How to design the clean area of purification project? The design of the clean area of the purification project is divided into the following points.
1、 The layout route of walkway is as follows:
1. Verandah surround type: verandah can have windows and no windows, and it is also used for visiting and placing some equipment. Some of them are equipped with duty heating in the verandah. The outer window must be double sealed.
2. Inner corridor type: the workshop of purification project is located in the periphery, while the corridor is located in the interior. The cleanliness level of this corridor is generally high, even the same level as the purification workshop.
3. Two end type: the clean area is set on one side, and the other side is set with quasi clean and auxiliary rooms.
4. Core type: in order to save land and shorten pipelines, the clean area can be taken as the core and surrounded by various auxiliary rooms and concealed pipelines. This way avoids the impact of outdoor climate on the clean area, reduces the energy consumption of heat and cold, and is conducive to energy conservation.
2、 Personal purification route
In order to reduce the pollution caused by human activities as much as possible during operation, the personnel must change the clean clothes and blow, shower and disinfect before entering the clean area. These measures are referred to as "personal purification".
The room where the clean clothes are replaced in the room for human clean use shall be ventilated, and the positive pressure shall be maintained on the entrance side and other rooms, and a little positive pressure shall be maintained on the toilet and shower, while the negative pressure shall be maintained on the toilet and shower.
3、 Material purification route
All kinds of objects must be purified before being sent to the clean area, which is referred to as "Wujing".
The material purification route and the human purification route should be separated. If the material and the human can only enter the clean area at the same place, they must also enter by door. The material should be subject to rough purification treatment first.
If the production line is not strong, the intermediate warehouse can be set in the middle of the material route.
If the production line is very strong, the straight through material route is adopted, and sometimes multiple purification and transfer facilities need to be set in the middle of the straight through route.
In the system design, due to a lot of raw particles will be blown off in the coarse and fine purification stage of the room, the negative pressure or zero pressure should be maintained in the relatively clean area. If the pollution risk is large, the negative pressure should also be maintained in the inlet direction.
