Multistage air purification system

Abstract

The invention discloses a multistage air purification system which comprises a metal filtering net arranged at the position of a to-be-treated gas inlet. In the gas flowing direction, the inner side of the metal filtering net is sequentially provided with a nanometer Ag-TiO2 composite antibacterial material layer, deep frequency ultraviolet ray transmitting lamps, a carbon fiber filtering layer, a diatom pure filtering layer, a mayan blue filtering layer and an ePTFE porous glass fiber composite film layer; the multiple deep frequency ultraviolet ray transmitting lamps are sequentially distributed inside the system from top to bottom at equal intervals; and a clean air flowing-out opening is arranged outside the ePTFE porous glass fiber composite film layer. By means of the multistage air purification system, air is purified in an efficient, durable and circulated manner, anions beneficial to the human body can be released at the same time, and the multistage air purification system is multifunctional, can achieve efficient degerming, and can remove pm2.5 and formaldehyde.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a multi-stage air evolution system with the functions of highly efficient sterilization, PM2.5 removal and formaldehyde removal. Background technique [0002] In recent years, as the air pollution has become more serious, the content of pm2.5 in the air has risen sharply, and harmful substances such as formaldehyde and bacteria in various home decoration materials have continued to grow, it has become a luxury for people to breathe clean air , in this environment, the air purification device has become one of the indispensable electrical appliances in people's life. [0003] At present, the purification system of pure natural air purifiers on the market is mainly activated carbon and bamboo charcoal with physical adsorption function. However, when the adsorption of activated carbon and bamboo charcoal is saturated, it may also absorb harmful substances Re-release, so the adsorpti...

AI Technical Summary

Problems solved by technology

[0003] At present, the purification system of pure natural air purifiers on the market is mainly activated carbon and bamboo charcoal with physical adsorption function. However, when the adsorption of activated carbon and bamboo charcoal is saturated, it may also absorb harmful substances Re-release, so the adsorption effect is not stable

Moreover, although photocatalyst-based composite activated carbon and photocatalyst-based diatom purification products have also appeared on the market, they cannot achieve the desired effect from the perspective of their actual purification effects.

Moreover, the current air purification system can only purify a certain harmful substance in the air, and cannot effectively treat the harmful substances in the air at the same time.
