Compared with foreign countries, the research and application of air cleaning technology in my country is relatively late compared with foreign countries. However, the dust-free and aseptic conditions of clean rooms are indispensable for most modern manufacturing industries. Without clean production conditions, the product may be contaminated and malfunction, or it may cause harm to the human body. With the industrial upgrading and product upgrading of the chip industry, LCD panel industry, biomedical industry and food processing industry in recent years, a large number of companies have built new high-standard clean workshops. The rapid development of science and technology, the application of nanotechnology, and the more sophisticated integrated circuits have made the electronics industry more and more demanding on cleanliness.
Clean room is also called clean room or clean room. The development of clean workshop technology has opened up new areas for industrial building design. It is the basis of pollution control. Without a clean room, it is impossible to mass-produce pollution-sensitive parts. The clean room state is divided into three types: empty state, static state and dynamic state:
Empty state: A clean room (facility) that has been constructed and can be put into use. It has all related services and functions. However, there are no equipment operated by operators in the facility.
Static: A clean room (facility) with various functions complete, properly set up and installed, and can be used or in use according to the settings, but there is no operator in the facility.
Dynamic: In a clean room in normal use, with perfect service functions, equipment and personnel; if necessary, normal work can be performed.
Clean room can be divided into laminar flow type and turbulent flow type. Laminar flow clean room means that the air flows from one side to the other side at the same speed, so that the dust particles or bacteria generated in the room will not scatter nearby and be pushed out. It may be filtered through the return air filter to reach a good quality. This method is more suitable for professional clean rooms with high cleanliness requirements. Turbulent flow clean room means that the air is filtered from the top of the clean room through the primary and middle-efficiency filter of the combined air conditioning unit, and the pressurized air is scattered to each room through the insulated air duct. Zui is finally sent into the clean room through the high-efficiency air outlet to achieve purification The effect of this air supply method is more common. The return air is usually made at the corner or the bottom of the column, and the whole return air; the air supply system of the clean room requires strict control of various air filters.
