  • 空气净化工程的应用领域包括哪些?

      随着半个多世纪的发展,空气净化工程的应用越来越广泛,技术要求也越来越复杂。目前,其具有代表性的应用领域是微电子工业、医药卫生和食品工业。其应用领域主要包括:
      With the development of more than half a century, the application of clean technology is more and more extensive, and the technical requirements are more and more complex. At present, its representative application fields are microelectronics industry, medicine and health and food industry. Its application fields mainly include:
      1. 微电子工业
      1. Microelectronics Industry
      微电子行业是对洁净室要求最高的行业。随着大规模集成电路(LSI)和VLS1的发展,对粉尘控制的要求越来越高。在IC制造过程中,集成度越高,图形尺寸(以线宽表示)越薄,洁净室受控粒度尺寸越小(通常为线宽的1/10),粉尘含量越低。此外,现代工业液晶、光纤生产,对洁净度要求相同。
      Microelectronics industry is the most demanding industry for clean rooms. With the development of large scale integrated circuit (LSI) and VLS1, the requirement of dust control is getting higher and higher. In IC manufacturing process, the thinner the graphic size (expressed by line width) is, the smaller the controlled particle size (usually 1/10 of line width) is, and the lower the dust content is. In addition, modern industrial liquid crystal and optical fiber production require the same cleanliness.
      2. 医疗行业
      2. Medical industry
      (1)药品生产中国的《药品生产管理规范》(GMP)已在全国范围内实施,对相应的工艺和生产环境提出了不同程度的洁净要求。针对原料的配制、粉末、注射、片剂、大输液的生产、灌装等工艺,制定了洁净区和控制区的清洗标准。除了限制空气中灰尘颗粒的大小和数量,生物颗粒(细菌的数量)也有明确的限制。
      (1) The Pharmaceutical Production Management Specification (GMP) of China has been implemented nationwide, and different cleanliness requirements have been put forward for the corresponding process and production environment. In view of the preparation of raw materials, powder, injection, tablet, production of large infusion, filling and other processes, the cleaning standards of clean and controlled areas were formulated. In addition to limiting the size and quantity of dust particles in the air, biological particles (the number of bacteria) also have clear limits.
      (2)医院白血病治疗室、烧伤病房、手术室也必须根据具体情况采取空气净化工程,防止空气中的细菌感染,控制治疗环境。
      (2) Hospital leukemia treatment rooms, burn wards and operating rooms must also adopt air purification projects according to specific conditions to prevent bacterial infection in the air and control the treatment environment.
      3.食品行业
      3. Food industry
      无菌灌装是食品工业中最具代表性的清洁技术应用。食品的无菌包装(如软包装鲜榨果汁、鲜奶等)在保持食品的色、香、味、营养等方面比高温杀菌罐头食品要好得多。无菌包装是在清洁的环境中进行包装的过程。除无菌灌装外,空气净化工程在食品酿造发酵过程中对纯菌种的培养、分离、接种和膨大,起到了防止细菌污染、提高产品质量的重要作用。
    空气净化工程
      Sterile filling is the most representative application of clean technology in food industry. Sterile packaging of food (such as soft packaging fresh juice, fresh milk, etc.) is much better than high temperature sterilization canned food in maintaining the color, aroma, taste and nutrition of food. Aseptic packaging is a process of packaging in a clean environment. In addition to aseptic filling, air purification engineering plays an important role in the cultivation, isolation, inoculation and expansion of pure bacteria in food fermentation process, preventing bacterial contamination and improving product quality.
      4. 生物安全
      4. Biosafety
      在基因工程、医学、病理学、分子生物学、国防科研、等,通常需要在无菌无尘环境中经营,一方面要求标本从微生物污染,另一方面需要研究材料,如肿瘤病毒、病原菌的风险高,放射性物质,如不溢出,危害操作人员的健康和污染环境。对于这种实验操作,一般需要两级隔离。在第一阶段,生物安全工作柜通常用于隔离工人与病原体和其他危险标本。第二层是将实验室工作区与其他环境隔离。这种实验室不同于一般的洁净室,它处于负压状态。
      In genetic engineering, medicine, pathology, molecular biology, national defense research, etc., it is usually necessary to operate in a sterile and dust-free environment. On the one hand, specimens are required to be contaminated by microorganisms, on the other hand, research materials, such as cancer viruses and pathogens, are at high risk. Radioactive substances, if not spilled, endanger the health of operators and the pollution ring. Environment. For this kind of experimental operation, two-stage isolation is generally required. In the first stage, biosafety cabinets are usually used to isolate workers from pathogens and other dangerous specimens. The second level is to isolate the laboratory workspace from other environments. This kind of laboratory is different from the general clean room, it is in a negative pressure state.
      5. 实验动物饲养
      5. Feeding of experimental animals
      为了保证药品和食品检验的长期安全性和病理学研究结果的可靠性,要求实验动物在清洁的环境中饲养和繁殖。从控制微生物的角度看,医学和生物实验用实验动物的饲养繁殖环境可分为三种类型:隔离系统、半隔离系统和开放系统。前两种系统要求动物无菌(包括细菌、病毒寄生虫等),或者只携带少量已知微生物,或者不携带某些致病菌,等等。
      In order to ensure the long-term safety of drug and food inspection and the reliability of pathological research results, laboratory animals are required to breed and reproduce in a clean environment. From the point of view of controlling microorganisms, the breeding environment of experimental animals for medical and biological experiments can be divided into three types: isolation system, semi-isolation system and open system. The first two systems require animals to be sterile (including bacteria, viral parasites, etc.), or to carry only a small number of known microorganisms, or not to carry certain pathogenic bacteria, etc.
      空气净化工程还广泛应用于航空航天、精密机械、仪器仪表、精细化工等行业。
      Air purification engineering is also widely used in aerospace, precision machinery, instruments, fine chemicals and other industries.
