Purification Engineering Purification Workshop Design Key Points
Purification Engineering Purification Workshop Design Key Points1. Cleanroom Cleanroom System The air purification system in the room can be divided into horizontal laminar flow, vertical laminar flow, and turbulent flow. The selection of airflow form is based on conventions and depends on the working parameters of the room.2. Cleanliness and ventilation times The cleanliness of the room depends on the number of ventilation times per unit time. Therefore, the working nature of the room and the production process requirements should be carefully considered before determining the technical parameters of the purification system. 3. Structure To ensure that the airflow is almost undisturbed, structural design must be carried out. The necessary caution can prevent dust accumulation anywhere in the room. 4. Design plan To determine the design plan, the working nature of the room and the airflow conditions must be carefully considered. Workshops with large dust generation should not use ground air supply, and seminars with high cleanliness requirements should be as far away from other workshops as possible. 5. Materials The ceiling, wall, and floor materials of the clean room must be materials that are not easy to break, not easy to get particles, and almost dust-free. In addition, according to the different working conditions of the room, the chemical properties of the materials must also be considered to be stable. 6. Pressure and airflow To ensure the cleanliness of the room, it is necessary to prevent the outside polluted air from entering the room. To achieve this goal, the room must maintain positive pressure. To obtain the required room pressure, appropriate fresh air must be added. 7. Auxiliary equipment If necessary, some auxiliary equipment must be installed: such as air indicators at the fresh air outlet, transfer windows on the partitions, etc. These devices must be suitable for the requirements of the room, and their functions must be truly understood. 8. Control of people and objects People and objects are the main sources of dust in the clean room, so they must be fully controlled. For example, before entering the clean room, all people must pass through the clean system, change into dust-free clothes, and receive basic education on the functions of the clean system. 9. Water supply and drainage, air supply devices, and power supply According to the workshop to be operated, provide necessary water supply and drainage devices, air supply devices, and power supplies. These devices and the equipment involved must be easy to use and designed, and must not interfere with the air purification system. |
