Description

Air circulation disinfection equipment

Technical Field

The indoor environmental pollutants and pollution sources mainly comprise radioactive gas, mold, particulate matters, decoration residues, second-hand smoke and the like. In particular, in special environments such as hospitals, germs may be mixed in the air, so that the air is sterilized while being filtered.

In the prior art, ultraviolet rays are generally adopted to kill germs in the air, such as an ultraviolet air disinfection device disclosed in CN212679693U, and a fan is utilized to drive air to continuously flow through an ultraviolet lamp irradiation area for disinfection and sterilization. However, the air needs to be irradiated with ultraviolet rays for a long enough time, generally tens of seconds, to ensure the sterilizing effect. In the prior art, the straight cylinder type disinfection cavity is driven by the fan to quickly pass through air, so that the residence time is insufficient, and the disinfection effect is not ideal.

To solve this problem, common solutions are: 1. extending the length of the straight cylinder type disinfection chamber, but this increases the size of the disinfection apparatus considerably. 2. The suction force of the fan is reduced, and the method can prolong the time of air staying in the ultraviolet irradiation area, but the stirring effect of the air in the whole room is small due to the small air speed sprayed from the air outlet. The purified clean air is accumulated around the purifying equipment, and the air in other areas of the room is difficult to be disinfected and purified, so that the disinfection effect of the whole room is affected.
