The air purification system in the purification workshop is a comprehensive system that controls pollutants such as particles, microorganisms, and harmful gases within specific standards through multi-stage filtration, optimized airflow organization, and intelligent control technologies. Botai editor will take you to learn about relevant knowledge.

1、 Core components of the system

1. Multi level filtering module

Primary filter: intercepts particles with a diameter ≥ 5 μ m to protect the precision filter.

‌

Medium efficiency filter: filters 1-5 μ m particles to reduce the load of high-efficiency filters.

Efficient filter: With a filtration efficiency of 99.97% for particles ≥ 0.3 μ m, it is used in high cleanliness areas. ‌

Ultra efficient filter: filters particles ≥ 0.12 μ m, used in ultra clean environments such as electronic chip manufacturing.

2. Circulation and air supply system

The fan drives air flow and achieves uniform air supply through air ducts and vents. The combination of return air system and new air outlet design ensures air circulation efficiency.

3. Auxiliary purification equipment

UV sterilization lamps are installed in the air outlet or circulation system to inactivate microorganisms in the air. Ozone generator removes odors and harmful gases such as formaldehyde and benzene.

4. Intelligent control system

Real time monitoring of temperature, humidity, pressure difference, particulate matter concentration and other parameters, and automatic adjustment of operating status. Equipped with sensors and control panel, supporting remote monitoring and alarm functions.

2、 Key technical points

1. Airflow organization design

Unidirectional flow: suitable for high cleanliness areas such as photolithography and pharmaceuticals, where air carries away pollutants.

Non unidirectional flow: used in auxiliary areas to achieve local purification through reasonable arrangement of air supply/return ports.

2. Parameter control standards

Cleanliness classification is divided according to standards, achieved through the number of air changes and filtration accuracy. Differential pressure control prevents external pollution from infiltrating, and temperature and humidity are controlled within a certain range.

3. Material and structural optimization

The walls are made of thick sandwich color steel plates, and the floor is made of epoxy self leveling or anti-static flooring to reduce dust accumulation. The air supply duct is made of galvanized steel plate, and the air outlet is designed with stainless steel or painted aluminum material for easy cleaning.

3、 Typical application scenarios

1. Laboratory and Hospital: Maintain sterile operating conditions through HEPA filtration and positive pressure environment.

2. Pharmaceutical industry: Removing chemical odors and microorganisms through water mist filtration and ozone sterilization.

3. Electronic chip manufacturing: Adopting ULPA filters and vertical laminar flow design to ensure that the concentration of 0.12 μ m particles meets the standard.

4. Food processing: Combining UV sterilization with efficient filtration to prevent microbial contamination, while controlling workshop humidity and mold resistance.
