Clean room design and decoration project
The basic layout of the clean area is: the area of u200bu200bthe clean clean room modular should be reasonable, the layout of the indoor equipment should be compact, and the area should be minimized; the clean rooms of the same level should be adjacent to each other as much as possible; the facilities of different levels of cleanliness should prevent cross-contamination, and the rooms connected to each other There should be an isolation door between them, the door should be opened in the direction of high cleanliness, and the clean room must maintain a certain positive pressure; the static pressure difference between clean rooms of different cleanliness levels should not be less than 5Pa, and the static pressure between the clean room and the outdoor atmosphere The difference should be greater than 10Pa; there are generally no windows in the clean room, the door should be closed, the air valve should be installed at the entrance and exit of people and objects, and the illuminance should be greater than 300Ix; in order to reduce personnel pollution, the operator must wash, change clothes, and even ventilate before entering the clean room. The clothes should be specially used, the hair should not be exposed, and the skin should not be exposed as much as possible.
Materials and equipment need to be cleaned before entering the clean room. If they are placed in the clean room for a long time, they should be cleaned regularly. Liquid materials are generally sent into the sterile room while sterilizing in one pass. For example, the ampoules are washed, After drying, sterilization and cooling, the sterilized ampoules are sent to the aseptic room filling room by the transmission belt for packaging; the particle size distribution of the dust particles contained in the air is wide. The high-efficiency air purification system adopts a three-stage filtration device: primary-efficiency filtration→intermediate-efficiency filtration→high-efficiency filter, and the middle-efficiency air purification system adopts a secondary filtration device: primary-efficiency filtration→intermediate-efficiency filtration; clean rooms often use side and top filters. In the wind mode, the return air is generally installed under the wall. After the clean air sent by the high-efficiency filter enters the clean room, the arrangement of its flow direction directly affects the cleanliness of the room. There are two types of air flow: laminar flow and turbulent flow; Dust is not easy to spread to each other. Even if the airflow encounters dust-generating objects such as people and objects, the dust entering the airflow rarely spreads to the whole room, but flows out quickly with the parallel flow to maintain the cleanliness of the room. It is often used in Class A clean areas; The vertical laminar flow uses high-efficiency filters as the air supply ports, which are covered with the ceiling, and all the floors are return air openings, so that the air flows from top to bottom; flow in a horizontal direction. The turbulent air streamlines are in an irregular state, and the dust between each streamline is easy to diffuse to each other, and the turbulent flow can obtain B-D clean air. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean rooms and clean rooms.
The air purification and conditioning system is mainly to process the air entering the clean room. The air treatment adjusts the temperature, humidity and cleanliness of the outdoor air to the specified indicators of indoor operation through a series of treatments; There are three types of methods: centralized, semi-centralized and decentralized. The centralized purification air-conditioning system consists of primary and medium-efficiency air filters and temperature and humidity treatment equipment fans, coolers, heaters, and humidifiers to form an air-conditioning box, which is placed in the air conditioner. It is composed of pipes connected to the high-efficiency filter in the static pressure box at the air inlet of the air-conditioning room. The refrigeration of this system can be provided by the freezing station or the refrigerator installed in the air-conditioning room, and the heat source is provided by the boiler room or the heat exchange station, or in the The air conditioner is equipped with an electric heater.
