Working principle of medical air purification and disinfection machine

The middle wavelength of the ultraviolet light emitted by the UV lamp is 253.7nm, belonging to the VU-C band of ultraviolet light.

Medical air purification and disinfection machine, specifically designed for hospitals, public places, living environments and other places, can purify and disinfect the air, quickly kill indoor bacteria, viruses, fungi, remove smoke, formaldehyde, benzene, ammonia and volatile organic compounds in the air, and thus clean the air.

1. UV rays

The middle wavelength of the ultraviolet light emitted by the UV lamp is 253.7nm, belonging to the VU-C band of ultraviolet light. It has the strongest sterilization power and can ionize organic molecules, bacteria, viruses, etc. in the air, causing them to differentiate and inactivate, thereby achieving the effect of disinfection and sterilization

2. HEPA efficient filtration

Using a pneumatic system to pass air through a high-efficiency filter (HEPA), based on the mechanism of coexistence of dust and bacteria in the air, various particulate matter floating in the air is filtered, captured, and collected. Its high-efficiency filtering material belongs to the resistance type dust collection, without any electron interaction, does not produce odor, and the efficiency will not decrease with the increase of use time.

3. Electrostatic dust collection module

Dust and pollutants in the air will ionize and change their direction of motion when passing through a high-voltage electric field, and then be captured. At this time, negatively charged ions will move towards the positive electrode plate under the action of the electric field force. According to the principle of positive and negative attraction, particles will be captured and adsorbed on the dust collection plate by the energy released by the high-voltage charge instantly, thereby achieving the effect of dust removal and sterilization.

4. Activated carbon honeycomb filter

The columnar activated carbon with high adsorption force and the treated porous ceramics are packed in the special plastic honeycomb, sealed with mesh cloth on both sides, and compounded with the photocatalyst foam metal nickel mesh. Good breathability, low air resistance, strong purification ability, and extremely strong antibacterial performance. It can effectively decompose various organic pollutants in the air, quickly adsorb various harmful gases such as benzene, formaldehyde, ammonia, and perform photocatalytic decomposition.
