Nano-titanium dioxide forms a sol-like absorption liquid under the action of a dispersant, and the catalytic efficiency of the sol-like absorption liquid is much higher than that of a traditional nano-scale titanium dioxide filter.

In the absorption tower type air purification device of this embodiment, organic pollutants refer to the organic substances released in construction, decoration and furniture, such as stupid, formaldehyde and ammonia, which are harmful to human body, and degraded organic pollutants refer to organic pollutants that are absorbed by the absorption liquid. Nano-titanium dioxide and energy are degraded into carbon dioxide, water, nitrogen and other non-pollutants. Specific degradation of organic pollutants means that in the absorption tower degradation system 2, only organic pollutants in the air are degraded, and are not used to remove particulate matter in the air and Other harmful inorganic substances contained in the air.

In the absorption tower type air cleaning device of the present embodiment, the air that enters the first chamber shell 21 from the air inlet 11 through the first air inlet is discharged from the air outlet 12 through the first air outlet under the effect of the fan 5, and the fan 5 makes The air is more circulated, and the air circulation increases the reaction time and area of the organic pollutants and the nano-titanium dioxide in the absorption liquid, thereby increasing the degradation efficiency.
