層流罩傳遞窗一體設(shè)備如何設(shè)計(jì)?

層流罩傳遞窗一體設(shè)備如何設(shè)計(jì)?

杰昊層流罩傳遞窗一體設(shè)備是一種集成了層流罩和傳遞窗功能的設(shè)備,通常用于需要高潔凈度環(huán)境的實(shí)驗(yàn)室或工業(yè)生產(chǎn)線。

以下是一些關(guān)鍵特點(diǎn)和功能:

 1. 層流罩(Laminar Flow Hood):提供局部的潔凈空氣環(huán)境,通過高效過濾系統(tǒng)(HEPAULPA過濾器)將空氣過濾后以層流方式向下流動(dòng),減少空氣中的微粒和微生物,確保操作區(qū)域的高潔凈度。

 2. 傳遞窗(Pass Box):作為連接不同潔凈等級(jí)區(qū)域的通道,允許物品從一個(gè)區(qū)域安全地傳遞到另一個(gè)區(qū)域,而不需要打開整個(gè)潔凈室或手套箱,從而減少環(huán)境之間的交叉污染。

 3. 一體化設(shè)計(jì):將層流罩和傳遞窗集成在一個(gè)設(shè)備中,節(jié)省空間,同時(shí)提供更高效的操作流程和更好的潔凈度控制。

 4. 密封性能:確保傳遞窗在關(guān)閉狀態(tài)下能夠完全密封,防止污染物的侵入。

 5. 材料選擇:根據(jù)應(yīng)用需求選擇合適的材料,一般采用304不銹鋼,部份采用316L,以滿足耐腐蝕、耐高溫等特性。

 6. 操作便利性:設(shè)計(jì)時(shí)考慮到操作人員的使用習(xí)慣,確保易于操作,如自動(dòng)門、觸摸屏控制等。

 7. 附加功能:可選包括壓力控制、氣體凈化、溫度和濕度調(diào)節(jié)等,以適應(yīng)特定的工藝要求。

 8. 維護(hù)和清潔:設(shè)備應(yīng)易于清潔和維護(hù),以保持其性能和延長(zhǎng)使用壽命。

 這種一體化設(shè)備廣泛應(yīng)用于半導(dǎo)體制造、生物制藥、醫(yī)療設(shè)備制造等領(lǐng)域,為敏感材料的加工和處理提供了一個(gè)安全、潔凈的環(huán)境。

 杰昊層流罩傳遞窗一體設(shè)備的設(shè)計(jì)存在一些技術(shù)挑戰(zhàn)和難點(diǎn),主要包括以下幾個(gè)方面:

 1. 潔凈度的保證:層流罩傳遞窗需要維持B級(jí)潔凈度,這要求內(nèi)部的空氣必須通過高效過濾器進(jìn)行過濾,以去除空氣中的塵埃、煙霧、細(xì)菌等有害物質(zhì) 。

 2. 密封性能:設(shè)計(jì)時(shí)需要考慮到內(nèi)外雙層殼體的密封性,內(nèi)部四周圓弧處理以保證無縫隙連接,這對(duì)于防止污染物的侵入至關(guān)重要 。

 3. 氣流控制:采用層流設(shè)計(jì),氣流流向需采用上送下回模式,底部采用304不銹鋼冷軋板沖孔設(shè)計(jì),并設(shè)置加強(qiáng)筋以控制風(fēng)速在0.38-0.57m/s 。

 4. 過濾器的選擇與維護(hù):初效過濾器采用G4,高效過濾器采用H14,需要確保過濾器的高效性和便于維護(hù)更換

 5. 電子控制與互鎖系統(tǒng):配置內(nèi)置式電子門互鎖,以及紫外燈和照明燈的單獨(dú)控制開關(guān),確保操作的安全性和便捷性 。

 6. 維護(hù)與檢修:高效過濾器需要能夠單獨(dú)從上部箱體進(jìn)行拆卸和安裝,便于維護(hù)和更換濾器,同時(shí)在傳遞窗下部設(shè)置檢修口,用于風(fēng)機(jī)的檢修 。

 7. 噪聲控制:傳遞窗正常運(yùn)行時(shí)噪聲需控制在<65db,以保證工作環(huán)境的舒適性 。

8. 材料選擇:內(nèi)外表面及框架通常采用304不銹鋼冷軋板,板材厚度和表面處理需要滿足特定的光潔度要求 。

9. 傳感器校驗(yàn)與驗(yàn)證:所有傳感器必須經(jīng)過具有法定資質(zhì)的校驗(yàn)單位校驗(yàn),并提供校驗(yàn)記錄和合格證書 。

10. 現(xiàn)場(chǎng)測(cè)試與驗(yàn)證文件:設(shè)備安裝完畢后,供應(yīng)商需要對(duì)每臺(tái)潔凈傳遞窗進(jìn)行現(xiàn)場(chǎng)測(cè)試,并提供符合GMP標(biāo)準(zhǔn)的驗(yàn)證文件資料

