Air purification device {APPARATUS FOR AIR PURIFICATION}

The present invention relates to an air purifier.

The environment is being destroyed by exhaust gas emitted due to rapid industrialization. Due to environmental destruction, modern society is experiencing inconveniences in various places and making various efforts to overcome them.

Nano-micro bubbles refer to microbubbles of hundreds of nm to 10 μm. Unlike normal bubbles, millibubbles, which rise rapidly in water and rupture on the surface, nanobubbles have a small volume, so they have little buoyancy and rise to the surface very slowly, so they remain in a bubble state for a long time underwater. In particular, it has characteristics such as gas dissolution effect, self-pressurization effect, and electrification effect, so it is highly applicable to various fields such as sewage treatment facilities, advanced water treatment facilities, soil purification, fisheries and agriculture, drainage treatment and cleaning. .

Hydroxyl radicals are substances produced by the reaction of moisture, oxygen, nitrogen, ozone, etc. in the air with ultraviolet rays. It is a reactive substance with strong oxidizing power and has strong sterilizing, deodorizing and oxidizing power.

In addition, it has been proven that hydroxyl radicals are harmless to the human body and effectively sterilize pathogens, viruses and fungi.
