Problems solved by technology

Since the concentration of pollutants in the air is not constant, and the treatment efficiency of the air purification device is basically constant once it is set, when the concentration of pollutants in the air suddenly increases at a certain moment, the air purification device cannot All pollutants are effectively purified, causing the pollutants to be discharged into the air again

Abstract

The invention discloses an air purifying method based on photocatalysis and reversible adsorption. According to the air purifying method, a reversible adsorbing component firstly adsorbs a certain amount of pollutants in air, so that pollutant concentration of the air passing through a photocatalysis component is lowered, when follow-up air containing different pollutants higher in boiling point or same pollutant lower in concentration flows into an air purifying device, pollutants adsorbed in the reversible adsorbing component is promoted to desorb, and by continuously subjecting follow-up pollutants in the air to photocatalyst catalysis, all the air purifying device is ensured to purify all the pollutants more effectively.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an air purification method based on photocatalysis and reversible adsorption. Background technique [0002] With the improvement of living standards and the acceleration of modernization, people pay more and more attention to air pollution. Vehicle exhaust and home decoration often produce polluting gases, such as formaldehyde, toluene, xylene and other organic pollutants, such as NO X , SO 2 、H 2 S, NH 3 Such inorganic pollutants seriously affect the air environment and pose a threat to human health. [0003] Photocatalysis technology has been widely used in the field of air purification devices. Photocatalysis is a general term for photo-semiconductor materials with photocatalytic function represented by nano-scale titanium dioxide. It can produce strong catalytic degradation function: it can effectively degrade toxic and harmful gases in the air; it can effectively kill a v...
