播。
- 制藥行業(yè)：用于確保生產(chǎn)環(huán)境的清潔，防止交叉污染。
- 化工行業(yè)：用于處理和排放有害化學(xué)物質(zhì)，保護(hù)環(huán)境和人員安全。
技術(shù)難點
1. 高氣密性要求：BIBO過濾器需要在安裝、更換和檢測過程中保證與外界空氣完全隔離，這要求過濾器箱體和所有連接處具有極高的氣密性 。
2. 材料選擇：箱體通常采用不銹鋼整體焊接，以保證牢固性和氣密性，同時需要能夠抵抗特定環(huán)境下的腐蝕或輻射 。
3. 密封技術(shù)：過濾單元與箱體框架之間的密封是關(guān)鍵，北美通常采用液體（凝膠）密封，而歐洲則使用充氣氣囊，并進(jìn)行密閉性檢測 。
4. 原位消毒和在線檢漏功能：由于高效過濾器存在泄漏和表面微生物存活、繁殖的風(fēng)險，BIBO過濾器需要具備原位消毒和在線檢漏的功能，以滿足生物安全實驗室等高級別安全要求 。
5. 操作安全性：BIBO過濾器的設(shè)計要確保操作人員在更換過濾器時的安全，這通常涉及到使用特殊的安全袋和手套，以及確保操作簡便快捷 。
6. 維護(hù)和檢測的便利性：BIBO過濾器需要配備自動或手動掃描檢測單元，以便于隨時檢測過濾器的效率和安全性，同時保證檢測過程的密封性和安全性 。
7. 國際標(biāo)準(zhǔn)的遵循：BIBO過濾器的生產(chǎn)需要依據(jù)各國的核工業(yè)標(biāo)準(zhǔn)，如美國的ASME N509、ASME N510，或德國的DIN 25496等，這些標(biāo)準(zhǔn)對設(shè)備的性能和安全性有嚴(yán)格的要求 。
8. 箱體和氣密隔離閥的連接：箱體與氣密隔離閥之間采用法蘭連接，并使用特殊的密封墊圈進(jìn)行密封，以防止任何潛在的泄漏 。
9. 過濾器單元的組合方式：過濾單元的數(shù)量和組合方式?jīng)Q定了BIBO過濾器的風(fēng)量和尺寸，需要根據(jù)實際應(yīng)用需求合理設(shè)計 。
10. 檢測方法的創(chuàng)新：BIBO過濾器需要采用可以模擬并取代傳統(tǒng)氣溶膠檢測方法的檢測技術(shù)，以提高檢測效率和安全性 。
這些難點要求制造商具備高水平的工程設(shè)計能力、嚴(yán)格的質(zhì)量控制和對特定應(yīng)用環(huán)境的深入理解。
What are the key points in making bag-in-bag-out BIBO?
Working principle:
1. Bag entry: The new HEPA filter is placed in a special protective bag before installation. This bag is usually made of PVC or other durable material that seals and prevents contaminants from escaping.
2. Installation: Send the protective bag containing the new filter into the filter box through the BIBO interface, and install the new filter in place.
3. Bag out: When the filter needs to be replaced, use a protective bag to wrap the used filter and then remove it from the box. This ensures that contaminants are completely isolated during the entire replacement process and do not come into contact with the external environment.
Main feature:
- Safety: The BIBO system provides a safe replacement method, preventing the spread of contaminants and operator exposure. - Air tightness: The system design ensures complete isolation from the external environment, ensuring high air tightness.
- Easy maintenance: By using a protective bag, the filter replacement process is simplified, reducing maintenance time and costs.
- Wide applicability: Suitable for a variety of occasions requiring high safety, such as biosafety laboratories, medical facilities, pharmaceutical and chemical industries, etc.
Application scenarios:
- Biosafety laboratories: used to control the spread of highly pathogenic pathogens.
- Hospital isolation wards: used to prevent the spread of infectious pathogens through the air.
- Pharmaceutical industry: used to ensure the cleanliness of the production environment and prevent cross-contamination.
- Chemical industry: used to handle and discharge harmful chemicals to protect the environment and personnel safety.
Technical Difficulties
1. High air tightness requirements: BIBO filters need to be completely isolated from the outside air during installation, replacement and testing, which requires extremely high air tightness in the filter box and all connections.
2. Material selection: The box is usually integrally welded with stainless steel to ensure firmness and airtightness. It also needs to be able to resist corrosion or radiation in specific environments.
3. Sealing technology: The sealing between the filter unit and the box frame is the key. North America usually uses liquid (gel) sealing, while Europe uses inflatable air bags and performs tightness testing.
4. In-situ disinfection and online leak detection functions: Since high-efficiency filters have risks of leakage and surface microbial survival and reproduction, BIBO filters need to have in-situ disinfection and online leak detection functions to meet the needs of high-level biosafety laboratories and other Security requirements.
5. Operational safety: BIBO filters are designed to ensure operator safety when changing filters, which usually involves using special safety bags and gloves, as well as ensuring easy and quick operation.
6. Convenience of maintenance and testing: BIBO filters need to be equipped with an automatic or manual scanning detection unit to test the efficiency and safety of the filter at any time, while ensuring the sealing and safety of the testing process.
7. Compliance with international standards: The production of BIBO filters needs to be based on the nuclear industry standards of various countries, such as ASME N509, ASME N510 in the United States, or DIN 25496 in Germany. These standards have strict requirements on the performance and safety of the equipment.
8. Connection between the box and the air-tight isolation valve: The box and the air-tight isolation valve are connected by flange and sealed with a special sealing gasket to prevent any potential leakage.
9. Combination method of filter units: The number and combination method of filter units determine the air volume and size of the BIBO filter, which needs to be reasonably designed according to actual application requirements.
10. Innovation in detection methods: BIBO filters need to adopt detection technology that can simulate and replace traditional aerosol detection methods to improve detection efficiency and safety.
These difficulties require manufacturers to have a high level of engineering design capabilities, strict quality control and an in-depth understanding of specific application environments.