11. 美觀與實(shí)用性:設(shè)備表面應(yīng)光滑,無毛刺,不積塵,易清潔,所有縫隙采用食品級(jí)中性密封膠密封,同時(shí)電線隱藏不得外露,確保設(shè)備的美觀與實(shí)用性 。

 這些設(shè)計(jì)難點(diǎn)需要通過技術(shù)創(chuàng)新和精細(xì)的工程設(shè)計(jì)來克服,以確保層流罩傳遞窗一體設(shè)備能夠高效、穩(wěn)定地運(yùn)行,并滿足特定的工藝要求和安全標(biāo)準(zhǔn)。 



 How to design a integrated equipment of laminar flow hood and pass box?


The Laminar Flow Hood Pass Box Integrated System is a specialized apparatus that combines the capabilities of both a laminar flow hood and a pass box. It is extensively utilized in settings that demand stringent cleanliness standards, such as research laboratories and manufacturing facilities.

Here are its core attributes and functionalities: 

1. Laminar Flow Hood: Provides a local clean air environment, where air is filtered through a high-efficiency filtration system (HEPA or ULPA filters) and flows downward in a laminar flow pattern, reducing particles and microorganisms in the air and ensuring high cleanliness in the operational area. 
2. Pass box: Serves as a passage connecting different cleanliness grade areas, allowing items to be safely transferred from one area to another without opening the entire cleanroom or glove box, thereby reducing cross-contamination between environments.

3. Integrated Design: Combines the laminar flow hood and pass box into one piece of equipment, saving space and providing a more efficient operation process and better cleanliness control.

4. Sealing Performance: Ensures that the pass box is completely sealed when closed to prevent the intrusion of contaminants.

5. Material Selection: Chooses suitable materials according to application requirements, generally using 304 stainless steel, and some parts using 316L, to meet characteristics such as corrosion resistance and high-temperature resistance.

6. Operation Convenience: The design takes into account the habits of operators to ensure easy operation, such as automatic doors, touch screen controls, etc.

7. Additional Features: Options may include pressure control, gas purification, temperature and humidity regulation, etc., to adapt to specific process requirements.

8. Maintenance and Cleaning: The equipment should be easy to clean and maintain to keep its performance and extend its service life.

This integrated equipment is widely used in fields such as semiconductor manufacturing, biopharmaceuticals, and medical equipment manufacturing, providing a safe and clean environment for the processing and handling of sensitive materials.

The design of the Laminar Flow Hood Pass box Integrated Equipment has some technical challenges and difficulties, mainly including the following aspects:

1. Cleanliness Assurance: The laminar flow hood pass box needs to maintain B-level cleanliness, which requires the internal air to be filtered through high-efficiency filters to remove harmful substances such as dust, smoke, and bacteria from the air.

2. Sealing Performance: The design needs to consider the sealing of the inner and outer double-shell bodies, with rounded corners inside to ensure seamless connections, which is crucial for preventing the intrusion of contaminants.

3. Airflow Control: Using a laminar flow design, the airflow direction should adopt a top-to-bottom return mode, with the bottom made of 304 stainless steel cold-rolled plate with punched holes, and reinforcement ribs are set to control the wind speed at 0.38-0.57m/s.

4. Filter Selection and Maintenance: The preliminary filter uses G4, and the high-efficiency filter uses H14, which needs to ensure the efficiency of the filter and facilitate maintenance and replacement.

5. Electronic Control and Interlocking System: Equipped with a built-in electronic door interlock, as well as separate control switches for UV lights and illumination, ensuring the safety and convenience of operations.

6. Maintenance and Repair: The high-efficiency filter needs to be detachable and installable from the upper part of the box for easy maintenance and filter replacement, and a maintenance port is set at the bottom of the pass box for fan maintenance.

7. Noise Control: The noise of the pass box during normal operation needs to be controlled at less than 65db to ensure the comfort of the working environment.

8. Material Selection: The inner and outer surfaces and frames are usually made of 304 stainless steel cold-rolled plate, and the thickness of the plate and surface treatment need to meet specific gloss requirements.

9. Sensor Calibration and Verification: All sensors must be calibrated by a legally qualified calibration unit and provide calibration records and certificates.

10. On-site Testing and Verification Documents: After the equipment is installed, the supplier needs to conduct on-site testing for each clean pass box and provide verification documents that meet GMP standards.

11. Aesthetics and Practicality: The surface of the equipment should be smooth, without burrs, easy to clean, and all seams should be sealed with food-grade neutral sealant, while the wires should be hidden and not exposed to ensure the aesthetics and practicality of the equipment.

These design difficulties need to be overcome through technical innovation and meticulous engineering design to ensure that the Laminar Flow Hood Pass box Integrated Equipment can operate efficiently and stably, and meet specific process requirements and safety standards.
