Various filter sterilization technology in Dongguan clean room


Various filter sterilization technologies in Dongguan clean room:

1. Dongguan dust-free workshop adopts high-efficiency filtration and sterilization technology: the air is cleaned mainly by high-efficiency or ultra-high-efficiency filtration equipment, which transports clean air to a specific environment and can maintain the cleanliness of the air. Filtering clean principle: ① mesh interception; ② sieve mesh retention; ③ electrostatic attraction retention; ④ inertial collision and Brownian motion retention. Therefore, filtration and cleaning technology is the result of a comprehensive effect.

2. Filter media structure: Most of the filter media used in biological clean rooms are high-efficiency or ultra-efficient filter media. The filter media used are: glass wool filter media, high-grade pulp filter media, asbestos fiber filter media, and perchloroethylene fiber filter media. Wait. The retention rate of 0.5 μm particles in the air by high-efficiency filter media can reach 90% to 99%, and the ultra-high efficiency filter media can retain more than 99.9% of 0.3 μm particles.

3. Local purification, clean laminar flow hood: The clean laminar flow hood is a local air purification device in hospitals. Generally, it can form a vertical laminar flow mode, and a transparent curtain is used around it. High cleanliness (10,000 to 100) air can be maintained in the entire hood. This clean laminar flow hood can be used for the treatment and protection of patients with low immune function, so it is also called as sterile bed laminar flow hood.

4. At present, there is a three-stage purification device, namely pre-filtration-high-efficiency filtration-activated carbon adsorption, combined positive ion electrostatic adsorption and sterilization, and high-volume air purification to ensure the number of indoor air purification, which better solves the hospital's key Departments such as the operating room, ICU, maternal and infant ward, hemodialysis room and other people with continuous air disinfection problems can make the hospital's indoor air purification level of 100,000 to 10,000.

5. Purification operation table: Dongguan clean room adopts horizontal or vertical laminar flow to purify the air inside the box, which can make the purification in the operation table reach a very high level. Electrostatic adsorption sterilization and purification technology: Electrostatic adsorption sterilization is based on the principle of industrial electric dedusting, and it has some innovations in miniaturization technology.
