Design and installation of 100,000-level clean and dust-free workshop
Cleanliness class of clean room: class 100 > class 1000 > class 10,000 > class 100,000 > class 300,000, that is to say, the smaller the value, the higher the purification level and the higher the cleanliness, the higher the cost; Class 10,000 purification workshop refers to a clean workshop with air cleanliness of class 100,000, and the particles per cubic meter in the workshop are controlled within 10W; the pressure difference of clean workshops with the same cleanliness level remains the same. The pressure difference between the two should be ≥5Pa, and the difference between the clean room and the non-clean room should be ≥10Pa. Generally, it has to go through three filtration sections, including primary efficiency filtration, medium efficiency filtration, and high efficiency filtration. Airflow → primary efficiency purification → humidification section → heating section → surface heating section → surface cooling section → intermediate efficiency purification → fan supply air → pipeline → high efficiency Purify the air outlet → blow into the room to take away particles such as dust and bacteria → return air shutters → initial effect purification Repeat the above process to achieve the purpose of purification.
Microorganisms include bacteria, viruses, unicellular organisms, etc. The purification workshop project focuses on two indicators: planktonic bacteria and sedimentation bacteria. When doing sedimentation bacteria detection, special petri dishes are required. The nutrient substance is placed in the pharmaceutical cleanroom for a period of time. According to the number of bacteria growing in the nutrient substance, the number of settled bacteria in the air can be calculated. The temperature is generally controlled at 20-22°C in winter; 24-26°C in summer, with a fluctuation of ±2°C; the clean room humidity is controlled at 30-50% in winter and 50-70% in summer, with no special requirements for temperature and humidity When wearing clean work clothes, it is advisable to feel comfortable. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for 100,000-level clean workshops and dust-free workshops.
The cleanliness and ventilation time of each room in the clean room depends on the number of ventilations in a certain period of time, so carefully consider the work requirements of each room in the clean room may vary, as well as the production process
Then, it is required to determine the technical parameters of the purification system; in order to ensure that the air flow is almost undisturbed, it is necessary to carry out the structural design of the workshop, as well as the layout of the workshop to prevent the generation of airflow vortex; when the design scheme is determined, it must first be carefully considered The working nature of the room and the air flow condition, understand the overall layout and requirements, rooms with high cleanliness requirements should be as far away from other workshops as possible; pressure and airflow To ensure the cleanliness of the workshop, the seal of the workshop must be strong to prevent the airflow of external pollution from entering the workshop ; The materials used in the workshop wall and floor materials must be dust-free, corrosion-resistant, high-temperature resistant, not easy to break, not easy to generate static electricity, and make choices according to the different working conditions and actual conditions of the room.
It is beyond doubt that benefits extraction machine. Market sentiments are strong, especially in the light of growing extraction machine observed globally.
