Clean room purification project design must first understand the purpose of the designed clean room purification project , usage conditions, production process characteristics, etc. For example, the design is a clean room purification project for integrated circuit production. First of all, we must understand the characteristics of the product - integration, shape and size and production process characteristics; the requirements for clean room purification engineering - air cleanliness level, temperature and humidity and its control range, anti-microvibration, anti-microbial Supply requirements for static electricity and high-purity substances, etc.; secondly, it is necessary to fully understand the production process, process equipment and assumptions about the process layout that the owner intends to adopt. After that, the designer should work with the owner to determine the division of each functional area of the clean workshop, determine the air cleanliness levels of various production processes (rooms) and various control parameters - temperature, relative humidity, pressure difference, micro vibration, high The purity and impurity content of pure substances; preliminary selection of the air flow pattern of the clean room purification project and preliminary estimation of the purification air-conditioning system and comparison and determination of design proposals; the layout and space layout of the clean workshop must be arranged first. The rational layout of the product production area and the personal production auxiliary area, the power utility area, is usually in compliance with the production process of the product, and is conducive to the operation and management of product production while ensuring the requirements of the product production environment, which is conducive to saving energy and reducing costs. Cost of production. When carrying out the floor plan of a clean room purification project, it must comply with various requirements related to production safety, fire protection, environmental protection and occupational hygiene in the current national regulations; when carrying out the floor plan of a clean room purification project, full consideration should be given to arrangements for the flow of people and logistics ． Try to be short and smooth. When designing the space, reasonable arrangements for various pipelines and logistics transportation in the product production process and clean room purification project should be considered. After determining the plane and space layout of the clean workshop, the design content, technical requirements and related issues that should be paid attention to in the design are proposed for each major involved in the clean room purification engineering design.
Clean room purification engineering design is a comprehensive design technology completed by related majors. It is similar to the design of a shipyard industrial plant, but it also has its own characteristics. Its main characteristics are as follows.
() Determine the control objects and technical requirements of the designed clean room purification project based on the category, variety or usage of the products to be produced by the clean room purification project. For example, for biological clean room purification projects, the control objects are dust particles and microorganisms in the air; biological clean room purification projects for different products or purposes have requirements for air cleanliness levels, types and concentrations of microorganisms contained in the air, and pressure differences, etc. Don't ask. Another example is the clean room purification project for integrated circuit production. The control objects are mainly dust particles in the air; the requirements for air cleanliness level, anti-microvibration, high-purity substances, etc. are different according to the characteristic size and integration level of the integrated circuit and should be determined by the product variety of the specific factory.
() In order to ensure the necessary air cleanliness in the clean room purification project, all professional designs involved in the design of the clean room purification project should take appropriate and reliable technical measures to reduce or prevent indoor dust generation and breeding. Microorganisms reduce or prevent the introduction of particulate microorganisms or materials that may cause cross-contamination into the clean room purification project. Effectively discharge particulate microorganisms in the room to reduce or prevent them from staying in the clean room purification project. When cross-contamination of brittle dust particles or materials may endanger product rainfall or personal safety. Safe and reliable technical measures should also be taken to prevent cross-contamination, such as strictly controlling the static pressure difference between different clean room purification projects, reasonably dividing the purification air-conditioning system as required, and properly designing the return air system.
