TECHNICAL FIELD

[0002] In biochemical pharmaceutical, electronic industry, semiconductor, cosmetic and other laboratories or production workshops, clean workshops are widely used to ensure the cleanliness of equipment and products. Such workshops have strict control over internal controlled particle count, temperature, humidity, pressure, noise and other parameters. In particular, in the field of biological medicine, clean workshops need to meet the requirements of sterile environment. Therefore, before entering the clean workshop, the staff must go through multiple procedures such as shoe changing, clean clothing changing, hand disinfection, etc. At the same time, the water used in the workshop also needs to be subjected to high-level filtration and disinfection treatment to ensure that the production environment meets strict sterile standards.

[0003] In order to maintain the required cleanliness in the workshop, the existing technology generally uses an air filtration system to ensure the quality of the incoming and recirculating air. The air filtration system is usually composed of a fresh air filtration device and a return air filtration device. The fresh air filtration device is used to filter the outdoor incoming fresh air to remove particulate matter, microorganisms and other impurities therein; the return air filtration device is used to purify the indoor circulating return air. In addition, in order to further improve the air quality, a fresh air and return air mixing device and a secondary filtration device are usually added. The fresh air and return air mixing device can mix the treated fresh air and return air in a certain proportion to meet the temperature and humidity control requirements in the workshop; the secondary filtration device is used to filter the mixed air again, thereby further improving the cleanliness in the workshop.

[0004] However, the existing technology has the defect that the return air filtration device may not be completely filtered in actual application, resulting in that the air quality in the workshop cannot meet the high-standard cleanliness requirements, especially in the field of biological medicine, which may directly affect the quality and safety of the product.
