Air purification and design and decoration of dust-free pharmaceutical cleanroom
The purification air conditioning system cannot be combined with the general air conditioning system, because the air outlet of the purification air conditioning system is equipped with a high-efficiency air filter, while the general air conditioning system has no filter on the air outlet, and the air outlet of the high-efficiency air filter has resistance during operation. will increase, while the resistance of the air outlet of the general air conditioning system remains unchanged, so as the operating time increases, the air volume of the clean room may become smaller and smaller, and the air pressure in the room or area of u200bu200bthe clean room may occur. Variety. The cleanliness level, microbial control, temperature, humidity requirements, disinfection methods and disinfection frequency of the dust-free production area are quite different from those of the non-dust-free production area. In terms of energy saving, the purification air conditioning system serving two different areas should be set up separately.
High-level and low-level clean rooms, such as A, B level and C, D level, apart from different requirements for cleanliness level, temperature and humidity, separate setting will be beneficial to the operation and management of clean room purification and air conditioning system , When the air volume of the system is large, because the total air supply and return air ducts and the volume of the unit occupy a large space, and bring unfavorable factors to the strength performance, installation and maintenance operation of the unit, it is recommended to set them separately. The purification air conditioning system should make reasonable use of the return air. During the production process, such as the crushing, weighing, batching, mixing, granulating, tableting, coating, filling and other production processes or rooms of solid materials, various dusts are often emitted. , harmful substances, etc. In order to prevent cross-contamination caused by air circulation, all the air sent into the room is discharged; in the production of solid materials, dust is emitted in many production processes, so purifying the air conditioning system requires a large fresh air ratio, even As high as 60%-70%, the energy consumption is very large; if the dust and other substances in the return air of the air conditioner can be fully and effectively treated, so that it will no longer cause cross-contamination, it is possible to use the return air; it is necessary to improve the process and equipment. Comprehensive consideration should be given to the operation and operation of the system to determine whether it is economical and reasonable to adopt the return air utilization scheme. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for dust-free workshops and dust-free workshops.
The measures taken in the dust-free pharmaceutical cleanroom to prevent the backflow of outdoor air include: setting up a medium-efficiency air filter, which is the first choice for removing dust-containing exhaust air because it has the effect of filtering dust in the air; setting a check valve, its structure Simple, low cost, but poor sealing; set the electric airtight air valve interlocked with the exhaust fan to switch synchronously with the fan. In order to prevent the hot and humid air from condensing and condensing during the exhaust process, it will flow back along the inner wall of the exhaust pipe to the clean room and cause pollution. Therefore, the slope of anti-condensation water backflow is set along the exhaust direction, and the lowest point or accumulated water is set. Set up a drain.
