Cleanroom purification engineering design and construction of what to do before the preparation?
Cleanroom purification engineering design and construction of what to do before the preparation?1. Collect data and information related to the production process indoor temperature and humidity of the base and precision, which need to be repeated with the process designers to determine and set reasonable parameters, do not pursue high standards, because the base and precision of the investment and operating costs have a greater impact, but to meet the basic requirements of the process is necessary.2. Collect the meteorological data on the location of the cleanroom purification project and the surrounding environment Outdoor design parameters in addition to year-round meteorological information, also need to collect the local environment, such as the concentration of dust which will affect the product and production process of the concentration of various gases. The distance of the railway, wharf, airport, and other transport hubs and traffic routes around the clean room purification project. Factories around the clean room purification project. Warehouse. Yard, good to stay away from these places, such can not stay away, take appropriate measures, such as a new air inlet filter level according to the measured data to determine, but also consider whether it is necessary to add chemical filters. Collection of waste heat generated in the production process and toxic and hazardous waste gas-related information 3. Determine the temperature of the waste heat gas and the amount of exhaust air. 4. Concentration, temperature, and hazardous level of toxic and hazardous gases and the volume of exhaust air, and to consider the countermeasures for treatment. Collect the requirements of the production process for electricity, water, and special gases and bulk gases Collection of clean room purification engineering architecture, structure, and process design of the flat section plan 5. Process design, cleanroom purification engineering decoration for a wide variety of processes, but the general principle is the installation and maintenance of production process equipment, production process flow, operating procedures, personnel flow routes, and material transfer arrangements should be avoided to avoid the occurrence of airflow interference and cross-contamination occurs. 6. To meet the production process and micro-vibration control, noise control and other requirements under the premise of high air cleanliness requirements of the electronics factory clean room purification project decoration (area) should be close to the air-conditioning plant layout, the air cleanliness level of the same process or work (area) should be arranged centrally. 7. According to the process design requirements should be set up for transport, installation, and maintenance of the channel or access door. 8. Personnel in and out of the clean room purification project decoration should set up personnel purification devices. 9. Materials, and equipment in and out of the clean room purification project decoration should be set up to purify the facilities and set up an airlock room or transfer window. 10. Clean area set up vacuum pump, there should be oil removal devices, the exhaust should be connected to the outdoors, and the transmission of combustible gases in the system, the concentration of which exceeds the lower limit of 20% of the explosion should be the tail gas treatment device, should be removed or diluted combustible gas composition, the transmission of flammable and spontaneous combustion of chemicals or a high concentration of oxygen should be used in the non-combustible pumping oil, and configuration of nitrogen purge control valve, and interlocked with the operating system of the process equipment. |
